PROVISIONAL SPECIFICATION.
An Improved Magazine for Photographic Dry Plates or Negatives.
I, JOHN BOULTBEE BROOKS, of Criterion Works, Great Charles Street
Birmingham in the County of Warwick Manufacturer do hereby declare the nature
of this invention to be as follows:-
I will first describe my invention as applied to a magazine for use in a dark
room, for the purpose of holding dry plates or undeveloped negatives, and delivering
the same one at a time when required.
To this end I construct a box which opens at the top and bottom. The top of
the box is closed by a suitable cover or lid, which has its edges rebated to fit into
the top of the box, & which if hinged may be kept closed by a spring. The bottom
of the box is hinged at the back, thus forming a door which partially opens down-
wards. This door is kept closed by a lever spring affixed in a convenient position
at the back of the box, & is opened in the manner hereinafter described. The
interior of the box is made of the requisite size to take the plates easily but not
too loosely, the plates being put in from the top of the magazine, and lying flat one
upon another.
Across the front
I construct the apparatus for delivering the plates as follows.
of the box, inside, and near the bottom, I place a spindle on which are fixed two
circular discs through which the spindle passes concentrically. In each of these
discs make a notch which has one side directed radially to the circumference of
the disc, & the other side tangentially thereto. These discs & their spindle have
about half their substance recessed into the thickness of the front of the box.
spindle passes out through one side of the box, and is furnished with a handle or
key wherewith to turn it, & also has a lever fixed to it, & lying close to the side
of the box, and pointing in the same direction as the notches on the discs.
The
This lever is for the purpose of opening the bottom door of the magazine, upon
which I provide a suitable projection or plate for the lever to come into contact
with.
On the side of the box, near to and above the spindle I place a stud which
limits the extent of backward rotation of the lever and spindle.
Across the back of the box, I place another spindle which carries upwardly
projecting arms with a rebate cut in their upper extremities.
These arms are partly recessed into the back of the box, the recess being large
enough to permit of the arms being pushed backwards as hereafter mentioned.
The arms are pressed forward by suitable springs but have a stop to prevent more

than the lower edge of the rebate from projecting into the box.
provided with means for hanging on a wall or other suitable place in the dark
room; and so as to necessitate only a slight opening of the bottom door in
delivering a plate, the hanger is so made that the box is tilted forwards.
The action of the parts is then as follows. Any number of plates may be placed
within the box till full, & on the lid being closed the box is light tight. The plates
lie one upon another, the lowest having its front edge supported upon the two discs
fixed on the front spindle, and its rear edge upon the rebates of the arms on the
back spindle. To deliver a plate, the handle should be first turned till the lever
which is to open the bottom door of the box, points upwards, & comes into contact
with its stop; the notches in the discs are in the same direction as the lever,
consequently are upwardly directed, & the front edge of the lowest plate drops

page_text: into them. The handle is now rotated in the contrary direction, carrying round
the discs & the notches, and with them the front edge of the plate; the supporting
arms at the back edge of the plate yielding to allow of this action.
The rotation of the handle continuing, the notches turn till the front edge of
the plate drops out of them, and the plate slips bodily forward, and falls flat on the
bottom door of the box. The same motion of the handle also carries round the
lever, which coming into contact with the projection or plate on the bottom door,
presses it downwards; & the door being thus opened, and sloping, the plate slides
out into the hand held to receive it. On the handle being released, the door is at
once closed by its spring.
I adapt the same action to a magazine camera, in which case I place each plate
in an opaque sheath with the front cut away to admit of exposure; or a sheet of
opaque material may be placed between each plate. The plates are arranged
upright in the magazine of the camera and are pressed forward against the discs
by a spring, the spindle with discs being at the lower edge of the front plate, and
the spindle with yielding arms, at its upper edge.
After a plate has been exposed, it is delivered from the magazine by rotating
the spindle & discs, when it falls by the help of suitable guides into a receptacle
provided in the camera.
A door is opened by a lever and closed by a spring in a similar way to that in
the dark room magazine; but in the camera, this door is not placed on the magazine,
where it would interfere with the exposure, but is placed on the receptacle into
which the exposed plates fall.
As a modification of the magazine for dark-room purposes, I make the magazine
box upright, with a fixed sloping bottom.
Across the back of the box, inside, and near the bottom I place a small ledge,
which has a rounded or sloping edge to prevent the plates binding on it; and
immediately. above the ledge I make a recess sufficiently wide to admit the edge
of one plate only at a time. If desired this recess may have a spring to assist in
expelling the plate therefrom. Across the front of the box, inside, and directly
opposite to the ledge at the back, I place another ledge. Immediately above this
ledge, I pierce the front of the box, and insert one or more push-buttons, studs,
or plates, sufficiently long to push a plate off the front ledge, when pressed in
level with the front of the box. These push-buttons are attached to and operated
upon by the door hereinafter mentioned. The exit for the plates is a slit cut in
the front of the box, level with the bottom. I close this orifice. and also operate
the push buttons by a flap or door, which I hinge to the front of the box
above the push-buttons, which I attach to it.
.
This door is kept closed by a lever spring attached to the front of the box, & is
opened by a knob or handle affixed to it. The bottom & sides of the box are
extended & rebated to make a light-tight joint with the door. The action of this
form is as follows,-Supposing the door or flap of the box to be closed, & the
magazine then filled with plates, the lowest plate is supported at the back by the
rear ledge, & at front rests upon the push buttons. To deliver the first plate, open
the door or flap, which, withdrawing the push buttons, allows the front of the
plate to fall on the ledge. Upon closing the flap, the push buttons are pressed
inwards and push the back edge of the plate into the recess, but at the same time
the front edge is pushed from its ledge and falls; and the plate slips (and if a
spring is provided in the rear recess, is thrust) forwards and falls upon the sloping
bottom of the box; and upon the flap being raised, slips out into the hand held
to receive it and the handle being released, the flap is closed again by its spring.
After the first plate, only one opening and closing is needed for each plate, as each
time the door closes it causes a plate to drop on the bottom of the box ready to
slip out next time the door is opened.

I, JOHN BOULTBEE BROOKS, of Criterion Works Great Charles Street,
Birmingham, in the County of Warwick, Manufacturer, 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 appertains in one part, to photographic magazines, for the
storing and selective delivery of dry plates or undeveloped negatives, and is
particularly applicable for use in dark rooms; and in another part, to the
magazines of magazine cameras.
According to one form of the first part of my improvements, the magazine
consists essentially of a rectangular shaped box, provided with a hinged bottom
and a removable or hinged top, and with the interior fitted with mechanism or
means for delivering plates or undeveloped negatives one at a time. The hollow
interior of the box constitutes the store, wherein the plates are disposed pile-wise
with the lower plate resting upon ledges, which are drawn inwards or removed
from under the plate, which is dropped upon the hinged bottom, when the same
has been opened and inclined.
In another form of the first part of my invention, the magazine consists of a
rectangular shaped box with a removable lid or cover, and a hinged and opening
bottom, and with the interior constituting the magazine fitted with selective
mechanism and ledges and with the former operated by a pusher.
In the second part of my invention, the magazine, with plate selective mechanism
is combined with an ordinary photographic camera.
Figure 1 of the accompanying drawings represents in vertical section, a plate
or undeveloped photographic negative magazine, (for use in a dark room)
constructed and arranged according to one form of my invention. The said view
represents a pile of plates resting upon ledges located at the bottom of the
magazine, and with the lower plate of the series abutting against upright .studs
carried by the back and movable ledges, which are normally kept pressed
forwards by a spring.
Figure 2 represents a horizontal section of the said magazine, showing the
dispositions of the ledges and the means for withdrawing the plates one at a time
from the pile and delivering them down the incline of the open bottom.
Figure 3 represents a part of the said sectional view Figure 1, with the
selective mechanism in the position which it assumes on the first laying hold of
the first plate, prior to the said plate being moved backwards, so as to make its
front edge come clear of the shoulder of the selective mechanism.
Figure 4 represents the lower part of a like sectional view as Figure 1, but
with the lower plate being released, and the bottom of the body opened, by the
action of a wiper arın acting in unison with the releasing of the plate.
Figure 5 shows a back portion of the horizontal section Figure 2, with the
rear-plate-rests pushed back, by the plate which is to be released and delivered.
Figure 6 represents an elevation of one of the back rests.
The same letters of reference indicate corresponding parts in Figures 1 to 5 of
the drawings.
a is the body part of the magazine, of the figure of a rectangular shaped box.
having a removable bottom a', hinged at, a', and adapted to be closed when free
by a coiled spring b, whose lower end is attachedly connected to the said bottom,
inward of its hinge, and at its other end to the magazine body.
Located at the bottom of the back part of the magazine are pivoted part-shelf-
rests c, each having upright lugs or stops c', which form abutments for the back

page_text: edge of the lower plate of a pile to come against, and also stops for limiting the
inward movement of the said part-shelf rests, on the same being pushed inwards
by a spring d, or by springs. The inward stopping of the pivoted rests c, is made
by the lugs c' of them, coming at the back of and against the framing e.
The inside and bottom fore part of the body of the magazine is crossed by a
spindle, carrying at its middle part a disc or snail cam g, having a shoulder gl, and
with the end parts,, of the said spindle working within bearings and being
supported by the inner framing e, and with a turn 3, made fast to the said end f
and which said turn carries a wiper arm, which normally comes within the
interior of the magazine, and is adapted to open the fore part a³, of the hinged
bottom a', when the turn is rotated, for the taking of the lower plate from
the pile.
Assuming that a number of plates have been placed within the magazine, and
disposed pile-wise as in Figure 1, and with the back edge of the lower plate resting
directly upon the part-shelf-rests c, and the front edge resting upon the top of the
disc
first incline the magazine then rotate the spindle through the turn f³, from
left to right, when the plate will fall upon the part g³, at the foot of the shoulder g',
as represented in Figure 3. Now re-rotate the turn, from right to left, when the
shoulder g¹, is made to move forward and give a longitudinal traverse to the lower
plate, of the pile , and at the same time the part-shelf-rests c will be pushed
back, the spring d, compressed, and the hinged bottom a¹ will be opened through
the medium of the wiper arm f, which moves with the turn on the same being
rotated for the turning forward of the shoulder of the disc.
Now immediately the forward end of the plate becomes clear of the shoulder g'
of the disc, then the same falls, and is shot or impelled forward by the force of the
spring bringing the rests c, back to their normal positions. The plate now slides
down the open and inclined bottom and is thus delivered.
By now releasing the turn, the parts are taken back to their normal positions by
the closing of the bottom through the medium of the spring 6, and the same
operation is repeated for the obtaining of a second plate, and so on until the
magazine has been exhausted. When the magazine is not in use then the bottom a¹
is made fast to the body a by a catch i, whilst the hinged lid or cover j, is secured
or made fast to the said body a by the catch j'.
Figure 7 represents a modified form of plate or photographic negative magazine
for use in a dark room, consisting of a boxed shaped body a, with a fixed and
inclined bottom a', having a side opening a², and with the top enclosed by a lid j,
hinged or secured in any desired way. is a pile of plates or undeveloped
negatives, with the lower one h', resting at its front and back ends upon fast shelf-
rests c, and 9, and coming and working immediately above the latter is a pusher of
operated and controlled by a turn or hinged lever ³, (closed by a spring )
to which the said pusher g', is jointed at 11. This lever or arm forms also a closure
to the plate exit a', whilst fitted or located within the framing of the body, liguable
with the top of the rest c, is an expelling spring d, with head d'.
Now assuming that a number of plates have been placed in the box, and the same
require to be delivered therefrom one at a time and with the lower one h', being
supported by the shelf-rest or rests c, and upon the pusher g', then pull outwardly,
in the direction of the arrow, the door like arm, lever or shutter f, when
immediately on the pusher inner end becoming clear of the lower plate of the pile,
then the said pile falls and rests upon the ledge g. Now slide inwards the pusher g',
through the arın 93, when the lower plate ', will be slid backwardly and in its
traverse compress the spring d, and on the forward end of the plate coming clear of
the shelf rests e, then the said plate falls and rests upon the inclined bottom a¹ of
the box, which is then subsequently delivered on the next opening of the lever
shutter.
Figure 8 represents a longitudinal vertical section of a plate or undeveloped
photographic negative magazine, constructed and arranged according to a further
form of my invention.

page_text: Figure 9 represents a horizontal section of Figure 8 with parts of the selective
mechanism in elevation.
The lid j, may be jointed by side links, instead of hinges as before.
Figure 10 represents a transverse vertical section of Figure 9 looking towards the
back.
The same letters of reference indicate corresponding parts in Figures 8, 9
and 10 of the drawings.
a is the body of the magazine, with a hinged bottom a', (closed by springs b) an I
a removable or hinged top j, the hinged bottom a¹ has fitted to it an outside thumb
lever f, for the opening of same. The thumb lever has also attached to it
a quadrant slotted arm, which works over a pin or stud f, carried by a bracket
secured to the outside of the body.
This quadrant slotted arm guides and limits the opening of the hinged bottom.
9 are fixed front ledges and g¹ a movable pusher, sliding within a bracket g, and
having at its front end a blade y³, and with a coiled spring g', encircling a part of
the pusher, and adapted to return the same to its former position after the plate has
been removed from the ledges g.
c is a stationary ledge at the inside back of the magazine, and e' is a roller, pulled
down by a spring c³, and adapted to come upon the back edge of each bottom plate,
on the same being pushed rearward by the pusher.
The back end of the hinged bottom, inward of the hinge, has a stalk d, having
threaded upon it a pusher d¹, working between the ledge c and roller cl, and guided
by rests d³, so that as the bottom is opened, the pusher d¹ is brought forward, and
the forward end pushes the plate from off the ledge.
Assuming that a pile of plates are supported by the ledge rests g and C, and that
the same require to be delivered selectively or one at a time, then force in the
pusher 9', when the lower plate h', of the pile h, is slid backwardly, with the front
edge of the said plate clear of the ledges g, and the rear end forcing upwards the
roller, and being there retained between the said roller and ledge by the force of
the spring.
By now depressing the thumb leverf the hinged bottom is depressed and turned
upon its joint, and the stalk d made to describe a forward and radial movement,
which forces forward the pusher d¹, which in its turn releases the plate which
falls on the inclined bottom and is then slid out and delivered through the open
front.
By now releasing the thumb lever the hinged bottom again closes by aid of the
spring or springs b, and the parts resume their normal positions.
Plates are thus delivered one by one until the pile has been exhausted by
repeating the same operation as before.
Figure 11 represents a combined exposed plate magazine and camera, a is the
said magazine, fitted to a camera k, with an exposure compartment k', in which the
sensitized plates are placed, and with the top and bottom edges of the forward
one h¹, resting against the shoulder c, of the spring c, and the disc g, made fast on
a spindle f, and with an outside turn f³, for turning the said disc, to admit of the
transference of an exposed plate to the exposed plate magazine a. The said
spindle f, works within suitable bearings and has made fast to it, a wiper arm ƒ¼,
which operates the arm m', of a rocking lever in, pivoted at m³, and with the other
end m³, supporting a hinged closure a', whose fore part a', is presented to an
inclined plane a, coming opposite to side guides a. a is the lens of the camera,
a" the magazine proper for storing the unexposed plates, and a¹³ is a presser panel
coming at the back of the plates which stand edgewise, and brought up by the
spring a", located between the said presser panel and a fixed end of the
camera box.
Assuming that a plate h', has been exposed, and is required to be transferred to
the exposed plate magazine a, then slightly rotate in the direction of the arrow, the
turn f, until the shoulder g', of the disc g, has come under the lower edge of the
plate to be transferred. This done then re-rotate the turn, and bring the lower

page_text: edge of the plate forward, which is done by the yielding of the abutment spring c³,
and on the lower end of the plate being transferred clear of the disc, then the same
slides down the inclined plane a', and through the opening a, into the exposed
plate magazine a, by the opening of the light-tight door a', by the lever m, rocked
by the arm f, on the turn f³, being partially rotated.
To transfer cach successive exposed plate the same operation is repeated as before
whilst the unexposed plates are kept erect by the following-up panel a", through
the spring a".
Although I have described my invention for the storing of dry plates or
undeveloped negatives yet my invention is applicable to the storing of photographic
plates generally.
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 :-
First. A magazine or store for photographic plates, providing the same with
selective or one-by-one delivery mechanism, having a rest and delivery disc or
Snail cam, in combination with a push back or pivoted rest or rests, substantially as
and for the purpose as set forth in Figures 1 to 5.
Secondly. A magazine or store for photographic plates the selective means for
releasing, delivery and opening the spring bottom substantially as described and set
forth in Figures 1 to 5.
Thirdly. A magazine or store for photographic plates, the means of opening the
hinged or spring bottom, in combination with the rest and releasing means g, g', .c, c²,
as described and set forth in Figures 1 to 5.
Fourthly. A magazine or store for photographic plates, combining with the body
of the same, fixed rest ledges, with a pusher and spring abutment for releasing the
plates, and which pusher may be operated by a jointed arm, lever or equivalent, as
set forth in Figures 7, 8, 9 and 10.
Fifthly. A magazine or store for photographic plates, the combination with the
magazine of fore and aft movable pushers, and releasers, one independently
operated, and the other controlled and moved by the hinged or jointed bottom as
and for the purpose as described and set forth.
