BRAKE-RELEASE SPRING.

Application led August 27, 1917.

1 'o CLU, whom t may concern:

Be it known that I, CHARLES D. YOUNG, a citizen of the United States, residing at l/Vilmington, in the county of New Castle and State of Delaware, have invented certain new and useful Improvements in Brake- Release Springs, of which the following is a specification,

This invention relates in general to brakerclease means and particularly to a release mea-ns for locomotive, car,'or tender brakes, and it has for its object the provision of a spring for the purpose specified which will be effective in operation, simple in construction, and adapted to be most easily and readily applied, and one which requires no special bolts or other fastening means to hold it in its place. A clear understanding of this invention can best be obtained by referring to the accompanying drawings forming a part of this application, which illustrate it as applied to a railway car truck.

,Figure 1 of the drawings is a partial perspective view of a car truck showing my releasespring applied thereto; and Figs. Q., 3, and 4 are various Views of the spring by itself.

Referring to Fig. 1 the car wheel is indicated b y the numeral 1, the brake-head by 2, the brake-shoe by 3, the brake-beam by et, the hanger by the bolster by 6, the bolster spring by 7, and the truck frame by 8. The hanger is pivoted to the hanger bracket '9 by means of the hanger bolt 10.

The release spring 11 is, as shown, of a general U-shape inverted withof-set eye portions 12, one in each arm of the U, which are so arranged that the hanger bolt 10 projects through the said eye-portions. thereby positioning and fastening the spring. This fastening means is the only one provided, no special or eXtra screws, bolts or parts of any kind being necessary. The portion of the spring projecting above the hanger-bolt bears against the hangerbracket and each of the two arms portions projecting below the bolt is provided with a hook portion 13 adapted to engage the arms of the brake hanger, all as clearly shown in the drawings, from which it will Specification of Letters Patent.

Serial No. 188,356.

be seen that movement of the brake-beam toward the wheels, which occurs when braking pressure is applied, puts the spring under tension. Upon release of the brake the springs will immediately throw the brake hangers away from the wheel thereby taking the brake shoes out of contact therewith. lt is, of course, understood that there are two such springs, one at each end of the brake bea-m.

Tt will be seen that while I have shown as a preferred form the use of a wire of round cross-section and have supported my spring from the bolt of the hanger, a like construction could be employed with the use of flat spring supported from the lug itself and not necessarily embracing the bolt but passing through supporting slots on either the lug or the lug and bolt.

I claim:

1. The combination with a hanger bracket, a brake beam hanger and the hanger bolt, of a spring bearing against said bracket and said hanger and supported from said bolt, said spring normally tending to hold the hanger in release position.

2. The combination with ahanger bracket, a brake beam hanger and the hanger bolt, of a U-shaped spring each arm of which engages an arm of the hanger and the base of which engages the hanger bracket, there being an off-set eye portion in each arm intermediate the ends adapted to be engaged by the hanger bolt.

3. The combination with ahanger bracket, a brake beam hanger and the hanger bolt, of a spring supported intermediate its ends and bearing against said bracket and said hanger, said spring normally tending to hold ythe hanger in release position.

f1. The combination with ahanger bracket, a brake beam hanger having two arms, and a hanger bolt, of a U-shaped spring the top of which engages the bracket and which has each of its free ends shaped to embrace an arm of the hanger, said spring having an eye portion intermediate its ends adapted to be engaged by the hanger bolt.

In testimony whereof I have hereunto signed my name.

CHARLES D. YGUNG.
