By the use of'my invention it is possible for the makers of brake beams and their customers, such railroads who wish to carry repair parts in their repair shops, to dispense with right a. l left hand struts,

In placing the strut in position on the no compression member, the tongue" D is sprung out sutlic ently far toenable the easy introduction of the compression member. into shaped seats,

the space provided therefor in the end of the strut, and with the strut in its int nded position the workman preferably, by blows of a hammer, drives't-he legs or flanges of the compression inei ber into the wedgeand at the same-time forces the tongue D down into position, so that the key a may be passed through the opening therein and 111 the walls" E.
