IMPROVED OIL-TANK OAR,

TO ALL WHOM IT MAY CONCERN:

Be it known that we, George W. Ilgexeritz and Michael Schall, of York, in the county of York, and State of Pennsylvania, have invented a new and improved Mode of Constructing Oil-Tank Cars; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings maki.ng a part of this specification, in which—

Figure 1 is an elevation of one side of the improved .oil-tank .and car.

Figure 2 is a longitudinal section, taken in a vertical plane through the oil-tank and car-bed, with the trucks removed.

Figure 3 is a bottom view of the car-bed and its oil-tank,' with the trucks removed.

Figure 4 is a transverse section, taken through the tank and car-bed, in the vertical plane indicateciby red line y' y' in fig. 2.

Figure 5 is a section through the oil-tank, taken in the vertical plane indicated by red line y y in fig. 2.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to certain novel improvements on the construction of tanks and cars for the purpose of safely and economically transporting oil and other liquids from one point to another by railroad.

Our invention is designed more particularly for’the transportation of coal-oil upon railroads, but it is equally useful for the transportation of other liquids.

It consists in so constructing, bracing, and arranging a ear-bed, for receiving a cylindrical oil-reservoir, that such reservoir or tank can be arranged so low that the weight of the liquid in it will be brought in close proximity to the road, instead of being above a car-bed, which is considerably elevated from the roadway, thereby causing the car to cling closer to the track, and greatly lessening the danger of running off, as will be hereinafter described.

It also consists in so constructing the tank or reservoir for containing the. oil or. other liquid that it shall possess great strength, and allow of the ready withdrawal of the oil, and the carrying with it of all sediment, for which purpose the bottom of the tank is depressed or bellied both laterally and longitudinally, so that all the liquid and foreign substances in the tank can be drawn off, which could not be done with a straightbottom tank.

To enable others skilled in the art to understand our invention, we will describe its construction and operation.

In the accompanying drawings, fig. 1, we have represented our improved car-bed and tank, mounted upon two trucks, K L, which may be constructed in any suitable well-known manner.

The car-bed consists of four or more longitudinal sills, G G G G, which may be made of wood or metal, and arranged in planes parallel to each other, at proper distances apart. These sills are united firmly at their extremities to transverse pull-timbers D D, and braced and tied together at intermediate points between said timbers D D by means of the bolsters E E and transverse bars D D. The bolsters E may be constructed of wood or metal, and if made of the latter they would consist of bars or plates, suitably stayed and strengthened by diagonal braces bolted between the two plates forming each bolster. The bolsters are bolted upon the bottoms of the longitudinal sills, and the two’ intermediate ones are placed at such a distance apart as to allow the oiltank B to come between them, and rest upon chairs g g. These chairs are of such form aS to receive snugly upon them, and afford firm wide seats for the cylindrical portions of the ends of the tank B, and they are bolted down upon the upper sides of the bolsters E, as shown in figs. 2 and 4. '

The transverse tie-bars D D, which are bolted to the bottoms’of the sills G, between the bolsters E, servo as supports for the depressed or bellied portion of the tank, on both sides of the centre thereof.

At the extremities of the tank B, and framed in between the two intermediate sills G G, are transverse pieces J J, which form seed abutments and stays for the tank, to assist in preventing longitudinal thrust and displacement, and directly beneath these stays are inclined braces, C C, shown in figs. 2 and 3, which incline

By means of the straps a the tank is held down firmly‘in place upon its bed. The ends of these straps a are passed down through the bolsters E E and cross-ties D D, and provided with screws upon their ends for receiving nuts, by which to tighten the straps and keep them tight.
