HERBERT JAMES TEAR Photographer 12 Clapham Road Stockwell, S.W. do
hereby declare the nature of this invention to be as follows:-
My invention consists of an endless band upon which advertisements are
displayed, set in motion by means of a current of air being produced by the motion
of a vehicle, or the heat of a lamp, or in any other convenient manner.
I make provision for directing the current of air on opposite sides of the wheel as
the vehicle moves in opposite directions.

I HERBERT JAMES TEAR of 12 Clapham Road Stockwell, London S.W.
Photographer 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 :-
My invention consists of an endless band upon which advertisements are
displayed and means whereby the said band is set in motion by a current of air acting
upon the vanes or arms of a wheel the air current for the purpose being produced
in any convenient manner such as by the motion of a vehicle the heat of a lamp or
by ordinary air currents or wind.
I may provide means for directing the current of air to the wheel for example,
when the apparatus is applied to a vehicle I may employ directing plates for the
air currents for conducting the air to the periphery of the wheel in whichever
direction the vehicle may travel.
In order that my invention may be well- understood I will now. proceed to
describe a manner in which it may be performed.
I have illustrated the apparatus as it may be arranged when it is to be applied
to a vehicle such for example as to the door or side of a railway carriage from
which its other applications will also be understood, C representing the door or
other part of the carriage to which the apparatus is affixed. It consists of a series
of rollers A mounted in bearings in a box or frame which is shewn as consisting of
end plates B connected by tie rods 62 and inserted into an opening in the door or
other part of the carriage the said opening being glazed at its inward side (at b)
the glass being secured by a frame 3. The plate at the outer side of the opening
secures the box or frame in place in the opening. An endless band or web G of
paper or other flexible material is passed around the rollers A as shewn in Figure 2
On the side of
so that when the rollers rotate the band or web travels with them.
the web which is presented behind the glass b and can be seen therethrough the
advertisements announcements or the like are printed or otherwise marked or
attached. One of the rollers has fixed to it or to its axis a toothed wheel a with
which gears a pinion d on one end of a spindle D mounted in bearings secured to
the plate 6 the other end of the spindle d having secured to it a crown wheel d
with which gears a pinion e secured to an axle e supported in bearings in the
plate and in the casing formed by the disc E' and pieces e³ which leave openings
r...31

page_text: at the periphery of the casing for the admittance of air. The casing is secured to
the plate as shewn and may be strengthened by the curved tie rods e connected
at one end to the plates 3 and at the other end to the plates F F2 which act as
directors of the air currents. On the axle e is secured the wheel E having wings
or blades on its periphery as shewn by the dotted lines in Figure 1. This wheel
may be made of any suitable material such as mica or celluloid for example.
When the vehicle is moving in the direction shewn by the arrow w the air is
directed by the plate F as shown by the arrow x onto the wheel E and when the
vehicle is moving in the direction shewn by the arrow y the air is directed by the
plate F as shewn by the arrow z outo the said wheel E which in either case is thereby
caused to rotate and through the wheels e and d spindle D pinion d and wheel a to
drive the roller A to which the wheel a is affixed and so the band or web G is
moved along by frictional contact or it may be by positive driving effected for
instance by pins on the rollers entering openings in the said band or web and thus
the advertisements, announcements or the like on the exposed side of the said band
or web G are exhibited successively before the glass b. It will be readily under-
stood that the gearing may be arranged (for example after the manner of counter
gearing) so that the band or web G has an intermittent motion and an advertisement
or the like can remain exposed for a short time before the band is moved on again.
Although I have described the apparatus as being attached to a vehicle it will be
understood that it can be attached to any suitable place and that the wheel E may
be in any suitable position relatively to the roller and band portion and be connected
therewith by any suitable gearing. For instance the wheel E may be mounted in
a situation exposed to the wind or to an updraught created by a lamp or heating
device and its motion of rotation be conveyed by gearing to the rollers A which
may be in any suitable number and arranged in any suitable way so that they give
motion to the band G.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1. An apparatus for displaying advertisements wherein a band having adver-
tisements thereon has movement imparted to it by means of a device operated by
currents of air substantially as hereinbefore described.
2. An apparatus for displaying advertisements consisting of the combination of
parts substantially as herein before described and illustrated by the accompanying
drawings.
