My invention relates to chenille-making ma chines and more particularly to improved means for carrying the pile-forming strands. In machines of this type and particularly those used for making tinsel of the type used for deco rating Christmas trees and on other festive occa sions, it is the usual practice to provide each (01. 57—-24) 2 ‘rially altering the structure of such machines, while permitting such machines to operate for relatively long periods of time without the neces sity of interruption for re-spooling. This and other objects are'attained by my in vention as set forth in the following speci?cation and as illustrated in the accompanying drawings, in which: Fig. 1 is a fragmentary top plan view of a con machine with two separate heads, each of which, in the more improved machines, forms two “ropes” of tinsel. The tinsel is formed from rela 10 ventional chenille-making machine of which only tively thin strands of metal foil which are twisted the parts necessary for illustrating the invention and looped on and between strands of yarn, the have been shown. loops, being then cut so as to produce loose ends Fig. 2 is a view partly in section and partly in which extend at an angle to the supporting or core yarns. In order to give the tinsel a thick, 15 side elevation, of the machine shown in Fig. 1. Fig. 3 is an end elevation taken on the line ?uify appearance, it is desirable to use a large III——III of Fig. 2. number of ends or strands which are fed simul Fig. 4 is a plan View of the forming bar which taneously. However, since machines of this type is part of the conventional machine. are long and narrow, and since it is the practice Fig. 5 is a section on line V—V of Fig. 4.. to provide each machine with two spinning heads so as to produce two “ropes” of tinsel simultane ously, there is no room for accommodating two In Fig, 1, there is shown a source of power, such as a motor M, which drives a shaft 5 which heads, each of which is large enough to carry the required number of spools. It, therefore, has been the practice heretofore to take several spools of tinsel strands, for example four, each containing a predetermined number of feet of strand, as, for example, one hundred feet, and to rewind the strands from all four spools onto ‘carries a gear 7. The gear ‘I meshes with ring a single spool of the same size. The result is that the single spool referred to carries only gears 8 which form part of or are carried by each of two spool-supporting heads 9. Alternately, the spool-supporting heads 9, instead of having ring gears 3, may be provided with grooves which will be engaged by a belt driven by the motor M or other source of power. The heads 9 are car ried by sleeves H! which are mounted on stub shafts I I and provided with suitable thrust bear twenty-?ve feet of “ll-ply” tinsel strands. When iIlgs Q. When the heads 9 are rotated by the this practice is followed, it is necessary to stop gear I, the sleeves l6 also rotate On the stub shafts H. Each of the stub shafts ll carries a forming bar l3 which is provided with radial and respool the machine as soon as the twenty ?ve feet of 4-ply strands have been used up. This, together with the necessity of winding the 35 grooves 14 and above and below which are suit- ' ably mounted rotating cutters IS. The textile strands from several spools onto one spool, re tarded production and increased costs. This problem has heretofore been recognized yarns about which the tinsel yarns‘ are twisted, together with the guide wires forming part of and an attempt to solve it is disclosed in Ander conventional machines of this type, have been narrow and there is no room for enlarged spool spools which carry the tinsel strands are mounted on the left-hand side of the head, as viewed in tion to produce an improved supporting head whereby a greatly increased number of spools may be supported without increasing the size of 50 about the forming bar and are cut by the cutters son Patent No. 1,585,357 of May 18, 1926. In 40 omitted from‘ Fig. 2 for clarity of illustration. The sleeves II] are provided with rods l6 which this particular patent, the solution of the prob carry a guide ring 11 which rotates with the lem consisted in providing a greatly enlarged head sleeves Ill and the heads 9. for supporting the spools and by mounting on conventionally, and as illustrated in the patent said head concentrically-staggered rows of spools. This, as above stated, is not an adequate remedy 45 above referred to and such other patents as Wolkow, No. 1,039,876, of October 1, 1912, the because machines of this type currently used are heads. It is, therefore, a speci?c object of the inven Fig. 2, and the strands from the spools are twisted I 5 above and below the bar. The textile yarns about which the tinsel strands are twisted have been omitted from Fig. 1 also, but the guide wires, the head itself, so that conventional machines may be equipped with two heads without mate 55 which serve to propel the work to the left, as viewed in Figs. 1 and 2, are shown at 16X in Fig. 2,408,898 3 1, as are the guide rollers I8 over which these wires are endlessly driven. As will be seen from Fig. 1, the guide rollers I8 are in the nature of grooved pulleys which overlap the opposite edges a single strand, it follows that each of the thirty two spools carries a, much longer strand of tinsel than would be the case when two or more spools are re-wound on a single spool to provide two, three or four ends on one spool. For example, of the forming bar. The parts heretofore de Or if in prior conventional machines, the spool head scribed may all be conventional and form no part is provided with sixteen spools, each of which carries two strands, so as to produce a tinsel rope of the present invention. In order to carry out my invention, namely, to formed of thirty-two ends, such machine will avoid rewindlng two or more spools carrying run for a period of time equal to one-half of the 10 tinsel strands onto one spool and thus shorten time for which a machine provided with a head the operation of the machine between re-spool embodying my invention and carrying sixteen ings, I have devised the head shown best in Fig. spools on each side will run. In other words, the 3. As will be seen from this ?gure and from the conventional machine referred to has to be re other ?gures of the drawings, I have'mounted a spooled twice, every time that a machine em 15 number of spools 20 on opposite sides of the bodying the head of my invention will have to head 9, the spools on one side of the head being be re-spooled once. This increase in the length preferably staggered with respect to the spools of time of continuous operation of the machine on the other side thereof. Each of the spools constitutes a very great saving in time and labor 20 is mounted on a stub shaft 2| and is tensioned and, because the spools are located on opposite by a spring 22. To One side of the head 9, I pro 20 sides of the head, the overall dimensions of the vide an auxiliary head 23, which is provided with head will not be increased. Therefore, a con apertures 2:1 which register with apertures 25 in ventional machine, such as that illustrated in the head 9 and through which the tinsel strands Fig. 1, instead of having two, heads each having 26 from the spools on the corresponding side of eight spools with four strands on each spool, with 25 the spools all on one side of the head, will, ac the head are adapted to pass. As will be seen from Fig. 2, the strands 26 cording to my invention, have two heads each of from the spools on the right-hand side of the which has sixteen spools, thus providing the same head 9 are guided by the ring I‘! onto the form number of ends without enlarging the machine ing bar 13, while the strands 21 from the spools or materially altering the arrangement of the on the left-hand side of the head impinge directly 30 operative parts thereof. upon the forming bar. As the sleeve III, the head What I claim is: 9 and the auxiliary head 23 rotate, the strands The combination with a tinsel making machine 26 and 27 are twisted 0n the forming bar and of a spool head for supplying strands of tinsel are cut by the cutters I5 to form multiple ropes to the forming bar of said machine, said head 35 comprising a relatively small body of a size to of tinsel 28, as shown in Fig. 1. As shown in Fig. 3, the head 9 is provided with ?t the dimensions of a conventional machine eight spools on each side thereof, making a total of this type, a ?rst plurality of spools on one of sixteen. This, however, is simply for the pur face of said head,_a second plurality of spools pose of illustration, because in actual practice disposed on the opposite face of said head in and on an actually-operating machine, there are staggered relation to the ?rst mentioned spools, sixteen spools on each side of the head 9, giving and a plate rotatable with said head and having a total of thirty-two spools, all of which feed apertures therein for‘ passage of strands from strands of .tinsel simultaneously to the forming said second plurality of spools therethrough, bar [3. By this means the tinsel is formed from there being apertures in said head registering thirty-two separate ends, so that it has the de 45 with the apertures in said plate for passage of sired thickness and ?uf?ness, but, since all strands from said second plurality of spools in thirty-two spools are original spools, that is, each the direction of the strands from the ?rst plu of which carries a single end, it follows that the rality of spools. machine will run until the tinsel strands on the spools are used up. Since the strands of tinsel 50 are extremely thin and since each spool carries JOSEPH WILMSEN.
