Application August 29, 1941, Serial No. 408,784

6 Claims.

My invention relates to tufting machines and more particularly to tuftlng machines of the multiple needle class for simultaneously forming rows of chenille on relatively long sections of cloth as it progressively passes through the machine.

This invention has particular reference to piece goods from which chenille garments of various characters may be made although it may be adapted to the production of bedspreads, and bath mats as well. Heretoiore in the art it has been the general practice to cut out the parts of the garments from the backing, apply the chenille to those parts and sew them together. This work is ordinarily done with a single needle machine due to irregularities in the shapes of the pieces that go to make up the garment, although in rare instances chenille has been applied to the backing before it is cut or to the backing after the garment has been made up therefrom. In these various instances the backing is progressively scanned with either a single or plural needle machine. These plural needle machines are ordinarily of the two. four, eight, or ten needle class wherein the needles are ordinarily carried by a single needle bar. In these types ofmachines. the needles are hung or mounted on the standard needle bar while the loopers and cutters are ordinarily mounted beneath and bedplate thereof. Since these types of machines are not designed for such heavy loads a great deal of trouble from breakdowns due to strains and stresses resulting from overloads occur. This keeps the machine out of operation a very substantial part of the time and greatly hampers production.

In the instances where the chenille is applied to the backing before parts of the garments are cut out it is necessary to ordinarily cut the backing into convenient lengths in order to facilitate the progressive scanning of its surface by the single or multiple machines. If it were attempted to apply the chenille to long sections of the fabric or backing there would be an endless task of rolling and unrolling the fabric as each row or set of rows of chenille is progressively applied until the entire width of the fabric is covered.

Applicant with the knowledge of all of these defects ,in and the objections to the prior art has for an object of his invention the provision of a multiple needle tuftlng machine whose needles completely span the width of the section of cloth, so that the machine in the single operation may insert tuftlng across the entire width of the section and thereby eliminate the necessity for progressively spanning the cloth.

Applicant has as another object of his invention the provision of a multiple needle tuftlng machine having a plurality of needles positioned at spaced intervals across the entire width of the fabric, which needles swing in an are on a reinforced supporting structure which will withstand the, impact of the piercing operation of the fabric by the simultaneous movement of the needles without material deflection or warping thereof.

Applicant has as another object of his invention the provision of a multiple needle tuftlng machine having an improved feed mechanism for progressively moving long pieces of cloth through the machine.

Applicant has as another object of his invention an improved mechanism for spreading a relatively long section of cloth transversely to remove the wrinkles therein just before the cloth passes under the needles of the machine whereby to secure uniformity of spacing. of rows of chenille throughout the width thereof.

Applicant has as another object of his invention the provision of a tuftlng machine having a plurality of spaced needles for moving on an arc to pierce the fabric and a plurality of individual cutters and loopers for coacting with the needles to simultaneously produce loops and sever them to form tufts, which loopers and cutters are mounted on relatively long shafts which bridge the ends of the frame of the machine and supports having engagement with intermediate portions of both of the shafts to provide additional support for them and to constantly maintain the spacing between the shafts during their movement and during the cutting operation while force is being applied thereto.

Applicant has as a still further object of his invention the provision of a plural needle tuftlng machine which will automatically feed and guide the cloth therethrough and which will automatically insert the chenille therein and deliver the finished goods therefrom.

Applicant has as another object of hisinvention the provision of a tuftlng machine which will apply tuftlng to fabric as it is removed from'the roll and which will provide for movement of the roll endwise to compensate for irregularities in the cloth and its wrapping.

Other objects and advantages of my invention will appear from the following specifications and accompanying drawings and the'novel features thereof will be particularly pointed out in the annexed claims In the drawings Fig. 1 is a rear elevation of my improved tufting machine.

Referring to the drawings in detail 1 designates the frame of my improved machineand may conveniently be the frame of a conventional loom 'vvhich has been converted. This frame may be of structural steel and may have base membersIIB, III; which join the ends 1, 1 of the frame." The frame may also be comprised of lower steel side portions or members which join the lower portions of the ends 1, I. Mounted on one end of the base elements H6, H6 and bridging them is a supporting base 1 for an electric motor H5. This motor may be of the conventional type, that is a single, double, or triple phase induction motor or'an appropriate D. C. motor. Of course, the conventional electrical leads or conductor (not shown) pass from a source of electrical energy to the motor. The motor has adjacent one of its ends a shaft extension and a pulley ||4 mounted on such extension and having one or more grooves for coaction with V belts or other appropriate means. Mounted intermediate the frame and bridging its .ends is a central drive shaft 2| joumaled in appropriate bearings I00, I00 mounted preferably' on the inner faces of the ends 1, 1 of thereof and mounted on one end is a pulley II2 having grooves therein for cooperation with V belts I I3 bridging the pulley on the motor II! and the pulley I I2 on the machine. The shaft 2| is also supported intermediate its ends in a bearing 99 on the end of an arm extending upwardly from the side members of the frame. Mounted on and intermediate of drive shaft 2| is a hand wheel 98 for turning the drive shaft manually and independent of the motor 5 primarily for use when threading up the machine.

Positioned on an intermediate portion of the frame and adjacent the top thereof is a V shape angle iron or channel element 21 (see Fig. 9) which bridges the ends 1,1 of the frame. Mount- .ed on and carried by the angle iron 21 is an L shaped angle iron 3| which bridges the ends 1, 1 of the frame and abuts against the interfaces of an extension of such frame. Spaced from the angle iron 3| is a similar L shaped angle iron 32 secured in overlapped relation to a plate 28 mounted on the extension of the ends 1, 1 of the,frame. Bridging the angle irons 3|, 32 and extending across the frame and carried by such angle irons is a throat plate 33. Positioned beneath the throat plate 33 and mounted on the plates 28 at either end of the machine are rock shafts 29, 30. Adjacent one or both ends of the rock shaft 29 is mounted an expansible block I48. Located opposite each block I46 and mounted on rock shafts 30 through bolt 9 is an arm II8. Joining the block I46 and the arm H8 is a pivoted link |2I being joined thereto by pivot pins I22, I20, respectively. Mounted adjacent one or both of the blocks I46 is an expansible block I23 having a bore for the reception of shaft 29 and having clamping jaws actuated by clamping bolt 4 for tightly gripping shaft 29. Adjacent the other end of clamping block I23 is formed a longitudinal slot I25 through which studs I21 and washers or nuts I28 pass for mounting a socket on one face of the arm in adjusted relation thereto. It will be understood that the bolts I21 screw thread into the socket and may be tightened to maintain such socket in any desired position as is well known in screw and slot connections. Disposed within the socket 24 is a ball I26 mounted on the upper end of arm 25 whose lower end is disposed about a cam on shaft 2| for reciprocating the rod and oscillating the shaft 29. v

Mounted on the channel iron 21 (see Fig. 10) at one or more places intermediate the end thereof is a. bracket I33 having a portion I29 for engagement with channel member 21 and secured thereto through studs I30 passing through the bracket and screwthreaded or otherwise secured to channel 21. A lateral portion extends at right angles from portion I29 and is resilient or yieldable for supporting shafts 29 and 30. The outer end has a curved finger thereon for engagement with" and reception of shaft 29. Stud |3I passes through the bracket and is brought into supporting engagement with shaft 30. It is maintained against turning by locking nut I30. This maintains a constant relation between the two shafts 29, 30. Positioned over the bedplate 3|, 32, and 33 of the machine is a needle carriage, shown in detail in Figures 20, 21, and 22. This frame is made up of end members-I6, I5 bridged at spaced intervals by side members I34, I35, and I36, which frame members are in turn reinforced by cross-members providing a strongly fabricated and reinforced carriage of angle irons. Dependingfrom the lower front edge and extending sub- 'stantlally the full length of angle iron in are blocks I56, I providing spaced sockets for the reception of the upper ends ofneedles is which are locked in place in such sockets by set screws .20 which extend into the side walls thereof. Formed in the upper flange of said member I36 are a series of spaced openings I31 for the passage of thread I to needles l9.' Intermediate member I35 may have like double alined openings in its upper flange. Mounted on the upper surface of the rear side member I36 are a series of tighteners n for tensioning the strands of yarn as they are fed to the needles l9. These tighteners are preferably staggered in the two rows in Fig. 20. These tension devices are of conventional structure such as shown in Fig. 4, consisting of an upri ht shank mounted on member l36 having an upper reduced threaded portion adjacent its upper free end [6 with a nut l2 having a roughened outer surface coacting with the screw threads of the shank, a helical spring l3, two disk plates II, II are interposed between the shouder defined by the reduced portion of shank l and the nut I2. The compression of spring I3 may be altered by the action of nut l2, and the pressure or force with which disks II, I l are urged towards each other may be varied. Of course, it is understood, that the strand is disposed between the plates H, II and its relative movement controlled by the pressure of the plates thereon in a well known maner.

Mounted on the inner faces of the rear ends of. members l6, l6 are balls l8, l8 which coact with sockets inbrackets (not shown) carried by extensions 6, 6 of the frame I. This permits the carriage to rock about balls l8, l8 asa pivot so that needles l9 mounted on the front thereof move in an arcuate path. Mounted on the outer face of the front end of members l6, l6 are balls II, II which coact with and are received in sockets 23, 23 on the upper ends of rocker rods 22.

The lower ends of rods 22 are formed into sockets for disposition about cams on the drive shaft 2| for reciprocating the rods 22, 22 to rock the carriage about its pivots l8, l6 in a swinging movement.

Mounted in advance of and positioned above and below the bedplate of the machine are a plurality of spreader rollers 84, 85 and 66. See Fig. 14. These rollers each have a plurality of spiral ribs extending outwardly towards each end thereof from the center. These rollers are preferably cylindrical in configuration and rollers 85,

86 receive their ower from roller Bl'being connected therewith by belts 96, 94 through such pulleys as 89, 90 and-9l, the belt on pulley 89 being reversed or crossed so that it rotates in a direction opposite to that of its corresponding pulley on roller 84. Roller 84 in turn receives its power through pulley 92 mounted thereon and belt 95 which coacts with pulley 91, mounted adjacent one end of drive shaft 2|.

Mounted on the opposite end of drive shaft 2| from that of the driving pulley H2 is a cam for actuating the feed mechanism to be hereinafter described (see Fig. 13). Rearwardly of the'bedplate of the machine and in substantially vertical alinement and extending across the machine are upper and lower feeder rollers 62, 63. The lower roller 63 is mounted on a shaft carried by the frame 1 of the machine but may be adjusted towards and away from the upper roller by any appropriate means. The upper roller is mounted at one end in the frame I and at the other end its shaft .65 is carri'ed byoan angle bracket 69 having a lower end secured through. stud 10' to the frame I and the upper end extending outwardly from such frame. This provides clearance for movement of the arm 26 which actuated cross memb r 10. The upper roller 62 has a coating of rubber 64 (see Fig. 12) formed on the metal base of the roller 62. This gives the roller better adherence to the cloth which is being progressively pulled through the machine. Mounted on the shaft 65 adjacent the standard or bearing 66 is a pivoted cross. member 10, heretofore referred to. The lower end of this member 10 is slotted or grooved to receive the pivot pin 15 in adjusted relation in order to somewhat vary the length of the stroke. Mounted pivotally by pin 12 on the upper end of cross member 10 is a-pawl H which is actuated into contact with the teeth of a ratchet wheel 66 in the usual manner by a spring 13 set in the innerface of the cross arm adjacent its upper end. The ratchet wheel 66 is mounted on the shaft 65 adjacent the cross arm 10 and is keyed or secured to the shaft 65 by appropriate means. A resilient finger I9 is mounted on the frame 1 by a stud or other support which ten sions the resilient finger I9 against the ratchet wheel 66 to retard its moving, and act as a brace in the usual and well known manner,

Mounted rearwardly of the initial feed rollers 62, 63 and carried by the upright extensions 6, 6

of the frame are additional feed rollers 53, 5|

(see Figs. 2 and 3) mountedin vertical alined adjusted relation. These rollers are mounted on flanged plates 56, which flange are secured adjacent their upper ends to the extensions 6, 6 of the frame. The lower plain surface roller 54 is mounted on a shaft 55 or otherwise bridges the plates 56, 56. The upper r0ller 53 has a knurled outer surface as indicated in a detail of- Fig. 11. It is mounted on a shaft 55 which extends or projects some distance beyond the roller at one end. Thi upper shaft 55 passes through slots -in the supporting brackets 56 and is journaled on ither end on blocks 51. These blocks in turn have slots therein to receive retainer pins 58 loosely passing therethrough and seating therein. Mounted on block 51 and extending laterally therefrom is a finger 59 which engages and interlooks with one end of a tension spring 60 whose other end is secured to bracket 56, as at 6|. The.

purpose of this arrangement is to tension the upper roller 53 against the lower roller 54. The extending free end of the upper shaft 55 has a pulley 11 mounted thereon, which pulley is joined through belt 18 to a pulley 16 on shaft 65, which latter pulley is positioned adjacent the ratchet wheel 66 for transmitting the power therefrom to pulley 11 on the upper shaft 55 for rotating that shaft. Mounted on either end of frame I is a standard 68 carrying'a pivoted arm 61 for adjustment to any desired or appropriate position. Formed in the upper end of each arm 61 is a groove which serves as a bearing for supporting a roller or stationary cloth guide 66 abridging the space therebetween.

Extending upwardly from the frame I at its corners are four upright or extensions 6, 6 having a supporting structure 5 made of fabricated steel for supporting various cones of yarn 2. Additional members extend up from the supporting structure 5 and additional members bridg the upper ends of these extensions and extend on the removal of the thread or yarn from the cones 2. Mounted on th uprights 3, 3 intermediate their ends is'a bowed thread guide 3 of relatively thin material having a great many openings thereto for the passing of yarn.

Mounted forwardly of the frame 'I- on projecting arms 43 is a roll of fabric or backing 4.

Passing through the roll of backing 4 is a shaft through said opening is a stud .43 which may be locked in adjusting position by a lock nut 43. To clarify the mounting of shaft 44 this finger and stud and lock nut have been omitted from Fig. 5 although it is clearly shown in Fig. 6. To limit the endwise movement of the roll of cloth on shaft 44 cone shaped collars IOI, shown in detail in Figures 6 and 7, are clamped about shaft 44 by means of resilient extensions 50 through which bolts 5I pass and which are clamped by nuts 52 thereon.

Mounted on the frame adjacent the roll 4 of cloth 3 are guides 33, 33 which project inwardly from the ends of frame I above and below the cloth for limiting the-upward and downward movement thereof. On beyond the first cloth guides 33, 33 is located a guide 3| (see Fig. for limiting the endwise movement of the fabric as it is fed through the machine. This guide consists of a shank 3| having a cross-member on its end for engagement with cloth, and this shank is mounted on frame I in adjusted relation thereto through nuts 32, 32 which engage the screw threaded end portion thereof. It will be understood that a guide of this character is provided on either end of th machine.

As will be seen from Figures 18 and 9 a series of loopers I42 are mounted in spaced relation along shaft 29 by means of split collars or blocks I33, which collars or blocks are clamped about the shaft 23 by clamping studs I4I. Each of these blocks I33 have transverse bores for reception of the staffs or shanks I33 of the loopers pomtioned opposite clamping studs I. They may be clamped in adjusted relation in the bore by means of set screw I40. Th upper ends of the loopers terminate in a hook of thin hardened steel which is welded or otherwise secured to the shank I33. Mounted on the rock shaft 33 in coacting relation with the loopers I42 and tensioned against them for sliding engagement thereon are a series of cutter blades I43 each having a sharpened upper end for coacting with the sharpened edge of the conventional looper. The mounting for the cutter blade I43 consists of .a bolt passing through a bore in a rectangular or square shaft 30 and held in place by clamping nut I45. Formed in the shank of the bolt I44 adjacent its head is a longitudinal slot for the reception of the lower part of the body of the cutter blade I43 so that upon'tightening of the nut I45 the cutter bladeis clamped in adjusted relation between the head of bolt I44 and the flat wall of shaft 33. Positioned above the throat plate 33 is a presser foot 34 which is normally tensioned against the upper'face of the throat plate 33 by nieans of studs extending upwardly from the bed plate of the machine and passing through presser foot 34 and having a nut 33 screw threaded on the upper end thereof and a washer 31 and a compression spring 33 interposed between nut foot (see Fig. 16)

Reinforcing or strengthening blocks are positioned over the presser foot 34, engaging it, and are secured thereto, and extend along it throughout substantially the whole of its length. Registering with the openings and grooves or slots of the presser foot are formed elongated openings in the throat plate 33 as indicated at 4I of Fig. 17. The central portion of these slots are reduced while each end is enlarged as indicated at 42. The needles reciprocate in the large forward openings 42 while the strands or tufts progressively move rearwardly through the reduced portions of the slots and are removed from the bedplate through the enlarged rear portions thereof.

For stopping a machine after the power has been cut off an appropriate brake is provided. This brake consists of a foot lever IIO pivotally mounted on a bracket I03 carried on one side of frame 'I by appropriate studs or other means. Pivot pin III pivotally mounted on the bracket I03 carries an arm I04 which in turn pivotally supports a rod I01 at one end. The rod I01 is also supported by a strap I02 secured to a side of the frame I through studs or other means. The end of rod I01 extends through an out turned portion of the strap and at the free end of the rod I01 is a compression spring I03 and nut or washer I03. Rigidly mounted on the rod I01 is a brake shoe I05 which is adapted to engage and work against the inner surface of the .rim or flange of the drive pulley II2.

In its operation the cloth 3 is mounted on the shaft 44 in the form of a roll 4. Cones of yarn, one to each needle, are positioned on support 5 and the cloth 3 is threaded through the machine passing between guides 33, 33 past guide 3I, under spreader roller 34, over spreader roller 35, under spreader roller 33, over the bed plate and under the presser foot 34, on to and over guide 33, between feed rollers 32, 33 and. on between feed rollers 53, 54. The thread I is then passed through the hook guides 3, 3 through an opening in guide 3, through an opening in side member I35 then about tensioning element I3 and then back through openings in side elements I34 and I35 and then through the eyes of the needles I3. I

The switch is now closed completing the electric circuit to the motor supplying the necessary power thereto. This causes the pulley H4 and in turn pulley -II2, when viewed from the end of the machine where these pulleys arelocated, to rotate in a counter-clockwise direction causing drive shaft 2i to turn in a counter-clockwise direction and to rotate the various cams and pulleys mounted thereon in such direction. This reciprocate the driving rods 22, 22 up and down and causes the needle carriage to oscillate in an arcuate path, intennittently passing the needles mounted thereon through the slots in the presser foot and bed plate. and successively piercing the fabric as it moves acros the bed plate and through the machine. Likewise reciprocating rod 25 is made to reciprocate and to rock shafts 23 and so through the linkage m, us, m, "m, thereby'actuating' the series of loopers and cutters in a manner to be described in more detail progressively engage the teeth on the ratchet wheel 66 and intermittently rotates shaft 65 in a counter-clockwise direction for rotating pulley l6 and roller 82 in a counter-clockwise direction, and in turn rotates roller 53 in the same direction. This progressively moves the cloth through the machine. The rotation of shaft ii in a counter-clockwise direction rotates pulley 91 with it and imparts through belt 95 a counter-clockwise rotation to rollers 84 and 86 and a clockwise rotation to roller 85 through belts 96, 94, as heretofore indicated. I

These various operations cause the needles l8 to move down through the fabric on the base plate and to pierce such fabric and be extended on below the base plate passing their strands of yarn through the fabric. Upon reaching the lowermost position of their travel the needles again start their upward movement developing slack in the loops thus drawn. At this time the loopers I42 swing towards the needles and pass between them and their respective strands of yarn, catching the loops and holding them as the needles move on up out of the fabric. After the needles leave the fabric the feed rollers 62, 63 and 53, 54 move the cloth rearwardly and during this interval the loopers I42 also move back out of the plane of the path of travel of the needles. The cutter blades now ride up the face of their respective loopers and coact with the cutting edges on the looper hooks to shear or otherwise sever the loops thereon. Ordinarily, the bill of the looper is made somewhat longer than the width of the cutter blade I43 so that the cutter blade does not ordinarily sever the first loop placed on the looper. If the first operation of the blade does not find a loop over its cutting edge during the first cycle, no cutting occurs but the various loops still remain uncut on the loopers.

This cycle is now repeated with the needles again piercing the fabric and carrying the yarn therethrough to form loops after which the loopers again pass between the needles and their loops and catch them, forming a second set of loops which push the first uncut loops back along the cutting edge of their looper after which the cutter blades come up and clip or sever the loops forming piles. This operation is completed over and over again simultaneously forming rows of tufts across the width of the fabric. A great many needles are used in such a machine, usually in excess of 57 needles and their spacing is ordinarily from a quarter to five-eighths inch although this may be changed to suit the convenience of the user.

A raised portions of cloth or tufts pass beneedles which may not be apparent from an inspection of the drawings is that it reduces or prevents looping, tearing of cloth and etc. Since the loopers I42 only move a relatively short distance, and must move in synchronism, it sometimes happens that slight irregularities in adjustment or lost motion, or loosenessor bending of needles or loopers prevent one or more of the loopers from catching their loops, thus causing looping, especially where the distance to be traveled by the loopers is great. The use of a swinging needle carriage which results in moving the needles toward the loopers on their downward swing reduces the necessary length of travel of the loopers and aids in moving the loops back on the hooks of theloopers. 7
