A NEW OR IMPROVED BUOYANT FABRIC
Year: 1884

page_text: PROVISIONAL SPECIFICATION:
I WILLIAM JACKSON of 106 Denbigh Street in the County of Middlesex,
Manufacturer, do hereby declare the nature of said invention for A NEW OR
IMPROVED BUOYANT FABRIC, to be as follows:-
The improvements relate to new or improved fabrics made buoyant by the use
of cork in combination with wool, worsted, cotton, silk, or two or more of such
materials and the invention consists in the employment and arrangement of such
combinations in such manner that a material shall be formed which may serve for
garments or linings to same, or for sheets, sails & or for other purposes where
capability of floating in water is desired.
The invention is performed by cutting cork into strips, and weaving or knitting
such strips with wool, worsted, cotton, hemp, silk or other textile material; the
cork being preferably made the warp, although it may in some cases be made the
woof, and to render such cork stronger for weaving or knitting I prefer to twist it
into a strand with one or more threads of wool, worsted, cotton, hemp or silk.

I, WILLIAM JACKSON of 106 Denbigh Street in the County of Middlesex,
Manufacturer, do hereby declare the nature of my invention for A NEW OR
IMPROVED BUOYANT FABRIC, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :–
The improvements relate to new or improved fabrics made buoyant by the use
of cork, in combination with wool, worsted, cotton, hemp, silk; or two or more of
such materials and the invention consists in the employment and arrangement of
such combinations in such manner that a material shall be formed which inay
serve for garments or linings to samo, or for sheots, sails & or for other purposes
where capability of floating in water is desired.
The invention is performed by cutting cork into strips or threads as after
described and weaving or knitting such strips or threads of cork with wool, worsted,
cotton, hemp silk or other textile material in the usual manner, the cork being
preferably made the warp, although it may in some enses be made the woof. To
render such cork stronger & fit for weaving or knitting I twist it into a strand
with one or more threads of wool, worsted, cotton, homp or silk; or the cork is
first cut into very thin sheets each sheet then sized over with a layer of adhesive
Bolution, the sheets thus prepared are joined together in as many layers as may be
necessary according to the thickness of the thread required the sheets thus
prepared are then hammered and rolled in order to weld together the different
layers and to give pliability and elasticity, and to remove the grit woody and hard
substances in the cork, when this is effected the sheets are then placed in a drying
room for the purpose of drying-when sufficiently dry the sheets are then ready
for cutting into the threads In some casca one or more layers of fine textile
material may be interposed between tlie cork-sheets; or put on outside, só as to
give tensile strength to the thread.
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 new or improved buoyant fabric made by weaving or knitting strips or
threads of cork with textile materials substantially as and for the purposes herein
described and set forth.
