Place. Vauxhall, and ABRAHAM
WILLIAM KIRRAGE, of No. 5. Albion
RIPLEY. of the same Place, in the County of Surrey, do hereby declare the
nature of the said Invention for "THE AMALGAMATION OF CERTAIN MATERIALS
FORMING A PLASTIC COMPOSITION APPLICABLE TO WORKS OF THE FINE ARTS, BUILD-
ING PURPOSES, IMITATIONS OF MARBLES, ANCIENT CARVINGS, AND VARIOUS OTHER
USES," to be as follows:-
This improved plastic material consists of vegetable gluten. gelatine. or
albumen, mixed with a certain proportion of animal gluten. gelatine, or
albumen, and oils or animal fat, with a portion of caoutchouc. sulphate of
lime. gypsum, or other cements, fine river or other sand, pounded glass or
marble, metal filings, red or white lead, and all description of colors to be
added when required for ornamental purposes; the proportions we prefer are,
to four parts by measure of vegetable gluten. gelatine, or albumen, add:
two parts of animal gluten, gelatine, or albumen, boiled to about the
017

page_text: thickness a joiner uses his glue, then add one-sixteenth part of oil or animal
fat, to which add a fortieth part of india-rubber in solution; these materials
must be intimately united, and when at the boiling point (or nearly so)
mix in the metal filings, pounded glass, or pounded marble, according to
the purposes required, then add as much sulphate of lime, gypsum. or other
cements as will make it into a stiff paste; to this may now be added various
colors, and then rolled or moulded into any form required, it will be plastic when
wet. and extremely hard when dry, it will take a polish in about twenty-four
hours from the time of moulding.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Kirrage and Abraham Ripley in the Great Scal
Patent Office on the 28th February 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
KIRRAGE, of No. 5, Albion Place, Vauxhall, and ABRAHAM RIPLEY, of the
same Place, in the County of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of August, in the year of our Lord
One thousand eight hundred and sixty. in the twenty-third year of Her
reign, did. for Herself. Her heirs and successors. given and grant unto us.
the said William Kirrage and Abraham Ripley, Her special licence that wc,
the said William Kirrage and Abraham Ripley, our executors, administrators.
and assigns, or such others as we, the said William Kirrage and Abraham
Ripley, our executors, administrators, and assigns, should at any time agree
with, and no others. from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make. usc. exercisc.
and vend. within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "THE AMALGAMATION OF
CERTAIN MATERIALS FORMING A PLASTIC COMPOSITION APPLICABLE TO WORKS OF THE
FINE ARTS, BUILDING PURPOSES, IMITATIONS OF MARBLES, ANCIENT CARVINGS, AND
VARIOUS OTHER USES," upon the condition (amongst others) that we, the said
William Kirrage and Abraham Ripley, our executors or administrators, by an
instrument in writing under our, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same
.to be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent,

page_text: NOW KNOW YE, that we, the said William Kirrage and Abraham Ripley,
do hereby declare the nature of our said 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):-
We claim the amalgamation of animal and vegetable gelatines, glutens, or
albumens with a portion of caoutchouc, oils, or animal fats in a liquid state. to
mix with sulphate of lime. gypsum, china clay. French chalk. or other cements.
to form a plastic material capable of being moulded or rolled to any required
form or shape. We prefer, for ornamental purposes, the proportions named
in our Provisional Specification, but in all cases we prefer mineral colours.
In the case of a pure white being required to represent statuary marble, we
propose to leave out the use of all oils, fat. or animal matters. substituting a
vegetable gluten made of rice. arrowroot, wheaten flour, or such other albumens
as will not discolour the cements which in this case may consist of Parian.
Keen's. Martin's. or of prepared fine plaster of Paris. mixed with china clay
or French chalk. These cements can be used separately or mixed as they may
be required for various purposes, which is no novelty. being in use and well
known; but the novelty of our Invention. and that which we particularly claim
is. the amalgamation of vegetable and animal glutens. gelatines, or albumens,
as a liquid bind. and the amalgamation of any of the known cements with
china clay or French chalk, to form the same into a plastic material. This
material will polish very readily, and retain the same in any climate. and the
cost will be much less than half the price of marble, porphyry. granite, or any
other expensive stones used in the fine arts, and for other purposes.
In witness whereof, 1. the said William Kirrage, have hereunto set my
hand and seal. on behalf of myself and the said Abraham Ripley, this
Twenty-sixth day of February, in the year of our Lord One thousand
eight hundred and sixty-one.
WILLIAM KIRRAGE. (L.S.)
