IMPROVEMENT IN CAR-COU PLINGS.

Specification forming part of Letters Patent No. 42,696, dated May 10, 1861.

T0 aZZ whom it may concern:

Be it known that I, STRIGKLAND SLACK, of Oxford, in the county of Chester, in the State of Pennsylvania, have invented a new and Improved Mode of Constructing the Shackling for Railroad-Cars; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The object of my invention is to provide a means by which railroad-cars may be shackled and unshackled without the necessity of a man going between the cars for that purpose, and thus avoiding accidents, which frequently 03cm in that operation.

To accomplish this I construct my bnnter in the form of an elongated square box, A A, Figure I. IVithin the bunterI place the piece of metal B. Fig. IV, is a perspective "iew of the piece B, Fig. I, detached from the bunt- (-r. This piece of metal is attached to the end ofa metallic rod, 1), within the banter, as shown in Figs. I and III. The other end of the rod passes through ahole in the partition C, Figs. I and III, which will admit of the piece B being moved back and forth in the banter. Between the piece B and the partition C the rod is surrounded by a spiral spring, or its equivalent, which extends from the piece B to the partition C, as shown in Figs. I and III. When the bolt D is drawn out and the link E is removed, the spring forces the piece B out so that the projecting part of it passes under the upper hole in the b inter through which the bolt D passes and prevents the bolt from dropping through the hunter until the piece B is forced back by the link E. The link is made in the form shown by Fig. V, which is a flat iron bar with an oblong hole through each end through which the bolt passes. This mode of making the ink greatly increases the strength thereof.

Fig. III represents the hunter with the bottom part removed, and with the link and bolt in the position they occupy when the cars are shackled. Fig. II is an end view of the car, with my arrangement for unshacklin g.

FFFis a frame for the support of thelevers. G is a le er with its fulcrum at H, and the end extending through the bolt D. The bolt is retained on the lever by the knob I, or by any other means that will answer the desired end. K is also a lever with its fulcrum at L near its center, M being the handle. The levers are connected by the rod N, attached to the end of the lever K, by means of a nut, or otherwise,as is shown at O. The other end of the rodis attached to the lever G, as is shown at P. Bearingdown the handle M raises the lever Gr, to which the bolt D is attached, and draws the bolt out of the hunter, when the pieceB springs forward and prevents the bolt fro-m dropping through the bnnter until the piece B is forced back beyond the hole by the link E.

In shackling, the link E, on entering the opening of the hunter, strikes the piece B and forces it back, and the bolt D drops through the link and shackles the cars, avoiding the danger in going between the cars for the purpose of inserting the bolt. In unshackling, the man,instead of going between the cars, stands on the platform of the car, or on the top, and by bearing downthe handle M draws the bolt 1) out of the hunter and unshackles the cars.

hat I claim as new in my invention, and desire to secure by Letters Patent, is-

The piece B and spring b, in combination with the levers G and K, the bolt D, and the link E, substantially as set forth, and for the purpose specified.

STRICKLAND SLACK.
