' UNITED STATES PATENT OFFICE.

STEPHEN TAPPENDEN AND RICHARD S. TAPPENDEN, OF NORTH AMHERST, OHIO.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 256,762, dated April 18, 1882.

Application led February 8, 1882.

To all whom it may concern:

Be itknown that we, STEPHEN TAPPENDEN and RICHARD S. TAPPENDEN, citizens of the United States, residing at North Amherst, in

the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Car-Couplings, of which the following is a specification, reference being had therein to the accompanying drawings.

Ouriuvention relates tocar-couplings; and it consists in the construction and arrangement of its several parts, as will be hereinafter fully set forth, and pointed out in the claims.

In the drawings, Figure 1 is a vertical longitudinal section ofthe draw-head, showing the coupling apparatus therein. Fig. 2 is a iront view, and Fig. 3 is an elevation of the camlever. It is made in sections, upper and lower, as shown.

In the forward portion of the drawhead is a recess, a., which has openings a in its upper side, a? in its lower side, and a3, into which the link passes. Pivoted in the rear portion of the recess is the clutch B. It extends forward, and its front end is curved from top to bottom inwardly, as shown. In the bottom of the clutch is a recess, o, in which the link is caught and held, as shown.

Projecting from the upper side ofthe clutch 3o and passing through the opening a is a pin, b, the upper portion of which is provided with a slot b', as shown.

O is a cam-lever, of which o is the cam portion and c the handle. Projecting at right angles from the center of the cam portion isa pin, c2, which passes through the slot b of the pin b, as shown. The bottom portion of the lever is straight, as shown, and the periphery .of the cam portion is beveled, as shown. This 4o lever is pivoted to the rear side of the pin b, with the top of the bevel, or, in other words, the longest side of the lever, next to it. When the link is within thedraw-head and held by the clutch, as shown in Fig. 1, the iiat portion of the lever C rests against the top of the drawhead, as shown. When it is desired to raise (No model.)

the pin and clutch to release the link, the handle of the lever is grasped and carried over to either side, as shown in dotted lines, Fig.

2, which will raise the pin b, because the dis- 5o tance from the pin o2 to the side of the lever is greater than that from the pin to the top or straight portion upon which the lever rests whenthe clutch is down.

It will be understood that as the pin is raised by the lever it will incline backwardly, and the lever, by reason of the bevel upon the periphery of its cani portion, will always bear its full width upon the top of the draw-head. The draw-head will also act automatically by 6o reason of the curved front of the clutch. The link striking the curved end will be deflected downwardly to the bottom of the opening a3, will then raise the clutch up, pass along the recess beneath it, and be caught in the notch, as shown.

What we claim isl. A draw-head formed in sections, upper and lower, and with a recess, a, and openings a a? a3, substantially as shown and described. 7o

2. In a draw-head, the clutch B, pivoted in the rear portion of the recess a, provided with a pin, b, having a slot, b', and notch in its lower side, substantially as and for the purposes set i'orth.

3. ln a drawhead, the cam-lever C, consist ing of the cam portion c, handle o', and pin c2, adapted to pass through the slot b' of the pin b, substantially as and for the purposes set' forth.

4. In a draw-head, the combination of the clutch B and its slotted pin b with lever C, beveled as set forth, and draw-head A, substantiall y as shown and described.

In testimony whereof we hereby ax our signatures in presence of two witnesses.
