Year: 1846

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HAROLD
CREASE, of Brixton Hill, in the County of Surrey, Paper Stainer, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-third day of July, in the tenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Harold Crease, my exors, adñors, and assigns, Her especial licence, full power,
sole privilege and-authority, that I, the said Harold Crease, my exors, admors,
or assigns, or such others as I, the said Harold Crease, my exors, admors, or
assigns, should at any time agree with, and no others, from time to time and
at all times during the term of years therein expressed, should and lawfully
might make, use, exercise, and vend, within England, Wales, and the Town
of Berwick-upon-Tweed, and in the Islands of Jersey, Guernsey, Alderney,
Sark and Man, and also in all Her said Majesty's Colonies and Plantations
abroad, my Invention of "CERTAIN IMPROVEMENTS IN THE PREPARATION OF
PAINTS AND COLORS FOR DECORATIVE AND OTHER SIMILAR PURPOSES;" in which
said Letters Patent is contained a proviso, that I, the said Harold Crease,
shall cause a particular description of the nature of the said Invention, and in
what manner the same is to be performed, to be enrolled in Her said Majesty's
High Court of Chancery within six calendar months next and immediately

page_text: after the date of the said Letters Patent, as in and by the same, reference
thereunto being had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Harold Crease, do hereby declare that the nature of my Invention, and the
manner in which the same is to be performed, is particularly described and
ascertained in and by the following instrument in writing, that is to say :-
My Invention relates to the preparation of paints and colors to be used for
decorative and other purposes, which, when prepared according to my
improvement, may be used and applied in a similar way to that description
of painting which is known in the trade by the name of flatting or dead white 1
drying equally firm, and will be extremely free from any unpleasant and
soffensive smell.
These improvements consist in the combination of shell-lac, gelatine,
animal or vegetable oil, with an alkaline base. To effect these improvements
I add and amalgamate this combination to ordinary pigments, by which
process I produce a paint, which without any other addition, becomes dry
and capable of receiving a second coat within one hour. I will now describe
the means I have found the best for the manufacture of the improved paint,
and the proportionate quantity of the different ingredients to be hereafter
named. I prefer to use the proportions as follows:―
I take two and a half pounds of well bleached shell-lac, to which I add
half a pound of borax, or any other suitable alkaline base (but I prefer borax);
I then add to these two ingredients about five quarts of water, and then boil
or simmer till the whole is dissolved, and then I continue the boiling or
simmering till the solution is reduced in bulk to about one gallon. To one
quart of this solution, prepared in the manner I have above described, I add
from half a pint to one pint of pure gelatine, according to its strength, and
four drachms of alcohol.. I allow this mixture to get well dissolved, and
incorporated by degrees by subjecting it to a slight elevation of temperature.
I then mix this last mixture, containing the gelatine, with the remaining
portion of the solution before described, composed of well bleached shell-lac,
borax, and water, with the necessary quantity of white lead to give it a body,
and a small quantity of well bleached oil, in the proportion of seven pounds of
white lead and two ounces of well bleached oil to one quart of the solution,
The whole is afterwards put in a suitable paint mill, well ground and tritu-
rated as in the ordinary manner, and afterwards thinned with a solution of
shell-lac, when it will be ready for use. The paint may be thinned according
to the nature of the work about to be painted over, by adding to it the

page_text: solution of shell-lac in a sufficient proportion, according to the judgment of
the workman.
I must here observe that my preparation is applicable to all paints,
pigments, and colors necessary to artists and painters, with the exception of a
few pigments which are impregnated with iron, in combination with all other
substances as a base.
Having now described the nature of my Invention, and the best method
known to me at present for carrying the same into operation, I wish it to be
understood that what I claim is the mixing, combination, and use of the
different ingredients in the proportions and quantities (or as near as may be)
herein-before described, by which I am enabled to manufacture a paint which
is free from offensive smell, and which will be sufficiently dry within one hour
to admit of another coat being laid on.
In witness whereof, I, the said Harold Crease, have hereunto set my
hand and seal, this Twenty-third day of January, in the year of our
HAROLD (L.B.) CREASE.
AND BE IT REMEMBERED, that on the Twenty-third day of January,
in the year of our Lord 1847, the aforesaid Harold Crease came before our
said Lady the Queen in Her Chancery, and acknowledged the Specification
aforesaid, and all and every thing therein contained and specified, in form
above written. And also the Specification aforesaid was stamped according
to the tenor of the Statute made for that purpose.
Enrolled the Twenty-third day of January, in the year of our Lord One
thousand eight hundred and forty-seven.
