THOMAS ROBERT SHELLEY Midland Railway Derby Engineer, ARTHUR
JENNINGS Lea Marston Minworth Warwickshire Farmer do hereby declare the
nature of this invention to be as follows:-
By means of utilizing existing lamps or by means of specially constructed lamp
or other artificial light a shadow sign is shewn on a pavement or other structure.
The lamp is so constructed as to send concentrated rays either from its side,
bottom or other part, ou to figures represented on a board or other object, which
has marked on it the figure or words required to be reproduced by shadow, such
figure is so marked that the reflection of light so cast is received on the pavement
or other object in the required form for properly casting the shadow so as to be
readily read or understood.
This light may also be made to act on perforated letters or figures so as to cast
the light without the return reflection.

COMPLETE SPECIFICATION.
Improvements in Signs and the like.
THOMAS ROBERT SHELLEY Midland Railway Derby, Engineer, ARTHUR
JENNINGS, Lea Marston' Minworth Warwickshire, Farmer 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 :-
as to be
The invention has for its object, the casting by shadow on the pavement wall or
other surface, any printing, writing, lettering, number or device, so
clearly understood for the purpose of advertisement in the manner hereinafter
described.
Taking as an example an ordinary lamp suspended above the pavement from the
face of the building, we propose to use any ordinary lamp as used, not interfering
with the color of glass or device that may be marked on the sides, other than the
side nearest to and facing the sign or object to be reflected, this is to be of
ordinary clear glass.
At a certain distance varying according to circumstances from the lamp and at
an angle worked out as required, is suspended an ordinary mirror or silvered glass,
on the face of which is marked the device proposed to be reflected, and such
writing or device is marked so as to read or shew inversely the same as is reflected
in a mirror of any object placed before it.
The light in the lamp preferably an electric or other strong luminant, is made to
cast its rays through the clear glass on to the mirror and the rays of light are
reflected at an angle so as to be cast on the ground, or other object as required and
so reproduce on an enlarged form, perfectly distinct even to the minutest detail
the writing, figures, or other device, so marked on the mirror, the said reflection
being shewn to the eye the right way up so as to be understood.
The silvered reflecting plate can also be utilized by being placed at an angle
and some distance from an ordinary street lamp and placed so as to reflect on an
entrance to any building or erection, name or device as desired with such sign
regulated as to size to suit requirements.

page_text: The silvered or other reflecting plate, can also be used by being acted on by the
sun, as a day sign.
We also propose to mark a window or other bright surface on a proper
back ground any name or device, inversely, which name or device is reflected on to
the ground in front by means of the sun moon or other luminant, in a form to be
readily understood.
We also propose to make any name or device of a skeleton or other shape and
suspend a distance from the light by which means the image is reproduced on the
object desired, direct without second reflection, this works independently of the
shadow reflecting sign.
'
In order to make the invention better understood reference is made to the
accompanying sheet of drawings which illustrate our improved signs, wherein
Fig. 1. shews the lamp casting its rays on the shadow sign, and the reflection
caused by such light, it also shews the light acting on the skeleton frame,
suspended for the purpose of reflection.
Fig. 2. shews a form of construction for the skeleton frame, representing figures
-desired to be reproduced.
Fig. 3. shews, front view of the silvered mirror with the word painted on
inversely, this is reproduced in its proper form by the light being cast from its
face on to the ground or other object.
In Figs. 1. and 3. a. b. a represents the mirrored sign in end view as fixed in
position and front elevation with the name marked on. c. Fig. 1 is the luminant.

Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
.claim is.
First. The use of the mirror on which is represented in figures, letters or forms,
inversely the object to be reflected.
Secondly. The use of such mirror, to throw shadows from ordinary gas, moon,
or other light substantially as described in the Specification.
Thirdly. The use of such inversely represented figures, on window or other
glass, acted on by the sun.
Fourthly. The constructing and fixing of skeleton figures or letters between the
light and object on which it is to be shewn.
