Sealed the 31st October 1861, and dated the 4th May 1861.
Middlesex, do hereby declare the nature of the said Invention for "IMPROVED
SHOW OR WINDOW BOARDS OR TABLETS, TO BE USED FOR ADVERTIZING AND OTHER
PURPOSES," to be as follows:-
The object of this Invention is to produce a show or window tablet which
shall be visible at night, and present the appearance of stained glass. The
Invention consists in printing the required design in colors by lithographic,
typographic, or other means upon paper, cotton, silk, or other material.
This material, so printed, is then rendered transparent by varnish, gum, size,
or other suitable medium, and the tablets thus produced, may either be used in

glass, and caused to adhere thereto by means of varnish, gum, or other
transparent adhesive material.

2nd November 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
JOHNSON, of No. 61, Leader Street, Chelsea, in the County of Middlesex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of May, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Joseph Johnson, Her special licence, thai I, the said Joseph
Johnson, my executors, administrators, and assigns, or such other as 1,
the said Joseph Johnson, 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 "Ix-
PROVED SHOW OR WINDOW BOARDS OR TABLETS, TO BE USED FOR ADVERTIZING
AND OTHER PURPOSES," upon the condition (amongst others) that I, the said
Joseph Johnson, 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 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 1, the said Joseph. Johnson, 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 in writing that is to say:-
The object of this Invention is to produce a show or window tablet
which shall be visible both by day and night, and present the appearance
of stained glass. The Invention consists in printing the required design in

page_text: colors by lithographic, typographic, or other means upon paper, cotton, silk,
or other material. This material so printed is then rendered transparent
by varnish, gum, size, or other suitable medium, and the tablets thus produced
may either be used in that state or they may be placed loosely behind glass,
or applied to the glass, and caused to adhere thereto by means of varnish,
gum, or other transparent adhesive material.
Such being the nature and object of my said Invention for Improved
Show or Window Boards or Tablets for Advertizing and other Purposes,"
I will now proceed to describe more in detail the manner in which the same
is to be or may be performed or carried into practical effect.
In carrying out this Invention 1 first print the required design upon
paper, or other suitable material in colors by lithographic, typographic, or other
printing process, printing some or all of the colors twice or oftener in order to
give the required solidity, so as when finished more closely to imitate
stained glass, and for the purpose of carrying out the resemblance thereto
more perfectly, I form a boundary line round the edges of all the letters
or other parts of the design, by printing in size or other adhesive material
and applying metallic leaf or bronze powder, thereto, so as to imitate what
is termed the leading," in stained glass work, or this effect may be produced,
though more imperfectly, by printing the boundary lines or leading" in any
very opaque color or substance. I next take the print so produced and
prepare it by the application to its face of size, gum, isingiass, or other similar
transparent substance, and apply the same evenly to a piece of sheet or other
glass. When perfectly dry, I complete the transparency by applying to the
back of the print by means of a brush or otherwise, a coating of varnish, oil, or
oil of turpentine.
It may here be observed that instead of being applied to the glass by an
adhesive material as above-named, the print may be placed loosely behind
the glass or even stretched on a frame without any glass, if preferred, in which
instance the prints merely require varnishing or treating with oil of turpentine
on both sides, the previous preparation with gum, size, or isinglass being
unnecessary. The material upon which the design is printed may be paper,
silk, cotton, or other suitable material, but for very transparent tablets I
prefer the paper known as "French bank post," or tracing paper.
Having now described the nature and object of my said Invention for
"Improved Show or Window Boards or Tablets for Advertizing and other
Purposes," together with the manner in which the same is to be or may
be performed or carried into practical effect, I would remark in conclusion that

page_text: I do not claim as new the mere application of printed designs to glass by means
of a transparent adhesive medium, as I am aware that a somewhat similar
process is used in the art known as "diaphanie," but what I do claim as
my Invention, is the manufacture or production of show or window boards
or tablets in imitation of stained glass, and visible both by day and night by
means of the process above described.
