Improvements in or relating to Photographic Cameras.
We, ARCHIBALD DUDDINGSTON WILLIS, Printer, and LUTHER WASHINGTON
MENCE, Photographer, both of Wanganui, in the Colony of New Zealand, do
hereby declare the nature of this invention to be as follows:-
-
This invention relates to cameras used for taking photographs, and more
particularly to that class of camera by which the different parts of a sensitized
plate may be exposed consecutively.
We are aware that cameras have been made to utilize one portion of a sensitized
plate for one position of an object, and another portion for another position, or
that one view has been produced on one portion of a plate and another view on
another portion, and that when the plate has been fully utilized, all the views
contained thereon have been developed at one operation, and prints of all-the
views taken from the negative plate at one time.
The devices used with such cameras were, however, expensive and intricate.
According to our invention the apparatus is simplified the operation of taking
the photographs rendered facile, and the possibility of taking the different views
in rapid succession is assured.
We prefer to use an ordinary square shaped camera, though other kinds may
be adapted for our purpose, and we divide the interior vertically and horizontally
or otherwise so that longitudinal tubes are formed which extend from the front
to the back of the camera, or a part of such distance. The ordinary focussing
screen, plate holder, and lens, are employed, or films may be used, but we mount
the lens on a short length of tubing which will fit freely into the tubes of the
The interior of this short length of tubing, and of the longitudinal
tubes, are coated with lamp black or other ordinary material. Around the end
of the camera and covering the front of the same we fix a loose bag so that it
is light proof and we make the same of any suitable textile material which
is impervious to light. A hole is cut near the centre of this cloth and the front
of the lens passed through the same and so fastened as to be light proof.
camera.
The tubes may be made telescopic and capable of sliding in other tubes in
order to obtain a correct focal distance between the lens and the glass screen as
required for different views or subjects.
In taking photographs the lens is" applied to one of the tubes and an exposure.
effected by removing the cap or operating a shutter in the ordinary way. The
cap or shutter is replaced and the lens applied to another of the tubes for a
second exposure, the operations being thus repeated until the lens has been
applied to all the tubes.
By removing the tubes the camera can be used as an ordinary camera and a
photograph taken which will cover the whole plate.

MENCE, Photographer, both of Wanganui, in the Colony of New Zealand, 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
more
cameras for taking photographs, and
particularly to that class of camera by which the different parts of a sensitized
plate may be exposed consecutively.
We are aware that cameras have been made to utilize one portion of a sensitized
plate for one position of an object, and another portion for another position, or
that one view has been produced on one portion of a plate and another view on
another portion, and that when the plate has been fully utilized, all the views
contained thereon have been developed at one operation, and prints of all the
views taken from the negative plate at one time.
The devices used with such cameras were, however, expensive and intricate.
According to our invention the apparatus is simplified the operation of taking
the photograph rendered facile, and the possibility of taking the different views
in rapid succession is assured.
We prefer to use an ordinary square shaped camera, though other kinds may
be adapted for our purpose, and we divide the interior vertically and horizontally
or otherwise so that longitudinal tubes are formed which extend from the front
to the back of the camera, or a part of such distance. The ordinary focussing
screen, plate holder, and lens, are employed, or films may be used, but we mount
the lens on a short length of tubing which will fit freely into the tubes of the
camera. The interior of this short length of tubing, and of the longitudinal
tubes are coated with lamp black or other ordinary material. Around the end
of the camera and covering the front of the same we fix a loose bag so that it
is light proof and we make the same of any suitable textile material which
is impervious to light. A hole is cut near the centre of this cloth and the front
of the lens passed through the same and so fastened as to be light proof.
The tubes may be made telescopic and capable of sliding in other tubes in
order to obtain a correct focal distance between the lens and the glass screen as
required for different views or subjects.
In taking photographs the lens is applied to one of the tubes and an exposure
effected by removing the cap or operating a shutter in the ordinary way. The
cap or shutter is replaced and the lens applied to another of the tubes for a
second exposure, the operation being thus repeated until the lens has been
applied to all the tubes.
By removing the tubes the camera can be used as an ordinary camera and a
photograph taken which will cover the whole plate.
The accompanying drawing illustrates the invention.
Figure 1 is a front view of the camera with the lens and covering removed.
Figure is a longitudinal section of the camera.
Similar figures of reference indicate corresponding parts.
(1) is a camera with its front removed and shewn on the drawing square
shaped, (2) are the tubes which may be made of tinplate, light wood, vulcanite,
or other suitable material coated with lampblack, (3) is the tube containing the
lens, (4) the extensible covers made light proof upon the camera and the tube (2)
by elastic rings (5) or by other suitable means, (i) is the focussing screen.

page_text: The lens tube (3) is mounted upon a short length of tubing (7) which is made
to fit the tubes (2) and may be readily removed from one tube (2) to another..
In using our invention an exposure is effected with the tube (7) in any of
the tubes (2), the said tube (7) is then moved into another tube (2) for a fresh
exposure and so on until the whole divided interior has been exposed. The
cover (4) excludes the light during the removal of the said tube (7).
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. In a photographic camera, the combination of tubes (2), the lens tube and
the cover made light proof to the camera and the lens tube, substantially as set
forth.
2. A photographic camera provided with tubes extending longitudinally from
the front towards the back, in combination with a lens tube having a length of
tubing to fit the aforesaid longitudinal tubes, and a cover made light proof upon
the camera and the lens tube, substantially as set forth.
3. The general construction of photographic cameras, consisting of parts con-
structed and arranged substantially as set forth.
