TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
RoYDs, of Southampton, in the County of Hants, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of May, in the year of our Lord One
thousand eight hundred and fifty-six, in the nineteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Robert Royds, Her special licence that I, the said Robert Royds, my
executors, administrators, and assigns, or such others as I, the said Robert
Royds, my 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, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "AN IMPROVEMENT OR
IMPROVEMENTS, IN THE MANUFACTURE OF .Soar," upon the condition (amongst
others) that I, the said Robert Royds, my executors, or administrators, by au
instrument in writing under my, 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.
NOW KNOW YE, that I, the said Robert Royds, 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
thereof, that is to say:-
My Invention consists in incorporating with the ingredients ordinarily
employed in the manufacture of soap, gelatine and gelatinous substances; with
or without borax. I proceed as follows:-To the ingredients generally used in
the manufacture of soap, such as tallow, or animal, vegetable; or fish oil,.boiled
in a lye of soda ash, at a strength of from 10° to 30° Beaumé, with or without
resin, or to any other ingredients applicable to the manufacture of soap," and
while they are in a hot state I add from twenty to thirty per cent., more or
less, of gelatine in a liquid state, and at a temperature of about 92° Fahrenheit,
more or less; and stir the mass until the ingredients have become thoroughly
intermixed. Sometimes in addition to the liquid gelatine I stir in from ten to
fifteen per cent. of borax.

page_text: Although I find it preferable to stir in the gelatine to the ingredients while
both are in a heated state, I do not limit myself to operating in such manner,
as some manufacturers might add the gelatine before the other soap-forming
materials were heated.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim, as my improvement
in the manufacture of soap, the incorporating of gelatine with any and all of
the ingredients which have been or may be employed in such manufacture.
In witness whereof, J, the said Robert Royds, have hereunto set my
hand and seal, this Fifth day of November, One thousand eight hundred
and fifty-six.
ROBT ROYDS. (L.B.)
