PROVISIONAL SPECIFICATION.
An Improved Kaleidoscope.
ROBERT HENRY BASKETT Estate Agent 27 Eccles Road Lavender Hill
London S.W. do hereby declare the nature of this invention to be as follows:-
:-
I fix a silvered or blackened mirror at right angles of plate glass slightly
tapered and of a certain thickness. A second one I hang by a hinge with a
spring and a cord attachment which enables me to place it at any angle required.
I place a clear glass or lens at the lower end instead of the usual ground glass as
in the kaleidoscope.
Thereby I gain the power of producing endless designs from nature as in
flowers & leaves or any made article or drawings by hand suitable for all art work
or manufactures.

ROBERT HENRY BASKETT Estate Agent 27 Eccles Road Lavender Hill
London S.W. 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:-
I fix a mirror having parallel and plane polished surfaces and silvered on face or
blackened on back surface and slightly tapering in its width upon a support inside
a hollow cylinder or prism.
I hang a second of the same dimensions and material by a hinge or hinges with
a spring and cord attachment or with a screw, and graduated degrees which enables
the mirrors to be placed at any angle the one with the other that may be
required.
I place a lens of suitable focus or a piece of clear class at the lower end instead
of the usual ground and coloured glasses as in the old form of kaleidoscope. At
the eye end I place a lens of suitable focus or clear glass to keep out dust.
All reflecting mirrors are of th or th British or foreign plate glass or of
polished metal to prevent refraction of light and consequent distortion of the
design.
I use the reflecting kaleidoscope in the same way as the microscope and by
placeing underneath the lower end any natural or opaque object, such as flowers,
leaves lace jewellery engravings drawings and the like I gain the power of
producing by reflection in the arrangement of the mirrors endless designs suitable
for all art workers and manufacturers.
In the accompanying drawings it will be seen that A forms an hinge of flexible
material. B a spring screwed to a wood block. C cord. D D mirrors. E flexible
covering. F quadrant with degrees. G pointer.]

invention and in what manner the same is to be performed I declare what I

kaleidoscope also silvered surface mirrors or polished metal mirrors.
