SLIDING-DOOR LOCK.
SPECIFICATION forming part of Letters Patent No. 448,651, dated March 24, 1891. Application filed May 23, 1890. Serial No. 352,315- (No model.)
To aZZ whom it may concern.-
Be it known thatI, OLIVERP. HIX, of Rockland, in the county of Knox and State of Maine, have invented certain new and useful- In provements in Looks or Latches for the Rear Edges of Freight-Car Doors, of which the following is a specification. I
This invention has for its object to provide simple and effective means for securing the rear edge of a freight-car door to the side of the car at the rear end of the doorway; and it consists in the improved devices which I will now proceed to describe and claim.
Of the accompanying drawings, forming a part of this specification,Figure 1 represents a side view of a portion of the rear end of a sliding door and a portion of the side of the car at the rear end-of the doorway thereof, said parts being provided with my improved locking devices. Fig. 2 represents a section on line 2 2 of Fig. 1. Fig. 3 represents a section on line 3 3 of Fig. 2,looking downwardly. Fig. 4 represents an end view of the rear end of the door with my improved locking device thereon, showing a lever and cam arranged to impart inward pressure to the rear end of the door through the locking device, and Fig. 5 represents a side view of the same.
The same letters of reference indicate the i same parts in all the figures.
111 the drawings, a represents a portion of the sliding door'of a freight-car, the portion here shown being at the rear end of the door, and 1) represents a portion of the side of the car at the rear end of the door-opening, the door being shown in its closed position.
0 represents a latch or locking-lever, which is formed on or attached to a stud or shaft d. Said stud or shaft is journaled in a suitable bearing or bearings 6, formed ona plate f, attached to the outer side of the door a, close to its rear end, the said stud or shaft occupying a substantially horizontal position. The locking-lever 0, when in its operative position, extends at right angles with the shaft or stud d, across the rear edge of the door, and is provided at its inner end with a stud or projection 0'.
9 represents a plate inserted in a mortise or socket formed for it in the side of the car, its front being flush with the side of the car. Said plate is provided with a vertical elongated slot h, the upper end of which is .of sufficient width to receive the stud c on the inner end of thelever 0. Below the upper end of the slot h the plateis provided with an inwardly-projecting flange g,which decreases the Width of the slot and has a curved inner face, as shown in Fig. 2, which is preferably somewhat eccentric to the axis of the stud or shaft d and is formed so that it serves as a bearing for the stud 0' when thelatter has been swung inwardly through the slot h, said stud coming in contact with the curved inner face of the-flange g, and being caused by the slightly-eccentric form of said face to press more firmly against it as it descends toward the bottom of the'slot h.
\Vhen the door is closed and it is desired to secure its rear end by the devices above described, the lever c is swung in the direction indicated by the arrow in Fig. 2, its stud a being thus caused to enter the wider and upper end of the slot h and pass down. in said slot behind the flange 9, said stud engaging the flange, as clearly shown in Fig. 3,and thus engagingthe rear edge of the door firmly with the side of the car. To disengage the rear edge of the door, the levercis swung upwardly and outwardly from the position shown in Figs. 1, 2, and 3, the said lever, when in its inoperative position, hanging downwardly from the stud cl in the position indicated by dotted lines in Fig. 2, and being swung upwardly and inwardly from said position when it is next engaged with the flange g. The lever is preferably provided with a knob or handle for the convenience of the operator in moving it from one position to another.
It will be seen that the described device is extremely simple, being constructed in three essential parts or pieces-via, the plate 9, attached to the body of the car, the plate fiwith the bearing 6, attached to the door, and the lever c, with the stud d, said lever and stud being preferably of one piece.
In case it is desired to press the door inwardly with greater force than can be exerted by the simple engagement of the lever c with the flange g, as above described, a cam 7i; and
lever Z may be employed, as shown in Figs. l and 5, said cam and lever being formed on or rigidly attached to the stud or shaft d, which in this case is made in a separate piece from the lever c. The lever c has a socket or oriflee which receives the cam k, the latter being adapted to turn in the said socket.
\Vhen the device is constructed as last described, it is operated as follows: The lever Z is first turned upwardly from the position shown in Fig. 4:, thus throwing the cam 70 inwardly, or toward the side of the car, and permitting the the lever c to be swung into the slot h and engaged with the flange g in the manner already described. The lever l is then forced downwardly by the hand of the operator to the position shown in Fig. 4, thus throwing the cam 7c outwardlyand causing it to strongly press the stud c of the lever 0 against the inner face of the flange g. The door is thus pressed inwardly with greater force than could be exerted by simple pressure of the operators hand upon the lever c, as will be readily seen.
I claim- 1. In a car-door fastener, the combination of a socket f, adapted for attachment to the door, the stud d,journaledin said socket and provided at one end with an arm 0, formed to extend across the rear edge of the door, said arm having a laterally-projecting stud oroffset 0 OlLitS swinging end, and being longer than the thickness of the door, so that the stud on the swinging end of the arm is behind the door when the arm is in its operative position, and a plate g, adapted to be attached to the side of the car and having a flange g, provided with a curved inner face which is eccentric to the path in which the stud c swings, and with a vertical slot or recess at one side of said flange for the reception of the lever c, said slot having an enlargement or recess above the flange for the reception of the stud c',thelever being arranged so that when swung downwardly from a raised position the stud a will enter the slot and bear on the eccentric inner face of the flange and thereby press the door inwardly, as set forth.
2. The combination of the pivoted lever 0, having a stud or offset at its swinging end, adapted to engage a flange orshoulder on the body of a car, the cam 7;, located within a socket at the pivoted end of said lever, and the lever I, attached to said cam,whereby endwise pressure may be exerted on the lever c, as set forth.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 17th day of May, A. D. 1890.
