MINE CAR 7 Filed Aug. 20, 1950 I'll .belts or bandswhich extend entirely Patented Nov. 1, 1932 WILBUR D. HOCKENSMITH, 31%., OF IRWIN, PENNSYLVANIA 7 time CAR Application filed August 20, 1930. 7 Serial No. 476,508.

This invention relates to mine cars and more particularly to improvements in the construction thereof. The standard mine car in existence at the present time comprises a floor, flaring side floors extending from the floor and side walls riveted to the side floors. The car is tied together and reinforced by around the car. The belts are relatively thick (usually one inch) in comparison with the thickness of the side walls (usually about onequarter of an inch). A mine car built with the belts around the outside has a limited capacity in relation to its overall width and length, that is the inside width is at least two and one-half inches less than the overall width. In mining where space in which to work is usually limited and the entries in the mine are of' relatively narrow width, it is 11ecessaryto provide a car having a maximum load capacity with a minimum height for easy loading and a minimum width to insure suflicient clearance between the sides of the car and the sides of the entry. The use in mining 2 of cars having a relatively small load capacity materially increases the cost of mining.

One object of this invention is to provide a mine car having an increased load capacity without increasing the overall dimensions thereof.

Another object of this invention is to provide a mine car having belts or bands on the inside of the side walls of the car.

A further object of this invention is to provide a mine car in which the end gate is fastened to a triangular plate pivoted to the outside of the car.

A still further object is to provide a mine car in which the reinforcing belts or bands are completely inside the side wall and the side floors of the car.

These and other objects, which are readily apparent to those skilled in this particular art, I attain by means of this invention, one 4 embodiment thereof being described in the following specification and illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of a mine car embodying this invention. Fig. 2 is a partial end View of said car having a portion thereof cut away to show the construction. Fig. 3 is an end view of this car.

Fig. 4 is a partial end View disclosing a modified form of construction; and

Fig. 5 is a partial View in section disclosing a modified form of construction.

In the drawing, 1 have illustrated'a mine car of the standard type in which a floor 1 is provided, which is composed of three planks extending lengthwise of the car. The floor is braced by T-shaped bars 2 which are placed between the planks. The T portion of the bar is countersunk in slots provided in the planks. The floor 1 is shown suspended from axles 1 which are enclosed inlishaped housings 5 having laterally extending flanges '6 thereon. Bolts 7, extending through the floor, secure the floor to the flanges ii of the housing. The axles 4 may be stationary within the housing 5 or they may turn with the wheels. In the latter case, the housing is provided with bearings (not shown) which support the axles. Wheels 8 are journalcd on the ends of the axle on each side of the car. Angle irons 9 extend the full length of the car on each side of the floor and form side sills for the car.. Plates 10, having oppositely disposed flanges 11 and 12 along the edges thereof, :form side floors for the car. The flange 11 is riveted to the angle iron 9 and plates 13 which form the side walls for the car are riveted to the flange 12. The side walls and side floors are reinforced and tied to the other parts of the car by reenforcing .members or belts 14, which extend entirely around the car. In my improved type of construction, I place the belts 14 on the inside of the side walls 13 and underneath the side floors 10. Openings 15are provided in the side floors 10 through which the belts ll are extended. The belts are riveted to the side walls and side floors and bolted to the floor 1, so that the planking may be readily changed. The belts are countersunk in the floor 1 to obtain sufficient clearance between the bottom of the car and the rail, for otherwise larger wheels would have tobe used to obtain a given clearance and, therefore, the

overall height would have to be increased to obtain a given capacity.

By placing the belts 1 L inside the side wall, I have increased the load capacity of the car without increasing the overall width thereof. This construction also permits the use of a different type of bailor gate lift than is commonly used, which materially reduces the overall width of the car. In building my car, I provide a gate 16 of the usual type for closing the end of the car, which is fastened along the sides thereof to triangular plates 17 (one of which is shown). The plate 17 is pivoted at 18 on the side 13 of the car. The plate 17 forms the bail or lift for the gate 16. The pivot 18 is reinforced by a plate 19 riveted to the inside of thecar. The placing of the belts inside the side walls leaves the outside of the wall relatively smooth and free from projections, making it possible to place the plate 17 very close to the side wall and by using a relatively thin plate for a bail instead of the ordinarily used relatively thick bar, the overall width of the car is materially reduced.

In Fig. 4, I have shown a modified construction of a mine carin which belts 20 are placed on the inside of the car adjacent the inside of walls 13 and the side floors 10 and underneath the floor 1. The side floors 10 are provided with openings 21 adjacent the side sills, through which the belts 20 extend. The belts in this modification extend entirely around the car and are countersunk in the floor 1. The end gate and the lifting .bail are exactly similar to those already described. It is readily apparent that by placing the bands orbelts inside the side walls of the car, the inside width is increased by double the thickness of the bands, while the overall width of the car remains the same. In the modified form, the load capacity is further increased when the belts are placed inside the side floors as Well as the side walls- My invention is also readily applicable to other types of mine cars such as an all steel car, wherein the belts or bands are in sec tions and do not extend entirely around the car. In Figure 5 I have partially shown a car having the belts in sections. In such cars the side sills are comparatively heavy and sufficient reinforcement for the car can be obtained by riveting the .belts directly to the side sills. In Figure 5, belts 30 are riveted to the inside of the side wall 31 and may be riveted to the inside or outside of the side floor 32 as in the other embodiments of my invention. The ends of the bands are riveted to, a side sill 33. Mine cars, when in use, bump against each other and are subjected to severe shock. For that reason it is desirable to have the floor of the car constructed of relatively thick planks, the ends of which protrude beyond the ends of the body portion and act as bumpers for the car. The

floor, and

body of the car is usually bolted directly to the floor boards and the shock of bumping is taken by the bolts. By countersinking the belts in the floor I am able to use a thicker plank floor than otherwise and obtain the advantage of the larger bumping area without encroaching upon the capacity of the car. Also the belts are madeto fit snugly in the grooves in the floor boards and the edge of the belts gives added area in addition to the body bolts for absorbing the shock of bumping encountered in usage.

While I have illustrated an end dump car having the. fioor suspended from the axle, it is readily understood that my invention can be applied to any type ofcar, such as cars having the floor above the axles, and cars of the rotary dump type. It is also readily apparent that certain omissions, additions and substitutions may be made in this applica-.

tion without departing from the spirit and scope of the appended claims.

What I claim as new and desire to secure by Letters Patent is:
