Improvements in Photographio Cameras.
I, JOHN GEORGE GOOSEY of 16 Blythe Hill, Catford in the County of Kent,
Engineer, do hereby declare the nature of this invention to be as follows:-
There are photographic cameras now in use which are so arranged that a series
of sensitive plates can be stored in a holder contained within the camera and simply
by rotating this holder by a handle upon an axis, which passes through to the
outside of the camera the plates can in succession be brought into position for
exposure and after exposure can be dropt on to a pile where they can safely remain
until taken out to be developed. Such cameras however have usually been so
contrived as to render it necessary that special photographic plates should be used
the edges of the photographic plates needing to be specially formed or notched to
suit the instrument.
It is an inconvenience not to be able to employ the plates commonly to be found
in the market and this inconvenience by my invention I avoid.
In my instrument the plate holder is a frame of rectangular form closed at the
bottom and having small blocks or filling pieces in the corners.
The sensitive plates are placed in this frame alternately with pieces of opaque
cardboard. The plates are somewhat wider than the cardboards and the latter are
longer than the plates so that the former extend past the corner blocks widthwise
and the latter lengthwise. The holder is provided on either side with a spring lip
and these lips so long as they are in place prevent the plates from falling out of the
holder, although they are pressed outwards by an inner bottom with a spring
beneath it with which the holder is provided.
On each end of the box there is a slide having two pins upon it which project
through slotted holes into the interior of the holder near to the mouth. The outer-
most of the cardboards retained in the holder rests on the pins. The ends of the
cardboards are notched so that a movement of the slides places the pins in such a
position that the cardboards can pass them.
The holder is mounted on trunnions within the camera and can be turned by
means of a handle which also serves to indicate the position of the holder. When
the holder is in a suitable position the outermost sensitive plate may be exposed in
the camera and a picture taken; then when the camera is closed the holder by
turning the handle is rotated through about three right angles. This movement
inverts the holder and brings fingers or projections upon or in connection with the
spring lips against cam pieces fixed within the camera; the exposed plate then falls
out on to the pile where it is to remain. Then the holder is turned in the reverse
direction through an angle less than a right angle; this motion allows the spring
lips to close upon the edges of the next plate, and also causes other stationary cam
pieces to shift the slides upon the ends of the holder. The pins in the slides are
thus brought to coincide with the notches in the uppermost cardboard and this card
is then able to fall down out of the holder and it does so fall and is deposited on
the top of the receiving pile. It then only remains to turn the holder back to its
original position and the instrument is ready to take another picture.

Improvements in Photographio Cameras.
I, JOHN GEORGE GOOSEY of 16 Blythe Hill, Catford in the County of Kent,
Engineer, 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 :——
There are photographic cameras now in use which are so arranged that a series of
sensitive plates can be stored in a holder contained within the camera and simply
by rotating this holder by a handle upon an axis, which passos through to the
outside of the camera the plates cau in succession be brought into position for
exposure and after exposure can be dropped on to a pile where they can safely
remain until taken out to be developed. Such cameras however have usually been
so contrived as to render it necessary that special photographic plates should bo
used the edges of the photographic plates needing to be specially formed or notched
to suit the instrument.
It is an inconvenience not to be able to employ the plates commonly to be found
in the market and this inconvenience by my invention I avoid.
In my instrument the plate holder is a frame of rectangular form closed at the
bottom and having small blocks or filling pieces in the corners.
The sensitive plates are placed in this frame alternatoly with pieces of opaquo
cardboard. The plates are somewhat wider than the cardboards and the latter are
longer than the plates so that the former extend past the corner blocks widthwise
and the latter lengthwise. The holder is provided on either side with a spring lip
and these lips so long as they are in place prevent the plates from falling out of the
holder, although they are pressed outwards by an inner bottom with a spring
beneath it with which the holder is provided.
On each end of the box there is a slide having two pins upon it which project
through slotted holes into the interior of the holder near to the mouth. The
outermost of the cardboards retained in the holder rests on the pins. The ends of
the cardboards are notched so that a movement of the slides places the pins in such
a position that the cardboards can pass them.
The holder is mounted on trunnions within the camera and can be turned by
means of a bandle which also serves to indicate the position of the holder. When
the holder is in a suitable position the outermost sensitive plate may be exposed in
the camera and a picture taken; then when the camera is closed the holder by
turning the handle is rotated through about three right angles. This movement
inverts the holder and brings fingers or projections upon or in connection with the
spring lips against cam pieces fixed within the camera: the exposed plate then falls
out on to the pile whero it is to remaiu. Then the holder is turned in the reverse
direction through an angle less than a right angle; this motion allows the spring
lips to close upon the edges of the next plate, and also causes other stationary cam
pieces to shift the slides upon the ends of the holder. The pins in the slides are
thus brought to coincide with the notches in the uppermost cardboard and this card
is then able to fall down out of the holder and it does so fall and is deposited on
the top of the receiving pile. It then only remains to turn the holder back to its
original position and the instrument is ready to take another picture.
In order that my said invention may be fully understood and readily carried into
effect I will proceed to describe the drawings annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a longitudinal and vertical section of a photographic camera fitted in
accordance with my invention.
Figure 2 is a tranveron contion of

page_text: Figure 3 shows the outline form of the plate holder.
Figure 4 is a side view of the plate holder together with a part of the camera
Been in section as in Figure 1 but with the plate holder in a different relative
position.
Figure 5 is a view similar to Figure 4 but again the plate holder is shown in a
different position.
is
a a are the sides or walls of the camera, bis the lens, c is the plate holder.
The plate holder has lips d d hinged to it and moveable around the joint
pins did. These lips are held in place by springs ee and when in position they
overhang the walls of the plate holder along its top and bottom edges as seen
in Figure 1. The sensitive plates are marked and the sheets which are
between them and separate them the one from the other are marked gg. The
sheets g may suitably be of cardboard, they may also obviously be of other
material, although for brevity I speak of them throughout as the "cardboards."
The plate holder opens at the back to receive the pile of sensitive plates and
cardboards and a false bottom c' and spring press the pile forwards so that
the top and bottom edges of the sensitive plate which is in front, bear against
the lips d, as is clearly seen in Figures 1 and 2; this plate is then in position
to receive an image cast upon it by the lens 6 when the lens is uncovered.
Upon the plate holder at its two ends trunnions hh are fixed, they pass light
tight through the walls of the camera and upon one of them the handle
fixed. Upon the trunnions the plates are mounted; the trunnions pass
through elongated holes in the plates, and the plates can slide endwise upon the
trunnions are pins fixed into the sliding plates and projecting through
slotted holes in the ends of the plate holder. These pins à do not protrude
sufficiently far to overlap the sensitive plates which are shorter than the
cardboards and which are kept away from the pins by the corner blocks o³ in
the plate holder. On the other hand the pins do overlap the ends of the
cardboarda g whilst by the same corner blocks c* these are kept away from the
lips d.
Im and n are pieces fixed to the sides of the camera, they are intended
to operate upon the lips d and the slides & upon the plate holder.. They do so
in the following way; after a plate has been exposed the handle i is moved at
first rearward and so on through about three quadrants. During this movement of
the plate holder the upper lip d of Figure 1 passes clear of the projection but is
caught by the projection mi when the parts arrive at the position indicated by
Figure 4; then the finger d projecting from the lip rides up the incline of the
projection m and so the lip is removed out of the way. Just previously the
shoulder on the other projection arrests the movement of the finger
the other lip d (which previously has passed clear of the projection m) and this
finger being held back whilst the plate holder completes its movement, the second
lip also is withdrawn and the sensitive plate falls out of the plate holder and is
received upon the pile in the store o. When the first plate thus escapes the
spring pushes forward the remaining plates in the holder but they cannot move
far for the pins &,, allow no cardboard to pass, these pins being in the position
in which they are represented in Figure 2. The handle i is now to be turned
a short distance in the opposite direction until the plate holder comes to the
position indicated in Figure 6. During this movement the incline n' on tho
projection n has shifted the sliding plate & so that the pins k³ now coincide with
notches g'g' formed in the cardboards. The outermost cardboard is then able
to drop out on to the pile in the store compartment o, the pins not impeding it.
The lips & are never in the way of the cardboards in consequence of the lesser
width of the cardboards as compared with that of the sensitive plates. The
lips are closed before the cardboard is dropped so that the rest of the pile in
the plate holder is retained. After dropping the cardboard it only remains to
return the plate holder to its original position and the instrument is ready for
taking another picture.
of
The projection n it will be seen by means of the inoline n? upon it, shifts the

page_text: plate twice whilst it passes from the position of Figure 1 to that of Figure 4 and
the incline n' similarly operates twice during the return of the plate holder; but
of these movements, two only serve an useful purpose viz.: the movement by which
the pins are suitably placed to retain the cardboards as the plate, holder
approaches the position of Figure. 4 and the movement by which the pins are
caused to drop the cardboard as the plate holder returns to the position shown by
Figure 5. The slides are at all times so held by the projections n that they
cannot move at improper times.
Having now particularly described and ascertained the nature of my said invon-
tion and in what manner the samo is to be performed, I declare that what I
claim is :-
1. In a photographic camera, a rotating plate holder adapted to contain a store
of rectangular photographic platos separated the one from the other by cardboards;
such plates being retained by lips on opposite sides of the plate holder whilst the
cardboards are retained by pius or projections on the other or remaining sides; and
there being also upon the plate holdor and the camera parts so arranged that on the
plate holder being rotated the lips are first withdrawn to allow the plate to fall out
and afterwards when the lips are again in place, the pins or projections are moved
BO BS to allow the cardboard to pass out.
2. In a photographic camera, a plate holder with corner blocks and containing a
pile of sensitive plates and cardboards differing in width and length and kept duly
ranged by the corner blocks and having moveable lips on opposite sides and
moveable pins or projections on the remaining sides which operate alternately to
allow the escape of the plates and cardboards one at a time from the plate holder.
3. In a photographic camera, apparatus substantially as herein described and
shown by which a series of plain rectangular plates may in succession be exposed
in the focal plane of the lens.
