I JULES FRANÇOIS GEORGE DE GEOFROY of 10 Rue Matignon, Paris, in the Republic
of France, do hereby declare the nature of this invention to be as follows:-
This invention relates to that part of photographic apparatus of the hand camera
order, in which the plates are held, and which is termed the magazine, the object of
the invention being to so construct this magazine that the distance of the sensitive
plate from the objective shall be constant, the sensitive plates, after the picture is
taken, being returned to the magazine, instead of the plates being piled one on the
top of the other.―
In carrying out this invention, a sliding frame, constituting a kind of drawer for
carrying the plates, is used, means being provided for pulling this drawer forward,
and pushing it back, as required.-The plates are secured in metal frames, which are
placed in the drawer, and are pressed upwards by springs suitably held in grooves in
the hottom of the camera.—
The front wall of the drawer has openings top and bottom, to allow for the passage
of the plates.
Suppose the drawer being full of plates, and it is desired to use one, the drawer is
drawn forward, so that the top plate passes some stops. As the draw is pushed back,
the plate is held by the stops, and when the drawer is in its normal position, the
plate falls to the hottom of the camera, where it is held securely by magnets
arranged in the bottom of the camera, in the proper position to take a picture.―
When a fresh plate is desired, the drawer is again drawn forward, so that the top
plate will be held by the stops, ready to fall to the bottom of the camera, when the
drawer is pushed back.―
As the drawer is pulled forward, the used plate enters the box, and takes its place
at the bottom of the pile, leaving the bottom of the camera free to receive the fresh
plate, the frame of which will be held by the magnets, as before.―
In this way, every time the drawer is pulled out and pushed in, the used plate
will be withdrawn, and the fresh plate will take its place at the proper distance from
the objective.

I JULES FRANÇOIS GEORGE DE GEOFROY of 10 Rue Matignon, Paris in the Republic
of France, 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 present invention relates to a special an improved construction of magazine
Arrangement for photographic apparatus.—
In the accompanying drawing, a photographic apparatus provided with the this
new system-of magazine is shown, Fig: 1 being a longitudinal section, and Fig: 2 in
a horizontal section of the same.
It should be understood that my invention only relates to the magazine, and not
to the other parts of the apparatus, which can be of any suitable construction.
The magazine consists of a drawer a, in which are placed, in the ordinary way,
metal frames b b b, in which are held the sensitive plates. It enn-be-moved-into-a
mee-formed at the back-of-the-dark-chamber by: The drawer is fitted in a box c,
which is fixed or removable-(in the Intter case, it is provided with a sereen or shatter).
This box-in of such dimensions that, besides the necessary space in I in the optical
axis of the objective, for lodging the plate to be exposed, there is besides sufficient
space in II to receive the drawer a. This-drawer which may be moved so as to be
drawn either into the position I or the position II.-One or two rods & d, which are
fixed to the drawer, and which terminate in the ringe on the exterior of the box c,
permit of this operation being performed.―
The side of this drawer, which also forms one of the walls of the dark chamber
proper, is of a height equal to the total thickness of all the plate frames, less, at each
end, the portion necessary to allow of the passage of the end or top and bottom
plates.
Upon the bottom g of the box e Care fixed, in the part II of the magazine, one or
more flat springs h h, which press the pile of plates against the opposite wall or top
These springs are placed according to the line of displacement of the drawer, so
as not to prevent the movement of it.-
i.
At the upper part of the box BC, are arranged one or more small pieces in the
form of inclined planes, which project only sufficiently to seize one frame b, and
are so placed as to permit of the frames coming along with the drawer from the
position II into the position I (by reason of the flexion of the springs), but so as to
hold the top frame by catching its edge when the drawer returns to the position.II.
The apparatus will then be in the position shewn in Fig: 1, that is to say the
top frame b, being held back by the stop j, falls, when the drawer is pushed right
back, and has come to the position II, and the fallen frame takes up, then
the position b, 8, and is held there by the force of one or more permanent
magnets m, let into the floor g at the bottom of the chamber I, and flush with the
inside surface, the frames which hold the sensitive plates being made of suitable
inetal. When-the-frame-has fallen-to-the bottom of the chamber I, it is held there
stationary by the magnet or magnets. _
The action of the magazine is as follows:-In the position of the parts shewn in
Fig: 1, the plate b, which has fallen to the bottom, and is found in the
position b is the one to be exposed, a different arrangement to that which has been
in use up to the present.-In the magazines hitherto in use, it was, in effect, the top
or front plate of the drawer which was exposed, when the drawer was in the
position I. Then, when this drawer was pushed back to the position II, the plate which
had been exposed fell to the bottom of the apparatus, lodging itself under the
pile of other plates, and becoming the bottom or back plate, when the drawer was

page_text: drawn back into the position I, for the purpose of presenting a 2nd plate for
exposure.
According to my system, I expose the plate bs, when fallen to the bottom of the
apparatus, and kept in position by the action of the magnets upon the metal frames
or plate carriers, the drawer being then in position II.-When this drawer is moved
into position I, the plate 6s, which has just been exposed, fits or enters under the
pile of other plates, is caught by small hooks fixed to the drawer, or by spring
stops n, such as are shewn in the drawing, then the drawer being pushed back into
position II the topmost frame is held by the hooks or stops and falling to the
bottom, takes the position 6 s, when the drawer comes to the end of its motion.-
When the magazine is drawn over the exposed plate, and is withdrawn with it,
the plate frame slides over the poles of the magnets. It is known that, under
these conditions, there is no appreciable resistance, and that the quality of the
magnet is not altered.-
It can be seen that a magazine on such a system diminishes the thickness of the
apparatus to merely that-of-the-pile of frames, which and permits of the reduction
in the length of the bellows, or in the size of the apparatus, if it contains a capacity
of fixed dimensions, in place of the bellows.―
As I have already said, I do not limit myself to any one particular arrangement of
the other parts of the apparatus, my invention only relating to the special arrangement
of the magazine.—
t-should-point out that the bulk of the apparatus-may-still-further-be-decreased
by making the magazine in such-a-manner-that-the-part-1-might-be-fitted-into-the
spee-II, while the apparatus is not in use.
With such an arrangement it is possible to reduce-the-size-of-the-apparatus-to
that-of-the-bulk of the pile of plates.
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 :-
In combination with photographic apparatus of the hand camera order a magazine
consisting of a drawer a furnished with metal plate carriers b, working in a dark
chamber fitted with permanent magnets m, and in a box c furnished with springs h,
stops k, and catches n, and operated by rods d, and a ring e, all substantially as
described.
A-drawer-magazine-for-photographic-apparatas, having the plate frames-made-of
suitable metal arranged-so-as to expose--not-the-front or top-plate, brought into
the focus of the objective, but that plate when it has fallen-to-the- bottom of the
apparatus, and--is kept in position by magnets acting on the-metal-frames the
magazine having been pushed-back from-its place in-that-part-where-the-image-is
taken, the focus consequently being on a level with the plate furthest-from-the
onjective, but on a level with the opposite-end-plate; ns-has-been-explained--and
described-with-regard to the-accompanying drawing.—
