I, THOMAS SKINNER, Gentleman, 26, Dalton Terrace, Gell Street,
Sheffield, in the County of York, do hereby declare the nature of the
said Invention for "AN IMPROVEMENT FOR ETCHING ON GLASS," to be as
follows:-
My Invention consists in the application or use of flexible moulds or
blocks for pointing or producing designs on glass. These blocks or
O moulds are composed of certain proportions ofglue & common treacle,
or india-rubber, or gutta percha, or any other suitable material, & are
made from types or designs cut in wood or metals, as described & set

blocks, is subjected to the action of the well-known processes of biting
& deadening through the action of fluoric acid, or the vapour of
similar agents, or the action of the sand blast.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Skinner in the Great Seal Patent Office
on the 17th September 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS

page_text: NOW KNOW YE, that I, the said Thomas Skinner, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement in writing, that is to say:-
This Invention relates to an improvement in the process or method of
etching on glass.
The improved process consists in the application and use of flexible
moulds or blocks in etching or printing or producing designs on glass.
The blocks or moulds are composed of certain proportions of glue
and common treacle, say. 2 lbs. of treacle and 1lb. of glue, with
a small quantity of Venetian red to give it solidity and firmness, or of
india-rubber or gutta percha, or any other suitable material, and they
are made from type or from designs cut in wood or metals, as described
and set forth in the Specification of the Letters Patent granted to me,
dated the 4th day of May, 1874, No. 1570.
The glass after receiving the impressions from the flexible moulds or
blocks as intended is subjected to the well-known process of biting and
deadening through the action of fluoric acid, or with or by the vapour
of similar agents, or by the action of the sand blast.
Having now described the nature and object of my said Invention,
together with the manner in which the same is to be or may be per-
formed or carried into practical effect, I would remark in conclusion that
I claim as my Invention, the application and use of flexible moulds or
blocks, substantially as herein described for the purpose of producing
etchings and ornamental designs on glass in a more perfect manner
than hitherto.
In witness whereof, I, the said Thomas Skinner, have hereunto set
my hand and seal, this Fifteenth day of September, in the year
of our Lord One thousand eight hundred and seventy-five.
