PROVISIONAL SPECIFICATION.
Coin-operated Optical Illusion Apparatus.
I, WORTLEY WILLIAM BAGGALLY of 23, Lower Phillimore Place, Kensington,
London, W. Gentleman, do hereby declare the nature of this invention to be as
follows:-
My invention relates to coin-operated optical illusion apparatus differing
essentially in the effects obtained from any other coin-operated apparatus now in
use, the object of my invention being to both afford amusement and to excite
wonder as to the means whereby the illusion is produced.
The illusion consists in the apparent production in the air, upon a platform or
within a bottle or other transparent closed chamber of a strongly illuminated image
or representation of a figure, scene, picture, or other object, and the invention
consists in the combination, with an eye-piece provided with a transparent screen
through which the platform or the bottle or other transparent chamber may be
viewed, of a coin-operated optical lantern whereby a strongly-illuminated image is
projected upon the invisible transparent screen in such a manner as to be visible in
the air or conjointly with the platform or with the transparent chamber behind it
and to present the appearance of being actually in the air or on the platform or
contained within such transparent chamber.
The optical lantern is illuminated by an electric lamp to which the current is
supplied under the control of a coin-operated circuit-closing lever, the circuit-
closing lever being depressed by the weight of the coin and restored to its normal
position by a counterbalance which is held out of action by the spectator.
The light from the lamp diffused by a suitable screen is reflected through a
magic lantern slide and projected by a lens upon the transparent screen of the
eye-piece.
