DOOR FOR GRAIN-CARS.

SPECIFICATION forming part of Letters Patent No. 403,366, dated May 14, 1889.

Application filed October 4, 1888. Serial No. 287,180. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. OBoRN, a citizen of the United States,and a resident of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Grain-Doors for Cars; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention, and is a vertical section taken through the center of the door. Fig. 2 is a front view.

This invention relates to improvements in grain-doors for freight-cars and it consists in the construction and novel combination of parts, as hereinafter set forth.

Heretofore grain-doors have been made with a sliding section at the bottom, which is objectionable, as it is difficut to open. In my invention the bottom section is designed to swing outwardly, and will open by the pressure of the grain after the locking bolts or slides shall have been drawn.

Referring to the drawings, A designates the side of a freight-car of the usual construction, and having the ordinary sliding door on its outer side, which door, however, it is not deemed necessary to show in the drawings.

B represents the upper section of the graindoor, having one of its ends formed with an acute angle, to which the butts or hinges a are secured, which have their pins seated in the sockets b, secured to the inner side of the car.

It will be observed that the sockets b are placed out of a vertical line with each other at an angle corresponding to the angle at the end of the door, so that when the door is opened its free end will swing upward so as to clear the grain that may be piled at the end of the car. A hook, c, engaging with a suitable eye or staple in the car, serves to hold the door open, and also serves to hold it closed when engaged with the staple cl.

0 shows the lower section of the door hinged or otherwise secured to the section B, so as to swing outwardly and upwardly through the doorway and allow the escape of grain, and to make the edges perfectly tight the flexible rubber strips D are secured thereon. Sliding bolts or plates E at the ends of the swinging section are designed, when projected against the inner sides of the car, to prevent the opening of the section by pressure of the grain.

This door as constructed may be transferred from one car to another, as it is only necessary to lift it from the sockets and swing it in the sockets provided in another car.

Having described my invention, what I claim is- 1. A grain-door having its upper section formed with an acute-angle hinged end, and provided with an outwardly-swinging lower section folding back upon said upper section, substantially as specified.

2. In a grain-door for cars, the combination of the upper section having the acute-angle end, the butt-hinges, and the outwardlyswinging lower section having the flexible strips, substantially as specified.

3. In combination with the car, the graindoor adapted to swing on the sockets I), placed out of a vertical line with each other, the hinged lower section adapted to swing outwardly through the door-opening, and the locking-plates, substantially as specified.

In testimony whereof I affiX my signature in presence of two witnesses.

GEORGE W. OBORN.
