This invention relates to apparatus; forf'pi'oducing threaded spangl'es, that is, threadsof spangles in which the individual span'gles are arranged and secured on a thread in 'flatwise position thereon, that is, with the opposite faces of the spangles lying against adjacent parts of said thread. g v

This invention is concerned primarily with a meansfor feeding the spangles and the string on which they are strung to the machine which arranges the spangles in said flatwise relation and which secures the spangles in said relation. However, the machine itself, which for convenience in reference will hereinafter be designated as a spangling machine is known to those skilled in this art.

For convenience in handling, spangles which are to be arranged as indicated above fiatwise on a string threaded therethrough are first mounted on supply strings in adjacent'face to face relation co-axially on their respective strings which are threaded through the spangle apertures, one supply string carrying say about two yardsof spangle's. In accordance with the present invention, the spangles are transferred from their'supply strings to the string on which they are to be secured'flatwise in the finished product. More particularly, pursuant to the present invention the spangles are disposed in freely movable relation on a string threaded through the. apertures of said spangles, and since in thefinished product the spangles are disposed .flatwise on the string to which they are securedand which is threaded therethrough, the string must be of considerable length. For example, when eight yards of spangles are disposed on the supply strings in co-axial relation adjacent to each other, in the finished product wherein, the spangles are disposed flatwise, the length of the string. must be about 160 yards for spangles which areabout of an inchin diameter presupposing the normal flatwise disposition of the strings. with the faces of adjacent spangles in slightly overlapped relation, as they usually are in the finishedproduct. It will be understood that this long string must be passed through the apertures. in thespang-les and fed into the spangling machine together with the spangles at the proper speed, By the present invention provision is made for feeding the string and the spangles through which the string is threaded to the spangling machine in a greatly improved and advantag'eous manner. This constitutes one of the objects of the presentinvention. Y

In fee ng the span'gles to the spangling Inathe apparatus;

chine, a number of 'spangl'e's are positioned adja' cent the intake of the machine in position to be moved by gravity into the machine. If too many spangles are disposed at theintake of the ma chine the weight of said spangles interfereswith the proper operation of the machine and'ther'e sulting product is frequently defective. This objecticin and disadvantage is eliminated in ac"- cordance with the present invention by providing means for limiting the number of spangles adjacent'the intake of the machine. I

The above and other objects of the machine -will best and more fully beju'nclerstood from the following description considered with reference to the accompanyingdrawings.

. Fig.9 is a View of the other side of the string of spangles' shown in Fig. 8. Referring now to the drawings in detail, a multiplicity of the 'spangles 1'0 are arranged "coaxially on part of a string l2 in freely movable relation thereon, said string being threaded through the apertures of said span i'e's. Said string is ,of great length compared to the combined thickness of all of the sp'afigles through which Said'string is threaded and is, therefore, for convenience wound foh a spool M as shown in Figs. 1,5 and 6, said string forming part (if the spangle-feeding apparatus illustrated in said figures of the drawings and also in Figs. 2, 3 and fl. It will be understood that the spangle's are initially furnished on supply strings, in lengths of say abo'uttwo yards of "spaifigleaafid that said span ies are transferred to rxidunnsg string string.

guide rollers, particularly guide roller 22, being i mounted in elevated position above the intake I9 of the spangling machine, the arrangement'being such that string I2 slopes downwardly from said elevated position thereof to the intake of said machine. String I2 is drawn through the machine at the proper speed by the take-uproll 24 on which the finished string of spangles is wound, said take-up roll being driven by a pulley 26 in timed relation to the operation of the machine. Spool M is provided with a braking. device and forthat purpose has a grooved section 28 in fixed relation therewith which is engaged by a tensioned cord 39. One end of said cord is fixed tothe standard as indicated at 34, and the other end' of said cord i fixed to one end 36 of a metal link 38, the opposite end 40 of which is pivotally secured to support 35. End 36 of link 38 is connected to a weighted roller 42 which is 5;

supported on thread I2, the weight for said roller being indicated at 44. Additional weights 46 and 48 are connected to the end of link 38 and at a point intermediate said ends. The devices just described provide convenient means for tensioning string I2 and for preventing the free rotation of spool It on the spindle, but any other suitable string tensioning arrangement can be used instead. 1

The spangles H] disposed on string l2 move downwardly thereon over a downwardly inclined guide and support 50 mounted on vertical supports 52 and 5,4. Said guide and support'5ll is as here shown in the form of a trough having opposite side walls 56 and a bottom 58. Side Walls .1

5S constitute guides for string I2and bottom 58 serves to support the spangles carried by said The spangles thus. move toward the 'spangling machine partly by gravity and partly by the string on which, they are carried,' the movement of said spangles being retarded by the frictional engagement of the upper surface of the bottom 58 of the chute with the spangles, .A roller 63 is positioned near the lower end of guide 50 and is rotated by a pulley 62 for assisting the movement of the spangles at the lower end of said guide. String I2 and the spangles I9 thereon also pass over a roller 64 driven by apulley 66. From roller 64 the spangles IE] and the thread I2 pass to the inclined guide chute 68 of the spangling machine it; and from said guide to the intake I 9 of the machine.

As stated above, one of the objects and features of the invention is to prevent the accumulation of spangles 0n guides 88 in such numbers that the weight of the spangles would interfere with the operation of the machine. For this purpose provision is made for automatically interrupting the movement of spangles on thread I2 .to supply guide chute 68 of the, spangling machine. The means provided for accomplishing this result includes a barrier iii disposed at the lower end of guide 56 adjacent roller 64. As here shown said barrier 16 is in the form of a forked member which is positioned so that the crotch I2 thereof I2 by attaching the end of the latter to the supengages the spangles on string I2 and prevents movement of said spangles to guide chute 68 of th machine. barrier I0 does not prevent movement of string I2 and that consequently the latter moves continuously so long as take-up roll 24 is rotated by the machine. Y rendered ineffective to prevent movement of the spangles to guide chute I58; For this purpose roller 64 is provided with a member I4 fixed to said roller in position spaced radially from the hub I6 thereof. During each revolution of roller 64 member I4 engages string I2 and raises said string above hub I6 of the roller to an elevated position such that the spangles slide down the string over and past the crotch of barrier ID to the guide chute 68 of the machine. Thus groups of spangles I0 are supplied intermittently to guide chute" 68 of the spangling machine and the arrangement is such that the number of spangles on the guide chute 68 at any one time is insufii- ,cient to interfere with the operation of the machine; Fig. 2 shows the position of roller 64' and more particularly member I4 thereof for eleva'ting the string I2 so that the barrier is rendered ineffective to prevent movement of spangles to:

spangles to the guide chute but, as stated, permits the string to pass freely over the crotch of the barrier to thespangling machine. It will be observed that roller 64 is driven in timed relation to the operation of the machine I and for that purpose the pulley 66 of said roller I is connected by a beltlil to a pulley which is driven by the shaft which rotates roller 60 and which is driven by pulley 62. A belt 82 connects pulley 62 to a driving pulley 82 which is fixed to and rotated by a shaft 84. Said shaft is driven by the main shaft 86 of the spangling machine and is connected by a belt 88 to the driving pulley 26 of the shaft which rotates take-up roll 24.

As stated above, the spangling machine I6 is of known construction and operation and therefore requires no detailed description. It will be understood also that said machine. is supplied with strings of thread which secure the spangles in flatwise position on string I 2 which is threaded and 94, respectively, being twisted in opposite directions about the thread 90a which is supplied frorn spool 90 and about the thread I2 which is threaded through the apertures of the spangles. Thread 90a is thicker than threads I2 and threads 92a and 94a and is disposed with said last mentionedtwo threads 'as illustrated in Fig.9 on one side of the string of spangles, the other side of the string of spangles having, as illustrated in Fig. 8, only thread I2 disposed thereon.

Thus, it is seen that the apparatus of the present invention is well adapted to accomplish the several objects 'thereof. It will be understood that the downward slope of the string on which the spangles are carried to the spangling ma- It will be noted, however, that The barrier Ill is intermittently pursuant to the present invention, the distance from roller 22 to the intake of the machine is about 34 feet, said roller is at a height of about '7 feet, roller 64 and barrier 10 are about 3 feet below roller 22 and about 2 feet higher than the intake i 9 of the spangling machine and at a distance of about 2 feet laterally of said intake. It will be understood, however, that these dimensions, while preferred, have not been established as critical and are not to be considered as limitative but only illustrative of the best mode of which I am now aware for practicing my invention.

Accordingly, while I have disclosed the presently preferred embodiment of my invention, it will be understood that the invention may be em bodied otherwise than as herein specifically shown or described and that changes may be made in the various partsof the apparatus and in the arrangement thereof. Therefore, I do not Wish to be limited to the embodiment of the invention here shown or to the specific construction herein disclosed as embodiments of said invention except to the extent which may be required by the scope of the appended claims.
