LOCK FOR CAR-DOORS.
Application filed July 27, 1914.
To all whom t may concern Be it known that I, GEORGE S'rANnEEsT, a citizen of the United States, and resident of Rochester', in the county of Monroe and State of New York, have invented certain new and useful Improvements in Locks for Car-Doors of which the following is a speciication.
The object of this invention is to produce a locking-device by which a car-door may be fastened in closed position in a simple and convenient manner, and with such security that it cannot be opened without the exertion of considerable force.
To the foregoing end I employ a construction in which cooperating engagingdevices on the door and on the frame or body of the car are moved into and out of cooperative position by manually-operable mechanism, mounted at a point remote from this device, and preferably at the bottom of the car where it is accessible from either side, this manually-operable mechanism being connected with the engaging-device by means passing through a wall of the car, so as not to be accessible from the outside, or liable to injure it by contact with the contents of the car.
Tn the accompanying drawings: Figure 1 is a partial vertical section of a freight-car provided with my improved locking-mech anism, as seen from the interior of the car; Fig. 2 is an enlarged sectional view of the manually-operable controlling-mechanism; and Fig. 3 is a section on the line 3 3 in Fig. 2.
The invention is illustrated as embodied in a lock for the door of a freight-car of ordinary construction, this car having the usual sliding-door 5, moving in guides (not shown) on the outside of the wall 6 of the car, the door being shown in closed position. The door is secured in this position by the coperation of a lug 7 fixed to its inner surface, and a cooperating engaging-device or detent 8, which is pivoted on a lug 9 fixed to the body or framework of the car at the top of the door-way. lln the position shown in full lines in Fig. 1 the detent engages the lug 7, but when the detent is swung to the position shown in dotted lines in Fig. 1 the lug may pass freely beneath it, so as to permit the door to be opened.
The action of the detent is controlled by manually-operable mechanism connected Specification of Letters Patent.

therewith: by an arrangement of links and levers. This mechanism is inclosed in a casing 10 fixed to the bottom of the car, and accessible from either side of the car so that it may be operated by means of a suitable key or wrench. The manually-operable mechanism comprises two shafts 11 and 12, ofwhich the shaft 11 may be extended to convenient points near the sides of the car and is provided with squared or flattened ends 13, as shown in Fig. 3, for the reception of a suitable wrench or key, by which the shaft may be rotated. The shaft 11 carries a mutilated gear 14, which cooperates with a pinion 15 on the shaft 12, so that partial rotation may be imparted to the shaft 12 by the gears. The shaft 12 is provided at the end with a crank-arm 16 which is connected, by a link 17, with a lever 18 pivotally mounted in the wall of the car. This letter is preferably placed, as shown, between the inner and outer sheathing of the car-wall, so as to be completely inclosed thereby except at its lower end, being thus protected from tampering from the outside of the car, and from injury or interference by the contents of the car. The lever has an offset portion 19, so that the opening by which it passes through a diagonal framemember or brace 20 of the car-frame may be as small as possible. The upper end of the lever 1S is connected with the detent 8 by a link 21, which emerges from the side of the car through an opening in the doorjamb 22.
In order to lock the car-door the shaft 11 is given a partial left-hand rotationin the direction of the arrow in Fig. 2, causing the teeth of the gear 14- to partially rotate the pinion 15 and the shaft 12. This partial rotation is continued until the parts assume the position of Fig. 1, in which the crankarm 16 has been moved so as, through the intermediation of the lever 18 and the links 17 and 21, to swing the detent into operative position, as shown. At this point the rotation of the shaft 11 is arrested, so that the gear 14 locks the pinion 15 against reverse rotation. At the same time, reverse rotation of the shaft 11 and the gear 14 is prevented by a pawl 23, coperating with a ratchet wheel 24 fixed on the shaft 11. When it is desired to unlock the door the shaft 11 is given a further slight rotation, in the same direction as before, whereupon the teeth of the gear 14 disengage the pinion 15. The return-movement of the locking-mechanism is produced by a spring 25 connected with the lever 18, as shown in Fig. l. As soon as the gear 15 is released, as just described, this spring swings the lever 18 back to normal position, thus causing the detent to be swung to the inoperative position shown in eratmg withonly one of the doors of the car it will be apparent, without further description, that by a duplication of the detent, and the levers and rods by which it is connected with the manually operable mechanism, both doors of the car may be simultaneously locked and unlocked.
IV claim 1. In combination with a railway-ear having a sliding door and hollow side-walls, locking-mechanism comprising an abutment, on the door, near the edge and the top thereof; a detent movably mounted on the body of the car, in position to move into or out of engagement with said abutment when the door is closed; manually-operable controlling-mechanism mounted externally at the bottom of the car; and connections extending, from the detent, across the doorway, near the top of the car, and thence downwardly, through the hollow Vside-wall, to the bottom of the car and to the controlling-mechanism.
2. In combination with a railway-car havinga sliding door, locking-mechanism comprising an abutment, on the door, near the edge and the top thereof; a detent'movably mounted on the body of the car, in position to move into or out of engagement with said abutment when the door is closed; a rod, for actuating the detent, extending therefrom across the doorway; a lever, for moving the rod, pivoted thereto and pivoted, in upright position, at the side of the car,
the lever extending to the bottom of the car; and controlling-mechanism connected with the lower end of the lever and located in an accessible position at the bottom of the car.
3. In combination with a railway-car having a sliding door, a lock therefor comprising an abutment on the door; a detent pivoted to the door-frame above the door and adapted to swing downwardly into engagement with the abutment when the door is closed; a substantially horizontal rod pivoted to the detent and extending through a wall of the car; a substantially vertical lever located within said wall and pivoted, at its upper end, to said rod, the lower end of the lever extending to the bottom of the car; and manually-operable controlling-mechanism located at the bottom of the car and connected with said lever.
4. In combination with a railway-car having a sliding door, a lock therefor comprising an abutment on the door; a detent movably mounted on the body of the car in position to move into or out of engagement with said abutment when the door is closed; and means, for actuating and controlling the detent, comprising a crank connected with the detent; a crank-shaft for actuating the crank;.a gear upon said shaft; a mutilated gear adapted to coperate with the firstmentioned gear; means for preventing movement of the mutilated gear in one direction; and a spring tending to move the detent out of operative position.
5. In combination with a railway-car having a sliding door, lockiiig-mechanism comprising an abutment, on the door, near the edge and the top thereof; a detent movably mounted on the body of the car, in position to move into and out of engagement with the abutment when the door is closed; manually operable controlling mechanism located externally, at the bottom of the car, and operable from either side thereof; and connections, between the detent and the controlling-mechanism, extending within the side-wall of the car at one side of the doorway.
In testimony whereof, I aiiix my signature in presence of two witnesses.
