Specification of Letters Patent. Patented May 27, 1919.

Application filed October 21, 1918. Serial No. 258,989.

To all whom it may concern:

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 Illinois, have invented certain new and useful Improvements in Dump-Cars, of which the following is a specification.

This invention relates to dump cars.

The object of this invention is to improve dump car construction in a novel and simple manner to increase the capacity thereof and at the same time retain the self-cleaning feature.

This and other objects are accomplished by means of the arrangement disclosed by the accompanying sheets of drawings, in which Figure 1 is a fragmentary side elevation of a dump car embodying my invention;

Fig. 2 is a fragmentary plan view of the same dump car; and,

Fig. 3 is a transverse sectional view of the dump car taken over the trucks.

In these days of extremely congested railway and heavy traflic conditions, the importance of increasing thecapacity of railway cars has become recognized, this probably being especially true in connection with dump cars for carrying coal and other dumpable materials.

In a certain well known type ofdump car, the floor at each end of the car over the trucks includes a long sloping member extending downwardly from the end of the car near the top thereof toward the transverse center of the car to form one wall of a transversely extending hopper, the center of the car being provided with a trans versely arranged A portion including transversely arranged dump doors forming the other wall for each of these hoppers arranged on either side of the transverse center line of the car. In other words, this well known type of dump car includes two transversely arranged hoppers, the walls of which are formed by a transversely arranged A portion in the middle of the car and with long sloping members at the ends of the car, said members extending downwardly and toward the transverse center of the car.

By referring to the figures of the drawings, it will be noted that I have shown a dump car including sides 10, ends 11 and a floor, the floor portion over the trucks, and particularly between the ends 11 of the car and the associated bolsters 12, including A= shaped portions 13. Preferably these A- shaped portions include sloping members 14 which extend from the center of the car over the center sill 15 downwardly and outwardly toward the sides of the car. These downwardly and outwardly sloping members 14 preferably are stationary and connected to the car underfra-me to increase the stiffness and rigidity of the car structure. These downwardly and outwardly sloping members 14 terminate in side exit openings which normally are closed by dump doors 16, which preferably are hinged at 17 along the lower edges of the sides 10 of the car, the swinging edges of the dump doors 16 meeting the lower edges of the members 14 to form a tight seal. The longitudinally extending dump doors 16 at the sides of the car may be operated by any suitable operating mechanism, including shafts 18, preferably carried by said dump doors, and also including chains 19 connecting said shafts with the floor portions 14. By providing this A- shaped floor portion over the trucks, the capacity of the car is greatly increased and at the same time the portion of the load ,over the trucks is effectively dumped to the sides of the car through the openings normally closed by the side dump doors 16, this portion of the car being entirely self-cleaning.

The floor construction intermediate the bolsters 12 includes a central transversely arranged A-shaped portion, the upper part 20 of which is stationary and the lower part of which at each side of the A includes a transversely arranged dump door 21 transversely pivotally hung at 22. This transversely arranged A-shaped portion, including members 20 and doors 21, divides the car transversely into two hoppers 23, only one of which is shown in the figures of the drawings. In the case of each of these transversely arranged hoppers 23, one wall is formed by the transversely arranged members 20 and 21. The other transversely arranged wall is formed by a sloping member 24 which extends substantially from the inner end of the floor portion over the trucks and from the bolster 12, or at a point inwardly therefrom, downwardly toward the transverse center line of the car, the exit opening at the lower end of the member 24 normally being closed by the transverse dump door 21, which when closed forms a tight seal with the lower ede of the member 24,- It will be understoo that the slump doors 21 forming-portions ofthe transverse per members,

and dump doors associated central A swing inwardly toward eaclfotlier withflfe floor portions over the trucks for when moved into open position and outwardly away from each other when moved into closed position. The transverse dump doors 21 maybe operated by any usual oper-- That portion-of the ting mechanism 2 7 load which is not dumped to thesides of the car past the side door 16 will be dumped past the transverse dump doors 21 between the tracks andbetween the trucks,' the carjbk ing self-cleaning throughout due tofjthe' sloped arrangement of allof the floorpor-I tions.

As stated above, bymaking' the floor portions over thetrucks in the form of longitudinally extending A-shaped members 13, the capacity of the car is effectively in creased, and at the same time the self-cleaning feature maintained. I

It is my intention to cover all modifications of the invention fallingwithin the spirit and Scope of the following claims.

101m -1. A dump car having sides, ends and a floor, the floor portions over the trucks including members sloping downwardly and outwardly toward the sides ofthe car, the

floor intermediate the trucks. including hop.- per members having transversely arranged dump doors which swingf towardeach other and away from each other intoopened and closed positions, respectively.

2. A dump car having sides, ends and a floor, the floor portions over the trucks including membersisloping downwardly and outwardly toward the sides of the car, the

v floor intermediate the trucks including hop:

dumpingtheiloadito the sides of the car, said hopper members including transversely arranged dump doors which swing toward each other and away from each other into opened and closed positions, respectively,

whereby the remaining portion of the load maybe dumped "between the tracks and trucks. v I v I, 3. A dump car"having"sides, ends' and a floor, the [floor portions over the trucks ineluding members sloping downwardly and outwardly: toward the sides of the car, the.

floorintermediate the trucks including hopper members, dump doors associated with the floor portions overthe trucks for dumping theload to the sides of the car, said hopper members including transversely arranged dump doors which swing toward and away'from eachother into opened and closed positions, respectively, whereby the remainingportion of the load may be dumped between the trucks, and dooroperating mechanism whereby said dump 'doors may be operated. i

4 A dump car having sides, ends and a floor, the floor overthe trucks including A- shaped portions arranged to. discharge the load toward the sides ofthe car, the remaining portion of the floor comprising'hopper walls extending downwardly and toward each other, one'from the transverse center of t c and the ether from o e of s id A-shaped portions, I r
