PROVISIONAL SPECIFICATION.
A New and Improved Attachment for Taking Stereoscopic
Photographs of Still Life with a Single Camera and Lens.
I, EDWARD ANTHONY IND, of 8 Howard Street in the City of Gloucester,
Stationer's Assistant do hereby declare the nature of this invention to be as
follows:-
A square or oblong apparatus made of wood, metal or any suitable material (the
thickness of which is regulated according to the material used) with a hole through
the centre for taking a thumbscrew, or in the case of wood or any soft substance,
with a hole through the centre in which a metal thread is inserted, and a slot cut
at each end or from the side near each end, these slots to be lined with metal or
any suitable material, to strengthen them, when the apparatus is made of wood or
other soft substance.
The slots before referred to, to be from 31 inches to 5 inches apart from each
other, at equal distances from each end, or side of the apparatus as the case
may be.
By means of this apparatus the necessity of using a double set of cameras and
lenses is obviated, as by the above simple attachment, negatives of still life may
be taken, prints from which when mounted side by side in the usual manner and
viewed through the stereoscope give pictures in the most beautiful relief.
The apparatus can be easily fixed to any camera and in such a manner that it
requires no alteration of existing arrangements nor does it interfere with the
camera being used for ordinary purposes.
The way in which my attachment is used is as follows:-Screw the "attachment"
by means of the thumbscrew provided, through the centre hole on to the tripod
head, or triangle, taking care that the attachment is parallel and not at right
angles to the view to be taken, now screw the camera, by means of the thumbscrew
ordinarily used to fasten the camera to the triangle, firmly on to the attachment
through either of the slots, this is best done by fixing the screw lightly in the
thread at the bottom of the camera, then slipping it into the slot as far as it will
go and afterwards tightening it. The camera is now ready to take the first
negative. Without altering the position of the stand, the camera should now be
removed and placed in the opposite slot in the same manner, care being taken to
arrange as nearly as possible the same view on the focussing screen as in the first
negative. Negative number two may now be taken.
Prints must now be made from these negatives and mounted side by side in the
usual manner, and when viewed through the stereoscope will give a perfect
stereoscopic effect.
The sizes of the attachment and the position and sizes of the slots may vary
according to the size of the camera, and I do not bind myself to any of the sizes or
distances stated earlier in this Specification.
Dated this Seventh day of February 1895.

EDWARD ANTHONY IND of 8 Howard Street in the City of Gloucester,
Stationer's Assistant, 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:-
A square or oblong apparatus made of wood, metal or any suitable material (the
thickness of which is regulated according to the material used) with a hole through
the centre for taking an ordinary thumbscrew (B) (which is provided and forms
part of the apparatus) or in the case of wood or any soft substance, with a hole
through the centre in which a metal thread (A) is inserted, and a slot C & D cut
at each end, or from the side near the end. These slots may be lined with metal
or any suitable material if necessary, to strengthen them when the apparatus is
made of wood or other soft substance.
The slots C and D before referred to, to be from 3 to 5 inches apart from each
other at equal distances from each end or side of the apparatus as the case
may be.
By means of this apparatus the necessity of using a double set of cameras and
lenses is obviated, as by means of the above simple attachment negatives of still
life may be taken prints from which when mounted side by side in the usual
manner and viewed through the stereoscope give pictures in the most beautiful
relief.
The apparatus can be easily fixed to any camera and in such a manner that it
requires no alteration of existing arrangements nor does it interfere with the
camera being used for ordinary purposes.
The way in which my attachment is used is as follows:-
Screw the "attachment" by means of the thumbscrew (B) provided, through
the centre hole (A), on to the tripod head or triangle, taking care that the
"attachment" is parallel and not at right angles to the view to be taken. Now
screw the camera, by means of the thumbscrew ordinarily used to fasten the
camera to the triangle firmly on to the "attachment" through either of the
slots C & D (this is best done by fixing the screw lightly in the thread at
the bottom of the camera, then slipping it into the slot as far as it will go, and
afterwards tightening it). The camera is now ready to take the first negative.
Without altering the position of the stand the camera should now be removed
and placed in the opposite slot in the same manner, care being taken to arrange as
nearly as possible the same view on the focussing screen as in the first negative.
Negative number two may now be taken.
Prints must now be made from these negatives and mounted side by side in the
usual manner and when viewed through the stereoscope will give a perfect
stereoscopic effect.
The size of the attachment and the position and size of the slots may vary
according to the size of the camera, and I do not bind myself to any of the sizes or
distances stated earlier in this Specification.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The hereinbefore described attachment, fixed on an ordinary tripod head or

page_text: triangle of a camera stand in the hereinbefore described manner for the purposes
of enabling stereoscopic photographs of still life to be taken with any ordinary
camera and lens.
Dated this 31st day of October 1895.
