CAR-LOCK.

SPECIFICATION forming part of Letters Patent No. 422,817, dated March 4, 1890.

Application filed December 2'7, 1889. Serial No. 335,138. (No model.)

To all whom it may concern:

Be it known that I, EUGENE C. MERRILL, a citizen of the United States, residing in West Oakland,Alameda county, State of California, have invented an Improvement in Car-Locks; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to an improved lock for car-doors, which will be more fully explained by reference to the accompanying drawings, in which- Figure 1 is a view showing a door closed and locked. Fig. 2 shows the bolt withdrawn. Fig. 3 shows the door partially open and the bolt removed from the guides.

A represents the side of the car, and B the sliding door.

0 is a hasp strongly hinged or secured to the door and having its opposite end formed with a depressed groove or channel D. When the door is closed, this grooved end of the hasp lies in a depression in the post against which the car-door closes. Upon this post is fixed a strong metal plate E, having the guides F, through which the bolt G slides. This bolt has grooves or channels made in it, as shown at H and I, Fig. 3, and also has the upper part of it made to project slightly over the lower. portion, as at G. The lock J is fixed upon the metal plate by the side of the guides, through which the bolt G moves, and is of such a thickness that one edge passes beneath the overhanging side G of the bolt, so that the bolt acts as a guard to strengthen the lock to prevent its being broken off. The lock is preferably a spring-10ck of any of the well-known or usual forms, and the bolt K falls into either one or the other of the grooves H I in the bolt G. The bolt G, being slid down through its guides when the hasp is in proper position, will pass through the depression of channel D, in the hasp, and thus lock it firmly in place. \Vhen the door is un- 1ocked,the bolt G is slipped up until thelockbolt K falls into the lower of the two grooves H. This groove is inclined at its upper end,

so that if it is desired to lock the door it is only necessary to push the vertical bolt G down, when the incline will force the bolt K of the look back until it passes over the ridge between the grooves and falls into the upper groove I of the vertical bolt, thus holding it firmly in place. The lock-bolt K is withdrawn by a key whenever it is desired to unlock the car, and the vertical bolt G is moved up so as to release the hasp.

The hasp may have an extension or attachment L hinged to it, with a similar channel for locking, so that in some cases the door may be partially opened and locked at that point. This construction also enables me to employ a seal upon the lock- The lower end of the vertical bolt G, having a slot 0 made through it, and a corresponding slot M being made through the proj ecting side of the boltguide, allows a strip of metal, which is to be used for the seal, to pass through the slot and be suitably locked or secured in the usual manner for such seals.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is v 1. A locking device for car-doors, consisting of a hasp connecting the door with the door-frame, and having a transverse groove or channel, a Vertically-sliding bolt orbar eugaging said groove, and a lock with a bolt, which engages and retains the sliding bar, substantially as herein described.

2. The sliding bolt or bar G, with openings I H, and the projection G, above the line of the openings, in combination with the lock, and the lock-bolt which enters said openings, the upper side of said lock extending beneath the projection, substantially as herein de scribed.

In witness whereof I have hereunto set my hand.

EUGENE o. MERRILL.
