case
We make the case preferably of galvanized iron and paint the surface upon
which the sign is to appear with any suitable vitrifiable paint leaving the letters or
other signs in intaglio so that the sign appears in galvanized metal upon a coloured
surface.
Within the case we provide suitable stays and a series of gas piping to distribute
a supply of gas within the closed case so that it becomes fully charged. We
puncture small holes through the walls of the closed case upon the parts representing
the letters or other signs so that the galvanized surface representing the sign is
illuminated by lighting the jets of gas which issues from the puncture holes.

COMPLETE SPECIFICATION.
Improvements in Illuminated Signs for Advertising and other
Purposes.
We THOMAS PUNTIS of 8 Bryancourt Buildings Elm Grove Southsea Sign
Writer and JOHN GEORGE HEAL of "Arnewood" Nelson Road, Southsea,
Commercial Traveller both in the County of Hants do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
Our invention relates to signs for advertising and other purposes which are
capable of being illuminated in a manner to be visible at night.
For this purpose we produce the sign upon one or more sides of a closed case,
according to the position in which the case is to be placed.
We make the case preferably of galvanized iron and paint the surface upon
which the sign is to appear with any suitable vitrifiable paint leaving the letter or
other sign in intaglio so that the sign appears in galvanized metal upon a coloured
surface.
Within the case we provide suitable stays and a series of gas piping to distribute
a supply of gas within the closed case so that it becomes fully charged. We
puncture small holes through the walls of the closed case upon the parts representing
the letters or other signs so that the galvanized surface representing the sign is
illuminated by lighting the jets of gas which issue from the punctured holes.
In order that our invention may be more readily understood we refer to the
accompanying drawing representing an advertising sign made according to our
invention.

page_text: Figure 1 is a front elevation of the apparatus bearing the letter E as an example
of any letters or other signs which may be painted on the outer surface as
Figure 2 is a front elevation, the front wall of the case being removed.
Figure 3 is a sectional elevation taken upon the line x y in Figure 2.
A is the case in which a gas pipe B is fitted to distribute a supply of gas
uniformly therein through the holes b. C are cross plates or stays carried
throughout the case to avoid any risk of collapse in case of the supply of gas being
suddenly turned off while the lights are burning. Openings c are made in the cross
plates to allow free circulation of the gas to all parts of the interior of the casing.
The front wall D of the case A is secured by riveting or in other suitable ways
so as to close upon the case making an air tight closure. Upon this outer wall the
sign, being letters or other designs, are painted as desired with any suitable
vitrifiable paint leaving an outline of the letter or main design in intaglio as
represented in the drawing by the diamond shape spaces d enclosing each perfora-
tion or small burner e from which gas will issue to be lit when the case is charged
with gas as required to illuminate the letters or design of the sign at night or when
it is dark.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
A combined day and night advertising sign consisting of a gas reservoir upon the
outer walls of which suitable signs may be painted for show by daylight and
perforated for illumination in darkness substantially as described.
Dated this 27th day of April 1891.
