No Drawing.
To all whom it may concern:
Be it known that I, WILLIAM D. PARDOE, a citizen of the United States, and a resident of Trenton, Mercer county, State of New Jersey, have invented Brake-Linings and Methods for Preparing the Same, of which the following is a specification.
@neobject of my invention is to provide an improved lining for clutches, brakes and the like which shall be capable of withstanding stresses placed upon it under operating conditions, shall possess good wearing surface and be of such a nature as not likely to be damaged by overheating.
In carrying out my invention I provide a solution whichin a typical case may con sist of twenty-six ounces of asphalt, four ounces of red lead, five ounces of sulfur, two ounces of hexamethylenetetramin in two thousand eight hundred and forty c. c. of gasolene and three hundred and fifty c. c. of benzol. 'Ihe woven or braided cloth or tape to be treated, which may be made of flax, hemp, asbestos or other fibrous material, is placed in this solution for a time suflicient to permit it to be completely impregnated or saturated, after which it is removed from the solution, thoroughly dried, and subjected to a relatively high pressure such as fifteen hundred pounds to the square inch, being at the same time heated to a temperature of from 300 to 400 F.
As a result of this treatment the materials in the fabric are vulcanized to a greater or less extent and the quantity of fixed carbon therein is materially increased, so that the finished product has an unusually high coefiicient of friction, possesses good wearing qualities, and will not become sticky when subjected to the heat to which it 13 frequently exposed under operating conditlons. Moreover the finished product produced as above described is hard, unaffected by oil and heat, and is as nearly uninflammable as it is possible to make. It is noted that the substance referred to above as asphalt is preferably the mineral compound known as gilsonite, in an'oxidized or blown form, although other hydrocarbons of an asphaltic nature maybe employed without departing from my invention.
The ,hex'amethylenetetramin is employed to'accelerate 'thevulcanization of the ma- Specification of Letters Patent.

found the latter to give the best results.
Again, some solvent'other than a mixture of gasolene and benzol may be used for dissolving the materials specified, such for example as carbon bisulfid or carbon tetrachlorid,
Eu; I preferably utilize the substances specie It i to be noted that the lead oxid and hexamethylenetetramin may be altogether I omitted in some cases although I have found them to be particularly valuable in materially hastening the vulcanizing or oxidizing operation. 3

oxid of lead, sulfur, and an oxidation ac- I celerator; and thereafter treating said fabric to vulcanize the material/with which it is impregnated.
