GRAIN-CAR.

SPECIFICATION forming part of Letters Patent No. 556,768, dated March 24, 1896.

Application led November 29, 1892. Renewed September Z3, 1895. Serial No. 563,390. (No model.)

To all whom it may concern:

Be it known that I, JOHN PEARSON, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Grain-Oar Doors, of which the following is a speciiication.

This invention relates to doors Afor graincars of the kind in which the door is so arranged that it can be temporarily secured t-o prevent the escape of small grain, and also released and swung open so as to allow the discharge of grain, and also when not in use raised and held out of the way.

The objects of my invention are to provide simple and efficient means for temporarily hinging the door, and also to provide simple, compact, and reliable means whereby the door can be held in an elevated position, and also at all times be so connected with the car that it cannot be accidentally detached'and lost.

In the accompanying drawings, Figure l represents in elevation a portion of a graincar with the door lowered and closed. Fig. i? is a section on line a: .cc in Fig. l, with the door raised so as to catch upon the elevated supports hereinafter described. `Fig. 3 is a section on line gj y in Fig. 1. Fig. at is a sectional detail illustrating one of the hooks on the door engaging on one of the recesses in the car.

The door A is provided at its upper corners with pintles B, which are bent back so as to provide hooks b, forming hook-shaped pintle portions projecting laterally to the plane of the door. Thebodyof the car-forexa1nple, the frame C of the doorwayis provided with recesses c, in which the hook-shaped pintles engage when the door is in its lowered position, as in Fig. l. These recesses are countersunk in the sides of the frame of the doorway and have each an inclined wall c, which is in the nature of both side and bottoni portion so as to permit the hook to engage the saine when the door hangs vertically, as best shown in Fig. d. The hook is so formed that the door will be prevented from swinging in one direction by reason of its engagement with the inclined wall c', while on the other hand the door will be permitted to swing in the opposite direction until the ends of its .hook-shaped pintles abut against and are arrested by stops c2, which are conveniently formed by the top walls of the recesses c. The pintles are also provided with eyes b for chains I) orlilre flexible connections which are attached to said eyes, and also connected with uprightguide and retaining rods These chains have sliding connections with the rods, E, and to such end the chains are provided with eyes (l arranged to slide upon the rods in which way the door can be raised when so desired. The rods E are secured at their lower ends tothe car, preferably to the frame, and are arranged for the greater part of their length opposite the sides c3 of the frame, so as to be out of the wayof the door, although as a matter of course they can be applied to the side of a car of any construction. The upper end portions of these rods are bent laterally and extended horizontally and parallel with the side of the car, so as to provide supports e upon which the hooi;- shaped pintles of the door can be hung when the door is raised, as in Fig.

The supports e are arranged preferably in vert-ical alignment with the pintles in order that it will be unnecessary to slide the door laterally or in a plane parallel with the side of the car to bring it into engagement with its support, as is common in inostcars of this description. In order to provide these supports e, the upper portion of each rod is bent forwardly from the car, as at e', then laterally toward the middle of the doorway, so as to provide the supports e, and then back toward the car, as at e?, where the terminal portion of the rod is provided with an eye ei", which is bolted to the car traine or body. As a rcsult of such arrangement the rods E serve as keepers for the door7 which has a flexible and sliding connection with said keepers, and at the saine time said rods or keepers are also adapted to provide elevated supports or keepers upon which the pintles of the door can be hung when the door is raised so as to be out of the way.

In Fig. 2 I have shown the door raised, so as to be hung upon the supports c, and it will be understood that when thus raised and supported the door can be swung upwardly from the vertical position in which it is shown iu said gure, so as to permit any usual or suit- IDO able lip, catch or hook with which its lower edge may be provided to be caught upon any suitable holding device under the roof or top wail of the car. It is also understood that any known or suitable fastening device can be employed for locking the door when it is in a lowered position.

The pintles B can be easily made by bending a rod or they can obviously be cast or forged. The hook shape of these pintles permits them to be readily placed in and withdrawn from the recesses or keepers o, and also permits the door when nnfastened to be swung open to a suitable extent. At the same time this arrangement holds theydoor against swing in the opposite direction.

It will be observed that the door is arranged to swing ,between posts formed by the sides of the doorway, and that the door thus arranged can swing outwardly to a limited extent, so as to permit the outflow of grain, when desired, and hence that the grain can be thus discharged without raising the door at the start.

That l claim as my invention isl. A grain-car having a door provided with hook-shaped pintle portions projecting laterally to the plane of the door, and having the sides of its doorway provided with recesses which receive and hold the hook-shaped pintle portions when the door is in a lowered posit-ion, and stops which prevent the door when thus lowered from swinging in one direction, said recesses being adapted to permit the hook-shaped pintle portions to rock for allowing the door to swing in the other direction, substantially as described.

2. A grain-car provided with a door having hook-shaped pintles, and having recesses forming keepers in which the hook-shaped pintles engage when the door is hung in a lowered position, said recesses being formed to allow the door to swing one way but prevent its swing in an opposite direction, substantially as described.

3. A grain-car provided with a door having pintles B with hook-shaped portions l), and having recesses c formed with a stop c2, and an incline c, for the purpose of limiting the outward swing of the door, substantially as described.

t. The combination of the car having recesses countersunk in the sides of its doorway, and the door having pintles provided with terminal portions arranged laterally to the plane of the door and projecting within said recesses when the door is in a lowered position, substantially as described.

5. The combination of the rods E secured to the car adjacent to the doorway thereof and bent at their upper portions toward one another so as to provide supports c arranged parallel with the plane of the doorway, the door provided with hook-shaped pintles having terminal portions positioned laterally to the plane of the door and arranged to catch upon the portions e of the rods when the door is in a raised position, the car being also provided with recesses in which the hook-shaped pintles engage when the door is in a lowered position, substantially as described.
