tendit giant @anni @dus CHARLES BIRD, OF LOWER MERION TOWNSHIP, ASSIGNOR TO HIMSELF, CHARLES JT. FIELD, AND T. I.

SARGEN'I, OF PHILADELPHIA, PENNSYLVANIA.

Letters Patent No. 112,210, dated February 28, 1871.

IMPROVEMENT IN DOOR-CHECKS.

The Schedule referred to in these Letters Patent and making part of the same.

I, CHARLES BIRD, oi Lower Merion township, county of Montgomery, State ot" Pennsylvania, have invented a Device for the Adjustment and Retention ofr Doors, of which the following is a specification.

Nature and .Object of the Invention.

My invention consists of a device too fully described hereafter to need preliminary explanation, for retaining a door in an open or partly open condition, and at the same time permitting the door to be readily adjusted so as `to be inore or less open.

Description of the Accompanying Drawing. Figure l is a front view of my device for retaining doors;

Eigures 2 and 3, plan views of the same; and Figure 4, a view of part of the device.

General Description.

A represents part of th door of a railroad-car, hinged at a, in the usualmanner, to the endB of' the body of the car.

To a stud, b, secured tolthe back of the door,'is hinged an arm, D, which passes through and s guided by a plate, E, secured to the body of the car, and to lugs on this plate are connected arms d d, bent, as

latter yielding to the corrugations, and closing on and griping the bar between the corrugations with such force as to retain the door after to the desired extent, and prevent it from being moved by the motion of the car or by the wind, the door yielding only on the application of considerable force, when it has to be entirely opened or closed or to be adjusted to another position, and there retained by other oorrugations o f the bar.

In thepresent insta-nce the arm D has at the back and for its better guidance a rib, h, adapted to a slot in the plate E, as best observed in fig. 4.

The bar may have corrngations on one edge only, the other edge being straight, but I prefer the corrugations on both edges.

Although I have alluded to my invention as applied to the adjustment and retention of the doors of railroad-cars, it will be evident that Ait may be applied with advantage to other doors, or to the lids of boxes or trunks.

Claims.

l The bar D, lhinged to a door, and having corrugations j; in combination with axed plate E, for guiding the bar, and elastic arms d, adapted to the corrugations, all substantially as set forth. l

In testimony whereof I have signed my name to this specification in the presence ot' two subscribingr witnesses.

GHAS. BIRD.
