By forming the end-boxes integral 50 end of the truss-rod into the socket. with the main member of the beam, the con- I00 struction is greatly simplified and cheapened. Moreover the pressure of the nuts on the ends of the truss-rod is directly against the endsurfaces of the main member, which insures strength and stability.
The construction at the ends of the beam enables brake-shoe heads to be applied which are constructed to receive different, forms of brake-shoes.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is
1. In a trussed metallic brake-beam, the combination of a main member having integral boxes at each end each box comprising a socketwhich extends diagonallyfro m the front to the rear side of the box; said boxes provided withvertical flanges f, a truss-rod having end-portions which engage through said sockets and have nuts on their ends bearing against the end-surfaces of the boxes and brake-shoeheads fitted to the boxes, between said vertical flanges.
2. In a'trussed metallic brake-beam, the combination of a main member having inte gral boxes at each end each box comprising a socket which extends diagonally from the front to the rear side of the'box; a truss-rod having end-portions which engage through 1 said'sockets and have nuts ontheir ends bear ing against the end-surfaces of the boxes; 1
brake-shoe heads having base-flanges which fit against the front sides of the boxes; and
bolts extending through the boxes and having heads which take over the flanges of the brake-shoe heads.
3. In a trussed metallic brake-beam, the combination of a main member having stoplugs at the middle part; an angle truss-rod suitably connected at the ends with the said main member; aking-post or strut between the main member and truss-rod at the middle of the beam and mounted at one end on a stud projecting from the truss-rod and fitting against the front side of the main member at the other end and provided with lugs to stop against those of the said main member; and a bolt extending through the end of the strut and through the-said main member and having a nut on its end behindthe main member.
4. In a trussed metallic brake-beam, the combination of amain member having boxes 'at its ends; an angle truss-rod which is T- shaped in cross-section andhas rounded-ends fitting through the boxes of the main member and secured by nutsbearingagainst the ends of the main= member; ablock fitting the angle of the truss-rod and straddling the centand abutting the main member at the oppo- :site end; a bolt and nut eonnect-ingsaid strut with said main member; and suitable stops :tfo-limit the movement of t'he str ut.
