IMPROVEMENTS IN THE MANUFACTURE OF WATERPROOF CLOTH
Year: 1884

page_text: I ISIDOR FRANKENBURG of 88 Greengate, Salford in the County of Lancaster,
India-rubber manufacturer do hereby declare the nature of said Invention for
IMPROVEMENTS IN THE MANUFACTURE OF WATERPROOF CLOTH, to be as follows:-
The object of my Invention is to make a waterproof cloth that is stronger and
lighter than the common waterproof cloth and that will have the appearance of
ordinary cloth.
In performing my Invention I coat the yarn for the warp with a solution of
rubber or other waterproof material or I coat with waterproof material the yarn
for the weft, or both the warp and weft if desirable, previous to weaving the
fabric; after such coating the yarn may require to be passed through a powder of
farina, chalk or other suitable substance to facilitate the weaving of such water-
proofed yarn. The warp might be coated with waterproofing material by passing
through a solution of rubber when in the loom.
After it is woven the fabric is passed through hot calendar rollers, and the heat
and pressure cause the rubber to soften and fill the interstices, between the warp
and weft, even if the warp yarn only is coated with a solution of rubber, or other
waterproof material.
By this Invention I am enabled to obtain a waterproof cloth without the
appearance of ordinary waterproofed cloth and of less weight.

I ISIDOR FRANKENBURG, of 88 Greengate, Salford in the County of Lancaster,
India-rubber Manufacturer, do hereby declare the nature of said Invention for
IMPROVEMENTS IN THE MANUFACTURE OF WATERPROOF CLOTH, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of my Invention is to make a waterproof cloth that is stronger and
lighter than the common waterproof cloth and will have the appearance of ordinary
cloth.
In performing my Invention I coat the yarn for the warp with a solution of
india-rubber or other waterproof material or I coat with waterproof material the
yarn for the weft or both the warp and weft, if desirable, previous to weaving
the fabric: after such coating the yarn may require to be passed through a powder
of farina, chalk, or other suitable substance to facilitate the weaving of such
waterproofed yarn by removing the stickiness of the coating.
The warp might be coated with waterproofing material by passing through a
solution of rubber when in the loom.
After it is woven the fabric is passed through hot calender rollers and the heat
and pressure cause the rubber to soften and fill the interstices between the warp
and weft, even if the warp yarn only is coated with a solution of rubber or other
waterproof material.
By this Invention I am enabled to obtain a waterproof cloth without the
appearance of ordinary waterproofed cloth and of increased durability as the
waterproofing solution strengthens the yarn.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed
I declare that what I claim is-
The manufacture of waterproof cloth from warp and weft either or both of which
has been. coated with a solution of india-rubber or other waterproof material.
