WAGON BRAKE-SHOE- SPECIFICATION forming part of Letters Patent N0. 780,602, dated January 24, 1905.
' Application filed May 10, 1904. Serial No. 207,211.
of reference marked thereon, in which Figure l is a perspective view of the shoe,
showing the same properly attached to a brake-beam and illustrating a portion of a wagon-wheel. Fig. 2 is adetached view-of the brake-shoe clamp. Fig. 3 is a detached view of the movable clamp-plate. Fig. 4 is a longitudinal section of the brake-beam and a sectional view of the clamp and brake-shoe.
The present invention has relation to wagon brake-shoes, which consists in the novel construction hereinafter described, and particularly pointed out in the claims.
Similar numerals of reference indicate corresponding parts in all the figu res-of the draw.
1ngs.
In the accompanying drawings, 1 represents a portion of the brake-beam, which is constructed in the ordinary manner and is supportedupon the running-gear of a wagon in the customary way. 7
To the outer ends of the brake-beam and at pointsoppositethe tires of the wagon-wheels are located the shoe-clamps 2, which clamps are bolted to the beam 1, substantialy as shown in Figs. land 4. 3 r
The clamp 2 consists of the right-angled flanges 3 and 4. The flange 3 is provided with the rib 5, which rib is located upon the inner face of the flange and at the apex of the angle bounded by the inner face of the flange 3 and the face of the clamp 2.
The flange 3 is provided with the screwthreaded aperture 6, which receives the binding-screw 7, as illustrated in Fig. 4.
The clamping-plate 8 is located when placed in proper relative position as illustrated in Fig.4 and is designed to clamp the brakeshoe 9.
The'clamp-plat'e 8 is provided with the upward-extending flange 10, which flange is spaced from the clamp-plate 8 and is so spaced for the purpose of providing a means for placing the clamp-plate 8 proper upon the flange 3, by which arrangement the flange 10 is located uponthe outer face of" the flange 3 and the clamp-plate proper located upon the inner face ,of the flange 3 and in position to engage one side of the shoe 9, as illustrated in Figs. 1 and 4. Y
The flange 10 is held in proper spaced relation by means of the integral connecting-bars 11, said bars being of such a length that lateral movement may be given to the plate 8 by means of the screw 7 For the purpose of assisting in holding the clamping-plate 8 said plate is provided with a recess 12, which recess fits the rib 5, so that when downward pressure is brought upon the brake-shoe the upper end of said rib will assist in holding the clamping-plate 8 in proper relative position and to a certain extent remove the strain from the screw 7.
In use the brake-shoe 9 is placed in position illustrated in Figs. 1 and 4, after which the screw 7 is turned in the direction to'force the clamping-plate 8 against the outer face of the shoe, and thereby bind the brake-shoe 9 between the flange 4 and the clamping-plate 8. By providing the flange 10 it will prevent any tilting of the clamping-plate 8 if in the event the edge of the brake-shoe 9 is'uneven, owing to the fact that the flange 10 will strike the screw 7 and stop any tilting movement, by which arrangement the clamping-plate 8 will be forced firmly against the edge of the clamping-shoe 9, and thereby secure the proper clamping of said shoe.
Havingfully described my invention, what I claim as new, and desire to secure by Letters plate and a brake-shoe located between the clamping-plate and one of the flanges of the shoe-clamp, substantially as and for the pur- 5 pose specified.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
CYRUS DECKARD.
