I, WILLIAM NICHOLAS ARMSTRONG, of No. 22, Leabon Street, West Ham,
London, E., Builder, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in apparatus for advertising purposes;
and is designed with the object of providing means for projecting suitable
advertising matter through an opaque screen in such a manner as to cause
the said advertising matter to appear conspicuously and attractively upon such
screen, the whole apparatus constituting a convenient, inexpensive and attractive
medium for displaying advertisements in shop windows, upon street lamps,
hoardings, railway stations, and other suitable places.
According to my invention I provide a case of suitable shape and material,
having a compartment at the rear for the reception of an oil-lamp, electric
light, gas-jet or other suitable lighting medium, a chimney being provided
where au oil or gas lamp is employed for lighting purposes. An opening is pro-
vided in the case at the front of the lighting medium, such opening communi-
cating with the front of the case. It will be understood that the surfaces of
the solid parts of the case diverge from the opening to the front of the appa-
ratus, so as to provide for the screen on which the advertisements are displayed,
being considerably larger than the rear opening through which the light is
thrown from the lamp or its equivalent.
At or near the front of the apparatus a screen is provided, such screen being
formed of porcelain or suitable opaque glass.
At a suitable distance to the rear of this opaque screen grooves are provided
in the sides of the case, in which grooves slides are adapted to be movably held,
such slides being formed of transparent glass or its equivalent and having dis-
played thereon suitable pictorial or other advertising matter.
A shutter is provided to cover the rear opening in order to shut off the light
when required, such shutter working in grooves or guides and being operated
by clockwork or other suitable mechanism which however forms no part of the
present invention. The said shutter is preferably so arranged as to slide slowly
downward and thereby admit the light to the top of the advertising slide first.
By this means the advertising matter at the top of the slide is first displayed,
the advertisements below being gradually displayed as the shutter slowly slides
downward.
When the shutter has cleared the rear space or opening and the whole of the
advertising matter on the slide is in view upon the opaque screen, the shutter
is caused to spring upwards and recover the said opening, by means of a spring
or other suitable means.
The case is provided with an enlarged base to enable the apparatus to” bệ
stood in a shop window or other suitable situation.
Although I have described the apparatus as having one displaying screen, I
may so form such apparatus by slightly modifying the construction thereof, as

page_text: to be capable of exhibiting advertisements upon four or other desirable number
of screens, and provision may be made for adapting the apparatus to be used
in connection with shop lamps, street lamps, hoardings or the like, without
departing from the spirit of my invention.

I, WILLIAM NICHOLAS ARMSTRONG, of No. 22, Leabon Street, West Ham,
London, E., Builder, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in, and by the following statement:—
This invention relates to improvements in apparatus for advertising purposes,
and is designed with the object of providing means for projecting suitable
advertising matter through a semi-opaque screen in such a manner as to cause
the said advertising matter to appear conspicuously and attractively upon such
screen, the whole apparatus constituting a convenient, inexpensive and attractive
medium for displaying advertisements in shop windows, upon street lamps,
hoardings, railway stations and other suitable places.
And in order that this my said invention may be the more readily understood
and carried into practical effect, reference is hereby made to the accompanying
sheet of illustrative drawings, wherein :
Fig. 1 is a side sectional elevation of an apparatus for use in shop windows,
constructed in accordance with my invention, the manner of inserting the
advertising slide being shewn, while the shutter is removed, and
Fig. 2 is a similar view but with the shutter shewn and advertising slide in
position.
Referring to the drawings, wherein like letters of reference indicate corre-
sponding parts throughout both figures, a is a case of suitable shape and
material, having a compartment at the rear for the reception of an oil-lampe,
electric light, gas-jet or other suitable lighting medium, a chimney being pro-
vided where an oil or gas lamp is employed for lighting purposes. An open-
ing d is provided in the case at the front of the lighting medium, such open-
ing communicating with the front of the case. It will be seen that the surfaces
of the solid parts of the case diverge from the opening to the front of the
apparatus, so as to provide for the screen on which the advertisements are dis-
played, being considerably larger than the rear opening through which the
light is thrown from the lamp c or its equivalent.
At or near the front of the apparatus a screen e is provided, such screen being
formed of porcelain or suitable opaque glass.
At a suitable distance to the rear of this opaque screen e grooves f are pro-
vided in the sides of the case a, in which grooves slides are adapted to be
movably held, such slides being formed of transparent glass or its equivalent
and having displayed thereon suitable pictorial or other advertising matter.
A shutter is provided to cover the opening d in order to shut off the light
when required, such shutter working in grooves or guides and being operated
by clockwork or other suitable mechanisin (not shewn) which however forms no
part of the present invention. The said shutter is preferably so. arranged as to

page_text: slide slowly downward and thereby admit the light to the top of the advertising
slide first. By this means the advertising matter at the top of the slide is first
displayed, the advertisements below being gradually displayed as the shutter
slowly slides downward.
When the shutter has cleared the space and the whole of the advertising
matter on the slide gis in view upon the opaque screen e, the shutter is caused
to spring upwards and recover the said opening, by means of a spring or any
other suitable means.
The case a is provided with an enlarged base to enable the apparatus to be
stood in a shop window or other suitable situation.
Although I have shewn the apparatus with one displaying screen. I may so
form such apparatus by slightly modifying the construction thereof, as to be
capable of exhibiting advertisements upon four or other desirable number of
screens, and provision may be made for adapting the apparatus to be used in
connection with shop lamps, street lamps, hoardings or the like, without depart-
ing from the spirit of my invention.
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 improvements in apparatus for advertising purposes, consisting essen-
tially in a case a having a compartment & to hold an illuminating medium,
said compartment communicating with a porcelain or opaque glass displaying
screen e behind which and interposed between same and the medium, an adver-
tising slide is adapted to be removably held so that the light can shine through
same on to the said screen; and a shutter for cutting off the light to such
slide and screen, substantially as herein before described and illustrated by the
accompanying drawings.
I
2. In apparatus for displaying luminous advertisements, the employment of
a case containing an illuminating medium and having fixed opaque porcelain
screens at a suitable distance behind which transparent slides having displayed
thereon advertisements are adapted to be removably held in position: in com-
bination with suitably controlled shutters adapted to shut off the light from said
screens and slides at pre-arranged intervals, substantially as described.
