PATENT @Enron HORACE L. CLARK, OF RAHWAY, NEW JERSEY.

IMPROVEMENT IN DOORS FOR RAILWAY FREIGHT-CARS.

SpecicationV forming part of Letters PatentNo. 118,514, dated August 29, .1871.

To all whom it may concern: A,

Be it known that I, HORACE L. CLARK, of Rahway, in the county of Union and State o f New Jersey, have invented a new and Improved Car- Door; and Ido hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the saine, reference being had to the accompanying drawing forming part of this specification.

My invention consists in certain improvements connected with car-doors, as hereinafter fully described and subsequently pointed out in the claim 5 also, in an arrangement of devices for securing the lower edge of the door, held by vertical rods at the upper edge against being forced inward and allowing the grain to escape when loaded and swinging' loosely when unloaded or carrying general merchandise.

Figure l is a longitudinal sectional elevation of a car-door having my improvements applied. Fig. 2 is a transverse section, and Fig. 3 is a front elevation of the outside of the door.

Similar letters of reference indicate corresponding parts.

A is the door, consisting of one or more boards or planks, suitably connected together, resting on the floor at one edge and against the end walls of the opening in the car on the insides, but not rising as high as the top of the opening, and connected at the upper edge by plates or bars B, having suitable holes, with the guide-rods C, for

raising to the top of the car. These doors, commonly arranged in this Way, have a small opening, D, through them, near the bottom, for discharging the grain by shoveling it through said.

opening into a spout resting on the car side. A large amount of grain is scattered over the spout and lost by striking against the walls of said opening and the spout outside, and flying away over the spout to the ground. l therefore propose to attach a short cloth spout, E, to the doorV at this opening, to extend suiiiciently beyond the door over the spout commonly used to prevent such scattering, which it does most effectually.

When the hole D is to be closed by the slide F the iiexible spout E is folded back into the hole, as indicated at G and H. A bar, I, may be placed across the hole at the inside of the door to prevent the spout from being turned outside in or being pushed in too far. Y

I propose to have the rods C, on which the door slides upward, spring or incline outward, and form a shoulder at K for the eye-plates B to drop back upon when the door is raised, to hold it snugly' up against the ceiling', the other edge being secured by buttons L.

Commonly these doors are left free, or not provided at the lower edges against being pushed inward, which is objectionable, because they are sometimes forced in by accident and work upward by the jarring ofthe car, and the grain escapes; or, when carrying general merchandise, they may not always be held snugly against the side of the car, and swing and rattle. I therefore propose to have the lower edges provided with bolts or stud-pins M and holes N, iitted in the car-iioor suitably to receive the bolts and hold the door snugly against the car side. The holes are made to extend through the canfloor, so that they will not lill up with grain or other matter 5 and, in connection with the door so arranged, I provide the holding-p=twls X or pins to hold the doors against rising.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with door A, apertured at D and provided with flexible spout E, of the slide F and bar I, to enable said aperture D to be closed and the spout to be folded in the saine plane with the door.

2. The slides B, stationary rods O, and buttons L, combined with and applied to the door A, as described, so as to enable said door to be turned up and supported against the ceiling, as shown and set forth.

3. rlhe stud-pins M on the inner edge of the door and passing into holes N in the car-door, combined with the guides B and pawls X, bearing against the upper edges of the door to hold it rmly in position.

The above specitic'ation of my invention signed by me this 7th day of June, 1871.

HORACE L. CLARK.
