PROVISIONAL SPECIFICATION.
An Improved Means for Advertising.
ARTHUR CHAMPNESS 1 Stockfield Road Tulse Hill Surrey Clerk do hereby declare
the nature of this invention to be as follows :--
The object of this invention is to advertise on water, either in its denser forms, as
the sea, rivers, streams, or pools, &c. or in the form of vapour as steam, fog, mist, or
clouds in its various forms and is performed as follows:-
By the aid of a long focussed magic lantern, with a powerful light (such as the lime
or the electric light) the advertisement which is designed on the slide can be thrown
on the water or vapour which acts as a screen and when focussed a perfectly clear
and legible advertisement appears upon the water or vapour.
The especial novelty I claim is :-
The use of the magic lantern to produce illuminated advertisements on water either
in a vapourous or dense form as herein before described.
Dated this Third day of February 1890.

COMPLETE SPECIFICATION.
An Improved Means for Advertising.
ARTHUR CHAMPNESS 1 Stockfield Road Tulse Hill Surrey Clerk do hereby declare
the nature of this invention and in what manner the same is to be performed, to
he particularly described and ascertained in and by the following statement:-
The object of this invention is to advertise on water either in its dense forms as the
sea, rivers, streams, pools &c. or in the form of vapour as steam, mist or clouds in
their various forms viz. cirrus, cumulus, nimbus and stratus and is performed as
follows:-
For water in its denser forms I use a lantern constructed as shown in Fig. 1
which is a powerful magic lantern lighted with the electric light. In cases where the
water is situated so that the lantern can be brought to within a short distance of it,
the lime light or even a lamp may be substituted so that the lantern may remain
stationary and the advertisement thrown on any spot that may be desired. I place a
plane mirror in front of the lantern (by any suitable rods and joints that will allow of
its being moved in any position required) and reflect the advertisement on to the
surface of the water. The slide used can be either painted on glass or any other
transparent substance or a stencil plate may be used, the latter producing a much
better effect, now the lantern being placed in position and the slide inserted the
rays of light are reflected by the mirror on to the surface of the water, the molecules
of water reflect sufficient light to form a perfectly clear and legible advertisement on
the surface of the water.
For water in the form of vapour for instance the clouds, I detach the front portion
of the lantern Fig. 2, and remove the mirror further away from the lantern, the
distance being varied according to the subject dealt with. The slide best suited is a
stencil plate of the same size as the mirror, and laid upon the mirror, but some good
effects may be produced by placing it a short distance from the mirror and nearer the
lantern. The light from the lantern being thrown upon the mirror is reflected off in
a pencil of light on to the cloud which it lights up on that portion on which the
pencil of light strikes, if this pencil of light is composed of the rays A A, B B, CC,
DD, E E, then the cloud will be lighted up by the reflected rays a a, bb, cc, dd, ee,
but if a stencil be placed on the mirror so as to prevent the rays B B, C C, D D,
D

page_text: being reflected then only the rays a a, e e, will light up the cloud and by darkening
the mirror and only allowing it to reflect the rays in the form of a letter as in Fig. 3,
then the cloud will be lighted in the form of that letter and by making a combination
of letters a luminous advertisement can be placed on the clouds.
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
The production of illuminated advertisements, writing or images on water in its
various forms, as the sea, rivers, streams pools, steam, mist or cloud by means of the
principles involved in the foregoing Specification.
Dated this 18th day of October 1890.
