PROVISIONAL SPECIFICATION.
An Improved Photographic Magazine Camera and Appliances used
therewith.
HERBERT JAMES TEAR of 12 Clapham Road Stockwell in the County of
Surrey and ARTHUR LEWIS ADAMS of 81 Aldersgate Street in the City of
London, Manufacturer of Photographic Apparatus do hereby declare the nature
of this invention to be as follows:-
Our invention consists in providing a simple and effective form of magazine
camera by which dry plates or other sensitive surfaces used in photography may
be stored for use, and each brought into the position in which it is necessarily held
opposite the lens during exposure, afterwards, being removed into a seperate
recepticle, allowing a fresh plate or other sensitive surface to be brought into
position.
We construct the camera preferably of an oblong rectangular form, in the front
end of which is placed the lens and in connection therewith, we use a weighted shutter
moving upon an axis and operated upon by levers with suitable attachments.
The end of the case or camera is divided into two parts horizontally, the upper
compartment forming a recepticle for the sensitive plates or surfaces previous to
exposure and the lower portion of the same after exposure.
The upper compartment contains a sliding partition placed behind the plate and
acted upon by a spring which is regulated by means of a cord or .other convenient
attachment passing through the camera.
The plates are held in position by the spring forcing them against projections in
the body of the camera. On the pressure of the spring being released, one of the
plates falls upon a hinged shelf which is capable of being raised by means of a
lever beneath it acted upon by means of a cord or other suitable attachment, and
the plate then slides into the lower compartment.
Glazed non-actinic paper or other convenient material is applied to the back of
each sensitive or transparent surface-and when flexible films are used a rigid
substance, preferably glazed, is prepared on one side with a suitable adhesive
material.

An Improved Photographic Magazine Camera and Appliances used

I HERBERT JAMES TEAR of 12 Clapham Road Stockwell in the County of
Surrey and ARTHUR LEWIS ADAMS of 81 Aldersgate Street in the City of
London Manufacturer 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:-
This invention relates to an improved photographic magazine camera and
appliances used therewith and our said invention is designed to produce an
economical simple and effective form of magazine camera by means of which dry
plates or other sensitive surfaces used in photography may be stored for use and
each successively brought into the position in which it is required to be held during
exposure afterwards being removed into a separate receptacle allowing a fresh or
other sensitive surface to be brought into position-all these changing operations
and the storing receptacles or reservoirs being entirely within the camera case.
We construct the camera advantageously of an oblong rectangular form in the

page_text: front end of which is placed the lens and in connection therewith we use any
suitable shutter for instance a weighted shutter moving upon an axis and operated
upon by levers or suitable attachments.
The end of the case or camera is divided into two parts horizontally the upper
compartment forms a receptacle for the sensitive plates or surfaces previous to
exposure. The upper compartment contains a movable part or sliding partition
placed behind the plates and acted upon by a spring or springs which is regulated
by means of a cord or other convenient attachment passing through the camera
case advantageously out, at the back. The plates are held in position by the
spring pressing the said sliding part and forcing them against projections in the
body of the camera the front plate having no platform or support under its bottom
edge on the pressure of the spring being released such front or foremost plate falls
upon a hinged plate or shelf which is capable of being raised by means of a lever
beneath it being acted upon by means of a cord or other suitable attachment and
the sensitive plate then slides into a lower compartment or storing reservoir.
Glazed non-actinic paper or other convenient material or a sheath is applied to
the back of each sensitive (or transparent) surface or same may be mounted or
protected in any suitable manner.
When flexible films are used a rigid substance advantageously glazed is prepared
on one side with a suitable adhesive material.
And in order that our present invention may be fully understood and readily
carried into practice we will proceed to further describe same with reference to
the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a sectional side elevation on line 1-1 Figure 3.
Figure 2 is an end elevation looking at the lens or "front" of the camera-the
upper part of the casing being broken out to show interior at line 2-2 Figures 1
and 3.
Figure 3 is a horizontal longitudinal section on the line 3-3 Figure 1.
Figure 4 is a vertical transverse section on line 4-4 Figure 3-looking from
the back of the camera..
Similar letters of reference indicate corresponding parts throughout.
a is the camera case and b the lens. c is a sliding partition or slide which is pushed
constantly in the direction of the lens by the strong spring d and so presses the
series of sensitive plates or films e against the lugs or projections of which latter
extend only partially down each side on the inside of the camera case a as shown
in Figures 1 and 2.
g is a string (or it may be a wire or rod) with a ring g' (or other suitable
gripping device) on the end thereof by means of which the slide c can be pulled
back in the direction of the arrows a Figures 1 and 3.
g
By this string the slide c is drawn back and the sensitive plates e can then be
filled into the space in front of c through an aperture in the top closed by the light
tight lid or cover / Figure 1 and these said plates rest on the support or floor i
Figure 1.
The slide c is then released and forces the series of plate e toward and against
the projections and the front plates ex is there arrested and ready for exposure
being supported only by the pressure against f as it no longer rests on i.
"
After exposure the slide c is pulled back by the string g sufficiently to take the
pressure off ex which then instantly falls down to the bottom of the camera and lies
in the position shown at e¹ Figure 1 on the "raiser " or appliance m hereinafter
explained meantime on releasing string the slide e pushes forward the remaining
plates e and the plate previously next behind ex now becomes the front plate and
is brought up to register ready for exposure (as before with e*) its bottom edge
being clear of i.
To follow the fallen plate e* :-
The plate in the position e¹ (Figure 1) is now raised up (to a horizontal position

page_text: in line with the opening y) by means of pulling down the cord or connection n (in
the direction of the arrow Figure 3) which pulls down one end of the lever o this
latter turns on the axis or fulcrum o¹ and thus causes the other end of o to raise up
the hinge plate or "raiser" m which turns on its hinge or axis m².
The plate e thus raised up assumes the position el shown in dotted lines.
(Figure 1) and the whole camera is now tilted backwards and the plate then slides
off the raiser m through the aperture y as shown at e¹¹ and then finally falls and
lays flat in the bottom part of the exposed plate reservoirs as shown at e**
Figures 1 and 4.
From this reservoir or store chambers the exposed plates are afterwards
removed (in the dark chamber) through the light tight door or covering t for
developement et cetera.
Thus the camera being charged with a stock of sensitive plates or films (in
suitable sheaths or otherwise suitably arranged) the whole of same can be carried
exposed successively changed and stored in the reservoirs after exposure without
having to open the camera and in a very simple expeditious and effective
manner.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. Photographic magazine cameras in which the front plate or sensitive surface
is held in position for exposure by means alone of suitable spring pressure from
behind forcing same against side lugs or projections on the inside of the camera
case said front plate being quite clear of the supporting floor and having nothing
beneath it to support same so that when said pressure is momentarily withdrawn
said front plate readily drops and is transferred to the store chamber or reservoir
for exposed plates substantially as and for the purposes set forth.
2. In photographic magazine cameras I claim the combination of the short side
lugs or projections such as with a support i (which does not extend under the
front plate of the series) and the sliding part such as c operated by a suitable
spring or springs and operating in a reservoir chamber or division for holding the
unexposed plates substantially in the manner and for the purposes hereinbefore
described and illustrated in the drawings hereunto annexed.
3. In photographic magazine cameras I claim the "raising" mechanism such
as m n o in combination with and acting in conjunction with the mechanism
or apparatus claimed in above claim No. 2 substantially in the manner and for
the purposes hereinbefore described and illustrated in the drawings hereunto
annexed.
4. A photographic magazine camera having a reservoir or store chamber in the
upper part of the back end of same and a sliding partition in said chamber
operated by a spring and controlled by a cord or the like extending through the
back short lugs
or projections on the inside of the camera case which allow the
plate or sensitive surface to fall forward beneath same on to the "raiser" mechanism
a hinge plate operated by a lever and grip appliance arranged in the bottom part
of said camera case and a second reservoir or store chamber for the exposed plates
this latter chamber being arranged beneath the first named chamber and having
a narrow slit near the top of same to permit the exposed plates et cetera to be
passed into same therethrough substantially as and for the purposes hereinbefore
set forth.
