VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Mechanical Draughtsman, 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 Nineteenth day of November, in the fourteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Alfred Vincent Newton, Her especial license, full power, sole privilege
and authority, that I, the said Alfred Vincent Newton, my exors, admors, and
assigns, and such others as I, the said Alfred Vincent Newton, 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 mentioned, should and
lawfully might make, use, exercise, and vend, within England, Wales, and the
Town of Berwick-upon-Tweed, and in all Her Majesty's Colonies and
Plantations abroad, and in the Islands of Jersey; Guernsey, Alderney, Sark,.
and Man, an Invention of "AN IMPROVED COMPOSITION APPLICABLE TO
COATING OF WOOD, METALS, PLASTER, AND OTHER SUBSTANCES WHICH ARE REQUIRED
TO BE PRESERVED FROM DECAY, WHICH COMPOSITION MAY BE ALSO EMPLOYED AS A
PIGMENT OR PAINT," being a communication from abroad; in which said
Letters Patent is contained a proviso. obliging me, the said Alfred Vincent

page_text: Newton, by an instrument in writing under my hand and seal, particularly to
describe and ascertain the nature of the said Invention, and in what manner
the same is to be performed, and to cause the same to be enrolled in Her
Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in and
by the same, reference being thereunto had, will more fully and at large
appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Alfred Vincent Newton, do hereby declare that the nature of the said Inven-
tion, and the manner in which the same is to be performed, is particularly
described and ascertained in and by the following description thereof (that
is to say)
The object of this Invention, as communicated to me by my Foreign
Correspondent, is to prepare a chemical composition suitable for coating wood,
metals, plaster, and other like substances, and preserving them from decay.
For this purpose a mixture containing the following materials may be prepared
either by the employment of natural products, or of suitable metallurgical
refuse, the proportions given below having been found to be advantageous in
practice:-

page_text: ings of all kinds, ships, stockades, piers, jetties, sleepers for railways, turnpike
and other gates, bridges, and other large works of public utility. When stone
walls, plaster, or cement are to be operated upon, they must first be well
scraped, and freed from all previous paint, and well soaked with a mixture of
one part of sulphuric acid at sixty-six degrees to five parts of water. This
liquor must be applied until effervescence ceases. The surface is then left to dry,
and three coats of the composition are to be laid on, care being taken to let
each coat dry before applying the next coat. In cases where the surface is
very damp, or impregnated with saltpetre, it will be found advantageous to
add to the composition above mentioned from eight to ten per cent. of proto-
sulphuret of antimony.
The foregoing being the base of the Invention for which I obtained Her
Majesty's Letters Patent, I proceed to give the following formulæ, which are
modifications of the improved composition, and are the result of numerous
experiments recently carried on by the Inventor.

page_text: The substances forming these combinations must be ground down, and
diluted with the proportions of oil and essence of turpentine above mentioned.
In certain cases it may be advisable to employ the following coating or mastic,
in order to fill up joints, holes, or flaws, &c., or it may be used to coat the
entire surface to a thickness from one thirtieth to one third of an inch
in depth-

page_text: These substances are to be reduced to a fine powder, well mixed, and
ground to a suitable consistence in a mixture of three parts of linseed oil, and
one part of hempseed oil.
Having now described the Invention as communicated to me by my
Foreign Correspondent, I wish it to be understood that I claim under the
above in part recited Letters Patent,-
First, the manufacture of the composition above described under any and all
its modifications, and its application as a pigment, or as a coating to preserve
wood, metals, plaster, and other substances from decay.
And particularly I claim the use in such composition of silica or silicic acid,
or of silica in some one or more of its combinations, the presence of which
substance is an essential element in the improved composition.
And further, I claim the use of proto-sulphuret of antimony in the manner
and for the purpose above explained.
In witness whereof, I, the said Alfred Vincent Newton, have hereunto
set my hand and seal, this Nineteenth day of May, in the year of our
Lord One thousand eight hundred and fifty-one.
(L.S.) A. V. NEWTON.
AND BE IT REMEMBERED, that on the Nineteenth day of May, in the
year of our Lord 1851, the aforesaid Alfred Vincent Newton 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 Nineteenth day of May, in the year of our Lord One
thousand eight hundred and fifty-one.
