Maker of Photographic Apparatus do hereby declare the nature of this invention to
be as follows:-
The camera measures 8×4 × 7, is made to carry 12 plates 4x3 ins., which are
fitted in sheaths. Inside camera are two metal plates, one on each side, which are made
to receive sheaths. The sheaths are made of metal, two of the ends being turned over
to hold plates in position. There is a thin wire fixed on the bottom of each sheath
for the purpose of threading them on metal plate in camera. Each sheath has a
catch to prevent it from falling. Inside camera at top are two small plates side by side.
These plates are moved from left to write by means of a small nob outside camera to
allow sheaths to fall. The nob goes back into position by means of a spring which
also turns a small circular metal plate, that shows the number of plates used. The
camera has a false bottom on which are two upright plates for the purpose of
receiving sheaths. The bottom can be drawn out to take plates that have been used,
without disturbing the unused ones. The shutter is made of metal, is worked by
means of spiral spring which forces a half disc to open and close lens hole. The
spring can be tightened to make shutter work faster or slower. There are two
catches: the first to hold shutter open any length of time, the other for
instantaneous exposures.
The camera has two view finders.

HENRY PRADEAU 1 Stow Road Goldhawk Road Shepherds Bush W. Maker of
Photographic Apparatus, 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 camera measures 8×4×7 is made to carry 12 plates 4×3 ins., which are
fitted in sheaths. Inside camera are two metal plates, one on each side, which are

page_text: means of a spring which also turns a small circular metal plate, that shows the
number of plates used. The camera has a false bottom on which are two upright
plates for the purpose of receiving sheaths. The bottom can be drawn out to take
plates that have been used, without disturbing the unised ones. The shutter is
made of metal, is worked by means of spiral spring which forces a half disc to open
and close lens hole. The spring can be tightened to make shutter work faster or
slower. There are two catches, the first to hold shutter open any length of time,
the other for instantaneous exposures. The camera has two view finders.
In order that my invention may be fully understood, I will now refer to the
annexed drawings in which -
Figure 1. is a side elevation showing the interior of a camera arranged according
to my invention one side of the camera being removed.
Figure 2. a perspective view of a moveable tray showing one plate and a frame
in its position after exposure.
Figure 3. underneath plan view of plate releasing mechanisin and indicator.
Figure 4. front elevation of shutter mechanism.
Referring to Figures 1, 2, 3, the plates a are carried in the carriers a' which are
formed from sheet metal or other suitable material bent as shown, so as to hold
plates in same, being provided at their lower end with a prolongation b having
projecting wires or pivots c and at their upper ends with a projection or stop piece c'.
When the plates are in their unexposed position, the plates d in the side of the
casing or body of the camera are between the bottom of the carriers al and
the wires or projections and the projection or stop piece el rests upon the
catch e carried upon the plate f which is controlled by the spring ge being a stop
piece so arranged upon the plate that upon moving saine in the direction of the
arrow, the stop piece e will release the foremost plate and allow same to fall while
the stop piece el will prevent the following plate from falling owing to its coming
into contact with the stop piece el and upon allowing the plate f to return to its
initial position the projection upon the following carriers a will engage upon the
stop piece e thus being ready to fall after exposure as the previous plate and carrier.
The projections upon the tray i are so arranged as to pass between the bottora of
the following carrier and the wires or projections aforesaid, the projections meeting
the bent ends d¹ of the plates d. By this arrangement it will be seen that the tray
carrying the exposed plates, can be removed from the camera without interfering
with the plates which are still unexposed. The indicator wheel is provided with a
series of figures or indications which may be viewed through an aperture in the casing
or body of the camera being operated by the spring pawl k upon each movement of
the sliding piece f this sliding piece being operated by a projecting part or knob !
the number of teeth upon the wheel being arranged according to the number of
indications required. The unexposed plates and carriers are maintained in position
by means of a spring or the like which may be attached to or separated from the
hinged door or flap m said spring being indicated in Fig. 1.
h
The movement of the sliding plate may be controlled by any suitable means
such as the pins n sliding in the slots n in the plate f. o is a spring for controlling
the movement of the disc j.
Referring to Figure 4, the shutter mechanism consists of a wing piece p pivoted
at p and having the projections or pins q which are attached to the spring r this
spring passing over the pulley wheels and being secured at t to the partition w.in
the body of the camera. vis an aperture in the said wing piece which in the
position shown in Figure 4, is in position with regard to the lens-so as to enable
a time exposure to be given and in the dotted lines w is in its normal closed position,
the dotted lines w¹ represent the position of this wing piece p when in its position
ready to be released in order to give a rapid exposure. The releasing of the wing
piece p is effected by operating the push piece which operates the rod y pivotally
. attached at z to the catch z¹ which is pivoted at 1 to the partition u the end 2 of
which engages in either of the notches 3 or 4 according to whether a time or rapid
exposure is required, 5 being a stop piece upon which the wing piece rests when in

page_text: its normal position. 6 is a wing or shutter which is pivotally attached at pl and has
a pin or projection y or the like, which engages with the rod 8 which passes through the
body or casing of the camera. 9 is a spring which tends to maintain the wing or
shutter 6 in the position shown in Figure 4. 10 is a stop piece or projection upon
the wing p so arranged that by operating the rod 8 the aperture is closed by the
wing or shutter 6 which engages upon same, thus bringing the wing p into position
either for a time exposure or a rapid exposure; and when the shutter has been
brought into this position the wing or shutter 6 is allowed to return to its normal
position and the wing p may then be released by operating the push piece x.
11 & 12 are the usual range finders so arranged as to be viewed either from the top
or side of the camera. 13 is a guide piece between which and the partition u the
wing piece p works.
By connecting the end of the spring r to either of the projections or pins q the
rate of movement of the wing p may be varied.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combined construction and arrangement of the various parts substantially
as described and illustrated.
2. In cameras a noveable tray having projections which engage with slides secured
to the body of the camera, and form a guide over which the carriers carrying the
plates pass after exposure, said carriers being provided with projections or pins at one
end and at the other with a projection which engages upon the stop pieces carried
upon sliding plate controlled by a spring so arranged as to permit of the
consecutive exposure of the plates, said slide piece operating a disc or wheel
which indicates the number of plates exposed, the tray being moveable as
required.
3. In shutters for cameras, a pivoted wing having an aperture being moved into
the required position for a time or rapid exposure by means of a pivoted wing or
shutter controlled by a spring and which engages upon a projection upon the
wing piece aforesaid, so that the aperture is closed while the shutter is being
brought into the required position, through the medium of a connecting rod said
shutter being controlled by a spring.
spring. A push piece which operates a releasing
catch which engages with the wing piece aforesaid, a spring or suitable con-
struction which may be placed upon one or more projections or pins upon the
wing piece so as to increase or decrease the rate of movement of the wing piece
aforesaid, the releasing catch being so arranged as to release the shutter froin the
time exposure position or the rapid exposure position.
