Abstract

Abstract A cartridge adapted to contain a standard reel of processed motion picture film or other strip material has two cartridge parts, each of which includes a circular sidewall and a semicircular edge-wall extending perpendicularly from and about a peripheral portion of the sidewall. The parts fit together in mating relationship with the sidewall of one part being received in a groove defined by the edge-wall of the other part, to form the chamber for the reel of film or other strip material.

Total Claims: 4
Claim 1
Independent Claim 211 words
A cartridge mountable on a motion picture projector or the like having a spindle adapted to project into the cartridge, the cartridge being adapted to receive a roll of motion picture film or the like, the cartridge comprising: two separable cartridge parts each of which has a sidewall and an edge-wall, the edgewall of each part being attached to and projecting from a first peripheral portion of the sidewall of that part in a direction generally toward the sidewall of the other cartridge part, each edge-wall having an elongate groove therein facing toward the other edge-wall, said grooves being separated from the edge portion of the respective edge-wall opposite from the respective sidewall by a thin lip, and a second peripheral portion of each sidewall comprising two shoulders jointly defining a stepped configuration with one of shoulders of each part fitting into the groove in the edge-wall of the other part and with the other shoulder of one part substantially abutting the lip on the edgewall of the other cartridge part, thereby to form a seal between each sidewall and the edge-wall of the other cartridge part, and at least one sidewall having an opening therethrough through which a projector spindle can project for supporting a film roll within the cartridge.
