PROVISIONAL SPECIFICATION.
Process for Manufacturing a Material for Covering Walls and
Floors.
I, HERMANN BROCKHUES Manufacturer at Oberwalluf in the Province of Rhineland
and Kingdom of Prussia do hereby declare the nature of this invention to be as
follows:-
Leather and refuse of leather is finely ground, either in a ran state or after being
roasted to charcoal, and mixed up-if desired with an addition of glutinous and
resinous materials such as shellac, resin gutterpercha, adragant and the like to a
thick pap, and this pap spread in such a manner on a firm coarse textile fabric which
serves as a frame-work, that the latter is not seen from the outside. The whole is
then rolled or pressed to make it impervious. On the outside the stuff may then
be given a coating of coloured varnish, either in one colour or in patterns.
The material may also be coated with mineral colours, etc.
Thus a substance is obtained similar to the well-known linoleum, but offering
much more resistance to wear from the feet and other mechanical wear and tear,
absolutely non-inflammable and resisting the attacks of water and vapours.
Dated this 24th day of November 1896.

Process for Manufacturing a Material for Covering Walls and
Floors.
I, HERMANN BROCKHUES, Chemist of Oberwalluf in the Province of Rhineland and
Kingdom of Prussia 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 :-
Leather and refuse of leather is finely ground after being roasted to charcoal and
mixed up to a thick pap with oxidised linseed oil and if desired with an addition of
agglutinants and resinous materials such as shellac, colophony, gutta percha,
adragant and the like, and, if desired, with mineral colours and the like to a thick
pap.
In carrying out my invention there may be used all the various materials and in
all the proportions which as they are useil uptoday in the manufacture of linoleum,
but in each case the usual ordinary cork-flour is remplaced by the finely grounded
leather charcoal. The quantity of the latter varyes with the nature and weight of
colour used; if for instance a light colour, such as burnt black is used, for the same

page_text: quantity of colour a smaller quantity of charcoal is necessary, than if the colour is
heavy such as zinc-white and the like.
The above mentioned thick pap, obtained by any suitable process and by any
suitable mixing of materials, is then spread in such a manner on a firm coarse
textile fabric which serves as a frame-work, that the latter is not seen from the outside.
The whole is then rolled or pressed to make it impervious.
On the outside the stuff may be given a coating of coloured varnish, either in one
colour or in patterns.
Thus a substance is obtained similar to the well-known linoleum, but offering
much more resistance to wear from the feet and other mechanical wear and tear,
absolutely non-inflammable and resisting the attacks of water and vapours.
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 use of leather charcoal in a finely ground state instead of the ordinary cork-
flour, mixed with oxidized linseed oil for producing a substance similar to linoleum.
Dated this 20th day of August 1897.
