DUMP-CAR.

Specification of Letters Patent.

Patented Feb. 20, 1912.

Application filed September 27, 1909. Serial No. 519,865.

Be it known that I, HARRY S. HART, a citizen of the United States, residing at Chicago, in the county of Cook and State of Ilhnois, have invented certain new and useful Improvements in Dump-Cars, of which the following is a specification.

The object of my invention is to provide a car of the type known as the Hart convertible car with movable sides so formed that they may be either adjusted to a vertical position or to an inwardly and downwardly inclining position.

Cars of the type referred to are illustrated in Patents Nos. 689,583 granted to Harry S. Hart, December 24, 1901, and 827,632, Harry S. Hart and others, July 31, 1906.

Cars of the type to which my invention is applied are provided with a central longitudinal hopper, flat floor sections extending outwardly from the hopper to the sides of the car and vertical sides'and adjustable ends. Means are provided for covering the central hopper in order to transform the car into an ordinary gondola car, and to so adjust the parts as to uncover the central hopper, to incline the ends inwardly toward the central hopper, and in some instances to provide upward prolongations of the sides of the central hopper.

The nature of my improvement in, these cars will be apparent from the following description and claims, taken in connection with the accompanying drawings, in which- Figure 1 is a. cross sectional view embodying one form of my invention. Fig. 21s a detail of the upper end of a flap or apron located between the side doors. Fig. 3 is a view of the structure adjacent one of the side stakes, looking from the inside of the car.

In cars of the type to whichnuy invention is applied, the sides are formed of doors hinged at their upper edges. It my pres ent purpose to so arrange the-structure that these doors may be moved inwardly on their hinges to slope in the direction of the walls of the hopper bottom to form prolongations thereof.

In the car illustrated the superstructure comprises side stakes 26 rigidly connected to the underframe and carrying at their upper ends side rails 25. In the present instance 1 have shown these side rails built up from an I- beam and a wooden strip bolted together. The doors 27 are hinged upon loo s 10 se -cured to the under sides of the ralls- 25 by means of bolts 11 which secure the two parts of the side rails together. The doors 27 may eitheroccupy a vertical position as shown at the right of Fig. 1, may be swung inwardl to an inclined position as shown at the le t of Fig. 1, or may swing outwardly to permit the contents of the car to be discharged through the sides thereof by means of a plow, or otherwise. The floor of the car comprises stationary horizontal sections 6 proj ecting inwardly from the car sides to the outer edges of the central hopper. Aprons 35 are hinged to the underframe of the car along the longitudinal edges of the central hopper and may be swung downwardly to a horizontal position as shown at the right of Fig. 1, covering the central hopper and forming a flat bottom car, or may be lifted to the inclined position shown at the left of Fig. 1. When thejparts are adjusted as shown-at the left of Fig. 1, a center dump hopper car is'formcd. This adjustment is effected by moving the side sections 27 inwardly sufficiently to permit the aprons 35 to be moved to a position outside of said sections 27, as shown at the left of Fig. 1. When so adjusted, the aprons 35 are held in the position. shown at the left of Fig. 1 by means of braces 30, and the side sectlons 27 are in turn supported. upon the aprons 35.

The central hopper may be of a form now in common use, comprising a. stationary side 12 and a hinged side 13, hinged at 14 to the underframe. A chain 15 attached to the swinging section 13 at one end is at the other end attached to a winding shaft 16. Suitable means for rotating the windin shaft 16 permit the section 13 to be release for the purpose of dumping the load, and upon rotation of the winding shaft 16 in the Unless some provision be adopted, spaces Cl'i would beleft between the doors 2'? when adjusted to the position shown. at the left of Fig. 1, such spaces being of the width o'l the side stakes which separate the doors. 1 have, therefore, showi'i aprons 2E3 hung upon the loops 1.0 which sup mrt the doors 2?, these aprons being of smnewhat greater width than the Side stakes and lilppll'lg over the adjoining edges of the dome 27. The upper ends of the aprons 28 are provided with eyelets, as illustrated in Fig. 2, these eyelets engaging the loops l0. llhen the doors 27 are moved inwardly to the pos .ion shown at the left of Fig. 1, the aprons 28 will be carried with them, thus affording a closure of the spaces between the doors When the doors 27 are adjusted vertically shown at the right of Fig. 1, the aprons 538 will hang fiat against the doors, and when the doors aremoved outwardly, the aprons will be left behind and lying against the innerfaees of the side stakes.

It will he appav out from the 3ftthat I have provided a car whicl'i .u adjusted as an ordinary flat bottom ear with vertical sides and ends, and a laori zontal floor, and'that when so adjuswi the load may he "d th the doors by 1': i w or cl The car may also be adjusted to pruide a eentral longitudinal hopper with slop Zing inwai ly and downwardly from their upper er l. dump car coi'nprising side walls justahle to an inwardly and down -vainly sloping position, and a central loi'igitudin'al hopper.
