Improvements in or connected with Photographic Cameras.
I HERBERT GEORGE HEYBURN of 16 Upper Montagu Street in the County of
Middlesex Optician do hereby declare the nature of this invention to be as
follows:-
My invention has for its object to provide a combined camera and box or receptacle
for sensitized plates or surfaces, which is very simple in construction and not liable to
get out of order the plates or sensitized surfaces being successively discharged,
exposed, and then returned to the box in any desired order. According to my
invention I so combine the storage box with or attach it to the camera that it can be
moved relatively thereto so that either of the plates therein can be brought opposite
to a slot in the camera sufficiently wide to admit only one plate at a time therethrough
and into the guides or supports for the plate in the camera. In connection with the
storage box I use a shutter which can be brought into such a position that it leaves
only the desired one of the plates in the storage box at liberty to pass out therefrom.
The portion of this shutter which protrudes from the apparatus may be marked so
that it can readily be used as an indicator as to which of the plates is at liberty to be
passed into the camera when it is brought into line with the slot in the camera.
Whilst not limiting myself to precise details I will describe more particularly an
arrangement which will answer well in order to more clearly explain the nature of
my invention.
The apparatus consists of a box for plates or sensitized surfaces and a camera
which can be fitted up side by side so as to take up as little space as possible. This
storage box is provided with grooves or ledges to receive the plates or sensitized
surfaces. The side of this box is provided with the aforesaid shutter which 1 prefer
to be a jointed one similar in construction to the well known Venetian shutter.
This shutter is provided with an opening which admits of any plate falling through
when opposite to it. The camera may have either a rigid or sliding body or be
constructed with a bellows or in any of the ordinary or other convenient forms with
usual adjustments but without any removeable or separate back or slide. The end
opposite to where the lens is attached is provided with grooves in the position to
receive the plates or sensitized surfaces for exposure which enter through an opening
in the side next to the storage box.
Having brought the opening in the storage box shutter opposite the plate it is
desired to expose that opening is by moving the storage box brought opposite to the
slot in the side of the camera and by tilting the plate is caused to pass from the
storage box through the opening left for it by the shutter and through the slot in
the camera into the grooves for exposure in the camera. The storage box being
now returned to its normal position covers the opening in the camera and the slide
can only be returned to the box by reversing the operation. The portion of the
Venetian lid shutter that is drawn from the storage box will fold over the box and it
may be conveniently provided with a stop to regulate the position of the box itself
and to ensure the openings being brought opposite one another. The ribs of the
shutter may be numbered to indicate which plate is free to move and a handle on the
op of the box itself will enable its being easily drawn along relatively to the camera
or the withdrawal or replacement of a plate.

Improvements in or connected with Photographic Cameras.
I, HERBERT GEORGE HEYBURN of 9 Beaumont Street, Marylebone late of
16 Upper Montagu Street in the County of Middlesex, Optician, 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 has for its object to provide a simple and efficient arrangement of
combined camera and box or receptacle for plates or surfaces carrying sensitized films,
the said plates or surfaces being passed from the box or receptacle and brought
into position for exposure and after exposure being returned to the box or receptacle.
In the arrangement according to this invention this can be very readily and simply
effected without the use of parts liable to get out of order, and the plates can be
exposed in any desired order that is any one of the plates or surfaces can be brought
into position for exposure as desired, so that plates or surfaces of different descriptions
can be placed in the box or receptacle and selected for exposure as desired.
According to my invention I so combine the storage box or receptacle with, or
attach it to the camera proper that they form one combined apparatus and I so arrange
the said box or receptacle that it can be moved relatively to the camera proper so
that either of the divisions thereof in which the sensitized plates or surfaces are
situated can be brought as hereinafter described opposite to a slot in the camera proper
sufficiently wide to admit only ono plate or surface at a time and into the guides and
supports for the plate or surface in the camera proper. In connection with the
storage box or receptacle I use a shutter which can be brought into a position such as
to release either of the sensitized plates or surfaces. The portion of this shutter which
protrudes from the apparatus or some portion of the box or camera proper adjacent
thereto is marked so that it can readily be used to indicate which of the plates is at
liberty to be passed into the camera when it is brought into line with the slot in the
On the camera proper 1 place a stop and on the shutter I also place a stop
so that when the end of the shutter is adjusted to come opposite either of the plates or
surfaces to be released for exposure on the box or receptacle being drawn out when
the stops come together the said plate or surface will be opposite the slot in the camera
proper and can be passed thereinto by inverting or tilting the apparatus.
camera.
The apparatus may be enclosed in a hand bag having an opening in the bottom
through which the lens protrudes so that the band bag can be used as an ordinary
camera.
I will now more particularly describe my invention with reference to the
accompanying drawings.
Figure 1 is a longitudinal vertical section and Figures 2 and 3 are respectively a
front and a back elevation of the apparatus in the position in which it is placed when
taking a picture.
The apparatus consists of a box A divided by a partition B into two compartments
one of which C contains or constitutes the camera proper and the other contains or
constitutes guides for the box D for the sensitized plates or surfaces which box is
provided at the sides with grooves or ledges a to receive the said plates or sensitized
surfaces b. The part of this box next to the camera is provided with a sliding
shutter E which I make of a number of strips e joined together by a flexible material
after the manner of the well known "Venetian shutter." In the partition B there is
an opening F which admits of any one of the plates or surfaces 6 falling therethrough
when the box D has been moved out to bring the plate or surface opposite the
opening F and the apparatus is tilted or inverted. The camera proper ( may have
either a rigid or sliding body or be constructed with a bellows as shewn or in any
of the ordinary or other convenient forms and it may be provided with any usual
or suitable adjustments, but it requires no removable or separate back or dark slide.
The end opposite to where the lens G is attached is provided with grooves d in a
position to receive the sensitized plates or surfaces for exposure. The top portion c

page_text: of the partition 13 is provided with a stop or projecting rib f and is hinged to the
main portion so as to admit of the ready insertion and withdrawal when required of
the box D. On the inner end of the shutter E is a stop or projecting rib g which
when the box D is moved into position to discharge a plate or surface into the
5 camera proper comes into contact with the stop or projecting rib f.
When it is desired to place a sensitized plate or surface in the camera for exposure
the shutter E is withdrawn to such an extent as to uncover the edge of the sensitized
plate or surface which it is desired to expose after which the box D is drawn outwards
until the stop g on the shutter comes into contact with the stop on the partition B
and then the said plate or surface is opposite to the slot F in the partition B, and by
tilting the apparatus the said plate or surface is caused to pass from the box D through
the slot or opening F into the grooves in the camera proper. The shutter E and
box D are then returned to their normal position and then the shutter E covers the
opening F in the partition. To return the plate or surface to its proper place in the
box D the latter and also the shutter E are returned to the positions which they
occupied when the plate or surface was discharged and the apparatus being then
turned or inclined in the reverse direction the plate will pass through the opening F
into the grooves in the box D from which it was previously discharged. The portion
of the shutter that is drawn from the storage box will fold over the box and the ribs
of which the shutter E is composed may be marked or numbered as shewn to corre-
spond to the order of the plates so as to indicate which plate is liberated. A handle H
is provided at the end of the box D) to enable it to be easily drawn out. is a blade
spring which may be caused to bear on the plate or surface with greater or less
pressure to steady it by turning, by means of the knob or handle ka cam / situated
between the said blade spring and the back of the camera to which the spring is
attached.
On the back of the camera a dial and pointer may be provided as shewn at m
Figure 3 for the purpose of indicating the number of the plates which have been
used, the pointer being moved to point to a corresponding number on the dial to
the number of plate in the series last inserted in the grooved in the camera. Any
usual or suitable attachments may be used with this camera.
I is an object finder which when not in use may be slidden into the recess n so as
to be concealed from view and protected from injury. K is a focussing screw the
said screw working in a nut fixed to the front moveable portion of the camera proper
which carries the lens. For governing the exposure any known or suitable form of
shutter and means for operating the same may be employed for example as shewn at X
Fig. 2.
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. The general combination of parts constituting the portable photographic apparatus
herein before described and shewn in the accompanying drawings.
2. In photographic apparatus the combination of the camera proper provided with
guides in which slides the box or receptacle for the sensitized plates or surfaces so
that either plate or surface can be brought opposite a slot in the camera proper and a
hutter provided with a stop coming into contact with a stop on the camera proper all
rranged so that by adjusting the shutter and then moving the box relatively to the
amera proper until the said stops come into contact with each other either plate
eceptacle can be opened to the slot leading into the camera proper for discharging
nd returning either of the plates or surfaces substantially as hereinbefore described
nd shewn in the accompanying drawings.
