COMPLETE SPECIFICATION.
Improvements in Photographic Cameras.
I, DAVID HENDERSON HOUSTON, Photographic Expert, of Hunter, County of
Cass, North Dakota, U.S.A., 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:-
Having invented certain new and useful improvements in photographie
cameras, I do hereby declare the following to be a full, clear, and exact descrip-
tion of the invention, such as will enable others skilled in the art to which it
appertains to make and use the same: my invention relates to photographic
cameras; and has for its object the provision of a camera adapted to use cut
sensitized films, or thin flexible plutes, such as celluloid plates sensitized for
photographic purposes, said films, or thin plates having an opaque backing
impenetrable to the rays of light coming through the lense of the camera, and
thus adapted to receive an impression in the sensitized surface of the plates, and
the opaque backing on the plates adapted to confine the action of light to the
surface of the first plate in the plate magazine of camera.
My invention consists in novel features of construction, and combination of
parts, which are hereafter fully described, and the novel features pointed out
in the claims at the end of this specification.
In the drawings, Figure 1 is a longitudinal sectional view of the complete
camera. Figure 2 a side elevation view of camera.
In the drawings in which similar letters of reference denote corresponding
parts in all figures; A, in Figure 2 represents a side view of the camera, and
showing the outside working handles and their stops, and also the slide that
closes the outlet of the plate box of the camera. In Figure 2 a friction roller
shaft B is shown having a handle N, held by a point thereon entered into a
grove T, in the plate S, and the said friction roller shaft B, in Figure 2 is a
continuation through the side of the camera case, of the same shaft B, as shown
in Figure 1. In Figure 2 there is also a shaft I, shown having a handle I,,
held by a point thereon entered into a grove P, in the plate R, and the said
shaft I
passes through the side of the camera case and is attached to the axis
of the plate box cover D, in alignment with the hinge K. In Figure 2 may
be seen the sliding cover Y, of the outlet of the plate box C, said sliding cover
having a thumb notch X. In Figure 2 may be seen the stop V, for the handle N.
In Figure 1, may be seen the pack of plates 1, and the first plate of the pack
released at its top side from the plate rest Z, and in the magazine box there is
placed a movable back O, having lugs G, G, said lugs supporting springs J,
said springs contained also within holes in the back of the camera case at J,
and held in by the plates L'
In Figure is shown a light-tight sliding cover F, covering the plate magazine
in a light-tight manner. In Figure 1 is shown a pack of plates E, said pack of
plates resting at their top against the plate rest 7, and resting at their bottom
against the friction roller B, said friction roller composed of a center shaft

page_text: of hard material covered over with a rubber surface, preferably a rubber pipe
forced over the hard center shaft. In Figure 1, is shown a swinging cover D,
of the plate box C, said swinging cover having its axis on the hinge K, and
closable over the plate box C. In preparing the camera for use, the operator
having placed a pack of sensitized, films having opaque backs, into the magazine
of the camera, and through the aperture that may be caused by removing the
cover E, and having placed the pack of films with the sensitized sides all
forward, and the whole pack before the movable back 0, the springs pressing
on the movable back will cause the pack of films to rest at their top sides against
the plate rest Z, and at their bottom sides on the bottom of the interior of the
magazine part of the camera, and also against the friction roller B, and having
replaced the cover F, and turned down the handle L, to the notch U, the camera
is prepared ready to be used, and which is accomplished in the following manner.
First, make the exposure by the shutter in the usual way; second turn up
the handle L, to the notch P, in the plate R; third turn up the handle N, from
the notch T, to the stop V, which will draw down the first plate in the magazine,
and thereby free the top of the first plate from the plate rest %; fourth, holding
the camera bottom down and front end 45 degrees lower than the back end,
then give the handle N a quick movement back to the notch T, which will
throw the exposed plate, or film into the plate box C; fifth, lower the handle L
to the notch U, which will inclose the plate into the plate box C, and the camera
is again ready for use.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declaro that what
I consider novel and desire to claim is:-
1. Combined in a camera, a case, the movable back in the magazine, said
movable back adjusted on springs, the cover of the magazine, a friction roller
adjusted to rest against the lower part of the side of the first plate in the
magazine, the interior of the case having a pit below the said first plate, whereby
the said friction roller can pull down the said first plate of the magazine to a
position below that of the other plates in the magazine.
2. Combined in a camera a case, a friction roller placed to bear against the
side of the first plate in the camera magazine, said friction roller having a core
of hard material, and said core of hard material inserted into a piece of rubber
pipe, and of the camera case having a recess adapted to allow the first plate to
pass from the position of the other plates in the magazine.
3. Combined in a camera, a case, a magazine having a closable aperture
adapted to allow access to the said magazine, the movable back in the magazine,
said movable back adjusted to spring a friction roller adjusted to rest against
one side of the first plate in the magazine, ɛaid friction roller having its axis
passing through one side of the camera case, a handle on the said axis, the
camera case having an interior recess adapted to allow the first plate in the
magazino to move from its position sufficiently to allow the opposite side of the
said first plate to be free from the plate-rest, the camera case having a closable
aperture connecting with the plate-box, said plate-box located in the interior
of the camera, the adjustable swinging cover of the said plate-box, said adjust-
able swinging cover having its axis at its front edge, said axis of said swinging
cover passing through the side of the camera case, a handle on the said axis
of the said swinging cover, and of a lense and shutter fitted to the camera.
4 Combined in a camera, a case, a magazine having a closable aperture adapted
to allow access to the said magazine, a movable back in the magazine, said
movable back adjusted to spring, a friction roller adjusted to rest against one
side of the first plate in the magazine, said friction roller having its axis passing
through one side of the camera case, a handle on the said axis, the camera case
having an interior recess adapted to allow the first plate in the magazine to
move from its position sufficiently to allow the opposite side of the said first

page_text: plate to be free from the plate-rest, and of the camera case having a closable
aperture adapted to allow access to the exposed plates.
5. Combined in a camera, a friction roller bearing against one side of the
foremost sensitized plate, said friction roller adjusted so that the said rollor
when rotated one way will draw the first plate in the magazine from the plate-
rest, and when said roller is reversely rotated the first plate in the camera
magazine will be thrown from the plate magazine into the interior of the camera.
6. Combined in a camera, plate-box in the interior bottom side of the camera,
a swinging cover on the said plate-box, said swinging cover having its axis
at the front side of the cover, said axis passing through the camera case, and a
handle on the said axis on the outer side of the camera case.
7. Combined in a camera, a case, a magazine having a closable aperture
adapted to allow access to the said magazine, a movable back in the magazine,
said movable back adjusted to spring, a friction roller adjusted to rest against
one side of the first plate in the magazine, means for oscillating the said friction
roller, the camera caso having an interior recess adapted to allow the first plate
in the magazine to move from its position sufficiently to allow the opposite
side of the first plate to be free from the plate-rest, and of a camera case having
a closable aperture adapted to allow access to the exposed plates.
