BRAKE-SHOE.-
SPEOIFIGATION' forming part of Letters Patent No. 542,414, dated July 9, 1895.. Application filed May 9, 1895. SerialNo. 548,692. (No model.)
To all whom, it may concern:
Be it known that I, JOHN J. KINZER, Jr., a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered .certain new and useful Improvements in Brake-Shoes, of which improvements the following is a specification.
The invention described herein relates to certain improvements in brake-shoes, and has for its object a composition or combination of material adapted to take an effective grip on binder is of such a character as to require the tread of the wheel without the exertion of excessive pressure thereon, and in general terms the invention consists in the construction and combination substantially as hereinafter more fully described and particularly claimed.
In the accompanying drawings, forming a part of the specification, Figure 1 is a longitudinal section of myimproved shoe. Fig. 2 is a transverse section of the same. Figs. 3 and 4 are similar views illustrating a modification in the construction of the holding-shell.
In the practice of my invention I prepare a mixture of sawdust, comminuted iron, (as filings, turnin-gs, or chips,) plumbago, asbestos, and resin, which are thoroughly mingled together in about the proportions of five parts of sawdust, five parts of comminuted iron, one
part each of plumbago, asbestos, and resin, by I measure. These ingredients are thoroughly, stirred together by any suitable means in either a hot or cold condition. After being mixed 2. suitable binder, as linseed-oil, either raw or boiled, is added in sufficient quantity to thoroughly bind the ingredients into a solid compact mass or body. The mixture is .then solidly compressed in a shell 1 and allowed to harden and solidify therein. If the heat to cause it to harden and solidify, the shell, with the compacted material, is placed I. in a suitable ovenand baked.
face of the composition is given the proper concavity. As shown in Figs. 1 and 2, the shell'may be formed with side and end walls 2 and 3 for retaining the composition in place, or the side walls 2 may be lessened in depth or entirely omitted, as shown in Figs. 3 and 4. In the latter case the end walls are preferably bent in somewhat, so as to retain the composition in the shell, which is provided on its back with the usual lug 4, or any other suitable means for attachment to the hanger.
In pressing the composition into the shell it is given the usual concavity on its operative face, and also, by preference, a groove 5 is formed for the reception of the flange of the shell.
The composition, the proportions of the ingredients of which may be considerably varied, will readily take hold on the periphery of the wheel without the exertion of any considerable force, and full effective braking power can be attained without looking the wheel. The sawdust imparts to the shoe its frictional character, which is increased by the resin. The durability of the composition is insured by the comminuted iron and asbestos, while theplumbago will afford sufficient lubrication to prevent such friction between the shoeand wheel as will lock the latter, but will not materially lessen its frictional character.
I claim herein as my invention- 1. A composition for brake shoes consisting of sawdust, comminuted iron, asbestos, plumbago,,resin and a binder, substantially as set forth.
2. A composition for brake shoes consisting of sawdust, comminuted iron, asbestos, plumbago, resin and linseed oil, substantially as set forth.
In testimony whereof I have hereunto set my hand.
