I, JAMES BENNETT, of No. 41 Eastcheap, in the City of London, Gentleman
o hereby declare the nature of this invention to be as follows:-
My invention relates to a device for the better and more attractive display of
dvertisements which may be adapted to existing mechanism of any kind or may
be separately operated.
In carrying my invention into effect, I cause the design, word, or words to be
cut out in a sheet or sheets of metal or other suitable substance, so that any
kind of back ground may be distinctly seen, causing said design to be clearly
delineated against the surface. The surface may be, in some cases, a sheet of
glass or other transparent substance, the design being left clear, and the rest of

said surface being colored, rendered reflecting or opaque.

are revolved, the alternation of colors appearing through the open space, or
transparent portion of the design, word or words, produces a prismatic_effect
which is effective for advertising purposes. In order to vary the effect, I may
cause some of the discs to be perforated, or to have transparent or semi
transparent spaces, through which the colors of the disc or discs behind may
appear, or may be varied in shade. Also, in some cases, I may use an interior
light, to enhance the effect.
The necessary motion of the discs may be imparted in various ways, for
instance, when the advertising device according to my invention is applied to a
vehicle of any kind, said motion may be derived from the moving axles thereof,
by bands, belts, toothed or frictional gearing. Or, in other cases, clockwork,

electric, air, gas water or steam motors may be used for this purpose.
an interior lamp other than an electric lamp is employed in connection with the
device, the required motion may be obtained by the ascension of the products
a further
of combustion, or by the natural draught or air inlet. And, as
modification, may, instead of discs, use one or more circular bands, suitably
suspended to revolve concentrically, and colored, or perforated, to produce the
same prismatic effect as hereinbefore described.
Although, in the practical application of my said invention, I prefer to produce
a prismatic effect by constant and rapid changes of color as aforesaid, I may in
some instances arrange the discs or bands so that some part of the design, word
or words is caused to apparently change its position, or otherwise become altered so
as to attract attention to the advertisement, and each or any of the herein described
modifications may be adapted to any existing vehicle, motor lamp or machine.

COMPLETE SPECIFICATION.
Improvements in Advertising:
I, JAMES BENNETT of 41 Eastcheap, London in the County of Middlesex,
Advertisement Contractor 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:-
My invention relates to a device for the better and more attractive display of

page_text: advertisements, which may be adapted to existing mechanism of any kind, or may
be separately operated.
In order that my invention may be more clearly understood, I have appended
the accompanying drawing which shows the principle of said advertising device.
In carrying my said invention into effect, and applying same to wheeled
vehicles, cause the design, word, or words to be cut out of the side of the
cart or vehicle or out of metal or other material inserted .therein, so that any
kind of background may be distinctly seen, causing said design to be clearly
delineated against said background. The surface may in some cases be a sheet
of glass or other transparent substance, the design being left clear and the rest
being coloured, reflecting or opaque.
Behind the design, word, or words, in the interior of the cart or vehicle, I
arrange a disc d. If desired, said disc may be connected by a spinille with
another disc on the other side of the vehicle, as shown in the drawing, said
disc or discs being supported by, and allowed to rotate within suitable arms or
supports u. The discs are divided on the face into any convenient number of
sections, coloured according to taste. This is shown in the drawing where the
side is shewn as broken away. When said disc or discs is or are revolved, the
alternation of colours appearing through the open space or transparent portion of
the design produces a prismatic effect, which is very effective for advertising
purposes. In some cases may cause the dises to be perforated or I may arrange
on them any other device such as concentric rings or a star. Also an interior light
may be employed to enhance the effect.
The necessary motion of the dises is obtained preferably from the axle of the
vehicle by means of a band or chain " but any suitable toothed or frictional gearing
may be employed for the purpose.
It will be seen that the advertising device above described may also be applied
in other ways.
The required motion of the discs, in a stationary advertisement
may be obtained from a steam, gas, clockwork, electric, or other motor working the
axle of the disc or discs aforesaid. Also when an interior lamp other than an
electric lamp is employed, the required motion may be obtained by the ascension of
the products of combustion or by the natural draught or air inlet working a fan or
fans which in turn works one or more of the disc axles.
As a further modification I may, instead of discs, use one or more circular bands
suitably suspended to revolve concentrically, and coloured or perforated to produce
the same prismatic effect as herein before described.
Any number of discs may be employed, and one axle may be made to drive the
others by means of band, chain, or cog gear, such as that shown in the drawing.
Although, in the practical application of my said invention, I prefer to produce
a prismatic effect by constant and rapid changes of colour as aforesaid, I may in
some instances arrange the discs or bands so that some part of the design, word, or
words is caused to apparently change its position, or otherwise become altered so as
to attract attention to the advertisement, and each or any of the herein described
modifications may be adapted to any existing vehicle, motor lamp or machine.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :
In an advertising device, the employment of a disc or discs or moving surfaces
for varying the colors or signification of open signs or the like, especially applicable
to vehicles substantially as herein set forth and partly shewn by the appended
drawing.
