WE, THOMAS CONN, of The Caxton Works, Bristol, Foreman, Gelatine and
Showcard Mounter, and MARDON, SON & HALL LIMITED, of The Caxton Works,
Bristol, Printers, do hereby declare the nature of this invention to be as follows:-
This invention relates to the production of a pliable material in imitation of
leather, cloth, parchment, or the like and is designed for use in bookbinding, printing,
stationery, and other industries in which such material may be used.
In carrying the invention into effect we take in proportionate parts gelatine, white
or colored enamel pulp, white shellac, glycerine, methylated spirit, formaldehyde and
castor oil, and cause the mixture thus composed to flow in a liquid state on to plates
or sheets of glass or metal, and while it is still liquid a sheet of linen, cotton or other
fabric is immersed in the mixture on the plates so that it may become incorporated
therewith.
The whole is then placed in a heated room to dry and when dry the sheets are cut
away from the plates to receive a gloss or a dull surface, or to be ornamented as may
be desired.

Imitation Leather, Cloth, Parchment, and the
We, THOMAS CONN, of The Caxton Works, Bristol, Foreman, Gelatine and
Showcard Mounter, and MARDON, SON & HALL LIMITED, of The Caxton Works,
Bristol, Printers, 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 :-
This invention relates to the production of a pliable material in imitation of
leather, cloth, parchment, or the like, and is designed for use in book binding,
printing, stationery, and other industries in which such material may be used.
The material is composed of gelatine, glue, or the like, enamel pulp, either white
or colored, as desired, with glycerine and formaldehyde, which compound is placed on
plates of suitable material which may be plain, or upon which may have been etched
or otherwise produced a pattern or design, and whilst still in a liquid state a backing
of suitable material is caused to adhere thereto to strengthen the material. The
whole is then dried by heat in a suitable chamber and when dried the material is
removed from the plates and the surface polished and varnished.

page_text: In carrying the invention into effect we take 24 pounds of isinglass, gelatine, glue,
gum, or other similar substance and dissolve it in about four gallons of water, adding
to this six pounds, or thereabouts, of white or other enamel pulp, one pound of
glycerine, six ounces white shellac, four ounces methylated spirit, one ounce castor
oil and six ounces of formaldehyde (sometimes known as formaline). To this is added
the necessary dye or coloring matter to give the material the requisite color or tint
required. The whole of the above constituents are melted together and whilst it is
still in a liquid state caused to flow on to metal, glass or other plates, the surfaces of
which may be either left plain or may have engraved or otherwise produced upon
then the design or pattern required to be produced upon the surface of the material.
Whilst upon the plates above referred to, and when still liquid, a sheet of linen or
cotton fabric or other material is placed upon the exposed surface of the material, and
sufficient pressure applied thereto, by any suitable means, to cause the said linen or
the like to adhere thereto and form a backing for strengthening the material. When
set and dry the material is removed from the plates and the embossed surface polished
and varnished with any suitable flexible varnish, which may, if desired, be waterproof.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
The material for use as a substitute for leather, parchment, or other inaterials, or
otherwise, composed of the materials herein set forth and produced in a manner
snbstantially as herein described.
