ATTORNEYS United States Patent 3,228,351 TILTING DUMP CAR REINFORCED END WALL CONSTRUCTION Henry Fort Flowers, 3023 Del Monte Drive, Houston 19, Tex. Filed Feb. 27, 1963, Ser. No. 261,454 10 Claims. (Cl. 105-272) The following specification relates to reinforced end construction of side dump cars of the type designed primarily for large scale movement of soil, ores, coal and like material.

Cars for these purposes must be exceptionally rugged to withstand loading from a travelling bucket, conveyor or the like in which material varying from fine particles to ponderous boulders are dropped into the cars. Frequently such heavy material, especially boulders, will strike the ends of the cars and be lost or rebound into the car. It is important under such circumstances to protect the end walls and pivoted sides of the car from the impact of heavy material.

One of the objects in the invention is to strengthen the end of the car body by bracing it in different directions.

A further object of the invention is to form the posts which brace the end walls in rigid box sections which can be welded directly to the end walls. They thus form reinforcements over the entire height of the end walls.

An important advantage of the invention is to brace such reinforcing posts not only over the vertical extent of the end walls, but also directly to the car bottom and for an extended distance below, so that the leverage is substantially increased.

A further object of the invention is to provide that the lower ends of such reinforcing posts will be braced from the conventional flaring skirts of the car bottom.

A still further object of the invention is to provide sloping, deflecting plates across the end walls of the car suitably braced against the posts as designed.

As illustrating the preferred form the invention has been shown on the accompanying drawings in which:

FIGURE 1 is the end elevation of a side dump car embodying the improvements;

FIGURE 2 is an enlarged fragmentary view and FIGURE 3 is an enlarged fragmentary side elevation of the same.

Briefly described, the invention consists in providing diagonal posts against the end walls of the side dump car. These posts are of novel construction made from standard U-shaped channel bars of light metal. These posts extend the full height of the end walls and below the car bottom where they are braced to the bottom or floor of the car body and also by resting at a lower point against both the flaring skirt of the car body and an associated gusset. The posts supply adequate reinforcement for an inwardly sloping plate across the upper edge of the end wall.

The side dump car is of the type having a tiltable body 4 with down folding doors, or tiltable side walls, for discharge. The car has truck frames 5 mounted on wheels 6. The underframe of the car has the usual construction. Each end of the underframe carries a coupler 8 and the underframe is provided with means for controlling the tilting of the body together with the down folding of the side doors, not shown, by means of a control lever 9. This control lever will provide for selective tilting for the car body and simultaneous pivoting of one side for discharge.

A shield 10 is provided over the coupler 8 and associated parts.

The tiltable body 4 has transverse beams 12.

The transverse beams 12 support a floor bottom or plate 13. This bottom extends to the side with down wardly and outwardly flaring skirts 14, 14.

Each skirt 14 is connected to each end of the floor plate 13 by means of a triangular gusset 15, also of light, rigid material. It is to be understood that the parts are continuously welded at their meeting edges.

The end wall 16 of the car is made of suitable metal, and in view of the reinforcing this may be relatively thin gauge.

Side doors

17, 17 are hinged at the bottom of the car body for outward tilting selectively in a well known manner.

The upper edges of the end walls 16 are provided with inwardly inclined slope plates 18. These are designed to reinforce the upper edges of the end walls and also to deflect inward any material which falls outside of the vertical plane of the end wall.

Each slope plate has an inwardly inclining backing plate 19. The backing plate welded to the outer edge of the slope plate 18 is also welded or otherwise attached at a suitable point below the top edge of the end wall.

A brace 20 extends from each end of the backing plate 19 downwardly parallel to the outer edge of the end wall, for attachment and support upon reinforcing posts.

A grab handle bar 21 runs horizontally between the upper ends of the braces 20 for convenience of the train men.

Two channel bars 22, 23 Welded edge to edge, form a hollow box post. This post extends diagonally from the backing plate 19 to the lower side edges of the bottom 13.

At the top the posts are braced against the backing plate 19 by means of an anchor plate 24.

At the level of the car bottom 13, the outer side of the posts carry reinforcing straps 25 which add to the rigidity and strength of the posts.

The lower ends of the

channel bars

22, 23 are closed by a cross plate 26.

Braces 20 support the thin end wall 16 far enough from the inner face of the down folding side door to prevent chunks of material from blocking the door from closing and sealing the opening between end wall and door; thus providing a thin door jamb.

The unsupported area of the end wall is reduced by a U-shaped horizontal member 30 with its edges welded to the end wall 16 and its ends welded to posts 23.

The lower edges of the skirts 14 have welded angle bars which form feet 27 projecting beyond the .ends of the skirts. The projecting ends of the feet 27 are rests for the cross plates 26 of the posts. (See FIGURES l and 2.) Cross plates 26 are attached by suitable means, such as Welding, to the feet 27.

A tie bar 28 attached to the upper face of the member 22 runs through the gusset 15 and is attached by any suitable means, such as welding, to the car bottom or floor at this point.

A similiar tie bar 29 is attached to and supports the lower side surface of the member 23. The tie bar is suitably connected to the floor plate. In this manner the inclined post is braced to the floor plate at an intermediate point.

With the construction described above, an end construction for dump cars is provided which is greatly reinforced. By providing inclined end posts attached to the ends of the car and extended to points of anchorage below the car bottom, the car end is materially reinforced. The car end is also braced along the line parallel to the side edges of the end wall. Means are provided to hold the post both at the bottom of the skirt and along the end of the skirt and the end of the floor plate.

The posts and braces form additional support at the top of the end wall. They serve to support a deflecting plate which is both a source of added strength and a control for material which might otherwise be lost.

This construction is capable of fabrication with a minimum of skilled labor from light Weight material, thus increasing the economy of the product.

The invention has been shown in the preferred form but may be changed in minor details of material and proportions within the scope of the appended claims.

What I claim is:

1. In a side dump car body having a bottom with flaring side skirts, end walls and pivoted sides, the combination of inclined posts attached to the end walls and extending from their upper edges into supporting engagement with the side skirts below the car body bottom and tie bars connecting opposite sides of the posts to the lower surface of the car body bottom.

2. A side dump car body having a bottom with flaring side skirts, end walls and pivoted sides, gussets connecting the edges of the skirts with the ends of the bottom, and inclined posts attached to the gussets substantially parallel to said skirts and to the end walls for their full height.

3. A side dump car body having a bottom with flaring side skirts, end walls and pivoted sides, gussets connecting the edges of the skirts with the ends of the bottom, inclined posts attached to the gussets substantially parallel to said skirts and to the end walls for their full height and tie bars connecting opposite sides of the posts to the lower surface of the car bottom inwardly of said gussets.

4. A side dump car body having a bottom with side skirts flaring downwardly and outwardly therefrom, end walls and pivoted sides, a ledge on the lower end of each skirt extending inwardly therefrom, and posts attached to each of said end walls and diverging downwardly and outwardly therefrom to below said bottom into supporting engagement with said ledges, whereby said posts form a brace between said end walls and said skirts.
