Abstract
Abstract The present invention relates to apparatus for winding and reeling webs of indefinite length and of relative narrow width such as magnet tape and motion picture film, and more specifically, a cartridge comprising a housing and a pair of spaced apart mutually parallel spindles supported rigidly by the housing, and where a pair of hubs are rotatably mounted on the spindles, each hub being driven by a selectively positioned drive wheel which is inserted into the cartridge and contacts one or the other of the hubs, depending on which direction winding is desired.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
124 words
A cartridge for the winding and storage of tape comprising: a housing having sides; a pair of spaced apart mutually parallel fixed spindles carried by one of the sides of the housing and perpendicular thereto; a hub mounted for rotation on each of said spindles; first drive means concentric with each of said spindles and fixedly attached to each of said hubs disposed and adapted to engage second drive means disposed exteriorly of the cartridge, said first drive means comprising, a flange integral with the hub, the plane of which is perpendicular to the spindle, the periphery of said flange having means for driving engagement with said second drive means; and a second hub concentric with the first hub and mounted for rotation therewith.
Claim 2
Dependent Claim
124 words
A cartridge for the winding and storage of tape comprising: a housing having sides; a pair of spaced apart mutually parallel fixed spindles carried by one of the sides of the housing and perpendicular thereto; a hub mounted for rotation on each of said spindles; first drive means concentric with each of said spindles and fixedly attached to each of said hubs disposed and adapted to engage second drive means disposed exteriorly of the cartridge, said first drive means comprising, a flange integral with the hub, the plane of which is perpendicular to the spindle, the periphery of said flange having means for driving engagement with said second drive means; and a second hub concentric with the first hub and mounted for rotation therewith.
Claim 3
Dependent Claim
120 words
A cartridge for the winding and storage of tape comprising: a housing having sides; a pair of spaced apart mutually parallel fixed spindles carried by one of the sides of the housing and perpendicular theReto; a hub mounted for rotation on each of said spindles, wherein the hub is split perpendicularly to its axis of rotation; frist drive means concentric with each of said spindles and fixedly attached to each of said hubs disposed and adapted to engage second drive means disposed exteriorly of the cartridge, said first drive means comprising, a flange integral with the hub, the plane of which is perpendicular to the spindle, the periphery of said flange having means for driving engagement with said drive means.
Claim 4
Dependent Claim
120 words
A cartridge for the winding and storage of tape comprising: a housing having sides; a pair of spaced apart mutually parallel fixed spindles carried by one of the sides of the housing and perpendicular theReto; a hub mounted for rotation on each of said spindles, wherein the hub is split perpendicularly to its axis of rotation; frist drive means concentric with each of said spindles and fixedly attached to each of said hubs disposed and adapted to engage second drive means disposed exteriorly of the cartridge, said first drive means comprising, a flange integral with the hub, the plane of which is perpendicular to the spindle, the periphery of said flange having means for driving engagement with said drive means.
Claim 5
Dependent Claim
102 words
Apparatus for winding and reeling strip material of indefinite length comprising: a base member having two spaced apart mutually parallel spindles fixed thereto; take-up and supply hubs, respectively, each rotatably mounted on one of said spindles; first drive means concentrically and fixedly attached to each of said hubs; second drive means disposed intermediate the said spindles and adapted to selectively engage the first drive means on one of the hubs; and an outer hub mounted concentrically on the said take-up and supply hubs for rotation therewith, wherein the take-up and supply hubs are split in a plane substantially perpendicular to the spindle.
Claim 6
Dependent Claim
102 words
Apparatus for winding and reeling strip material of indefinite length comprising: a base member having two spaced apart mutually parallel spindles fixed thereto; take-up and supply hubs, respectively, each rotatably mounted on one of said spindles; first drive means concentrically and fixedly attached to each of said hubs; second drive means disposed intermediate the said spindles and adapted to selectively engage the first drive means on one of the hubs; and an outer hub mounted concentrically on the said take-up and supply hubs for rotation therewith, wherein the take-up and supply hubs are split in a plane substantially perpendicular to the spindle.
Claim 7
Dependent Claim
25 words
The combination of claim 3 and further including spaced apart retainer means surrounding each of said spindles and disposed bi-laterally of the said outer hub.
