Description

Feb. 10, 1931. D. HxNDAHL BRAKE BEAM SAFETY SUPPORT Filed April 4, 1928 Patented Feb. 10, 1931 DAVID HINDAHI., or CHICAGO, ILLINOIS BRAKE-BEAM SAFETY SUPPORT Application led April 4, 1928. Serial No. 267,328.

As is `well known, brake beams frequently i become detached from the trucks and will fall upon the track while the train is in motion, thus causing serious wrecks, unless some means is provided to prevent this difficulty. It is customary, therefore, to provide an additional support for brake beams, which will catch them in the event they fall and prevent their contact with the track. Examples of such structures Vare shown in the patents to I-Iorrigan No. 1,303,064, May 6th, 1919, Grone No. 1,655,7 56, January 10th, 1928, and Rice No. 1,656,075, January th, 1928. My invention has for its object to provide a support of this kind having a minimum number of parts, a simplicity of structure, improved means of attachment to the spring plank, and permanent security without the use of rivets or other additional devices for securing the structure to the spring plank.

Referring to the accompanying drawings,

Fig. 1 is a side elevation, partly in section, showing one form of my invention. Fig. 2 is lan end elevation, partly in section, showing another form of my invention. Fig. 3 is a plan view of the spring plank with my supporting means shown in Fig. 2 applied thereto. Fig. 4 is a side elevation, partly in section, showing the spring plank with my invention applied thereto and portions of the brake beams. Fig. 5 is a perspective view of my bracket.

In the drawings, A is the spring plank which is provided at suitable points with spaced apertures a, which may be located as shown in the bottom of the spring plank. These apertures may be placed as shown in Fig. 1 at a point adjacent the middle portion of the spring plank, or as shown in Figs. 2 and 3 at points nearer the wheels. As shown in Fig. 1, there will be one set of these apertures, while as shown in Figs. 2 and 3 there will be a set of apertures adjacent each wheel for a purpose presently to be described.

These apertures in the spring plank receive a rigid supporting bracket B, which may be a forging or a casting or the like formed preferably of a strip of material turned down at each end b, these ends b being provided with suitable apertures b. It will be noted that the bracket is of less length than the width of the spring plank. The bracket B is simply dropped into position through the apertures a and is thus loosely sup` ported on the spring plank with the depending ends b in position below the spring plank to receive a supporting bar C, which is placed in position through the apertures b. As shown in Figs. 2, 8 and 4t, it may 60 be held in place by cotter pins d or other suit able means. The bar C as shown in these figures has no other function than to act as a safety support in the event of the brake beams falling.

In the form shown in Fig. 1 a single supporting bracket is located near the middle portion of the spring plank, this bracket being supported by suitable apertures formed in the spring plank at this point and the connecting rod for the brake levers is passed through the bracket. The connecting rod being thus supported by the bracket has, in addition to its normal function, that of a supporting member C, which is prevented from falling should the brake beams become detached, and will in turn act as a safety support for the brake beams and all brake beam parts.

It will be seen from the above description that I have provided Va safety support for brake beams, extremely simple in construe-p, t-ion, easily manufactured and assembled and one which forms a positive secure support, which transmits the strains placed upon it 35 directly to the spring plank without the use of rivets or other securing means.
