T0 @ZZ whmn it may concern.'

Be it known that I, Ofr'ro W. MEissNnR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dump-Cars, of which the following isa specification.

The invention relates to that class of dumpcars known as Rodger ballast-cars, and

`particularly to the construction and arrangement thereof by which such cars may be made convertible and used either as a center dumpcar of the Rodger type or as a platform-car, all of which will more fully hereinafter appear.

The principal object of the invention `is to provide a simple,economical, and efiicient convertible dump-car.

The invention consists principally in a dump-car in which there are combined a supporting-framework, a V-shaped hopper portion secured thereto and extending1 below the same lengthwise thereof and with its apeX at or near the longitudinal center of the car and formed in two portions-a lower V portion and an upper foldable portion-secured to the vsupporting-framework of the car above the same, so as to form a portion of the inclined sides of the V-shaped hopper when in one position and a portion of the flat part of a platform-car in a second position, and side boards pivotally secured to the framework of the car and adapted to form the sides of a dumping hopper-car or be folded outwardly and downone inclined side, CZ, rigidly secured to the framework and the other side, e, pivotally secured thereto at f, so as to form a discharging-door. The upper portion of this hopper is made of two swinging sections g and ZL, pivotally secured to the supporting-framework of the car above the same, so as to swing upwardly and outwardly to complete the inclined side of a t-shaped hopper when in one position-that shown to the right of the figureand to be laid in a flat plane and complete the flat portion of a platform-car when in a second position, as shown to the left of the drawing.

Y Swinging side boards made in two foldable portions c' and fare provided and pivotally secured together at 7c, being also pivotally secured to the framework of the car above .the same at Z. These joints,which form thepivotal connection between the foldable portions of the side boards, aremade in the form of crulejoints, 7 so as to permit such portions to be folded back upon one another or arranged in continuous form, as desired. The side boards are so constructed and arranged that they may be 'raised to an upwardly-extending or vertical position and are provided with recesses m to receive the upper edge of the swinging hopper-sections and hold the same in their inclined position. To lockA them in 'such position, they are provided with Vlinks 71 and the foldable side boards with chain-hooks p and q, by which such parts are secured together and Y sustained in the desired relation, so as to form a center-dump hopper-car. To permit the formation of a platform-car, the foldable side boards are released from their interlocking engagement with the swinging hopper-seetions and the upper part j folded back upon the lower part t', so as to permit its chainhook to engage a locking-link 7. A hook t is provided on the lower part of the supportingframework of the car and arranged to engage with an eyebolt u on such board and hold the parts in position, as shown to the left of the figure.

To open and close the discharging-door of the hopper portion, the usual rock-shaft Q; and chain mechanism u are provided and adapted to be operated in the usual manner, all of which is well known and understood by those skilled in the art.

I claim- 1. In a convertible dump-car, the combination of a supporting-framework, a V-shaped hopper portion extending lengthwise of and below the same with its apex at or near the longitudinal center of the car and formed in two portions-a lower V portion and an upper foldable portion secured to the supportingframework of the car above the same so as to form a portion of the inclined sides of the V- shaped hopper when in one position and a part of the fiat platform of the ear in asecond position, and swinging side boards pivotally secured to the framework of the car and adapted to form the sides of a dumping hopper-car or be swung outwardly and downwardly to permit the formation of a platform-car, substantially as described.

2. In a convertible dump-car, the combination of a supporting-framework, a V-shaped hopper portion extending lengthwise of the car and formed in two portions-a lower portion secured to the framework of the car extending below the same and an upper portion formed of two swinging sections pivotally secured to the framework of the car above the same so as to complete the inclined sides of the V-shaped hopper in one position and the flat portion of a platform-car in a second position, foldable side boards pivotally secured to the framework of the car and arranged to be placed in a vertical position to receive the upper edges of the swinging hopper-sections when in one position and to be folded outwardly and downwardly in a second position,

and means for securing the foldable side boards to the swinging hopper-sections to hold both of such parts in desired relation, substantially as described.

3. In a convertible dump-car, the combination of a 'supporting-framework, a V-shaped hopper portion arranged lengthwise thereof and made in two parts, a lower V-shaped portion secured to the framework of the car and below the same, and an upper portion formed of two swinging sections pivotally secured to the framework of the car above the same so as to complete the inclined sides of the V-shaped hopper in one position and the flat portion of a platform-ear when in a second position, and swinging side boards made in two foldable portions pivotally secured to the framework of the car and having recesses arranged to support the free edges of the swinging hopper-sections in one position and be folded together and swung outwardly and downwardly to permit the formation of a platform-car when in a second position,- and means for securing both portions of the foldable side boards to the swinging hopper-sections to sustain the parts in the desired relation, substantially as described.

4. In a convertible dump-car, the combination of a supporting-framework, a V-shaped hopper arranged lengthwise thereof and made in two portions-a lower V portion having one fixed and one swinging section extending below the supporting-frame and an upper portion formed of two swinging sections pivotally secured tothe framework of the car above the same so as to complete the inclined sides of the V-shaped hopper in one position and the flat portion of a platform-car in a second position, swinging side boards made in two foldable portions pivotally secured to the framework of the car and having a recess in which the upper edges of the swinging hopper-sections rest, rule-joints forming the pivotal connections of the swinging side boards and foldable portions, and link-and-chain mechanism for holding the swinging side boards and hopper-sections in desired relation, substantially as described. 4
