WILLIAM H. BATES AND HUGH FAULKNER, OF LEICESTER, ENGLAND, ASSIGNORS TO EZRA THOMAS SAW'YER, OF EAST HAMPTON, MASS.
IMPROVEMENT IN THE MODES OF MANUFACTURING WATER-PROOF TUBING.
Specification forming part of Letters Patent N 0. 129,266, dated July 16, 1872.
Specification describing an Improved Mode vented by WM. H. BATES and HUGH FAULK- NER, of Leicester, En gland.
Figure 1 represents a sectional elevation of a braiding-machine. Fig. 2 is a sectional side verse section of the same. I
Our invention consists in the method h rein after described of makin g water-proof braid. A in the drawing represents the core. This core is made of India rubber, cylindrical, solid, and of proper length. It is drawn through a braiding-machine, B, while the fabric 0 is being braided about it. In making water-proof braid or tubing it is desirable to apply the braiding directlyto the lining-tube. Hence the rubbertube D (see Fig. 2) is first drawn over the rubber core A. The core is then drawn through a box, E, of rubber cement or solution, and thus receives a coating, whereby the threads of braid are braided and firmly embedded and united to the lining D. The braided and lined tube is then drawn through a heated cylinder, F, wherein the volatile solvent of the solution will be evaporated, leaving the braid and inner lining united. After the core has been covered with the braid it is, at any convenient time, stretched lengthwise. This reduces its diameter, and greatly facilitates the removal from it of the tubular braid.
Having thus described our invention, What I Witnesses:
ALFRED BROMWICH, STEPHEN PRAKE.
