Specification of Letters Patent.
Patented Oct. 2, 191?.
Application filed November 18, 1915. Serial No. 62,204.
To all whom it may concern:
Beitknown that 1, ROBERT J. SToKEs, a citizen of the United States, and a resident of Trenton, county of Mercer, State of New Jersey, have invented certain Improvements in Composition Linings for Brake-Shoes, of which the following is a specification.
My invention relates to certain improvements in brake shoes of the type in which the material is forced into a cavity in the brake shoe and shaped under pressure. The broad idea of this is set. forth and claimed in an application for patent filed by me onthe 30th day of December, 1914, under Serial No. 879,673, allowed September 24, 1915.
The object of my invention is to make a combination of asbestos fibers, small particles of metal, and a binder pressed into shape to form a brake shoe lining.
in the accompanying drawings:
Figure 1 is a perspective view of one form of brake shoe illustrating my invention;
Fig. 2 is a longitudinal sectional view through the shoe; and
Fig. 3 is a diagrammatic view of the composition prior to its insertion in the shoe.
1 is the shoes having a recess with undercut flanges 2 and having a series of barbs 3, which are preferably slightly undercut. These barbs are distributed over the surface of the recessed portion of the shoe so that when the composition is pressed into the shoe it will engage the barbs and will be held by said barbs and by the undercut flanges. It will be understood, however,
that the shape of the shoe and theshape of the device for retaining the material in the shoe may be modified without departing from the essential features of the invention.
4 is the composition which consists, in the present instance, of ground asbestos fiber and small sections of brass wire. The wire is thoroughly incorporated with the ground asbestos and the mass is impregnated with any suitable rubber composition or its equivalent. The mass is then placed in the shoe. A suitable die is provided of a shape to conform to the finished outer surface of the lining, the shape ofthe surface being indicated clearly in Fig. 1. The lining is then subjected to about 2000 lbs. pressure to the inch, which will cause the material to be forced into the cavity of the shoe, and, while under pressure, it is vulcanized by steam until the composition is thoroughly set, after which the pressure is removed, and the result is a lining accurately fitting the cavity of the shoe and held in the cavity by the undercut edges and the undercut prongs.
The surface prepared as above will wear away evenly and will provide a lining which will be able to withstand the hard may be prepared by. other methods than bygrinding and instead of thebrass wire, iron- 'or bronze wire may be used and, in some instances, particles of metal other than wire may be used which will thoroughly incorporate themselves with the asbestos so that when the mass is forced into the shoe it will form a substantial face.
I claim:
1. A brake shoes having a face consisting of a composition of ground asbestos fiber and metallic particles, the mass being im pregnated with a rubber composition and shaped under-pressure and vulcanized.
2. A composition for the wearing surface of a brakeshoe consisting of ground asbestos fiber, particles of brass wire thoroughly mixed therewith, and arubber. composition acting as a binder, shaped'under' pressure and vulcanized."
