PROVISIONAL SPECIFICATION.
A New Means for Viewing Photographs.
I, ARTHUR CYRIL PEARSON, of 31, St. Mary's Mansions, Paddington, London,
W., Clerk in Holy Orders, M.A., do hereby declare the nature of this invention
to be as follows:.
-
This invention relates to a new means for viewing photographs and provides a
device whereby any ordinary photograph is seen in similar relief to that attained
by the use of the double photographs and lenses in a stereoscope.
In carrying the invention into effect I construct a box-like frame of any con-
venient shape, and of any material, provided with two suitable lenses. In addition
to these lenses I provide a means whereby one or other of them may be shut off,
so that the picture is then visible to one eye only, and stands out in bold relief.
The means employed may consist of a simple metal flap formed from sheet metal
or any other material pivotted or hinged so as to have a swinging movement
permitting it to rotate through an angle wide enough to cover either the right
or left haud lense as may be desired. Instead of the flap above described I may
employ a sliding shutter or any other suitable device most convenient according
to the form of the instrument.

A New Means for Viewing Photographs.
I, ARTHUR CYRIL PEARSON, of 31, St. Mary's Mansions, Paddington, London,
W., Clerk in Holy Orders, M.A., 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 relates to a new means for viewing photographs and pictures and
provides a device whereby any single photograph or picture is seen through one
lens or prism in similar relief to that attained by the use of the double photographs
and two lenses in a stereoscope.
In carrying the invention into effect I construct a box like frame of such
a shape as to fit close to the face and so form a dark chamber shielding the eyes
and provided with suitable lenses.
In addition to these lenses I provide a means whereby one or other of them
may be shut off at will so that the picture is visible to one eye only, and stands
out in bold relief. The means employed for shutting off the lens may consist of
a simple flap formed from sheet metal or other material pivotted or hinged so
•

page_text: as to have a swinging movement permitting it to cover either the right or left
hand lens as may be desired. Instead of the flap I may employ a sliding shutter,
or any other suitable device may be used for this purpose, or, where it is desired
to produce a simple and inexpensive form of instrument I may provide the box
like case or shield with only one lens through which the photo may be viewed
by either eye by simply reversing the instrument to bring the lens in front of
the eye it is desired to employ.
In order that the invention may be the better understood drawings are appended
in which a is the box like frame for excluding the light which frame is provided
with two lenses b b and has a flap c of any suitable material pivotally supported
at d in such a manner that the same may be readily swung upon its pivot and
caused to cover either the right or left hand lens and thereby permit the photo-
graph to be viewed by one eye only.
The flap above referred to may be caused to rotate by means of a milled nut
or head attached to its pivot which pivot would be extended and pass through
the case a as shown in dotted lines, the flap being attached thereto in any suitable
manner.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
A device for obtaining stereoscopic effects from single photographs or pictures
with one lens consisting of a box like frame of such shape as to fit closely to
the face and exclude the light, the said frame being provided with a lens or
lenses and a means, where two lenses are employed, for obscuring either of the
said lenses at will substantially as described and illustrated by the appended
drawings.
