IOC
The die-block B in its face 23 is provided with a U-formed staple-forming depression or die-opening b, which merges into the depression 22, and the said U-opening, permits die-block B to slide on the end face of the other block A without any interference, as would otherwise be occasioned bythe V-stud, and the depression b is of such area as to provide a semiannular or horseshoe-formed opening between its walls and the walls of the V-stnd, the legs of which opening lead to the head-forming depression in said die-block.
Before the die-block B is forwardly projected the shank-forming wire c is led or fed down vertically through the wire-guide 25 back of and next to the wider portion of the V-stud and against the wire stop or gage 26. The lower end of the wire-guide 25, which is stationary, forms one member of a shear, the other member 27 of which is formed on or attached to the top of die-block B, and as the latter block moves forward into juxtaposition with the block A it .cuts off a section of the wire of a length sufiicient to form the eyeshank, and bends the same into the form of a staple, as indicated in Fig. 13. A suitable slide is next moved to present a lug or stud d thereof, which has a V-formed extremity between the legs of the staple, and a pair of jaws f f next close upon the staple-legs back from the ends thereof and about opposite the apex extremity of the stud (l, thereby spreading the extremities of the staple-legs, the diverging opening between then corresponding substantially to the taper of the said stud d. The stud comprises a screw engaging the slide and is adjustable for longer or shorter shank-legs. The slides or carriers on which thelast-mentioned parts d andffare mounted now move to carry such parts free and clear from the working parts of the dies, and in the meantime the blank y, from which the button-head is to be formed, has been deposited inthe pocket 30 in the jaws 3d 32 of what will be herein termed a blank-receiver. The third die C is at the rear of and between the jaws 32 32 of the receiver, Said receiverjaws move forward with the blank and force the same over and about., being penetrated by the legs of the eye-shan k. The die (l, which had moved somewhat forwardly with the blank-receiver, is now given a still farther forward movement, causing the jaws of the receiver to separate the one from the other, and the said die, coaeting with the dies A B, completes the molding and compression of the button-head, and about at this time the said jaws of the receiver return to their normal positions rearwardly with relation to a position 'near the dies A B, and then after the die O has moved rearwardly the receiver-jaws come together in readiness to receive another blank, which, by suitable mechanism, is conveyed thereto. these operations are repeated.
Proceeding, the parts will now be described more in detail, and D indicates a compara- The button being discharged,
tively heavy bed-piece affixed on the frame of the machine near one end of the latter, and the die-block A is bolted or otherwise confined at the inner edge of said bed D. The said bed-piece D has its lower edge portion 35extended somewhat to underlie the end face 24 of the die A, and such extended portion 35 is provided with a vertical aperture, (indicated by 36,) through which the gage-bar 26 is passed and held in confinement adjustably by the set-screw 37. An upper portion of the bed-piece is formed with or has attached thereto a suitable block or lug 38, through which the tubular wire guide 25 passes and is confined, capable of being adj usted, however, by the set-screw 41. On raising the shear constituting wire-guide 25 and lowering the gage 26, a longer section of Wire may be measured and then cut, or by reversely moving the parts 25 and 26 a shorter section may be gaged and severed. Vhen wire-guide 25 is adjusted higher, the shear part 27 may be correspondingly raised by placing thin strip material between it and the die B.
The bed-piece D has the slideway 40 therein, in which the slide-piece g is movably fitted, and it is upon the seat or rest 42 of the said slide g (see Fig. 7) that the die-block B is supported and confined. In the said figure the die-block B is shown as removed from the seat 42, and the part 27, constituting one member of the wire-shear, removed from the dieblock. The forward or inward motion is imparted to the die-block-carryin g slide g. by the cam 43 on the shaft 44, which is 'rotated through the intermediate shaft 45, geared thereto, and to the main shaft 46 of the machine. The return motion is imparted to the slide hy the cams 47 47 on said shaft 44 working against portions 49 of the extensionframe 50, which is rigidly secured to the slide g. n
The adjustment of the die-block B on the slide g so that it may always be brought in its inward movement to exactly correspond by its end 19 with the face 1S of the die-block A notwithstanding the wear of the parts is insured by loosening the confining-bolts for the clamping-plate 52 and turning the screw 53, which has a screw engagementwith a suitable part of the slide g and bears against a rear portion of the said movable die-block.
In an application tiled by me of even date herewith, under Serial No. 403,368, I have described and claimed automatic mechanism for feeding down or forward the wire in successive hitches or sections, which mechanism may be advantageously used in this machine, and while needing no particular description herein is indicated in the perspective view,
Fig. l, at t', and, as already plain, the feed-in of the wire back of and next to the V-stud takes place, as indicated in Fig. 12, at the time the die B is drawn back, so that on the forward movement of the die it will cut the wire and form it into the staple shape with the IOC IIO
The slides j and k, which carry the tapered shank-leg forming lug d, together with the forming-j aws f f, and the part having the U- shaped cam-socket m for effecting the con traction of said jaws ff, work from dierentl sides and transversely of the machine and at right angles to the line of movement of thel die B. (See, particularly, Figs. 2 and 4.) The slide j has a lateral support and cam-roll 56 thereon, which latter has an engagement in the cam or eccentric slot or way 57 of the camdisk 58 on the shaft 45. The slide k has a similar lateral support andcam-roll, and has an engagement in the cam or eccentric way 59 in the cam-disk 60 on the shaft 62 at the side ofthe machine opposite that at which the shaft 45 is located. Said shaft 62 receives its rotary motion from the main shaft 46 through the gearing 63. The slidej is timed to move inwardly slightly before the slide lc is moved inwardly from the opposite side of the machine, so that the tapered lug CZ may properly be brought between the extremitiesof the eye-shank legs and the hinged or pivotally-hung jaws ff in a line next to and outside of said extremities before the horseshoe-socket or cam m at the extremity of the slide 7a will, as the slide 7c completes its inward movement, force the jaws ff together to effect the spreading of the shank extremities, as most particularly illustrated in Fig. 14. As soon as the slide k withdraws the jaws ff separate by the reaction of the i spring 64, the application of which to the jaws is clearly shown in Fig. 9, and the said slide j and the jaws f carried thereon are also then immediately moved outwardly to clear the way for the blank-receiver y, which at this time holds a blank and is moved to force the latter over and about the extremities of the eye-shank legs.
The blank-receiveris shown in Figs 1, 2, 3, 5, 6, and 14 to 16, more or less in each of said views, and the structure and arrangement of the same will be now particularly described. The said receiver consists of the pair of jaws 32 32, which at the forward ends thereof are inclined so as to meet, as at 70, Figs. 5 and 14, in a common horizontal plane which is coincident with the axis of die C and of the diedepression constituted by the openings 2O and 22 in the die-blocks A and B. Openings are formed, as shown, in the forward extremities of the jaws 32, to constitute, when said jaws are together, as shown in most of the views,
. the pocket 30 for receiving the blank, which as 75, of said'jaws to normally maintain the jaws,4 together with the pocket 30 thereof, intact.
I have in another application for Letters Patent of the United States, filed by me simultaneously herewith, Serial N o. 403,369, described and claimed conveyer devices for receiving therein blanks from the chute (which is indicated at n in Fig. l) and depositing the blanks one at a time :into the pocket of the said receiver, and the said conveyeris slightly indicated at o in Fig. 1; but being made the subject of another application, as mentioned, particular description of the same will not be herein given.
The carrier-frame for the receiver-jaws is movable longitudinally of the machine in suitable ways therefor (indicated at 77) in the carrier-frame F for the die C, which latter carrier is also movable longitudinally of the machine; but its movement is independent of that of the said jaw-carrier E. The inward movement of the jaw-carrier E is secured by the cam 8O on the driving-shaft 46, the same having an engagement with the rear portion 82 of the said frame. The spring 88 (indicated in Fig. 2) effects the return or outward movement of the carrier and the jaws. The rear portion 82 of carrier Eis constituted by a block, as particularly shown in Figs. 3, 5, and 6, which is carried by a couple of parallel bars or rods 84 84, which play in longitudinal sockets therefor in the rearwardly-extended portion of the carrier-frame. The screw 85, by its head against the inner surface of the block 82 and by its shank, screws into the end portion of the frame E. By turning the said screw outwardly obviously the frame may become slightly distended, and then the cam will cause the blank carried in the blank-receiver to be crowded alittle farther upon the extremities of the eyeshank, as in the making of some buttons may be deemed desirable. The blank having been forced upon the shank extremities, and as the blank-receiver is about to move back or moves back, the extreme forward movement of the carrier F is imparted thereto, and the die C is carried into proximity to the ,blank on the shank and the dies A B to mold, compress, and complete the button, and such forward or inward movement of the carrier F insures the forcing apart or separation of the blankreceiving jaws 32. 32. The manner of this operation will be clearly understood on reference to Figs. 3 and 5. The eccentric q, through its strap and connection 90 with the carrier F, positively insures the reciprocatory movement `of the latter, and it will be noted that toward its forward portion the carrier F is provided with the conical head r, axially through and forward of which the shaft or spindle-like die C passes and is supported with a screw engagement. The said head r, at the upper and lower sides thereof, is provided with the friction-rolls 92 92, which bear against the inclined inner portions 93 IIO of the parts comprising the blank-receiver jaws. Clearly the impingement of the head or part r of the die-carrier E against the said separable parts comprising the jaws 32 insures the forcing of the latter apart, the same resuming their closed relations on the return movement of the carrier F.
As particularly shown in Fig. 3, the head r of the die-carrier F has the bore or passage therethrough which is screw-threaded, and the shaft or spindle-like part, in the forward end of which the depression 15 is formed for the die C, is also screw-threaded to engagek By.
the tapped opening through the head r. turning the die-spindle C it may be adjusted for the most advantageous presentation to and coaction with the die-depressions in the blocks A and B. The button having been completed, the dies C and B receding from their working positions, the finished-button is then left, with its axis horizontal, by its eye supported on the V-stud a of the die-block A, and the same may be removed from the machine in any approved manner.
In an application for Letters Patent of the United States filed by me simultaneously herewith under Serial No. 403,366 I have described and claimed an ejecting device which is operative automatically to expel the button from the machine, and such device is shown in Fig. 7 of the drawings at s, and embodies a rod which moves in a groove within the face of the die-block A opposite to the face 18 thereof. The groove in which this ejector plays is indicated at 96 in Fig. 10.
