LOCKING DEVICE FOR CAR-DOORS, 86C.

SPECIFICATION forming part of Letters Patent N o. 495,327, dated April 11, 1893.

Application tiled May 10, 1892.

- To all whom it may concern:

Be it known that I, WILLIAM W. HALEY, of Moline, county of Rock Island, and State of ll/Iy invention relates to locking devices for sliding doors, and more particularly, to those doors used for closing the openings in freight cars.

The object of my invention is toprovide a simple inexpensive and. effective device for this purpose, and it consists primarilyin pro- Viding the door with a locking lever having its end oset and arranged to engage a notched bar secured to the car body or other relatively fixed structure on which the door is mounted and adapted to be secured to lock the door in adjusted position.

My invention also consists of the details of construction and combinations of parts hereinafter described and claimed.

In the accompanying drawings,-Figure l represents a side elevation of a portion of a car provided with a sliding door and a locking device embodying my invention, the locking device being shown in an operative position. Fig. 2 is a similar view with the locking device shown in an inoperative position. Fig. 3 is a vertical cross-section on the line 3-3 of Fig. l.

Referring to the drawings,-A represents a portion of a car provided with the usual side opening which is closed by a sliding-door B. This door is provided at its lower edge with plates b b', on which are mounted rollers b2 b3, adapted to travel on a track C, iixed to the car-body below the opening, as shown. At itsy upper end the door is provided with plates D D', on which are mounted rollers d d', adapted to travel on a track E, fixed to the body above the opening therein.

The foregoing parts are substantially the same as the constructions now employed in connection with car doors, and except in so far as hereinafter indicated they form no part of my invention.

In carrying out my invention I provide the under edge of the upper track E, with a series ot teeth e c', &c., forming in eect a notched bar or rack, and I pivot to the door at f, a locking-lever F, consisting of the straight hanafter.

Serial No. 432,468. (No model.)

dle or body portion f', and the angular offset end f2, the latter adapted to engage the notched bar, as more fully described herein- The offset end of the lever is formed bybending its upper end at an angle to its body portion and a nose g, is formed on the end of the offset portion, which nose is adapted to enter between the teeth on the track E. I prefer to locate the pivot f, near the upper end of the lever, adjacent to its offset portion so that the arc in which the nose travels will curve as much as possible. As a result of this arrangement when the handle of the lever is moved from the position indicated in Fig. 2, to an operative position, to lock the door, as

shown in Fig. 1, the nose of the lever will be caused to move upward in a nearly vertical path and will readily enter snugly between the teeth so that the door will be held securely in position and any rattling or loosening ot' the parts avoided.

It will be observed that 'under the construction described the door may be locked and held in any desired position over the opening, as circumstances may demand, and that the device may beapplied to existing cars provided with sliding doors without materially changing the construction of th-e parts.

The lever may have its handle or body portion formed to receive a lock which may be applied in any well known manner to hold the lever in an operative position, or, as shown in the drawings, it may be sealed or locked in an operative position by means of a staple or eyebolt h, fixed in the door in position to entera corresponding opening in the vertical arm f when the lever is in locking position.

I prefer to apply the lever to the upper lefthand corner of the door with its upper offset portion projecting slightly beyond the edge of the same. In this position the end of the lever may be bent `to adapt it to be used with any particular form of track that may have previously been applied to the car.

While I have shown and described the door .sustained by rollers traveling on tracks it will,

of course, be understood that any othersupporting and guiding devices may beemployed and that various changes, which may suggest themselves to the skilled mechanic may be adopted provided the operation of the devices iS substantially as described.

Having thus described my invention, what I claim is` .1. The combination with the car and its sllding door, of the rack-bar secured to the car over the door and parallel to the line of movement thereof, and an angular lever compr1s1ng two arms of unequal weight pivoted at, or near, its angle to the door adjacent t0 the bar, the lighter arm provided with a tooth adapted to engage the rack-bar, and the other having the preponderance of weight adapted to serve as a handle in fastening and unfastening the door, and in opening and closing the same and operating by gravity to fasten the door.

2. The combination with'the car and its sliding door, of the rack-bar secured to the car across the top of the door and parallel to the line of movement thereof,an angular lever pivoted at or near its angle to the door adj acent to the bar, one arm provided with a tooth adapted to engage the rack bar and the other with means for engaging a fastening device on the door, and serving also as a handle in fastening and unfastening lthe door and in opening. Y

3. The combination with the car and its sliding door, of the rack bar secured to the car across the top of the door and parallel to the line of movement thereof, an angular lever pivoted at or near its angle to the door adjacent to the bar, one arm provided with a tooth adapted to engage the rack bar and the other with an eye or opening to receive a holding device, and a staple or eye-bolt projecting from the door adapted to enter the eye in the lever and to receive a lock for securing the lever in locking position.

In testimony whereof I hereunto set my hand, this 22d day of March, 1892, in the pres- 4o ence of two attesting witnesses.

WILLIAM W. I-IALEY.
