page_text: PROVISIONAL SPECIFICATION left by William Robert Lake at the
Office of the Commissioners of Patents, with his Petition, on the
5th March 1878.-A communication from abroad by Frederick
Beck, of the City and State of New York, United States of
America, Manufacturer.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
Patent Agents, Southampton Buildings, London, do hereby declare
the nature of the said Invention for "AN IMPROVED MANUFACTURE OF
COLOURED OR ORNAMENTED PAPER, CLOTH, AND OTHER SIMILAR MATERIALS, AND
PROCESSES AND COMPOUNDS EMPLOYED THEREFOB,' a communication, to be
as follows:-
"
This Invention is applicable to the colouring or ornamentation of paper,
cloth, and other fabrics or materials for wall hangings, coverings of fancy
boxes, window shades, and a great variety of useful and ornamental
purposes.

page_text: The said Invention consists in coating paper, cloth, wood, metals, and
other materials with mica scales reduced to a powder, by first printing
on the surface of such materials or coating the same with an adhesive
substance and then spreading the mica thereon by means of sieves or
otherwise; also in a fabric such as paper cloth or the like coated with i
mica scales by first coating the surface of such fabric or printing
thercon with an adhesive material and then spreading over it mica soales
in a powdered state by means of sieves or otherwise; further in a com-
pound consisting of disintegrated mica with transparent or translucent
adhesive substances for the purpose of coating paper, cloth, or other 1
fabrics or materials; also in a compound consisting of mica scales,
transparent or translucent adhesive substances and glycerine for coating
paper, cloth, or other fabrics or materials.
In carrying this Invention into practice I take mica scales and reduce
them to a powdered state, and then coat the surface of the paper, cloth, :
or other material to be ornamented with a solution of starch or glue or
other adhesive substance, and spread thereon before it has become dry
the powdered mica by means of sieves or otherwise; or I print on the
surface to be ornamented a solution of glue or other adhesive substance,
and spread thereon the powdered mica, the surplus mica being
removed by means of brushes or otherwise, after the adhesive compound
has set.
Instead of coating the material to be ornamented or printing thereon
first an adhesive substance and then spreading thereon the powdered
mica, I prepare a compound of finely reduced mica scales with solutions
of starch, glue, gum, or other suitable transparent or translucent
adhesive substance or substances, to which I sometimes add glycerine
for the purpose of imparting suppleness to the compound when dry, I
then select any suitablo paper, cloth, or other fabric or material, and
coat its surface with the compound by the use of brushes or other
suitable means. The compound of mica scales and adhesive substances
should be made of such a consistency as to flow freely under the
brush.
A
I can thin modo as follows. T tako cie

page_text: gallon of water, I then take fifty pounds of finely reduced mica scales
and mix them with water and then add them to the solution of starch
and glue, after which I add ten pounds of glycerine, and lastly add
water enough to make the compound measure forty-five gallons; after
3 a thorough mixing of the compound I apply it to the fabric in the
manner described.
