' BRAKE HANGER.

Application filed May 26, 1925.

This invention relates to means for mounting the hanger which supports the brake beam and brake head of, a car brake mechanism, the object being to provide an inexpensive and easily assembled device whereby the hanger will be firmly supported and guarded while having ample play to accommodate the movement of the beam and head in applying or releasing the brakes. This object and other objects which will 1ncidentally appear in the course of the following description are attained in such a structure as is illustrated in the accompanying drawings, and .the invention resides in certain novel features which will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a side elevation of one embodiment of the invention;

Figure 2 is a top plan view of the structure shown in Figure 1;

Figure 3 is an end elevation of the same;

Figure 4 is a vertical section on the line 47-4 of Figure 1;

Figure 5 is a section on the line 55 of Figure 1;

Figure 6 is a detail perspective view of the hanger and the keeper block.

In the drawings, the reference numeral 1 designates a bracket which is preferably formed integral with the car truck side frame, a portion of the side frame being shown at 2. The bracket projects laterally from the side frame and on one side adjacent its outer end presents a horizontal rib 3 between an upper roove 1 4 and a lower groove 5, the face of the rib being slightly concave, as shown at 6 in Figure 5. The grooves 4 and 5 merge at their inner ends into openings 7 and 8, respectively, extending through anenlargement or block 9 on the bracket, the lower opening 8 also extending through the side frame. The hanger 10 is the closed loop now known and used having its lower end engaged or connected with the brake beam and head (not shown) in the usual or any ap roved manner. The upper end of the anger loop seats in the concave surface 6 of the rib 3 to rock thereon, and is supported by the holder or keeper 11. This holder or keeper is substantially U-shape in cross section whereby it is adapted to span the upper end of the hanger and fit in the grooves 4 Serial No. 32,978.

thicker than the Walls thereof and the mouths of the grooves are of less width than the interior of the grooves so that while the keeper may be slid endwise into or out of the grooves it cannot move sidewise when engaged therein. At the inner end of the keeper, pins 13 and 14 project therefrom in axial alinement with the thickened or enlarged side edge portions thereof, and these pins enter the openings 7 and 8 respectively, the upper pin 13 abutting the side of the truck while the end of the pin 14 is threaded, as at 15, to receive a nut 16 which is turned home against the inner side of the truck frame thereby positively securing the keeper in place. If desired, a lock washer, 17, may be fitted to the nut so as to resist loosening thereof from the vibrations due to travel.

It will be readily seen that I have provided a very simple and eflicient brake hanger support. The hanger will support the beam and head in proper relation to the wheel'whether the arts be new or worn and will swing readily without binding in the braking action without regard to the direction of rotation of the wheel. The engagement of the keeper and the bracket is such that the keeper cannot fall sidewise from the bracket and the nut 16 when turned home effectually prevents withdrawal of the keeper. The pin 13 by abutting the truck frame acts as a stop to limit the movement of the keeper toward the truck frame so that the, hanger cannot be cramped against the abutment 9 but will be held out of contact therewith so that it may respond quickly to the movements of the brakes. The parts can be readily assembled or disassembled so that repairs or replacements may be quickly made.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is 2-- 1. In brake mechanism, the combination of a bracket having a rib thereon and grooves above and below the rib parallel therewith, a brake hanger having its upper end seating upon said rib, a keeper spanning the end of the hanger and the rib and having its side edges engaged in the rooves, said grooves and side edges being 0 counterpart contour whereby to permit endwise but prevent sidewise movement of the keeper, and means to prevent endwise movement of the keeper.

2. In brake mechanism, the combination of a relatively fixed support, a bracket thereon, a' brake hanger sea-ting upon the bracket, a keeper engaging the hanger and holding it to the bracket, a stop on the l'ceeper abutting the. fixed support, and clamping means cooperating with the stop and the fixed support for securing the keeper upon the bracket.

3. In brake mechanism, the combination of a main support, a bracket thereon, a hanger seating on the bracket, an abutment block on the bracket having openings therel'zhrough, one of said openings extending through the main support, a keeper holding the hanger seated upon the bracket, pins projecting from the keeper into the openings in on, said bracket and fixed support having openings, a brake hanger seated on the bracket, a keeper engaging the hanger and holding it to the bracket, said keeper having a part extending through an opening in the bracket and transversely through an opening in the fixed support and secured to the latter,

and a. stop on the keeper and entering one of the openings in the bracket.

In testimony whereof, I have signed this specification.

GEORGE T. JOHNSON.
