PROVISIONAL SPECIFICATION.
Improvements in the Use of Incandescent Electric Lights.
1, CHARLES WELLS, of 115, Great Titchfield Street, in the County of Middlesex,
Gentleman, do hereby declare the nature of this invention to be as follows:-
According to my invention, I attach or fix incandescent electric lamps to the ends of
radial arms, or on a disc, to which a rapid revolving motion is given.
Each lamp instead of forming a speck of light, produces a circle of light, the
diameter of which is proportional to the distance of the lamp from the centre.
The motion is preferably given by means of an electric motor.
Dated this 12th day of September 1888.

COMPLETE SPECIFICATION.
Improvements in the Use of Incandescent Electric Lights.
I, CHARLES WELLS, of No. 115, Great Titchfield Street, in the County of Middlesex,
Gentleman, 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:--
According to my invention, I attach or fix incandescent electric lamps to the end
of radial arms, or on a disc, to which a rapid revolving motion is given.
Each lamp, instead of forming a speck of light, produces a circle of light, the
diameter of which is proportional to the distance of the lamp from the centre.
The motion is preferably given by means of an electric motor.
In order that my invention, and the best means of carrying the same into practical
effect, may be thoroughly understood, I will now proceed to describe the same,
referring in so doing to the accompanying drawing which is to be taken as part of
this specification and read therewith.
Fig. 1 is a front elevation illustrating the arrangement of three incandescent lamps
on the respective outer ends of that number of arms.
Fig. 2 is a side elevation illustrating one form of mechanism for carrying my
invention into effect.
A, B, C are three lamps; and a, b, c, the arms all adapted to be revolved at
different distances about a common centre d. I do not confine myself to using radial
arms, as the lamps may be supported upon a disc, or frame work, adapted to hold and
carry them at different distances from and about a common centre.
D is a shaft from which the arms A, B, C radiate. It is supported in suitable
bearings, and proper provision is made for its being rotated at a proper speed. The
figure shows a grooved belt pulley E, but I prefer to use an electric motor.
The current is supplied to the filaments in the lamps in any convenient way. I do
not confine myself to the one illustrated, as any electrical engineer will understand
how the current can be supplied to the filaments.
I do not confine myself to the number of lamps, nor to their being all in one plane.
Mechanism such as I have described may be duplicated, and adapted to revolve the
lamps in different directions.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
A series of incandescent lamps supported at different distances from a common
centre and means for revolving them about such centre as set forth.
