Abstract
Abstract A cartridge for a strip of flexible material, preferably film, adapted for use with a projector having automatic feed-out means, basically comprising a reel receptacle and a cover. The receptacle has a substantially planar back portion. The cover fits over the receptacle to substantially enclose a reel, and has a substantially planar front portion. A feed-out aperture is provided in the cartridge to permit the entry of feed-out means into the cartridge and the egress of flexible strip material out of the cartridge. An arcuate guide extends within the cartridge from one end of the feed-out aperture annularly within the reel receptacle to the opposite end of the feed-out aperture and is positioned to penetrate the space between the flanges of the reel. Locking tabs and apertures are provided to interlock several cartridges together in a stacked relationship and for attaching the cartridge to the projector. Additional mounting and positioning elements are also provided.

156 words
In a cartridge which has a reel receptacle for receiving a coil of flexible strip material on a reel and a cover for said reel receptacle and which is adapted for use with automatic strip feed-out means, the combination comprising: means forming an aperture in said cartridge to permit the entry of feed-out means into said cartridge and the egress of flexible strip material out of said cartridge; and guide means extending within said cartridge from one end of said aperture annularly about the central interior of said reel receptacle to the opposite end of said aperture and positioned to penetrate the space between the flanges of the reel for maintaining the flexible strip material within the diameter of the reel flanges except in the region of said apertures, said guide means having a flexible end position to facilitate insertion of the reel into the reel receptacle and removal of the reel from the reel receptacle.
Claim 2
Dependent Claim
156 words
In a cartridge which has a reel receptacle for receiving a coil of flexible strip material on a reel and a cover for said reel receptacle and which is adapted for use with automatic strip feed-out means, the combination comprising: means forming an aperture in said cartridge to permit the entry of feed-out means into said cartridge and the egress of flexible strip material out of said cartridge; and guide means extending within said cartridge from one end of said aperture annularly about the central interior of said reel receptacle to the opposite end of said aperture and positioned to penetrate the space between the flanges of the reel for maintaining the flexible strip material within the diameter of the reel flanges except in the region of said apertures, said guide means having a flexible end position to facilitate insertion of the reel into the reel receptacle and removal of the reel from the reel receptacle.
Claim 3
Dependent Claim
71 words
The combination defined in claim 1 wherein said aperture is configurated to have a first portion of width dimension less than the spacing between the flanges of the reel for guiding entry of feed-out film engaging means into the space between the flanges of the reel and a second portion contiguous with said first portion but of greater width dimension to permit egress of the flexible strip material from said cartridge.
Claim 4
Dependent Claim
62 words
The combination defined in claim 1 further comprising means forming a second aperture in said cartridge for receiving a rewind drive puck, said guide means for at least the extent of said second aperture opening being entirely within the diameter of the flanges of the reel to permit the drive puck to contact the flange rim to rotate said reel for rewind.
Claim 5
Dependent Claim
124 words
In a cartridge for containing a coil of flexible strip material on a reel and having a substantially planar back portion, a substantially planar front portion, and a substantially planar bottom portion, the combination comprising: means forming an exit opening in the bottom portion of said cartridge to permit the egress of flexible strip material out of said cartridge; a plurality of latching tabs protruding from the back portion of said cartridge; and means forming a plurality of compatibly positioned and configurated latching tab receiving apertures in the front portion of said cartridge for enabling plural cartridges to be latched together in a stacked relationship wherein each of said stacked cartridges is operable to enable said flexible strip of material to be removed therefrom.
Claim 6
Dependent Claim
124 words
In a cartridge for containing a coil of flexible strip material on a reel and having a substantially planar back portion, a substantially planar front portion, and a substantially planar bottom portion, the combination comprising: means forming an exit opening in the bottom portion of said cartridge to permit the egress of flexible strip material out of said cartridge; a plurality of latching tabs protruding from the back portion of said cartridge; and means forming a plurality of compatibly positioned and configurated latching tab receiving apertures in the front portion of said cartridge for enabling plural cartridges to be latched together in a stacked relationship wherein each of said stacked cartridges is operable to enable said flexible strip of material to be removed therefrom.
Claim 7
Dependent Claim
28 words
The combination defined in claim 4 wherein said latching tabs and said latching tab receiving apertures are each oriented in a plane substantially perpendicular to said bottom portion.
Claim 8
Dependent Claim
48 words
The combination defined in claim 4 further comprising: positioning ribbing protruding from the back portion of said cartridge; and means forming compatibly positioned and configurated positioning ribbing receiving grooving in the front portion of said cartridge for stabilizing stacked plural cartridges against movement with respect to one another.
Claim 9
Dependent Claim
162 words
In a film cartridge which has a reel receptacle for receiving and circumferentially encompassing a coil of film on a reel and a cover for said reel receptacle and which is adapted for use with a projector having a film feed-out mechanism, the combination comprising: means forming an aperture in an edge portion of said cartridge to permit the entry of said feed-out mechanism into said cartridge and the egress of film from the cartridge; and a guide element extending within said cartridge from one end of said aperture annularly about the central interior of said reel receptacle to the opposite end of said aperture and positioned to penetrate the space between the flanges of the reel for maintaining the film within the diameter of the reel flanges except in the region of said aperture, said guide element having a flexible end position to facilitate insertion of the reel into the reel receptacle and removal of the reel from the reel receptacle.
