June 10, 1930. A. w. ALBRECHT CAST METAL CAR BODY Filed May 3; 1929 a n a J 4% m 7i i mrk E Ev C E Patented June 10, 1930 UTE!) STATES ALBERT W. ALBRECHT, F UNIVERSITY CITY, MISSOURI GASTJVIETAL CAR BODY Application filed May 3,

This invention relates to a cast-metal car body and an object isto provide a car body comprising a unitary casting so that the car body may be made of cast steel or its equivalent so as to dispense with the necessity of using rivets or bolts for fasteners, while at the same time the weight is not substantially increased, but greater strength and durability is obtained.

Another object of the invention is to provide a car body comprising a cast unitary floor provided with integral longitudinal and transverse reinforcing ribs and flanges and with means at the ends for supporting the coupling devices.

Other objects will appear from the following description, reference being made to the accompanying drawing in which Fig. 1 is a top plan view of my improved car body.

Fig. 2 is an under side plan view of my improved car body.

Fig. 8 is a side elevation.

As shown in the drawing my improved car body is in the form of a unitary casting comprising a floor wall 1 having a smooth upper surface and of less thickness than the usual floors of flat cars of the type shown. The floor 1 is a unitary casting ex 30 tending the full length and width of the an.

The upper surface oi": the floor 1 is unobstructed and smooth from end to end and from edge to edge.

Along each longitudinal side edge of the car body a depending reinforcing flange 2 is formed, the same being an integral part of the casting of which the car body is made. This flange 2 is relatively thin and comprises substantially less metal than the side supporting members of the usual car bodies. For, by making the car body of a unitary structure a very considerable saving of material is obtained.

Along the under side 01 the car body and spaced equidistant from the side edges thereof a pair of spaced longitudinal depending ribs or flanges 3 are formed. These flanges 8 strengthen the intermediate portion of the car body longitudinally and they displace the usual reinforcements and supporting ends of the flanges 8 and 2.

beams comprised in flat cars of ordinary construction having wood floors. The ends of these flanges 3 terminate at formations pro vided for the connecting pins for attaching the car bodies to the supporting truck struc ture. The formations shown comprise depending bosses -1l having holes 5 therethrough adapted to receive the bolts or pins for connesting the car body with the supporting trucks. From the outer side of each of the bosses d a pair of parallel depending flanges 6 extend to the adjacent end of the car body and it is between these flanges 6 that appropriate coupling devices are to be mounted so that the bosses a and the longitudinal ribs or flanges 3 will resist and withstand the loi'igitudinal strains to which a car body is subjected. These flanges 6 extend to the adjacent ends of the car body. Further, -lfrom each side of each of the bosses at a pair of depending flanges 7 extend to integral union with the depending side flanges 2.

From the corners oi the bosses 4. between the flanges 6 and the flanges 7 :1 depending rib or flange 8 extends to the end corners of the car body so that the ends of the car body beyond the flanges 7 are strengthened and reintorccd and this strengthening and reinforcement increased by a depending transverse flange 5) along each end of the car body extending from integral union with the ends oi? the flanges (5 to integral. union with the Thus no ordinary strains to which the car body is subjected can bend or distort the ends of the car body even though the coupling devices are made to exert very great lateral or torsional strains. Corner abutment bumpers 10 are formed at each corner of the car body on the transverse depending flanges 9.

The intermediate portion of the car body is transversely strengthened and supported by depending flanges 11 extending transversely across the car body to integral union with the side flanges 2. Thcseflanges 11 cross the spaces between the flanges 2 and 3 and also cross the spaces between the flanges 3, as will readily be understood by reference to Fig. 2.

In the embodiment shown my improved car body is formed with integral stake sockets 12 which are formed in connection with the side flanges 2 and which extend laterally therefrom. These stake sockets are oposite the ends of the flanges 11 so that there is sufficient bracing and strengthening thereof to resist any of the strains within the capacity of the car. The sockets 12 do not extend above the upper surface of the floor 1. 0n the contrary, the upper ends of the sockets 12 are approximately even with the upper surface of the floor 1, so that said sockets do not constitute any obstruction along either side of the floor.

At the ends of the spaces between the flanges 6 appropriate openings 13 are provided to receive the proper parts of the conpling devices.

From the foregoing it must be clear that my invention is a car body of highly simplified and of very strong and durable construction. Being made in a unitary structure and strengthened and reinforced substantially in the manner described, this car body is capable of withstanding all strains to which any car should be subjected.

I am aware that the construction may be varied within equivalent limits without departure from the nature and principle of the invention. 1
