IMPROVEMENT IN PROCESSES FOR THE MANUFACTURE OF INDIA-RUBBER HOSE.
Specification forming part of Letters Patent No. 26,276, dated November 29, 1359 reissue No. 5,111, dated 00- tober 22,1872; extended seven years; reissue No. 6,545, dated July 13, 1875; application filed December To all whom it may concern Be it known that I, THOMAS J. MAYALL, formerly of Roxbury, in the county of Norfolk and State of Massachusetts, now of 130s ton, Sufiolk county, Massachusetts, have invented a new and useful lugprovement in the Manutactnre of India-Rubber Hose 0'! Tubing,
- of which the following is a full and exact description: I J Ehe object of my invention is an india-rubberhcseyvhose durability will not be impaired by the premature decay of the canvas, upon which its strength depends.
The indie-rubber hose or tubing in common use previous to my improvement is composed .of layers of canvas coated with india-rubber and vulcanized, the art of making which is well known. The trouble in the use of this hose arises from the fact that the canvas decays rapidly, either in consequence of being wet or of the effect of the sulphur with which the rubber is vulcanized, and the hose becomes unable to endure the watcnpressure to which it is subjected. I have discovered how this trouble may be averted and a hose produced which will not prematurely decay. The mode I employ is to treat the fibrous fabric. on which the strength of the hose depends, with, antiseptics, either by immersing the fabric in the antiseptic and afterward drying it, or by placing it in any suitable vessel and exhausting the air, so that the antiseptic will be forced in by'pressure,,or in any other openmammr.
oil of tar, or crudccar bolic acid, as it issometimes called, obtained in the destructive distillation of carbonaceous substances.
I find that a solution containing from thirty an equivalent antiseptic, with the fibrous 111mg terial of the same, substantially as describedg? THOS. J. MAYALL.
