INVENTUR 122221 jBar/z w W ATTORNEY UNITE DAVID L. BARNES, OF CHICAGO, ASSIGNOR TO THE FOX SOLID PRESSED STEEL COMPANY, OF JOLIET, ILLINoI's.
BRAKE-BEAM FOR RAILWAY-CARS.
SPECIFICATION forming part of Letters Patent No. 512,497, dated January 9, 1894.
Application filed April 16, 1891. Serial No. 389.253-' (No model.)
To all whom it may concern.-
Be it known that I, DAVID L. BARNES, of Chicago, Cook county, State of Illinois, have invented a new and useful Improvement in Composite Brake-Beams for Cars, of which the following is a 'full, true, and exact description, reference being had to the accompanying drawings.
This invention relates to an improvement in metallic brake beams, or brake beams composed essentially of metal; and it consists of an arrangement of such beams whereby lightness and strength are combined, with, at the same time, a low cost in construction.
My invention will be readily understood from the accompanying drawings, in which Figure 1 represents a plan View; Fig. 2, an end elevation on the shoe side; Fig. 3, a section through Fig. 2 on the line a; w; and Fig. 4, a section through Fig. 2 on the line y y.
My brake beam consists essentially of two open boxes, by preference made of pressed steel bolted together and separated by intermediate blocks.
The top' and bottom members, A B, of my beam are substantially alike, and are generally of box shape, as clearly indicated in the drawings. They are separated at the middle bya box- 0, which may be of one or two pieces, as desired: The top and bottom members are riveted to the box O by rivets D, and the box 0 serves likewise to aid in carrying the brake lever fulcrum E, which may be of any suitable construction, and is preferably provided with wearing-plate F and bolt G, as shown.
The brake shoe II may be of any suitable form. It is'supported in the usual way at the ends of the brake beam, and the parts A and B are separated by similar boxes J at those ends, as shown,-the upper and lower members being secured to said boxes by rivets K.
The combination of the pressed steel parts A and B and of the boxes Oand J, which may be of cast metal, enables the formation of a very rigid beam, easy of repair and cheap in construction.
The brake shoes may be attached in any proper way. As shown, they are carried by the bolts L attached by nuts and washers M, as clearly shown in Fig. 8. The closing of the ends of the box shaped portions maybe omitted, although I prefer the construction shown.
. By the separation of the boxes I evidently increase the lightness of the beam without diminishing its rigidity against strain.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. The combination of the pressed steel boxes A B separated and attached together by box 0, substantially as described.
2. The combination of the pressed steel boxes A B separated and attached together by box 0 and by boxes J, substantially as described.
3. The combination in a brake beam of the parts A B having lips at the front and back, the said lips embracing the box 0 which'is riveted to.the parts A B, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
DAVID L. BARNES.
