AM. PHaTo mHasRAPH/c ca NX osaaR/ve PROCESS) UNITED STATES BENJAMIN HERSHEY, OF ERIE, PENNSYLVANIA.
Specification forming part of Letters Patent No. 139,151, dated May 20, 1873; application led February 14, 1873.
To all whom it may concern:
Be it known that I, BENJAMIN HERsHEY, of the city and county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Chain Machines, ot which the following is a full, clear, and exact description, reference being had to the accompany drawing and the letters of reference marked thereon, making part of this speciica tion, in which- Figure 1 is a front view. Fig. 2 is a vertical sectional view on the line a: x, Fig. 1.
The nature of my invention consists in arranging the head ofthe plunger in such manner, in conection with the hinged bed-plate of a spring, that as the plunger is elevated by the cam, it shall so lift the bed-plate as to cause an arm attached thereto to move a horizontal sliding bar so as to drive its stop in such contact with a pin on the plunger-shaft that it shall hold the latter free from contact with4 the cam, until, through the action of a treadle the sliding stop-bar is returned. The nature of my invention also consists in so attaching the oscillating arm of the spring bed-plate to a crank connected with the treadle-axle as to permit of the tension or forcc with which the spring shall act or drive the plunger, being regulated at pleasure. The nature of my invention also consists in so connecting the treadle-rod with its axle, that as the same is turned, through the action of the oscillating bar connected with the bedplate of the spring, the rod shall elevate one treadle and so depress the other, and the 'one which carries the movable-tongue bearin g pin of the link as to withdraw the same automatically, thus leaving the link free to be removed after it has been welded, through the action of the dies. The nature of my invention also consists in providing the section of the dieblock through which the traveling die works, with a detachable steel packing, which allows of its being removed when unduly worn, or replaced by another of a dierent diameter, and which allows of the same die-block being used with different-size dies, as more particularly pointed out hereinafter.
The construction and operation of my invention is as follows: A is a rectangular frame which supports the entire operating mechanism. On the base-board A of the frame is seated the hollow die-block B, in which is secured by means of a screw or other attachment, the circular grooved or recessed die b. B is a curved steel packing that is fastened in the die-block and extends from the upper section of same down to a point below the face ofthe die b, thus lling the entire section of the block through which the traveling die d operates. This packing B' is to be so secured as to be detachable at pleasure, which permits of dies of di'lferent sizes being used, or the replacement of the packing when through frictional contact it becomes so worn as no longer to insure the true action of the dies b d. G is the plunger and is provided with acollar, D. In this collar D is secured by a bolt-plate, C', the traveling die d, which is a circular, grooved, or recessed die, and the exact counterpart of the die b. When these dies are brought together their concave-and convex recesses form, as it were, an annular i groove, in whichthe scart'ed and open ends ot' the link are welded. The arms c c ofthe boltplate C project out beyond the sides ot' the collar D, and in connection with the slotted faces e e of the bearing guide-plates E E in which they act, serve to insure that the traveling motion of the plunger shall be on. a true and direct linear line, The bearing plates E E, as is also the bearing F of the camshaft, are secured to the cross-plate A2 of the frame and which is mortised or otherwise held at or near the center ofthe same. 0n this bearing F is secured the cam-shaft F', which carries thecam-wheel G. The cam-shaft F and the plunger (l each work in suitable bearings in the top board A3 of the frame. Through an opening or aperture cut through the plunger-shaft is inserted a pin, G', which projects beyond the face ot' the shaft affording an elevating bearing-pin g at the rear, against which the cam acts in elevating the plunger,
as shown in Fig 2, and a. bearing-pin, g', inv
front, against which the stop-bar acts when the plunger is held free from allcontact with the cam, as clearly shown in Fig. l. H is the bedplate, and is provided with a torsionspring, the lateral lever arms It h of which rest on and act against the capp-plate G2 of the plunger-shaft 5 or, if preferred, any other ATENTMQEEQE.
style of spring may be used instead of the torsion-spring shown, the same being so attached to the swinging plate as to act on the plunger in its downward movement to add force and intensity to its blow. This spring bed-plate H is hinged or pivoted at H' to the side of the frame A, as clearly shown in Fig. l. Near the center of the plate H is a slot in which is pivoted, by a bolt, K', the arm K, and
which is so secured as to allow of its free oscillatin g movement. At the lower section of this arm K are a series of openings or apertures 7c 7c, by means of which the arm K is connected with crank I, attached to the treadle-axle L. This crank l has also a series of perforations, either one of which can be made to register with either of the perforations k lc of the oscillating arm K, and which permits of the crank and arm being connected by a bolt Z', as clearly shown in Fig. l. These perforations also permit of the bearing of the arm K being shifted and thus to draw with greater or less strain, as occasion may require, on the bed-plate during the operation of the machine.
Thus it will be seen that the action of the spring is not only controlled, but the degree ofits tension is regulated by the arm K.
The axle L that carries the crank Z to which the arm K is attached, is journaled in suitable uprights a a, secured between the middle and upper boards A2 A3 of the frame, and this axle L carries, in addition to the crank l, the crank M, in the slotted face m of which is se-` cured the treadle-arm M'. N N1 are treadleplates, and are secured in suitable bearings a n at the rear section ofthe frame A, as clearly shown in Fig. l. The forward section of these treadle-plates N Nl is attached to a pivoted bar, N2, in such manner that as one is elevated the other is depressed. This pivoted bar N2 is secured in a vertical arm, a', attached to the under face of the base-board A1. To the trea dle N is secured the vertical sliding tongue O, which, after the link to be welded has been placed on the die b, is forced up so as to atford an interior bearing for the same, and serves to retain it in proper position for the action of the traveling die d; To the 'treadle Nl is attached the arm M'. P is a sliding stop-bar, and works horizontally in suitable bearings in the opposite sides of the frame A. This bar is provided with a shoulder or stump, P', which has an inclined head. When this shoulder, through the action of the bar, passes under the pin g' -on the plunger, it elevates the same so as to hold the plunger free from all contact with the cam G until the bar, through the action of the arm K,is returned. This arm K passes through a slot, p, inthe sliding bar P, and thus automatically moves the same backward and forward.
From the foregoing description the operation of the machine will be readily understood. Power from an engine or any other suitable sourceis applied to the shaft F', which, through the cam G acting against the pin g, elevates the plunger; but as the plunger is being eleva-ted, its cap-plate C2 so lifts the bed-plate H as -to cause its oscillating yarm K to so move the sliding stop-bar P as to drive its shoulder P' under the pin g' of the plunger, and to so elevate the latter as to hold its pin g free from the face of the' cam G. This movement of the arm K has also, through the crank Z, so turned the axle L as to cause it, through the crank M and rod M', to elevate the treadle N', and which has correspondingly depressed the treadle N, which so withdraws the tongue O as to leave its head below the face of the inferior die b. The machine is now in position as clearly shown in Fig. 1, and is in the desired position for the reception of the link that is to be welded. The link, having its open edges properly scarfed, and having been heated in a blacksmiths or other suitable furnace to a welding heat, is now introduced for the action of the dies. The operator with his foot now depresses the treadle N1, which instantly elevates the treadle N, andwhich movement instantlyy drives the tongue O up through the slot in the link, where it serves to steady and retain the latter for the action of the dies; but this depression of the treadle N1 has, through the rod M', so acted on the axle L and its crank las to swing back from its advanced position the oscillating arm K, and it returns the stop arm P, leaving the bearing-pin g' of the plunger free from contact with the shoulder P' of said arm, and consequently the op posite-bearing-pin g now falls on the face of the cam. The plunger, being now free to act, falls, the accumulated tension of the spring adding force and intensity to the blow. This fall of the plunger, through the action of the dies b d, welds the link. As the plunger is again elevated, it serves to lift the bed-plate, as before. It again, through the arm K, so moves the sliding bar as to arrest and hold the plunger, and also, through the axle L, crank M and rod M', elevates the treadle N1, which so depresses the treadle N as to withdraw the` bolt or tongue O, and which permits of the Welded link being withdrawn and another inserted. Y Y
