THOMAS A. BOYERS, OF GAINESVILLE, TEXAS.

GRAIN-DOOR FOR FREIGHT-CARS.

SPECIFICATION forming part of Letters Patent No. 644,701, dated March 6, 1900.

Application filed October 13, 1899. Serial No. 733,608. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS A. BOYERS, a citizen of the United States, residing at No. 612 North Denison street, Gainesville, in the county of Cooke and State of Texas, have invented a new and useful Grain -Door for Freight-Cars, of which the following is a specification.

This invention relates to freight-cars in general, and more particularly to grain-doors therefor; and it has for one of its objects to provide a door which may be operated to close the lower portion of the doorway and which may be raised and swung to one side and held in this position when not in use.

A further object of the invention is to provide a simple means for holding the door in its inoperative position and for facilitating its adjustment.

In the drawings forming a portion of this specification and in which similar numerals of reference designate like and corresponding parts in both views, Figure 1 is a side elevation showing the interior of a car with a door in its inoperative position, its operative position beingindicated in dotted lines. Fig. 2 is a detail perspective of the supporting-hook with which the door is engaged when in its inoperative position.

Referring novto the drawings, 5 and 6 represent the upper and lower beams at the side of the car and which support the roof and floor of the car, and connected with these beams are the door- jambs 7 and 8 at the sides of the doorway.

Adjacent the j amb 8 andinwardly therefrom is fixed a rod or bar 10, which forms a pintle for the door 11, which consists, preferably, of a plate of metal having one end rolled to form a cylindrical eye 11, through which the pintle 10 is passed and upon which pintle the door is adapted to swing and to have a vertical movement. To the outer side of the door is fixed a stop 13 and also guides 14: at opposite sides of an opening 15, which opening is adapted to be closed by a slidable door 16, operating in these guides.

Fixed upon the inner face of the jamb 7 is a keeper 17, behind which the outer edge of the door is adapted to lie to hold it against pivotal movement. Thus when it is desired to open the door, which is swung inwardly, it is necessary to first raise it upon the pintle and the keeper as guides and until the lower edge has passed above the keeper, after which it may be swung inwardly to lie against the inner face of the side of the car, as shown in Fig. 1.

It will of course be understood that in loading a car with grain the grain-door is closed and the grain is shoveled in over the door. When the grain is to be removed from the car, the grain-door is raised and opened to the position shown in Fig. 1 of the drawings. It is therefore necessary to provide means for holding the door in its raised position when opened, and for this purpose a plate 18 is secured to the upper beam 5 adjacent the pintle 10 and has a retaining-hook 20 formed thereon and which extends over the pintle 10 and concentric therewith, the hook being substantially semicircular and separated at its extremity from the jamb 8 by an interspace somewhat greater than the thickness of the door.

At the hinged side of the door is formed an upwardly-extending portion 19, having an opening 2O therein adapted to receive the hook 20.

In practice after the door has been raised from the keeper, as above described, it is further raised until the opening 2O is in line with the tip of the hook 20, and the door is then turned upon the pintle until the hook enters the opening of the door and the door lies fiat against the inner wall of the car, the hook thus preventing downward movement of the door at is hinged edge.

In order to support the outer or free end of the door, an upward projection 22 is formed thereon and has a perforation 23, which receives a pin 24 upon the beam 5 when the door is in the position shown in Fig. 1.

It will of course be understood that in practice the door may have any specific shape and be of any desired material and that other changes may be made in the specific construction shown without departing from the spirit of the invention.

What is claimed is- 1. The combination with a pintle, of a door rotatably and slidably mounted thereon, a hook concentric with the pintle, and an opening in the door adapted to receive the hook to support the door.

2. The combination with a doorway, of a to entersaid opening, aprojection on the door pintle mounted adjacent thereto, a keeper, having an opening therein, and a pin adapted and a door rotatably and slidably engaged to enter the last-named opening and cooper- I 5 with the pintle and adapted to slide into and ate with the hook to support the door.
