Patented Nov. 5, isle.
application filed Eiiarch 29, 191%. Serial No. 225,536.
To all whom a may concern:
Be it known that l, Jenn E. "Pruner, a citizen of the "United States residing at Tucson, in the county of Finis and State of Arizona have invented certain new and usean Improvements in Brake-Shoes, of which the following: is a specification.
This invention relates to brakes, and more especially to removable shoes the object the same is produce an inn proved means for connecting the shoe with the brake bloc so as far as possible the generation of dust may be prevented.
Details are set forth loelow and reference is made to drawings, wherein l i'nre 1' is a side elevation Fig. 2 is a rear edge view, I
Fig. vertical section on the line 3-3 of Fig. 2
Fig. lis a rear edge view of the removed, and
Figs. and '6 horizontal sections on the lines 55 and 65 of Fig. l.
The bralre clock 1 is provided eyes 2 and 3 for receiving the links or other devices (not shown) by means 03E which this block is suspended from the brake beam in a manner not necessary to ampliffiy in the present specification. Also it will'not he necessary herein to detail means for actuating the beam to apply the brake and to release it. However, to those familiar with railway J3 lacing brakes, it is well known that ii? the cars of a train should become separated accidentally the brakes are applied with service application instead of emergency. lln my experience dust gets into the triple valve and prevents or retards the slide from worlnng, with the result that olten when the brakes are set they will not release and the casing of the triple valve must be tapped with a ham mer or the like, thereby resulting in great annoyance. 'l he object of the present invention is more particularly to produce a brake shoe in which the generation or" dust is minimixed, and by means 0 5 which'such dust as is raised is alloyed. lcloreover, is well known that the facing or lining of brake shoes wears away and in time must he replaced, and this necessity also has been taken -into consideration. lhe front face 4: of the therefor; and
holes or block 1 is preferably dished as seen in Fig. 1, being struck on a continuous are from its lower end upward, but its upper end is flattened as shown at 5; and this face is provided with an upright groove 6 dove-tailed in cross section and tapering downward as seen in dotted lines in Fig. 2, the groove at its upper end running out through the fiat face 5.
The facing or lining 10 has its from or active face dished as indicated at 1% and its rear face curved to conform with the dished face 4% or the block, said rear face being preferably inclined forward at its upper end as indicated at in a plane intersecting said curve. The rear face of the facing carries a dove-tailed tongue 16 tapering downward as best seen in Fig. 4, and the tongue 16 is intended to fit the groove 6. The downward taper or these elements prevents the facing from dropping off the block, because when the tongue is put into the groove and the facingis moved downward until the parts it closely, the facing can obviously go no farther. At this time registering notches 17 across the base of the groove and the rear wall of the tongue will produce a transverse opening, and through the same a pin 18 is driven as best seen in section in Fig. 3 and in plan in Fig. 6. This pin positively prevents the accidental rise of the facing, which is its tendency when the brake is applied while the car is being backed. When the facing is to be replaced, the pin is first withdrawn andthen by a gentle tap on the lower the facing the tongue is loosened from the groove and it may be readily" moved upward and a new facing put in its place. The parts are of the desired proportions and materials, and I reserve the right of making the facing of such material and of such shape that it will generate as little dust and produceas little wear on the tread of the wheel as possible.
What is claimed as new is 1 In a brake shoe, the combination with a block having its front face dished on an upright curve and the upper portion thereof flattened, said face being provided with an upright groove of dove-tailed cross section running out in the flattened face-and-taperend of In testimony whereof I affix my signature in presenc of two witnesses.
