PROVISIONAL SPECIFICATION.
Improvements in and relating to the Exhibition of Advertisements,
Devices and the like.
I, JOSEPH SHALLCROSS, of 27, Langsett Road, in the City of Sheffield, Stove Grate
Fitter, do hereby declare the nature of my invention to be as follows:-
My invention relates to improvements in or relating to the exhibition of all kinds
of advertisments, signs and other devices, by means of illumination either by
means of a lantern or by other means, the object being to produce a brilliant effect
at a moderate outlay.
Such an effect now obtained by the use of cut glass crystals strung upon wires
and arranged in the form of letters or devices as the case may be; these letters
or devices are surrounded by an opaque or semi opaque border or background, and
are lighted from the back.
Each name or device has to be made separately and for its special purpose.
According to my invention, I utilise glass which is embossed or cut upon one
(or both) sides, into squares, diamonds or other devices; for example, I take a sheet
of such glass or more than one if desired according to the size required, and frame
it as preferred and upon the back of the glass I project the design, device or
advertisment by means of a lantern or other incans, changing it as I wish.
Dated the 22nd day of May 1897.

Improvements in and relating to the Exhibition of Advertisements,
Devices and the like.
I, JOSEPH SHALLCROSS, of 27, Langsett Road, in the City of Sheffield, Stove Grate
Fitter, 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:-
My invention relates to improvements in the exhibition of advertisments, signs,
devices and the like, by illumination and more especially by the aid of a lantern
and interchangeable slides or their equivalents, the object being to produce a very
brilliant effect, with a moderate cost.
The accompanying drawings illustrate the nature of my invention and the manner
in which it may be put into practice.
Fig. 1, is an edge view, and Fig. 2 a face view of a piece of glass of the pattern
which I prefer to use.

page_text: Fig. 3, illustrates the manner in which the invention may be carried out.
Hitherto the effect which I produce has been obtained by the use of glass crystals
cut into form and strung upon wires, and arranged in the form of letters or devices
as the case may be; these letters or devices are placed in position and are surrounded
by an opaque or semiopaque border or background, and are illuminated from the
back.
Each name or device has to be made separately and can only be used for its
special purpose.
According to my invention I use one or more flat pieces or sheets of glass embossed
upon one or both sides, such as G, shown in Figs. 1 and 2, which represents a piece
of sheet glass having one face covered with small pyramidal projections P, but other
forms may be used if desired, such as hemispheres, diamond, hobnail or other similar
forms of embossed projections.
I take a sheet of such embossed glass, G, or more than one if required and fix it
or them into a frame F', such as a window frame, or in any other way according
to the position and requirements of the case.
I prepare the lettering or device in the form of a lantern slide S, and I project
it in the usual manner by the aid of a lantern L, upon the back of such glass
screen G, the result being that the letters or device appear with very brilliant and
sparkling effect upon the embossed side of the glass.
My method or system enables an endless variety of designs, advertisments and
the like to be shown upon the same screen with the appearance of having been made
separately in crystals strung together.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim, is:-
1--The improved method of and means for exhibiting advertisments and the like,
consisting in projecting such devices by the aid of a lantern upon the back of a
screen of glass having its outer face embossed as hereinbefore described and shown.
2-In the exhibition of advertisments and the like by means of lantern slides
the use of a glass screen having an embossed outer surface to increase the brilliancy
of the representations, as herein before described and set forth.
Dated the 21st day of February 1898.
