Definitions
- each piece or section is made of a rubber-surfaced strip of Woven inaterial, having its, edges lapped and united to form the tube, some diicultyhas been experienced in making the seam orjunction at the lapped edges tight.
- My invention further consists in the use of a welt-strip. formed ot' rubber and laid under the inner edge, or-against the inner surface, so as to cross or cover the edge, and I also prefer to make the same strip cover the fastenings, it' fastenings be used.
- My invention consists prilnaril y in hydraulic hose made of a strip of rubber-surfaced Woven material, which being formed into a tube by lapping' tbe opposite edges is vulcanized to homogcneously unite the rubber surfaces at the respective sides ot' the edge, to imperviously close the seam or junction, such invention being preferably supplemented by the use of the Welt. l
- a denotes the strip of cloth; b and c the edges brought together and lapped and united to form the tube; e, the rubber surface of the strip; f, the Welt-strip.
- the tube is vulcanized by iilling it with French chalk, or other suitable material, to prevent adhesion of the inner surfaces ofthe tube, and, if necessary, to create pressure, and then subjecting it to the action of steam or other heat; or the tube may be tlled with steam'under pressure, or any other suitable method ot' vulcanization may be employed.
- a hose which, being made of a rubbersurfaced strip of fibrous material with edges lapped and united to form the tube, is vulV 'canized to close the seam or junction, sub-
