E ATENT LOREN L. WHITNEY, OF HAMMOND, INDIANA, ASSIGNOR TO AMERICAN STEEL FOUNDRIES, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW JERSEY.
BRAKE-SUPPORTING ARRANGEMENT.
Application filed January 22, 1920.
To all coho 212 65 may concern Be it known that I, Leann L. VVHITNEY,
a citizen of the United States, residing at Hammond, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Brake-Supporting Arrangements, of which the following is a specification.
This invention relates to brake supporting a rrangements.
One object of this invention is to support brake rigging in a novel, simple, and efiicient manner, whereby the rigging is free to move longitudinally of the truck in a guided manner, and whereby internal friction is greatly reduced.
Another object is to provide simple and cflicient brake supporting and releasing arrangement adapted to meet the exacting requirements under service conditions.
These and other objects are accomplished by means of the arrangements disclosed on the accompanying sheet of drawings, in
which-- Figure 1 is a fragmentary side elevation of a railway car truck embodying my invention.
Figures 2 and 3 are sectional views taken, respectively, in the planes of lines 22 and 33 of Figure 1; and
Figure 4 is a fragmentary end view, parts being in section, of a modified form of the arrangement shown in the other figures of the drawings.
The various novel features of the invention will be apparent from the following description and drawings, and will be particularly pointed out in the appended claims.
Referring to the figures of the drawings, it will be noted that I have provided a railway car truck including cross tie members 10 to which brackets 11 are secured, said brackets being connected by spaced supporting bars 12 extending longitudinally of the truck. Interposed between these supporting bars 12 are brake levers 13 which are connected intermediate their ends by a pull rod 14., and connected at their upper ends to cooperating parts of the brake rigging by rods 15, the lower ends of the brake levers being pivotally connected to fulcrums 16 which in turn are connected to the brake beams in the usual manner.
To support the brake rigging and maintain same in its normal position and at the Serial No. 353,184.
same time permit proper movement of same longitudinally of the truck in a manner to meet operating requirements is a problem given much consideration, and in this paticular instance I have chosen to support the brake rigging by means of anti-friction rollers 17- which are rotatably mounted upon a pin 18 extending through the brake lever in each case, the rollers 17 being mounted upon opposite sides of the brake lever and riding upon the spaced supporting bars 12.
In Figure 1 of the drawings I have shown a modification in which the pin 19, in addition to extending through the brake lever 20, extends through arms or brackets 21 secured to the sides of the associated brake levers, the rollers 22 being mounted on either side of the lever and intermediate the latter and the associated bracket 21. In either case the rollers ride on the top of the supporting bars 12, and the levers move longitudinally of the truck and are guided in their movements and maintained in their proper positions against lateral movement by the supporting bars 12.
Also I have provided brake release springs 23 in the form of an open loop, one end being secured to the spaced supporting bars by a bolt 24, the free end of each of the release springs bearing against the associated brake lever near the lower end thereof, and preferably being split so that fingers 25 are formed to embrace opposite sides of the brake lever to maintain the spring in its operating position. The release springs 23 may be adjusted longitudinally of the supporting bars 12 and with respect to the levers to vary the effective action thereof. The bolt 24 extends between the bars 12 and this longitudinal adjustment is accomplished by loosening the nut on the bolt and sliding the bolt and spring along the bars in the desired direction. It will be understood that the end of the spring 23 secured to the bars 12 is split and the outer split portions bent up to embrace the outer sides of said bars for retaining the spring against, rotating.
It is my intention to cover all modifications of the invention falling within the spirit and scope of the following claims.
I claim:
1. In brake mechanism, a longitudinally extending supporting member, a brake lever. cooperatin means associated with said lever, and supporting member whereby the 110 lever is supported, and brake release means adjustably mounted on said supporting member and being operatively connected to said. brake lever.
2. In a brake mechanism, the combination of spaced supporting bars extending longitudinally of the truck, a pair of opposed brake levers connected by a pull rod and mounted intermediate the supporting bars,
