PROVISIONAL SPECIFICATION.
Improvements in or in connection with Photographic Camera
Stands.
I, ERNEST BISHOP of 188 Lewisham Road, in the County of Kent, Chemist
and Druggist, do hereby declare the nature of this invention to be as follows:-
The invention has for its object improvements in or in connection with photo-
graphic camera stands whereby an ordinary single lens camera is enabled to be used
in taking stereoscopic pictures.
For this purpose I fit to the top of a stand a sliding table or carrier to which the
camera is fixed in any suitable mauner. I provide the stand top and the slide or
carrier with suitable stops at the required distance apart. The mode of using the
apparatus is as follows. The camera is fixed to the slide or carrier and the latter
is moved sideways against one of the fixed stops, a plate is then exposed the lens is
then covered and the camera is shifted over to the other stop another plate is then
exposed and the negatives are then treated in any known manner.
Dated September 20th 1893.

DI MOLTIVATION.
Improvements in or in connection with Photographic Camera
Stands.
--
I, ERNEST BISHOP of 188 Lewisham Road in the County of Kent, Chemist
and Druggist, 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:-
The invention has for its object improvements in photographic camera stands
whereby an ordinary single lens camera is enabled to be used in taking stereoscopic
pictures.
For this purpose I fit to the top of a stand a sliding table or carrier to which the
camera is fixed in any suitable manner. I provide the stand top and the slide or
carrier with suitable stops at the required distance apart.
My invention is illustrated in the accompanying drawing in which
Figure is a front view of a camera on a tripod stand fitted with my sliding
support.
Figure 2 is a side view of the camera and end view of the sliding support
apart from the tripod stand.
Figure 3 is a front or side view and Figure + is an end view of the sliding
support separately.
a represents the camera, the legs and the head or table of the tripod stand.
The camera however instead of being fixed directly to the head or table of the
tripod stand by the screw h², as is generally the case, is attached by the screw a¹ to
a slide or carrier c mounted in guiding supports e' carried by a base or table e²
fixed to the head or table of the stand by the screw I provide the slide or
carrier c with stops at the requisite distance apart to enable the camera to be
shifted laterally the distance necessary to produce stereoscopic pictures; such stops
с

page_text: may be fixed to the slide or carrier c between the guiding supports e as shown at
Figure 1 or outside thereof as shown at Figure 3. I also preferably employ a
small bolt d as shown at Figures 1 and 4 to lock the slide or carrier c in either of
its two positions but other form of bolt or catch may be employed for such purpose
or it may even be dispensed with.
The mode of using the apparatus is as follows. The camera a is fixed to the
slide or carrier c as described and the latter is moved sideways until one of the
stops comes against a guiding support el a plate is then exposed, the lens is then
covered and the camera is shifted with the slide or carrier over to the other
stop, another plate is then exposed and the plates are then treated in any known
manner.
The two positions assumed by the camera and slide are represented at Figure 1,
the one position being shown by dotted lines the other by full lines.
It will be evident that the slide or carrier e may be constructed and mounted
differently from that herein shown and described and the stops may be differently
arranged without departing from the peculiar character of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
-claim is:
1. The improved construction of photographic camera stand substantially as
herein shown and described and for the purpose stated.
2. A photographic camera stand consisting of a slide or carrier to which the
camera is fixed, such slide or carrier being mounted in or upon guiding supports
and provided with stops, substantially as herein shown and described and for the
purpose stated.
