CHARLES I. WILLSON, OF SUMMIT POINT, WEST VIRGINIA..

DOOR FOR GRAIN-CARS.

SPECIFICATION forming part of Letters Patent No. 319,371, dated June 2, 1885.

Application filed March 25, 1885.

T0 aZZ whom it may concern;

Be it known that I, CHARLES P. WILLsoN, a citizen of the United States, residing at Summit Point, in the county of Jefferson and State of West Virginia, have invented certain new and useful Improvements in Doors for Grain- Oars, of which the following is a specification.

My invention relates to certain improve ments in grain-cars.

The object of the invention is to provide the separate board sections which compose the door with metal eyes which are open on one side, whereby they may slide on the vertical rods and be detached therefrom; also, to provide vertical guides adjacent to the vertical rods,whereby the board sections are prevented from detachment while in the doorway.

The invention is illustrated in the accompanying drawings, in which Figure l is an outside view of the car-door. Fig. 2 is a horizontal section on the line as. Fig. 3 is a vertical section of one-half or one side of a car, showing the door. Fig. 4 is an inside view showing the position of the door'sections when they close the doorway. Fig. 5 is a View of an end of a section separately showing the sheet-metal tip thereon to protect it. Fig. 6 is a view of the eye attached to each section, and which slides on the rod. Fig. 7 shows the lifting-lug on the lower section.

An ordinary box freight-car, A, has a slid ing door, B. To adapt such cars for carrying grain in bulk provision must be made for 010s ing the lower part of the doorway B, so as to make it tight enough to prevent the loss of grain. Heretofore this has been done by placing boards across the doorway on the inner side and nailing them to the door-frame. This, however, has been a resort of such a temporary nature as to prove both troublesome and expensive.

The door to which my improvements relate consists of separate board sections, each provided with metal eyes and two vertical rods, one each side of the doorway, whereon the eyes slide, whereby the board sections may be raised and lowered to open or close the lower part of the doorway.

My improvements will first be described and then claimed.

At each side of the doorway is a vertical rabbet-shaped guide, 0, which assists to keep (No model.)

the board sections in position as they move up or down.

Adjacent to each guide and partly occupying it is a rod, D, the lower end of which is made fast to the bottom part of car-frame. The upper part of this rod has a curve, 6, which gives it a nearly horizontal direction from the doorway toward the middle of the car, as seen in Fig. 3, where it is made fast. This nearly horizontal part f of the rod is just below the ear-roof g.

The board sections J have near each end an eye, h. Each eye takes loosely about one of the rods D, and is adapted to slide thereon. The end of each board section, preferably, is protected by a sheet-metal tip, 70. (See Fig. 5.) The eyes h, as plainly shown in Figs. 2 and 6, are open at one side, in order to permit their detachment from the rods D. It will be seen by reference to Fig. 2 that both of the eyes on each board section have their open side in the same direction, from which it results that when the board section is moved endwise the open side of the eyes will allow them to disconnect from the rods. As long, however, as the board sections are in the doorway, or the ends of the board sections are confined by the guides O, this endwise movement cannot take place; but when the board sections are raised above the guides and passed over the curves 6 onto the nearly horizontal part f, then the endwise movement may be made.

When it is not desired to have the doorway closed by the board sections, they may be kept stowed out of the way just below the car-roof on the nearly horizontal part f of the rods. To retain them from slipping down in front of the doorway, each side of the doorwayframe is provided with a pivoted hold-up or button, Z, whose free end, when in a horizontal position, projects across the path of the board sections. A stop, m, below the pivoted button prevents its turning down, but it is free to be lifted by a person s finger. It will be seen that in raising the board sections they will pass the hold-up button; but the latter device will prevent them from slipping down.

To hold the board sections down firmly to the floor, another button, a, is pivoted to the side of the doorway-frame. This button must be adapted to allow the board sections to come ICO down, but when all are down, prevent them from rising.

The lowermost board section is provided on the outer side with lifting-lugs P. This is a cast-metal plate to rest against the section, and is attached by bolts. An under shoulder, q, is to receive the end of a lever, such as a crowbar, and the plate 4 below the shoulder is to protect the Wood of the section from the end of the crow-bar. By this means all the board sections, which are held tightly by the lateral pressure of the grain, may be raised from the bottom of the car to allow the grain to flow out under the sections.

Having described my invention, I claim and desire to secure by Letters Patent of the United States 1. A door for grain-cars having in eombi nation a rod extending vertically at each side of the doorway, and separate board sections having eyes which are open on one side, Whereby the board sections may slide up and down on said rods, and also be detached therefrom, as set forth. a

2. A door for grain-cars having in combination a rod extending vertically at each side of the doorway, vertical rabbet-shaped guides 0, adjacent to the rods, and separate board sections having eyes which are open on one side, as set'forth.

In testimony whereof Iaffix my signature in presence of two witnesses.
