IMPROVEMENTS IN THE MANUFACTURE OF ORNAMENTAL WALL COVERINGS, LEATHER CLOTH, FLOOR CLOTH AND THE LIKE, AND IN COMPOSITIONS USED THEREIN
Year: 1884

page_text: I SIEGISMUND LOEWENTHAL 85 Shakespeare Road, Acton, Middlesex, Manufac-
turer, do hereby declare the nature of my said invention for "IMPROVEMENTS IN
THE MANUFACTURE OF ORNAMENTAL WALL COVERINGS, LEATHER CLOTH, FLOOR
CLOTH AND THE LIKE, AND IN COMPOSITIONS USED THEREIN," to be as follows:-
The object of this invention is to compound certain ingredients together to form
a plastic adhesive body capable of being spread or rolled upon a canvas or other
backing to any desired thickness and which can be printed in plain or many colors
or metalized to produce ornamental or decorative effects either plain or embossed
and with or without an exterior or surface sheet of canvas according to the use the
material so prepared is intended for.
The material is particularly adapted for wall decoration, immitation leather, floor
cloth and other useful purposes.
For this purpose I employ a composition of which African Flake is the chief
ingredient. I spread this composition upon a fabric, paper or card board and after
a pattern is printed on its surface by means of blocks, rollers or any other known
process, I cause the material to be embossed by means of a die and pressure or
rollers on the surface of which a design is engraved. The material after this is.
hung in a heated room for a considerable period in order to get dry.
°
The compound is composed of 100 lbs. of African Flake, 10 lbs. of Rubber,
100 lbs. of Rubber substitute, 10 lbs. of Ozokerit, 1 cwt. of Infusoria and 1 cwt. of
wood pulp, or ground cork, add to this 2% of sulphuric acid and 5 % Muriatic
Acid All these materials in their various proportions I mix in a mixing machine
and after amalgamating them thoroughly I spread the compound on fabric, paper
or cardboard by means of a calender to a suitable thickness. In some cases
I spread a very light fabric on the surface of the compound.
This can be printed in the same manner as wallpapers are generally printed and
when the colors are thoroughly dry I bring the whole under a press on the top
platten of which an engraved die is secured corresponding with the pattern printed

by means of the pressure caused by the press I emboss the printed pattern on the
material.
In these two cases I also change the proportion of the ingredients given above.
On floor cloth I omit the latter process on leather cloth I emboss the material
either with or without the printed pattern which is also the case with wall
decorations when desirable.
After this process is completed I expose the material to a heat of from 80 to
100 degrees Fahrenheit.

facturer, do hereby declare the nature of my said invention for "IMPROVEMENTS IN
THE MANUFACTURE OF ORNAMENTAL WALL COVERINGS, LEATHER CLOTH, FLOOR
CLOTH AND THE LIKE, AND IN COMPOSITIONS USED THEREIN," 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 this invention is to compound certain ingredients together to form
a plastic adhesive body capable of being spread or rolled upon a canvas or other
backing to any desired thickness,and which can be printed in plain or many colors
or metallized to produce ornamental or decorative effects either plain or embossed
and with or without an exterior or surface sheet of canvas according to the use the
material so prepared is intended for.
The material is particularly adapted for wall decorations, imitation leather, floor
cloth, and other useful purposes. For this purpose I employ a composition of
which African Flake is the chief ingredient. I spread this composition upon a
fabric, paper, or card board and after a pattern is printed on its surface by means
of blocks, rollers or any other known process I cause the material to be embossed
by means of a die and pressure or rollers on the surface of which a design is
engraved. The material is after this hung in a heated room for a considerable
period in order to get dry.
The compound is composed of 100 pounds of African Flake, 10 pounds of
rubber, 100 pounds of rubber substitute, 10 pounds of ozokerit, 1 hundred weight
(cwt) of Infusoria, 1 hundred weight (cwt) of wood pulp or ground cork, add to
this 2% of sulphuric acid and 5% muriatic acid. All these materials in their
various proportions I mix in a mixing machine and after amalgamating them
thoroughly I spread the compound on fabric, paper, or card board by means of a
calender to a suitable thickness. In some cases I spread a very light fabric on the
surface of the compound.
This can be printed in the same manner as wall papers are generally printed and
when the colors are thoroughly dry I bring the whole under a press on the top
platten of which an engraved die is secured corresponding with the pattern printed
on the surface of the material I place the printed pattern direct under the die and
by means of the pressure caused by the press I emboss the printed pattern on the
material. Qn floor cloth I omit the latter process; on leather cloth I emboss the
material either with or without the printed pattern which is also the case with
wall decorations when desirable.
After this process is completed I expose the material to a heat of from 80 to
180 degrees Fahrenheit.

page_text: 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 admixture of the within named ingredients in or about the proportions
stated for the manufacture of ornamental wall coverings, leather cloth, floor cloth
and the like.
