UNITED STATES PATENT QFFICE.
ELIZA D. MURFEY, OF NEW YORK, N. Y.
IMPROVEMENT IN MATERIALS FOR PACKINGS AND BEARINGS.
Specification forming part of Letters Patent No. 121,805, dated December 12, 1871.
To all whom it may concern:
Beit known that I, ELIZA D. MURFEY, of New York, county of New York, State of New York, have invented an Improvement in Packing and Bearing, of which the following is a specification:
My improved packing and bearing consists of sheets of paper impregnated with any suitable lubricant, as described in patents heretofore granted to me, combined with sheets of impregnated canvas, cloth, felt, or any filimentary material.
The fibrous sheet is laid upon a sheet of the impregnated paper or between two sheets of impregnated paper, or a sheet of impregnated paper is placed between two fibrous sheets, and the whole submitted toheat or pressure, or both, and thus condensed or cemented into one continuous sheet, which is wrapped round a mandrel to form a tube, or is cut into washers, molded, or otherwise reduced to forms necessary to render it available for packin gs and bearings in the various situations where the same are employed. When formed into Washers the outer or inner edges, or both, can be bound with thin metal to prevent the ravelin g of the fibers, and consequent unequal bearing when the washer is screwed up.
It will be apparentthat a series of impregnated sheets of both materials may be combined inthis way, forming a thick sheet or block, from which sections of the proper form may be cut or stamped. When impregnated fibers are used alone, either in sheets or otherwise, it is sometimes diflicult to impart the requisite stiffness to the packing Without using an excess of gum or parafiine in the impregnated compositions; but I have found that by combining, as described, the sheets of fiber and sheets of impregnated paper, the latter impart to the whole such rigidity that a large percentage of paraffine or its equivalent, otherwise necessary, may be dispensed with.
I claim As an improved article of manufacture, a packing and bearing material consisting of sheets of paper and canvas or its equivalent, impregnated, and combined as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
ELIZA D. MURFEY.
