PROVISIONAL SPECIFICATION.
Improved Arrangement of Apparatus for Obtaining Chromatic
Illumination from Gas or other Flame.
I JAMES OSBORN SPONG of 226 High Holborn, London, Domestic Appliances
Manufacturer, do hereby declare the nature of my said invention to be as follows:-
This invention has for object the production of novel chromatic illumination,
display or exposure of artistic embellishments, art subjects, coloured materials in
tasteful combination, such as metal or glass, plain or in prism or other form in
such manner that by specially adapted reflectors, the design device or image can
be reflected a large number of times in a single apparatus while the chromatic
appliance is rotating under the action of uprising vapour from a steady gas or
other flame.
The appliances consist of a globular or equivalent shaped body supported by
a central post and hangers capable of revolving on an agate or other centre
arranged in a branch plate projecting from a gas or other pipe from which the
light is supplied to the interior of the globe. The upper part of the post is
provided with a fan or angle bladed frame for the vapour from the flame to act
against to produce rotation the flame being vertical for direct action thereto.
The globular or other shaped body has a number of coloured glasses, lenses,
prisms, bullseye bulbs or the like suitably fitted also devices, figures, transparencies,
or advertisements which as the globe revolves are successively and repeatedly
reflected on to a concave screen composed of silvered strips arranged at various
angles in circles, each of which throw back so to speak to an observer the reflection
of the devices (some plain and some in colours) gradually merging towards and
from each other giving a very pleasing effect, coupled with that of the flame which
is also reflected in the silvered strips in bands each reflection of the flame apparently
rising out of the one below.

COMPLETE SPECIFICATION.
Improved Arrangement of Apparatus for Obtaining Chromatic
Illumination from Gas or other Flame.
1, JAMES OSBORN SPONG, of 226 High Holborn, London, Domestic Appliances
Manufacturer, 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 has for object, the production of novel chromatic illumination
display or exposure of artistic embellishments, art subjects, coloured materials in
tasteful combination, such as metal or glass, plain or in prism, or other form in
such manner that by specially adapted reflectors, the design, device, or image can
be reflected a large number of times in a single apparatus, while the chromatic
appliance is rotating under the action of uprising vapour from a steady gas, or
other flame.
The appliances consist of, and as shown in the annexed drawings, a globular or
equivalent shaped body A supported by a central post B and hangers C, C, capable
of revolving on an agate or other centre D arranged in a branch plate projecting

page_text: from a gas, or other pipe G, from which the light is supplied to the interior of the
globe A. The upper part of the post B is provided with a fan or angled bladed
frame H for the vapour from the flame to act against to produce rotation, the flame
being vertical for direct action thereto.
The globular or other shaped body has a number of coloured glasses I, I, or
they may be lenses, prisms, bullseye bulbs, or the like suitably fitted, also if
desired devices, figures, transparencies, or advertisements, which as the globe A
revolves, are successively and repeatedly reflected on to a concave screen J composed
of silvered strips K, K, arranged at various angles in circles, each of which throw
back, so to speak, to an observer, the reflection of the devices (some plain and
some in colours) gradually merging towards and from each other, giving a very
pleasing effect.
In connection with the gas flame in the globe, I may fit an electric glow lamp to
increase the brilliancy, or should an electric glow lamp alone be used in the globe,
an outside flame such as L will give sufficient uprising vapour to rotate the globe
by impinging against the fan.
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 apparatus shown in the annexed drawings acting in the manner and for
the object described.
2. The construction and employment of a freely revolving globular or other
shaped appliance provided with coloured glasses for shining from an inside light
upon strips of a reflecting concave screen and producing varying chromatic
illuminated effects, as set forth.
