2. Means and appliances to enable the operator to carry lenses into the field
with him to suit different pictures so that buildings, landscapes and figure subjects
can be taken in the same camera also for determining the focussing position of the
lenses.
3. Meaus and appliances for regulating the period of motion of the time shutter
for exposure.
4. Means for shutting out of lens any objectionable foreground.
5. Means by which the plates can be shifted for focussing and removing the
plates.
6. Means for enclosing a light tight hood within its receptacle when not in use
and for recording the exposures made.
7. Fitting a shutter to the front board of the camera to preserve the lens and to
prevent views being obtained should the time shutter be accidentally released and
a plate spoiled.
To carry my invention into practice I make the casing in three parts, viz., an
adjustable lens portion, a fixed portion, and a removable changing box in which
the plates are arranged and I fit spring clips and lip plates at the connecting
edges for enabling the changing box to be readily attached or removed as desired.
The lens portion and the fixed portion have the expansible bellows affixed and the
lens portion is capable of being pushed away or drawn inwards by a rack and
pinion operatable from an outside turn button, the distance being determinable by
a gauge or vernier plate on the casing, said plate sliding under a fixed strip or
otherwise as a guide and as an indicator of the distance. The time shutter with a
slot in it is upon rollers and governable by a spring which can be wound up for
regulating its action for quickness or timing for exposure purposes, said spring
being released by a push pin from the front.
In connection with the spindle of one roller is a paul which when the time
shutter is not required such as for very long period exposures said paul can be
released by a push stud to permit the spring to run down and rewind the time
shutter upon its roller or out of action.
The changeable box is provided with a lifting lever, this having an end
projecting from the outside to lift each plate in succession into the light tight
bag to be shifted by hand when desired, the lever being returnable by a spring.
This changing box has a hinged lid to close upon and exclude light from entering
the bag should it be faulty said lid on the inner surface having a ruled tablet
for records of the exposures.
The camera box is provided with two enclosed sight lenses or finders with sight
boles at right angles to each other and the focussing lense with its holder is capable
of being raised to shut out objectionable foreground.

Improvements in or relating to Hand Cameras.
SAMUEL WHITE ROUCH 180, Strand London W.C. Manufacturer of Photo-
graphic Apparatus, 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 certain details in the construction of hand cameras fitted
with my plate changing appliances working in separate reservoirs or magazines
detachable from the camera, as patented 17th March 1888 No. 4145.
My improved hand camera may be described as follows-I provide it with two
or more lenses adapted to fit the same flange in the usual way one of them being of
short focus and capable of including a wide angle of view, the other having a
longer focus. This permits of any desired amount of the subject that is to be
photographed being included in the picture.
The camera, which when in its normal state for wide angle views is very small,
may be distended to any desired length so as to suit the lens or lenses of longer
focus; this being effected by means of a bellows or gusset body attached to the
front portion to which the lens is fixed and to the rear portion in which the
sensitive plate or film is carried. The extending of the camera for adjusting
the focus is effected by a suitable rack & pinion. A ground glass screen is not
necessary for sharp focussing, as this can be equally well done by means of suitable
scales graduated and engraved to suit the various distances at which either of
the lenses is in focus.
My improved hand camera has a swing back of any suitable construction, and
the front to which the lens is attached has a suitable sliding motion as to permit
of its being moved in either a vertical or horizontal direction.
The exposure of the plate is made by means of the band-shutter described in
Specification No. 6613-1887 placed behind the lens & having an orifice which
passes across the lens with any required degree of rapidity.
In the detachable magazine I provide an index of any suitable construction
which automatically registers the number of plates that have been exposed from
the magazine. This index is moved by the action of the lever which must be
pressed each time a plate is exposed. When by the indication of the register
the full number of plates contained in the magazine is found to have been
exposed the light tight shutter of the changing back is closed, the magazine is
detached, and another containing a fresh supply of plates can be inserted in its
place.
The rapidity of the exposing shutter is determined by a spring which when much
braced up gives the greatest degree of rapidity-but the tension may be removed
from the spring by releasing the paul of a ratchet as usually employed in such
shutters and in this state the shutter moves with a slow action caused by the
relaxation of the spring. By adjusting the bracing-up of the spring any inter-
mediate degree of rapidity is obtainable, and when once set the action is always
afterwards uniform.
Instead of confining the transference of the plate to from back to front as
described in the claims of my Patent No. 4145 A.D. 1888, I now give the option of
transferring it in the opposite way or from front to back.
In the accompanying drawings
Figure I shows the camera with the magazine attached, and arranged for lens of
short focus. In this A represents milled head of the pinion, B a focussing index,
and C the detachable magazine.
Figure II is a view of the camera when extended for use with lens of long focus,
showing detachable back removed and its place taken by an ordinary focussing
screen for use in making cap exposures, enabling ordinary dark slides or roll holder
to be employed if desired.

page_text: What I claim is the use in connection with the camera described in my
Specification No. 6613—1887.
First. The employment of more lenses than one, these being of wide and ordinary
angle.
Second. Adjusting the focus of lenses by rack and pinion attached to the body
of the camera.
Third. Placing the shutter behind the lens and adjusting the power of the
propelling spring in the manner described.
Fourth. The graduated scale for showing when the lens is focussed for any
particular distance of object.
Fifth. The application of a swing back.
Sixth. The automatic registration of the number of plates exposed.
Seventh. An arrangement for moving the lens front in either a vertical or
horizontal direction.
