LUMBER-[200R FOR RAILROAD BOX-CARS.

SPECIFICATION forming part of Letters Patent No. 280,395, dated July 3, 1883,

Application filed December 6, 1882.

To all whom it may concern:

Be it known that I, GEORGE B. NIoHoLs, of Galveston, in the county of Galveston and State of Texas, have inventeda new and useful I111- provement in Lumber-Doors for Railroad Box- Cars; and I do hereby declare the following to be a full, clear, and exact descriptionthereof. My invention relates to an improvement in railroad-cars, and it consists in alumber-door situated at one end of the car and provided with devices for preventing rain, snow, or sparks from entering through the space above the door.

on the return-trip were it not that lumber cannot be put in box-cars through the side doors. To enable this difficulty to be obviated and permit of the loading of box-cars with lumber, I form a doorway in the end of the carthrough which the lumber is easilyloaded and unload-.

ed from the car, said doorwaybeing closed by a door and weather-shutter, as will hereinafter more fully appear.

Iwill now describe my invention so that others skilled in the art may manufacture and use the same, reference being had to the accompanying drawings, forming apart of this specification, in Wl1l(3h Figure 1 is afront elevation of the end of the car, showing the door. Fig. 2 is arearv elevation of the same. Fig. 3 is a longitudinal section of the door and end of the car, and Fig. 4 is a front elevation of a part of the same.

Like letters refer to like parts wherever they occur.

In the end of the car is a doorway, k, of sufficient size to allow of lumber being passed through the same into the car.

- On each side of the doorway k, on the outside of the car, are strips which form ways k [0 in WhichthedOOr slides up and down, so as t "closeand open the doorway is.

At the lower end of the doorway k is a sill, G, upon and against which thelower end of the door rests when shut. Passing through the sill G is a bolt, H, around which is a spiral spring, I, the ends of which spring bear against a plate, L, on the inner face of the sill G, and a pin, h, which passes through the bolt H.

(No model.)

a shutter, A. This rod B is secured to the shutter beyond the middle portion thereof, so that by the force of gravity the shutter will tend to assume aperpendicular position. The leaf or part A of the shutter, being heavier than the part A falls down upon and extends over the top edge of the door E, while the small part or leaf A rises and comes in contact with the weather-strip G, which is attached to and extends down from the upper portion of the casing D. When the door is opened it lifts the shutter A, which turns on its axis B in the.

casing D and allows the passage of the door without interfering with the movement of the same. WVhen the car has been loaded, the door is shut by releasing the same, and it falls of its own weight, or is drawn down. Theinclined plane f on the lug f strikes the end of the spring-bolt H, pushing it in, so as to allow the end of the door to pass the same and rest on the sill G. The end of the bolt H, then being opposite the recess F, is released and passes into the recess, being moved by the spring I, therebylocking the door automatically in such a manner that it can only be unlocked from the inside of the car by withdrawing the bolt H from the recess F. The shutter A, resting on and over the top end of the door, effectually prevents any water or sparks from entering the car between the top of the door and the doorway, and the portion A of the shutter bearing against the strip 0 makes a tight joint at that point.

The advantages of my invention are the saving of time and labor by the easy transportation of lumber inbox-cars; and as my improved door is perfectly tight it does not injure the car for the purpose of the transportation of other merchandise.

I am aware that a sliding door for box-cars has heretofore been provided with a movable IOO weather and fire strip pivoted 011 the rear end of the door to swing across and close the crack between the door and car when the door was closed, and do not herein claim, broadly, the combination of a sliding door and pivoted strip; but,

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a box-car, the combination, with the end thereof, of a vertically-sliding door and a shutter pivoted above the door, substantially as and for the purpose specified.

2. In a box-car, the combination of a vertically-sliding door and an overbalanced shutter pivoted in the frame above the door and actuated thereby, substantially as and for the purpose specified.

3. In a box-car, the combination of a sliding door provided with a lifting-catch having a recess and an inclined face, with a spring-bolt arranged on the inner face of the door-frame, substantially as and for the purpose specified.

4. In a box-car, the combination, with a vertically-sliding door, of an overbalanced shut ter pivoted abovethe door, and a spark and weather strip secured to the door-frame above the pivoted shutter, substantially as and for the purpose specified.

5. The combination, with a sliding door, of 30 an overbalanced shutter pivoted on the doorframe in the path of the sliding door, substan tially as and for the purpose specified.

6. The combination, with a sliding door, of

a shutter pivoted on the door-frame in the 35 GEORGE B. NICHOLS.
