COMPLETE SPECIFICATION.
Improvements in Pocket, Hand, or other Photographic Cameras.
We, JOHN WILKINSON and ALFRED WILKINSON, both of St. Oswald Street,
Manchester, in the County of Lancaster, Photographic Material Manufacturers,
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 an improvement in pocket, band, or other photographic
cameras.
The object of this invention is to obtain a maximum size of exposed plate with a
minimum size of camera.
We effect this object by the means hereinafter described and as shown in the
accompanying sheet of drawings in which
Fig. 1 represents a side view, and Fig. 2 a longitudinal section of a photographic
camera constructed according to our said invention :
Fig. 3 is a complete end view, and Fig. 4 is also an end view of the same camera
with the back removed.
Fig. 5 is a front view and Figs. 6 and 7 are sectional edge views of that portion
which constitutes the back of the camera otherwise the dark slide.
In these views similar letters refer to similar parts.
In this invention the body a of the camera may be either of the form shown on
the drawing or of other preferred form.
In order to obtain a maximum size of exposed plate with a minimum size of
camera, we construct the back of said camera with a rebate as b shown in Figs. 2
and 4: In place of the ordinary back we substitute therefor a dark slide as c
Figs. 1, 2, 3, 5, and 6, which we construct so that the aforesaid rebate b fit
may
within the frame d of the dark slide: Said dark slide is retained when in the
position shown in Figs. 1 and 2 by means of spring clips as e or other equivalent
fasteners which may be readily disengaged after a picture has been taken and the
dark slide reversed and retained by the same means.
In a modification of our invention we form the dark slide with a rebate as b
hereinbefore described to fit into a corresponding recess within the camera body,
or to fit on the camera body as in Fig. 7.
We desire it to be understood that we do not claim as our invention the
substitution of a dark slide for the ordinary back of a photographic camera, but,
Having now particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1st. In a pocket, hand, or other photographic camera, the construction of the
back of said camera with a rebate as b on which to fit the frame of a dark slide as c
said dark slide being retained in position either by spring clips as e or other
equivalents substantially as described.
2nd. In a pocket, hand, or other photographic camera, the construction of a recess
around the back of said camera in which to fit a rebate as b formed on the back of
a dark slide as c, said dark slide being retained in position either by spring clips
as e or other equivalents substantially as described."

the manner substantially as herein before described.
4th. In a pocket, hand, or other photographic camera the means for obtaining a
maximum size of exposed plate with a minimum size of camera substantially as
herein before described.
