PROVISIONAL SPECIFICATION.
An Improved Method and Apparatus for Exposing Advertisements.
I, THOMAS RALPH DOUSE, of 11 Gresham Street, City of London, Manufacturer,
do hereby declare the nature of this invention to be as follows:-
The apparatus consists of a rectangular or other shaped case into which is fitted a.
train of rollers mounted upon centres and connected together for rotation by means
of cog wheels, so that all the rollers revolve together at an uniform rate, the train of
rolls being actuated by an electro magnet placed in open circuit with a clockwork
arrangement for the purpose of closing the circuit at intervals.
On the circuit being closed the magnet by means of a paul and ratchet -attachment
causes the train of rolls to move round sufficiently to expose a line of printed matter
through a corresponding orifice cut in front of case opposite the centre line of each
roll, so that a different advertisement is displayed at each movement.
For the purpose of presenting a plain front, as many flats, as there are lines of
printed matter, is formed upon the periphery of the rollers, and in the caso of whole
sheet advertisements, three flats only are required upon the periphery of the rollers
the apertures in front of case being dispensed with.
As the advertisements would not require to be run the whole of the 24 hours, an
arrangement is made for automatically opening the main circuit a certain proportion
of the time for the purpose of economizing the battery power.
By another arrangement, the train of rolls are dispensed with and only a one
roller top and bottom is used, the advertisements being wound in series upon the
rollers in that case a continuous action is used and in place of the magnet an electro
motor is employed, or a clockwork arrangement may be substituted with an automatic
attachment for reversing the motor on arriving at the end of the roll. The advertise-
ments by being divided can be shown a line at a time as with the train of rolls and a
continuous action may be obtained by making an endless band of the advertisements
and running same round the front, top, back and bottom of case on rollers.

COMPLETE SPECIFICATION.
An Improved Method and Apparatus for Exposing Advertisements.
I, THOMAS RALPH DOUSE, of 11 Gresham Street, City of London, Manufacturer,
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:
The apparatus consists of a rectangular or other shaped case A, as in the annexed
drawings, Figures 1 and 2, into which is fitted a train of many sided rollers B
mounted upon centres and connected together for rotation by means of cog wheels C,
so that all the rollers revolve together at an uniform rate. The train of rolls may be
actuated by an electro magnet E, Figures 3 and 4, placed in open circuit with a
clockwork arrangement for the purpose of closing the circuit at intervals, or at each
rotation of the stud D seen in Figure 2.
On the circuit being closed, the magnet E, by means of a pawl and ratchet
attachment F, causes the train of rolls B to move round sufficiently for each to
expose a line of printed matter through a corresponding orifice cut in front of the
case A opposite the centre line of each roll, so that a different advertisement is
displayed at each movement.

Hats only being required upon the periphery of the rollers, the apertures in front of
case are dispensed with.
As the advertisements would not require to be run the whole of the 24 hours, an
arrangement can readily be made by a skip wheel for automatically opening the main
circuit-a certain proportion of the time for the purpose of economising the battery.
power.
"Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is :-
The combination of many sided rollers, in gear, and having advertisements on the
flat surfaces, which can automatically and periodically be exposed in lines, and be
changed by the means set forth, and as shown by the annexed drawings.
The 16th day of April 1890.
