This-:inventlon relates "to tun-sewing machines of the-type having material".feedingi discs and a horizontally operating needle. Morerparticularly, this invention relates ;to novelxguideimeans for feeding fur; pieces to the materialieeding dlscs ari'dzneedleof suchcfursewing machines.

The guide in accordance with this invention is aparticularly adapted LfOlI USB ink connection with the-welleknown fur'sewing machines:whichuuti lizera horizontally operating needle; to which. :the fur pieces to be sewn areifedrby ztheause oigop' posed horizontaletoothed: idiscs, one. :of which is driven intermittently .to control 'zthexstitich' end to allow a periodwof: ino motionwhile the zneedl'e is throughithe material: and-the iother :of which is 'free ,torevolve in meshwwith: the first. disc; The

In utiliz'ingsuch al. fur sewing imachinfinapair of fur skins are placed with itheiliur .side of t-he skins together and the edges are sewn in such a manner as to leave a flatseamwith the skin edges together after the material is placed. in the normally flatconditionlof use.

This sewing-operation requiresa large amount of skill and experience on the part-of the-operator. Further, the numerous operations require much time even for the. mostiexperienced and skilled operators. Itis necessary to maintain the edges of the two strips beingsew-n perfectly-even. Further,,theheight .of the edges i130 be sewn must be very accurately adjusted in relation to the positionof the. needle- Again,,.the operator must manipulate the stripsto prevent. the fur from being sewed. inthe seam; it being necessary-t turn down the fur. oneaichstripsothatl'bythe time theldiscs are .reach'ed'tljie fur.isiout of..w.-the way ofthestitchlngline.

It is, therefore, an object. of" this invention. to provide meansfor guiding iur stripsso that they will be accurately sewn.

It. is a furtheriobjeoti of. this invention .to provide .a .lfur sewing machine-having guiding means which eliminates :the. necessity for having highly skilled operators who have :been trainedafor ;a long period of. time and have. had considerable experience. i

Figure '7 is a cross-sectional view taken-on :the plane indicated by the line 1-1. Figure- 6, of the cam shown in Figure 6.

As shown in 'Figures I through 3 a fur sewing machine 2 in accordance with this invention has a base 4 supporting -a frame 6. belt 13 driven by a motorinot shown) inturn :drives' a pulley l0. Pulley I0 is connected-to and drives a disc [2 which is horizontally-mounted for rotation on frame 6. An arm M which is mounted onifrarne 6 carries a freely rotatable horizontal disc '6. Arm l4 can be manipulated so as to carry the disc 16 away from disc 12 for :thepurpose of insorting fur strips between the discs... A horizontally operating needle, as shown at I8, is adapted to be received in needle guide 20. A looper 22 extends from frame 6 to a positionedjacent needle l8 with which it coacts.

The above. description. is abbreviated since all of the mechanism therein described is widely known in the :fur sewing art. Additional information regarding the well-known fur sewing machine described above can be obtained by referring to Patent No. 2, 132,3'79, issued October 11, 1938, to C. Bonis.

The particular features of this invention as embodiedin the fur sewing machine .2 will now berspecifically described :by way of illustration;

.A uide .2 4 is secured {at 2.6 to an angled :lever 28. Lever 28 has a downwardly extending-arm :30 which ispivotally c'onnectedat 32to1a frame 34- which is secured to arm: 14. 7A, brace 35*: 1s connectedito' framewfi and la -bracket ifiradiacent frame 34. A stop member 36 is threadably secured to frame 34 and acts to limit the travel of arm 30 to the right as viewed in Figures 2 and 4.

Lever 28 is biased in the clockwise direction as we view Figures 2 and 4 by a coil spring 3'? which has one end secured to a strip 38 which is secured to lever 28 and the other end secured to a strip Ml which is secured to frame 34.

A lever 44 is pivotally secured to a bracket 46 mounted on frame 34. Lever 44 has secured thereto a cam 41 which coacts with lever 28 to cam it downwardly into operating position against the bias of spring 31. An operating lever 48 is pivotally connected to lever 44 and may be connected to an operating foot pedal (not shown). The guide 2a is shown cammed down into the operating position in Figure 4.

Lever 44 is provided with a cam member M which coacts with a set screw 455 secured to bracket 39. When stop member 3: is in contact with arm 35, set screw 49 is adjusted to'be in contact with cam 4?. When arm M is moved outwardly from. frame 6 incident to an increase in the thickness of the strips being sewn, forcing disc l6. away from disc [2, cam ll is carried to the right as viewed in Figure 2 and lever-M is moved upwardly. This causes cam M to move away from arm 28 and permits guide 26 to be raised. This arrangement takes care of the requirement that thin skins must be sewed closer to the top edges'of the strips than thick skins,

Referring now more particularly to Figure 4 and 5, the guide 24 has a flared shoe 58. The flared shoe 5!] has sides 52 which are substantially vertical near the front end 5 5 and flare outwardly as they extend rearwardly, the top plan view giving an appearance similar to a bicycle seat. A separating blade 55 is secured to the shoe 5!! by a clip 58 which also provides a means for securing the shoe to arm 28. Blade 55 has a slot 63 which permits the blade to embrace the shoe 5!) at its center line and yet gives the blade freedom of lateral movement. Blade 56 is provided with small notches on its rear edge as shown at 62.

A separating guide 64 is formed of a piece of wire having its two ends secured, as by soldering,

to the top of shoe 5b, as shown most clearly in Figure 1. Separating guide 54 extends down wardly in advance of blade 55 and in planes lying r to either side of the blade to a point below the bottom of the blade.

Sides 52 are slotted at 56 to provide play for the accommodation of combined fur strips having different thicknesses.

In the operation of the fur sewing machine of this invention the leading end of the fur strips "to besewn are brought together with the'fur sides facing and hand-fed between discs l2 and I6 and a few stitches are taken. The guide 2 is then cammed into the operating position shown in Figure 4 in the operation of lever 35 and its associated mechanism. The sewing operationcan now be started and continued until the strips are sewn together along their full lengths. The for is parted and partially turned down by the separating guide 54. The blade 56 further turns the fur down and insures that it is turned away from the skin edges of the strips The topof shoe 55, as previously described, acts as a guide to insure that the edges of the strips are evenly aligned at the proper height. As set forth above, the slots 55 provide play in sides "52 providing for the accommodation of strips of dififerent thicknesses and insuring that the edges of the strips are held close together for sewing.

It will, of course, be understood that the above described fur sewing machine is merely illustrative of the invention and applicant does not desire to be limited except as set forth in the claims.
