A New or Improved Apparatus for Producing Vari-coloured Effects
with Illuminated Advertisements or the like.
We, ARTHUR JOSEPH PARSONS, of 10, Dunster Gardens, Brondesbury, London,
Electrical Engineer, and CHARLES ORME BASTIAN, of 8A, Manchester Square,
London, Electrical Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention consists in so arranging a moving or movable transparent or
semi-transparent multi-coloured screen or screens or surface or surfaces between
any suitable source of light and a ground glass- or opaque or other suitable sur-
face bearing the advertisement or other matter or thing to be displayed by
illumination and providing a motor or means to revolve or otherwise cause said
multi-coloured screen etc. to travel or move in suchwise that the colouring effect
is continually varying or changing into different colours or blends.
For this purpose we may use an endless band or sheet of calico or other suit-
able flexible material passing around two or more rollers by which latter said
band is caused to travel round and round or reciprocated by any suitable means
such as an electric motor or clockwork or by hand.
This band is or may be divided into six equal divisions coloured with the
three primary colours regularly allotted to the aforesaid spaces each colour being
advantageously shaded off or graduated-for instance with the colour deepest
at the middle of each division respectively.
Thus as the screen revolves and say the two divisions of red coincide in position
between the light and the advertisement consequently the light passing through
both the red divisions will show the advertisement with a strong red light while
as the band or apron moves round thereupon varying blend of colours is shown
until the next two colours (say blue) coincide between the light and the adver-
tisement whereupon a strong blue light is shown and so on.
In place of a travelling endless apron or band as aforesaid to provide two oppo-
sitely moving coloured surfaces according to the present invention two concentric
revolving discs or one or more revolving drums or cylinders coloured in any
desired manner may be used in combination with the herein before described
ground glass etc. bearing the advertisement etc. to be displayed.

with Illuminated Advertisements or the like.
We, ARTHUR JOSEPH PARSONS, of 10, Dunster Gardens, Brondesbury, London,
Electrical Engineer, and CHARLES ORME BASTIAN, of 8A, Manchester Square,
London, Electrical Engineer, 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 consists in so arranging a moving or movable translucent multi-
coloured screen or screens or surface or surfaces between any suitable source
of light and a ground glass or translucent or other suitable surface advantageously
bearing the advertisement or other matter or thing to be displayed by illumina-
tion and providing a motor or means to revolve or otherwise cause said multi-
coloured screen etc. to travel or move in suchwise that the colouring effect is
continually varying or changing into different colours or blends.
For this purpose we may use an endless band or sheet of muslin or other suit-
ble flexible translucent material passing around two or more rollers by which
latter said band is caused to travel round and round or reciprocated by any suit-
able means such as an electric motor or clockwork or by hand.
This band is or may be divided into six divisions (advantageously equal)
coloured with the three primary colours or other suitable colours regularly allotted
(in regular order) to the aforesaid spaces each colour being advantageously
shaded off or graduated--for instance with the colour deepest at the middle of
each division respectively.
Thus as the screen revolves and say the two divisions of red coincide in position
between the light and the advertisement consequently the light passing through
both the red divisions will show the advertisement with a strong red light while
as the band or apron moves round thereupon varying blend of colours is shown
until the next two colours (say blue) coincide between the light and the adver-
tisement whereupon a strong blue light is shown and so on.
In place of a travelling endless apron or band as aforesaid to provide two
oppositely moving coloured surfaces according to the present invention--two con-
centric revolving translucent discs or one or more revolving translucent drums or
cylinders coloured in any desired manner may be used in combination with the
herein before described ground glass etc. bearing the advertisement etc. to be
displayed.
Referring to the accompanying drawings:-
--
Fig. 1 is view in front elevation, Fig. 2 is plan, and Fig. 3 a cross sectional
view on line 3-3 Fig. 1 of an apparatus according to our present invention said
apparatus being shown in a box or casing A which latter however can be dis-
pensed with if desired.
A is main case containing the coloured endless band or sheet a.
B is small case or casing attached to A and containing the motor by which
the said endless band a is revolved--the said motor in the case illustrated being
an ordinary spring motor or clockwork which latter forms no part separately of
our present invention but any other suitable motor may be employed to slowly
revolve the band a as hereinafter described.
is the top roller and b¹ the lower roller on which the endless band a is mounted
and by which motion is imparted to the latter the top roller & being provided
with a toothed wheel y thereon which meshes with the last or one of the train
of wheels of the motor. Each roller is shown provided at each end with
sprocket wheels or teeth 6* and the coloured endless band a is provided along each

rollers bb.
Or the band a may be attached to a sprocket chain or chains.
c is the front or surface bearing the advertisement-this front e being formed
of ground glass or other suitable translucent material; or the advertisement may
be on a clear glass front e in which case we insert a ground glass or translucent
surface between the coloured band and the front c.

being the
Thus when motion is imparted to the endless band a between the lights and
the translucent surface c (or c* as the case may be) a very novel and striking
colouring and blending effect will be produced.
Or instead of the foregoing arrangement of coloured endless band a we may
employ 2 circular plates or discs of translucent material arranged to revolve in
opposite directions one behind the other as shown in Fig. 4 and each coloured
in regular order for instance each with 3 colours as shown in Fig. 5; or we
may employ 2 translucent cylinders or drums one arranged within the other
with the light d in the interior thereof as shown in Fig. 6 and the colours arranged
on same as before described or we may employ a single translucent drum as shown
in Fig. 7 divided into six divisions as with the band a said drum being arranged
between the light and the translucent screen or front c or c*said discs or drum
being of course formed of any translucent material suitable for the purpose.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed we declare that what we
claim is:-
1. In apparatus for showing vari-coloured illuminated advertisements―the
combination of two oppositely moving translucent coloured surfaces arranged
and moving between the source of light and a ground glass or translucent screen
the latter having the advertisement thereon or adjacent thereto substantially as
and for the purposes herein before described.
2. The herein-described improved apparatus for producing vari-coloured effects
with illuminated advertisements or the like the several parts being combined
and arranged to act substantially in the manner hereinbefore set forth and illus-
trated in the drawings hereunto annexed.
