Abstract

670,909. Trussed brake beams. OAKLEY, J. L. D. (American Steel Foundries). Feb. 24, 1950, No. 4814/50. Class 103 (i). A trussed brake beam comprises channelshaped compression and brake head members, each having top and bottom walls and one of which is secured between the walls of the other, the beam also having a tension member inclined to the compression member to form a truss therewith and having its end secured by welding in a rearwardly-facing socket in the brake-head member to lock the compression and tension members together, the weld metal being located on the brake head member socket and fusing the brake head and tension members. As shown in Fig. 10, the tension member engages inclined surfaces 33, 34, 35 in the socket formed in the brake head member 28, and the rear web of the compression member 31 is formed with a slot 39 through which the rear wall 36 of the brake head and the end of the tension member 32 are welded at 41. In'the modification according to Fig. 26 the tension member 162 engages surfaces 157, 160 on the brake head 144, the weld metal 163 being deposited through a slot 158. The tension member 154 engages a lug 155 on the brake head. In a third arrangement, Fig. 33, the tension member 173 bears against surfaces 194, 203 in the brake head socket, and the weld metal is deposited through slots 183, 206 in the brake head 171 and compression member 172 respectively. The Specification also describes further embodiments.
