ISAAc v. KELLY, oF HUNTINGTON, WEST VIRGINIA.

CAR-DOOR.

SPECIFICATION forming part of Letters Patent No. 522,019, dated June 26, 1894, Application filed September 8,1893, Serial No. 485,068. (No model.)

exact description of the invention, such as .o is to protect the outer or car door proper from will enable others skilled in the art to' which 1t appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, whIch form a part f this 'specication My invention relates vto improvements in grain doors and adjacent parts of a car by which they are protected.

The doors'are designed tQ be employed on the ordinary boX, or freight car when used for transportingvgrain inbulk. The object the pressure of the grain, and conceal it from j evil disposed persons who oftentimes approflipriate the. ordinary grain doors for fuel. Doors having slmply a sliding movement are {i} found to be objectionable inasmuch as when the car is to be unloaded, the door must either be raised or slid back; This is difficult to do by reason of the pressure of the grain against them, therefore they are often cutout and destroyed.

My invention aims to overcome these objections by providing a door which can be opened outwardly to unload the car and slid back out of the'way when the car is to be loaded with other freights, or is not in use.

With these ends in view my invention consists in certain features/of construction and combination of parts, which will be hereinafter ,described and claimed.

Figure 1, is a central longitudinal section of a car constructed in accordance with my `invention showing the same as being provided -tion andpartial section of the door post and adjacent parts.

In the said drawings the reference'numeral 1 designates the sills which support the floor of the car, 2 the plate which su pports'the roof,

3 the intermediate posts, and 4 the door posts. The door posts 4, are cut away from a point about four and one-half feet from the I'loor, on the inner sides, to the lower ends forming in connection with the inner walls 5, of the car, a way 6, for the sliding door 7. These inner walls 5, consist of a number of boards secured to the intermediate posts, and at the door posts, are secured to a verticalangle bar 9, which b'ar at its lower end is bent upwardly at right angles, forming a short arm 10, which arm is bolted to the car floor. The flange of bar against which the ends of boards or inner wall abut, is cut away from that part which is bent up as described, the bar being left entire to the bottom of inner wall or lining of car. The upper end of said angle bar is secured to door post above the point where the post is cutaway. To the insideof the boards forming the inner wall, at their ends, and opposite the angle bar, is secured by wood-screws cured to door post and iirst intermediate post,`

against which post the vertical board 14 abuts when the door is put away in its housing. The door posts at the cut-away portion are formed with slots 17, aligned with said hinges so as to permit the latter to slide past said posts when the doors are closed. At the rear ends, the boards 14, are provided with arms 18, the free ends of which are bent outwardly at a right angle, forming stops to limit the movement of said boards when the doors are slid toward the center of the car, to close them. Working in staples 19, securedto door posts, are vertically movable pins 20, provided at their upper ends with ropes 21, by

IOC)

which they are connected to said posts. When the doors are put away, these pins drop down in front thereof and prevent them from be- 1ngshut,while, when said doors are shut, they drop into holes in the upper edges of the boards 14, and thus hold, or lock the doors in such position. The doors may also be provided with locking bars for securing them together when closed. These locking bars are not illustrated in the drawings, but may be of any of the ordinary or usual constructions.

The operation will be readily understood. When thecars are to be loaded the doors, and extensions to which they are secured are pushed back or rearwardly into the housing formed by the inner walls of the car, and the horizontal guide bars, thereby providing an opening at the center of the car. When the car is loaded the doors are slid toward the center of the car, and locked together by the locking bars and the pins 20.

To unload the car, the doors are unlocked and opened outwardly like an ordinary door, turning on their hinges so that access can be had to the interior of the car. icient quantity of the grain has been removed, the doors can be closed inwardly, and then slid back in their housings. In this position, as they have no outwardly projecting parts, there is no liability of their being injured in any way.

While my invention is more especially designed for use in connection with cars carrying grain in bulk, it may be employed for transporting the same in bags or other packages and also be used with cars carrying other merchandise.

Having thus described my invention, what I claim is l. In a grain or other car, the combination with the intermediate posts, the door posts .cut away on their inner lower sides and with the inner walls of the car forming ways, of the outwardly opening and slidable doors and the extensions or boards to which said doors are hinged, working in said ways, substantially as described.

2. In a grain or other car, the combination with the intermediate posts, the doorposts cut away on their inner lower sides and with the inner walls of the car forming ways, of the outwardly opening and slidable doors, the extensions to which said doors are hinged, working in `said ways, and the horizon tal guide bars secured to said posts, substantially as described.

3. In a grain or other car, the combination with the plates and sills and intermediate posts, and the door posts, cut away at their lower portions, of the inner side walls, the angle bars to which said walls are secured, the flange of said angle bar that stands at right When a sut-` angles to said door posts being cut away at the bottom and the remaining portion from which it was cut bent upward at right angles and secured to the iioor of the car, said bar being left entire to the bottom of the inner wall of car, the vertical bars secured to said wall and to the car floor, and the slidable doors and extensions, substantially as described.

4c. In a grain or other car, the combination with the intermediate posts, the door posts cut away at their lower inner sides and the inner walls, of the outwardly opening and slidable doors, the slidable extensions to which said doors are' hinged, having a hole in their upper ends, and the vertically movable locking pins secured to the door posts and adapted to engagewith the holes in said extensions by gravity, substantially as described.

5. In a grain or other car, the combination with the intermediate posts, the door posts cut away at their lower inner sides, and the inner walls, of the slidable doors and extensions, the hinges secured to said doors and extensions, the outer leaves of which have their ends bent at a right angle forming stops which engage with the door posts when the doors are open, substantially as described. u

6. In a grain or other car, the combination with the intermediate posts, the door posts cut away at their lower inner ends or sides` and the inner walls, of the slidable extensions `having holes in their upper ends, the slidable doors, the hinges connecting said doors and extensions, the outer leaves of which have their free ends bent at a right angle forming stops adapted to engage with the door posts, and the vertically movable gravity pins connected with the door posts, and adapted to engage with the holes in said extensions, substantially as described.

7. In a grain or other car, the combination with the intermediate posts, the door posts cut away at their lower inner sides, and the inner walls, of the slidable extensions having holes in their upper ends, theslidable doors, the hinges connecting said doors and extensions, the outer leaves of which have their free ends bent at a right angle forming stops adapted to engage with the door posts, the vertically movable gravity pins connected with the door posts and adapted to engage with the holes in said extensions, and the horizontal guide bars secured to said posts, substantially as described.

In testimony whereof Iattix my signature in presence of two Witnesses.
