Description

July 21, 1931. Q H. WRIGLEY 1,815,175
RAILWAY CAR FRAME Filed Sept. 6, 1929 Patented July 21, 1931 STATES PATENT OFFICE HENRY I. WRIG'LEY, OF CHICAGO, ILLINOIS, ASSIG-NOR TO UNIVERSAL DRAFT GEAR ATTACHMENT 00., A CORPORATION OF ILLINOIS RAILWAY CAR FRAME Application filed September 6, 1929.
The invention relates to means for chang ing the direction of the pull from hand brake operating mechanism, mounted near the top and at the end of the car, to the brake 5 mechanism located below the car and intermediate of its ends.
The object of the invention is to provide an improved support for the sheave at the bottom of the car end, about which the brake chain turns, and to reinforce the end sill of the car to enable it to withstand the severe stresses to which it is subjected in the application of the brakes.
The invention is hereinafter described and is illustrated in the accompanying drawings, in which:
Fig. 1 is adetail vertical section through the end of the car, the brake mechanism applied thereto being shown in elevation; and
Fig. 2 is a detail end elevation of the car end, showing the brake mechanism.
The end wall of the car is shown at 10 and the end sill at 11. The hand mechanism for actuating the brakes is secured to the end of the car, near the top thereof, the hand wheel 12 being carried by a. horizontal winding shaft and so positioned as to be within easy reach of the brakeman occupying the running board 13. The brake actuating mechanism illustrated is of the power multiplying type now in common use and transmits power to the brakes through a pull rod 14 and a chain 15, the latter turning about a sheave 16 supported from the end sill 11.
This general organization of the car and its brake mechanism is in common use but with unsatisfactory results for the reason that no means has heretofore been found to support the sheave 16 so that the sill 11 will not be distorted by the twisting strains transmitted to it, especially when the power multiplying type of brake mechanism is em ployed.
, The present invention overcomes this difliculty. The bracket carrying the sheave 16, and generally designated by the numeral 17 is formed of an angle bar bent to U-shape, one of the flanges 18 of the end portions of the bracket arms being applied and rigidly secured to the inner vertical face of the sill Serial No. 390,733.
11 and preferably extending substantially across such face.
Immediately below the sill 11 the bracket is preferably bent outwardly so that its loop not only projects below the sill but beyond the face of the wall 10. The flange 18 of the bracket being applied to the face of the sill, its other flange 19 projects backwardly therefrom and downwardly from the outwardly inclined lower portion of the loop. The sheave 16 is located within the loop of the bracket and is mounted upon a shaft 20 journaled in the flange 19.
By this construction the sill 11 is reinforced sufliciently to withstand the twisting strains transmitted to it through the bracket as distortion of the sill cannot take place unless the flange 19 be bent in the direction of its width and the bracket itself resists these stresses in the direction of its greatest transverse strength. The flange 18 gives great strength to the bracket to resist any blows which it may accidentally receive.
The portion of the flange 19 facing the periphery of the sheave is inclined and serves as a feeder for the chain to the sheave, pre venting the chain from buckling and consequently jamming upon sudden release of the brake.
I claim as my invention:
1. In a car frame, in combination, an end sill, a L -shaped bracket-bar of angle section, the ends of the bracket bar being attached to a vertical face of the sill and its loop being outwardly inclined therefrom, and a sheave pivotally mounted within the loop of the bracket.
2. In a car frame, in combination, an end sill, a U-shapedbracket-bar of angle section, the ends of the bracket bar being attached to a vertical face of the sill and its loop projecting below the sill, and a sheave pivotally mounted within the loop of the bracket.
In testimony whereof, I have hereunto set my signature.
HENRY I. VVRIGLEY.
