COMBINED FREIGHT AND DUMP CAR.

SPECIFICATION forming part of Letters Patent No. 750,670, dated January 26,1904. Application filed February 9, 1903. Serial No. 142,453. (No model.)

To (all whont it may concern:

Be it known that I, ARTHUR LIPSCHUTZ, of the city of St. Louis, State of Missouri, have invented a certain new, useful, and Improved 5 Combined Freight and Dump Car, of which the following is a specification.

My invention relates to railroad-cars, and has special reference to freight-cars that may be employed as dump-cars for carrying and I distributing material, such as sand, gravel,

coal, coke, and the like.

The object of my invention is provide a car that may be used as a freight-car or as a dumpcar and which shall be free from the objec- I tionable features that are present in all other combination-cars.

The principal object of the invention is to provide a self-cleaning dump-car upon the opening of the doors of which the whole contents of the car will be discharged, shoveling being avoided.

Another particular object of the invention is to provide a dump-car that shall have. a level flat bottom to accommodate any sort of 5 freight, being unobstructed by ridges, depressions, or hoppers.

Another special object of the invention is to provide a dumping-car having a level floor and which shall be of uniform cross-section 3 throughout the extent of the underframe to the end that the capacity of the car shall be as great in the portions over the trucks as at the center of the car.

Another object of the invention is to provide a dump-car the floor of which shall be substantially wholly composed-of large dropdoors, and, furthermore, to provide a combination-car that may take the form of a flatcar, a coal-car, a coke-car, or a box-car with- 4 out change in its underframe or floor.

The general object of the invention is to provide a combined freight and dump car of simple construction,capable of being easily repaired if damaged, and which may be built at less cost than other cars adapted for the general purposes mentioned.

A further object of the invention is to provide a combination-car of such construction as to permit of the employment of any style or type of trucks and which shall not require special constructions or applications of brake mechanisms.

My invention consists generally in a combined freight and dump car the floor of which from end sill to end sill is substantially wholly 5'5 composed of drop-doors, which being'opened permit the discharge of the whole load of the car.

My invention further consists in a car of the class described, the underframe of Which comprises suitable body-bolsters or cross-girders, in combination with side girders, a pinrality of cross-beams extending between said side girders, and a plurality of doors or traps filling the openings between the beams and 6 5 girders and constituting the floor of the car.

My invention specifically consists in a car having an underframe composed of side sills or girders in combination with cross-beams extending between said girders, an articulated 7 center sill extending from end to end of the car, and a plurality of doors hinged upon said center sill and constituting the floor of the car.

My invention consists, further and specifically, in a-car having its underframe composed of rectangularly-arranged longitudinal and cross-girders, provided with floor plates or flanges and doors closing upward beneath said flanges, making tight joints therewith and having their surfaces in the plane of the tops of said flanges, and my invention consists, further, in various details of construction and in combination of parts, all as hereinafter described, and particularly pointed out in'the claims. 8 5

The invention will be more readily understood by reference to the accompanying drawings, forming a part of this specification, and in which Figure 1 is a plan View of substantially one- 9 half of a combined freight and dump car embodying my invention. Fig. 2 is a side elevation thereof. Fig. 3 is'a vertical longitudinal section substantially on the line 3 of Fig. 1. Fig. 4 is an enlarged end view of the ear. Fig. 5 is a similarly-enlarged cross-section substantiallyon the line 5 of Figs. 1, 2, and 3. Fig. 6 is a similar section on the line 6 of Figs. 1 and 2. Fig. 7 is an enlarged detail section on the line 7 of Fig. 1, and Fig. Sis a similar detail showing the construction in wood. 7 v

The advantages that are sought in cars of the class mentioned are substantially these: a perfectly level floorthat is, a floor without obstructions or depressions; vertical sides and ends that may be reduced orincreased in height, according to the use to which the car is to be put; a car-body of the same length as the underframe, whereby loss of load capacity is avoided, as compared with those cars in which the car-body is located between the ends of the underframe, starting at a considerable distance from said ends; drop-doors, by which the entire load of the car can be dumped without shoveling; doors of great size that will permit the passage of large rocks or chunks of ore or coal; few convertible parts, none, if possible, aside from the doors which constitute the floor; adaptability for use as flat, coal, coke, or boX car without reference to the character of the car-floor; simple and strong floor construction, having drop parts which at all times normally enter into the floor structure-that is, parts which are at no time extra or superfluous members, their functions being constant without reference to the character of the load, and, finally, great simplicity and economy of construction.

While other combination-ears may and have possessed one or more of the features and functions above enumerated, each contains objectionable features, such as elevated or inclined ends, floor-ridges, or a reduced body or permanent level floor parts, or convertible tilting floor parts, all of which either reduce the load capacity of the car or restrict the load to certain materials, reducing the earning capacity of the car as a unit or largely increasing the cost of constructing and maintaining the car. The ordinary combination freight and dump cars are also objectionable by reason of their great-weight, increasing the dead-weight to be hauled.

I conceive that the greatest number of desirable features and advantages attainable in a single car may be secured through simplification of car construction rather than by the addition of unique unusual structures or convertible movable members. My invention proceeds upon this conception, and the gist of the invention resides in the combination of side girders suitably supported upon the trucks and with a plurality of short cross-beams constituting the underframe of the car. The floor of this'car is composed of a large number of drop or trap doors or members, preferably normally in a horizontal plane, though, if desired, they may be inclined in either direction from the center or axial line of the underframe.

Vhile my invention is not limited thereto, I prefer the embodiment and construction illustrated in the drawings because of its simplicity, lightness, and cheapness. Again, while herein illustrated as an all-steel car my invention is equally well adapted for construction in wood. The main carrying members of the car are the side girders or sills. These are preferably the side plates or girders 2 2, which form parts of the underframe, and the sides of the car-body, obviously I-beams or channels or pressed shapes, may be substituted and, in fact, are used when a simple fiat-car is required. These side girders 2 2 are joined by a number of cross beams or sills 3 3, which have difi'erent forms at the center of the car, over the trucks, and at the ends. The crossbeams directly over the trucks serve as bolsters and are heavier than the cross-beams at the ends and middle of the car. The center or middle cross-beams are simple I-beams, having plates at their ends, by. which they are secured to the gusset-plates 4, depending from the sides 2, and strengthened by the upright bars or stakes 5. The cross-beams 3' over the trucks constitute the body-bolsters of the car and are constructed accordingly. Their detailed construction being unimportant to this invention need not be specifically defined.- The end cross-beams 3 are preferably built of angled plates heavily trussed and serving as the bufier or end sills of the underframe. It will be noted that any load placed upon the center cross-beams or the end cross-beams will be transmitted to the bolster cross-beams by the side sills, girders, or plates.

ous or spliced center sill I use an articulated sill 6, composed of light sections of sills 7 of small cross-section, arranged between the several cross beams 3 and having their ends abutted against and secured upon TGSPQCEiXG cross-beams. Such is the construction of the center sill betweenthe bolsters. Beyond the bolstersthat is, between the bolsters and the end sillsthe center sill is divided. to form casings for the draft-riggings. The construction of these ends of the center sill or girder is indicated in Figs. 2, 3, and 6, wherein itwill be seen that I prefer to make each end in the form of a short box-girder 7, containing the draft-rigging 8 and securely fastened between the end sill and the body-bolster'beamB'.

9 represents the top or cover plate of the end box-girder portion'of the center sill and this is preferably continued throughout the length of the car, forming, with the portion or narrow plate 9, a continuous-plate chord upon the top of the center sill. The crossplates l0 10 upon the tops of the cross-beams have their surfaces in the same plane with the plates 9 9, and all of these plates extend over or overhang the underlying beams, sills, or girders, whereon they are secured. Their edges therefore constitute stops for the floordoors of the car. The horizontal flanges of the angle-bars 11 constitute equivalent stops for the doors upon the sides of the car.

Because the cross sills or beams are very short they may be of light weight and small cross-section and yet sustain a heavy load between the sides of the car. For the same reason the cross-beams may be few in number, and hence it is possible to provide very large openings between the longitudinal and transverse girders or sills which make up the underframe.

The arrangem ent of the parts is symmetrical throughout thelength of the car and the openings are of-substantially the same size throughout, the only exceptions being the end dooropenings, which are somewhat narrower because of the greater width of the box-girder ends of the articulated center sill. A single door 12 is provided for each opening. This door is a fiat plate that is strengthened by angled or flanged bars 12 at its edges. At the outer edge of the door the angle-bar may be flush with the edge of the door-plate, but upon the other edges of the plate the angle-bars project far enough to close the cracks between the edges of the plate and the adjacent floorplates 9 10. As illustrated, the door closes tightly upward against the under surfaces of the overhanging floor-plates 9 10, and the side flanges 11, making a tight level floor for the car. The doors may be hinged either to the side sills or to the center sills, (I prefer the latter) and, as shown, the center-sill sections 7 and the doors or, if desired, the cross-- beams and the doors are provided with hinged lugs 12", secured by suitable hinged bolts or pins 13. The free ends of the doors are supported by chains 1 1, secured upon the winding-shafts 15, or by any other suitable means, as by latches. Stop-chains may be applied to all the doors, if desired, to limit their fall; but as the doors are usually of less width than the distance between the center sill and the railroad-track I prefer to dispense with stopchains upon the center or middle doors of the car and use the same only upon the doors which are above the trucks. In these places the stop-chains prevent the doors from striking upon the wheels and are therefore useful.

It will be observed that as the end doors four over each truckhave a limited fall plenty of space is left beneath them for the draft-rigging and for the air-brake and handbrake mec'hanisms, which may occupy their usual positions. The connecting-rod16 of the brake mechanism. is preferably arranged directly beneath the center sill, so that it does not interfere with the fall of the middle doors of the car.

The coal-car or gondola shown in the drawings has its sides composed of the side girders 2. Its ends 17 are preferably pivoted and provided with looks, as shown in Fig. 4, in order that the same may be thrown down to permit the carrying of long beams or poles that extend from one car to another. These end doors preferably have nothing to do with the dumping of the load. The upper edges of the car-body sides and ends are preferably strengthened by the usual angles, and it is obvious that the sides and ends of the car may be extended by any desired superstructure to convert the car into a coke-car or a box-car.

In constructing my car of wood the foregoing lines are preserved, and the doors, whether of wood or metal, make tight joints with the fixed portions of the car-floor, as indicated in Fig. 8. I prefer in making the Wooden car to notch the center sill and cross girder-s or beams, thereby gaining the advantage of a substantially continuous center sill. The essential feature to be retained in all cases is the light underframe composed of girders or sills that have narrow tops and which are separated by large distances, whereby upon the dropping of the doors the whole contents of the car will be discharged. The small quantities of material that will finally lodge upon the narrow tops of the center and cross sills are negligible in estimating the efliciency of the car. It will be obvious that a continuous metal center sill may be treated in a similar manner or may be placed beneath. the crossbeams.

I desire also that my invention shall includ the construction in which the center sill is placed on top of the beams,which extend from side to side of the car. In this case I should employ a V-shaped sill, though regarding its use asgenerally objectionable.

tions of my invention will readily suggest themselves to one skilled in the art, I do not confine the invention to the specific constructions herein shown and described.
