page_text: LETTERS PATENT to Frank Trevisany, of 81, Fentiman Road,
Clapham Road, in the County of Surrey, for the Invention of
"IMPROVEMENTS IN THE MANUFACTURE OF METAL SHOW TABLETS FOR
ADVERTIZING PURPOSES."
Sealed the 29th January 1875, and dated the 25th August 1874.
PROVISIONAL SPECIFICATION left by the said Frank Trevisany at the
Office of the Commissioners of Patents, with his Petition, on the
25th August 1874.
I, FRANK TREVISANY, of S1, Fentiman Road, Clapham Road, in
the County of Surrey, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN THE MANUFACTURE OF METAL SHOW TABLETS FOR
ADVERTIZING PURPOSES," to be as follows:-
This Invention has for its object improvements in the manufacture of
metal show tablets for advertising purposes.
In the metal shame tablata at moment wood for adventicin

page_text: either by colored enamels or by casting them with the tablet. The
disadvantages of these methods are that the enamel is liable to crack,
as also is the tablet itself if it be made of cast metal.
Now according to. my Invention I form the letters, trade marks, or
devices of which the advertisement consists raised in relief, and standing 5
out from the surface of the tablet; or, if preferred, they may be sunk.
This result may be produced either by stamping the tablet between
suitable dies or by passing it, between suitably formed rollers.
The raised or sunk portions, or the ground, or both, may be colored
or enamelled, or they may be "mat" or burnished so as to make the 1
letters, trade marks, or devices stand out more clearly and legibly.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frank Trevisany in the Great Seal Patent Office
on the 24th February 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANK
TREVISANY, of 81, Fentiman Road, Clapham Road, in the County of
Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of August, in the year of our
Lord One thousand eight hundred and seventy-four, in the thirty-eighth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Frank Trevisany, Her special license that I,
the said Frank Trevisany, my executors, administrators, and assigns, or
such others as I, the said Frank Trevisany, my executors, adminis-
trators, 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 "IMPROVEMENTS IN THE
MANUFACTURE OF METAL SHOW TABLETS FOR ADVERTIZING PURPOSES," upon the
condition (amongst others) that I, the said Frank Trevisany, my
executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, should particularly describe

page_text: 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 Frank Trevisany, do hereby declare
the nature of the 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 :—
This Invention has for its object improvements in the manufacture of
metal show tablets for advertizing purposes.
In the metal show tablets at present used for advertizing purposes the
letters, trade marks, or other devices have been made upon the tablet
either by colored enamels or by casting them with the tablet. The
disadvantages of these methods are that the enamel is liable to crack,
as also is the tablet itself if it be made of cast metal.
Now according to my Invention I form the letters, trade marks, or
devices of which the advertisement consists raised in relief, and standing
out from the surface of the tablet; or if preferred, they may be sunk.
This result may be produced either by stamping the tablet between
suitable dies or by passing it between suitably formed rollers.
The raised or sunk portions, or the ground, or both, may then be
colored or enamelled, or they may be "mat" or burnished so as to
make the letters, trade marks, or devices stand out more clearly and
legibly.
In order that my Invention may be fully understood and readily
carried into effect, I have shewn in the Drawings hereunto annexed an
examble of a show tablet constructed according to my Invention.
Figure 1 is a front view of the tablet, and Figure 2 a transverse
section of the same. It is formed from sheet metal, which has impressed
upon it either by stamping or pressing between dies or rollers a raised
frame or border all around its edge, and also the various letters, trade
marks, and devices of which the advertisement consists. After the plate
has been stamped or impressed the raised or sunk portions, or both, are
colored or enamelled, or rendered "mat" or burnished, as may bo
desired.

page_text: In the example shewn in the Drawing the main portion a, a, of the
sunk ground may be coated with white enamel, and the partially raised
portion b, b, of the ground with green enamel, whilst the raised letters
and other raised devices and the raised frame or border may be colored
in imitation of gold. Show tablets constructed in this manner are
elegant in appearance, brilliant in colour, very light, strong, and durable.
They require neither to be framed nor glazed, as they are made with an
ornamental border forming a frame, and this can be washed with soap
and water when necessary. This renders the show tablets less expensive
and much less liable to injury than those made of glass, or which need
the protection of glass to keep them clean.
Having thus described my Invention, I would state that I claim, the
manufacture of metal show tablets for advertising purposes, substantially
in the manner herein described.
In witness whereof, I, the said Frank Trevisany, have hereunto
set my hand and seal, this Twenty-third day of February, in the
year of our Lord One thousand eight hundred and seventy-five.
