Improvements in or relating to Photographic Cameras.
A communication from the KOZY CAMERA COMPANY, of 44, Bedford Street, Boston,
Massachusetts, United States of America.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to improvements in that class of photographic cameras
which are designed to be carried about in the pocket, or otherwise, and to that end
require to be folded within a small compass.
In the drawings Fig. 1 is a perspective view, showing the camera opened.
Fig. 2 is also a perspective view, showing the camera closed, the door through
which the film-rolls are introduced, being opened. Fig. 3 is a side elevation of the
camera opened, the outer casing, or frame work, being indicated by dotted lines,
the interior mechanism being shown in full lines. Fig. 4 is a similar view of the
same parts with the camera closed, and containing an independent plate-holding
device. Fig. 5 is a plan view of the film-supporting platen and connections
removed. Fig. 6 is a rear end elevation of Fig. 5.
In carrying out this invention, the camera box, or casing, is made in two
parts 10, 12. By a hinged connection at the rear ends thereof said parts are held
together, and movement thereof is permitted for swinging the free ends of said
parts one from the other in order to open the camera box for use, as shown in
Figs. 1, 3. Between said parts a folding bellows, 14, of light-excluding material,
is arranged for excluding light in the usual manner. Said parts are supported in
open position by a bar, 16. Said bar has one end in pivotal connection with the
part, 12, and has its other end in sliding connection with a rod, 18, attached to the
part 10, this being in order to permit the movement required of said bar in folding
the camera parts together, as shown in Fig. 4.
In the outer, or free end of part 10, is located the lens and its shutter
connections. This arrangement is an important feature of this invention. By it
the obliquely arranged lens is brought into focal position, perpendicular to the
film-supporting platen, 20, by the simple operation of opening the camera, and it
allows of the platen being securely and economically connected with the part 12.
In carrying out the arrangement of platen, 20, within the chamber of part, 12,
my correspondent has had in mind to arrange for the introduction of an inde-
pendent plate-holding device, 24, Fig. 4. To this end the platen supporting con-
nections are made adjustable, whereby movement of the platen adjustably is
allowed from the focal plane, as shown in Fig. 3, to a plane there below, where
upon the independent plate-holding device, 24, of usual construction for holding
glass plates, may be introduced through a suitable opening at the back of the
camera part, 10, and rest upon the platen, 20, all as shown in Fig. 4.

The platen, 20, is formed of sheet metal with roller connections, supported at
the sides thereof in the usual manner. At the front and back ends of the platen
and integral therewith, are downwardly extending plate-projections, 40, 42,
formed by overturning and projecting downwardly the platen metal. Said plates
are made to bear in sliding connection one with the inner face the back wall of
part, 12, and the other against the face of supporting block, 28, and they are
held in place by screws, 30. Said screws being located in oblong slot 32, 34, have
only to be loosened in order to permit the platen being moved to different planes
of altitude below the focal plane.
Supported for movement rotatively in the rear end of part, 12, is the stud, 44,
on which to support one end of a film holding roll and it has winding connections
to engage the spool at that end. On the plate, 40, is a stud, 46, whereby to
support the other end of said winding spool. The spool from which the sensitized
material is taken is supported on the studs, 48, 50, the film being made to pass
over the platen, 20, is thereby supported in the focal plane. To permit the
described adjustment of the platen, 20, plate 42, has an oblong recess, 52, allowing
for the winding-stud 44. The plate 40, is cut away from the platen, 20, except at
the central part thereof, as shown in Fig. 2, in order that the end portions thereof
may be sprung outwardly as indicated by dotted lines, Fig. 5, and thus permit
introduction and removal of the film-holding spools. The normal tension of said
parts in springing back to place operates against the end faces of said spools and
gives a tension thereto for holding the film tightly drawn. For ordinary purposes
this tension is sufficient, but a spring is provided in support with the part, 28,
and bearing with its ends against the plate, 40, as shown in Fig. 5. The support-
ing block, 28, will be understood as having a fixed connection with the frame
part, 12. The lens and shutter devices are supported by a block 60, (Fig. 4),
whilst 76 (Fig. 1) indicates a shutter releasing push button and 68, is a shutter
setting device.
Having now particularly described and ascertained the nature of the said in-
vention, as communicated to me by my foreign correspondent, and in what manner
the same is to be performed, I declare that what I claim is :-
:-
1-The combination with an enclosing box formed of two halves or sections
hinged together at their rear ends to open and shut, and a light excluding bellows
connecting the sides and front ends of the two box sections, means located within
one box section for supporting a sensitized surface, and a lens mounted within the
free front end of the other section and adapted when the box sections are swung
apart to be brought into proper focal relation to the said supporting mean 3,
substantially as described.
2-The combination of a two part camera box having a hinged connection at
one end permitting free movement of the parts to open the same, a light exclud-
ing bellows between the parts for excluding light therefrom when opened,
mechanism including the platen, 20, and roll supporting connections, for holding
the sensitized film located in the chamber of one of said parts, and a lens for
throwing the image upon the sensitized film, said lens being located obliquely in
the free end of said other part, whereby when the lens carrying box section is
swung out the proper distance from the platen carrying section, the lens will lie
in proper focal relation to the platen, substantially as described.
3-The combination of a two part camera box having a hinged connection at
one end permitting free movements of the parts to open the same, a light exclud-
ing bellows between the parts for excluding light therefrom when opened, mech-
anism including the platen, 20, and roll supporting connections for holding the
sensitized film, located in the chamber of one of said parts, the adjustable con-
nections permitting displacement of the platen, 20, to make way for an independent
plate-holding device, and lens for throwing the image upon the sensitized material,
said lens being located in the free end of said other part, substantially as de-
scribed.

page_text: 4 The combination with the enclosing box formed in two sections hinged
together at their rear ends, to open and shut, and connected therebeyond by a
light excluding bellows, of a lens mounted in the front end of one box section,
a platen or hold for the sensitized surface mounted within the other box section,
and a bar pivoted to the inner side of one box section and in sliding connection with
the other box section to brace the box sections apart when the lens reaches its
proper focal relation to the said sensitized surface, substantially as described.
5 The combination with the enclosing box formed of two sections hinged
together at their rear ends to open and shut and a bellows connecting the sides
and front end of the box sections, of a lens mounted in the front end of one box
section, and a platen mounted within the other section and having parallel end
flanges provided with roll-carrying pins or studs, one of said flanges being cut
away to form springs and permit the pins or studs carried thereby to be sprung
into and out of engagement with the film rolls, substantially as described.
G-In a camera the combination with the platen 20 having parallel end
flanges 40, 42, provided with the roll-carrying pins or studs, the flange 40 being
cut away to form springs for the pins or studs 48 of an auxiliary spring 54 covering
at its end on the flange springs, substantially as described.
Dated this 26th day of July 1898.
