FIBROUB LUBBIGATING-PACKING.

Application filed February 18, 1908. Serial No. 416,834.

To all whom it may concern:

Be it known that I, SAMUEL A. FLOWER, a citizen of the United States, and a resident of the borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvemerits in Fibrous LubricatingPacking, of which the following is a specification.

This invention relates to a fibrous lubricating packing and process for making the same. Its specificobject is to produce a fibrous packing which com rises fire-proofed resilient non-absorbent fi ers, and an absorbent fiber or material not subject to selfheating supported in pro er operative position by the said resilient bers;

In the accompanying drawing, which ex-- emplifies the packing, the resilient fibers are shown at 10, with the absorbent material 11.

To prepare the packing I mix by weight about fifty parts of cocoa nut fiber and about fifty'parts istle hemp, with twelve parts of muriate of ammonia, six parts of sulgfnte of soda, two parts of sulfate of copper and four parts of borax. The mixture is heated to the boilin point for about twenty minutes after whic the fibers are dried. These steps increase the natural resiliency of e fibers, fills the pores thereof ,to make t em nonabsorbent and fire-proofs them. I then take by weight 100 parts of jute, or fifty parts of cotton yarn, and fifty parts of jute yarn and s bmerge them in a solution of one part of bichlorid of mercury, with sixty arts of water for one hour, after which the ute and cotton yarn are dried. This pror uces an absorbent material not subject to self-heating. Then one part b weight of the prepared fire-proofed resi ient fiber is mixed with three parts b weight of the repared absorbent materia to redu e the ubricating packing. The pro uct thus obtained is specially applicable as a medium for lubricatin car axles. The resilient fibers of the packlng easily withstand the shocks conse quent to the rough service of a car axle, and

are not subject to destruction b reason of the heating of said axle, and wil hold the absorbent material in proper position in a journal box. The capillary attraction of the absorbent material will lubricate the 'ournal of a journal box byconductin a lu ricant to the surface of the journal. he eificiency of the resilient fiber is increased by reason of its ores-not absorbing any of the lubricant, the efficiency of the absorbent material is increased by reason of its not being subject to self-heating.

The invention may be modified by using for resilient fiber either wholly the cocoa nut fiber or the istle hemp, and the absorbent material may be either wholly cotton yarn, jute yarn, or jute.

Having described my invention, I claim:

1. A fibrous lubricating packing comprising a resilient fire-proofed fiber and an absorbent material.

2. A fibrous lubricating packing comprismg a resilient fire proofed fiber and a nonse f-heating absorbent material.

3. A fibrous lubricating packing compria ing fire proofed resilient cocoanut fiberand istle hemp, and a non-self-heating absorbent material.

4..A fibrous lubricatin ing a resilient fire proofe heating cotton am.

5. A fibrous ubricating packing comprising fire proofed resilientcocoanut fiber and istle hemp, and non-self-heating absorbent cotton yarn.

6. A fibrous lubricating acking comprisin" fire proofed resilient ist e hemp and nonseli heating cotton yarn.

Signed at the borough of Manhattan in the county of New York and State of New York this 13th day ofFebruary A. D. 1908.
