GRAIN- SPECIFICATION forming part of Letters Patent N o. 271,957, dated February 6,

DOOR.

`Application tiled J une 28, 1882. (No Inodel.)

To all whom it may concern:

Be it known that I, ROBERT J. WALKER, of Girard, in the county of Macoupin and State of Illinois, have invented a new and Improved Grain-Door, of which the following is a full, clear, and exact description. y 4

My invention relates to improvements in doors for grain-cars; and it consists in a door hinged to a swinging plate to adapt it to be swung upward edgewise and against the side `of the car when not in use; and it also consists in the peculiar construction and varran gement of parts, as hereinafter fully. described,mh

and pointed out in the claims.

Reference is to be had to tbe accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both thegures.

Figure l is a perspective view of a portion ofthe inside of a car-body having my improved grain-door applied to it, and Fig. 2 is an exterior side elevation of the door.

I make the door in two parts, a and b, which l hinge together by inside hinges, o, preferring to groove the edge of one part, as at d, and to correspondingly curve the edge of the other` part to lit closelyin the groove and makeatight joint, although square edges may be employed. Inside of the door-jainb I hinge the part a of the door, by a pivot, e, at the top, in a plate, f, which isalso pivoted at g in the top of the post h and in the door-jamb. The lower end of the door has a similar pivot, i, lodged in a slot,j. Both of these pivots e and t' are located a-suitable distance from the `edge lc to allow itto swing into a groove, l, in the side of post h, said edge k being curved to iit snugly in the groove, which is to be correspondinglyformed. 'The pivot gis to be slightly lower than the top of the door, so as to cause the hinge-platef to draw the door down tightly on the floor. The edge m of doorb is slightly curved to swing into a correspondingly-curved groove in the post n, and the top of said groove is beveled at o, so that the beveled corner p of the door will be borne down tightly on the door.

The door is fastened'shut by the hasp g and pin ton the outside. If desired, the slot j in the oor for the pivot i may be elongated and suitably sloped on the bottom to allow the door to swing upon the pivot g into the position represented by the dotted lines and lodged on the hookstud u when the door is not required to be shut.

I am aware that car-doors made in two parts and hinged together have been secured to sliding hinges; and I am also aware tbatdoors hinged together and sliding in ways of the door-jamb are old, and I therefore do not claim such invention.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. A car-door hinged to a swinging plate, substantially as herein shown and described, whereby the door is adapted to be swung upward edgewise and against the side of the car when not in use, asset forth.

2. The combination of the grooved posts h and n Vwith the door made in two parts, a and b, and hinged together, and also hinged to the interior of the door-jamb, substantially as described.

3. The pivots c andi, arranged with respect to edge la ot' the door,.and the grooved post h to enable said edge k to swing into the groove of the post, substantially as described.

4. The door a b, hinged to post h by pivot e, and hinge-platef, said platef being pivoted to the post and doorjamb,substantially as described.

5. The door ab, hinged to post h, and pivoted in the slotyl on the door, substantially as described.

6. The door a b, arranged in the slot j, and on the pivot, substantially as described,'for lodgment on the stud-hook u, substantially as specied.

7. The hinge-platef, arranged with respect to post h and door a for bearing said door on the floor, substantially as described.
