UNITED STATES PATENT OFFICE.
CHARLES E. VANCE AND JOHN A. VETTER, OF PITTSBURGH, PENNSYLVANIA.
PACKING AND PROCESS FOR MANUFACTURING THE SAME.
Patented Feb. 25, 1919.
No Drawing. Application filed October 26, 1917, Serial No; 198,615. Renewed January 9, 1919. Serial To all whom it may concern:
Be it known that we, CHARLES E. VANCE and J OHN A. VEI'IER, citizens of the United States, and residing in the city of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented or discovered new and useful. Improvements in Packings and Processes for Manufacturing the Same, of which the following is a speci- The basic material which we use is fibrous material, such, for instance, as flax, jute, cotton, rainie fibers, etc. 1
The fiber which we'use may be in loose material form or braided in square, round or oval form, as is usual with commercial flax packings, or in any other form.
This material we prefer to first bake, at a temperature which preferably does not-exceed 221 degrees Fahn, until the moisture is expelled. We removemoisture to the ex-.
tent of about 5 to 8% of' the weight of the material which is suflicient for practical purposes.
The material is then treated, either by dipping or brushing, with any of the commercial cellulose lacquers, such as cellulose acetate or cellulose nitrate lacquers to water-- proof the fiber. We have successfully used for this purpose the cellulose lacquer now Told on the'market under the name pyroxy- We may use with the. cellulose acetate lacquer about 5% of its weight in dissolved rubber, which rubber solution should erably contain about 2% of sulffir for the purpose of vulcanization.
In waterproofing the fiber after baking, we treat the fiber by dipping in cellulose acetate lacquer with or without the rubber. We then may, by brushing -ordip'ping, ap-
. ply outer wearing surface of cellulose pref-x nitrate lacquer. We improve the packing by repeated applications of either or both processes.
We dip in cellulose acetate lacquer to get penetration throughout the fiber. We prefer to then apply a coating of cellulose nitrate lacquer on the wearing surface only.
We may only use the cellulose acetate lacquer or we may apply the cellulose nitrate lacquer only or we may simply paint the wearing side with cellulose acetate lacquer.
We prefer to first bake the fiber to expel the moisture bu may omit the baking operation, and simp y waterproof the fiber as above described.
The cellulose solutions are thin enough to enter into and coat the fiber but do not cake in or fill the interstices between the fibers or between braided strands of fiber.
After the fibers have been treated with the cellulose solutions, the former are allowed to stand to'permit the solvent in such solutions to evaporate.
After the material thus treated has become dried, it is soaked in melted tallow, Japan wax, grease" or otherdubricant, at about 160 degrees Fahn, and subsequently cooled by airor a cold water bath.
\ The lubricant adheres to the outer surface of the individual fibers all through the packing but does not penetrate the fibers owing to the waterproofing.
The product is a very superior form of hydraulic packing which retains its elasticity. and lubricating values in the presence of either warm or cold water. The expulsion of the moisture followed by the waterproofing operation or the waterproofing alone prevents the absorption of moisture when the packing is in use, or when in storage.
We find, that the strength and elasticity of the fibrous material are greatly increased by the expulsion of the moisture, and that this improvement is further augmented by the waterproofing. This increasei'of stren h is several times that exhibited by fiber whlch .has been lubricated Without previously expelling themoisture or applying the above treatment.
The addition of the rubber to cellulose acetate lacquer adds further flexibility and durability, We may or. may not use the rubber.
What we desire to claim is:
,1. The process of manufacturing hydrau-' lic packing consisting in first expelling the moisture from the fibrous aterial, then treating the same with a cel ulose solution to render it waterproof, and then coating the fibers with lubricant.
- 3. The process of manufacturing hydraulic packing consisting in first expelling the moisture from fibrous material, then waterproofing the same by means of a cellulose solution with a rubber content, and then introducing lubricant into the same.
4. A new and improved hydraulic packing composed of fibers treated with cellulose solution and carrying a lubricant.
5. A new and improved hydraulic packing composed of fibers from which the moisture has been expelled, treated with cellulose solution and carrying. a lubricant.
Signed at Pittsburgh, Penna., this 19th day of October, 1917.
