Applicationfiled Ju1y'15,

improved brake beam release and support showing the same, carried by the spring plank of a truck. V

Fig. 2 is a plan view of theform shown I in Fig. 1.

Fig. 3 is a modified form of the release and support.

Fig. 4 is a. plan view of a form shown in Fi 'Ihis invention relates to new and useful improvements in brake beam release and support, the object being to construct a simple and easily applied and repairable device of the character described, all as will be hereinafter described and afterwards pointed out in the claims.

In allof'the figures of the drawing, "1 indicates a portion of a spring plank, being a part of a car truck to which my improved release and support are secured. This pring plank is shown in the form of a channel with its flanges presented upwardly.

Referring to Figs. 1 and 2, 2 indicates the body portion of the supporting member which is secured to the spring plank of the truck, the extremities of said body portion being flared in opposite directions, as at 2 the ends of said flared portions being bent upwardly, as at 2', for well understood purposes. The body portion 2 may be formed in one piece and the flared extremities made integral therewith, but, if desired, the body portion may be split or divided into two parts so that the flared portions can be more widely separated as, for instance, when they are to be used particularly in connection with widely separated fourth point sup ports. 1

3 indicates the compression member of the brake beam, 4 the strut and 5 the tension member thereof. 6 indicates a retracting and releasing member secured to the brake BRAKE-BEAM nEnEasE ANn Samar. I

1920. Serial N s9e,43s. I I 4 beamsupport or tothe' spring plank, as the caseimay be, the ends of which retracting member are'bifurcated so as to receive the strut in said bifurcation, the fingers 7, or the free ends of the retracting member, be- 111g resilient andhaving two points of contact with the compression member of the brake beam, one on each side of the center thereof. When power is applied to the brake beam to move the shoes, not shown, carried at each end thereof, against the wheels, the fingers 7 will beplaced under tension and when the brakes are released, these fingers act toretract the beam, and by the two-point contact above referred to move the samein a straight line to its released position. l

In Figs. 3 and 4, I have shown two releasing members 10 for engaging the compression member 3 of the brake beam, one of said releasing and retracting members 10 being mounted upon a flaring end of the support and the free resilient ends of said retractingmembers engaging the brake beam on each side of the center thereof. In this form of my invention I have shown the flared ends of the support bent upwardly, these inclined ends carrying a saddle bar or plate 11 with which the chair or rubbing shoe 12, forming the third point support for the brake beam, cooperates.

I have shown a modified form of the brake beam release and support in a companion application, filed June 16, 1921, Serial Number478,137.

What I claim is:

1. A third or fourth point support for brake beams the same comprising a body portion secured to a portion of the car truck, the extremities of said body portion being flared in opposite directions.

2. A third or fourth point support for brake beams the same comprising a body portion secured to a portion of the car truck, the extremities of said body portion being flared in opposite directions and bent upwardly at their extremities.

3. A third or fourth point support for brake beams the same comprising a body portion secured to a portion of the car truck, the extremities of said body portion being flared in oppositedirections, and a saddle bar or plate secured to said flared extremities.

4. A third or fourth point support for brake beams the same comprising a body portion secured to a portion of the car truck, the extremities of said body portion being flared in opposite directions and bent upwardly at their extremities, and an inclined saddle bar or platesecured to said flared extremities. I

5. A bifurcated retraction member for brake beams Whose free ends are designed to engage the beams at tWo points.

' 6. A bifurcated retraction member for brake beams whose free ends are designed to engage the beams at tWo points, one of such points being on each side of the center ofthebeam.

7. A third or fourth-point support for brake beams comprising a member secured to the car truck and extending under the beam, and a retraction means Which engages the beam at two points.

In testimony whereof I hereunto afiix my signature this 22nd'day of June, 1920.

CHARLES HAINES WILLIAMS.
