CHARLES L. PERRY, OF EBENEZER, NEW YORK.

.CONCEALED CAR-DOOR LOCK.

To (all whom it may concern:

Be it known that 1, CHARLES L. PERRY, a citizen of the United States of America, residing at Ebenezer, county of Erie, and State of New York, have invented certain new and useful Improvements in Concealed Car-Door Locks, of which'the following is a full, clear, and exact (.lescription.

The general object of my invention has been to provide a simple and effective means, whereby a car or other door will. be come automatically locked when closed. Moreover, when my door is closed, it cannot be opened except by secret and concealed means, thus -preventing unauthorized persons from getting into a car provided with my lock.

Reference is to be had to the accompanying drawings, forming part of this specification, in which like characters of reference indicate like parts throughout the several views of which Figure 1 is a side elevation of a equipped wit-hmy invention and portion thereof in section. Fig. 2 is a secti nal view taken on line A ii of Fig. 1. Fig. 3 is a sectional view taken on line CD of Fig. 1. Fig. +t is a fragmental sectional view and shows a modified form of a portion of my invention as adapted for swinging doors.

in the drawings represents a sliding car door and 11 the track from which it is slidably suspended.

12 is a fragmental DOIt-lUH of a box car or other inclosure and 133 is the door-jalnb, which is suitably secured in place by any of the well known i'ncans.

From the rear side of the door antl near car door shows a t the front. edge thereof, is cut a recess 14:.

This recess extends from a point near the top edge of the door down to the lowei' edge of the same. Communicating with the rc-- ccss 14 is a recess 15. The recess lSjis cut from the rear face of the door and open at the lower edge of the door and at the lower portion of the front edge of the same.

Disposed within the recess 14 a lock bar it}. This lock haris arranged to be in sliding contact with the front. side of the said recess and is provided prefe 'ahiv near its central portion with suitable gait eways 17. These guideways are preferably mad as shown, they being provided with long arms 18 which extend back toward the rear Specification of Letters Patent.

edge of the door, thereby providing means for securely and strongly fastening the some to the door. Carried between the upper end of the said lock bar and the upper surface of the recess M is aspring 19 of any suitfront end of this lever is provided With an.

upwardly turned projection 23. This projection is preferably in sliding contact with the face 26 of the recess and is held in proper' place preferably by means of the bolt This bolt isslidably disposed in a slot 24 formed in the said projection, thus permitting the said operating lever to be raised but preventing it from dropping down below the face of the lower edge of the door. it plate 27 is set in flush with the front edge of the door and is secured thereto, thus concealing the projection of the said operating lever.

(arried by the door-jamb 13 is a lock bolt 28 which is provided at its outer end with a conical point immediately behind which is provided an annular recess 30. This bolt projects beyond the face of the said door-jainb so that when the door is pushed shut, the said recess will he in register with the lock bar 16. edge of the door is provided with a suitable aperture for the entrance of said lock bolt. The lock bar it; is also provided with an oblong aperture 36 which will register with the largest diameter of the conical point 29 of the lock bolt 28 when the said lock bar is in its uppermost position. The width of the recess 30 in the lock bolt is such as to permit the lock bar to be engaged therewith when it in register with the same. The rear end of the lock bolt 28 is screw-threaded and is held in place preferably by means of a suitable nut 31 which is disposed Within a recess 32 let in from the rear of the door-jainb 18, thus concealii-ig it from View. A pin 33 is passed through the said lock bolt and the door-jau1b when the lock bolt is ing or hinged doors, such'as provided on,

The front refrigerator cars and the like, some means must be provided for withdrawlng the lock .boltwhen opening or closing the door. I

havepreferably carried out this part of my invention by the means shown in Fig. 4-, where 34 represents one of the swinging doors, which carries a concealed casing 35. In this casing is slidably disposed a lock bolt 43, which is provided with a conical point 37 and an annular recess 38. To the rear end of this look bolt is secured one end of a spring 39, the other end of said spring being suitably secured to therear end of the said casing. This keeps the said look bolt back within the casing 35 and flush with the face of the door 34:, when the door is not locked. In the casing 35 and the front face of the door is provided a slot 40. A

. pin 11 is carried by the lock bolt 36 and is slidably disposed within said slot, by means of which the said lock bolt may be pushed out and madeto engage with the lock bar of the look. A plate tiZ-is secured to the pin 41 and is in sliding contact with the view.

face of the door. This plate is wide enough to cover the slot 40 at all times, no matter what position the lock bolt may occupy, thuseiiectively concealing the said slot from It. is of course understood that the other door (not shown) is provided with the lock bar, operating l ver, etc., as is shown in Fig. 1. For convenience in. the drawing, 1 have omitted to show this part of the device in Fig. 4:.

When my device is to be fitted to a single hinged door then the part otthe device shown in Fig. 1- is placed in the door casing.

.door to be opened. When the door is pushed shut the conical end of the lock bolt enters the aperture in the front edge of the door and strikes the lock bar 16. The point of said lock bolt being conical it engages the upper side of the aperture 36 in the lock bar and raises the same until the entire point 29 has passed therethrough, where upon. the said bar, being under spring tension, will engage'with the recess 30 in said bolt, thus securely locking the door;

W hen operating my invention on a hinged door, the operation is just the same as above described, only instead of moving the door away from the lock bolt, this part of the device t) is drawn back into the casing 35. When looking the door, it is first closed and then the lock bolt 36 by means of the pin 41, is moved out and into engagement with the co-acting parts of the lock.

Obviously some detailed modifications may be made from the device herein shown and described-without departing from the spirit of my invention and I do not wish to be limited to the exact construction herein shown and described.

Having thus described my invention, what 1 claim is: v

1. The combination with a door provided with a recess near its front edge and a door jamb; of a concealed locking devige com prising a lock bar slidably disposed in said recess and provided with an aperture, a lock bolt carried said doo'r-jamb and provided with a conical point and. an annular recess behind said point, sald recess being engageable with said lock bar and concealed means for operating said lock bar.
