Abstract
Abstract A cartridge to be loaded with a length of film or other strip material is adapted to be positioned in a sound motion picture camera, projector or other sound recording or reproducing apparatus. The cartridge has an open area across which the strip material extends so that the strip material in this area can cooperate with the sound mechanism of the apparatus. A guide finger is positioned with respect to the open area in the cartridge to (1) contain the strip material within the cartridge body and guide the film into position relative to the sound mechanism during insertion of the cartridge into the apparatus, (2) protect the film from damage during such insertion, and (3) avoid picking and possibly hand-damage to the film during such insertion.

Claim 1
Independent Claim
204 words
In a cartridge for handling a length of film or other flexible strip material, the cartridge having an end wall and first and second side walls adjacent the end wall, the cartridge having an aperture located in the end wall and the first side wall in the cartridge, means defining a path for the film through the cartridge and across the aperture, the cartridge being usable with sound apparatus engageable with the film in the cartridge through the aperture for recording sound on the film and for advancing the film through the cartridge, the improvement comprising: a guide finger comprising a base portion connected to the second side wall and a relatively narrow prong portion projecting from the base portion, the finger projecting substantially entirely across the portion of the aperture in the end wall and between the ends of the aperture in the end wall so that the outermost portion of the finger protects the film from possible twisting or damage that might occur in the absence of the finger during positioning of the film relative to the sound apparatus, the finger being positioned with respect to the film path across the aperture to limit outward bowing of the film through the aperture.

In a cartridge for handling a strip of film, the cartridge having an end wall and first and second side walls adjacent the end wall, means defining an aperture in the end wall and the first side wall, the cartridge having means defining a path for the strip of film through the cartridge and across the aperture, the path defining means effecting a bend in the film adjacent the aperture so that the film tends to project through the aperture in the end wall, the cartridge being positionable in a camera having sound apparatus engageable with film in the cartridge through the aperture for advancing the film through the cartridge and recording sound onto the film, the improvement comprising: a guide member connected to the second side wall and projecting toward the first side wall by a distance substantially equal to the width of the end wall, and the guide member being separated from the first side wall by the aperture in the first side wall, the guide member being positioned with respect to the path for the film across the aperture to hold the film against bowing outwardly through the aperture in the end wall and to guide the film into position with respect to camera sound apparatus during insertion of the cartridge into a camera, the guide member comprising a finger having a base portion connected to the second wall and a narrower prong portion projecting from thE base portion, the finger being sufficiently long to underlie substantially the entire width of the film path across the aperture in the end wall, the surface of the finger facing the path for strip material being substantially coplanar with the end wall.
