Abstract
Abstract A camera comprising the combination of a box camera which is open on one side, and a self-contained film cartridge which is detachably secured to the camera to close its open side and thereby form a light tight enclosure. The camera has a photographic lens to expose the film in said cartridge, and a spring-urged apertured diaphragm shutter which is rotatably mounted between the lens and the cartridge. The camera is of simple, inexpensive construction and may be discarded following use with only a single cartridge, or it may be repeatedly used with other cartridges.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
114 words
A camera comprising: a. a housing, b. a lens at one end of said housing, c. a film holder at the opposite end of said housing, and d. a shutter between said lens and said film holder, e. said shutter comprising a spring-urged, rotatably mounted diaphragm having at least one aperture which is registrable, on rotation of the diaphragm, with the lens, f. a slit being formed by the housing adjacent the shutter, g. said diaphragm comprising a plurality of offset portions each of which, upon rotation of said diaphragm, alternately projects outwardly through said slit for manual actuation thereof and extends inwardly of the housing for engagement with, and actuation by, said spring.
Claim 2
Dependent Claim
114 words
A camera comprising: a. a housing, b. a lens at one end of said housing, c. a film holder at the opposite end of said housing, and d. a shutter between said lens and said film holder, e. said shutter comprising a spring-urged, rotatably mounted diaphragm having at least one aperture which is registrable, on rotation of the diaphragm, with the lens, f. a slit being formed by the housing adjacent the shutter, g. said diaphragm comprising a plurality of offset portions each of which, upon rotation of said diaphragm, alternately projects outwardly through said slit for manual actuation thereof and extends inwardly of the housing for engagement with, and actuation by, said spring.
Claim 3
Dependent Claim
74 words
A camera in accordance with claim 1, wherein: a. a partition is provided in the housing between the lens and the film holder, in spaced relation to both, b. said partition having an aperture formed therein in coaxial relation to the lens, c. said diaphragm being mounted between the lens and the partition and normally covering the partition aperture, d. said diaphragm being rotatable to register its aperture with the partition aperture and lens.
Claim 4
Dependent Claim
37 words
A camera in accordance with claim 2, wherein: a. the diaphragm and the spring which urges it are both mounted on the partition, b. the diaphragm is rotatably mounted thereon, and the spring is fixedly mounted thereon.
Claim 5
Dependent Claim
106 words
A camera in accordance with claim 3, wherein: a. the spring is positioned to be biased by engagement with the leading side of an inwardly extending offset portion of the diaphragm when an outwardly projecting offset portion thereof is manually moved a predetermined angular distance, b. said spring being thereby loaded and adapted to engage the following side of said inwardly extending offset portion in order to drive the diaphragm a predetermined angular distance at a predetermined angular speed, c. whereby the diaphragm aperture is moved into and out of registration with the camera lens and the partition aperture to provide a predetermined film exposure time.
Claim 6
Dependent Claim
106 words
A camera in accordance with claim 4, wherein: a. the diaphragm is provided with a plurality of spaced apertures which are sequentially registrable with the camera lens and partition aperture upon rotation of the diaphragm, b. said plurality of offset portions being sequentially manually engageable to move the diAphragm a predetermined angular distance and to bias and load the spring, c. thereby enabling the spring to apply successive driving forces to the diaphragm in order to cause its several apertures to move sequentially into and out of registration with the camera lens and partition aperture at predetermined angular speeds and thereby to provide predetermined exposure times.
Claim 7
Dependent Claim
46 words
A camera in accordance with claim 1, wherein: a. the housing is open at the end opposite the lens, b. the film holder being detachably secured to said open end of the housing to close said end, and c. thereby comprise one wall of the camera.
Claim 8
Dependent Claim
91 words
A camera in accordance with claim 6, wherein the film holder comprises: a. a casing which is open at the front facing the lens and closed at the back and all sides, b. said casing having a pair of tubular chambers at opposite sides thereof to accommodate a pair of film reels, and c. a film extending and sequentially movable from one reel to the other across the open front of the film casing and the open end of the camera housing for exposure through the diaphragm aperture and the lens.
