PROVISIONAL SPECIFICATION.
Improvements in Colouring Cork used in the Manufacture of Floor
Coverings, and in Apparatus used in Colouring the same.
I WALTER WARD of West End Dye Works Halifax in the County of York
Dyer do hereby declare the nature of this invention to be as follows:-
Hitherto the cork used in the manufacture of floor coverings has been colored
by the use of paints or pigments which do not penetrate through the whole of
the cork.
I now dye the cork various colors required, such dyes penetrating more
thoroughly through the cork, thus obtaining more solid and durable colors than
hitherto
The cork to be dyed is placed in a boiling pan or cistern, in which is an agitator
to draw the cork under the surface of the liquid, the dyes used being anilines, and
derivatives therefrom, also vegetable, or other suitable dyes. Or the said dyes
may be applied to the cork when mixing with the other ingredients used in the
manufacture of the said floor coverings.

COMPLETE SPECIFICATION.
Improvements in Colouring Cork used in the Manufacture of Floor
Coverings, and in Apparatus used in Colouring the same.
I, WALTER WARD of West End Dye Works, Halifax in the County of York,
Dyer, do hereby declare the nature of this invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
Hitherto the cork used in the manufacture of floor coverings has been coloured
by the use of paints or pigments which does not penetrate through the whole of
the cork, consequently the colours of the linoleum or other floor covering are
not solid.
I now dye the cork various colours required, such dye penetrating more
thoroughly through the cork, thus obtaining more solid and durable colours than
hitherto.
The cork to be dyed is placed in a boiling pan or cistern, in which is an agitator
to draw the cork under the surface of the liquid, the dyes used being analines, and
dereratives therefrom, also vegetable dyes.
Or the cork may be dyed when mixing with the other ingredients used in the
manufacture of the said floor coverings, by analine colours which are only soluble
in oils or fats.
After the cork is dyed it is run into a sieve-tray, above a suitable tank, into.
which the liquid runs, and from which it is pumped back into the dye pan or
cistern; the sieve-tray is removed and may be placed within a hydro-extractor, to
extract the liquid or moisture therefrom, it may then be dried by any suitable
means.

page_text: A is the boiling pan or cistern, B is the agitator for drawing the cork under the
surface of the liquid, after the cork is dyed, the contents of the pan are run off
into the tank C, upon the top of which is a strainer or sieve-tray D, for collecting
the cork, then the residue dye liquor is lifted back into the boiling pan A. by the
centrifugal or other pump E, thus utilizing the dye to the best advantage.
Fig. 2 shows a deep sieve-tray or cage D, shaped at F, so as to fit into a hydro-
extractor, the tank C being made with an extended flange G around its top, for
preventing the overflow of the liquid from the sieve-tray D, H is the brick wall,
and J the cover for the apparatus.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. Dyeing cork used in the manufacture of linoleum or other floor coverings,
for the purposes described.
2. Treating cork by the method and apparatus shown and described (or their
equivalents), for the purposes set forth.
