fizz/67575;: Jamal/92 3 UNITED STATES DAVID HINDAI-IL, OF CHICAGO, ILLENOI-S,

COMPANY, OF CHICAGO, ILLINO PATENT OFFICE;

CONVERTIBLE BUM]? CAR.

Application filed March 29,

To all whom it may concern Be it known that 1, DAVID Hrnnenn, a citizen of the United States. residing? at Chicag'o in the county of Cook and State of Illinois have invented certain new and useful Improvements in Convert ble Dump Cars, of which the following is a specification.

This invention relates to a new and improved convertible dump car and more par ticularly to an end construction tor such cars.

As is well known in the art. various terms of convertible cars are in use. the end portions of which over the trucks are provided with relatively flat fixed floors while the portion between the trucks is provided with varying types oi? dump doors and hopper constructions. In certain positions of the center floor construction, a flat tloor. substantially continuous with the flat iioor ends. is provided. In. other positions oi? the tloor elements. varying types of hoppers are formed in the center portion 0'! the car.

\Vith cars of this general character, when the car is used with the substanti 7. flat floor throughout, it is ordinarily oesirahlc to have the greatest possible l'loor area and consequently the end of the car should he located at the extreme end of the car frame. On the other hand, when the central portion of the car is so utilized as to form hoppers, it is often desirable that an auxiliary end he formed, within the car at the point of junction between the central hopper portion and the fiat floor ends of the car. Such a location oi? the auxiliary ends is desirable in order that the entire contents of the car may be discharged through the hoppers and further where heavy material is handled, the weight carrying capacity of the car will often be fully utilized by a load intermediate the inwardly spaced ends.

Certain prior forms of cars have been designed having supplemental end portions which may be swung into place at the ends of the hopper portion and other terms of cars have been constructed in which the car ends are movable bodily from the extreme end of the car to the inner end of the flat floor over the trucks.

W'here supplemental swinging or other wise movable ends are provided, the car construction is complicated. and con .erable Specification of Letters Patent.

additional weight is required. Where the car end moved hodilv the car structure is considerably weakened since the conned tions between the ends and sides when detachable in character are not as ellicient as a permanent structure and further since when the ends are moved inwardly the sides are not adequately cross-connected at the extreme ends oil. the car.

lit is an object oil? the present invention to provide a car construction whereby a removable end may be placed at a desired intermediate portion of the car. such end comprising: elements oi? the normal end construe tion, the normal end construction being so designed as to permit removal of these ele ments without strinirturally weakening the permanent end.

It is a further ohiect to provide a construction of this character in which the movable eleiinents are of such size as to be }"lttlll V handled whereby the change in eli'ed tive end location may be accon'lplished rapidly and with a small GXiJt-Hldll/UTG of labor.

(.lther and Further objects will proceed as the desorption. proceeds.

Broadly my invention comprises an end cou tnotion in which the end training ele n'ients are permanently seemed in place and in which the end wall tormino; elements or a portion thereof are readily removable from association with the framing elements.

I have illustrated a preferred embodiment 01"? my invention in the accompanying drawings, in which- Figure l is a side elevation showing; one end of a car constructed according to the present invention;

Figure 2 is an end view ol the car shown in Figure 1; and

Figure 3 is a fragmentary section illustrating the construction.

The car shown in the drawings has 'llat floor portions 5 extending over the trucks at the ends of the car and has a hopper portion 6 extending intermediate the trucks. The side of the car consists of truss ilrame T and wall forming elements 8. which latter are permanently secured to the frame. These portions of t car may he any usual construction and the detail of the car shown forms no part of the present invention.

As shown in Figure :2, the end of the car consists of an upper rail 9 which permanently connects the corner verticals 10 and which is further connected to the bottom cross member 11. by the vertical elements 12 and 13. The elements 1.3 are connected to the top rail by means of plates 141; which aid in stifli'ening the end frame construction. The lower wall member 15 is permanently secured to the frame.

The retaining member 16, as shown in Figure 3, is pivoted at 17 to the inside of the car side adjacent the rear face of the fixed end wall member l5. 'lhc element 1.6 is an angle bar having a flange 18 engaggging the movable wall elements 11/ and urging them against the various vertical members of the end frame. The flange 1.8 is provided at its upper end with the hook portion 20 which engages the upper surface of the upp r movable wall member andprevents VQLMC l displacement of said members. 'llhe dog 21, is pivoted at 22 to the inside of the car side and the cam surface 23 of the dos; engages the inner edge of the retaining member 16 and maintains that member against the removable wall members 19.

As shown in Figure 1, a verti 'ally extending U-member 2 is s cured upon the inside of each car side at the points of junction between the hopper portion and the fiat end portions of the car floor. The distance bctween the legs of the ll is of a width adapted to receive the removable wall members 19. ln the form shown, these ren'iovable wall members consist of wooden planks. 7

When it is desired to remove the wall members 19 from the end of the car, the dons 21. are swung so as to permit the retai nine mem- Uers 1.6 to be swung about their pivots away from the end. The members 1.9 then may be readily lifted from place and are inserted in the guideways formed by the ll-members 24. They are retained in place by gravity in these guideways.

Since each member 1.9 is comparatively small, its weight is not ermessive and the movement of the end may be accomplished without great labor. It will. be noted that when the members 19 are in place .in the U- guides 241-, the car side frame construction is effectively supported and connected by the permanent end frame elements which remain in place. There is thus no weakening of the car. The lower end element 15 which rcmains in place permanently serves to catch any material which may flow over the inner end in loading and to prevent such material from falling out of the car end. Due to the absence of any solid end above this lined member, however, such material maybe readily shoveled from the car.

The particular embodiment shown to he understood to be illustrative only and it is my intention to cover all. modifications coming within the spirit and scope of the appended claims.

li claim:

l. In a railway car, a sectional end, certain of said sections being removable, and means located at points intermediate the car ends adapted to retain said sections in place at such points.

2. ln a railway car, permanent end frame members, end wall sections removably asso ciated with said frame, and means located at points intermediate the car ends adapted to u said sections in place at such points. 0.

7. In a railway car, permanent sides, permanent end frames connecting the sides, removable walls located against the inner side of the end frames, means adapted to maintain said walls in place against the frames, said means being adjustable to permit re moval of the walls, and additional means adapted to support the walls at points intermediate the car ends.

8. In a railway car, permanent sides. permanent end frames connecting the sides, removable walls located against the inner side of the end frames, guides adapted to maintain the Walls in place against the frame, said guides being adjustable to permit removal of the walls, and Ll-shapcd. guides adapted to support the walls at points intermediate the car ends.
