Improvements in Compositions or Coatings for the Manufacture of
Carriage and other Covers, Imitation Leather, Wall Decoration,
Book Covers, and the like.
I, THOMAS THOMSON, of Fereneze, Barrhead, in the County of Renfrew, North
Britain, Chemist, do hereby declare the nature of this Invention to be as follows,
that is to say:—
My said Invention has for its object the making of improved compositions or
coatings which may be advantageously used in the manufacture of carriage and other
covers, imitation leather, wall decoration, book covers and the like. My improved
compositions are of a flexible character and are not liable to deteriorate.
My Invention consists in employing as a principle ingredient of the compositions
certain resinous residues of a semisolid character obtained in distilling or refining
various oils and fatty acids, or in the treatment of oils for the separation and purifi-
cation of stearic, margaric, palmitic, oleic, and similar acids. I combine the resinous
residue with chalk or other suitable inert earth, and with cotton-seed, rape, or other
suitable vegetable oil, together with a proportion of caddis, or lint, or other suitable
fibrous material, also oxide of lead or other drier, and any suitable coloring matter.
The materials are intimately mixed together in a kneading or mixing machine, with
the aid of heat, and whilst hot the composition is spread on a web or on any suitable
surface by means of rollers in a manner usually practised with such materials, or it
may be pressed into moulds.
The proportions of the ingredients may be varied to suit particular applications,
but for general purposes a good composition is obtained by combining 16 parts by
weight of resinous residue with 12 of chalk or inert earth, 8 of rape oil, 8 of coloring
matter, 4 of caddis, and 2 of lead oxide.

1, THOMAS THOMSON of Fereneze, Barrhead, in the County of Renfrew, North
Britain, 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, that is to say :-
My said Invention has for its object the making of improved compositions or
coatings which may be advantageously used in the manufacture of carriage and other
covers, imitation leather, wall decoration, book covers, and the like. My improved
compositions are of a more or less flexible character, and are not liable to deteriorate.
My Invention consists in employing as a principal ingredient of the compositions
certain resinous residues of a semisolid character obtained in distilling or refining
various oils and fatty acids, or in the treatment of oils for the separation and puri-
fication of stearic, margaric, palmitic, oleic, and similar acids. I combine the resinous
residue with chalk or other suitable inert earth, and with cotton seed, rape, or other
suitable vegetable oil, together with a proportion of caddis, or lint, or other suitable
fibrous material, also oxide of lead, or other drier, and any suitable coloring matter.
In practically carrying out my Invention the materials are intimately mixed
together in a kneading or mixing machine, with the aid of heat, such as can be
imparted by means of steam of about atmospheric pressure in a jacket space with
which the mixing vessel is provided. Whilst hot the composition is spread on a web
or on any suitable surface, by means of rollers, in a manner usually practised with
such materials; or it may be pressed into moulds.
The composition is finally aged or dried by exposure to air, the action being
quickened by a moderate heat, namely about 80 degrees, Fahrenheit.
The proportions of the ingredients may be varied to suit particular applications ;
but for general purposes, a good composition is obtained by combining 16 parts, by
weight, of resinous residue, with 12 of chalk or inert earth, 8 of rape oil, 8 of coloring
matter, 4 of caddis, and 2 of lead oxide. This composition may be rendered less
flexible by increasing the proportion of lead oxide; and on the other hand a more
flexible composition may be made with the ingredients in the following proportions;
namely, 16 parts resinous residue, 8 dry clay, 10 rape or other vegetable oil, 4 coloring
matter, 4 caddis, and 1 lead oxide.
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 :-
Making improved compositions or coatings with the ingredients, in the manner,
and for the purposes substantially as hereinbefore described, a principal ingredient
being resinous residues of the kind specified.
