Application filed February 16,1899. Serial No, 705,651. (No model.)

To all wiz/011e t may concern:

Be it known that I, CHARLES P. VATERS, a citizen of the United States, residing at Detroit, in the county of lVayne, State of Michi gan, have invented certain new and useful Improvements in Locks for Car-Doors; 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 the same, reference being had to the accompanying drawings, and to the letters of reference marked thereomwhich form apart of this specification.

This invention relates to new and useful improvements in car-door locks especially designed for use on freight-cars; and it consists in the construction and arrangement of parts hereinafter fully set forth, and pointed out particularly in the claim.

The object of the invention is to provide a lock for car-doors which will automatically lock the door when closed, whichis strong and secure, simple of construction, and inexpensive, and which enables thev car to be readily and perfectly sealed when desired.

This object is attained by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective viewof a portion of the side of a car, showing my improved lock applied to the door thereof, other parts being broken away. Fig. 2 is an enlarged plan View in detail, showing the parts of the lock separated. Y Fig'. 3 is an elevation showing the parts in a locked position. Fig. 4 is a vertical sectional view, as on line 4 4 of Fig. 3.

Referring to the letters of reference, A designates a plate adapted to be secured to the jamb-cleat A', located at the front edge of the door-opening. Projecting from the vertical face of said plate is a series of brackets a, through which passes the vertical lockingbolt B, which is adapted to reciprocate vertically. Extending from the side of said bolt is a downwardly-curved arm C, which is provided at its outer end with an inclined face l?.

Embracing the front edge of the door D and firmly secured thereto is a rectangularbracket E, from the outer edge of which projects a curved latch F, which extends beyond the edge of the door and in line with the curved arm C of the latch-bolt. The forward end of the latch F is tapered and is inclined on its upper face, as shown at c, and is provided with a vertical aperture d through its forwardly-projecting end.V The arrangement of the parts is such that upon the closing of the door the point of the latch engages the beveled face b of the curved arm and raises the latchbolt B, said arm riding upward on the inclined face c of the latch until its lower point drops over the shoulder e of said latch, at which time the aperture in the end of the latch is directly under the raised end of the latch-bolt, when said bolt will fall, causing its lower end to pass through the aperture cl in the latch and through the lower bracket a of the plate A at the same time the curved arm C drops behind the shoulder c of said latch, as clearly shown in Figs. l and 4, whereby the door is securely locked, as will be well understood. When it is desired to open the door, the latch-bolt is raised, through the medium of the curved arm C, until its lower end is free from the latch F, as shown by dotted lines in Fig. 3, when the door may be readily opened. With the arrangement shown and described it will be understood that the door becomes automatically locked whenever it is closed.

Upon the side of the latch-bolt (see Fig. 4) is a shoulder f, which engages one of the lateral brackets c of the plate A, so as to maintain the latch-bolt at the proper height to enable the latch. to engage the beveled face of the curved arm thereof and raise said bolt in the operation of closing the door.

To provide for sealing the door when locked, a boss g is formed upon the latch-bolt, in which is formed an aperture o, while a similar aperture o is formed in the lower end of said bolt, so as to enable the passing of the wires??J therethrough and the sealing of said wires, as shown in Fig. 4.

Having thus fully set forth this invention, what is claimed is- Y In a lock for car-doors, the combination of the plate adapted to be secured to the jamb of the door having lateral brackets, the latchbolt supported in said brackets to move vertically, the outwardly and downwardly curved armprojecting from said latch-bolt, said arm at its outer end having an upwardly-beveled ing portion of the arm depending from said face, the bracket attached to the edge of the l1holt. 1o doorhaving the outwardly and forwardly pro- In testimony whereof I sign this specicajecting latch, said latch having an inclined tion in the presence of two Witnesses.
