SEAT-LOCK.

SPECIFICATION forming part of Letters Patent No. 324,643, dated August 18, 1885.

Application filed November 15, i884.

.To LZZ whom it may concern:

Beit known that I, EBENEZER H. BOOTH, a citizen of the United States, residing at Kirkwood, in the county of Broome and State of New York, have invented certain new and useful Ilnprovements in Locks for VehiclelSeais, and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form apart of this specieation.

Figure l of the drawings isa representation of this invention, and shows a front view of the lock. Fig. 2 is a vertical section taken through the lock, seat-riser, and rail. Figs. 3, 4, and 5 are perspective views of the different parts of the lock.

This invention has relation to wagon-seat locks; and it consists in the construction and novel arrangement of devices, as hereinafter set forth, and pointed out in the appended claims.

In the accompanying drawings, the letter A designates the rail of the wagon, and B the seat-riser, to which the lock C is attached.

The lock consists of the plate D, hook E, and cam-lever F. The plate D is formed with a socket, G, having an interior shoulder at about its middle portion, as shown at h, above which its diameter is larger than below said shoulder. This socket is open at its lower and back part, as indicated at k, this open portion being closed when the plate is attached to the riser. On each side of the socket are the perforated lugs Z, through which the fastening-screws pass.

An upward extension, V, of the plate is formed with a perforated wrist-head, m,where of the wrist-bearing a serves to receive the eye s of the cam-lever F, a screw, a, connecting the paris and passing through the wristhead. This construction is designed to take the strain of the leverage off the screw-connection.

The hook has a rounded shank, b, which is formed with a shoulder, c, above which it is enlarged, as indicated at cl, the enlargement having a slot, e, extending through it from side to side. This enlargement ts in the up- (No model.)

per portion of the socket, and its shoulder c, when it is in position, engages the interior shoulder of the socket, hereinafter referred to. L

The hook branch e extends from the lower end of the shank, and is provided with a spur, t', at its end, which is designed to engage the under side of the rail. The hook can be turned outward for disengagement or inward when the lock is to be used.

The cam-lever F is provided with a curved wedge-arm, H, which is designed to pass through the slot c of the enlarged head ofthe shoulder, and at the same time to bear against the Lipper end of the socket. Vhen the leverarm is pressed down, the wedge arm or cam is pressed through the slot, causing the hook to rise and its hook branch to become forcibly engaged with the rail of the wagon. The engagement of the wedgearm of the lever with the slot of the hook also serves to hold said hook in position, )reventing it from turning outward from under the rail. The wedgearm is designed to afford a continuous takeup, so that the connection is not rendered unserviceable by wear. The leverarni is longi tudinal usually, and its weight is designed to prevent the look from jarring loose. The fastening becomes tight when the point of the lock takes on the rail, and the wedgcarm accommodates itself to the hook, as it will become secure at any point when the strain of the hook is brought to bear.

The socket is open at the back sufficiently to allow the enlarged head of the hook to be introduced, this opening extending a little above the shoulder of the socket. When in position, the enlarged head of the hook engaging the socket-shoulder prevents said hook from dropping out when the cam-lever is disengaged.

In the construction shown the groove or socket can be made to project below the top .of the rail, and in this manner to prevent the body of the wagon from spreading atthe sides.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

1. A seat-lock hook having a slotted cnlargement or head at its upper en d, and a shoulder on the shank below said enlargement, substantially as specified.

2. The combination,with theshoulder-hook,

3. The combination, with the slotted and EBENEZER H. BOOTH. shouldered hook, of the socket-plate having an internal shoulder, and the lever having a Wit-messes: curved wedge-arm designed to engage the S. B. BALL,

slotted hook and the socket,substa11tially as H. P. GANOUNG. specified.
