CHARLES I-IAINES I/VILLIAMS, OF CHICAGO, ILLINOIS, ASSIGNOR TO CHICAGO RAIL- WAY EQUIPMENT COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

BRAKE-BEAM RELEASE AND SUPPORT.

Specification of Letters Patent.

Patented July 25, 1922.

Original application filed July 15, 1920, Serial No. 396,438. Divided and this application filed June 16,

To all whom it may concern:

Be it known that I, CI-rARLEs IIAINES l/VILLIAMs, a citizen of the United States, residing at Chicago, Cook County, Illinois, have invented a certain new and useful Impro vement in Brake Beam Releases and Supports, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference be ing had to the accompanying drawings, forming part of this application, in which Figure l is a side elevational view of my improved brake beam release and support.

Figure 2 is a plan view of the same.

Figure 3 is a side elevational view of a modified form of release-support.

Figure el is a plan View of the form shown in Figure 3.

This invention relates to a new and useful improvement in a brake beam release and support, the object being to construct a simple and easily applied device of the character described, all of which will hereinafter be described, pointed out and claimed.

This present application is a division of an application filed by me July 15th, 1920, Serial No. 396,438.

In the drawings, 1 indicates a portion of a spring plank, being part of a car truck to which my improved release-supports are secured. This spring plank is shown in the form of a channel with its flanges presented upwardly. Referring to Figures 1 and 2, 8 indicates the body portion of a supporting member which is secured to the spring plank of a truck, said supporting member preferably having two tongues 9 formed on each side thereof and beyond the marginal edge of the spring plank 1, said tongues being bent downwardly and then upwardly in curved lines so that their free ends engage the face of the compression member 3 of the brake beam. Said tongues, being composed of spring metal, are yielding and tend to move the brake beam to a released position after the brakes are applied. It will be noted that these tongues have two points of contact- Serial No. 478,137.

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, also not shown, the tongues 9 will be placed under tension, and when the brakes are released, these tongues act to retract the beam, and by the two-point contact above referred to, move the same in a straight line to its released position.

In Figures 3 and 4, I have shown tongues 13 cut from the sides of the supporting member and engaging the compression member of the'beam, these tongues extending up wardly over and in front of the beam, instead of under the beam, as shown in Figures 1 and 2. I

In Figure 2, I have shown the support 8 as extending outwardly in a straight line to serve as an inclined track supporting member for a third point support; while in Figure 4c, the ends of the supporting member are bifurcated to form diverging mem-' bers 14 whichmay serve as fourth point supports. It is, therefore, obvious that the release-tongues may be formed integral with the track supporting members of a third or fourth point support for brake beams.

What I claim is:

1. A third or fourth point support for brake beams having integral yielding members for engaging the beam at two points toforce the beam to a released or retracted position.

.2. A third or fourth point support for brake beams having integral yielding means for engaging the beam at each side of the longitudinal. center thereof to force the same to a released position.

3. A third or fourth point-support for brake beams comprising a member secured to the car truck and extending under the beam, and a retractive means integral with said support and engagingthe beam to force it to a released position.

In testimony whereof I hereunto aiiix my signature this 9th day of June, 1921.

" CHARLES, HAINES WILLIAMS.
