PROVISIONAL SPECIFICATION.
Wind Driven Mechanical Advertising Apparatus.
JAMES LOWE PURDY 72, South Lambeth Road London, S.W., Student, do-
hereby declare the nature of this invention to be as follows:-
My invention consists of a fan or motor, driven or actuated by wind pressure
(after the manner of wind mills) to be attached to public vehicles aud elsewhere,
for advertising purposes.
The fan which revolves in accordance with the wind pressure is preferrably made.
of aluminium, and is connected by means of cog gearing or otherwise to a larger
disc, which is thus caused to rotate slowly. The said larger or slowly rotating
disc, has displayed upon it, the advertisement matter and may be illuminated by
means of electricity or otherwise, when necessary. The whole machine, or parts.
thereof is a mechanical advertising device, to be attached to the interior or exterior.
of public vehicles, ships, and elsewhere and fixed and displayed in public places.

Wind Driven Mechanical Advertising Apparatus.
JAMES LOWE PURDY Student, 72, South Lambeth Road Loudou, do hereby
declare the nature of this invention and in what mauner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
My invention consists of a wind motor wind mill or wind vane or vanes driven.
or actuated by wind pressure after the manner of wind mills to be attached to public
vehicles and elsewhere for advertising purposes.
The said wind motor wind mill or wind vane or vanes rotates in accordance with
the wind pressure is prefferably made of aluminium and is connected by means of
suitable gearing to a disc, wheel, surface or body which is thus caused to rotate
slowly.
The said slowly rotating disc, wheel surface or body is partly made in separate
sections, admitting of each section being removed from the disc, wheel, surface or
body, without disturbing the remaining sections.
Upon these said sections is displayed the advertisment or other matter, which
may be illuminated by means of electricity or otherwise.
The whole machine or a sufficient portion thereof is a mechanical advertising
device to be fixed and displayed in public places and attached to the inside or
outside of public vehicles including railway carriages for the purpose of
advertising.
In order that the said invention may be more clearly understood and carried into
offect I will proceed aided by the accompanying drawings more fully to describe the
same.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 Sheet 1 is a longitudinal section of a machine constructed according to
the present invention.
Figure 2 Sheet 1 is a plan of certain parts of the mechanism thereof.
Figure 3 Sheet 1, is an elevation of part of Figure 2.
Figure 4 Sheet 2 is a front view of the said invention.
In the several figures like parts are indicated by similar letters of reference.
With the help of the said figures I will now proceed to describe the machine
in detail.
Referring to Sheet 1 Figure 1 a a are the vanes fixed to a plato of metal b, the
said plate of metal is fixed to a shaft o which shaft is pivoted on the bridge d
and the support e. Fixed on to the shaft c is a worm which said worm engages
in the worm wheel g. The said worm wheel g is fixed to a shaft h which said
shaft is pivoted on two supports ii. On the said shaft is fixed a secondl
worin which euid worm j engages in the worm wheel A. The said worm wheel k
is fixed to a shaft 7 which said shaft is held in a support in and passes through
the support e. At the end of the said shaft is a pinion n which said pinion n
engages in the large spur-wheel o. The said spur-wheel o is fixed to a shaft p the said
shaft p being pivoted between the two supports e and e. On the said shaft p is fixed
by light spokes 9 ga light wheel r which said light wheel holds on its rim a piece
of thin boards. On each side of the thin board is displayed advertising mattor,
Openings and are made at a suitable place on each side of the machine (as
shown in section in Figure 1 and in plan in Figure 4 Sheet 2). Pieces of glass wo
and w' are inserted in the openings and t' to protect the said advertisment matter.
Further advertisments may also be displayed on each side of the machine and v².
Referring to Sheet 1 Figure 1 the action of the machine is as follows:-When
the wind or other current of air strikes the vanes a a. they rotate rapidly and
actunting the mechanism above described cause the wheel r to rotate slowly thus
causing the advertisments on each side of s to pass slowly behind the openings t
and t
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
The novelty of causing a disc wheel surface or body to be kept in motion by the
action of a wind motor wind inill wind vane or vanes for the purpose of attracting
public attention. Upon the said disc, wheel surface or body, or upon the herein-
before mentioned sections thereof is displayed pictures advertisment matter or
other information or matter for the particular purpose of directing the attention of
the public thereunto.
