PROVISIONAL SPECIFICATION.
An Improved Photographic Magazine Hand Camera.
WILLIAM BULLOCH, Twenty-eight Glenfield Street, Glasgow, Letterpress Printer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to Photographic magazine hand cameras, and has for its
objects mainly to dispense with the use of sheaths for plates or films and also to
dispense with any notching or cutting of films whilst providing protection against
access of light to the spare plates or films during the exposure of any single plate
or film.
The improved apparatus comprises a light-tight box or magazine into which the
plates or films are deposited. The plates or films are inserted from the back of the
magazine which is preferably hinged or otherwise fitted to open up for access to
the interior, the lid or back having a spring thereon for pressing the plates or films
forward into register as they become discharged from the magazine. The plates or
films are separated one from the other by a card, in size somewhat longer aud
narrower than the photographic plate or film. The interior of the box has a small
square pin or bar fitted into each of its four corners, these pins or bars having for
their object the keeping of the plates or films separate and distinct from the cards;
which are placed between in the following manner,--first a plate or film is placed
in the magazine having the pins or bars, bounding its shorter sides or shorter
dimensions of the said plate or film, then a card is placed in the magazine in a
similiar manner but with the pins or bars bounding its longer dimensions and so on,
one plate or film and one dividing card alternately, till the magazine is filled; when
the back of door bearing the pressure spring is closed.
The outer sides of the box or magazine are fitted with movable spring bars or
rods to which are connected flat bars or rods which lie along the front edge of the
magazine and project into its inner dimensions slightly less than the thickness of
the small pins or bars fitted into the inner corners of the magazine, thus forming a
rebate edge whereby the plates or films are retained within the magazine.
The top and bottom bars or rods are connected together by means of a connecting
rod or bar and projecting arms or cranks at the extremity of the bars or rods on
which the said rebate bars or rods are pivoted, being so connected that both open
or close simultaneously on a projecting end of the said pivoted bar being depressed.
The spring rebate bars or rods, on the sides of the magazine are independent of
each other, and are normally open, that is they do not project into the inner
dimensions of the magazine until such times as they are required to do so, which
will be hereinafter stated.
The magazine herein described is hinged or pivoted at its base and enclosed
within a light-tight box of suitable dimensions said box forming the camera proper,
in such a manner that it can be turned by means of a handle or lever on the outside
of the camera; from its normal vertical position in which position the exposure by
uncovering the lens is made; to a horizontal position, in which position the magazine
is ready to discharge the exposed plate or film to-gether with the intervening card
in the following manner.

page_text: When the magazine is turned down by means of the handle or lever on the outside
of the camera the side spring rebate bars or rods engage with small projecting
plates fitted to the inner sides of the camera, which press the side spring rebate
bars or rods inwards till they project over the edge of the dividing cards within the
magazine, after which the top pivoted spring bar or rod which retains the plate
or film, engages with a projecting arm or plate which depresses the extremity of
the pivoted bar or rod and simultaneously opens the top and bottom rebate bars,
and in so doing the exposed plate or film drops by its own gravity into the well at
the bottom of the camera provided for its reception.
By turning the magazine back to its former vertical position, a reverse action of
the aforementioned spring takes place, first the top and bottom spring rebate bars
or rods disengage from the projecting arms or plates and return to their place
projecting over the next plate or film to be exposed; then the side springs become
disengaged from the projecting plates on the sides of the camera and spring back
to their normal position when they no longer support the card which consequently
falls into the well on top of the exposed film, completing the turn necessary to bring
the magazine to its vertical position. completes the changing action.
The plates or films are retained in their place in the well or receptacle by means
of a pivoted spring door which is raised to a vertical position in the front of the
camera and when in this position closes the lens aperture after which the changing
of plate or film is effected, and the shutter or lens cap being set is turned down on
top of the plates or films in the well, thereby protecting them from any reflected or
other light and at the same time keeping them firmly within the well or other
receptacle should the camera be required to be turned for any purpose, as for taking
pictures in a vertical direction.
On one side of the camera is fitted an indicator disc or dial bearing on its face a
series of numbers one of which is visible at a time through an orifice. This indicator
is made to advance by one every time an exposure is made thus registering the
number of plates or films exposed.

COMPLETE SPECIFICATION.
An Improved Photographic Magazine Hand Camera.
WILLIAM BULLOCH 28 Glenfield Street City of Glasgow Letterpress Printer 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 Photographic Magazine Hand Cameras, and has for its
objects mainly to dispense with the use of sheaths for plates or films, also to
dispense with any notching or cutting of films as heretofore; and generally to
facilitate the operations of changing and recording the changes of plates or films.
The invention is illustrated in the accompanying drawings at Fig. 1 back view
of camera with the door of camera removed showing the magazine also with its door
removed.
At Fig. 2 Front view of magazine and at Fig. 3 in vertical section.
Referring to the illustrations Fig. 1. 2. 3. the improved apparatus comprizes a
light tight box or magazine A into which the plates or films are placed. The plates

page_text: or films are inserted from the back of the magazine Fig. 1 which is fitted with a
door B. Fig. 3 bearing a spring thereon for pressing the plates or films into
register as they become discharged from the magazine. The plates or films aro
separated one from the other by a card, in size slightly longer and narrower than the
photographic plate. The interior of the box or magazine has a small square pin
or plug C in size corresponding to the difference of the size of the dividing card
and the photographic plate or film tho said pins having for their object, the retaining
of the plates or films separate from the dividing cards, the plates or films being
deposited in the interior of the magazine fitting into its shorter dimensions so made.
shorter by the said pins; while the dividing cards fit the longer dimensions of the
magazine, one plate or film and one dividing card in alternato succession, being
placed into the magazine. On the top and bottom outer sides of the box or magazine
is fitted a bar or catch D bent at right angles one edge projecting over the inner
dimensions of the magazine, thus forming a rebate for the photographic plate or
film to rest on; it being pivoted at the rod E which is fixed to and forms a part of
the said bar or catch, a spring F fixed to the lever I pulls the rebate bars into
contact with the sides of the magazine, these rebate bars on the top and bottom of
the magazine are connected one to the other by the tie rod G so that when the
lever H which is connected to the pivoted rebato bar on the top, is depressed both
robate bars open simultaneously, and close by the action of the spring F when.
released. The magazine is provided with similar rebate bars D' on its shorter sides,
these bars are simple strips or bars of spring brass or steel tending to spring
outwards from the sides of the magazine as shown in Fig. 2, both rebate bars act
independently. When depressed inwards these bars project over the inner edge of
the magazine and form a rebate edge for the dividing cards within the magazine.
On the bottom of the magazine a rod I is fixed; by means of plates K. K. screwed
to its base, and on this rod the magazine is pivoted and enclosed in a box L of
suitable dimensions, said box forining the exterior case of the camera proper, in
such a manner that it can be turned by means of the handle or lever I which is
screwed or fixed to one end of the pivot rod I of the magazine, which is made to
project through the side of the camera.
The magazine is kept in a vertical position within the camera by means of a
small projecting pin me on the handle or lover engaging with a hole in the spring M
which is screwed on the outer side of the camera. In this position the plate or
film is exposed, by uncovering the lens, and when such exposure is made the
exposed film is disposed of and a fresh plate or film obtained in the following
manner :-
The handle or lever being disengaged from the spring M it is turned down to a
horizontal position and when in this position the side spring rebate bars D' are
pushed in by the plates O which are fixed to the inner sides of the camera, so that
they project over the inner sides of the magazine and retain the contents of the
magazine, while the exposed plate or film is released by the lever H of the top
spring rebate bar D being depressed by coming in contact with the projecting plate
or knob O', and opening the rebate bara, when the exposed plate or film thus
released from its support, drops by its own weight into the chamber or well N for
receiving the exposed plates. As the magazine is turned back to its normal vertical
position a reverse action of the spring rebate bars takes place,--first the lever H
disengages from the projection O¹ closing the rebate bars D then the side rebate
bars open simultaneously, by disengaging from the side plates O, when the dividing
card is released and falls into the well on top of the exposed film, the magazine being
returned till the catch spring engages with the pin on the handle or lever, it is
ready for another exposure, and so on until the magazine be empty.
Referring to Fig. 3 in order that the exposed plates shall be retained in the well N,
and at the same time be protected from all light other than that they have received
through the lens, a flap P bearing on its surface a spring P¹ and pivoted at the
rod p on the end of and within the camera is fixed a pulley p¹ over which a cord Q
passes, the cord being fixed to the pulley p¹ at one end, and to the top of the

page_text: magazine at the other, the cord is just such a length that when the magazine is in
the vertical position indicated at Fig. 3 the flap is pulled firmly down over the well
and immediately the magazine begins to be lowered to change a plate, the flap is
quickly raized to a perfectly vertical position by a helical or other spring T wound
round its axis p thus sealing the camera from all light through the lens during
change of plate, and removing the flap that the change can be effected.
On the top of the box is fitted a disc or indicator dial R bearing on its face a
series of numbers one of which at a time is visible through an orifice ¹, this
indicator is operated so as to advance by one the number exposed through the
orifice, each time the magazine is raized the projection S engages with a pin or
tooth on the disc and turns it the requisite extent at each exposure so as to indicate
the number of plates exposed.
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 improved magazine or changing box for photographic cameras, the parts
of which are constructed, combined and arranged to operate substantially as
described with reference to the annexed drawings.
2. In a magazine or changing box so constructed that its inner dimensions form
two distinct compartments each compartment holding a plate or film, or card suited
to its dimensions, and in conjunction therewith, of movable rebate bars so fitted to
the sides of the magazine, that by the alternate opening and closing of these rebate
bars a plate or film and a dividing card is released from the magazine in alternate
succession.
3. The principle of exposing plates or films without sheaths or notches by means
of dividing cards differing in size from the photographic plates or films, and arranged
alternately in a box or magazine having square pins fitted into its inner corners,
substantially as described.
