19 Claims.

This invention relates generally to brush making machines and in particular to a brush making machine in which a series of related operations are successively performed on a brush block to complete a brush. This application is a, continuation of application Serial No. 480,353, flied March 24, 1943, now abandoned.

The prior art machines for making brushes in a series of operations successively performed on a brush block by related operating units, such for example as machines for making toothbrushes and the like, include relatively complicated and bulky mechanism for moving a brush block from one operating unit to a next related operating unit and for successively moving a brush block, in a predetermined path, to a plurality of operating positions relative to the same operating unit. As a result of this complicated mechanism the initial cost of the machine, as well as the cost of servicing and attention required to maintain an efllcient operation of the machine, is greatly increased. Also the complexity of these mechanisms appreciably reduces their production as well as their flexibility for application to brushes having different bristle arrangements or patterns thereon.

Further, in the prior-art machines of this type which use a straight anchor for retaining a bristle tuft in the brush block, considerable difllculty has been encountered in positively providing for the insertion of the anchor lengthwise into the brush block. The mechanism for inserting the anchor in the brush block usually consists of a pair of jaws having a groove in each closing portion for supporting and guiding the straight anchor at its ends while it is driven lengthwise from the jaws or guides into the brush block by a driving rod acting on a longitudinal side of the anchor.. If the anchor is initially tilted or misaligned relative to a plane which is substantially normal to the inner faces of the closing portions of the jaws or guides, this misalignment is generally increased or aggravated rather than corrected when the driving rod engages and pushes the anchor, so that the anchor is oftentimes driven into the brush block when it is in a substantially It is apparent of course that when driven in this position the anchor fails entirely in its function to retain or anchor a corresponding bristle tuft in the brush block.

It is an object of this invention, therefore, to provide an improved brush making machine.

' It is a further object of this invention to provide a brush making machine having a continuously rotating rotary table for carrying the brush blocks, in which a brush block is adjustably moved relative to the table and to an operating unit, during rotation of the table, to continuously position thebrush block as it passes an operating unit so that like operations are performed on the brush block along a predetermined path.

Yet a further object of this invention is to provide a brush making machine having a rotary table in which a selected positioning of the brush block relative to the table and to an operating unit is accomplished during the continuous rotation of the table in a single direction.

Another object of this invention is to provide a brush making machine having a rotary table for carrying a brush block. in which means are provided to successively move the brush block from one operating unit to a next related operating unit, and to selectively position the brush block to have a series of like operations performed thereon along a predetermined pattern, all while the table is intermittently but continuously rotated in a. single direction.

A still further object of this invention is to provide in a brush making machine means providing for an anchor of straight form being always driven substantially lengthwise into a brush block.

Another object of this invention is to provide, in a, machine for making brushes having straight anchoring means for holding a bristle tuft therein, means for locating the anchor in the anchor inserting means such that the anchor is always inserted in a lengthwise position within the brush block.

A feature of this invention is found in the provision of a brush making machine havinga rotary table, in which a brush block holder is movably supported on the table and adjustable during rotation of the table by stationary means adjacent the table to define a predetermined path of travel of the brush block relative to an operating unit.

Yet another feature of this invention is found in the provision of a brush making machine, in which an anchor of straight form is initially positioned in anchor inserting means by combination anchor forming and carryi g means, such that it is always located in a plane substantially normal to the inner faces of the closing portions of the jaws prior to the engagement of the anchor with an anchor driving rod. Further objects, features, and advantages of this invention will become apparent from the following description when taken in connection with the accompanying drawings, in which:

Fig. 7 is a detailed elevational view of the tuft and anchor inserting means showing the jaws thereof in a position for receiving the anchor and a corresponding bristle tuft therein;

Fig. 8 is illustrated similarly to Fig. '7 showing the jaws in a closing position on an anchor and a. bristle tuft; and

Fig. 9 is a detailed fragmentary elevational view partly in section showing the assembly arrangement of a tuft packing and picker mechanism, tuft and anchor inserting jaws, and a tumbler unit, these mechanisms being shown in relation to a brush handl or block located on the rotatable machine table.

In the practice of this invention there is provided a simple and efliciently operated brush making machine which in a continuous automatic operation requiring only the feeding of brush blocks or handles to the machine and the removal therefrom of the finished brush by an operator, acts otherwise to automatically adjust a handle carried on a rotary table for successive operations thereon by an operating unit, to drill spaced holes in tWo rows in the handle, to separate substantially measured tufts of bristles from a bristle holding magazine, insert the tufts within the rows of holes in the handle, secure the tufts within the handle by means of a wedging or anchoring pin of straight form, uniformly comb the bristles and then trim the bristles to the same height. All of the operating units for accomplishing the above defined operations are arranged about a rotary table on which the brush blocks are carried in an angularly spaced relation. The brush is completed during substantially one revolution of the table so that the finished brush comes off the table at approximately th same place that the brush block was originally positioned upon the table,

Adjustable holders for the brush blocks arearranged substantially tangentially of the rotary table and are pivoted near one end for sliding pivotal movement on the table within defined limits. The pivotal movement of a brush block in one direction is accomplished by sprin means acting on the brush block holder and movement in an opposite direction by stationary means having a follower portion engageable with a corresponding cam portion on the brush block holder. The follower portion is substantially in a ertical plane which includes the operating portion of an operating unit and acts on the cam portion, as the brush block is moved past the operating portion by the rotating table, to continuously position the brush block relative to the table and operating portion to provide for a series of like operations being performed on the brush block along a predetermined path. Thus for example in toothbrushes, the rows of bristles may be arranged in parallel alignment longitudinally over the brush portion of the brush, or such rows of bristles may be straight but inclined at an angle relative to each other. It is readily apparent, of course, that with the brush block in a fixed position on a rotating table, the rows of bristles would be of a substantially arcuate shape because of the arcuate path defined by the brush block as it travels by an operating unit on the rotating table. In other words, the arcuate path will be of a shape corresponding substantially to the peripheral contour of the rotating table. To accomplish an operation of the operating units in a linear path on the brush block'adjustable means are provided for continuously positioning the brush block, as it passes an operating unit, relative to the rotating table and operating unit. The adjustable means are adapted to move the brush block for operations thereon in parallel straight lines, or in straight lines inclined relative to each other.

As previously mentioned, considerable difficulty is encountered in brush making machines using straight anchors, in positively assuring the insertion of the anchors lengthwise into the brush block. In this invention anchor carrying fingers, which are also included in the anchor forming mechanism of the machine, are adapted for co operative action with a pair of jaws for inserting the anchor in a brush block, so as to position the anchor lengthwise between the closing portions of the anchor inserting jaws and in a plane substantially normal to such closing portions, with the anchor ends in a position to be positively located within guiding grooves in the jaws. The anchor is retained in this position by the anchor carrying means until the jaws are closed on the anchor. The anchor carrying means are then released or retracted from a carrying or holding position relative to the anchor to permit engagement of the anchor with an anchor driving rod for anchor inserting purposes.

The machine is illustrated in the drawings for making a brush having a pair of straight rows of bristles extended longitudinally of the brush, but inclined relative to each other, this arrangement of the rows being common in toothbrushes. It is to be understood, of course, that the machine is not limited alone to the making of toothbrushes and may be used in the making of brushes having straight parallel rows, or a single straight row, such as an eyebrow brush, or for making a brush havin one or more rows of shapes other than linear.

As shown in Fig. l of the drawings, a brush block or unworked handle 20 is positioned in a holder 2| carried on a rotary table 22 which is rotated in a counterclockwise direction as indicated by the arrow in Fig. 1. The holders 2| are angularly spaced in a circle about the table and near the outer periphery thereof. A brush block 20 is positioned within a corresponding holder when such holder is in the position indicated in Fig. 1 at A, and is arranged within the holder so as to extend longitudinally in a direction which is substantially tangential to the table 22. When the brush block is in the position indicated at A locking means 23, operatively associated with a each holder 2! for releasably locking a block in a holder. is automatically held in a released position by a stationary cam 24, carried on the table axis means 6| to permit thefree removal of a finished brush and the insertion of'a new block within the holder. The locking means 25 is held in a released position for a movement of the block from its position at A to a position indicated at B. On leaving the position B the block is locked in a fixed position within a corresponding holder 2| so as to be firmly held while the ineifective to release stationary blades 8 operatively associated with various operations providing for a completed' brush are performed ,on the block. At the position C the block is operated on by a drill unit, indicated generally as 26, which drills one row of holes 26 in the brush block for receiving bristle tufts. As illustrated, the machine is adapted to provide a brush having two rows of bristles, with each row being comprised of six tufts. Since each tuft requires a corresponding drill hole, means are provided to rotate the table such that the brush block is positioned in six positions relative to the drill unit 26 to provide for the drilling of the six holes.

When the brush and holder assembly are rotated to a position shown at D,'the brush is operated on by a tuft inserting and anchor wedging unit 21, which inserts tufts in the row of holes made by the drill 26. As seen in Fig. 9 this unit includes an anchor driving means 29 and a tuft and anchor carrying jaw means 29 adapted to have a bristle tuft presented thereto by a picker member 3|. An anchor is carried to the jaw means 29 by a combination anchor form ing and carrying means 32 (Fig. 6). The tuft inserting and anchor wedging unit 27 operates to insert and secure a tuft within the corresponding holes in the row so that the table is also rotated to six operating positions relative to this unit. A brush block 20 is positioned in an operating position relative to the drill 26 concurrently with the positioning of a drilled brush block at the tuft inserting unit 21. Rotation of the tables at six operating positions thus provides for the concurrent operations of drilling and tuft inserting in corresponding brush blocks.

After the bristles are secured in the row 25 the brush block is moved to a position at E where it is operated on by a second drill unit 33, similar to the drill 26, for drilling a second row of holes 90 in the brush block. On completion of this second drilling operation the brush block is moved to a position F to be operated on by a second tuft inserting an anchor wedging unit 34, similar to the unit 21, which inserts and anchors the tufts in the row of holes 30, It is to be understood, of course, that both of the drilling operations andthe tuft inserting and anchor wedging operations are performed simultaneously, but on different brush blocks, so that the making'of the brush is a continuous operation. On completion of the drillin and tuft inserting operations the brush block is moved substantially to a position G where the bristles in the rows 25 and 30 are combed by a combing mechanism indicated generally as 36. The comb 36 includes a pivoted combing plate 31 which is pivotally reciprocated in an arc transversely of the bristle tufts in the rows 25 and 30. When the bristles are properly combed and cleaned the brush block is moved to the position indicated at H, where it is operated on by a trimmer mechanism 38. The cam portion 24a, radially spaced from a block 20 at the position H serves merely to guide the follower portion 4| of the locking means 23 into an engaging position with the cam portion 24b and is a reciprocating blade R, with the row of bristles being passed in a direction longitudinally between the stationary blades. As the block leaves the trimmer mechanism 98 the follower portion 4| of the locking means 23 is engaged by the stationary cam portion 24b to release the completed brush for removal at the position A. It is seen, therefore, that the locking means 23 is retained in a released position substantially between the positions A and B and further that all of the operations on the brush block 29 to produce a completed brush are accomplished in something less than one complete revolution of the rotary table 22. l

The locking means 22, shown in detail in Fig. 4, includes a locking bar 39 movably supported for movement in a direction substantially radially of the table 22 and transversely of a corresponding block holder 2|. The rod 39 is of a substantially L-shape with the short leg or follower portion 4| extended upwardly, as viewed in Fig. 4, for engaging the cam or lip portion 42 on the cam means 24. The long leg of the rod 39 is pivotally connected at portions 43 and 44 with a corresponding link member 46 and 41, which link members in turn are pivotally connected with the table 22. This pivotal connection of the looking rod 99 with the table 22 permits movement of the rod both transversely and upwardly relative to the block holder 2|. The free end oi the locking rod 39 extends at least partially over a cavity 46 in the holder 2| for receiving a brush block 29, With the brush block 20 in the cavity 48, its top surface projects slightly above the top level or the holder 2| for frictional engagement with the locking rod 39. The rod 39 is moved into a locking position by a spring 49 connected at one end to the pivotal connection of the rod portion 43 and at its opposite end to the pivotal connection of the leg 41 with the table 22. Movement of the rod 39 out of a locking position relative to the holder 20 is accomplished by the cam means 24 in response to the rotation of the table 22 relative to the cam means. The hinged or pivoted connection of the rod 39 with the table 22 provides for a positive locking of the block 20 in a corresponding holder 2| regardless of any slight differences in the thickness of the brush handles being worked on. This pivoted connection also prevents any loose bristles which might fall on the table 22 from interfering with a free movement of the locking bar 39.

The cam means 24 is fixed on a stationary axis means 5| (Fig. 1) upon which the table 22 is freely rotatable. The table 22 includes two sections 52 and 53, which are suitably connected for concurrent rotation, with the complete table assembly 22 being slidably supported for rotation on a base portion (not shown) for the machine, which is located below the table section 53. In order to rotate the block 2| from one operating unit to a next related operating unit and successively relative to the same operating unit the section 52 is formed on its peripheral surface with angularly spaced ratchet or rack portions 54, and

the periphery of section 53 with angularly spaced notches 56. Although the sections 52 and 53 are illustrated as being separate it is to be understood that these two parts can be integrally constructed. Each ratchet portion has a series or set of six teeth. As previously mentioned the brush with which this invention is illustrated is comprised of the locking means 22. The

or hole in the brush being made.

two rows of bristles 25 and 20' with each row including six tufts. There is thus a tooth in each ratchet portion -54 which corresponds to a tuft The teeth in each tooth set or ratchet portion 54, on the section 52,- are engageable with a pawl or dog member 51 pivotally carried on a crank arm 56 having one end pivotally supported on the table axis means The opposite end of the crank arm 58 is pivotally connected to one end of a connecting for the table 22, ten of which are indicated in Fig. 1. These notches are selectively engageable with a pawl or dog 62 pivoted on a rocker arm 63. which is pivotally supported at one end on the axis means 5| and pivotally connected at its 0D- posite end with a connecting rod 64 adapted to drive the arm 63 in a predetermined sequence relative to the arm 56.

In the operation of the machine the rotation of the table 22 corresponding to one tooth space in a tooth set 54 advances the table in a counterclockwise direction a distance adapted-to provide for the drilling of another hole in the brush block or the insertion of another tuft in a corresponding hole, it being previously explained that the op eration of the machine is continuous with the drilling and inserting operations performed conrod 6| which is'connected to a suitable driving currently on different brush blocks. The pawl the pawl 51. On the sixth stroke of the pawl 51 and the corresponding sixth stroke of the pawl 62 the pawl 52 moves into engagement with the notch 56 corresponding to each brush station and advances the table to the next brush station. It is seen, therefore, that the pawl 51 moves the table only a fractional part of the distance which the table is moved by the pawl 62.

For the large table movement accomplished by the pawl 62 some difliculty might be encountered in stopping the table 22 at a position such that the teeth 54 are correctly located with reference to a position of the brush block 20 providing for the performance of a series of like operations thereon. To assist in the stopping of the table at the desired position, brake linings (not shown) may be provided between the table 22 and the base portion upon which it is supported.

As explained above, with the holders 2| in a fixed position on the rotary table 22, the brush blocks 20 will be moved in an arcuate path relative to an operating unit, which path would determine the shape of the bristle row in the brush. In order to provide for the bristles being arranged in a pair of straight rows inclined relative to each other, while the block 2|! is continuously rotated on the table 22 to successive operating positions, a holder 2| is adjustably movable for sliding movement relative to the table by means now to be described.

Each holder 2| is of a substantially rectangular form and is extended longitudinally in a direction substantially tangential to the periphery of the table 22. The cavity 48 in each holder 2| extends longitudinally of a, corresponding holder 2| s to in turn provide for the positioning of the handle 20 being worked on in a direction substantially tangential to the periphery of the. table 22 (Figs.

2 and 3) Each holder at its end 63, at which the handle portion of the block 2| is arranged, is pivoted on a pin 64 carried on the table 22. The pivotal movement of the opposite end" of the holder 2| is defined by a Pin 66 on the table 22 which is slidably received in an elongated open,- ing or cavity 61 formed in the holder. The holder end 64 is moved in a direction toward the periphery of the table 22 by springs 65 arranged-in compression between the holders 2| 'and stop portions ID on the table 22 as is illustrated only for the brush block 2| at the position C in Fig. 1. A pivotal movement of the holder end 64 in mopposite direction, or inwardly toward the center of the table 22, is accomplished by a stationary follower means 58, carried on the machine frame adjacent the table 22, which engages a corresponding cam surface or portion 56 formed on the holder 2| adjacent the holder end 64.

Referring to Figs. 3, 4, and 5, the adjustable stationary means 66 is illustrated in an operating position with the brush block 2| when such a block is at the position C .to be operated on by the drill 26. The cam surface 69 is formed near the top of the holder 2|, as viewed in Fig. 4, and to the outside thereof. This surface 69 is parallel with a linear path on the brush block 20 corresponding to the row 25 to be formed, as is clearly shown in Fig. 3. The follower portion 15 of the stationary means 66 for engaging the cam surface 69 is adjustable in a direction radially of the table 22 and located in a vertical plane which also includes the operating portion or drill H of the drill unit 26 (Fig. 5). successively moved from one-operating position to a next operating position relative to the drill II, the row'25 follows a linear path below the drill H by virtue of the holder end 64 being pivotally movable to always ride against the follower portion 15 so that the distance between the point of engagement of the follower portion 15 with the cam surface 69 and the drill ii is always equal. The drilling of each hole in the row 25, therefore, takes place in a path on the block 20 parallel to the cam surface 69, At the position D (Fig. 1) where the tuft is anchored in the holes in the row 25 there is a second stationary means 68 for engaging the cam surface 69 to position the row 25 for linear travel'beneath the tuft and anchor inserting unit 21.

In the drilling and tufting of the second row 30, which is inclined relative to the row 25, there is formed at the end 64 of the brush holder 2| and below the cam surface 69 a second cam surface 12 (Figs. 1, 2, and 4) the surface of which is parallel to the row 3|]. The cam surface 72 is associated with a stationary means 13, similar in construction to the stationary means 68, which operates in all respects relative to the cam 12 similar to the operation of the stationary means 68 and cam 69. A further description of the stationary means 13 and cam 12 is, therefore, believed to be unnecessary.

In the movement of a block holder 2| from one operating position to a next related operating unit, the end 64 of the brush block is moved by a corresponding spring 65 to an outer position defined by the engagement of the pin 66 with the end 60 of the slot 61 (Figs. 2 and 3). On the holder 2| reaching an operating position the engagement of a stationary means with a corresponding cam surface moves the holder end 64 inwardly against As the block 20 is amazes the spring 85, so that the spring 88, at each operating position, acts to positively maintain the engagement between a stationary means .and a corresponding cam surface. Although the adjustment of the block 2| has been described above with respect to the forming of two straight rows 25 and 38 which are inclined relative to each other, it is apparent that straight rows 25 and 38 inclined reversely'relative to each other as compared to their inclination in Figs. 2 and 3, or straight rows parallel to each other may be readily formed by merely changing the slope of the cam surfaces on the holder 2| to conform to the desired row arrangement. Although during the adjustment of a brush holder 2| by a stationary means 88 or 13 movement thereof takes place relative to the locking bar 38, the block 28 is always retained fixed relative to the holder by virtue of the sliding and pivotal movement of the locking rod 38 provided by its pivoted connection with the table 22, and the action of the spring 48 to always retain the locking rod 39 in frictional engagement with the block 28. A simple means is thus provided for forming straight rows of bristlm in a brush block which is carried on a continuously rotatable table to related operating units to complete the brush.

The drill units 26 and 83 are of a like construction and of a usual type, with each drill unit being associated with a suitable driving mechanism (not shown) operable to lower and raise a drill at the proper times relative to the movement of the brush block thereunder. A further description of the drill is, therefore, thought to be unnecessary. The tuft and anchor inserting units 21 and 34 are also of a like construction. Only one unit 21 will, therefore, be referred to in detail in the following description.

As previousl mentioned, considerable difiiculty has been encountered in the prior art brush mak ing machines using an anchor of straight form for retaining a corresponding bristle tuft in a brush block, in providing for the positive insertion of the anchor lengthwise into the brush block. This difiiculty has been completely eliminated in the present invention by a combination anchor forming and carrying means 32 adapted for coperative action with the jaw means 29 of the unit 21 to always position the anchor within the jaw means to assure its being properly driven into a brush block by an anchor driving rod |35. An anchor I4 for securing a tuft 16 within the brush block 28 is shown in Figs. 7 and 8. This anchor is essentially a, short, straight length of a thin piece of hard wire which, although shown as round, may be of any other configuration. The wire 11 (Fig. 6) from which the anchors 14 are formed is fed into the machine from a suitable supply source (not shown) over timed feeding rollers I8 and 19 into a stationary die member 8| having a wire receiving aperture therein. The

' wire 11 is guided in its passage from the supply 8 4, as viewed in'Flg. 6, having a notch for receiving the wire Tl from the block 8|.

The fingers 83 and 84 are pivotally supported intermediate their ends on corresponding axis means 88 supported on a mounting plate 81 and are held against the mounting plate by a retaining plate 88. The end 88 01' the finger 83 is con nected to one end of a tension spring 9|, the opposite end of which is connected to the mounting plate 81. The spring acts to rotate the finger 83 in a clockwise direction, as viewed in Fig. 6, and into engagement with the finger 84 to in turn rotate such finger in a clockwise direction-and against a stop member 82 on the mounting plate -8'l. By virtue of this stop the fingers 83 and 84 are retained in a closed position by the spring 9|. The mounting plate 81 is carried on a floating or pivotally movable portion 33 rotatably supported in a boss portion 84 formed at the lower end of a long upright pivoted arm 88'which is pivoted to a portion 81 of the machine frame on a shaft 88. The pivotal movement of the mounting plate 81 in one direction is limited by a stop member I88 fixed on the boss portion 94 and in an opposit direction by the engagement of the plate 81 directly with the portion. The mounting plate 81 is yieldably retained against the stop portion I88 by a spring 83 arranged in compression between the boss portion 84 and the retaining plate 81. When the closing ends of the fingers 83 and 84 are adjacent the stationary block 8|, the action of the spring 9! acts to retain these finger portions in sliding engagement against the block 8|. In other words, the stop I88 limits the pivotal movement of the retaining plate 81 in a direction toward the die 8| when the fingers 83 and 84 are removed from the die 8|.

As previously noted, the pivotal movement of the fingers 83 and 84 in a clockwise direction, as viewed in Fig. 6, by the spring 8| is limited by the stop 92. However, the fingers are capable of pivotal movement together in an opposite or counterclockwise direction on pressing upwardly of the finger .84 against thefinger 83. Thus in the forming of an anchor 14 from the wire TI, with the wire extended between the fingers 83 and 84, a driving arm IN is moved upwardly against the finger 84 to move the fingers 83 and 84 in a counterclockwise direction or upwardly relative to the die member 8|. This movement of the fingers provides a cutting action between the finger 84 and the die member 8| to cut the wire 11 and leave an anchor 14 between the fingers 83 and 84. The length of the anchor 14 is determined by the timed movement of the rollers 18 and 19. In other words, a partial relative rotation between the rollers 18 and 19 moves the wire 71 a predetermined distance through the 'die 8| for cutting into an anchor. Thereafter the fingers 88 and 84 move to the wire for cutting the wire and provide the anchor 14. In accomplishing this rotation of the rollers 18 and 13 the roller 18 is mounted on a shaft I82 which also carries a ratchet wheel I83. The ratchet |83 is associated with a pawl |84 pivoted on an arm I88 which is rotatably supported at one end on the shaft I82 and is pivotally connected at its oppositeend to a crank I81 eccentrlcally mounted on a driving shaft 88. Thus when the shaft |88 is rotated through a complete revolution the roller 18 is rotated through a predetermined angular distance corresponding to the desired length of the anchor 14. The roller 18 is essentially an idler roller carried at one end of a pivoted armi'88, the opposite end of which is underthe tension of a spring I to continuously urge the roller 13 against the roller 18. The wire 11 is thus frictionally engaged between the rollers "and 19, with the positive moving of the wire 11 between the rollers being facilitated by knurling the periph-- eral surface ofthe roller 18.

a stationary jaw I28.

11 The driving arm III forms one arm of a bell crank I I2 whichisplvoted at H3. The free 'end of the other arm II4 of the bell crank II2 has a cam dollower III associated with a cam II'8 mounted on the driving shaft I88. The cam fol- ,lower is maintained in a following relation with the cam III by a spring I I1 connected to the arm IM and to a portion of the machine frame. It is seen, therefore, that the driving arm IIII is driven against the finger 84 by the cam H8 and is returned to a rest or idle position out of engagement with the finger'84 by the spring II1.

By virtue of the closed ends of the fingers 83 and 84 being slidable against the stationary guiding block 8| during an anchor cutting operation and the cutting of the anchor 14 by the finger 94 the formed anchor 14 within the fingers 83 and 84 has one end II8 terminating at the side surface of the fingers adjacent the block 8i. and an opposite end I41 extended outwardly from the fingers (Fig. 7). The moving of the fingers 93 and 84 away from the stationary block 8i and to a position for presenting the anchor 14 to the jaw means 29 is accomplished by means including a roller II9 rotatably mounted on a shaft I29 carried in the boss portion 94 of the pivoted arm 88. The roller I I9 is operatively associated with a cam I2I mounted on the drive shaft I88 and is held in a following relation with the cam I2I by spring members I22 arranged in compression between the pivoted arm 98 and the machine frame portion 81. The pivotal movement of the arm 99 by the springs I22 is limited by an adjustable stop I25 on the frame 91 to retain the follower H9 away from the cam I2I during the feeding and cutting operations of the wire 11. On completion of these operations the follower H9 is acted on by the high surface of the cam Hi to move the fingers 83 and with the anchor 14 therebetween toward the jaw means 29 and to the position indicated in Fig. '1.

The jaw means 28 includes a block member I23 (Figs. 8 and9) which is slidably supported for movement in a vertical direction in cooperating way members I24 and I28 mounted on the machine frame and carries a movable jaw I21 and The jaw I28 is fixed on the reciprocating block I23 and is adapted for closing engagement with the movable jaw I21 which is pivotally supported on the sliding block I23 at I29. The jaw members I21 and I28 are retained on the sliding block I23 by straps I3I and I32 with the pivotal movement of the jaw I21 being guided and defined by the reception of a pin I33 carried on the block I23 in a slot I34 in the jaw I21. Pivotal movement of the jaw I21 into a closing position with the jaw I28 is accomplished by a spring I38 acting at the upper end of the jaw I21, -as viewed in Figs. 7 and 8. which spring releasablyretains the jaws in such closing position. In closing position the closing portions of the, jaws I21 and I28 have their inner faces in substantial parallel alignment. Each inner jaw face has a corresponding longitudinal groove I31 and I38 for guidably retaining the ends of the anchor 14. Since the movable jaw I21 is spread away from the jaw I28, as is shown in Fig. '1, to receive the anchor 14 therebetween the inner surface of the closing portion of the jaw I28 is always in a substantially vertical plane.

The jaws I21 and I29 are normally spaced apart to receive therebetween a driver I 39 for the anchor 14. The driver I39 is formed as a part of the anchor driving means 29 which further includes a block I for carrying the driver I28 12 slidable in the ways I24 and I28 but movable relative to the block I23 (Fig. 9). The driver I39 Derated through a connecting rod I42 pivoted to the block I, while the jaws I21 and I28 are operated through a corresponding connecting rod I43 pivoted to the block I23, the rods I42 and I43 being actuated through suitable m hanism (not shown) to accomplish a predetermined rielative movement between the driver I39 and the jaws I21 and I23 during a tuft and anchor inserting operation. In the operation of the driver I39 its lower end I48 engages the upper surface of the anchor 14, the ends of which are guidably retained or supported in the grooves I38 and I39 of the jaws I21 and I28, respectively. In one embodiment of the invention the anchor 14 has a diameter of about .018 inches and is about V; of an inch long. Because of the small diameter of the anchor the driver I39 has a corresponding thickness of about .018 inch and a width of about 54; of an inch so as to be of a narrow, thin, ribbon form. To assure a positive engagement of the driver with the anchor at all times of operation, the stationary jaw I29 above the closing portion thereof is integrally formed with a projecting or guide portion I44 (Fig. 8) extended toward the movable jaw I 21 which is formed with a corresponding shoulder portion I46 to guidably receive the projection I44 when the jaws are in a closing position. The projection is formed with slots or grooves for slidably receiving the driver I39. with the vertical movement of the driver being such that it is continuously guided in a vertical path within the projection I44. The groove I31 in the closing portion of the jaw I28 is continuous with one of the guiding grooves in the projection I44 so that the driver is continuously-guided relative to the jaw I28, and aligned for reception in the groove I38 in the movable jaw I21 when the jaws are in a closing position. The driver is thus always capable of engaging the anchor 14 so that any possibility of the driver not riding in the grooves I31 and I38 during an anchor inserting operation, as sometimes occurs when the driver is retracted from the jaws at some point in its movement, is positively eliminated.

To assure the anchor 14 always being driven lengthwise into a brush block 28 it is necessary that, prior to the anchor driving operation, it be positioned lengthwise between the jaws I21 and I 28 in a plane substantially normal to the inner faces of the jaw closingportions, or to the grooves l31and I38 in such faces. with the ends of the anchor in corresponding grooves. Where the anchor is between the jaws in a, tilted or inclined position relative to this plane, the driver I39, even though engageabie with the upper side of the anchor, acts to further tilt the anchor rather than to properly straighten or position it for insertion lengthwise into the block 28. As a result of this action the anchor oftentimes is inserted endwise into the block so that it fails entirely to secure'a corresponding tuft in the 13 the inner face of the closing portionof the stationary Jaw I28 when the jaws are in their open position as shown in Fig. 7. The ends of the fingers 88 and 84 are tapered to facilitate the fingers being inserted between the Jaws I21 and I28 and by virtue of the pivotal movement of the retaining plate 81 relative to the pivot arm 98 the fingers 88 and 84 are slidably moved against the stationary jaw I28 to a position at which the anchor end H8 is directly opposite the groove I 31 in the stationary Jaw I28. This position of the anchor end H8 is determined by the movement of the fingers 88 and 84 by the cam I2I. Further the jaws I21 and I28 are arranged in a plane substantially normal to the plane of pivotal movement of the fingers 88 and 84 so that the anchor 14 is positioned in a plane substantially normal to the plane of the inner faces of the closing portions of the laws I 21 and I28 concurrently with the location of the anchor end II8 immediately at the groove I81. The end I41 of the anchor 14 is thus in turn located opposite the groove I88 in the movable jaw I21. With the anchor 14 retained in this position by the fingers 83 and 84 the movable jaw I21 is moved into a closing position with the stationary Jaw I28 to receive the anchor 14 for guidable support within the corresponding grooves I81 and I38, as is shown in Fig. 8, while extended lengthwise between the jaws is a plane substantially normal to the inner faces of the jaw closing portions. After the jaws I21 and I28 have been closed on the anchor 14 the fingers 88 and 84 are moved out of an anchor holding or carrying position by the cam I2I, the end of the fingers 88 and 84 being Pulled away from the anchor 14 by the anchor spreading the flngem apart against the action of the spring 9|.

Since any vertical movement of the jaw means 29 and in turn of the jaws I21 and I28 during the time the anchor 14 is not held by the fingers 88 and 84 might result in tilting the anchor between the .Iaws, the jaw means is held against any vertical movement until after the jaws have closed on the anchor. Movement of the jaw I21, while the jaw means is stationary is made by a cam portion I48 carried on a shaft I49 rotatably supported in a portion I5I of the machine frame including the ways I24 and I28. The cam I48 (Figs. 8 and 9) is suitably keyed to the shaft I49 which also carries thereon in a keyed relation an arm I52 pivotally connected with a connecting rod I58 having a follower I54 at its free end for engaging a cam I58 mounted on a driven shaft I51 which is also common to the picker mechanism of the machine, and which will be later described. The cam I48 is engageable with a corresponding projection I58 at the top of the movable jaw I21, as viewed in Figs. 8 and 9, and is operated by the cam I58 and the follower I54 to move the jaw I21 relative to the jaw I28 in a predetermined sequence relative to the moving of the fingers 83 and 84 by the cam I 2| In the picker mechanism shown in Fig. 9, the bristles I59 used in making the brushes are stored in a magazine or rack I8I arranged in a substantially upright or vertical position, the bristles being positioned in a longitudinal direction and extending from front to back as viewed in Fig. 9. A weighted plate I82 on the top of the bristles in the rack I8I maintains a certain amount of pressure on the bristles to feed them through the rack and toward the pivoted picker member 3|.

The picker member 8| has a substantially arcu- 14' ate portion I88 which is pivotally movable across the lower end of the bristle magazine, as viewed in Fig. 9, and has a radial arm I84 carried on a rotatable shaft I 88. The outer peripheral edge of the arcuate portion I88 maintains the bristles I59 in the rack I H as the picker member'is rotated across thelower end thereof. This peripheral edg has a notch I 81 which is of a size to remove from the face of the bristles at the lower end of the storage rack I8I a quantity of bristles in an amount to produce a tuft 18 of a desired size for the brush. The picker member 8I is shown in Fig. 9 at one end of its operating stroke with a tuft 18 in the notch I81 at a position to be received between the jaws I21 and I28 for insertion with the anchor 14 into the brush block 28. The picker member is pivotally movable in a plane which is substantially parallel and adiacent to the plane of vertical movement of the jaw means 29 to permit free relative movement between these parts. The shoulder or ofiset portion I88 near one end of the arcuate portion I88 acts to pack down the bristles in the storage rack.

It is important, of course, that thebristles at the lower end of the magazine I8I be in a condition such that a substantially uniform quantity of bristles is received within the notch I81 on each passage thereof across the magazine. Althoughthe upright position of the magazine in cooperation with the weighted plat I82 tends -to pack the bristles toward the lower end, this packing is usually inadequate, particularly when speeds. As previously mentioned, the shoulder portion I88 on the picker assists in this packing function. To further pack the bristles at the lower end of the magazine I8I there is provided a packer means comprised of a packer arm I12 and an operating arm I13 fixed with respect to each other and supported for pivotal movement on a stationary axis means I14. The lower end of the packer arm I12, as viewed in Fig. v9, is formed with two spaced projecting portions which on pivotal movement of the arm I12 towards the magazine I8I acts to pack the bristles at the lower end of the magazine in a direction toward the picker member 8|. The arm I12 is driven by means-including a .connecting rod I18 connected at one end to the lower end of the arm I18 and pivotally connected at its opposite end to the leg I11 of a bell crank I18. The bell crank I 18 is pivotally supported at I19 'and has the leg I 8I thereof pivoted to a sleeve member I82 slidable on a shank I88 formed as part of an eccen trio I84 supported on the drive shaft I51. The eccentric I 84, sleeve I82, and bell crank I18 are all part of the driving mechanism which provides a delayed or lost motion action for properly timing the operation of-the pa cker arm I12 with reference to the operation of the picker member 8|, so that the packer arm I12 is moved toward the picker member 8I as the notch I 81 is moved in a counterclockwise direction, as viewed in Fig. 9 across the lower end of the bristle magazine I 8I.

A pivotal movement of the picker member 8| across the lower end of the rack I8l is accomplished by suitable operating mechanism (not shown) associated with the shaft I88. In the operation of the picker member 3| the notch I 81, when moved in a counterclockwise direction, as viewed in Fig. 9, across the lower end of the brietle rack I 8| cuts or removes a measured quantity of bristles from the magazine. When the notch passes from the bristle magazine the bristles are carry the tuft from the buffer plate to a position for engagement by the jaw means 28. This carrying of the tuft 18 is accomplished by a tumbler unit In which cooperates with the buffer plate I88 to retain the tuft 18 within the notch I 81 at all times of its transfer from the bristle rack I8I to th jaw means 28.

The tumbler "I is located below the picker member 8| and above the holder 2I for a brush block 2|! (Fig. 9) and is mounted on a shaft I88 for pivotal movement in and out of vertical alignment with the jaw means 28. As shown in Fig. 9 the tumbler is in vertical alignment with the jaw means 28 and in this position functions during an anchor and tuft inserting operation, to double up the bristle tuft 18 and to guide the doubled tuft all the way down to a position in the brush block 28. The tumbler "I is pivotally moved by a crank arm I81 rigidly mounted on the tumbler shaft I88 and pivotally connected at its free end to one end of a connecting rod I88. The other end of the rod I88 is pivotally connected at I88 to the arm I11 of the bell crank I18. The driving mechanism for the packer arm I12 is thus common to the driving mechanism for the tumbler ill with the lost motion in this driving mechanism being such as to properly time the movement of the tumbler with respect to the jaw means 28 and the picker member 8|. Thus as shown in Fig. 9, the tumbler I1I is in'vertical alignment with the jaw means 28 concurrently with the location of the tuft 18 at a position to be engaged by the jaws I21 and I28 of the jaw means 28.

With the tumbler I1I in vertical alignment with the jaw means 28. the upper edge thereof is used to retain the tuft 18 within the notch I81 after the notch is moved away from the buffer I88. That is, the extreme end I 8I of the buffer member I88 stops short of the center of the jaw means 28 so as not to interfere with the operation of the jaws I21 and I28 in engaging the tuft 18 and carrying the same to the brush block 28. flowever, because of the timed relation of the tumbler in relative to the jaw means and picker member, the upper edge of the tumbler I1I is in substantial alignment with the arcuate surface of the buffer member I88 at the time the notch I81 passes oil the buffer I88 so that the tuft 18 is continuously retained within the notch I81 for transfer from the rack I8I into the path of movement of the jaw means 28 and between the jaws I21 and I 28. Thus at the jaw means 28 the tuft 18 is retained in the notch I81 by the upper surface of the tumbler I1I. It is seen, therefore, that the tumbler I1I performs its usual functions in retaining inserted bristle tufts free of the hole in which a new tuft is to be inserted, and a bristle doubled until the time it is inserted in the brush block 28, and further acts to retain the tuft 18 within the picker member 8| until it is engaged by the jaw means 28.

From the above description it is seen that both the anchor 14 and bristle tuft 18 are presented to the jaws I21 and I28 for insertion together into 16 the brush block 28 by the driver I88. In Order for the jaws I21 and I28 to close on both the anchor and the tuft it is necessary that they be in their open-position, shown in Figs. 7 and 9, when the anchor and tuft are first presented therebetween. In the embodiment of the invention above referred to, the overall vertical movement of the jaw means 28 above the position shown in Figs. '7 and 9, at which the tuft is received between the jaws I21 and I28, is only about one quarter of an inch. In this one quarter inch overall movement the jaws I21 and I28 may be spread apart by the cam I48 acting on the movable jaw I21 either on the up-stroke of the jaws away from the tuft receiving position shown in Figs. 7 and 9, or on the down stroke of the jaws from a top or uppermost position toward a tuft-receiving position, or over both the up and down strokes of the jaws in the one quarter inch overall movement. The jaw carrying fingers 88 and 84 are operated to move between the jaws I21 and I28 after they are in an open position and into sliding engagement with the inner surface of the closing portion on the stationary jaw I28. This relative positicn of the anchor carrying fingers and the jaws I21 and I28 is retained until the laws are moved to their position shown in Figs. 7 and 9 for receiving the bristle tuft 18.

At this position of the jaws I21 and I28 the jaw means 28 is retained against vertical movement and the cam I48 is moved out of an engaging position with the projection I58 to permit the jaw I21 to close with the jaw I28, on both the anchor 14 and the bristle tuft 18. After the jaw I21 has closed .with the stationary jaw I28 the anchor holding fingers 83 and 84 are withdrawn from between the jaws and the jaw means 28 moved downwardly into the tumbler I1I concurrently with the operation of the driver I88 to insert the tuft 18 and anchor 14 in the brush block 28. It is seen, therefore, that the jaws I21 and I28 are retained against any vertical movement downwardly, while the jaw I21 is being closed on the anchor 14 and tuft 18, and that their downward movement is continued substantially concurrently with the retraction of the fingers 88 and 84 from the anchor 14. As a result the guiding of the fingers 83 and '84 on the inner face of the stationary jaw I28 to properly locate the anchor 14 for gripping between the Jaws I21 and I28 is positively retained by virtue of the anchor 14 be ins stationary relative to the law I28 during the closing of the jaws.

From a consideration of the above description and drawings it is seen thatthe invention provides a machine in which a brush block carried on a continuously rotating table to related operating units is automatically adjusted during the rotation of the table such that the completed brush is formed with straight rows of bristles. The in vention further provides means for assuring an anchor of straight form being driven lengthwise into the brush block to positively secure a corresponding bristle tuft. Although the machine has been particularly described with respect to making a brush in one continuous operation having a pair of straight rows thereon inclined relative to each other it is apparent that the means fOr adlusting the brush block holder 2I are adapted to provide, in conjunction with the brush holder, a row of bristles on the brush of any form. In those instances where the brush block is formed by a molding operation, during which operation the holes for receiving the bristles are simultaneously formed, the drills 28 and 33 may be eliminated acsaum l7 and one or more anchor and tuft inserting units used depending upon the number of rows of holes in the molded handle to be tufted.

Although the invention has been described with reference to a specific embodiment thereof it is to be understood that it is not to be so limited since modifications and changes can be made therein within the intended scope of this invention as defined by the appended claims.
