Improvements in Forming Advertising Signs, Decorative Panels,
Tablets, and the like.
I ARTHUR MARTYN of 209 The Grove, Hammersmith, in the County of Middlesex
Glass Tablet Manufacturer do hereby declare the nature of this invention to be as
follows:-
My Invention consists in forming ornamental panels, Tablets or signs suitable for
Advertising purposes by means of a sunk or incised design or letters formed in thin
metal or any suitable plastic material & placed under glass in manner set forth,
thereby producing the effect of a pattern or letters cut into a surface. I first prepare
a mould or die having the desired pattern or letters sunk into or raised upon its
surface & by means of such mould or die, and either with or without a matrix, I press
or stamp the pattern into thin metal (preferably lead) papier maché or any suitable
material.
On removal from the mould the thin metal or other material will have the pattern
or letters sunk into it & these sunk letters or pattern can be gilded or coloured as
required.
1 then paint, or otherwise produce in any color upon a sheet of glass a pattern
to correspond exactly with the ground of the moulded article previously described,
the part of the glass exactly corresponding with the sunk letters or pattern being
left clear.
This glass I then place over the stamped metal or other surface so that only the
sunk portions of the latter show through the clear glass and these when properly fixed
together form the complete sign, panel, or Tablet.

Improvements in Forming Advertising Signs, Decorative Panels,
Tablets, and the like.
1, ARTHUR MARTYN, of 209 The Grove, Hammersmith, in the County of Middlesex,
Glass Tablet Manufacturer 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, reference being had to the accom-
panying sheet of Drawings and to the letters and Figures marked thereon, that is to
say:-
My invention consists in forming ornamental panels, tablets, signs and so forth,
suitable for advertising and other purposes, by means of a sunk or "incised" design
or letters formed in thin metal or any suitable plastic material, and placed under or
behind glass so as to produce the effect of a pattern or letters cut into a solid
material.
I first prepare a mould or matrix having the desired pattern or letters sunk into
or raised upon its surface, and I press or stamp thin metal, such as lead for example,
papier maché, or other suitable more or less plastic or ductile material, into or on
to the said mould or matrix by means of a die or follower, or otherwise, so as to
cause the said metal or other material to take the form of the pattern or letters in or
on the mould or matrix.

page_text: On removal from the mould or matrix the thin metal or other material will have
the pattern or letters sunk into it, and this sunk pattern or these sunk letters can be
gilded or coloured as required.
1 then paint, or otherwise produce in any desired colour, upon a sheet of glass a
pattern to correspond exactly with the ground, that is to say the unstamped part or
part not sunk of the moulded article previously described, the part of the glass corre-
sponding with the sunk pattern or letters being left clear. I then place this glass
over the aforesaid moulded article so that the sunk portions of the latter exactly
coincide with, and show through the clear parts of the glass, the painted parts of the
latter then coming in front of, and masking those portions of the article which have
not been sunk, so as to appear to be the surface of the ground or material in which
the design or letters seem to have been cut. The glass and the aforesaid moulded
article, when properly secured together, form the complete sign, panel or tablet,
which may be backed up or mounted in a suitable supporting frame as may be
required.
In preparing the glass, it may be coated entirely on one surface with the colour or
colours, the latter being afterwards removed from those portions which are required
to be transparent by means of stencil plates, and what is known as the brushing-out
process; or the glass may be covered with suitably coloured paper parts of which
are removed where transparency is required or any other suitable means may be
employed for producing a sheet of glass with more or less opaque ground, and
transparent parts corresponding to the sunk pattern or letters.
The sunk design or letters may be gilded or otherwise decorated after they havo
been impressed; or the sheet of metal or other material may be gilded or otherwise
treated prior to being moulded or stamped.
In the Drawing hereto annexed, Figure 1 represents a sheet of metal or other
material having sunk letters and a design formed therein by pressure between a mould
or matrix and a die or follower, in a manner well understood. Figure 2 represents a
sheet of glass which is left transparent at the parts corresponding to the sunk design
and letters on the sheet of metal shown in Figure 1; but the back surface of which
is coloured at the other parts shown by hatched lines. Figure 3 represents the sheet
of glass shown in Figure 2 with the moulded sheet of metal shown in Figure 1.
placed behind it, so that the sunk portions in the sheet of metal show through the
transparent parts of the glass and the desired effect is produced, namely that the
coloured part of the glass represents the surface of a given material such as marble,
slate and so forth, and the sunk portions of the sheet of metal behind have the
appearance of a design or letters cut or carved in such material.
When employing plastic material as the base of the panel, tablet or sign the said
plastic material may be moulded in any convenient manner; for example it may be
placed in a moulding box or frame and the letters or design impressed therein, or
the said letters or design may be placed at the bottom of the moulding box or frame
and the plastic material such as Plaster of Paris, or cement for example poured or
otherwise deposited on to same. I have found that asphalte, any hard variety of
pitch, papier mache, or a composition such as is used by picture frame makers in
the manufacture of gilt and other picture frames and mouldings, form suitable
plastic compositions for the purposes of carrying out this part of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I would have it under-
stood that I am aware that signs, panels and tablets have already been produced
by means of designs or letters cut or carved in a slab of wood or other material
and placed behind a painted sheet of glass, the cut or carved portions only appearing
through the-transparent parts of the said glass and that I make no claim to such
arrangement but that what I do claim is :-
:-
The construction of advertising signs, decorative panels, tablets and the like by

page_text: forming the design or letters in a thin sheet of metal or suitable plastic or ductile
material in or by means of a mould or matrix, and placing the design or letters so
formed behind a sheet of glass made more or less opaque by colour or otherwise but
having transparent parts left therein corresponding to the design or letters formed in
5 the said sheet of metal or plastic or ductile material, substantially as hereinbefore
described, and illustrated in the Drawings hereto annexed.
Dated this 14th day of September 1889.
