COMPLETE SPECIFICATION.
A Novel Method of Producing a Variety of Chromatic Effects for
Advertising or other Purposes.
I, JOHN JAMES JONES, of 3 Norton Terrace, Cannhall Road, Leytonstone, Essex,
Artist, 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 is for the purpose of producing a variety of chromatic effects by
means of a revolving transparent, or semi transparent disc or discs, the disc or discs
are made to revolve at the back of a picture or design that is cut out, or perforated,
or punched out, so that the said disc or discs revolving at the back of the picture
or design produces the effects claimed by me. I use artificial light or daylight
at the back of the disc or discs to obtain the required effects, and revolve the disc or
discs by any approved motor, such as clockwork, electricity, hot air, cold air, water,
steam, or a fan. 1 may, if desirable, enclose the apparatus in a box.
The manner of carrying the foregoing invention into practice is shown on the
annexed drawings.
Figure 1 is a front elevation of a fixed opaque screen with a device punched out, or
perforated in disc form, leaving hollows, through which reflected light from the back
passes to make the picture or device of a plain readable character.
Figure 2 is an elevation of a revolving disc of transparent or semi-transparent
material, with scroll, or curved lines from the centre to the periphery and with fillings
in of various colours, indicated by the various shadings on the drawing to impart a
chromatic effect to the device in the front screen.
Figure 3 is an elevation of a revolving black and openworked disc to be used for
producing chromatic effect in viewing the device of the front screen by the
back light.
Figure 4 represents a box A with a fixed screen B suitably deviced, say as at
Figure 1 in the front thereof.
Cis the revolving disc, such as at Figures 2 or 3, this is on an axle D rotatable by
clock gear E (or otherwise) fitted in the box A.
F is an incandescent electric lamp, and G a reflector for concentrating the light
upon the disc, so that the device upon or in the front screen can be readily observed.

page_text: 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 :-
1. The novel method of and appliances for producing a variety of chromatic effects
for advertising, or other purposes, as described.
2. The combination of a deviced fixed front screen and a revolving back disc, as
described for the purposes set forth..
