DU M P-CAR.

SPECIFICATION forming part of Letters Patent No. 476,366, dated J une '7, 1892. Application tiled October 22, 1889. Serial No. 327,816. (No model.)

To all whom it may concern:

Be it known that I, ROBERT S. COX, a citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented certain new and useful Improvements in Dump-Cars, ot which the following is a specification.

This invention relates to dump-cars; and it consists in the construction, combination, and arrangement of parts, as hereinafter shown and described, and specifically pointed out in the claims.

In the drawings, Figure l is a semi-sectional side elevation, Fig. 2 is a plan view, and Fig. 3 is a cross-sectional view on the line fr a of Fig. l., of one ot my dump-cars complete. Fig. i is a view similar to Fig. 3, showing a slight modification in the construction. y

A represents the floor-frame, A2 the side fram es, and A3 the trucks, of a car, these parts being ofthe ordinary construction, except that the floor is provided with openings d along the sides between the trucks, these openings being covered by.downwardlyopening doors or drops B. These doors B are each hinged by one edge to the licor-frame, as shown, and supported by chains D by their free edges, the chains passing upward over rods or windlasses E to arms E2 or to other devices whereby the doors may be elevated or allowed to be depressed. The openings a will generally be arranged between the trucks, so that the material being discharged from the car will not fall upon the axles or truck-frames.

In Figs. l, 2, and 3 the interior of the carbody is formed hopper-shaped by inclined sections F, which cause all the contents to run down through the openings a when the doors B are opened, while in Fig. 4: the interior is without these inclined sections.

I.Vhile the presence of the inclined sections renders the discharge of the contents of the car more convenient, I do not `wish to be limited to their use, as the car is operative without them.

The openings d may be of any required size and may be of any desired number, but will occupy the same relative position with relation to the bottom and sides of the car-viz., along the sid es-as the location of these openings, and the manner in which they are employed is one of the principal features ot` my invention.

This class of du mp-cars are employed more particularly in railroad-graditi g work in transporting earth and similar material and in discharging it quickly at whatever point desired.

By arranging the discharge-openings a in the bottom along the sides I am enabled to discharge the material from the cars close to the .outside of the track when the doors B are hung by their inner edges, as in Fig. 3, orbetween the rails when the doors are hung by their outer edges, as in Fig. et.

In grading railroads the earth is required to be discharged as close to the rails as possible, either inside or outside, to produce the best results and avoid the necessity for rehandling by shoveling or otherwise. In completin g fills around trestle-work and other similar locations this ability to discharge the earth close to the track or between the rails is of especial advantage, and the extreme simplicity of the construction of my car and the method oi' accomplishing this result render it of great importance.

The doors B by the method of supporting them serve as chutes to the earth when being discharged, so that it is conducted from the car in any desired quantity or with any desired degree of force.

I have shown in Figs. l, 2, and L and the left of Fig. 3 the doors B, adapted to be actuated by chains D, connecting them to horizontal shaft E", the revolution of the rods winding the chains upon the rods as drums, while on the right of Fig. 3 I have shown an arm E2, attached to the shaft E', and with a chain D connecting its outer end with the doors B, the revolution of the shaft E causing the outer ends of the arms to rise and fall and thus open or close the door B; but I do not wish to be limited to any specific method of operating the doors, as Iam aware that they may be operated by other suitable devices than those shown.

Having thus described my invention, what I claim as new isl. In a d ump-car, the combination, with the frame and inclined bottom, of downwardlyopening doors hinged to the bottom, a longitudinally-arran ged shaft j ournaled in the ends IOO ot the car above the doors, and chains directiy connecting the shaft and free edges of the doors, substantially as and for the purposes described.

2. In a dump-car, the combination, with the frame and inclined bottom, of downwardlyopening doors hinged at their inner edges to said bottom, a longitndinally-arranged shaft journaled in the ends of the car in vertical alignment with the free edges of the doors, and chains secured to said free ends, having their upper ends wound around and secured to the shaft, whereby upon the unwinding of the chain the doors are lowered, substantially as and for the purposes described.

3. In a dump-car, the combination, with the frame and inclined bottom, of hinged doors forming chutes hinged at their inner edges to ROBERT S. COX.
