BRAKE-BEAM.

Specification of Letters Patent.

Application filed July 13, 1910. Serial No. 571,764.

' To all whom it may concern:

a citizen of the United States, residing at Franklin, inthe county of Venango and Be itknown that I, Bnonnmon HASKELL,

State of Pennsylvania, have invented certain new and useful Improvements in Brake- Beams, of which the following is a specification. k

The present invention relates to brake beams of the metallic truss type and has for its objects, to provide. a strong and rigid structure which at thesame time is of very few parts, inexpensive and easy of manufacture, and whichwill permit the removal or renewal of the brake heads without disturbing the connected or rigid relation of the compression or tension members and strut. Y

The matter of novelty will be better un-' derstood from the following detailed description taken' 'in connection with the accompanying drawings, and the distinctive features will thereafter be pointed out in the appended claims.

Referring to the drawings, in which similar reference characters denote the same parts in the several figures: Figure 1, isa front elevation of a brake beam constructed in accordance with my invention; Fig. 2, is

an enlarged and longitudinal sectional view of one end of the brake beam shown in Fig. 1; Fig. 3, is a section on line IIIIII of Fig. 2; Fig. 4, is a similar view as Fig. 2, showing the compression member as being square in section; Fig. 5., is a section on line VV of Fig. 4:; Fig. 6, is a similar view as.

improved construction now to be described.

The compression member may be formed of a plate bent or rolled into a U section as shown at 1, in Figs. 1, 2, and 3, or it may be a solid bar, round, or square in section, as shown at 5 in Figs. 4 and 5, or channel in section, as indicated by '7, in Figs. 6 and 7 the particular cross section of said member not being material in the broader aspects of the invention.

The tension member 2 whilelpreferablv a rod circular in cross section asshown. may be of any suitable and modified form. In case a solid bar 5, is employed as the compression member, the ends thereof are recessed as shown at 6 in Fig. 4- In the practlce of my invention, the ends of the tension members 2, are provided with threads 9, whlch engage a nut 10 preferably of the shape shown and which is adapted to loosely fit within and abut against the end of the compression member, and while I prefer and have shown the abutting surface of. the nut 10, and compression member, normal to the tension rod 2, this is'not essentialto the invention, as this angle may be varied if so desired without departing from the invention. The brake head 3, is slipped over the end of the compression member, nut 10, and end of the tension member 2, and after these members are properly adjusted, said brake head is securely held in position on the end of the compression member by a nut 11, or any other fastening means. The parts being'assembled and secured in this manner, it will be readily seen that should it be desired at any time to' remove or renew the brake heads, all that is necessary is to unscrew nut 11, and slip ofi the brake head 3 the brake beam, as the nuts 10 firmly engage the tenslon. rod 2 and rigldly preserve the truss relation of the COIHPIQSSIOII and tension members.

It will thus be seen that I provide a very simple, strong and inexpensive brake beam with a minimum number of parts and which can be readily taken apart or the brake heads removed without in any way disturbing the adjusted or fixed relation of the other parts.

Having now fully described my invention, what I claim as new and desire to secure by Letters Patent is as follows l. A brake beam comprising a compression member, a tension member having means rigidly engaging each of its ends for firmly abutting against the ends of the compression member, brake heads removably secured over the ends of the compression and tension members, and removable means engaging the ends of the tension member for securing the break heads to the compression member.

2. A brake beam, comprising a compression Patented Apr. 18, 19111 "without disturbing any of the other parts of llt) member, a tension member having screw threads at its ends, a sustaining nut at each end engaging the threads of the tension member and abutting against the ends of the compression member, a brake head at 'each end of the compression member and member, a tension member having screw threads at its ends, a sustaining nut at each end seated in and abutting against the ends of the compression member and engaging 15 each of the free ends of the tension rod and 20 securing the member.

In testimony whereof I affix my signature in presence of two witnesses.
