Specification of Letters Patent.
Patented Nov. 28, 1916.
Application filed October 2, 1916. Serial No. 123,257.
To all whom it may concern Be it known that I, WILLIAM C. HEDGCOC-K, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Emergency-Brake Beam Supports, of which the following is a specification.
My invention relates to railway car brakes and has particular reference to a novel emergency supporting means. The construction here illustrated is an improvement on the construction of the patent to Elliott, No. 1,147,793 dated July 27, 1915.
It has been found in practice that the excessive vibration of the trucks of the cars to which these devices are applied causes excessive wear. Particularly in this true where the horizontal bar which serves to underlie the brake beams is supported by hangers in the form of plates having transverse apertures, the area of support being only that of the width or thickness of the material. It is found that the bar became weakened by being cut vertically. As a means for obviating this difiiculty I have provided for a practically unlimited area of support for the bar by turning up or upsetting thelower end of the bar, the top or horizontal surface of the upset portion lying in the plane of the bottom of the aperture through the hanger. By this means a wide bearing area'is provided.
The invention will be more readily understood by reference to the accompanying drawings, wherein Figure 1 is a side elevation showing a car truck side frame in dotted lines, the brake beams in section and my improved supporting device in elevation; Fig. 2 is a plan View showing the relation of the bar to the brake beam; Fig. 3 is a sectional view on the line 3-3 of Fig. 1;-Fig. 4 is a fragmentary elevation of a slight modification, and Fig. 5 is a sectional View on the line 55 of Fig. 4.
Referring more particularly to the drawings, it will be seen that the side frame is indicated at 10, the sprin plank at 11 and the brake .beams at 12. cated near each end of the channel spring plank 11 are depending hangers 18, the upper ends of which are hooked over the flanges of the channel and the lower ends of which are upset or bent at a right angle, as indicated at 14. An aperture 15 is provided in the hanger, the lower extremity of the opening being in a plane with the top surface of the offset portion 1.4 of the hanger. A bar 15, which is preferably of I beam construction, is passed longitudinally through the apertures 15 in the hangers and is retained in position by suitable keys 16. By reason of the construction shown, it will be seen that a wide shelf is provided upon which the bar may rest, and that the wear due to vibration will be. reduced materially.
In Figs. 4 and 5 the modification which I have illustrated consists in increasing the area by upsetting the end of the hanger 18, thereby providing two shelves 19, 20, one at each side of thehanger, the top surfaces of both of which shelves being as heretofore in the plane of the bottom of the opening,
which I have indicated at 21, through the hanger.
Obviously other modifications may be made than those illustrated and I do not wish to be limited to the exact forms herein shown and described.
I claim: p
1. In a device of the class described, the combination of a hanger, a horizontal bar engaging an aperture in said hanger, the lower end of said hanger being bent angularly to provide an increased bearing area for said horizontal bar, substantially as described.
2. In a device of the class described, the combination of a pair of vertical hangers, a horizontal bar engaging an aperture in each hanger and a lateral shelf on the lower end a bar adapted to engage said hanger by a Signed at Chicago, Illinois, this 27th day longitudinal sliding movement, and a shelf of September, 1916.
formed as a part of said hanger and adapted WILLIAM C. HEDGCOCK. to underlie said bar and provide a relatively lVitnesses: 5 wide support for said bar, substantially as GEORGE A. PETERSON,
described. GEORGE S. CHILES.
