PROVISIONAL SPECIFICATION.
Improvements in or connected with Magazine or Hand Photographic
Cameras.
1, EDWARD HOBART MICHAEL SEYMOUR of 10 Duke Street, Bloomsbury in
the County of Middlesex Bachelor of Arts do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in or connected with magazine or hand
photographic cameras whereby films may be employed without the ordinary
sheaths or backings so that an increased number thereof may he provided for,
without materially adding to the total weight and bulk of the camera.
According to my invention the entire camera is divided by a sliding partition, in
front of which are located one above the other, the camera proper or exposure
chamber and the magazine or storage chamber, and behind said sliding partition is
located the receiving chamber for the reception of the films after their exposure.
By the operation of the sliding partition the films (which are arranged vertically)
are conducted in succession from the magazine to the camera proper whence, after
having been exposed, they are shifted into the receiving chamber by means of
suitable contrivances that operate during the return movement of the sliding
partition, the said film remaining in their vertical position or nearly so during the
whole movement.
In carrying out the invention the sliding partition which is operated by hand or
by mechanical means may be provided with projections or abutments which when
the partition is shifted, or withdrawn, to its full extent protrude sufficiently to
engage with the edge of the film that is in proximity to said partition, so that when
said partition is shifted in the opposite direction, or pushed in, this film will be
carried through a narrow slit into the exposure chamber or camera proper ready
for exposure.
In contiguity to said narrow slit are arranged suitable devices such as spring
stops which will allow the film to enter but prevent it from being withdrawn again
with the slide.
The means employ for enabling the film to be shifted into the receiving
chamber may consist of a pair of flexible arms or blade springs which are situated
one at each side of the exposure chamber and they may be connected together at
their free ends so as to constitute a kind of flexible frame which bears upon the
greater portion of the margin of the film and serves the additional purpose of
keeping the film in register. These flexible arms or blade springs give way when
the partition, with its film, enters the exposure chamber and as said partition
is withdrawn push the film into the receiving chamber at the back of the
partition.
If desired the flexible arm may be supplemented by a pair of pivolted spring
controlled turn-pieces, or the like, one for each arm, which would add to the
efficiency of the action of the flexible arms.
It would be found advantageous to provide means such as spring stops or
the like for preventing the exposed films from becoming displaced from the
receiving chamber during the withdrawal of the sliding partition.
The sliding partition may also be furnished with stops or other suitable means
for limiting the extent of its withdrawal.

page_text: The before mentioned narrow slit through which the films pass into the exposure
chamber may be made capable of adjustment so as to suit films of varying
thicknesses.
Both the magazine or storage chamber and the receiving chamber are fitted with
spring controlled pressure-boards for acting upon the films and keeping them in
place one against the other and constantly pressed Lowards or against the sliding
partition.
By simple modifications 1 can if desired construct the camera so as to enable
films or plates with sheaths to be employed.

Improvements in or connected with Magazine or Hand Photographic
Cameras.
1, EDWARD HOBART MICHAEL SEYMOUR of 10 Duke Street, Bloomsbury in
the County of Middlesex, Bachelor of Arts, 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 improvements in or connected with magazine or hand
photographic cameras whereby films may be employed without the ordinary sheaths
or backings so that an increased number thereof may be provided for without.
materially adding to the total weight and bulk of the camera.
According to my invention the camera is provided with a sliding partition or
pusher in front of which are located one above the other the cainera proper or
exposure chamber and the magazine or storage chamber, and at the rear of said
sliding partition or pusiter is located the receiving chamber for the reception of the
films after their exposure. By the operation of the sliding partition or pusher
which is provided with a suitable projection or protruding fillet for engaging with
the edge of the films, said films (which are disposed vertically in the magazine) are
successively carried from the magazine to the exposure chamber. After having
been exposed in this chamber they are shifted into the receiving chamber, by
means of suitable contrivances, during the return movement of the sliding partition
or pusher, the films remaining in their vertical position during the whole time.
In order that my said invention may be clearly understood and readily carried
into effect I will describe the same more fully with reference to the accompanying
drawings, in which
Figure 1. is a central vertical section of the camera.
Figure 2. is another vertical section taken on the line 1. 1. of Figure 4 and
shewing the parts in another position.
Figure 3. is a longitudinal horizontal section taken on the line 2. 2. of
Figure 2.
Figure 4. is a transverse vertical section taken on the line 3. 3. of Figure 1.
Figures 5. 6. and 7. shew the sliding partition or pusher separately, Figure 5.
being a face view of that side which comes into contact with the films; Figure 6.
a vertical cross section on the line 4. 4. of Figure 5; and Figure 7. another
vertical cross section on the line 5. 5. of the same figure.
Figure 8. is a fragmentary longitudinal section taken on the line 6. 6. of
Figure 1.
Like letters of reference indicate similar parts in all the figures.

page_text: A is the exposure chamber and B is the magazine located immediately above it
and separated therefrom by the horizontal partition C; D is the sliding partition
or pusher at the rear of which is the receiving chamber E. F are the films
which are arranged vertically within the magazine B. and are kept normally
pressed towards the pusher by the pressure-board under the action of the
spiral spring '. In the drawings this spring is shewn as surrounding a tele-
scopic stem. This telescopic stem is composed of two tubes the inner one b
being capable of sliding freely within the outer one . These tubes are provided
with longitudinal slots * (see Figure 3) in which works a stud or pin carried by
the rod . The rear extremity of the slot in the outer tube is formed with a
transverse extension into which the said stud or pin can be caused to enter
when the rod 6 is drawn back sufficiently and turned in the proper direction. In
this manner the pressure-board can be conveniently retained in its retracted
position while fresh films are being inserted into the magazine.
The sliding partition or pusher D is provided with a transverse fillet d whose
lower edge protrudes slightly beyond the face of the pusher and constitutes a ledge
which when the pusher is in its fully elevated position (Figure 1) projects just
sufficiently to engage with the top edge of the film that lies immediately against
the face of the pusher. The back of said pusher is furnished with vertical
racks with which engage toothed wheels . These tothed wheels are
connected together by a hollow axis and are capable of being revolved by a
crank-handle or other suitable means situated on the exterior of the camera.
turning said crank-handle in one or other direction the pusher can be caused
to move up or down within the guide grooves formed in the sides of the
camera.
By
Situated within the exposure chamber A, one on each of the side walls thereof,
are triangularly-shaped turn-pieces aa which are free to be turned about their
pivots a. These turn-pieces have their corners rounded and are controlled by
blade springs a² which are so arranged that said turn-pieces normally occupy the
position indicated in Figure 1, that to say with one or other of their corners
projecting into the path of the pusher.
Near the upper part of the camera and located just behind the pusher, when this
latter occupies its elevated position (Figure 1), is a pressure board or box G
carried between guide strips g. g. This pressure-board is made of box form and
is provided with an internal spring g' which constantly tends to push said pressure-
board or box into the position indicated in Figure 2. The lower edge of the
face of this pressure-board or box is curved for the purpose hereinafter
stated.
H. is a removable tray having a pair of depending nebs h. h. which when said
tray is in position within the camera project over and in front of the upper portion
of the films as best seen at Figures 2. and 4. and serve to prevent the upper edges
of the films from advancing, under the action of the pressure-board b, too far
forward whilst the pusher is descending and thereby preventing them from coming in
the path of the top edge of the pusher when the latter ascends. The lower surface
of said tray also serves to prevent the films from shifting upwardly during the
ascent of the pusher as would otherwise occur owing to the adhesion existing
between the films due to the pressure with which they are pressed forward against
the surface of the pusher by the spring controlled pressure-board. The said tray
is supported horizontally by the side edges and is prevented from shifting out of
its proper position by means of fixed side blocks 69 which engage with corresponding
recesses in the tray.
The horizontal partition C. does not extend entirely up to the pusher whereby a
space or sliti is produced between said horizontal partition and the pusher through
which the films pass from the magazine into the exposure chamber when acted upon
by the pusher. In order to render the width of this space or slit adjustable,
so that films of varying thicknesses may be provided for. I employ a thin bar
covered with velvet or other suitable material. This thin bar is connected to a pair

page_text: of slides ♬ that are capable of moving in dovetailed grooves formed longitudinally
in the horizontal partition C. The opposite ends of these slides are connected
together by a transverse bar having a screwed boss at its middle through which
the screwed portion of the pin passes. This pin is mounted in a bushing
secured to the transverse vertical partition and is free to be turned in said
hushing but without shifting longitudinally. By slightly turning said pin in one or
other direction the velvet covered bar can be caused to approach towards or
recede from the face of the pusher and the size of the slit i can thus be adjusted to
suit the thickness of the particular films employed.
The edge of the horizontal partition C. is also furnished with a pair of resilient
stops which give way to the film as it descends through the before mentioned slit
under the action of the pusher, but resume their norinal position as soon as the
upper edge of the descending film has passed them. By these means the film
after having been fully inserted into the exposure chamber is prevented from being
again withdrawn through the said slit as the pusher returns to its elevated
position.
The face of the pusher where it rubs against the resilient stops is provided with
vertical metallic strips which at their upper ends terminate in knife edges d'.
These strips are countersunk into recesses provided for their reception in the
pusher so that they lie flush with the surface thereof, and the upper portions of
these recesses are made somewhat deeper as seen at of so as not to interfere with the
before mentioned nebs h, when the pusher ascends to its full extent.
K. is a lever pivoted at k. to one of the side walls of the exposure chamber and
having at its rear extremity a freely pivoted arm & formed with a ratchet tooth.
The front end of this lever is sufficiently long to project into a recess with
which the lower part of the pusher is provided (see Figures 5. and 7.) so that as
each film is brought down by the pusher said lever will be actuated thereby and the
ratchet-wheel of the indicating mechanism be thus operated. is a spring
finger which passes transversely over the upper end of the pivoted arm and
whilst permitting of said end moving freely prevents it from becoming displaced.
This arm is likewise so formed that it normally lies in the position shewn
at Figure 1 that is to say out of engagement with the teeth of the ratchet-wheel.
It will thus be seen that the indicating mechanism can only be operated by the
lever when the camera is tilted into a position to cause the pivoted arm to
approach the ratchet wheel so that when said arm is actuated the ratchet
tooth will come into engagement with the teeth of the ratchet-wheel. is a light
spiral spring which normally keeps the front end of the lever K. in its raised
position (Figure 1).
Lis a lid or cover with which the upper part of the camera is furnished and
Eerves to close the opening through which the films are inserted into the
magazine.
Assuming the parts to be in the position indicated at Figure 1; when the pusher
is caused to descend it carries the film which is in immediate contiguity to its face
down with it through the slit by reason of the lower edge of the fillet of engaging
with the upper edge of the film as already explained; the next adjacent film being
prevented from following owing to the said slit being too narrow to permit of more
than one film at a time passing therethrough. The pusher and its film continuing
to descend the lower edge of the pusher collides with the turn-pieces a thereby
cansing these latter to revolve on their pivots for about a third of a revolution and
to assume the position indicated in Figure 2. The turn-pieces now press against
the margins of the film and firmly retain it in its vertical position against the
pusher and keep it there until after the exposure has taken place. Meanwhile the
pressure-board G. acting under the influence of its spring approaches the films in
the magazine and by pressing against them prevents their upper portion from being
forced forward by the spring pressure-board 5. into the path of the pusher. It will
be seen that when a film lies against the face of the pusher it covers the recess
and consequently as the pusher descends the lower edge of said film acts upon the

page_text: lever and operates the indicating mechanism when the camera is tilted. In the
event however of a film not being carried down by the pusher the said recess *
remains uncovered and therefore the lever K. does not get actuated and the
indicating mechanism remains unaffected. In this way the operator can readily
ascertain whether the film has been carried into the exposure chamber, and at the
same time a false indication of the number of films exposed is avoided.
The film having been exposed, the pusher is elevated; the said exposed film
being prevented from rising with the pusher and again entering the magazine by the
resilient stops. As soon as the pusher rises high enough the turn pieces a are
caused to continue their revolution, and assume the position shewn at Figure 1,
under the action of their springs, at the same time forcibly ejecting the exposed
film into the receiving chamber E the said lever K then assuming its normal
position. The film can be taken from the chamber by opening the door or slide E'.
The pusher continuing to rise, its curved upper edge comes into contact with the
lower curved edge of the pressure-board G. thereby forcing the latter back into
its original position. When the pusher is fully elevated the nebs h. are housed in
the cavities and lie behind the top edges d' of the metal strips d³.
The parts are then ready to be actuated as before, the same cycle of operations
again taking place as already explained.
The front M. of the camera is made moveable in order to enable the rod to be
conveniently operated.
Although in my Provisional Specification I alluded to special means acting in
conjunction with the before mentioned turn-pieces for enabling the film to be shifted
into the receiving chamber I have since found that such means are unnecessary and
can be dispensed with.
If desired the receiving chamber E may be provided with a pressure-board
controlled by a light spring which will gradually become compressed as the films
are successively shifted into the said receiving chamber under the action of the
pivoted turn-pieces a.
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. In a magazine or hand camera for use with films without sheaths or backings
a sliding partition or pusher having a protruding fillet and working in conjunction
with spring controlled pivoted turn-picces and resilient stops for the purpose
specified.
2. The construction of the sliding partition or pusher for use in a magazine
or hand camera substantially as described and for the purposes specified.

resilient stops for preventing the film from being withdrawn from the exposure
chamber during the return movement of the pusher; means for adjusting the size
of the space or aperture through which the films enter the exposure chamber; and
