Application filed November 17, 1913, Serial No. 801,322. Renewed January 31, 1916.

To all whom it may concern:

Be it known that I, YSIDORO Rouo, a citizen of the United States of Mexico, residing at the city of Mexico, Mexico, have invented certain new and useful Improvements in Car-Door-Locking Mechanism, of which the following is a specification.

This invention relates to improvements in car door locking mechanism.

The primary object of this invention isto provide a locking device specially adapted for freight car doors and relates to that class of such devices in which the locking means is associated with the hinge members of the door.

Another object of the invention is to provide a hinge lock adaptable for efficient use with a door that is slidably mounted although being capable of use ing door structure.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists of the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings forming a part of this application and in which like reference characters denote corresponding parts throughout the several views: Figure 1 is a front elevation of the mechanism controlling the opening and closing of the car door and the actuating of the register and indicator, 2. portion of the door being shown and said mechanism illustrated and detached from the car. Fig. 2 is a top plan view of the swinging hinge device at the lower end of the door and showing the position of the elements at the first stage of the door opening operation. Fig. 3 is a vertical detail of a portion of the door showing a channel guide support and pin and bottom plate upon which the door slides.

Referring more in detail to the drawings, it will be noted that the car door 1 may be broadly stated as slidably positioned upon the side of the car 1 with the bottom portion of the door slidable upon a guide plate 8 having a marginal inclosing flange 8 curved as at 9 at the forward end of the door to give proper direction to the door during both the opening and closing operation.

Stationary plates 2 and 2 are secured to the frame of the car adjacent the rear edge 1 of the door when closed, at the top and Specification of Letters Patent.

Serial No. 75,470.

secured longitudinally inclosing both the top and the bottom of the door, said plates provided with longitudinal slots 7 which receive headed pins 4 mounted upon the hinge plates 3, 3* and by which means the door is capable of hinging outwardly as shown in Fig. 3 and sliding longitudinally upon said pins 4 to the open position shown in dotted-lines in Fig.2.

Upper and lower bolts 16and 16 respectively are shdably mounted in strap plates 16*" and 16 respectively to be moved by the actuating mechanism 23 away from and toward each other. The opposite free ends of said bolts 16, 16 are projectable within and through openings 16 and 16 of the said hinge plates 8, 3 when the said openings of the plates are brought into alinentlent with the said bolts. The stationary plates 2, 2 are provided with keeper openings 16, 16", and into which said ends of the bolts 16, 16 are respectively adapted to enter when the said ends and the said openings of the hinge plates are brought into registry therewith and all of which is occasioned only upon the complete closing of the door 1. Levers 25, 24 have their free ends hinged to said bolts 16, 16 by the rivets 25 and 24 respectively, while said lever 24 has its opposite end pivoted at an intermediate angular point 26 to said plate and has an angular end extension 25 engaging within a curved portion of the lever 24. A spring 28 secured to the plate 23 bears upon the lever 24 normally retaining the same and its bolt 16 depressed while a similar spring 29 engages the lever 25 with an upward pressure for normally holding the bolt 16 upwardly.

From the above detailed description of the device the complete operation thereof will be apparent as the manner of locking and unlocking the door in conection with the hinge members upon which the dooris mounted is evident.

What I claim as new and desire to secure by Letters Patent is 1. A device of the class described comprising in combination with a car door, stationary oppositely positioned keeper plates, journaled hinge plates flatly engaging said keeper plates, said journaled plates and keeper plates each provided with perforations therethrough, locking bolts with their ends projectable through the perforations of said journaled plates and adapted for entering the perforations of said keeper plates upon an alinement of the perforations of said journaled and keeper plates.

2. A locking mechanism comprising in combination with a door, stationary oppositely positioned keeper plates having keeper sockets in their inner faces, longitudinally slidable locking bolts mounted between the said plates and in alinement with the said sockets, journaled shiftable hinge plates for the door flatly engaging the inner faces of said keeper plates and positioned between the said keeper plates and the free ends of said bolts when the said bolts are retracted in their unlocked positions, the said hinge plates having perforations therethrough p0- sitionable in alinement with the said bolts and keeper sockets when the door is in its closed position.

3. A locking mechanism comprising in combination wlth a door, oppositely positioned keeper plates having parallel inner sockets when the door is in its closed posi- 7 tion and annular holding shoulders for the said hinge plates provided upon said rod adjacent the said hinge plates.

In testimony whereof I hereunto afiix my signature in presence of two witnesses.
