Improvements in Photographic Cameras and in Films for use
therein.
I, JOHN FEATHERSTONEHAUGH PARSONS, of Siddington House, Kingsdown
Parade, Bristol, Artist, do hereby declare the nature of this invention to be as
follows
This invention relates to photographic cameras and to films for use therein.
According to this invention the films are arranged in a pack after the manner of a
pack of cards and are placed in a carrier inside the camera box and acted upon by
a spring tending constantly to draw the carrier towards the lens. Each film is
separate from the others and each is provided with a tongue or strap which is
extended forward to the front of the camera and made to project beyond a recess
formed at the front for the reception of the straps or tongues. The latter may
either be made in one piece with the films, or be separately made and attached to
the films.
After exposure of the foremost film it is drawn up from the pack through the
medium of the strap or tongue aforesaid and is pulled over the edge of a ledge on
which after having been drawn the film lies face downwards. The spring before
mentioned as tending to draw the carrier towards the lens advances the pack of films
so that each film is brought into focus in turn and is drawn up after exposure
as above described. Restraining strips or stops are provided for the films so that
they cannot be advanced beyond the proper focus.
The films as they are drawn out of the pack are piled one over the other on the
ledge aforesaid and can be removed at will. The chamber into which they are drawn
is light-tight.
The operator is enabled to ascertain by observing the outer ends of the straps or
tongues the number of films which have been exposed, and as each film is drawn up
the operator may sever the tongue at the recess through which it projects.

COMPLETE SPECIFICATION.
Improvements in Photographic Cameras and in Films for use
therein.
I, JOHN FEATHERSTONEHAUGH PARSONS, of Siddington House, Kingsdown
Parade, Bristol, in the County of Gloucestershire, Artist, 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 :-
My invention relates to improvements in photographic cameras and in films for
use therein.
I attain these objects by the mechanism illustrated in the accompanying drawing,

page_text: Fig. 8, is a view of the template.
Similar letters refer to similar parts throughout the several views.
"
According to this invention the films are arranged in a pack after the manner
of a pack of cards and are placed in a carrier a inside the camera box and acted
upon by a spring n in the bottom of the camera tending constantly to draw the
carrier a towards the lens. Each film is separate from the others and is attached
to a backing papers each backing paper being provided with a tongue 9 or strap
which passes through the slot in the hinged lid d, through the hinged clip h, and
over the roller f from which it is extended forward to the front of the camera and
made to project beyond a recess or slot / formed at the front for the reception of the
straps or tongues. The said straps or tongues may either be made in one piece
with the films, or be separately made and attached to the films by passing the
tongue through the slot u. The dotted line q in Fig. 1, shews the course of one
strap or tongue.
After exposure of the foremost film the operator draws out the strap attached to
it by pulling its projecting end, this liberates the said strap from the hinged clip /,
and by continuing to pull upon the strap, the film and backing paper are drawn up
from the pack, over the rollers c and f, (the said roller being supported by two
arms g actuated by the spiral spring through the medium of the strap or tongue q
aforesaid,) and are pulled over the edge of the platform or ledge von which after
having been drawn up the film and backing paper lie face downwards.
In the recess or slot I, and between the buttresses m m are piled the whole of the
tongues with a template t between each tongue, the broad end of each template
being towards the back of the camera. When the camera is charged, the straps
and templates completely fill the recess 1, thereby excluding all light from the inside
of the camera.
The normal position of the roller f when the camera is empty, is against the
underside of the guides e e fixed to the hinged lid d. When the camera is charged,
the roller rests against the underside of the lowermost strap of the pack of
unexposed films, the spring j tending constantly to press the said roller and the
arms to which it is attached upwards. The guides ee fixed to the hinged lid d
are to prevent the films touching the top of the camera while they are being
drawn up.
The spring n before mentioned as tending to draw the carrier a towards the lens
advances the pack of films so that each film is brought into focus in turn and is
drawn up after exposure as above described. Restraining straps or stops bare
provided for the films so that they cannot be advanced beyond the proper focus.
The carrier a is forced back for convenience of charging with films by a thumb
piece o situated at the bottom of the camera box, which thumb piece may be held
in position by a catch.
The films as they are drawn out of the pack are piled one over the other on the
ledge vaforesaid and can be removed at will by severing them from the straps to
which they are attached, the said straps being left in the recess 1. There is a
movable slide at the side of the camera for this purpose. The chamber into which
they are drawn is light-tight.
The operator is enabled to ascertain by observing the outer ends of the straps or
tongues the number of films which have been exposed, and as each film ris
drawn up the operator may sever the tongue 9 at the recess 1 through which it
projects.
I do not limit myself to any particular means of attaching the tongues to the
films, but the method herein described is found to be convenient.
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 :-
1. As an article of manufacture, the combination of photographic films cut in one

page_text: with the tongues or straps or the attachment of the films to backing papers or other
suitable material provided with tongues, substantially as shown and for the purpose
specified.
2. In a photographic camera, the combination of the carrier and spring for
propelling the pack of films towards the lens, substantially as described.
3. In a photographic camera, the combination of the slot through which the
tongues or straps pass and the buttresses with the templates, substantially as
described.
4. In a photographic camera, the combination of the carrier, lid with slot, clip.
arms and roller with spring, and the ledge with roller and the guides with the
camera box, substantially as shown on the drawing, for the purpose specified.
