MACHINE FOR MAKING TUFTS OR BUTTONS.

SPECIFICATION forming part of Letters Patent No. 440,708, dated November 18, 1890.

Application filed January 28, 1890. Serial No. 338,360. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM H. HUroII- INsoN and HARTLEY A. CABLES, citizens of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Machines for Making Tufts or Buttons, of which the following is aspecitication. i

Our invention rela-tes to machines for mal;- ing tufts or buttons; and it consists in certain devices for supporting and moving the bundle of yarn or stock, for applying the binder thereto and compressing the same, and for shearing the stock, as fully set forth hereinafter, and illustrated in the accompanying drawings, in which-n Figure l is a side elevation of an organized machine embodying our improvements. Fig. 2 is an enlarged view of the upper portion of the machine; Fig. 3, a section ou the line 3 3, Fig. l, the holder omitted; Figs. i, 5, and 6, sectional views illustrating the construction and operation of parts that act directly upon the stock and binder. Fig. 7 is a longitudi nal section of the jaws and operating appliances, illustrating a modification; Fig. S, a

' plan View of Fig. 7; Figs. 9 and l0, sectional views illustrating different forms of tufts; Fig. l1, asectional elevation showing a modiiied arrangement of the jaws; Fig. l2, an end View of the parts supported by the holder, looking in the direction of the arrow, Fig. ll. Fig. 13 is a detail of part of the actuating mechanism.

XVe will refer in the first instance to those parts of the machine which operate directly upon the bundles of fibers or stock to form the same into tufts, reserving for latter description the operating appliances which may be varied to an indefinite extent.

The main parts of the tuft-forming mechanism consist of the holder and feeder Y,

which supports the stock and feeds it at intervals, the binder7 WV, by means of which a suitable binder is applied about the stock near the end, and a cutter device7 Z, which The character of these devices will vary to a certain extent, according to the character of the tuft, and more especially of the binder that is used, the said binder in some instances consisting of a wire ring r, Fig. 9, clamped around the mass of fibers or stock, and in other cases of a fiat ring r, Fig. 10, separate or forming the flange of a cup. The eye in either case may consist of fibrous strands extending from side to side, or may be formed in any other manu er. The holder and feeder Y is provided with a head-stock H, secured to the frame of the machine and serving as a guide for a hollow slide L, closed at the end, with the exception of an opening a', constituting a short channel extending through a terminal boss Z, and opposite the latter in the headstock H is supported the die I. In the die l is a central opening y, in line with the channel as, to receive the boss Z, said opening contracting toward the outer face of the die, where it is of the same diameter as the channel and the front face of the die is fiat, forming a sharp cutting-edge a, across which shears the inclined edge of a reciprocating knife T, sliding in a guide 00, and opposite said knife is a slide 71., at the edge of which is a block of lead, leather, or other material 6l, against the edge of which the knife-blade may cut to secure a proper shearing action. By thus condensin g the stock to the plane of the knife-edge a and shearing directly across the latter and against a block of proper material the stock is cut.- clean across without any dragging or spreading the fibers, so that the end of the stock has a solid outline and will pass without dragging into the binder. By forming a short channel :c to receive the condensed portion of the fibers the friction upon the stock is less than when the condensing-channel extends the whole length of the slide. The binder r is supported by or between jaws, which hold it in position for the entrance of the stock, and then move radially inward, compressing the ring upon and into the stock. There may be two or morel of such jaws, and they may be supported and operated in any suitable manner, so as to receive between them the end of the stock and then contract the binder thereon.

IOO

As shown in the drawings, in Figs. 4 to 6 there are two jaws s, and in Figs. 7 and 8 six jaws, which may be made and mounted in different ways, but are preferably formed by slitting a hollow cylinder for a port-ion of its length longitudinally and radially, the remaining portion 5 of the cylinder constituting a carrier for the jaws, each of the latter having an outer beveled face 24,fhereby the jaws may be brought together by pushing upward a surrounding sleeve F, having a beveled mouth bearing against the inclined faces of all the jaws. In the forms shown in Figs. 4, 5, and 6, as well as in Figs. 7 and 8, the jaws are held normally open by a spring 26, which bears on the sleeve F and on thel carrier 5, as shown in Fig. 7, and tends to force the latter outward to the extent limited by the movement of a pin 27, extending from the carrierinto a slot 28 in the sleeve, and through thecarrier and between the jaws extends a bar 29, the outer end of which is formed in different-ways, according to the tuft to be made, but is shown in Figs. 4 to 6 with a recess le to receive the eye on a button-back when the latter is supported upon the bar between the jaws. The jaws are provided with inturnedlips 30, and the latter may have a groove or channel 3l in which to put a wirering binderrwhen desired.

In Figs. 7 and 8 each jaw has a side lip 62 extending into a recess 63 in the adjacent edge of the other jaw, one thus overlapping the other, so as to leave no space for the metal of the binder to pass into and preventing its entrance into the slots.

When a binder is to be applied to the stock to make a tuft or button, the said binder, whether in the form of a ring or a cup, is placed within the open jaws in the position shown in Figs. 5 and 6, and the stock is within the holder and feeder Y, as shown in Fig. 4. The sleeve F is now moved forward to carry the jaws toward the dieI until the outer face of each jaw is in contact with said die, when the slide L moves forward and the end of the stock is passed into or through the binder and held in that position. As the slide L continues its movement after that of the jaws is Aarrested,the ends of the jaws will be forced radially together, compressing the binder and forcing it into the mass of fibers constituting the stock. rIhe slide L is then drawn back to any desired extent, (the stock being held bythe jaws and ring, so that the slide slips over the stock,) after which the sleeve F and jaws are drawn out of the way and the slide L is thrown forward a partial stroke to the position shown in Fig. 4, and the stock is cut off, thereby completing the tuft, the slide afterward completing its stroke, so as to bring forward into the binder next applied a portion of the stock.

In the construction shown in Figs. 7 and 8 -the bar 29 extends beyond the end of the carrier into a slot 64 in the sleeve F and above a wedge-shaped bearing 32, which may be adjusted to diiferent positions by a screw 33, and the pin 27 extends through a slot 34 in the bar 29, so that after the movement of the jaws is arrested and after they are forced together to a certain extent the contact of the wedge with the bar 29 moves the latter with the sleeve F and forces the metal of the cup upward and i mparts to the same the conformation of the end of the bai' 29.

In order to operate the above-described parts in proper time by means of a treadle or other reciprocating device, we combine the said parts with others, constituting an operative machine, as illustrated in Figs. 1 to 3. In said iigures, A represents a part of the frame of the machine, which is shown as vertical, although it may be horizontal, and to which are secured the head-stocks H O in line with each other, and also the guides 60. To the frame is pivoted at 65 a treadle-lever M, and at 66 a lever N, which is connected with the slide L. The lever M is connected by a link 67 with the joint of two toggle-links 35 35, one pivoted to a bearing upon the frame A and the other to the end of the sleeve F, so that by swinging the treadle-lever in the direction of the arrow the toggle is straightened and thesleeve forced upward. AThe lever N carries a cam-plate P, the cams of which are suitably constructed and arranged to be acted upon by contacts carried by the lever M, so that as the latter swings to raise and lower the sleeve F the lever N also will bevibrated to first carry down the slide Land then raise the latter, and as the lever M swings back to its first position the lever N is moved to carry the slide L downward to an extent sufcient to project the stock the length required to form the tuft. The appliances for operating the lever N from the lnovements of the lever M may be varied; but we will now describe those which we have found to be eifcctive.

The cam-plate P is provided with two movable cam-ribs 4l 42, the rib 4l being pivoted at one end and adjustable at the other by means of a set-screw 44, and the rib 42 being adjustable at both ends by similar screws 44.

locking device in the form of a leverj, en-

gaging with astud 70 on the slide, is pivoted to the lever M, and serves to hold the slide in either position in which it may be adjusted.

The link 36 has a slot 71, Fig. 13, receiving a pin 72 on the slide, so that the link has a limited longitudinal movement independently of the slide, and this serves to carryastud 73 on the link along a U-bent slot 74 in the IOG IZO

lever j and to swing the latter into and out of position beneath the stud 70. Thus when the arm 37 of the lever S strikes the stop 39, the lever is swung to thrust down the link 36, which first by the action of the stud 73 swings the lever j in the direction of the arrow 2, Fig. .2, to carry the end from below the stud 70, releasing the slide K, which then moves down as the end of the slot in the link 36 makes contact with the pin 72. As the slide reaches its lower position, the stud 73 passes into the lower curved end of the slot 74, and the lever j swings in under the action of a spring 76 and again locks the slide. Upon themreverse movement of the lever S the slide is first unlocked, lifted, and then again locked.

As the lever M nieves in the direction of the arrow l, Fig. 1, the roller m traverses the lower edge of the rib 46 and forces out the switch 47 without imparting any movement to the cam-plate unt-il the sleeve F has been elevated to bring the faces of the jaws against the die I. The roller m then makes contact with the cam-rib 42, and thereby lifts the plate P andl vibrates the lever N sufficiently to carry the stock downward onto or through the binder, while the toggle is straightened and the jaws brought together. When the arm 37 of the lever S makes contact with the stop 39, the slide K is unlocked and forced downward, so that the roller m makes contact with the cam-rib 4l and depresses the rear end of the lever N and carries upward the slide L its entire stroke. As the lever M swings back, the roller 'm will make contact with the under side of the switch 47, thereby lifting the lever N and throwing down the slide L and feeding the stock forward to a limited extent.

The movements of the cutter and blade h are effected from a swinging arm U, connected by a link 68 with two crank-levers 69 79, pivoted to the frame and connected one with the cutter-blade T and the other with the blade h, as shown in Fig. 3. The arm U is vibrated by the contact of a roller g, carried bythelever M, with ribs 99 99 upon the arm. (Shown in dotted lines.) y j As the upper part of the arm M attains its rearmost position, the arm 37 of the lever S makes contact with t-he stop 38, and the lever S is vibrated so as to raise the slide K and lock it in its upper position.

When the machine is to be operated by power other than that applied to a treadle, it may be provided with a shaft and cams suitably connected With the parts to impart the desired movements at the proper times.

Although we have described the slide F as bearing against the inclined edges of the jaws as an effective means of closing the latter, it will be evident that other devices may be employed for imparting the radial movements to the jaws at proper intervals, and while we have described the jaws s as carried to andfrom the die l we do not limit ourselves to this arrangement, as the said jaws may be arranged in positions adjacent to the said die Vand capable only of radial movement imparted by a cam-ring V, having slots 80, receiving pins 71 on the jaws, as shown in Figs. 1l and l2. This particular construction we do not claim here.
