I, JOSEPH NEWTON WRIGHT, of High Street, Ilford, County of Essex, Chemist,
do hereby declare the nature of this invention to be as follows:-
The purport of this invention is to manufacture a photographic camera box
with a movable internal leaf adjustable and affixable by a screw or other appliance
from the back, said plate being so arranged that it can be drawn sufficiently
backwards to allow of a film or sensitised plate with its holder to be inserted
through a slit and by a forward movement of the leaf be pressed closely towards
a glass or opening in the face of the box. The inner leaf has a cutter or blade
at each of the two ends which pierce and by which a film or plate holder after
insertion can be severed ready for withdrawal through end slits of the box, the
ends of the holder projecting for that purpose.
There is also a slit at the bottom of the box to allow of the film or plate to
fall into a bag beneath, the screw or nipping appliance being moved sufficiently
for the film or plate to be released and then for a slider to be drawn backward to
allow the film or plate to drop.
The holders are in the form of envelopes, and preferably two of these are
provided for each film or plate, one envelope being partially enclosed within the
other, and the film or plate so arranged as to be centralised in the box that the
one end of each envelope projects ready to be drawn out and thereby leave the
film or plate exposed for the image.
The inner leaf has rubber or felt pads which close up the slits.
The operation is as follows:-The films in a flat condition with the envelopes
are slipped into the box, the envelopes become pierced by the blades, the closed
end of one envelope is cut off, say, the longer one, the film is pressed to the
glass, the envelopes are withdrawn separately from opposite ends, the image is
then taken, next the slider is withdrawn and the film or plate falls into the bag,
the box being then ready for a fresh envelope and film or plate for a repeat.

Improvements in or relating to Cameras and in Appliances for Holding
Films or Plates, with Means for Securing such Films or Plates in
Position, and for Facilitating the Removal of the Film or Plate
Holders.
I, JOSEPH NEWTON WRIGHT, of High Street, Ilford, County of Essex, Chemist,
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 purport of this invention, is to manufacture a photographic camera box
with a movable internal leaf adjustable and affixable by a screw or other appliance
from the back, said plate being so arranged that it can be drawn sufficiently
backwards to allow of a film or sensitised plate with its holder to be insertel
through a slit, and by a forward movement of the leaf be pressed closely towards
a glass or opening in the face of the box. The inner leaf has a cutter or blade
at each of the two ends which pierce and by which a film or plate can be retained
in position and the holder after insertion can be severed ready for withdrawal
through end slits of the box, the ends of the holder projecting for that purpose.
There is also a slit at the bottom of the box to allow of the film or plate to fall
into a bag beneath, the screw or nipping appliance being moved sufficiently
for the film or plate to be released and then for a slider to be drawn backward
to allow the film or plate to drop. The holders are in the form of envelopes, and
preferably two of these are provided for each film or plate, one envelope being
enclosed within the other; and the film or plate so arranged as to be centralised
in the box that the one end of each envelope projects ready to be drawn out and
thereby leave the film or plate exposed for the image.
The inner leaf has rubber or felt pads which close up the slits.
The operation is as follows:-The films in a flat condition with the envelopes
are slipped into the box, the leaf is moved towards the glass and in so doing
the envelopes become pierced by the blades, the closed ends of both envelopes
on one side of the box are cut or torn off, the envelopes are withdrawn
separately from opposite ends the film is pressed to the glass, the image is then
taken, the inner leaf is moved away from the glass and the slider is withdrawn
the film or plate falling into the bag, and on a complete backward movement
of the slider the box is ready for a fresh envelope and firm or plate for a repeat.
My invention will be clearly understood by reference to the annexed drawings.

Figure 2 sectional plan and Figure 3 end elevation of same.
Figure 4 front elevation.
Figure 5 represents a face view of film or sensitised plate.
Figure 6 elevation of inner envelope showing one end open.
Figure elevation of outer envelope with the line indicated for separation of
the end.
A, box or case with glass B fixed in front opening. C, back closer operable
by screw 1) from the back. E, E, pliable fillets for back closer to press against
the internal portion of box A to prevent entrance of light to the film or sensitised
plate. F, F, knife or lancet blades so fixed in box A, that the points to retain the
plate or film in position and also serve as piercers to pass through the two enve-
lopes G, H, when the back plate C is forced home by the screw D.
The cutting edges of the knife or lancet blades look in both directions and
can sever either envelope according to whether they are inserted from the right
or from the left hand side of the box A.

page_text: It is preferable to insert the envelopes with the film or sensitised plate within
them from the right hand side and with a portion of each end of the larger
envelope exposed, one exposed end, say, H¹, of which has to be cut or torn off
and with it is also cut one end of the inner envelope, say, at the line a, a, leaving
the opposite end H2 exposed to be drawn out from the side of the box A, said
envelope being severed preferably centrally along its length for its free exit when
drawn out.
The cut end G' of the inner envelope G is now left exposed and. as it is gripped
and severed centrally lengthwise and drawn out, the film or sensitised plate I
is left within the box A and close to the glass front on the further movement of
the leaf C will be pressed to glass B for the picture or image to be taken in the
ordinary way by the camera lens, all light being excluded in the manner already
described.
I purpose hanging from the camera, a flattish kind of bag, into which the
imaged film or plate can drop, such as after the withdrawal of the supporting
stud or releasing slider J.
The bag, say, of velvet or cloth, has preferably soft lead sown into its side
edges, so that it may be folded into a pocket book or satchel like order to preserve
the film or plate until ready for the ordinary developing process.
I may adopt any means for localising the film or sensitised plate in the inner
envelope, such as by pinching in the top and bottom edges and the same method
can be adopted for the outer envelope for localising the inner one.
By this invention, photograph films or sensitised plates can be prepared and
enclosed in envelopes in dozens or grosses, and in that condition carried freely to
be used as occasion may require, it being only necessary to have a box of the
kind shown on the annexed drawings for application to a camera box, or to
sufficient of the frame of one to which the lens is affixed, or by careful adjust-
ment of clipping devices on the lens frame, it can be attached to one of my boxes,
and pictures or images be taken by the rapid or slow process.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. A box A with glass face B and having a slit or slot through it from the
sides, an internal leaf operable by a screw D, a bottom slit or slot and a movable
support, the apparatus constituting a receptacle for photograph films, or sensitised
plates in the manner specified and substantially as shown on the annexed draw-
ings.
2. In connection with a box having the features set forth in the preceding
claim, the employment of two envelopes one within the other and containing
a photographic film or sensitised plate, one end of each envelope being exposed
after one end of the outer and inner envelopes have been removed by tearing
or severing, so that as the envelopes are withdrawn separately from the box, they
are respectively severed longitudinally by knife or lancet blades fixed within the
box. which blades also retain the sensitized plate or films in position all as and
for the purposes explained.
