8 Claims.

Our present invention relates to brush making machines, and more particularly to an improved machine for assembling component parts of a brush into a complete unitary structure.

Our present machine is designed to eliminate to as great a degree as possible the manual assembling of the component parts making up a brush, and particularly a brush of the paint type. In carrying out our invention the handles of the brush are stored in a magazine from which they may be removed one by one and the brush end of a brush consisting of the tuft of fibers assembled within one end of a ferrule are also assembled in a magazine and from which the same may be fed one by one. In accord with our invention the feeding mechanisms for the handles and the brush units are arranged to operate in synchronism and therefore to simultaneously remove a handle and a brush unit from the magazines and feed the same into operative relation to each other in a device which is designed to forcibly insert the end of th handle in that end of the ferrule which is not occupied by the tuft of fibers constituting the brush.

A machine embodying our invention contemplates the use of a plurality of stations at each of which is arranged an operating mechanism for performing an essential operation on the brush in process of assembly. The stations may be any number that is desired, the number, however, depending on the number of operations to be performed. In a preferred showing of a machine embodying our invention there are, in addition to the station for assembling the handle an the brush unit, other stations, as a station for applying nails or other fastening means to one side of the brush, a station for printing any desired marking on one side of the brush, a station for turning the brush over through an angle of 180, a printing mechanism for performing a printing operation on the other side of the brush, a station for applying nails or other fastening means to the other side of th brush, a station at which the brush Or tuft unit is combed and formed, and a station in which is utilized mechanism for placing th completed brush in a collecting magazine.

All of the mechanisms at the various stations are operated in synchronism with each other,

for each cycle of operation of the machine.

A feature of our invention is a unitary combined structure for assembling brush elements into a unitary structure and in which a series of operations are successively performed on the brush elements.

A further feature of our invention is a unitary combined structure in which a plurality of operations are successively performed on brush elements to produce a unitary brush structure and in which such operations are successively performed by a series of independent instrumentalities.

A still further feature of our invention is an improved unitary combined structure for performing a series of operations on brush elements to produce unitary brush structures and in which all of the operations of the series are performed simultaneously, each operation being performed on a separate brush assembly.

A still further feature of our invention is an improved unitary combined structure in which operations are performed on both sides of a flat or oval brush assembly and in which instrumentalities are provided for rotating the brush assembly through an angle of at some point during the progress of the brush assembly from one operating instrumentality to another.

A further feature of our invention is a unitary combined structure in which a plurality of working instrumentalities are arranged in series relation, each performing its own operation, and in which the various instrumentalities are operated in synchronism with each other and with a brush assembly propelling mechanism for moving the brush assembly being operated upon from one working instrumentality of the series to another.

Other features of the invention will appear more clearly as the description of the invention progresses.

Referring to the drawings III designates in its entirety the framework of a machine composed essentially of end pedestals ii secured in spaced relation to each other by longitudinal bars is located adjacent the lower end thereof, on the top of which pedestals is mounted a platen or table II. Secured to the top of the platen or table 13 at one side thereof and in alignment with each other are pillow blocks l4, and in these pillow blocks is rotatably mounted a main drive shaft 15. The main drive shaft I! has attached thereto at one end a pulley l6 and by means of which the drive shaft 15 is rotated in the desired direction from any suitable source of power (not shown).

Adjacent the end of the platen or table i3 nearest the pulley IB, and on the under side of such platen or table are secured a pair of aligned pillow blocks II, (but one of which is shown) and in these aligned pillow blocks is rotatably mounted a shaft 18 and which, as clearly shown in Fig. 1, is located beneath and extends perpendicular to the main drive shaft [5. Secured to the under face of the platen or table II and on the under side thereof adjacent to the end remote from the pillow block I1 is a pair of pillow blocks ll, these pillow blocks being in alignment with each other. Rotatably mounted in these pillow blocks II is ashaft II which lies parallel to the shaft ll above described.

Secured to the shaft II and spaced apart from each other are two sprocket wheels 2! (but one of which is shown), and these sprocket wheels are respectively in alignment with similar sprocket wheels 22 secured to the shaft 20. Over the pairs of sprocket wheels 2| and 22 run endless sprocket chains 23, each of which constitutes a conveyor for moving respectively the handles and the brush ends of the brush to be assembled. Secured to the upper face of the platen or table II are tracks 24 for guiding the upper reaches of the sprocket chains 28 and for insuring that such upper reach of each sprocket chain runs in a straight line along and above the table II.

Secured to the sprocket chains is, at spaced intervals along the length thereof, are fingers as and 26 respectively, the fingers II being attached to one of the sprocket chains ll and the fingers 26 being attached to the other sprocket chain. The fingers 26 and 26 are different from each other, the fingers 26 being designed to enga e with the handles-for the brushes to move the same, while the fingers 26 are designed to engage with the brush end and move the same. Ob-

viously the sprocket chains II move in unison in the same direction and at the same speed.

Adjacent the end of the platen or table II in proximity to the pillow blocks II, and on the top of such table, is a, bearing standard I. in which is rotatabl mounted a shaft II. 5ecured to the shaft II is a helical pinion II which meshes with and is driven by a helical pinion ll secured to the main drive shaft I6. Secured to or formed integral with the shaft 2| is a hub 32 provided with a radially extending arm a which has formed 'therein a T-slot I4. Mounted for slidable adjustable engagement in the T-slot 34 is the head 35 of a stud l6, threaded adjacent its outer end to receive a nut 31.

On the stud 36 is arranged a bearing washer 38, and between the bearing washer 38 and the face of the radially extending arm 33 is placed a bearing bushing 39. By means of the nut 31, washer 38 and bushing 39 the stud 36 may be securely held in any desired position of the head 35 with respect to the T-slot 34.

Rotatably mounted on the bushing 39 is one end of a connecting rod 40. The connecting rod 4| has formed at its opposite end a rack 4| which meshes with and oscillates a pinion 42 formed integral with a housing 44. The rack H is held in engagement with the pinion 42 by a housing 43 which encloses the end of the connecting rod :6, and is in turn rotatably mounted on the shaft Formed integral with the pinion 42 and rotatable on the shaft 20 is an annular housing 44 in which is housed a clutch member so formed on a hub 46 secured to the shaft 2|. A cover plate 41 may be utilized to close the open end of the housing 44. The clutch member 46 is provided with a plurality of angular cut-outs "a, the larger length of which forms, with the periphery of the interior of the'housing 44, a tapered compartment, as clearly shown in Fig. 15. In each of the angular cut-outs 46a is housed a cylindrical clutch member ll.

With the above described construction, and referring to .15, it will be apparent that a movement of the rack ii in the direction of the arrow shown in such figure will result in rotating the housing 44 and consequently the cylindrical clutch members 48 will move to the highest part of the angular cut-outs 45a. Under these conditions no rotary movement will be imparted to the shaft 20. Conversely, when the rack 4| is moved in a direction opposite to that indicated by the arrow in said figure, the rotation of the housing 44 will result in the cylindrical clutch members 48 moving toward the narrowest part of the wedge-shaped chamber formed by the angular cut-outs 45a and the periphery of the interior of the housing 44, to thereby lock the clutch member 45 to the housing 44 and causing a rotary movement of the shaft in the opposite direction to the arrow shown in Fig. 15, or in the direction of the arrow shown in connection with shaft 20 in Fig. 14.

Because of the manner of connection of the crank 33 to the shaft 29 there is imparted an intermittent rotary movement to the shaft 20, which thereby results in imparting an intermittent movement of the upper reach of the sprocket chains 23. The extent of such intermittent movement may be controlled by adjusting the head 35 of the stud 36 in the T-slot 34. The adjustable intermittent movement of the sprocket chains 23 may be thus adjusted to conform with the spacing of the various stations along the length of the table I3.

In order to prevent retrograde rotary movement of the shaft 20, and therefore a retrograde longitudinal movement of the sprocket chains 23 we provide the following instrumentalities. One of the pillow blocks I9 has formed integral therewith a housing 49 in which is formed an annular chamber. In this chamber is rotatably mounted a clutch member 50, similar in construction to the clutch member 45, but having the cut-outs a therein oppositely arranged. The clutch member is secured to the shaft 20 in the usual manner. Fitting in the cut-outs 45a. of the clutch member 50 are cylindrical clutch members 48. The open end of the clutch housing 49 is closed by an annular cover plate 5|.

This mechanism is so arranged that as the rack 4| rotates the shaft 20 in the direction of the arrow shown in connection with such shaft 20 in Fig. 15, the cylindrical clutch members 48 in the housing 50 will be moved to the large end and thereby prevent retrograde rotary movement of the shaft 20.

Mounted on the table I3 between the upper reaches of the endless sprocket chains 23 is a table or slide over which the handles of the brushes are moved step-by-step by the endless sprocket chains. Also mounted on the table I3 and arranged parallel to the table or slide 50 is a second table or slide BI over which the brush units of the brushes are moved step-by-step by the endless sprocket chains 23. The tables or slides 60 and 6| extend throughout the whole length of the table I3, and are periodically interrupted wherever such interruption is necessary to provide a space for some mechanism for performing an operation or operations on the brush units. The tables or slides 60 and GI are of appropriate height above the table I3, though not necessarily of the same height, and such tables or slides at the exit end thereof curve downwardly as indicated by the reference character 2!, so as to assist in guiding the assembled brushes into a receiving device which transfers the completed brushes into a collecting mechanism.

Arranged along the length of the platen or table I3 and spaced apart from each other, and in such a manner as to be adjustable toward and from each other to vary the distance between them, are mechanisms for performing various operations on the component parts of the brushes. Such operations may be assembling the component parts into a unit brush; securing such component parts in position relative to each other; marking the component parts to designate the type and size of brush or any other information that may be desired; turning the component parts of the brush over through anydesired angle to bring any other desired portion thereof into operative relation with the assembling mechanism; brushing and treating the flbrous portion of the brush to size the brush, etc.

The above mechanisms are located on what we call stations, and at each station is an operating mechanism, and in the ordinary brush such mechanisms are as follows. An assembling mechanism for assembling the component parts of the brush into a unitary structure. marking station where the size of the brush being operated on is marked. A first nailing station where securing means is applied to rigidly hold the component parts of the brush in assembled relation. A first printing station wherein desired indicia is printed on one side of the assembled brushes. A turning mechanism for turning the assembled brush unit over to any desired angle to bring a face thereof into engagement with the succeeding mechanism, by means of which the printing is applied to the other face of the brush. There is then arranged a second nailing station where additional securing means is applied to the nailing station to hold them to the same in more firmly assembled position. There is then arranged a brushing station having mechanism for combing, brushing, and cutting, and forming the assemblage of bristles into the desired shape and form. Other mechanisms may be added if the necessity therefor arises.

The assembling station is designated at the right-hand side of Fig. 1, and the details of such assembling station are illustrated in Figs. 2, 3, 4 and 5, and referring to such figures, together with Fig. 1, there is shown a brush unit magazine 62 having a plurality of superimposed brush units 63 therein and with the bottommost brush unit 63 resting on the table or slide BI. There is also arranged a handle magazine 64 having a plurality of superimposed handles 65 therein, the bottommost handle of which rests on the table or slide 60. The brush units 63 and handles 65 are placed in their respective magazines manually, as usual.

Associated with the magazines 62 and 64 is a mechanism for assembling the brush units 63 and handles 65. This mechanism comprises the following instrumentalities. Beneath the table I3 and secured to the underface thereof, are aligned pillow blocks 66 in which is rotatably mounted a shaft 61. The shaft 61 is arranged parallel to the shaft I8, and, therefore, extends perpendicular to the line of movement of the upper reaches of the endless sprocket chains 23. Secured to'the shaft 61 adjacent to the pillow block it beneath the magazine 04 is a cam 00, such cam being provided with a can race On top of the table it and secured thereto by screws 10 is a slideway ll provided with a v-shaped groove I2 therein, and which extends longitudinally of the member Ii and parallel to the shaft .1. Secured to the top face of the table II are aligned bearings 13 in which is slidably mounted a shaft 14. Secured to the shalt l4 and adjustable thereon is a member ll having formed integral therewith a V-shaped member It which slides in the V-shaped groove 12 of the member II and is also provided with an upwardly extending arm'll provided with an enlargement It at the top thereof. The enlargement II is bored to receive as a sliding fit a shaft ll, such shaft being secured in adjusted position by the bolt ll. Secured to. or formed integral with one end of the shaft It, is a V- shaped member II which is adapted to engage with the end of a handle ll. Also secured to the member II and extending downwardly therefrom is a member I! provided at its lower end giving a reciprocating motion to the member Ii.

This motion is of suillcient amplitude to move the end of the brush handle II from the full line position shown in Fig. 5 to the dot-and-dash line position shown in such figure. This movement is sumcient to insure that the other end of the handle I! will be seated in the ferrule '4 of the brush unit 63.

Secured to the shaft 81 and spaced apart from each other are the cams l5 and I. Secured to the table 13 in any desired manner is a member 81 which has secured thereto by pin II a shaft 88. One end of such shaft 89 protrudes beyond the limits of the member 81 and has rotatably mounted thereon the levers 9i and 92. The levers 9i and 92 are similar in construction and constitute mechanism for firmly gripping the ferrule 84 of a brush unit 63 against movement during the period when the end of the handle 65 is being forced into the ferrule '4 of the brush unit by the mechanism above described.

The lever 9! is provided on its lower end with a rotatably mounted cam roller 83 which engages with the cam surface of the cam 85. The lower end of the lever 82 has rotatably mounted thereon a cam roller 94 which engages with the cam surface of the cam 86. The lower ends of the levers II and 82 are constantly urged toward each other by means of a coil spring 95, such spring also tending to keep the cam rollers 93 and 94 in engagement with their respective cams. The upper end of the lever Si is provided with a V-shaped jaw 96, and similarly the upper end of the lever 92 is provided with a V-shaped Jaw 81. These jaws are adapted to engage with and grip the ferrule 84 of the brush unit 63 and hold the brush unit relatively stationary during the brush and handle assembling operation.

The shaft 61 in its rotating movement has the engagement with the ferrule 14 of the brush unit 08, and into position where the fingers 2| It on the endless conveyor chains 28 and referring to such figures, there is shown an arm or pedestal ill secured to the top of the table II by bolts ill, said arm being provided with a curved magazine or magazines I for holding and positioning in proper order the plurality of staples I04. In alignment with the arm or pedestal ill and secured to the top of the table II is a pedestal I" provided at the end adjacent the delivery end of the magazine or magazines I with a Jaw opening I" and through which the ferrule I4 of the brush unit 83 may be fed transversely of the pedestal ill.

Located within the jaw opening I" is the table or slide Ii. Also, on the lower portion of the jaw opening i", and beneath the delivery end of the magazine or magazines III, is an anvil I". In the upper end of the jaw opening III is provided a vertical slide Ill in which is slidably mounted a crow head in carrying the staple propelling member or members Ill, and which engage with the staples H14 in the magazine or magazines I II, and drive the same into and through the ferrule 04 of the brush units 63, and into the handle I, thereby firmly attaching-the handle II to the brush unit II. On the upper end of the pedestal III! is a shaft ill on which is pivotally mounted a lever H2 one end of which is provided with a cam roller H3, adapted to be engaged by the working surface of a cam 4.

This cam H4 is provided with a rather rapid rise lit for rapidly moving the end of the lever ill containing the roller H3 upwardly. A coil spring lilo, attached one end to the lever H2 and the other end to the pedestal I". maintains the cam roller lit in engagement with the cam H4. The other end of the lever H2 is pivotally attached to one end of a connecting link ill. The other end of the connecting link H8 is pivotally attached to the top 01 the cross head I". The cam IN is secured to the main drive shaft i5, preferably by means of the threaded bolt ll'l. By means of this connection the cam 4 may be readily disconnected from driving connection with the main drive shaft IS. The form of connection is such that any other form of tion, above described, to the first nailing station described above and illustrated in detail in Figs. 6, '7 and 8, thereby bringing the assembled brush units into operative relation with respect to the mechanism above described.

The nailing operation takes place in the manner just described, and when the staple engaging members IIO have cleared the ferrule 84 of the brush unit 63, the cam roller II3 will be in engagement with the cylindrical portion of the cam II 4. The next intermittent step of movement of the endless conveyor chains 23 will,

therefore, move the assembled brush unit from the first nailing position, above described, to the ment for heating the stamp or die and a movable stamp or die holding structure I22, which structure is moved periodically downward to bring the stamp or die into engagement with the brush handle being operated upon. Preferably, the printing mechanism operates in the well known manner where heat and pressure are applied to a stamp or die, and the heat and pressure are utilized to transfer some of the color from the roll I2I carrying colored material to the handle 65 of the .brush being operated on.

Preferably, there are twoof the printing stations and, therefore, two of the printing mechanism, it being desired to print indicia on two sides or faces of the brush handle I55. Under these circumstances, therefore, it is desirable and practically necessary to interpose between the printing mechanism a mechanism for tuming the brush assembly over, so as to bring the unprinted surface thereof into engagement to be operated on by the second printing mechanism. In Fig. 1, the second printing station is designated by the reference numeral I23, and interposed between the stations I20 and I23 is the turning station designated by the numeral I 24.

Assuming, therefore, that the first printing operation has been performed and that the endless sprocket chains 23, in their intermittent movement, have moved the brush assembly, just printed, to the next succeeding operating mechanism-in this instance a turning mechanismthe turning mechanism will take the brush assembly from the tables or slides 50 and GI and will rotate the same through an angle of 180, after which the turning mechanism will deposit the brush assembly on the tables or slides 80 and SI and be in position to operate on the next succeeding brush assembly.

The turning mechanism is illustrated in detail in Figs. 9, 10, 11 and 12, and referring to such figures there is shown'at the turning station I24, and below the table I3, the aligned bearings I25 and I26 and inthese aligned bearings is rotatably mounted a shaft I21. Secured to the shaft I21 is a gear I28which meshes with and is driven by a gear I29 mounted on. and forming part of the first printing-mechanism. Secured to the shaft I21, adjacent the gear I28, is a cam I30.

Mounted on the top of the table I3 is a pillow block I3I in which is rotatably mounted a shaft I32. Secured to the shaft I32 and extending downwardly therefrom is a lever I33 provided at its lower end with a camroller I34 engaging the surface of the cam I30.- Also secured to the. shaft I32 is an arm I35'provided at its outer end witha table or platform I36 adapted to be brought up through an opening in the table or slide 60 and support the handle 65 of a brush assembly, as clearly shown in Fig. 11.

Secured to the shaft I21 at the end remote from the gear I28 is a gear I 40. As may be seen from the end elevation in Fig. 10, this gear I40 is a segmental gear one half of the periphery of the gear being provided with gear teeth I while the remaining half of the gear I42 is plain or toothless. The gear I40 is adapted to mesh with and drive a gear I43 which is secured to a shaft I 44 rotatably mounted in a bearing I45 secured to the upper surface of the table I3. By reference to Figs. 10 and 11, it will be seen that the gear I43 is divided, about its periphery into four zones, such zones being arranged in pairs and diametrically arranged. For example, diametrically arranged on the gear I43 are the arcuate toothless portion I42 on the gear I40 to thereby permit the gear I40 to rotate to a certain angular space while gear I43 remains stationary. Also, diametrically arranged on the gear I43 are the teeth- I41, which teeth are adapted to be engaged by the teeth I4I on the gear I40, and whereby the gear I43 may be rotated to bring the arcuate portions I46 successively into operative relation with the toothless portion I42 of the gear I 40. As the gear I40 is continuously rotating it will be apparent that the gear I43 will be intermittently rotated and will make one revolution to two revolutions of the gear I40.

Secured to the shaft I44 at the end remote from the gear I43 is a cylindrical disk-like member I48, provided with aligned bosses I49 dimetrically arranged on one face of the same. Rotatably mounted on each of the bosses is a shaft, as the shaft I50. Secured to one end of each of the shafts I 50 on one side of the disk I48 is a jaw member I5I. Secured to each of the shafts I50 on the other side of the disk-like member I48 is a lever, one of such levers being designated by the reference numeral I52, and the other lever being designated by the reference numeral I53. To one end of the lever I52 is attached, through pin I54, a coil spring I55, the other end of this coil being attached, through pin I56, to the disk-like member I48. The coil spring I55, therefore, as viewed in Fig. 10, tends to rotate the lever I52 in a clockwise direction about the shaft I44. The other end of the lever I52 has rotatably mounted thereon a cam roller I51. Also, this other end of the lever I25 has pivotally attached thereto one end of a connecting rod I58, the other end of this connecting rod being pivotally attached to one end of the pivoted lever I53. The end of the lever I53 remote from the connection thereto of the link I58 has rotatably mounted thereon a cam roller I58, similar in construction to the cam roller I51.

As the shaft I21 rotates, the gear I40 is likewise rotated, that is continuously and, therefore, the gear I43 will be intermittently rotated, with a slight pause between each intermittent rotary movement, this action being possible because of the arcuate portions I46 of the gear I 43 and the toothless portion I42 on the gear I40, as above described. I 1

The jaws II carried'by the shafts I88 will, therefore, be likewise rotated and assuming the position of the parts being that shown in Figs. and 11, it will be apparent that when the shaft I21 rotates so as to bring the teeth I of the gear I40 into mesh with the teeth I41 on one of the sectors of the gear I48, that such gear I48 will be rotated through an angle of 180 so as to bring the now lowermost arcuate portion I48 of the gear I40 into the uppermost position and, therefore, vice versa, thereby, to rotate the Jaws I5I and any article that may be carried thereby through an angle of 180.

As the articles being worked on by the present machine are at the present time brushes, particularly brushes of the paint type, and as such brushes are normally flat on two opposite faces and it is desired to perform certain operation on such opposite faces, the jaws III are so arranged as to hold such paint brushes. to always present the fiat faces of the brushes to the working instrumentalities. This rotary movement is controlled by the gears I40 and I48, but has no effect on either opening or closing the jaws I" to permit the insertion and gripping, for the holding of the brushes therein.

This latter is accomplished in the following manner. On the shaft I21 is secured a gear I58. On the shaft I44 is'secured a gear I80 which is similar in pitch and diameter to the gear I 88. Interposed between the two gears I 58 and I88 and rotatably mounted on a stub shaft I8I is an idler pinion I82. In a bearing block I88, secured to the top of the table I8, is a shaft I84 to which is secured a gear I85. To thehub of the gear I85 is secured a cam I88. As the shaft I28 is continuously rotating the shaft I84 will likewise be continuously rotating, and, therefore, the cam I 88 will always be in motion, although not always in action. The train of gears I58,- I80, I82 and I85 is so proportioned with respect to the gears I48 and I43 that the cam I88 will be brought in engagement with one or the other of the cam III separated from each other or in open position, when the cam I88 rides past the cam roller I81 or I884, as the case may be, the coil spring I88 rotates the levers I82 and I88 and brings the jaws I5I into their gripping or closed position onto the next succeeding brush assembly.

From the turning mechanism above described the assembled brush is brought into operative position with respect to' the second printing mechanism, designated in Fig. 1 by the reference numeral I28, This second printing mechanism is identieal'in construction and operation to the first printing mechanism, I28 heretofore described, and, therefore, will not be described in detail.

In the continued intermittent movement of the endless conveyor chains 23, the completed brush assembly, after having been operated upon by the second printing mechanism I28 is moved into operative association with a second nailing mechanism I10. The particular details of the nailing mechanism are identical with the nailing mechanism heretofore described and illustrated in Figs.

= 6, '1 and 8, and. therefore, a further description rollers I51 and I58a. In other words, assuming the parts of the device to be in the position shown in Figs. 10 andll it will be noted that the gear teeth I are about to intermesh with the gear teeth 1 on one segment of the gear I48 and to rotate such gear I43. In this position the jaws ii are now clamped on the ferrule 84 of a brush unit and hold the brush firmly against movement. The gear I85 is rotating, but the cam rollers I51 and I58a will not be engaged by the cam I85 at this time. The gear 0 rotating, will rotate the gear I43 so as to bring the now uppermost arcuate surface I48 into the lowermost position as the beginning of the toothless portion I42 of the gear I40 comes into play and the gear I48 stops with the lever I53 occupying the position now occupied by the lever I52 and bringing the cam roller I58a thereon into the position now occupied by the cam roller I5'I in Fig. 10. When this thereof is not deemed to be necessary.

After leaving the second nailing mechanism I10 the brush assembly is brought into association with a brushing and forming mechanism designated in Fig. 1 generally by the reference numeral "I, and illustrated in detail in Fig. 13. Referring to such Fig. 13 it will be noted that the slideways 88 and H are associated therewith and over which slides are moved by the endless conveyor chains 28, the completed brush assembly including the handles 85 and brush element 88.

On top of the platen or table I3 is mounted a base I12 provided at its top with a bearing I13 which is rotatably mounted a shaft I 14. Secured to the shaft I14 is a pulley I15 which is in alignment with a pulley I18 secured to the main drive shaft I5. Over the pulleys I15 and I18 runs the endless belt I11 and by means of which power is transmitted from the shaft I5 to rotate the shaft I14.

Pivotally mounted on the shaft I14 is a hub I18 provided with a downwardly extending arm I18 having a bearing I at its lower end. Rotatably mounted in the bearing I80 is a shaft I8I. Secured to one end of the shaft I8I is a pulley I 82 which is in alignment with a pulley I83 secured to the shaft I14, and over the pulleys I82 and I83 runs an endless belt I84, and by means of which power is delivered from the shaft I14 to rotate the shaft I8I. Secured to the shaft I8I, on the opposite side of the bearing I 80, from the pulley I82, is a circular brush I85 which rotates in the direction of the arrow shown in Fig. 13. Also secured to the hub I18 is a downwardly extending arm I88, on the outer end of which is rotatably mounted a cam roller I81. Secured to the main drive shaft I5 adjacent the pulley I18, and in position to be engaged by the cam roller I81 is a cam I88. The function of the cam I88 and cam roller I 81 is to give to the circular brush I 82 an oscillating movement about the shaft I14 as a center, to swing the circular brush I82 into and out of operative position with respect to the bristles of the brush element 88, as clearly shown in Fig. 13.

In order to provide that the brush assembly composed of the handle 85 and brush unit 88 is held in fixed operative relation to the brush I82 we have provided the following instrumentalities. Adjacent the endless conveyor chain 23 carrying the fingers 25 on top of the platen or table II is secured a pedestal I88. Mounted in such pedestal I89 is a shaft I 90. Secured to the shaft I90 is a lever, one arm I9I of which is curved and provided at its outer extremity with a clamping jaw I92 which firmly clamps the handle 65 of the assembled brush onto the slide 60. Intermediate the ends of the lever arm I9I is provided a stop I93 which not only engages the end of the handle 65 to prevent rearward movement thereof, but which positions the brush unit 66 in operative relation to the circular brush I82. The other arm 194 of the lever, secured to the shaft I90, has pivotally attached at its free end, one end of a shaft or r'odI95. Secured to the other end ofthe shaft or rod I95 is a forked member I96. The spaced arms I91 of which straddle the main drive shaft I so as to permit rotary movement of the main shaft I5, while yet permitting a sliding longitudinal movement of the forked member I96 on such shaft. On the forked member I96 is mounted a stub shaft I98, on which is rotatably mounted a cam roller I99 and this cam roller I99 engages with the cam face of a cam 200, secured to the main drive shaft I5.

The cams I88 and 200 are so formed and so disposed on the main drive shaft I5, and are so related to each other and to the mechanisms operated or controlled thereby, that as the brush assembly formed of the handle 65 and the brush unit 66 are moved into proper position by the fingers 25 and 26, carried by the endless conveyor chains 23, the lever arm I9| is operated to bring the clamping jaw I92 and stop I93 into operative relation to the handle 65, to .thereby move the handle to the right as shown in Fig. 3 a sufficient distance to bring the brush unit 66 into operative relation to the circular brush I82 and to clamp the brush assembly in fixed position on the slide 60. After this clamping and positioning operation has taken place, the cam I88, engaging with the cam roller 881 on the arm, rotates the arm I19 about the shaft I14 as a center, and brings the circular brush I85 into operative position with respect to the bristles of the brush unit 66 to thereby brush and condition the same, after which the brush I85 is swung out of the way and into the position now shown in Fig. 13. Immediately thereafter the cam 200 operating in conjunction with cam roller I99. moves the rod or shaft I95 to the right, as shown in Fig. 13, raising the lever arm I91 to thereby free the assembled and cleaned brush and permit the same to be moved onward.

Upon leaving the brushing unit I1I described above, the assembled brush moves along the slides 60 and BI and downward along the curved portion 20I thereof. From the bottom of the curved portion 20I of the slides 60 and BI, the assembled brushes are collected in a holder or magazine 202, and the transition of such assembled brushes from the curved portion 20I to the magazine 202 is accomplished in the following manner. I

Referring back to the second printing mechanism I23, it is noted that this printing mechanism is provided with a main shaft 203. On such shaft is secured a face plate 204 provided with aradially extended crank pin 205,- Pivotally attached to the crank pin 205 is one end of a connecting rod 206. The other end of the connecting rod 206 is piovtally attached to the lower end of a lever 201 which is pivotally mounted intermediate its ends, on a shaft 208 carried by a bearing member 209, secured to the under face 'of the platen or table I3. The end of the lever 201, remote from the pivotal connection of the cess 2I0 into which the brush assembly slides from the curved portion 2M 01' the slides 60 and 6|. The rotation of the main drive shaft 208 of the second printing mechanism I23 by the mechanism above described imparts an oscillating movement to the lever 201, the end of such lever, within which is.provided the recess 2l0, swinging from the full line position shown in Fig. 1', in which it receives the'assembled brush, to the dot-and-dash line position shown in Fig. 1, where the finished brush is forced into the collecting magazine 202.

Referring now to Fig. 16, there is shown a plurality of views representing the complete series of operations above described and wherein the handle 65 and the brush assembly comprising the ferrule 84 and bristles 66 are shown in disassembled and assembled position, representing the condition of these elements when the same are in the assembling unit heretofore described with respect to Figs. 2, 3, 4 and 5. After the assembling operation, the brush elements 65, 66 and 84 are as shown in the group designated Assembling. After the first nailing operation by the mechanism designated generally in Fig. 1

by the reference numeral I00, and illustrated in detail in Figs. 6, 7 and 8, the appearance is that shown at the point designated "First nailing. The first printing operation is sufiiciently illustrated by the appropriate character in Fig. 16, and also the turning operation is designated as being a turning operation by the arrow in the appropriate figure, whereas the second printing and second nailing operations are also sufiiciently indicated in the appropriate stations. In the cleaning operation, so designated, the circular brush I82 has been shown in connection therewith in order not to confuse the brushing operation with other operations which have taken place.

In Figs. 17, 18 and 19, a different form of brush from that illustrated in Fig. 16 is shown, and in which the ferrule 84 of Fig. 16 has substituted therefor a ferrule 2II formed of any suitable,

but preferably of non-metallic material. Further, and as shown in Fig. 18, the end of the handle 65 is shown with a wedge shaped split 2I2 therein and in which is positioned a wedge 2I3, preferably of wood, and at any rate of nonmetallic material. During the assembling operation, therefore, and with regard to the type of brush illustrated in Figs. 17, 18, and 19, the assembling of the brush units 65 and 66 results in the forcing of the wedge 2I3 in the wedge shaped cut in the end of the handle 65. The ferrule 2| I, in this form of brush, has the perforation therethrough undercut as indicated by the reference numeral 2I4, with the result that the material of the end of the handle 65 is forced outwardly at its ends as shown in Fig. 19 as the wedge 2I4 is driven into the handle 35. In this type of brush, no fastening or nailing operations take place, and it is possible to either remove the nailing instrumentalities illustrated in Fig. l, and rearrange all the other instrumentalities, or merely disconnect the nailing instrumentalities shown in Fig. 1 from the operating power so that while the brush units will stop at the nailing stations no nailing will take place.

Whereas this invention has been described pursuant to specific forms thereof, it will be understood and agreed that many changes and modifications may be made without departing from the spirit of the invention.
