Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
170 words
A device for withdrawing a film from a magazine or the like wherein the film is wrapped about a motor-driven reel carried therein for moving the film end away from an end slot, and said magazine carries a first slot formed within the end of sAid cartridge for allowing the end of said film to project therefrom, a second, elongated slot in another end face of said cartridge, an operating plate operatively positioned with respect to said cartridge, said operating plate having a hooked projection and means for moving said plate to cause said hook projection to extend through said second elongated slot and into engagement with said film and for longitudinal movement with said second slot to force the tip end of said film through said cartridge and first slot, and an elongated slot formed within said film adjacent the free end thereof, and a normally open switch carried by said withdrawing device for selectively energizing the drive motor to cause said film slot to underlie said hook projection.
Claim 2
Independent Claim
170 words
A device for withdrawing a film from a magazine or the like wherein the film is wrapped about a motor-driven reel carried therein for moving the film end away from an end slot, and said magazine carries a first slot formed within the end of sAid cartridge for allowing the end of said film to project therefrom, a second, elongated slot in another end face of said cartridge, an operating plate operatively positioned with respect to said cartridge, said operating plate having a hooked projection and means for moving said plate to cause said hook projection to extend through said second elongated slot and into engagement with said film and for longitudinal movement with said second slot to force the tip end of said film through said cartridge and first slot, and an elongated slot formed within said film adjacent the free end thereof, and a normally open switch carried by said withdrawing device for selectively energizing the drive motor to cause said film slot to underlie said hook projection.
Claim 3
Dependent Claim
35 words
The film-withdrawing device as claimed in claim 1 wherein said motor comprises a low-torque motor to prevent tearing of the end of said film strip when said hook projection is received by said film slot.
Claim 4
Dependent Claim
81 words
The withdrawing device as claimed in claim 1 wherein said means for moving said hook projection through said second elongated slot into engagement with said film and along said second elongated cartridge slot comprises a support plate fixedly positioned adjacent said second elongated cartridge slot, an inclined, elongated slot carried by said support plate and means for coupling said operating plate to said support plate for pivotal movement with respect thereto and for movement along the length of said inclined slot.
Claim 5
Dependent Claim
141 words
The withdrawing device as claimed in claim 3 wherein said coupling means comprises first and second longitudinally spaced fins fixedly carried by said operating plate and received within said inclined slot for sliding movement therein and a recess carried by said support plate to one side of said inclined slot opposite to that of said hook projection and biasing means tending to bias one of said pins in the direction of said recess, whereby said one pin, in moving relative to said recess, causes said hook projection end to enter said second elongated magazine slot to effect engagement between the hooked end of said operating plate and said apertured film, whereupon said operating plate is free to slide along said inclined slot to cause the tip end of said film to be forcibly projected through said end slot of said cartridge.
Claim 6
Dependent Claim
38 words
The withdrawing device as claimed in claim 1 wherein said normally open motor control switch is position adjacent said operating plate such that said switch is manually closed when said operating plate is pivoted in one manual operation.
