RELEASE-SPRING-SUPPORTING MEANS.

Specification of Letters Patent.

' Patented Mar. 30, 1920.

To all whom it may concern:

Be it known that I, ARMAND H. Parents,

a citizen of the United States, residing at- Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Release-Spring-Supporting Means, of which the following is a specification.

This invention relates to release spring supporting means.

One of the objects of this invention is to simplify and improve means for supporting brake release springs whereby the latter may be properly adjusted to equalize the releasing action.

Another object is to provide a novel combined release spring support and pull rod guide.

These and other objects are accomplished by means of the arrangement disclosed by the accompanying sheets of drawings, in which- Figure 1 is a fragmentary plan view of a railway car truck embodying my invention;

Fig. 2 is a fragmentary side elevation of the same;

Fig. 3 is a fragmentary end elevation of the same, parts being in section;

Fig. 4 is a detail view, parts being in section, showing my improved means for supporting the brake release spring and for guiding a pull rod; and

Fig. 5 is an enlarged detail view taken in the plane of line 55 of Fig. 4e.

Referring to the drawings, it will be noted that I have disclosed my invention in connection with a railway car truck including a frame 10 carried by wheels 11, only .one of which is shown.

This truck is provided with clasp brakes, that is, brakes mounted upon opposite sides of each pair of wheels. The brake beams 12 are supported by hangers l3 and are preferably held in balanced position by additional hangers 1 1 which are connected to fulcrums 15. Pivotally connected to the fulcrums are associated brake levers 16, to the upper ends of which are pivotally connected pull rods 17. An intermediate pull rod 18 connects intermediate points of the brake J levers This intermediate un rod 18 is guided in-its longitudinal brake applying and releasing actionby the guide portion 19 of a bracket 20 secured to the wheel guard 21 of the frame 10.

. This bracket 20 also serves another function in that a laterally extending arm 22 thereof underlies and supports a brake release spring 23, which loops downwardly and spreads outwardly to operatively engage with the brake beams at opposite sides of the pair of wheels. The release spring 23 is interposed between the arm22 and the under side of the wheel guard 21. A" Z- shaped bracket 24 is secured to the wheel guard by rivets 25, which. also secures the bracket 20 to the wheel guard. Interposed between the arm 26 of theZ-shaped bracket 24 and the arm 22 is a spacing member 27, which is of the same thickness as the release spring 23. This member 27 in addition to acting as a spacing member is provided with a plurality of teeth or serrations 28 cooperating with the teeth or serrated portion 29 of the brake release spring 23, whereb the release spring may be held in any adjusted position. 1

In positioning the release spring to properly equalize the brake releasing action, the spring 23 is set in place between the arm 22 and the wheel guard 21 with the serrated portion 28 of member 27 out of engagement with the teeth 29 of the release spring 23. The brakes are then applied, whereupon the serrated member 27 is set in place so that its teeth 28engage corresponding teeth 29 of the release spring 23, the bolt 30 being passed through the registering openings in the arms 22 and 26 and the member 27, whereupon the nut 31 is tightened. Under these conditions the release spring is locked or definitely set in a position whereby the adapted to meet the requirements for service conditions.

It is my intention to cover all modifica- V tions' of my: invention falling Within the q spirit and scope of the following claims.

I claim:

1. In b'ralie mechanism, the combination j of a brake release spring having portions cooperating With brakes on opposite sides of a Wheel, and means for adjustably securing the release spring in place for equallzing the releasing action.

2. In brake mechanlsm, thejicombination of a pull rod gulde bracket, a release spring 'carried'thereby and having portions cooperating with brakes on opposite sides of a Ewlieel, and means associated with said guide bracket and releasezspring whereby the'latter is adjustably secured in place. 7

3. In brake mechanism, the combination of a pull rod guide member carried by the Wheel guard, and a releasespring held in place between the bracket and Wheel guard. f l

4.,jIn brake mechanism, ,the combination of a pull rod guide mem'ber'carried by the Wheel guard, a release spring held in place between the guide member and Wheel guard, V

and means carried by the Wheel guard for adj ustably securing the spring in place 'for equalizing the releasing action of said spring.v V
