CAR-DOOR.

SPECIFICATION forming part of Letters Patent No. 274,107, dated March .20, 1883. A plication. filed October 26,1882. (No model.)

. tain new and useful Improvement in Car- Doors, of which "the following is a specification, reference being had to the accompanying drawings. g Y

My invention relates more particularly to that class of doors which is used in cars when carrying grain, being required independently of the ordinary door, which is all that is necessary in carrying ordinary freight. There is generally used for this purpose a temporary door, which usually answers the purpose for but a single trip.

My invention consists in the novel construction of the hinge and the method of hanging the door.

The drawings represent the inside of a car, Figure 1 showing the door closed, and Fig. 2 showing the position of the door as folded back and secured when not in use, like letters indicating like parts in the two figures.

The door is constructed a little less than half the height of the car, and is hinged to the door post or support at one upper corner only. The hinge, as constructed, forms a ball-andsocket joint. It consists of a ball, A, with a shank,a, by means of which it is secured to the doors, and two retaining-sockets, B B, each consisting of a lug containing a concave cavity and provided with a shank adjusted to clutch and retain the ball A, and secured to the door post or support by means of the shanks. The shank of one of the sockets may, if desired, be provided with slots, through whichthe retaining screws or bolts pass, so that the socket may be adjusted to regulate the friction of the joint or take up its wear. Stops or brackets 0 care secured on the floor of thecar to retain the bottom of the door when'closed. Through the operation of this hinge the door may be folded back against the side of the car in the position shown by the dotted lines in Fig. 2, and turned up in the positionin which the door is shown in that figure,where it may be secured by the catch 01. As freight-cars are ordinarily constructed the door in this position lies closely against the side of thecar, and

thus offers no obstruction to the available space of the interior. The hinge permits the door to be brought to any desired position, which fact affords many advantages. Being easily raised to the position shown by the dotted lines in Fig. 1, it allows the dumping of the grain, avoiding the difficulty of opening or removing the door when the grain is pressing against it, encountered in other forms of doors.

It is apparent that the hinge might be applied by securing the ball upon the jamb-post and the retaining-sockets upon the door, and that the hinge might be applied to many other uses than the one particularly mentioned, in all which cases my invention would be embodied.

Havingthus described my invention, what I claim as new, and desire to secure by Letters .Patent, is-

A hinge consisting of a ball, A, provided with a shank for securing the same to the door orjamb, in combination with the two retaining-sockets B B.
