MACHINE FORMAKING CLlP-YOKES.

EPECIFICATION forming part of Letters Patent No. 312,534, dated February 17, 1885.

Application filed July 30, 18:14. (No model l To all whom it may concern.-

Be it known that 1, WILLIAM S. WARD, of Plantsville, in the county of Hartford and State of Connecticut, have invented new 1m- 5 provements in Machines for Making Carriage Clip Yokes; and Ido hereby declare the following, when taken in connection with the acccompanying two sheets of drawings and the letters of reference marked thereon, to be Io a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a top or plan view; Fig. 2, a front View; Fig. 3, a sectional view through the 1 punches h h,- Fig. 4, a sectional view cutting through the die; Fig. 5, a section through the die at right angles to Fig. 4; Fig. 6, a perspective view of the die inverted; Fig. 7, a perspective view of the yokecomplete.

' This invention relates to an improvement in machines for the manufacture of the article commonly called carriage-clip yokes that is to say, the bar-like piece which extends across the under side of the axle, and through which the two ends of the clip pass, and so that the nuts turned onto the ends of the clip will bear against the bar to serve as a clamp to hold the parts clipped to the axle. This article is shown in perspective in Fig. 7. It

consists of a bar, A, of iron, having a hole,

a, at each end. The ends are square, but the corners rounded, so as to present a neat and finished appearance, and as shown in Fig. 7. These yokes are usually forgedbetween dies in a drop-press.

The object of my invention is to construct a machine which, receiving the heated bar, will cut from it the proper lengths, shape, punch, and deliver the yokes complete with- 0 out other manipulation than simply present ing the bar to the machine; and the invention consists in the machine hereinafter described, and more particularly recited in the claims.

B represents the bed of the machine, on 5 which the operative mechanism is arranged; O, the driving-shaft in bearings D D, and to which power is applied through the pulley E, or otherwise.

On the driving-shaft 01s a bevel-wheel, E, which works into a corresponding bevel-wheel, G, on a tranverse shaft, H, arranged in bearings J.

L is the die-block, which is arranged on the the bed of the machine, as seen in Fig. 4c. In this block the die M is arranged. This die M is shown in perspective in Fig. 6, inverted.

It is constructed with a cavity, N, correspond-. ing in shape to the face of the yoke. The rounded shape of the corner is shown in one of the angles in the cavity in said Fig. 6'. The bar 0, from which the yokes are to be forged,

is passed inward on the top of the bed and against a guide, 1?, which conducts it beneath the die M, as shown, and so that its inner end will abut against a stop, b, when it has arrived at the proper relative position to the die. This stop is also seenin Fig. 6, and made as a part of the die. Directly beneath the cavity in the die isa vertical punch, R, to which an upand-down reciprocating movementis imparted 7o by means of a cam, S, on the driving-shaft G through a lever, T, thecam 'serving to force the slide upward and a spring, U, to return it. The end of the bar standing between the cavity in the die and the uppellend of the punch R as the punch rises, as indicated in broken lines, Fig. 4, outs on" the end of the bar and forces the piece so cut into the cavity of the die, as indicated in broken lines, Fig. 4,which gives to its upper corners the rounded shape. This done, the punch It returns until flush with the top of the bed, as seen in Fig. 4. The blank thus shaped follows down upon the punch, and will there stand directly in front of a slide, (1, which reciprocates at right angles to the bar 0, caused so to move by a cam, e, on the shaft H, which acts to force the slide inward, and the spring F, which serves to re- .turn it. The forward or advance movement of this slide at occurs so soon as the blank has 0 dropped from the die. The slide moves forward directly beneath the die, and in such movement transfers the blank from beneath the die to a position beneath the punches'h h. These two punches are in diameter corresponding to the holes a a to be made in the yoke, and are set in a vertical slide, 2', which is arranged in vertical guides, and to which an up-and-down reciprocating movement is imparted by a cam, 70, on the drivingshaft 0, through a lever, Z, one end hung to the upper end of the slide. The cam imparts a downward movement to the punch-slide, and the spring m returns the slide and punches. As the slide D moves forward it forces the blank against an abutment, n, and so as to clamp the blank between the end of the slide (1 and the abutment n, as seen in Fig. 5.

At right angles to the slide d and abutment n is a slide, 1", arranged to move back and forth under the action of the same cam, k, which opcrates the lever Z and a spring, 8, the cam serving to force the slide 'r forward and the spring to return it. This slide stands directly beneath the punch -lever, as seen in Fig. 3, and so that as it is moved forward it closes one end of the space between the slide (1 and the abutment a.

In the same line with the slide 1', and forward of it, is another slide, t, which corresponds to the slide r, and is moved back and forward toward the slide 1" under the action of a cam, 2, through a lever, 3, and a spring, A, the cam serving to force the slide t toward the slide 1' and the spring to return it. The slide it closes the opposite end of the space between the slide d and the abutment a, and,as seen in .Fig. 3, the space thus inclosed by the slide (1, abutment n, and the two slides 1' t, corresponds to the two sides and ends of the blank for the yoke.

After the slide (2, as before described, has transferred the blank and set it against the abutment a, the two slides r and t come up against the ends of the blank, so that the blank is firmly held upon its two sides and ends. Then the slidei descends and forces the punches h it through the blank, the blank be ing supported from below by a die-plate, 5, as seen in Fig. 3, to resist the punching. This done, the punches are withdrawn. Then the slide (1 recedes, as also the slide 1*; but the slide t advances, as indicated in broken lines, Fig. 3, and takes with it the yoke from its position beneath the punches, and carries it to an opening, 6,in the bed, through which it drops. Then the slide 25 recedes under the action of its spring.

The bar 0 is then forced forward beneath the die, a second blank cut, and the work proceeds as before, one yoke being completed at each and every operation of the machine.

To insure the delivery of the blank from the die, a follower, 7, is arranged through an opening, 8,in the top of the die, as seen in Fig. 4. This follower is actuated through the lever T, which carries the punch R, as seenin Fig. 4; or it may be otherwise operated, so that after the blank has been shaped it will follow and force the blank from the die.

While I have represented the reciprocating movement as imparted by acam in one direction and spring in the opposite direction well-known devices for producing such reciprocating movement-it will be understood that other known equivalents may be employed for imparting such reciprocating movement, and whereby, if desirable, that movement in both directions may be positive.

I claim- 1. The combination of the die M, havinga cavity, N, upon its under side, shaped corresponding to the face of the clip-yoke, the reciprocating punch R, the slide (1, abutment n, the slides rt at right angles to the slide (2, substantially as described.

2. The combination of the die M, having a cavity, N, upon its under side, shaped corresponding to the face of the clip-yoke, the re ciprocating punch R, the slide d, abutment n, the slides r t at right angles to the slide d, and the vertically-reciprocating punches h h, substantially as and for the purpose described.

3. The combination of the die M, having a a cavity, N, upon its under side, shaped corresponding to the face of the clip-yoke, the reciprocating punch R, the slide d, abutment n, the slides r tat right angles to the slide (1, with the follower 7, substantially as described.

4. The combination of the die M, having a cavity, N, upon its under side, shaped corresponding to the face of the clip-yoke, the reciprocating punch B, the slide d, abutment n, the slides r t at right angles to the slide d, the follower 7, and the vertical]y-reciprocating punches h h, substantially as described.
