IMPROVED CAR-COUPLING.

Specification forming part of Letters Patent No. 49,292, dated August S, 1865.

To allwhom t may concern.:

Be it known that LW. O. MORSE, of Boston, in the countyof Suffolk and State ot` Massashusetts, haveinveuted a new and useful Self- Shackling Oar-Coupling; and I do hereby declare that the following is a full, clear, and exact description ot' the construction and operation of the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a side elevation representing the shackling-pin D drawn up, and Fig. 2 is a similar view representing the shackling-pin dropped down. Fig. 3 is a top view, Fig. 4 is a front elevation, and Fig. 5 is an inside plan, of one ofthe clamps J J.

Like parts are indicated by the saine letters in all the drawings.

To enable others skilled in the art to make and use my improvements, I will now describe the construction and operation ofthe same.

A is the bunter or front of the coupling, and B B are the top and bottom pieces, all of iron, and constructed substantially like many in general use.

G is a block of cast-iron, conned between the top and bottom pieces, B B, by means of the bolts a c and screw-nuts b b. In the center of the front end of this block C is a recess large enough to receive the end of the link L, asshown by dotted lines in Fig. 2, and thereby prevent the same from dropping down from a horizontal position.

JJ are metallic clamps, shaped as clearly `shown in Figs. l, 4, and 5, placed behind the bunter A between the top and bottom pieces, by means of screws or rivets to the front ends of the dat springs I I, the back ends ot' which are confined in a similar manner to the sides of the block C. Attached to each of these clamps by means ot' a pivot, a, `(see Fig. 5,) is a cheek, J', which turns freely a few degrees on said pivot in a square-con nered recess in the clamp, as clearly shown in Figs. 4 and 5. Across these cheeks are grounded depressions m m, into which the link L is forced, the springs I I allowing the said clamps to yield enough to receive ir, while at the same time they hold it in any required position, either horizontal or slightly inclined up or down, as may be required to direct it (the link) into another coupling of a similar construction on another car.

It' the two hunters are of the same height, the link L should be horizontal, but it' (as is sometimes the case) one bunter is higher than another, then the link pressed between the cheeks J f J (which turn on their pivots n) may have its outer end elevated or depressed to correspond with the height of the bunter into which it is to be forced and shackled. Y

D is the shackling-pin, bent into the are of a circle, as shown in Figs. 1 and 2, and confined to the front end ot the lever E by means of the screw-nnte, or in any other obvious manner. The back end of this lever isdivided, forming two arms, which are bent as shown in Figs. 1 and 3, and attached to the sides of the block O by means of pivots f f.

G is a sliding arm, the front end of which is round and passes through a holein the bunter A, while the rear end is datand passes through a clasp, H, on the side ofthe block C, as rep resentedin Figs. 1,2, and 3. On the inner side of the arm G is a slot, '10, (see Fig. 3,) which receives the lower end, t, of the forked lever E. Projecting into the slot w is a pin, 7G, which, striking against the lower end, t, ot' thelever E, will raise the latter into the position represented in Fig. 1.

F is a link or dog, the center of which is attached to the side ot' the block O by the pivot i, while its lower end is attached to the arm G by the pivot j. The design of this link is to hold the shackling-pin D and leverE in the po sition shown in Fig. 1, which it does by having its top forced under the shoulder l is a pin or start projecting from the side of the block C, its purpose being to prevent the lever E from rising high enough to draw the shackling-pin D out ot' the hole in the top piece, B.

h is a chain or rope attached to the loop` g, and exteudin g upward to the platform or top of the car, so that a person there may by means of said chain or rope withdraw the shacklingpin D from the link L and into the position.

represented in Fig. l, where it will be held, as before described, by means of the link F. The levers E and Gr and pin D being in the posi sition, shown in Fig. 1, the coupling is ready to receive a link, L, held, as shown in Fig. 2, in the coupling of another car. The link L (being held by the clamps J J of one coupling) will enter between the clamps of the other, and when the bunter strikes the projecting end of the arm-G, forcing il: back into the, position shown vinI Fig. 2, releasing the link F from the shoulder m, and driving the pin, D, downward through the link or dog L, thus forming a selfshackling car-coupling.

My improvement is-very simple, cheap, and efcient, and can be readily applied to man y of the couplings now in general use.

Having thus described the construction and v operation of my invention, what I claim as new,

and desire to secure by Letters Patent, is-

l. The grooved and pivoted cheeks J J f, in

Ycombination with the yielding clamps J J, substantially as set forth and for the purpose described.

2. The arm G, projecting in front of the bunter A, in combination with the lever E and shackling-pin-D, substantially as end for the purpose described.

3. The link or dog F, in combination with the arm G and lever E, for the purpose ofholding up the latter, substantiallyr as described.
