CAR-DOOR.

SPECIFICATION· forming part of Letters Patent No. £93,181, dated February 5, 1884.

Applicntion filed September 13, 1883. (Xo model.)

To all whom it may concern:

Be it known that I, Thomas Lee, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Im5 provement in Car-Doors, which improvement is fully set forth in the following specification and accompanying drawings, in which—

Figure 1 is a perspective elevation of the interior of a car, showing the car-door in polo sition. Fig. 2 is an enlarged cross-view of the door and side of the car. Fig. 3 is an enlarged perspective view of a portion of the floor and side of the car, showing the groove in the floor; and Fig. 4 is a perspective view 15 of the under side of the door itself.

The object of the present invention is to provide a car-door so arranged that it is capable of holding grain of any character, and so constructed that it can be attached to any 20 car now in use; and it consists in providing the sill of the car-door opening with two plates, placed a slight distance apart, and in • equipping .the door with a downwardly-projecting: flange or plate on the under side or 25 lower edge· of the door, which flange or plate is designed to enter the groove or recess formed tby the t wo sill - plates.' The doorjambs within are provided with vertical rods, between which the door is placed, and staples 30 over these rods enter the door near the upper edge, so that the door when raised or lowered will slide on these rods, all of which will now be set forth in detail.

In the accompanying drawings, A repre35 sents the floor of any ordinary box-car, and B the side of the car.

C represents the jambs of the door, and D the door. The jambs C are made in the usual manner, or require no change from the ordi40 nary method of constructing the door-openings. The floor, however, or that part within the doorway between the jambs C C, has a plate, E, sunk therein flush with the upper surface of the floor. The inner edge of this 45 plate projects in beyond the jamb C a distance equal to the thickness of the door. Within the plate is placed a second plate, F, which is provided with, right-angled ends G. The plate G is placed a slight distance from the 50_: plate F, so as to provide a groove, H, between the same. I represents one of a series of holes or perforations from th e under side of the floor, communicating with the groove H, so. as to provide a means for cleaning said groove, or providing for the escape of seeds as they fall 55 into said groove.

The door itself is’ constructed in the ordinary manner, and is equipped on the . lower end with the plate J on the inner side, which plate projects beyond the lower end. The 60 two vertical ends of the door are also provided with plates as wide as the [thickness of the door, and these plates also extend down below the lower edge of the docir even with the plate J. The outer edge, K^z, of these vertical strips 65 also projects slightly, so as to extend over past the edge of the facing-strips G on the inner face of the jamb C. The projecting portions of these plates J K rest in the groove H when the door is in position. On the inner sides of 70 the door-jambs C C are placed two rods, L L, their upper ends extending up to or near the car-roof. The terminals of these rods are bent at right angles and driven into the door-jambs, _: . as shown. The door is placed between these 75 rods, and staples M are driven into the vertical edges of the door at its upper end, which staples slide on the rods L. It will thus be observed that the door when in position is on the inner side of the car, with the body of the so door resting against the facing-strips O' of the jamb, while the vertical strips, K, whose edges K' project, rest against the. jambs C.. The lower ends of the strips K and the lower projecting edges of the plate J rest in the 85 groove H, thus preventing the grain from. forcing its way under the door and gradually raising it, and also keeping the grain from forcing its way out between the door and the jamb, owing to the interposition of the facing- 90 plate C' and projecting edge K' of strip K.

To more securely hold the door in position, it is necessary to have some permanent and easy manner of holding the door on the outside. To accomplish this I provide each side’95 of the jambs with an eccentric plate, N, and secure to the door adjacent thereto a lever, O, which lever is provided on the side with a catch or lug adapted to come in contact with the eccentric, so that the door will, by the ac- 10c.

tion of the lever, be brought snugly up against the jamb and held there.

It is obvious that other means may be employed to hold the door against the jamb than 5 herein shown.

/When it is desired to open the door for any purpose, the levers O are removed from the eccentrics and the door bodily raised, and the lower end swung inwardly and elevated,'as io shown by dotted lines P, Fig. 1. A hook, Q, . secured to the roof of the car, serves to hold the elevated door, as shown.

It will be noticed that the entire area of the door is left free and unobstructed.

I am aware that there are devices provided with recesses and openings in the jamb and floor of the car, and having locking-pieces, connecting-plates, and levers for the purpose of securing the door in position. I do not 2G claim any such feature of invention, but simply the groove in the floor of the opening extending the length of the door, within which the-flange at the bottom of the door fits.
