roman-MACHINE;

proved pullergs shown attached, is of the or-'--- dmary construction, and as shown in the drawings, is provided with two needles, 1, 1, whlch are carried by the needle bar 2 reciprocating in the head 3 supported on the overhanging arm 4. The presser bar 5 carries a presser foot 6 at the usual lever 7 for lifting the same is of the machine. I have also provided a lever 8 pivoted to the head of the machine, which extends-underneath the stud 9 mounted on the presser bar 5,and said lever 8 is operatively connected by asuitable'chain'or otherflexible connection 10, to a treadle or knee lever,

whereby the same may be lifted. The work support 11 is spaced from the bedpplate of Patented any 6, 119115;. Application filed June 15, 1907. Serial No. avaais.

srncmr. nmcnn'm the lower end, and

the machine 12 in the usual manner; The

feeding mechanism is the ordinary four -motion feed, and comprises a feed bar 13 carrying afeed dog 14. Said feed bar is end, through which said feed bar is/given its longitudinal or feeding movements. The feed bar is given its rise and fall from'the usual eccentric mounted on the main shaft. The rocking frame 15 has an arm 16 rigidly secured thereto, and said arm is pivotally pivoted to the rocking frame '15, at its rear connected to an eccentric strap 17 by aball I stud connection 18, as clearly shown in Figs. 3, 5 and 6. Said eccen'tricstrap 17 surrounds an eccentric 19 adjustably se cured to a supporting plate 20. Said-eccen-" trio 19 is provided with a dove tail portion 21, which engages acooperating dove tail projection carried .by the support 20. The

support 20 is rigidly secured -to the 'main by a set screw 22,.as shown in shaft 21 Fig. 6. Thls support 20 is provided with I outwardly extending which is passed a bolt portion 25 secured thereto between the ears 23, 23, whereby the bolt 24 is held in said ears, so that the same said-bolt is ears 23, 23, through prevented from longitudinal .movement through said ears. The enlarged --portion 25 preferably has its sides slabbed, whereby the vsameimay be engaged by a wrench. The bolt 24 is provided with right .and left hand threads at its opposite ends.

' The eccentric 19 is providedwith av perforated lug 26, which is threaded for engage ment with the bolt 24 24 having an enlarged may be rotated, but

' hanging arm 29, carrying at the forward eccentric 19 is slotted as at 27, (see Fig.

' shaft.

rollers with circumferential grooves 41, 42,

- of sufficient depth so that when no material My improved puller consists of a bed plate plate .28, from which rises an overend thereof a head 30, in which reciprocates a rod 31, carrying at the lower end thereof one member of the feeding mechanism of my improvedpuller. The bed plate 28 of the puller is provided with suitable supporting brackets 32, 32 (seerFigs. l and 3). On said brackets is the cloth plate or work-support 33. The supporting brackets 32are of such height that when said puller is mounted on a common base 34 (see Fig. 2) with a sewing machine, the cloth plate 3.3 of the puller is in the same plane withthe cloth plate 11 of the sewing machine, so that material operated upon by the sewing machine may be passed directly from one cloth plate onto the other.

Passing through the brackets 32 is a shaft 35 which carries at its forward end a feed wheel 36, which cofiperates with a feed wheel 37 rotatably mounted in the yoke 38 secured to the lower end of the bar 31, as shown in Fig. 1 of the drawing. The feed rollers 36' and 37 as clearly shown in Figs. 1 and 2, are provided w'th-projecting ribs or teeth 39 and 40, respectively, which are so shaped and spaced that one intermeshes with the other. I have also provided my feed which are spacedthe same distance apart as 'the needles of the sewing machine, so that stitches formed by the stitch-forming mechanism of the sewing machine will pass through said grooves and all liability of crushing or destroying the stitch in. any way, is avoided. The grooves, however, are

is. passing between the rollers but the machines are chaining from one stitched article to another, the chain of stitches will be engaged by. the feeding rolls and fed along,

' although said chain of stitches should lie in the grooves.

In order to intermittently rotate the feed wheel 36, I have provided the shaft 35 with a suitable clutch mechanism, which is operated from an eccentric carried by the main shaft of the sewing machine. Said clutch mechanism consists of a collar 43 (see Fig. 7 secured to the main shaft 35 by means of a set screw 44. Said collar is provided with an enlarged bore 45 in one end thereof, into which fits a sleeve 46, loosely mounted on the shaft 35. Saidcollar is also provided with cam-shaped recesses 47 (see Figs. 5 and 7), in which are located small rollers 48, 48. A spring 49 is seated in said recess, and normally. forces the roller up the cam surface of the recess into gripping contact with the sleeve 46. Said sleeve 46 has rigidly secured thereto an arm 50. When said arm 50 is vibrated in the direction of the arrow shown in Fig. 5, the sleeve 46 through the rollers 48 grips the cam face of the recesses in the collar 43, and turns said collar, thereby imparting a movement to the main shaft 35. When, however, the sleeve 50 is vibrated in the opposite direction, the rollers 48 are moved out of gripping contact with the collar, 43 and the sleeve is moved relative to the main shaft.

In order to provide a means for holding the main shaft from backward movement when the arm 50 is vibrated in the direction opposite from that shown by the arrow in Fig. 5, I have provided a bracket 51, which is secured to the bed plate of the puller 28 by suitable screws, and at its upper end is secured to a collar 52, which is loosely mounted on the main shaft, and which is also provided with an enlarged bore or recess 53, (see Fig. 7 which receives a reduced portion of the sleeve 43. Said collar 52 is provided with recesses 54, 54, having cam faces similar to *the recesses formed in the collar 43, but oppositely disposed relative thereto. Said recesses 54 are each provided with a roller 55 and with a spring seated in said recess 54, and engaging said roller, whereby the same is normally held in gripping contact with the sleeve 43.

The manner of operating my clutch will be obvious 'from the above description. As the arm 50 is vibrated in the direction of the arrow in Fig. 5, the sleeve 46 will grip the collar 43 through the gripping rollers 48, and turn the main shaft to the extent to which the arm 50 is vibrated when the arm 50 is moved in the opposite direction. The gripping rollers 55 will .;clutcl1 the sleeve 43, and prevent .the main shaft from rotating in a backward direction. By

this form of vibrating clutch and locking clutch, I have provided a clutch mechanism,

whereby small increments of movement may 56 to an eccentric 57, mounted on the main shaft 21 of the sewing machine. Said eccentric 57 is provided with a portion having mettle a dove tail recess 58, which engages a cooperating dove tailed projection 59, mounted on the support 20, above referred to.

given to the main shaft of the puller, is varied. As above noted, the bolt 24 is provided with right and left hand threads and the eccentrics 57 and 19 are disposed upon opposite sides of the center of the main shaft, as clearly shown in Fig. 5. By turning the bolt 24, therefore, the eccentrics will be simultaneously moved toward or from the center of the main shaft and the throw of said eccentrics will, therefore, be simultaneously adjusted. If the eccentrics are timed so that the throw of each eccentric causes anequal movement of the sewing machine feed and the feed of the .puller, for any given length of feed, when said length of feed is adjusted by moving one eccentric away from thecenter of the main shaft or toward the same, the other eccentric will be similarly moved, and a similar adjustment would be made in the movements of the puller feed. By this arrangement of parts the two feeds may be set to move in unison and whenever the feed of" the sewing machine is altered to lengthen the stitch, the feed of the [puller will be correspondingly altered, and the feeds will still move in unison. Suitable check nuts 60* and 60 are provided, to hold the eccentrics in their adjusted position.

The feed roller 37 is held in engagement with the material by a'fiat spring'61, mounted in the overhanging arm of the puller, and

having one end thereof resting on a lug 62 while the other end thereof engages the collar 63 on the, rod 31. The screw 64 en:

gages. the spring between its ends and by ad ustingsaid screw the tension of the spring may be increased or decreased, and

the pressure of the feed roller 37 on the material correspondingly varied :As a means for lifting the feed roller ,37 from the-material, I have provided a lever 65, pivoted at 66 to the overhanging arm 29. The forward endof said lever engages alstud 67 secured .to the rod 31, while the other end of said lever .is provided .with an eye 68, which is engaged by a suitable chain or other flexible connection 69.. As shown in Fig. 2, the-flexible connection or chain 69 and the chain 10, are joined together and connected by a single chain "to a knee lever or foot treadle, so that the presser bar of the j sewing machine and the feed 37 of the puller may be simultaneously lifted from the material whenever desired. The lever.

' ters Patent, is:

is held by means of a spring 70, normally in contact with the lug 71 on the head of the machine. i

The operation of my device will be obvious from the above description. The puller is attached to a sewing machine or any other machine'in which it is desired to I assist the feed thereof.v The material after passing through the machine, is passed to the puller between the feed rollers thereof, and as the feed of the main machine opcrates the feed of the puller will be operated in unison, and the material pulled through the machine. If desired, the stroke of the puller feed may be so adjusted as to be slightly in excess of thatuof the feed of the main machine and thereby the material put under slight strain.

It will be obvious that instead of operating the puller from an eccentric on the main shaft said puller may be operated from the rocking frame of thefeed dog or from any other suitable mechanism, whereby the same may. be moved in unison with the feed dog of the machine. If said puller were operated from the rocking frame of thefeed dog, then all adjustments of the feed dog whereby the stroke of the feed is varied, would produce a like variation in the feeding of the puller, so that the feed of the puller and the feed of the main machine will be kept in unison for various lengthsof feed movements. I

It will be obvious that from certain aspects, my invention is not limited to rotary feeding wheels, but that any'other form of intermittent feed may be substituted therefor, the-essential feature being that the feed of the puller shall operate in unison with the feed of the sewing machine-for 'all variations in the length of stitch. When it is desired to adjust the throw of the puller independently of the feeding mechanism of the sewing machine, the nut 50 (see Fig. 4), may be loosened,and the connection between the link 56 and the lever 50 moved toward or from the center of the shaft. 35. The arm 50 is-slotted at 50* to allow of this adjustment.
