PROVISIONAL SPECIFICATION.
A Photographic Camera.
I, ALBERT PETER RILEY of 2 Upper Fenton Street Commercial Road East in the
County of London, Photographic Material Dealer, do hereby declare the nature of
this invention to be as follows:-
This camera is especially intended for use when travelling but is also of general
application and for indoor work. An important feature of my invention is that I
employ only one moving part which is actuated by the one hand only of the operator,
so as to move the dry plate into position or focus of the lense and so as to uncap and
cap the latter for exposure of the dry plate. In the camera or box 1 provide an
endless band of leather sheet metal or other suitable material such band passing over
a roller at each end that is to say at the back and towards the front of the camera.
Means may be provided for keeping the band sufficiently taut or for keeping it from
slipping. On this band. I fix at equal distances apart any suitable number (say a
dozen) of holders or clips. Each clip or holder is adapted to take a metal sheath
which contains a dry plate. The same lever, handle push rod, knob or pull serves to
actuate both the endless band and to cap and uncap the lense.
A suitable arrangement of this mechanism is as follows. On one of the endless
band rollers is fixed a pawl wheel or pin wheel which for every down movement of
the push rod lever or knob by suitable lever connection to said rod turns the wheel
to such an extent as to bring a dry plate into position directly opposite the lense
while the dry plate which has been exposed during the previous operation is turned
downwards out of focus of the lense. A helical or other spring serves to bring the
pawl back. The push rod has a spring catch or tappet tooth which on the depression
of the rod yields against the contact with a lever or part which carries the disc
forming the cap of the lense, but when the push rod is let go, and rises by the action
of a spring the spring catch or tappet tooth takes hold of the cap disc lever and
depresses the cap disc so as to expose the lense. The camera box may be fitted with
a view finder.
The box is conveniently carried in a bag like receptacle closed at the top where it
is provided with a handle and open at the bottom to allow the camera to be inserted.
The top of the bag is by preference made to represent a Gladstone bag and the push
rod or knob passing up through it may be made to fold down when out of use. The
side of the bag has an aperture corresponding to the lense aperture. The bottom may
be closed by a flap or flaps with straps or other suitable means of closure.
By means of the above apparatus instantaneous and time exposures may be effected
conveniently by the use of one hand only rapidly in succession and while the
apparatus is carried under the arm in the bag and without drawing undue attention
to the operations.

I, ALBERT PETER RILEY of 249 Commercial Road, but formerly of 2 Upper Fenton
Street, Commercial Road East, in the County of London, Photographic Material
Dealer 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 camera is especially intended for use when travelling but is also of general
application and for indoor work.
In the camera or box I provide an endless band of leather, sheet metal or other
suitable material such band passing over a roller at each end that is to say at the back
and towards the front of the camera. Means may be provided for keeping the band
sufficiently taut or for keeping it from slipping. On this band I fix at equal distances
apart any suitable number (say a dozen) of holders or clips. Each clip is adapted to
take a metal sheath which contains a dry plate or the like.
Or the holder and the sheath may be made in one piece. A lever or handle serves
to actuate the endless band and means are provided for bringing into position and
holding and for releasing the plates one by one.
Means are also provided in connection with one of the band rollers for registering
or indicating at a glance from the outside the number of plates that have been put
into focus and been used.
The accompanying drawings show a suitable arrangement of mechanism Figure 1
being a vertical central longitudinal section, Figure 2 a transverse section at the rear
end of the camera, Figure 3 a vertical longitudinal section near the inner right hand
wall, and Figure 4 a plan view with top of box removed. Figure 5 is a perspective
view of part of the endless band with some holders on it. Figure 6 is an end view of
one form of registering mechanism, and Figure 7 a sectional transverse view of a cap
or shutter mechanism. Figure 8 shews a sheath fixed directly on the band.
A is an endless band made of leather, woven fabric, woven wire cloth, sheet metal
or other suitable material. This band passes round rollers B and B arranged
respectively towards the front and rear of the box C the front roller B working
in fixed bearings D, D the left hand bearing D being supported by a frame on a
standard D2 on the left hand within the box, while the rear roller B¹ works in
adjustable bearings E E or blocks which are adapted to slide in slots or guides F F
fixed to the inside rear wall of the box, adjusting screws G G passing through the
outer end of the blocks E and capable of being turned from without by means of a
screw driver or by hand if made with milled heads; by this means the endless band
can be kept sufficiently taut and be kept from slipping.
On the band A are fixed at equal distances a number of holders H capable of taking
a metal sheath H' or the holder and sheath may be in one piece as shewn in Figure 8.
Each sheath receives a "dry plate." On the right hand end of the roller B within
the box C is fixed a pawl wheel or pin wheel I having four pins 1', and on the outer
end of the roller spindle is fixed a handle K, which when it receives a quarter turn in
the direction of the arrow in Figure 1 turns the wheel 1 to such an extent as to bring
a dry plate into position directly opposite the lens at L, while the dry plate which
has been exposed during the previous operation is turned downwards out of the focus
of the lens. The plate standing upright and while exposed to the lens is held up
against the end of the lever M which turns on a fulcrum M' and is held down by a
spring M². To this lever is fixed a rod M³ (or it may be made in one with it) which
at its lower end is jointed to a lever N having its fulcrum at N¹. As the handle K is
turned one quarter turn one of the pins I first comes in contact with the lever N,
thereby raising the rod M³ and lever M free of the upstanding sheath and dry plate;
thereupon the following ratchet wheel tooth I² raises the pawl rod O, the upper end
of which pushes up the lever P against the action of the spring P¹, thereby allowing

page_text: the next sheath and dry plate to come into register ready to be exposed and the one
that has been exposed to turn down.
This action may he continued untill all the dry plates have been exposed. They
are then taken out into the dark room and for this purpose the left hand side C¹ of
the box C is made detachable, being normally held in place by the cover or the side (1
may be hinged on. Q is a lever taking into another lever Q¹ which bears up against
a cranked part or projection on the rod O for raising its bottom end or pawl tooth
out of gear with the ratchet wheel I and thereby also raising the spring lever P clear
of the sheaths H' so that the band carrying them can be turned back into position for
refilling with dry plates.
R is a piece of cord or gut which at one end is attached to the last clip H in the
series and at the other end attached to a quadrant sector disc S which is provided
with numerals corresponding to the number of sheaths H¹, these numbers will one by
one show through a hole S₁ on the back side of the box, thus registering or indicating
the number of plates that have been used. S' is a spring for bringing the sector S
back.
In Figure 6 which shews a modified arrangement of register R is a pinion fixed on
the spindle of the roller B and gearing into a toothrack S which is provided with
numerals the same as the sector S in the previous example, such numbers also shewing
through a hole S' one by one.
TT is a bell crank lever one arm T³ of which is outside the box. This lever
by means of the rod T¹ carries the shutter T which is turned into the two positions by
the lever T3 with a quick and effective action. This construction involves only one
hole through the box viz. the one for the spindle of the bell crank lever.
The camera box may be fitted with a view finder.
In the Provisional Specification I described a connection between the shutter
mechanism and the endless band, and also a bag for enclosing the camera, but I have
not found these parts of my invention so practical as I anticipated.
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 photographic camera an endless band passing over a roller towards the
front and over a roller at the rear and provided with frames for holding plates or the
like and with means for moving the band so that the plates are one by one as required
moved into and held in position or register ready for exposure and released and
moved down out of register and with means for returning the band into the original
position for refilling with plates, substantially as set forth.
2. In combination with one of the endless band rollers the means for registering
the number of plates exposed, substantially as set forth.
3. The shutter T in combination with the rod T¹ and bell crank lever T2 T3.
4. The construction of camera shewn on the drawing.
