13 Claims.

This invention relates to ornamentation forming and feeding apparatus, and more particularly to an apparatus for automatically applying tufts,

tassels, and the like to the loops of looped headings used on drapes, curtains, and similar ar ticles.

One feature of this invention is to provide automatic means for forming ornamentation in which J the loops of a looped heading encircle tufts, tassels, and the like; another feature of this invention is to automatically feed the looped heading into a machine applying the ornamentation; still another feature is the automatic removal of the loops from the ornamentation forming m machine; other features and advantages will be apparent from the following specification and drawings, in which:

This invention is described herein in connection with a tassel forming machine, a device which is well known in the art. Such a machine is shown 50 and fully described in Walliser Patent No.

Thedevice described in Walliser Patent No. 1,663,534 is designed for forming tassels onfringe and loop heading material, and the like. ,In this 55; device the heading material is maintained in a fixed position while threads forming a warp are passed throughthe loop thereof. The warp is then cut and bound in the form of a tassel. In order to operate the Walliser device, it is necessary, however, to manually feed and. remove the '5" heading material from the machine. In our invention, we have obviated this and other difficulties by providing simple automatic means for feeding the heading material into the tasseling machine and removing the finished product 10 therefrom.

Broadly, our improved mechanism operates to feed loops or extension threads of a heading material to the tassel forming collar of the said Walliser Patent No. 1,663,534, whereby in the well 15 known operation of the tassel forming machine described therein, a tassel is secured to the loop as it is extended around said collar. Thereafter, by means of our mechanism, the heading material, loop, and the attached tassel are removed from the machine.

Our improved mechanism may also be used with other types of ornamentation applying machines such as the machine shown and described in the patent to C. F. Arnold, No. 1,390,267. In connection with the Arnold machine, our mechanism may be used to feed a looped heading to the forked die in which the tuft is formed and bound. In the construction of this invention as illustrated in the drawings and as seen particularly 30 in Fig. 2, A designates the tassel forming part of the Walliser machine; B designates our improved feed mechanism; and C the mechanism for the removal of the heading after the forming of the tassel. v

The tassel forming part of the machine is shown and fully described in Walliser PatentNo. 1,663,534 and need not, therefore, be described here in detail. It isbelieved to be sufficient to mention the main operating features and their cooperation with the other parts of our machine.

As shown particularly in Fig. l, the main drive shaft 20 driven by a motor or other suitable power means (not shown) in turn drivesthebevel gear 2| on' the shaft 22. At the opposite end of receive warp threads or other ornamentation therein. The nature of this device and its function is fully described in Walliser Patent No. 1,663,534. As therein stated, this collar is provided with a shoulder 32 which may be encircled by'a loop 33 of alooped heading 34. A strand of warp 35 may then be inserted in the collar and loop. The warp is severed above and below the collar. The projecting ends of the warp are then drawn together and bound by a wire 35 in the form of a tassel, as seen in Figs. 14 and 15.

The mechanism for forming the warp into a tassel forms no part of the present invention, being well known in the art and described in said patent.

The present invention is chiefly concerned with the mechanism for feeding and removing the looped heading and with the actuation of the arm 21 and collar 32 in cooperation with the tassel forming machine.

eferring to Fig. 5, the feed mechanism B is actuated by the shaft 20. 31. and 38 are mounted on this shaft. The frame 39 carries a pivot 40, on which is mounted the member 4|. The lower portion of the member 4| carries a round and horizontally projecting lug 42 adapted to engage the bevelled surface of the cam 31 rotating upon the shaft 20. An arm 43 is pivotally mounted on the upper portion of the member 4| and is secured in place by a pin 44. A coil spring 45, also mounted on the mem ber 4|, urges the rod 43 downwardly. A spring 46, secured to the lower end of the member 4|, urges the member towards the position shown in Fig. 5.

A member 41 is pivotally mounted on the arm 48 carried by the frame 39*. The lower end of this member is formed in the shape of a small cylinder 49, the side of which is adapted to be engaged by the bevelled surface of the cam 38. A spring 58, secured at one end to the member 4'! and at the other to a pin 5| on the frame 39, urges the member to the position shown in Fig. 5.

An extension 52 of the frame 39 carries a pair of bars 53 and 54 pivotally mountedin scissorlike arrangement on said extension. As shown particularly in Figs. 3 and 4, adjacent ends of the bars carry depending rollers 55 and 56. The opposite ends of the bars support pins 5'! and 58, the pins being provided at the upper ends thereof with annular bevelled grooves 59 and 65 adapted to carry a magazine rod or loop supporting memher 5 The ends of the bars upon which the pins 5! and 58 are mounted are normally held in adjacent relation by the spring 62. I

The member 4'! is equipped at its upper end with a projecting wedge portion 53, which is adapted to be received between rollers 55 and 56. The magazine rod or loop supporting member iil is mounted at one end in any suitable means, preferably a fixed means, from which it may readily be removed for loading, such as the clamp 54. The rod or member 6| is thus supported with a free end 96 adjacent the collar 32 when the latter is moved from the tassel-forming position. Said free end is cut away at 61 to provide a recess 91 adapted to overlap the collar 32, as shown in Figs. '7 and 8. Intermediate of its ends therod BI is, as previously stated, carried in the grooves 59 and 6!]. As seen particularly in Fig. 8, the upper surface of the rod 6| is provided with a series of longitudinal grooves 65 adapted to receive fingers or prongs E5 of the arm 43.

Two projecting, cams 4'! return to their original positions.

The operation of the feed mechanism is as follows. By opening the clamp 64, the magazine rod or loop supporting member 6| may be removed from the machine. Heading material is then secured to the rod by placing the loops thereon.

The rod 5| is then replaced in the machine and secured in position by the clamp'64 and the grooves 59 and 6|].

The rotation of the shaft 29 serves to move the arm 27 and the tassel forming collar 32 thereon in cooperation with the feed mechanism B. The

bevel gear 2|, the shaft 22, and the gear 23, all

driven by the shaft 25. in turn drive the gear 24, the shaft 25, and the cam 25. The roller 29, engaging the cam 26, causes the arm 21 to reciprocate horizontally about the pivot 28. The collar J2 is thus moved from tassel forming position, as shown in Fig, 2 and Fig. 9, to a position adjacent the guide rod 6|, as shown in Fig. 10, and upon receiving one of the loops 33 is returned to its original position.

The operation of the feed mechanism B in cooperation with the movement of the collar 32 is clearly shown in Fig. 5. The operation of the drive shaft 25 causes the cams 3? and 38 to rotate thereabout. The cam 31 strikes the roller 42, moving the member 4| to the position shown in dotted lines. In this movement the arm 43 travels along the upper surface of the magazine rod or loop supporting member 6|, drawing the loop 68 over the end of this rod. The prongs 85, moving in the grooves 65, prevent the arm 43 from slipping over the loop 58. As the cam 31 is moving the member 4|, the cam 38, by engaging the cylindrical extension 45 of the member 41, moves this member to the position shown in dotted outline. When the member 41 is moved, the wedge 53 is inserted between the rollers 55 and 55, spreading the pins 5? and 58 against the spring 62. This permits the rod 6| to fall to the lower position between the grooves 59 and 60, as shown in Fig. 4.

As shown particularly in Figs. 6, 7 and 8, when I the rod 5| falls to lower position, the cutaway portion 5? of the free end 96 is brought into juxtaposed relation with the collar 32 which, in the meantime, has been moved to position adjacent the end of the rod or loop supporting member 6|. In this position the recessed portion 91 of the rod 5| overlaps or telescopes the top of the collar 32. As a result, when the loop 68 is drawn over the end of the rod 5|, it must encircle the collar 32. v

When the cams 3'! and 38 pass the roller 42 and cylinder 49, respectively, the members 4| and The wedge 63 is withdrawn from the rollers 55 and 56. The grooves 59 and 55 are, therefore, brought together, raising the rod 6| to the position shown in Fig. 5'. The rearward movement of the upper end of the member 4| carries the arm 43 rearwardly along the upper surface of the rod 6|. The prongs 55 raise from the grooves 66 as they pass over the loop 68, dropping back into the grooves immediately thereafter. The collar 32, after receiving a loop, is carried by the arm 2'! to the position shown'in Figs. 9 and 2, where it receives the warp 35, and a tassel is formed.

The tassel removing mechanism C, shown particularly in Fig. 1, may be actuated bythe vertically bevelled cam 59 carried by the shaft 25. The frame 39 supports a bracket H, which furnishes a pivotal mounting at 95 for the member 12, which, in turn, is provided with an elongated cylindrical extension 13. adapted to engagesaid cam. A spring 12 secured to the. member 12, urges the extension 13 .upwardlyinto such engagement. A flat plate? is pivotally secured to the other end of the member 12 by the pivot it. The plate 14 carries on its upper end a removing arm 16 attached to theiplate by rivets H. A link i8 is attached at one end by a rivet 19 to the plate Hi intermediate of the ends thereof, and at the other end by a rivetiifl to a depending extension SI of the :pull rod 82. The pull rod 82 is slidably mounted. in the casing 83 carried by the frame 39. A shown in Fig. 2, the pull rod 32 is provided at one end with a lateral projection 84 attached to the spring 85, which is secured at its other end. to thecasing 83. On the other end of the pull rod 82 is mounted a roller 86 adapted to engage the cam 87. The cam 81 is mounted on the shaft 88 driven by the bevel gears 39 and 93. The bevel gear 90 in turn is driven by the shaft 9|, the, bevel gear.92, and. the shaft 23. The removing arm 16, as shown in Figs. 9 to 13, is equipped at its endwith a lateral extension 93 and a vertical projection 94. The lateral extension 93 is adapted to receive that portion of the loop 33 which connects the collar 32 with the heading material 34. When the arm 16 is raised, the extension 93 is thus enabled to lift the loop 33 from the shoulder 32 of the collar 32, as shown in Fig. 12. Thereafter, upon lateral movement of the arm 16, the projection 94 removes the loop 33 and tassel from the collar 32, as shown in Fig. 13. i

The operation of the removing mechanism is as follows:

The rotation of the shaft 25, driven by the gears 23 and 24, the shaft 22, the gear 2|, and the main drive shaft 20, causes the cam 69' to rotate. Wnen the cam 69 engages the cylindrical extension 13, the member 12 moves vertically shaft 29, is arranged to cooperate'in operation with the cam 69. The cam 81. permits the roller 83 and pull rod 82to be moved laterally by the spring when the recess 98 is engaged by the roller 83. The lateral movement of the pull rod 82 is then communicated to the plate 14 and arm 76 by, the link 78. Thus by proper arrangement of the cam 31. and cam 69,:the arm 16 is moved, first vertically, and then laterally.

As shown in Figs. 9 to 13, the successive vertical and lateral movements of the arm 16 serve to lift the loop 33 from the shoulder 32 of the collar 32 and then further separate the loop and heading material from the collar 32 by lateral movement. By using the spring 35 rather than rigid means to cause lateral movement of the arm 16,-

danger of tearing the ornamentation in the event the loop 33 should become caught on the collar 32, is obviated.

The rotation of the cams 69 and 81 is so arranged that when the loop 33 has been removed from the collar 32 the extension 13 is disengaged and theroller 86 is forced from the recess 98. The arm 16 is then returned to its original vertical position by the spring 12 At the same time the pull rod 82 and link 78 cooperate to move the arm 16 laterally to the original position shown in Fig. 11..

To summarize the operation of the machine, loops loaded on the rod or loop supporting member 6| are successively fed to the collar 32 by the member '43. As each loop is received by the collari32," the collar isreturned to tassel-forming position and a tassel formed thereon in the mane ner described in said Wallister patent. The loop is then removed from the machine by the means just described, and the collar 32 is returned to a position adjacent the rod 6| to receive another. loop.

While in the foregoing description we have set forth certain specific structures as illustrating our invention and described the same in connection with specific ornamentation applying machines, it will be obvious that many modifications may readily be made by one skilled in the art without departing from the spirit of our invention. For instance, in addition to feeding loops to'a collar member, the mechanism may be used for placing loops about or removing therefrom other parts of machines wherein different types of ornamentation may be fixed thereto. It will also be apparent that our improved mechanism may be used with any device wherein the automatic feeding or removal of loops is desired.

While we have illustrated and described a particular construction embodying our invention, we do not wish to be understood as intending to limit it thereto, as the same may be variously modified and altered without departing from the spirit of our invention. i
