11 claims." (ci. zs--v This invention relates to the splicing, as opposed to knotting, of single strands of rubber known to the trade as' rubber thread.. The knotting of rubber thread is highly objectionable inasmuch as the knot acts as a slub in passing through guides` and needle hooks andl furthermore, in most instances, shows up as an imperfection in finished fabrics.
One of the objects of this invention is to effect a union of rubber strand ends which will be sufliciently strong so that these ends will not pul apart as elongation of the yarn occurs.
Another object of the invention is to join the 4ends without producing an obstruction to the functioning of the rubber yarn in fabrication Amechanisms in which the yarn may be used.

'knotting them, thus producing by such knotting an enlargement at the point of union which will 5 prevent the thread from passing freely through guides, needle eyes orA hooks which it is used for the formation of fabric. In order that the ends of such rubber or elastic yarn may be joined together. I have provided anl arrangement for splicing the ends without knotting and by rolling a thin adhesive film about the ends in such a manner that the ends are reduced and rin the finished product `no detrimental enlargement of the joinedy ends occurs, thus permitting the thread to be used in the usual manner fof fabrication andproviding a junction which is indistinguishable in the linished fabric; and the following is -a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished:
With reference to the drawings, I0 designates a casing or body portion' which is shown of a 23 suillcient size to be convenient to handle and some suitable material such las either metal or a plastic. This casing may conveniently be formed in halves, as shown in Fig. 12. The chief function of this body islto provide a convenient supi3 of the casing by a wall'll'which extends about I guide tiie lin feeder or apron about'the curvature of the track as it'moves therealong. These guides are open or stop short as at Il at the top of the device which enables the film feederto be removed from and replaced in the device. Bolts 2l secure the casing halves together. A cover il for the casing is hinged on the upper bolt 28 and` snaps into engagement with the which consists of a shell-like structure formed of l curved edge 22 of the casing by reason of a resilient lip 2l. The side walls of the casing project forwardly as at 23 and provide a pivotal mounting as by pin 24 for the slide holder designated This slide holder consists of a plate 26 having flanges 21 through which the-pivot pin 24 extends andalso provides in an enlarged portion thereof a mounting for the pin ,28 upon which the locking pawl 29, to enter an opening Ii, is pivotally mounted andswung in one direction by arm 30 of the spring 3l; while the' other arm 52 of the spring engages the flange 21. The pawl 29 is limited in its forward movement by engagement with the slide holder plate which extends beneath it as shown ati! in Fig. 5. The flange also supports the pin 3 3 which pivotally mounts the feed pawl 34 to enter an opening I6 on the other margin of the film feeder which has one arm 35 of the spring 38 forcing that pawl about its pivotal mounting; while the other .arm 31 of the spring engages the slide holder. A stop pin 38 limits the forward movement of the pawl 34. An eye 40 serves as connection for sp1-ing 4I which is anchored as at 42 in the casing to swing the slide holder about its pivot 24 to the position shown in Fig, l. The slide holder also has in it slots 43.
The slide. is designated generally -45 and consistsof a plate 45 which has, shouldered bolts 41 fastenedinto the plate'with portions 48 slidable in and guided by the slots 43 andjheaded to extend over the`slide holder so as to form an effective guide for vertical movement of the plateA with reference to the slide holder.- This plate is cut away atits upper end to provide an anvil 50 55 -of-a stub shaft 56 formed between shoulder 90 which receives. the jaws.
The shaft is received in a recess 9| in the plate and the shaft handle 51 is secured by means of set screw 58. A stop pin 59 is located between the jaws below the cam so as to limit the opening movement of the jaws. The jaws are swung to open position by a bow spring 50 which extends about the cam and shaft with its ends l engaging the upper portions of' the jaws below cutting edges 52 which are provided to engage the opposite sides 53 of the anvil 58 to move the jaws against the anvil and sever -the yarn which may be positioned be-' tween the anvil and the jaws. s
On either side of'th casing, supports 85 are provided in which there are mounted yarnholders 58 consisting'of bristles. extendingupwardly therefrom which serve to effectively frictionally retain the rubber yarn in the operation of the device. These.yarn holders maybe adjusted as. to 'position by screws 88 serving to placed through bristles 81', thence across the face of the anvil 12 between the opposite side of the anvil and the opposite cutter 5I and then through the bristles 81 of the other yarn holder. The bristles provide the proper degree of tension in the yarn which may be-under some little elongation. The yarn is now loaded into the device for operation thereof. The handle 51 is grasped i in the other hand, and turned enough to bind but not sever the yarn, andthe slide holder swung to. move the yarn across the face of the anvil into engagement with the film 80 on the film feeder, and, as this motion occurs, the handle 51 will be rotated to cause the cam 55 to move the jaws or nippers to cut the yarn between the cutting edges of the nippers and the anvil. Also,
film upward. Thus, when the face of the anvil engages the film 88, there will remain on the face of the anvil only portions of the yarn overlapping each other the width bf the anvil. Also,
when this engagement occurs, pawl 29 enters the hole I5 on the other margin of the lm feeder and locks it against further movement. Then, by lifting the handle and moving the slide` upwardly, the overlapping portions of the yarn at 13wi1l cause the-film to vbreak as at 8l, and will roll that portion of the film 82 aboutthe overlapped portions of the yarn and about veitherside thereof as at 84 (see Fig. 9) s o as to provide a spliced joint, while Athe overlapped portions are in Acompressed relationship. The upward movement will be'suicient to wrap this film one or two revolutions about the overlapped portion 13 and then by reciprocating slide downwardly and upwardly one or vtwo times a very firm union occurs and a splice results such asdesignated as at 14, as shown in Fig. 11.
The length of movement of slide is such that the distance the pair o f threads rollalong film feeder I5 is greater than the distance said lm feeder moves in the feeding operation. This in-v sures the-complete utilization of the amount of rubber film supplied to the threads in such film- Ifeeding operation.

2.In a splicer, a carrier for a thin film of material, a iilm carried thereby, means for holding the thread and severing the same to provide portions in overlapping relation, said means being Assuming that I wish to -splice two end portions v V1li, 1I 'of rubber yarn, I will place the end portion 18 through bristles 81, thence along the face 12 of the anvil. between side 83 of the anvil and the cutting jaw 5| and thence through the other mounted forl movement to roll the overlappedends of thread'.

then by moving the slide, roll the film about the overlapped ends.
5. In a splicer, friction means for retaining the end portions of thread in proximity to each other, means for severing the end portions while retaining some portions in overlapping relation, a carrier for a thin lm of material, a iilm carried thereby, and means for moving said overlapped end portions of the thread into contactwith said lm. and rolling the end portions to wrap the iilm about said overlapped end portions.
