BUTTON-ATTACHING MACHiNE.

SPECIFICATION forming part of Letters Patent No. 389.237, dated Eieptember 11, 1888.

Application filed December 9, 1887. Serial No. 257,471.

ject is to facilitate this operation by the use of apparatus which shall automatically form the fastener and attach the button.

The invention consists in the novel construction, combination, and arrangement of mechanism for this purpose, as hereinafter set forth and claimed.

Similar letters of reference indicate corresponding parts.

This machine is designed to form from continuous wire and within the eye of the button a fastener, press the point or points of the same through the leather or fabric, and form on the under side a suitable eye or loop, which, when finished, lies flat against the leather or fabric. The mechanism through which this operation is performed admits of considerable modification in form and coir struction, some of which modifications are shown in the accompanying drawings. Apparatus fully illustrating the principles and operation of the invention will now be described.

A is a bed-block mounted on a suitable frame, M, which is preferably made high enough to bring the bed-block to within easy reach of the operator. A cheap and simple frame is made of wood in the manner shown in Figs. 1 and 2, and this is preferably mounted on a suitable iron base, M, said base and the bed-block being connected by bolt-rods M.

The frame M thus serves as a casing for the internal parts of the machine. On suitable brackets, L L, attached to this frame, is mounted the wire-spool L. To this base M is pivoted a foot-lever, H, and to the inner arm of the lever, by suitable connections, are pivoted rods D, E, and F. It is not absolutely necessary that there should be more than the one rod D connecting with the footlever, as the others may branch from that, as indicated by the construction shown in Fi 13, where the arm F is made a branch of the rod E. The construction shown in Fig. 1 is, however, more suitable to thesimple form of the machine shown in the first two sheets of drawings. It is desirable to bring the pedal of the foot-lever comparatively close to the machine; and so, in order to get the requisite leverage, i connect the lever to a pivoted arm, G, and this to the foot of the rod D. The others may be connected directly to the inner arm of the lever, as shown.

In the upper end of the rod D are set the off to the point of attachment.

S, connecting with the rod D, and by suitable central core Q over which the staple is bent dies which form the finish of the fastening on the under side of the leather, and which will be hereinafter more particularly described. In the upper end of the rod E is the wire-cutter E, and the rod F terminates at the upper end in means for actuating the wire and button feed, which will also be hereinafter described in detail.

Within the bed A is mechanism forforming the staple from which the complete fastener is made. This device consists ofa plunger, QQ, adapted to catch the piece of wire as cut off on its forward end and thrust it forward to the point of attachment. In its passage the wire is pressed between the sides of a bellmouthed former, no, on the under side of the forwardlyprojecting horn of the bed A. This feature of the invention admits of considerable variation in construction, the principle being the formation of the staple by the forward movement of a plunger adapted to carry the piece of material of which the fastener is made from the point where it is cut The device illustrated in Figs. 8 and 15 shows a simple and efficient manner of performing this operation. The plunger is made of two principal parts, Q Q, hinged together. The shank of the part Q is a round shaft mounted in and adapted to slide endwise in suitable bearings formed within the bed A. Its mate Q is hinged to it in the simple'manner shown in Figs. 4 and 19, a helical spring, 8', serving to automatically spread the staple-forming wings of the plunger to the horizontal. These wings in the forward movement of the plunger pass between the sides of the bell-mouthed former r r and are gradually turned by a spiral movement to the vertical, as shown in Fig. 6. The plunger is actuated by means ofa bell-crank,

connecting-rods, R, with a sleeve, m, loosely mounted on the shaft of the plungef between two fixed collars, ZZ. A powerful spring, T, forces the plunger forward and the downward pressure of the foot-lever carries it back.

In the device just described the staple 2 is formed around the reduced end of the wings n 'n, the outer sides of the staple bearing against the inner sides of the former M. The shoulder near the ends of these wings is made at right angles to their length. Oonsequentl y when the staple is finished it stands vertical, with the points down. The same result may be effected by forming the staple between the wings a n, as illustrated in Fig. 14, in which case thedevice is preferably provided with a by the passage of the wings between the guides r r.

A further modification is shown in Fig. 16, in which the staple is formed by simply thrusting the wire straight forward through a bellmouthed former, r 1", by a single plunger, Q, in which case the staple would naturally be horizontal when finished. As means may be easily devised for righting the staple should its own gravity be insufficient, this device may serve the purpose in view.

As the plunger cannot remain at the forward point during the attachment of the fastener, I provide means whereby the staple is held securely in an upright position during this operation. It will be understood that previous to the formation of the staple the wire to has been fed through the eye of the button Z. In its forward movement the shank of the button passes along a slot in the middle of the born A, the slot being but little wider than the thickness of the shank, so that the sides of the button lie above a thin flange of this part A.

- This would, of course, be sufficient, ordinarily,

to prevent displacement of the button at any time; but to insure the proper position of the staple under all circumstances I provide these flanges with a notch, t, on the under side at the point where the staple stops in its forward movement, and by means of a spring, 8, under the button draw the loop of the staple into this notch. The notch not only serves to right the staple in the first place, but affords a secure bearing for the loop during the formation of the fastener.

The apparatus for thrusting the staple through the leather or fabric and completing the formation of the fastener is shown in Figs. 6, 7, 8, and 10, and also in Fig. 2. Referring to said Fig. 2, it will be observed that the rod D is composed of two parts, and between these parts lies the rod D. The latter is arranged to have a limited movement vertically between the parts ofD, and is pressed upwardly by a powerful spring, D, bearing at its lower end on a transverse portion of the part D and at its upper end against a collar on the part D. The sides of the rod D are made slightly flexible, and are so constructed that their natural tendency is to spread apart at the upper end, which passes through a suitable hole in aforwardlyprojecting portion of the bed A. To the up per end of each part is secured a die, 19, the lower end of which die forms an angle and projects out from the part D. A corresponding angle is formed in the upper side of the block A, so that as the rod D rises the parts are spread when the bottom of the dies 1) p reach this angle in the block and are correspondingly drawn together as it descends. The upward motion of these dies tends to form the eye, loop, or coil on, the lower end of the fastener, and the outward motion to spread the legs oft-hesame apart in the operation of clinching, as will be evident upon a reference to the dotted lines in Fig. 6.

As before stated, the machine is more specially designed to make a fastener, the ends of which are turned into an eye or coil and then bent flatwise against the material to which the button is secured. It is evident, however, that it may be used in connection with other forms of fasteners, the construction of the die being varied to suit the circumstances. Thus in the case of afastener made by spreading the prongs of the staple simply the dies may be single ITO and little more than a flat piece of steel with slight concavities in the top for the points of the staple, according to a common and wellknown construction. In the application of the machine to the formation of my style of fast-- ener, however, special means are required.

The first part of the operation is to force the points of the staple 2 through the leather or other material, 3. It is desirable that this should be .done somewhat in advance of the turning of the eyes on the ends of the staple, and I therefore prefer to use a separate die for that purpose. This die 0 is set in the upper end of the central rod, D. It is preferably made H-shaped in cross section, the central web, 0, correspondingin thickness to the space between the prongs of the staple. The outer dies,pp, are fitted to the channel between the lateral flanges of the die 0 and are free to slide therein. To deflect the points of the staple, I provide the die 0 near its upper end with a laterally-projecting pin orlug. 0,which strikes the prongs of the staple on their beveled sides, respectively, and bends them out wardly in the opposite directions indicated in Fig. 10. The points of the staple striking the inner sides of the flanges of the die are then deflected inwardly, and the eye is thus partially formed by this central die. The outer dies, pp, then moving upward come in contact with the unfinished coil and complete it, and with the final movement spread it sidewise, as already described. The upper side of the lateral lugs 0 may project outward considerably; but the under side should be beveled to allow for the movement of the outer dies in completing the fastener. The central die is carried upward by the general upward movement of the rod D; but, being connected to the rod D by a spring, as before stated, it may move in advance of the outer dies until it reaches its terminus, when the spring yields and allows the outer dies to finish the work.

A modified form of dies which dispenses with the central one is shown in Figs. 17 and 18. In this case the dies 0 0 are hinged to gether at the upper end, and are separately hinged to the upper ends of the rods D D. The eye or coil of the fastener is formed by the single die 0 by the straight upward motion of the same to a certain point, when the rods 1) I), being liberated, are free to spread apart, correspondingly spreading the lower part of the fastener, as indicated by the dotted lines in Fig.17.

The buttons are fed to the machine through a chute, N. This may be automatic, as illustrated in the principal figures, or a chute filled by hand, as shown in Fig. 20. In its simplest form it consists of a tube, N, a little larger than the head ofthe button inside, and with a groove in one side a little wider than the shank of the button in its widest diameter. Parallel with the tube and along the center of the groove lies a wire, a, upon which the buttons are strung, and which serves to keep them in uniform position. The chute may be connected with the top of the bedblock A by a simple dovetail connection, N, so simple as to require no further description.

In practice it is desirable to make the ma chine so as to supply the chute automatically and render it capable of being used in connection with the one or the other at will. It is also desirable to have more than one automatic chutethe one for bright and new buttons and the other for old ones-and to so construct the machine that the one or the other may be connected at will. In Figs. 4 and 5 is shown a single automatic bnttoufeed, and in Figs. 11, 12, and 13 a double one, the machine being also adapted to operate in connection with a handfilled chute.

The chute for the automatic machine is constructed in substantially the same manner as for the one above described, with the exception that the wire a is not connected to the chute at any point, and the chute itself is preferably semicircular in form, as shown. It is secured to the machine by an arm, 0, of the standard 0, and the upper end of the wire (t communicates with the interior of a drum, B, containing a quantity of buttons, Z. This drum is provided with buckets B inside, and. is mounted to revolve in a suitable bearing at the upper end of the standard 0. Motion is imparted to the drum by means of a rack, F, connected with or forniinga part ofthe rod F, and a pinion, (I, having a suitable pawl therein adapted to engage with notches in the journal of the drum. \Vithin and above the centerof this drum I mount a hopper, 13, converging at the lower end to an opening something larger than the diameter of a button. This hopper is supported from and by a cylinder, P, passing through a hollow hub, B, of the drum, and this is in turn secured to an up weirdly-extending arm, 0, of the arm 0. Through this cylinder the wire a passes in the inclined position indicated, and at the inner end turns up vertically under the center of the hopper B and terminates in a point to facilitatc the attaching of button-shanks thereon. The elevator-buckets of the drum are preferably niade somewhat rounding on the under side, so that in discharging they tend to converge the buttons toward the center of the hopper, though this is not absolutely neces sary, as in the operation of dropping the buttons through the hopper some of them will catch on the wire.

. The wire a is supported near the npperend, preferably at three or more points, by a series of grippers, c, c, and c. The first-mentioned gripper, c,is preferably mou ntcd horizontal and at right angles to the vertical portion of the wire. The others operate at a right angle, or nearly so, to the inclined portion of the wire passing through the cylinder 1. The construction of the grippers is shown in Fig. 11. They consist, essentially, in a pair of rings arranged side by side, and terminating ontwardly in shanks adapted to slip cndwise in suitable bearings and inwardly in an angular portion adapted to centralize and tightly hold the wire. Springs 6 e etend to draw the rings toward the wire, and cams b Z) Z) inside the hub B to force them in the opposite direction. These cams are preferably arranged at different points in the inner circumference of the hub, so that the operation of the grippers is alternate, two holding while one is open. The opening of the rings allows a button to pass through, and on the passage of the cam the spring throws the gripper back to its normal holding position.

The inclined position of the wire a is calculated to keep the shank of the button upper most until it shall have passed themouth of the chute N, when its position is positively controlled; but in the event that a button should get wrong side up its position is reversed by the curved extension of the upper end of the chute N. Buttons may be poured into the drum through the pipe 0, communicating with the hollowjournal of the drum.

The lower end of the chute communicates directly with a device which may be designated as the button-table,sinceit is on this that the button rests while the wire to is being fed through its shank. The construction of this button-table is shown in Fig. 9. It consists of a thin plate, h, having a portion turned upwardly to connect with the spring is, Fig. 5, said'platc being rectangular, with a notch cut out of one corner. In this corner is placed a corner-piece, h, smaller than the notch in the plate h, and connected to the larger part by bridges h lt. The channel formed by the separation of the bottom parts of the table is under the bridge h wide enough to admit the shank of the button sidewise and under the bridge It to allow for the exit of the button-shank edgewise. It will be readily seen that a button passing under the bridge h' from the chute will stop in the center of the table and can only pass out at a right angle to the line of entrance.

In its normal position the button table is too high for the passage through its shank of the wire to form the fastener; so it'is necessary to cut out this button from the rest of the row and drop it below the others. To this end a suitable hole is made in the top of the bedblock A, and at the proper time a presser, f, actuated by the same mechanism which governs the feeding of the wire 10, forces the table down and holds it in that position until the wire has been fed, through the shank of the button. A simple actuating device for this purpose is shown in Fig. 5, the outer arm of the presser engaging with a notched wheel, I, connected with or forming a part of the wirefeed roller I. On the release of this outer arm of the presser the inner end flies up by the ac tion of a spring, j. By a suitable adjustment of the respective parts of the machine this may be made to act just as the wire w has been cut off, or a short time before that. \Vhile the table is depressed the upper portion of the bridge h shuts off the column of buttons in the chute. The presser may be provided with a conical or cup-shaped part, f, to centralize the button, and any inequalities in the size, of the buttons is compensated for by a suitable spring between the presser and this cap.

The wire for the fasteners is wound on a spool, L. and from this is carried between rollers I I, suitably mounted at the side of the machine. Motion is imparted to these rollers by a ratchet-wheel, J, which is actuated by a pivoted pawl-lever. g, havinga pawhg, hinged thereto. The pawl is carried upward bya lateral lug of the rod F, and descends ofits own weight. After passing from the rollers the wire is carried to the cuttingdies E 'E" by a guide, w, the hole through the guide at the terminus next the dies being but a trifle larger than the wire, so that the same is directed with certainty to the hole in the button shank.

In the application of the machine to the attaching of shoe-buttons it is desirable to use two or more sizes of wire for the fastenersone for ordinary work and a smaller size for ladies fine shoes. The machine may therefore be provided with double feed-rollers for the wire and with mechanism for shifting the one or the other in and out of gear at will. The devieefor this purpose is shown in Figs. 12 and 13. Rollers I I are mounted loosely on a shaft, on, and as closely together as may be practicable. A sleeve, x,'is secured to the shaft each side of the pair of rollers and forms aclutch-connection with the portion of the hub of each roller next the shaft. The clutch is made to engage with the respective rollers by means of a simple shifter, y, an arm of which connects with the shaft x by means of a loose bearing between two collars. The shifter has a slotted connection with the top of the bed A and is shifted by means of the handle y. A lug, 3 extends downward through a slot in the top of the bed and connects with the wire-guide 10, whereby the-wire is shifted simultaneously with the changing of connection with the rollers. A spline, z, connects the shaft with the hub of the ratchetwheel J, and at the same time admits of the limited movement of the shaft endwise.

In the formation of the fastener it is important that the staple should beheld quite securely in a vertical position. The upper end of the staple is held in the notch t, as already described; but it is desirable that the middle of the staple should also be held to prevent it spreading or becoming otherwise displaced. The device for this purpose is shown in Figs. 6 and 7. It consists of a pair of keepers, u a, pivoted to a convenient portion of the bed-block A, and provided with a spring, a, which tends to throw the stapleholding end a downward, as shown in Fig.6. This portion of the keeper has a notch in which the leg of the staple rests and whereby it is held in position during the upward movement of the dies which form the fastener. As the dies move upwardly, they press the staple holding parts of the keepers uu into recesses formed on the under side of the horn A, and thus serve as the surface against which the eye of the fastener is pressed in finishing. These keepers should be up and out of the way as the staple is pushed forward, and they are accordingly provided with a device which looks them in the upper position until the staple has nearly or quite reached its final position. The pivotal portion of the keeper is provided with a lug extending in the opposite direction to the arm it, and over this lug is mounted a slide, 1), having a head on its outer end, as shown in Fig. 7. The other end ofthe slide passes through the side of the bed-block and terminates in a suitable head, between which and the bed-block is interposed a coilspring, '1), tending to throw the slide inwardly. The action of the parts will be readily under stood. As the keepers rise with the upward movement of the dies 0p, the lugs are correspondingly depressed until they finally reach a point where the head of the slide can slip over them, carried back by the spring. They remain in this position until the forward movement of the plunger Q or the upper end of the bell-crank S brings a portion thereofin contact with the inner head of the slide and forces it outwardly until at the proper time the keeper is liberated and forced down by its spring over the leg of the staple.

The wire-cutters are two simple dies, E E, beveled to the desired angle for cutting off the wire, so that it may have asharp point. The upper die, E, is set in a suitable socket in the top of the bed-block, so that the lower side of said die is about flush with the under side thereof and on the level of the wire as fed to the button-shank. The die E is a plug of similar shape in cross-section secured in the upper end of the rod E, and is adapted to move vertically in suitable guides.

In the use of two button-feeders the chutes are necessarily set at an angle, converging at the bottom to near the common center, space being preferably left between them for theindependent chute N. Each side of the central space the ends of the chutes are closed by suitable fixed stops, h 7t. Either chute is thrown in or out of gear by simply moving the standard 0 backward or forward, it having a slotted connection with the bed-piece A for that purpose. The same movement throws it in or out of connection with the feeding apparatus of the drums, as indicated by the dotted lines in Fig. 13. In the middleposition there is no connection of the operative mechanism with the button-drums, the independent chute supplying their functions. The rack F,which imparts motion to the drums B B, is in this case attached to a supplemental arm of the rod E, and as thisarm crosses the path of the wire 10 the same may be bifurcated, as shown, to admit of the passage of the wire.

The operation of the invention will now be clearly understood. Supposing that the machine is in its normal position with the pedal of the footlever up, the relative position of the parts will be the reverse of that shown in Fig. d-that is to say, the plunger will be forward and the dies will be down. The first downward motion of the foot-lever moves the dies upward and the plunger backward. As the dies continue to move upward, they form and finish the fastener. In the meantime, or during the last third of the stroke, the wire 10 has begun to feed toward the eye of the button, and about the same time the presser has begun to push the button and the button-table down to position for the shank of the button to receive the wire. This movement is completed just as the plunger passes the hole in the bedblock through which the table descends. The final motion of the pedal downward cuts off the wire, and on theliberation of the foot from the pedal the spring carries the plunger f0rward, forming the staple and completing the movements of the machine. The operation of the drum B and its connections being independent of the mechanism which forms the fastener, it may be moved at any time during the stroke of the machine. After the wire has passed through the shank of the button and the free end has passed the openingin the bed through which the button-table descends, the button need be no longer held by the presser, which may rise at once to its normal position. The spring k then tends to lift the button-table, thus drawing the wire up against the under side of the bed A and holding it secure from displacement while being cut off. When the button has been carried out of the table by the forward movement of the plunger, the table at once springs up to its normal position and receives another button from the chute.

\Vhile the machine as already described is more specially adapted to the formation of fasteners with two tangs, it may also be used to make a single-tang fastener, the only material change being in the construction of the device for forming the connection of the fast ener with the button-shank and the position oft-he cutters. This modification is illustrated in Fig. 21, where the short end of the wire is carried a quarter of a revolution farther than in the case of a staple by the increased turning of the wing at", governed by the spiral guide 9". One-halfofthc mechanism for formingthe fastening from the staple will of course suffice for a single tang.
