14 Claims. (01. 188205) My invention is directed to a novel form of steel casting designed for use as a railway car underframe reinforcing member, a carrier iron and a fulcrum means for brakes associated with said car. ure 3 is an end elevation; 6'

ture to compensate for the additional stresses In Figures 4 and 5 I have shown a typical apinvolved. plication of my novel form of casting to the With these and various other objects in view, underframe of a car body. It will be apparent the invention may consist of certain novel feathat my novel casting is secured to the center DU tures of construction and operation as will be sills at the normal position of the carrier iron, more fully described and particularly pointed out between the car end and the bolster IS. The in the specification, drawing and claims apcasting l is secured to the under surface of the pended hereto. spaced center sills I4, M as by means of the In the drawing which illustrates an embodirivets 45, 45, the depressed central portion of its ment of the device: upper surface forming a seat I8 for the yoke 55 normally associated with the draft gear, said casting having adjacent one end thereof the novel form of brake lever fulcrum 10 as above described. The brake lever 24 is received in the slot 22 as most clearly seen in Figure 4 and secured therein at a point intermediate its ends by the pin 30.

Other portions of the brake rigging may normally be connected to the opposite ends of the brake lever 24 as at 48 and as shown for example in the above described Hedgcock application Serial No. 72,894.

It will thus be seen that in my novel form of composite casting I have provided at a critical point a substantial reinforcement for the spaced center sills of the car body while, at the same time, furnishing an adequate carrier iron and a satisfactory form of fulcrum connection for brakes normally associated with the truck upon which the car body is supported.

It is to be understood that I do not wish to be limited by the exact embodiment of the device shown, which is merely by way of illustration and not limitation, as various and other forms of the device will of course be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.

I claim:
