TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
LOUIS LAMENAUDE, formerly of Passage Jeoffroy, Paris, now of 315, Oxford
Street, in the City of Westminster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent under the Great Seal of the United Kingdom of Great Britain and
Ireland, bearing -date at Westminster, the Eighteenth day of July, in the
twelfth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Jean Louis Lamenaude, Her special licence,
that I, the said Jean Louis Lamenaude, my executors, administrators, and
assigns, or such others as I, the said Jean Louis Lamenaude, my executors,
administrators, and 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, my Invention of "A NEW
PROCESS OF APPLYING OR FIXING LETTERS OF METAL UPON GLASS, MARBLE, WOOD,
AND OTHER SUBSTANCES;" in which said Letters Patent there is contained a
proviso obliging me, the said Jean Louis Lamenaude, by an instrument in

page_text: writing under my hand and seal, particularly to describe and ascertain the
nature of my 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 two calendar months next and immediately after the date of the said
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
Jean Louis Lamenaude, do hereby declare that the nature of my said Inven-
tion, and the manner in which the same is to be performed, are described
and ascertained by the words following, that is to say :-
My Invention consists of a new process of Applying or Fixing Letters of
Metal upon Glass, Crystal, Marble, Stone, Porcelain, Wood, Metal, or other
hard and smooth surfaces, and that the compositions for fastening such letters
on the surfaces of the above-named substances or materials are such as to
resist the action of all changes of the atmosphere, whether in humidity or
temperature, and that such letters when fastened on by such compositions as
are herein named are rendered perfectly firm and immoveable. The object
sought to be attained by this Invention is to secure thin metallic letters on
sinooth surfaces without the use of metallic fastenings, such as rivetting,
bolting, screwing, or by the use of wire in any way. The letters which I
generally use, and which I hereby recommend, are cut out of thin metal, either
of silver, brass, copper, zinc, &c., or if made with either of the simple metals,
or by the electro-galvanic process, or gilded by the electro-galvanic process on
simple sheet metal, or letters having a thin metallic base and an enamelled
surface. These letters I affix on the surfaces of the polished materials herein
named, by means of certain glutinous compositions dissolved or mixed with
various solvents. The proportions which I use in general are as follows:-
1. Copal varnish
15 parts.
-
Fat oil, say linseed oil litharge, commonly called
drying oil

page_text: What I claim as of my Invention is,-
Firstly, the securing or affixing of thin metallic letters on glass, marble,
stone, porcelain, wood, metal, crystal, or any other hard and smooth surface,
without the use of metallic fastenings.
Secondly, the making of thin letters of metal and coating of such with an
enamel surface of any color; also letters made by the electro-galvanic process,
or letters gilded by the electro-galvanic process, and of fixing the same by the
compositions herein named.
Thirdly, the compositions as named in this Specification as applied to
affixing letters on the surfaces of the within-named materials, I do not confine
myself to the precise proportions or quantities of the compositions, as they
vary in accordance with climate or other local causes; but I claim as new the
various materials in these compositions, with the solvents, in any proportions

material herein named
In witness whereof, I, the said Jean Louis Lamenaude, have hereunto
set iny hand and seal, this Fourth day of August, in the year of our
Lord One thousand eight hundred and forty-eight..
