Improvements in or pertaining to Photographic Cameras.
We RICHARD WHITEHORSE SAVAGE of 22 Bagby Road Leeds in the County
of York Architect and Surveyor and THE SUS CAMERA COMPANY LIMITED of
22 Bagby Road aforesaid Manufacturers and Dealers do hereby declare the nature
of this invention to be as follows:-
The object of our invention is to improve the construction and fitment of photo-
graphic cameras in various details to render the same more efficient and generally
convenient.
We erect two standards of a semicircular or curved section wherein the front of
the camera can slide and which front is constructed with a central circular opening
into the front whereof the lens tube can be screwed while on the internal edge
thereof is a flange which may extend as far therearound as desired. A frame is
secured to the front end of the bellows which has a corresponding central circular
opening and certain parts are removed from the edge of this opening corresponding
with the aforesaid flange which parts being brought together the frame is pressed
home and partly turned to cause the edge of the aperture to pass behind the flange
and thus secure the two parts together after the manner of an intercepted screw
proper stops being fitted and the two parts being light tight. To this sliding front
is fitted an horizontal pinion shaft actuated by a screw head which gears into racks
on the standards to raise or lower the front. Stave can be fitted to the standards
and through the upper parts thereof clamping screws are fitted to the standards the
heads whereof pass through slotted plates on the sides of the sliding front to
retain the same at the desired elevation. The standards can be erected on a
movable platform fitted in the base on the edge whereof is a rack into which a
stationary pinion engages to move this platform transversely and the platform
can be made in two parts one part being centrally pivoted on the other part
and thus while the lower part only moves transversely as aforesaid the upper
part that carries the standards not only moves transversely therewith but can
also turn on its pivot and be clamped in any position by any usual devices.
At the rear end of the base of the camera is mounted a platform which may be
capable of sliding therealong and through this platform rises the head of a screw
bolt preferably on both sides of the base fitted with such nuts and other appliances
as to be capable of being clamped on and to the web or webs of or to the base.
The upper surface of the platform is concave transversely to the base to form a
seat for the complementary convex edge of the back which convex edge is formed
on the bottom and on one of the sides thereof to allow the back to be mounted on
the platform in two positions and plates are secured on these edges wherein are the
usun slots formed across the same into which slots the heads of the screw bolts can
pass and travel behind the same. By this arrangement the platform can be placed
in the desired position the back can be engaged thereon and be erected or inclined
or laid flat as the slots may allow and then the appliances on the screw bolts will
clamp all these parts together. The platform may also be fixed on the base by one
preferably the front edge in which case the rear edge is capable of being raised or
lowered and there clamped and then the back will not need to be inclined and the
convex edges are not required but the back on its two sides as aforesaid can be slid
into a groove in the platform.
On this back is the usual focussing screen contained in an hinged frame and this
screen is provided with and can be covered by folding doors preferably fitted so
that when the doors are opened the screen is moved towards the lens and rice tersa
and round and between these doors are fitted flexible webs which when the doors

page_text: are opened entirely enclose the screen except where an aperture is left through
which the focussing can be performed without the usual cloth and inside the focussing
screen a recess may be made in the frame wherein a negative can be placed for
enlargement or reduction or otherwise.
The ordinary dark slides may be used in this back or a detachable magazine for
a continuous film can be constructed and applied thereto as follows. A closed
cylinder is made to contain a roll of sensitive film and along this cylinder is secured
a semi-cylinder which can tightly fit on the opened top of the back inside of which
semi-cylinder is a closed cylinder and a narrow passage is made through this
cylinder into the aforesaid cylinder wherethrough the end of the film can pass to a
roll in the latter cylinder all parts of course being light tight. To the axis of this
roll is secured a handle which may surround the outer side of the back and when
this magazine is placed in position this handle can draw the lower cylinder down-
wards to the bottom of the back exposing so much of the film in readiness for the
exposure to light after which the handle can be lifted and a spring inside this
cylinder so lifted rolls the exposed film up therein suitable pawls or stops being
fitted to both cylinders to govern the rolls and then by again drawing down the
lower cylinder a fresh surface of the film is exposed and so on.
The base of this camera may be formed as usual and to extend the same a
transverse rod with right and left handed screw threads may be mounted on the
stationary part on which threads are winged sleeves whereto are jointed prefer-
ably on both sides a series of reticulated bars duly jointed together the end
pairs of bars being jointed to the sliding parts of the base or these reticulated
bars may be fitted on one side only or when there are two 01' more sliding
parts to be extended on one side racks can be fitted on all the parts and the
pinions on the transverse rod would first extend the smallest part and then the
next and so on and when this base is long the back of a smaller camera
be connected with the front of the bellows of a larger camera by clips or
screws the intermediate back being supported from the base by travelling
standards.
can
This camera can be enclosed in a bag or box in the bottom and lower part
whereof are such apertures as may be required for working the same or con-
necting it to its stand by its base to which this bag or box can be attached.
The bag or box is divided transversely into two parts which can be opened to
expose the camera and closed and fastened to cover the same and are so fitted as to
hold also the dark slides roll holder spare lenses shutters and other appliances.
A long board has a longitudinal slot wherein can travel the screw bolt by which
this board can be connected to a tripod or stand and two or more platforms can
travel along this board being fitted with racks and pinions clamping screws and
other appliances. On one platform a smaller camera can be secured and on the other
a larger camera the front whereof can be attached to the hood of the lens of the
smaller camera by metal strips or otherwise whereby an enlargement or a reduction
may be produced and this long board will also serve for exhibiting photographs by
placing a lantern behind the camera on the one platform which can be supported by
any stand if desired while the other platform carries the exhibiting surface.
On
This camera can be contamed in a rectangular rigid easing which is divided
transversely into two parts the front part containing the lens shutter and other
parts with a finder if desired and the rear part Eding inside the front part.
the sides of the front part are pivoted two levers the upper arms whereof carry or are
commected with a magazine of sheathed sensitive plates while the lower arms thereof
are connected with the sliding back. Springs and other appliances are fitted in the
magazine to force the plates forwards, and when a plate comes to the front it drops
a little way down below the magazine and engages on each side at its lower part
studs on the sliding part of the casing. The exposure is given while the plate is in
this position and then the sliding back is drawn out foreing this exposed plate down
on its face as its lower edge is being drawn back by this sliding back and the
magazine is being moved forwards by the levers and by such action compressing

page_text: springs under its sides until when the back is drawn out as far as allowed this plate
is clear of the magazine and is by the springs caused to regain its vertical position
when the back can be pushed in again thus causing the magazine also to regain its
normal position with a fresh plate in the front and the exposed plate in the rear
and so on.
A suitable door can be made preferably in the sliding back where-
through the exposed plates can be removed and fresh ones inserted and any suitable
indicating appliances may shew what number of plates have been exposed. The
pulling out or the pushing in of the sliding back can also obviously be utilized in
setting the shutter by the appropriate means as also for focussing by a distance
scale of the sliding back and otherwise.

Improvements in or pertaining to Photographic Cameras.
We RICHARD WHITEHORNE SAVAGE of 22 Bagby Road Leeds in the County
of York Architect and Surveyor and THE SUN CAMERA COMPANY LIMITED of
22 Bagby Road aforesaid Manufacturers and Dealers 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 object of this our invention is to improve the construction and fitment and
arrangement of photographic cameras in many and various details to render the
same more efficient and generally useful and convenient.
In order the more clearly to explain this our invention and in what manner the
same is to be performed we refer to the accompanying drawings wherein we have
shewn a photographic camera and various parts thereof and adjuncts thereto as
fitted with and according to our said invention as will hereinafter be fully detailed
an described.
On Sheet Figure 1 is an elevation of the front of a camera,
and Figure 2 is an horizontal section thereof taken at a b.
with rigid standards
Figure 3 is an elevation of the front of a camera with standards that can be
inclined and Figure 4 is an horizontal section thereof taken at ed.
Figure 5 is an elevation of the frame at the front end of the bellows of a
camera.
The standards A of the front may be of the ordinary section shewn in Figure 2
but and especially when they are to be capable of inclination by being pivoted at
their lower ends in or on the bare B of the camera as shown in Figure 3 we
preferably make them of a semicircular or curved section as shewn in Figure 4 and
in and between these standards A the front of the camera can slide upwards and
downwards. This front C is constructed and fitted in the usual manner with a
central circular opening ("into the front whereof the lens tube can be screwed
while on the internal edge thereof is an elbowed flange (which may be continuous
and extend all round the same when certain portions of the elbowed part thereof
would be cut away and removed or may be in separate pieces as is shewn in
Figure 4 which would be secured at the desired intervals therearound. A frame D
is secured to the front end of the bellows E of the camera wherein is a corresponding
central circular opening D and certain portions of the edge of this opening Di
corresponding with or complementary of the aforesaid elhowed parts of the
flange Care cut away and removed as shewn at D'all which parts are so arranged
and formed and proportioned and are so brought together that when the retained
portions of the elbowed part of the flange Center the removed portions D² of the
edge of the opening D' the frame D can be pressed home and then partly turned to
cause these retained portions of the elbowed part of the flange (to pass behind
the edge of the opening D'and it may be into a rebate D³ formed therefor and thus
these two parts of the camera namely the bellows and the front are safely secured

page_text: together after the manner of and through the style of action of an intercepted screw
all the parts of course being made light tight in any usual and convenient manner.
We preferably so arrange and form these parts that the bellows can be so secured
to the front in two positions and any suitable stops or catches D' may be fitted to
retain the same in the desired relative positions as may be requisite.
When the standards A are rigid the sliding front can be raised or lowered by
an horizontal pinion shaft (which may be mounted on the front in any desired
position and would gear into racks A fitted on the standards A in the proper
corresponding positions or rice versa the racks may be on the front and the pinions on
the standards. When the standards A are capable of inclination or when they are
made as aforesaid of a semicircular or curved section or on other occasions when
desired slotted plates can be secured on the sides of the front ( through which
slots can pass and behind which plates and along which slots can travel the heads
of screw bolts A the tails whereof pass through the standards A it may be through
longitudinal slots in the same and also if so fitted through slots in the stays A³
formed and arranged and pivoted on the base B in any usual or other manner and
serew nuts on these bolts A can clamp all parts together with the rising front at
the desired elevation and if so fitted with the standards either vertical or at the
desired inclination.
On Sheet 2 Figure 6 is a side elevation of a folding camera when extended
Figure 7 shews the same when closed and Figure 8 is a plan of the base of the same.
Figure 9 is a side elevation of a non-folding camera and Figure 10 is an elevation
of the back of the same.
At the rear end of the base B of the camera is mounted a platform F which in
Figures 6. 7 and 8 is capable of sliding therealong and can be retained in any
position by clamping screws which pass through wings F projecting down-
wardly from the platform over the sides of the base into slots B₁ formed
therefor in these sides of the base B. The upper surface of the platform F may
form a seat for the edge of the back H of the camera and therefore may be shaped
and made in any convenient manner whether concave or fat or otherwise or in
other suitable manner this platform may support the back two adjoining edges of
the back being complementarily formed so that the back can be mounted on or
supported by the platform in two positions as is shewn in Figure 10 where the back
is delineated in these two positions one being shewn by dotted lines.
In Figures 6.7 and 8 we shew one method of fitting this platform to support the
back in various positions whether vertical or inclined wherein a rearwardly pro-
jecting platform G is hinged to the travelling platform F and thereon or thereto are
fitted bolts (which can enter into slotted recesses formed therefor on two
adjoining edges of the back H and therein can be clamped by screw nuts or other-
wise to secure the back to the hinged platform ( in one of the aforesaid two
positions. On or in the wings of the platform are formed curved slots F³
wherethrough pass elamping screws (fitted on wings G³ projecting forwardly
from the platform G and thus it is obvious that the back I can be secured in
whatever position may be required whether vertical or inclined or folded flat down
as the lengths of the slots Fa may allow.
In Figures 9 and 10 we shew a platform that is not capable of sliding along the
base and according to this method of fitting the same the wings of the platform F
are pivoted on the sides of the base Bas shown at Fat or near their front edges
and clamping screws B fitted on the sides of the base B pass through curved
slots formed in the wings F near the rear edges thereof and thus in this case
al-o it is obvious that the back I can he secured in whatever position may be
required whether vertical or inclined or otherwise as the lengths of the slois F may
allow. We also shew another method of securing the back on the platform wherein
a recessed groove is transversely made on or in the platform complementary
grooves being similarly made near two adjoining edges of the back whereby
the back being slid into the recessed groove is secured on the platform.
In Figure 9 we also shew the front end of the bellows of a larger camera con-

page_text: nected with the back of a smaller camera when the focussing screen thereof has
been turned over out of the way and this back is most conveniently carried on and
by a
travelling or fixed support preferably so fitted as shewn to be adjustable
and capable of being raised and lowerel and it may be of being folded down out of
the way.
On Sheet 1 Figure 11 is an elevation of the back of a camera and Figure 12 is
an horizontal section thereof.
On the back is the usual focussing screen H³ contained in the ordinary hinged
frame and on this frame or as is perhaps preferable on or in another frame K which
can be connected to and supported by the frame of the focussing screen H' or
elsewhere by pins or otherwise in any usual or convenient manner are hinged
folding doors which can cover the focussing screen H³ when closed and may be
so arranged and fitted in any ordinary manner that when these doors are opened
the focussing screen is moved somewhat towards the lens and rice versa and round
and between these doors K are fitted flexible opaque webs K² which when the
doors K' are opened as is shewn in these figures entirely surround and enclose the
focussing screen H³ except where a suitable central opening is made or left through
which the focussing can be performed without the aid of the usual cloth and an
hinged stay K may be fitted to retain these doors K' in the open position so long
as may be desired.
The ordinary or other dark slides may be used in and with the back as may be
desired as also may any suitable roll holder.
In Figure 13 we shew the transverse section of a detachable magazine or roll
holder for a continuous film that can be used with the back and Figure 14 is a
vertical section of the back with this roll holder in position.
A closed chamber L is made of a somewhat cylindrical section and of the proper
dimensions to hold the film and fit on the top of the back and this chamber Lis
divided longitudinally into two part- 1ª and Lª the meeting edges of these parts
being so constructed and fitted it may be as is shewn in these figures that when
they are placed together they are quite light tight whereby the sensitive film
within is preserved from damage. In the several parts L' and L of this chamber L
are severally mounted longitudinal rolls Land and round the upper roll 1. is
wound the sensitive film L the outer end whereof is attached to the lower roll L'.
The upper part or edge of the back H is closed by an hinged flap it may be
normally retained in the closed position by a suitable spring and the chamber L
properly charged can be placed on and in the opened top of the back I forcing
down the flap 11' and then all parts are in the positions shewn in Figure 14 and
are of course so fitted in any usual and convenient manner as to be light tight. To
the axis of the lower roll or it may be to the ends of the lower part 1 of the
chamber are fitted handles or as is perhaps preferable the ends of one handle M
which surrounds the outer side of the back I passing out from both ends of the
axis of the lower roll L'or of the lower part through vertical slots M' made in
any suitable positions in the bark and when this magazine is placed in position
as shewn in Figure 14 this handle M can draw the lower part of the chamber
with its contained roll down and away from the upper part L.' of the chamber
and its contained roll L. thereby obviously drawing so much of the sensitive film L
off this upper roll L3 and preparing it for and placing it in position in readiness for
the intended exposure to light and it is very convenient so to fit the several parts
that when the lower part L2 of the chamber has reached the bottom of the back H
it will be turned on its side as is shewn by dotted lines in Figure 14 and this may
be effected by studs fitted on the inner sides of the back and on the ends of the
lower part
of the chamber in the proper corresponding positions to come in contact
with each other or by causing the handle to perform this turning through tappets
on the said sides or els or otherwise in any usual and suitable manner as may be
desired and when all parts are in position as aforesaid this lower part of the
chamber can if necessary be retained by stops or catches or otherwise. According

page_text: to this arrangement the so exposed portion of the sensitive film L' will be pushed
back close to the focussing screen 113 as is shewn by dotted lines in Figure 14 in
proper register with the lens. When the desired exposure has been completed the
stops or catches if any can be retired and the lower part 1 of the chamber can be
lifted up by the handle M promptly regaining its normal upright position and a
suitable spring which is applied in any ordinary manner to the lower roll L
immediately causes this lower roll 1 to revolve and roll up on itself that portion
of the sensitive film L³ that has been so exposed as aforesaid and this aforesaid
lifting is continued until the lower part 1 of the chamber has regained its normal
position in conjunction with the upper part L' thereof and all parts of this apparatus
are in readiness to repeat this aforesaid cycle of operations and then by again
drawing down the lower part of the chamber a fresh portion of the sensitive film
will be drawn off the upper roll in readiness for the intended exposure to light and
so on until all the sensitive film has been so exposed when the magazine can be
removed from the back. Any ordinary and suitable pawls or stops or brakes or
other usual appliances are fitted to both the rolls in any convenient manner to
allow and govern their necessary movements hereinbefore described and to disallow
and prevent any reverse or other movements.
On Sheet 3 Figure 15 is a perspective view of the back of a camera Figure 16
is a section thereof taken at eand Figure 17 is a section thereof taken at gh.
A rebate is formed either on the inner side of the focussing screen frame H
as shewn in Figure 16 or in the face of the inner part of the back II as shewn
by dotted lines in Figures 16 and 17 or in both wherein a negative can be placed
to be enlarged or reduced as may be desired and pins II' can be fitted to hold the
same in its required position and it is sometimes convenient that the inner part II°
of the back I should be separately made and then be connected to or placed in
position in the outer part of the back. Another rebate His made in the outer
part of the back II as shewn in these figures wherein a corresponding projection
formed on the edge of a dark slide 11° can be inserted as shown by dotted lines in
Figure 17 the opposite edge of the dark slide H being held by the hinged clips 10
mounted therefor on the edge of the back and retained in position by the
pins H7.
Figure 18 is the plan of the base of a
construction.
camera according to one style of
The base B may be constructed in any usual extensible manner and according to
this style the same has two or more sliding parts which extend in opposite
directions at the same time. A transverse rod X whereon right and left handed
screw threads are formed on the opposite ends thereof is mounted on the stationary
part of the base B on which threads are mounted winged sleeves N whereto are
jointed on both sides the first pairs of two series of reticulated bars N2 duly jointed
together in the ordinary manner the end pairs N³ of both series of bars being
jointed to the outer ends of the sliding parts 1 of the base B3 and thus by turning
the rod N in the proper direction it is obvious that the sliding parts of the base
are either extended or drawn in. In the same manner two or more sliding parts
may similarly be extended on both sides the end pairs of both series of reticulated
bars being jointed to those sliding parts that extend the furthest.
These reticulated bars may also similarly be fitted on one side only of the
transverse actuating rod so that the base can be similarly extended also only on
one side.
Figure 19 is the plan of the base of a camera according to another style of
construction.
In this case also the base B may be constructed in any usual extensible manner
and according to this style the same has two or more sliding parts which extend in
the one direction only. A transverse rod P' whereon pinions are formed is mounted
on the stationary part of the base B which pinions gear into racks on these
sliding parts and suitable spring stops P₁ are secured on the underside of

page_text: the outer one B of the two sliding parts on the free ends whereof the inner
one B of the two sliding parts bears and thus when the rod P is turned in the
right direction only this inner one B of the two sliding parts is first extended
and when this has attained its full extension and is stopped by the check
plates P it has released the spring stops which therefore fly up releasing
the outer one B' of the two sliding parts which in its turn by the continued
turning of the rod P is caused to be similarly extended and when so extended
suitable spring stops are similarly fitted in the proper positions to retain both
the sliding parts when so extendeil as shown by dotted Enes mitil these stops are
retired. In the same manner more than two sliding-parts may similarly be
extended in the one direction only in their due required sequence as hereinbefore
described.
On Sheet 4 Figure 20 shews a bag case or box which can contain the camera
and Figures 21. 22 and 23 shew details of the fasteners thereof.
The bag case box or receptacle R for the camera may be made of wood or
leather or any other suitable rigid or flexible material and the base R' thereof
is so made and of such a form and dimensions that this receptacle R can be
placed and can remain on the top of the tripod S or other supporting appliance at
all times and whether the receptacle R be closed or open and such apertures are
made in the base R' that the receptacle R or the camera within the same can be
secured to the tripod S or other supporting appliance in the usual or other desired
manner. The receptacle R is divided transversely into two parts R' and R³
which are hinged or jointed or otherwise attached to and on opposite extremities
of the base R and can when required be dropped down into the positions shewn
by dotted lines in Figure 20 whereby the camera that is mounted on and it may
be attached to the base R' in any convenient manner is entirely exposed. When
these two parts R2 and R are lifted up to enclose the camera the upper edges
thereof that meet each other can pass under a central and preferably a rigid handle
band R and may if desired be connected thereto by any usual or suitable catches
while on the lower edges thereof and correspondingly on the handle band R may
be fitted the fasteners shewn in detail in Figures 21. 22 and 23. On the lower
corner of the meeting edge of each of the two parts R2 and R³ and it may
preferably be on each side of the receptacle R is fitted a circular plate T and on
the outer face of this plate T in a certain desired position in that upper quadrant
of the face that is furthest from the meeting edge is made or fitted an elbowed
claw T. On and in the lower part of the handle band R' is transversely mounted
a pin T on the outer end whereof is a disc T or it may be as shewn in Figure 21
only a part or a segment of a disc and on the inner face of this disc T are made
or litted two similarly but complementarily elbowed claws T in such positions as
may be needed to enable these claws T to engage the aforesaid claws on the
two parts R2 and R³ of the receptacle and large radial slots T are made in the
plates T whereinto the pin T can enter as and when these two parts R2 and Rare
lifted up to enclose the camera. When therefore these parts R' and R' of the
receptacle have been so lifted up the disc T3 can be so turned that the two claws T'
thereon engage the two claws T on the plates T whereby both
parts R² and Rare
securely held and retained in the closed position or the disc T may be so turned
as to release one or both of these parts by disengaging one or both of the claws T4
thereon from one or both of the claws T on the plates T as and when may be
desired. This receptacle herein before described may be so fitted in any convenient
manner as also to contain dark slides roll holders spare lenses and other appliances
and if and when it may be desired to use this receptacle with its contained camera
as an hand or portable camera a suitable aperture would be made in the side of the
receptacle for the lens and if necessary or convenient a view finder and other
suitable appliances would be provided and fitted to or in the receptacle.
This camera and the several methods of and appliances for attaching and con-
necting the same and its several adjuncts and appurtenances together as hereinbefore
described can obviously be used for many and various purposes and objects and in

page_text: many and various ways the attachments and methods of application and arrange-
ment and fitment hereinbefore described being adjusted and used as may be
necessary or convenient for the particular purpose or object in view.
As an example on Sheet 3 Figure 24 we shew a method of using this our
invention for enlarging or reducing purposes and Figure 25 shews the details of
the same partly in section.
When the hood of the lens tube V has been removed a frame V2 made and
fitted exactly similar to the front of a camera as hereinbefore described premising
of course that the central circular opening therein is made of the proper diameter
is passed over the lens tube and then the hood is replaced so that the
frame cannot be drawn off the same. The front part of the bellows of the
other camera provided with the frame D hereinbefore described can then be
safely secured to the frame V in manner as herein before described in respect of
these parts.
And so in like manner we could use many of the hereinbefore described methods
of and appliances for attaching and connecting and retaining in place the different
parts of the camera and its several adjuncts and appurtenances for purposes and
objects differing from those that are hereinbefore described and set forth.
Again as an example we would mention the rebate the clips and the
pins 17 hereinbefore described in respect of holding a dark slide in and with the
back H which could be similarly used for holding the front end of the bellows of
a larger camera and for holding the front part of an optical lantern as well as
many other parts for different purposes and objects.
On Sheet 4 Figure 26 is a vertical section of an hand or portable camera.
The camera is contained in or is formed by a rectangular rigid casing W the
rear whereof is open and into this rear slides another similar but smaller casing WA
the front whereof is open and this casing W properly and rather tightly fits into
the casing W in which casing Ware contained and fitted in any usual or con-
venient manner the lens shutter and other required parts and appliances such as a
view finder and the like. On the two sides of the front part W of the casing at
the proper height thereon are centred two rocking levers X the upper arms
whereof carry or are connected to a magazine X made in any usual or suitable
manner wherein are a number of sensitive plates duly and properly backed or
sheathed in a vertical position facing the lens in the lens tube V while the lower
arms of the levers X are connected with the sliding back part W of the casing.
Springs or other usual and suitable appliances are fitted in the magazine X to
force the plates forwards and when a plate thus comes to the front it drops a little
way down below the magazine X and projections or jaws at each side on its
lower part or as is perhaps preferable on the lower part of its sheath engage
studs on the bottom of the sliding back part W' of the casing or it may be on
a carrier X formed therefor. The required exposure is given while the plate is
in this position and then the sliding back part W of the casing is drawn out
forcing this so exposed plate downwards on its face as is shewn by dotted lines
at as its lower edge is being drawn backwards by this sliding back part W
while the magazine is being moved forward by the levers X into the position
also shown by dotted lines and by this action the plate 7 compresses springs Z
under its sides which are properly mmmred therefor on the bottom of the sliding
back part W until when this sliding back part W of the casing has been drawn
far as is allevel as also is shown by dotted lines this plate Z is so clear
of the magazine N¹ that the springs cause it to regain its vertical position as
also is shewn by dotted lines but obviously in an inverted and reversed position
whereby its sheathed back is presented in the direction of the lens and then the
sliding back part W₁ can be pushed in again thus causing the magazine X1 to
regain its normal position with a fresh plate in front and the plate that has been
exposed in the rear and all parts of this apparatus are again in position in readiness
to repeat the aforesaid cycle of operations and so on until all the plates have been
exposed. According to this arrangement as hereinbefore described it is obvious

page_text: that those plates that have been exposed can never be subjected to a second
exposure for not only is the sheathed back now presented to the lens as is afore-
said but also the projections or jaws thereon are now at the top edges instead of
at the lower edges and therefore cannot again engage the studs on the bottom of
the sliding back part of the casing or on the carrier.
If and when the sliding back part W is long enough the magazine X' may be
stationary and need not be supported and therefore moved by the rocking levers X
which could therefore be dispensed with but the rest of the action hereinbefore
described obviously would be performed in a similar manner.
An aperture W would obviously be made in the front part W of the casing to
allow the admission of light to the lens and the back W of the sliding back
part W of the casing would preferably be hinged to allow the removal of the
magazine X and when desired the replacement of the same although other parts
of the casing may be fitted in any convenient manner for the same purpose and a
suitable handle W can be provided for convenience of carrying.
When instead of plates a continuous sensitive film is used in this camera the
sliding back part of the casing would be so connected with one of the rolls on
which this film is or is to be wound as to roll up thereon so much of the sensitive
film as had been exposed by the pulling out of this sliding back part and such
springs and pawls or stops or brakes or other usual appliances would be fitted to
both the rolls as also such connections between this sliding back part of the
casing and one or both of the rolls in any convenient manner as to cause and
allow and govern theso aforesaid necessary movements and to disallow and prevent
any reverse or other movements.
This pulling out or pushing in of the sliding back part of the casing may
obviously be utilized in and for setting the shutter by any appropriate means and
