PROVISIONAL SPECIFICATION. ·
Improvements in the Manufacture of Linoleum and similar
Floorcloth Preparations.
I ARCHIBALD CAMPBELL Thornton Fifeshire, Chemist, do hereby declare the
nature of this invention to be as follows :-
:-
Linoleum and other similar floorcloth preparations have up to the present been
essentially a mixture of ground cork and boiled or oxidized linseed oil. Since the
origin of this industry the price of the waste cork used therein has advanced
considerably, and I now propose to use as a substitute for cork either wholly or in
part, dried peat, turf, or other similarly preserved vegetable matter, preferring
however that specially prepared variety known as "moss litter," now so largely
used as an absorbent in stables, cowhouses &c. When thoroughly dried it is readily
ground into a powder, which resembles cork powder closely, both as regards
lightness and elasticity, and is therefore specially suited as a substitute for it. The
moss litter
or other dried peaty material is ground into a suitable degree of
fineness by similar appliances to those used for cork, and the subsequent treatment
for conversion into linoleum or other floorcloth is in all respects practically identical
with that pursued in the case of cork.

Improvements in the Manufacture of Linoleum and similar
Floorcloth Preparations.
I ARCHIBALD CAMPBELL of Thornton in the County of Fife, Manufacturing
Chemist 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 :-
Linoleum and other similar floorcloth preparations have up to the present been
essentially a mixture of ground cork with boiled or oxidized linseed oil. Since the
origin of this industry the price of the waste cork used therein has advanced
considerably, and I now propose to use as a substitute for cork either wholly or in

When thoroughly dried, it is readily ground into a powder which resembles
cork powder, both as regards lightness and elasticity, and is therefore specially
suited as a substitute for it. The "moss litter" or other dried peaty material is
ground into a suitable degree of fineness by similar appliances to those used for
cork, and the subsequent treatment for conversion into linoleum or other floorcloth
is in all respects practically identical with that pursued in the case of cork.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :-
1. The substitution either wholly or in part of dried and ground peat, turf, "moss
litter" or other similar material, for cork in the manufacture of linoleum and other
floorcloth preparations.
