Year: 1866

page_text: LETTERS PATENT to James Nall, of No. 6, Queen Street, Leicester,
Engraver, for the Invention of "AN IMPROVED METHOD OF MANUFACTURING
NAME PLATES OF METAL, AND IN PRODUCING ORNAMENTAL DEVICES UPON
METAL PLATES."
Sealed the 17th August 1866, and dated the 20th February 1866.
PROVISIONAL SPECIFICATION left by the said James Nall at the Office
of the Commissioners of Patents, with his Petition, on the 20th
February 1866.
I, JAMES NALL, of No. 6, Queen Street, Leicester, Engraver, do hereby
declare the nature of the said Invention for "AN IMPROVED METHOD OF
MANUFACTURING NAME PLATES OF METAL, AND IN PRODUCING ORNAMENTAL DEVICES
UPON METAL PLATES," to be as follows:-
The object of my Invention is the production of name plates or ornamental
devices in metal by a less costly method than hitherto, which I now proceed to.
describe. I take a sheet of brass, zinc, copper, or other suitable metal to
form the upper surface of the finished plate, and of a thickness corresponding
to the depth required for the inlaying of the letter or other ornamental device
to be produced on the plate; I lay this sheet of metal upon another and
usually a thicker sheet of a similar or less costly metal, and firmly unite the

page_text: two by soldering or otherwise; upon the upper surface of this compound
plate I draw an outline of the letter or other required device, and with a
chisel or other sharp cutting tool I cut through the upper sheet only, and by
the aid of a simple tool, such as a flat chisel or a graver, I prize or tear out
those portions of the upper sheet of metal representing the letter or other
device, thus leaving the blanks or spaces all of one uniform depth, and these
blanks or spaces can be immediately inlayed with metal, wax, colour, or other
desired material.
It will be readily understood by all connected with the trade that this
process is much more simple and economical than the present one of wholly
chipping or cutting. out the letters and other device in a solid sheet of brass,
zinc, copper, or other metal.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Nall in the Great Seal Patent Office on the 18th
August 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES NALL,
of No. 6, Queen Street, Leicester, Engraver, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of February, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said James Nall, Her special licence that I, the said James Nall, my
executors, administrators, and assigns, or such others as I, the said James Nall,
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 IMPROVED METHOD OF MANU-
FACTURING NAME PLATES OF METAL AND IN PRODUCING ORNAMENTAL DEVICES
UPON METAL PLATES," upon the condition (amongst others) that I, the said.
James Nall, my executors or administrators, by an instrument in writing.
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the sail 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 I, the said James Nall, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say) :-
The object of my Invention is the production of name plates or ornamental
devices in metal by a less costly method than hitherto, which I now proceed
to describe. I take a sheet of brass, zinc, copper, or other suitable metal
to form the upper surface of the finished plate, and of a thickness corre-
sponding to the depth required for the inlaying of the letter or other orna-
mental device to be produced on the plate; I lay this sheet of metal upon
another and usually a thicker sheet of a similar or less costly, and firmly
unite the two by soldering or otherwise; upon the upper surface of this
compound plate I draw an outline of the letters or other required device, and
with a chisel or other sharp cutting tool I cut through the upper sheet only,
and by the aid of a simple tool I prize or tear out those portions of the upper
sheet of metal representing the letter or other device, thus leaving the blanks
or spaces all of one uniform depth, and these blanks or spaces can be imme-
diately inlaid with metal, wax, colour, or other desired material.
It will be readily understood by all connected with the trade that this
process is much more simple and economical than the present one of wholly
clipping or cutting out the letter and other device in a solid sheet of brass,
zine, copper, or other metal.
Having now set forth the nature of my Invention, and the manner
in which the same is to be performed, I do in conclusion desire it to be
understood that I claim the method of manufacturing name plates of metal
and in producing ornamental devices thereon, in the manner herein fully set
forth and described.
In witness whereof, I, the said James Nall, have hereunto set my hand
and seal, this Seventeenth day of August in the year of ou Lord
One thousand eight hundred and sixty-six.
JAMES NALL.
