:
CHARLES, FRANCIS POLLAK of 54 Wool Exchange, Coleman Street in the City
of London IMPROVEMENTS IN APPARATUS FOR EXHIBITING ADVERTISEMENTS.
The object of my Invention is to produce a new mode of exhibiting Nainos,
Figures, Designs etc in an attractive manner,
I place in a Box one side of which is made of Glass a small Electric Motor or
Clock Work turning a round wooden upright standing parallel to the Glass Plate
and placed in one corner of the Box.
On the other side of the Box I place a similar upright on an axle so that it can
revolve, and combine the two by a strip of Paper, Linen, or Parchment the sauio
height as the Box.
As soon as the power is put in motion the uprights revolve and the paper passes
continuously before the plate Glass, inside.
The Glass Plate is painted dark and any Name or object to be advertised is
left in plain glass. The Paper Linen or Parchment is painted with different colors
take for example the colors of the Rainbow.
By this arrangement the Name or inscription or anything that is painted on
the Glass will continually change colours as the Paper or linen passes along.
The Battery for moving the Electric Motor, or Clock Work or any other motive
power can be placed either between the Paper in the Box or outside the Box
altogether.
I believe this to be a very attractive and new mode of advertising and
therefore claim for my Invention the combination and construction of Apparatus
as aforesaid.

CHARLES FRANCIS POLLAK, of 54, Wool Exchange, Coleman Street,.in_the_City_
of London "IMPROVEMENTS IN APPARATUS FOR EXHIBITING ADVERTISEMENTS
"
The object of my invention is to provide a new mode of exhibiting names,
figures; designs and the like in an attractive manner.
For this purpose I place in a box, one side or front of which is glazed, a small
electric motor, or a clockwork mechanism, for turning a round woodon upright
or roller standing parallel to the glass front and placed in one corner of the box.
On the other side of the box I place a similar upright or roller on an axle so
that it can revolve, and I connect the two rollers by a strip of paper, linen or
parchment of the same height as the box or nearly so.
As soon as the power is put in motion the uprights or rollers revolve and the
paper passes continuously behind the plate glass inside the apparatus.
The plate glass is painted dark and any name or object to be advertised is left
in plain glass. The paper, linen or parchment is painted with different colours,
take for example the colours of the rainbow, or with diagonal or curved or wavy
lines.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing in which figure 1, represents
a front elevation and figure 2, a horizontal section of an apparatus for oxhibiting
advertisements constructed according to my invention; figure 3, is a front
elevation of the apparatus with the plate glass removed and figure 4, is a similar
view shewing the strip or band of paper or the liko in section, in order more
clearly to show the interior of the apparatus. Similar letters in all the figures
'ropresent similar parts.
a, is the box and b, the plate glass front of same; c, is the electric motor (or
clockwork mechanism may be employed) communicating motion by means of the
cord or band d, to the roller e, placed at one side of the box as shewn and which
revolves in the bearings f, and g, carried by the upright h,; i, is the roller placed
on the opposite side of the box and connected with the roller e, by the strip or
band j, of paper, linen or parchment which is stretched over the two rollers as
shewn and passes continuously behind the plate glass b, over the rollers e, and i,
inside the apparatus; k, and l, are the bearings for the spindle of the roller. The
plate glass b, is painted with a dark colour and the name or object to be adver-
tised is left plain as shewn in figure 1. The strip or band is painted with
different colours or (as shewn in figure 3) with diagonal or curved or wavy lines.
By this arrangement of apparatus, if the motor c, bo put in action, the rollers e,
and i, will be caused to revolve and will carry round them the strip or band j,
and the advertisement painted on the glass b, will continually change colour or
appearance as the paper or linen j, passes along behind it.
The battery for moving the electric motor, or the clockwork or other motive
power can be placed either between the paper in the box, or outside the box
altogether.
Instead of the apparatus being rectangular in horizontal section as herein before
described it may be constructed of a disc painted or marked similarly to the
endless band j, hereinbefore described, the said disc being revolved behind the
glass on which the advertisement is placed as will bo understood without further
description.

page_text: Having thus described my invention and the manner of porforming the same I
would have it understood that what I claim is :—
Firstly. The improved apparatus for exhibiting advertisements substantially as
herein before described and represented in the accompanying drawing.
Secondly In an apparatus for exhibiting advertisements effecting the continuous
change of colour or appearance of the advertisement in the manner substantially
as hereinbefore described and represented in the accompanying drawing.
In Witness whereof I the said Charles Francis Pollak have hereto set my hand
and seal this twenty seventh day of December in the year of our Lord one thousand
eight hundred and eighty three
