Abstract
Abstract A wide screen format Super 8mm motion picture system is provided in which standard Super 8 film cartridges are used. The frame size is the same width, but one half of the height of standard Super 8 frames. The system uses two pull-down claws, each claw pulling the film one half of the distance that it is normally moved in a standard Super 8 system. The shutter is coordinated with the pull-down claws such that the film is exposed after each claw has moved the film.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
218 words
A super 8 motion picture system which is compatible with a conventional Super 8 cartridge comprising: a. a pull down Claw means comprising a body member having first and second claw members integral with said body member, said claw members spaced longitudinally on said body member and separated from each other by a distance equal to one half the distance between sprocket holes of a Super 8 film for engaging a film in said cartridge and pulling said film wherein each claw member pulls the film the distance of one half of a conventional Super 8 frame; b. drive means directly coupled to said pull down claw means, said drive means comprising a drive wheel and means mounting said body member eccentrically on said drive wheel such that for each revolution of said drive wheel said claw means travels a distance equal to one half the distance between sprocket holes of a Super 8 film and returns; and, c. shutter means coordinated with said pull down claw means for exposing said film after it has been pulled by one of said claw members, whereby each frame of said film covers one half of the area of a frame in a conventional Super 8 film thereby doubling the running time of the film and creating a wide format frame.
