COMPLETE SPECIFICATION.
An Improved System of Day and Night Advertising, applied to
Vehicles, and Apparatus for Operating the same.
I, RICHARD EDWARD SAUNDERS, of 6, Dordrecht Mansions, Brook Green, London,
of no occupation, 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:-
This invention refers to the application of my system of improved day and night
advertising devices as described in my British Patent No. 18365 of 1897, to vehicles
of all kinds, and operating and illuminating the same either by electricity or by
mechanical means deriving the necessary power from the wheels of the vehicle, or
from the motor by which the vehicle is driven. I will now describe a method of
operating the device from the wheels of the vehicle.
On the hub of one of the wheels I form or attach a pulley or sprocket wheel, from
which a strap or chain conveys the power to another pulley or chain wheel, which by
means of mitred or worm wheels, chain wheels and chains with rods and bearings, or
their equivalents transmits the power where required.
I will now describe this form of my invention with reference to the accompanying
drawings in which :—
Fig. 1 shews an elevation of an omnibus to which my improved advertising device,
and the means for operating the same is fitted.
Fig. 2. is an enlarged horizontal section on the line x-x of an alternative method of
keeping in motion the coloured surface behind the advertisement.
Fig. 3 is an elevation of part of the coloured band, shewn in Fig. 2 and of the frame
which supports the tension rollers g g¹ the latter being preferably caused to rotate by
sprocket gear.
a is a pulley mounted upon one of the axles of the vehicle, so that it rotates when
the vehicle is moving. 6 is a driving band running over the pulley at one end, and
driving a similar pulley cat the other end. dis a toothed bevel wheel attached to, or
formed integrally with the pulley c. e is a toothed bevel wheel, the teeth of which gear
with those of the bevel wheel d so that the latter drives the former. f is a vertical shaft
driven by the bevel wheel e. The shaft fis provided with suitable bearings attached
to the side of the vehicle, and its upper end is terminated by one (g) of a pair of
tension rollers g g₁ disposed one at each end of the frame h. The tension roller g' is
preferably driven from the roller g by the sprocket chain g² each of the rollers being
provided with chain wheels g³ to engage with the chain. The upper and lower ends
of each of the rollers g g¹ are furnished with toothed wheels jj, to cause the continual
rotation of a multi coloured band k. The latter consists of an endless band running
over the tension rollers g g¹ and its rotation may be secured by the following
arrangement; other devices can however be used for the same purpose. The edges k¹
of the band k may be lined with leather or otherwise made stiffer than the body of
the band and a number of spaces k² may be left therein corresponding in pitch to
that of the teeth of the toothed wheels jjat the upper and lower ends of the tension
rollers. Therefore the rotation of the wheels jj with the tension rollers secure that
of the band. The coloured bands or the discs described in my specification No. 18365

page_text: aforesaid rotate behind an opaque screen in which transparent letters forming the
advertisement are left. The result is that these letters appear to be constantly
changing colour. Both the band and discs are made transparent so that lights can
be employed at night to illuminate same thus making a day and night advertise-
ment.
If necessary the power obtained by the movement of the vehicle may be utilised
to drive a small dynamo with or without storage cells in any well known way such as
for instance by gearing from the axle and in combination with a motor to operate the
device by electricity.
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 application of the night and day advertising device described in my
specification No. 18365 of 1897 to vehicles of all descriptions, as herein described and
set forth.
2. The combination with the said advertising device as applied to vehicles, of
electricity either as an illuminant, or as both an illuminant and motor, as herein
described and set forth.
3. The combination with the said advertising device as applied to vehicles, of the
special mechanical apparatus shewn or its equivalent, as herein described and set
forth.
4. The combination with the said advertising device of the vertical rollers g g¹ and
rotating coloured band k, as herein described and set forth.
Dated this 23rd day of Uctober 1897.
