US Patent:

41997956, Apr 22, 1980

Filed:

Jun 29, 1978

Appl. No.:

5/918950

Inventors:

Alexander Hunter - Chalfont PA

Assignee:

Transaction Management, Inc. - Montgomerville PA

International Classification:

G11B 1500

US Classification:

360 93

Abstract:

This disclosure relates to a tape cartridge receiving and locking mechanism comprised of but three relatively moving parts which collectively function to both receive a magnetic tape cartridge and lock said cartridge into position during the recording and transcription of information therefrom. The combination comprises a table portion upon which the magnetic tape cartridge rides, a generally U shaped rocker arm pivotally mounted on the table, and a relatively straight spring which exerts a biasing force on the rocker arm tending to cause projections on the extremities of the rocker arm to project through cut-out portions of the table and into locking engagement with the cartridge.

Alexander Hunter - Chalfont PA

Assignee:

Transaction Management, Inc. - Montgomeryville PA

International Classification:

B65H 1702

US Classification:

242 672

Abstract:

A mechanism for taking up the slack in a continuous web being fed to the take up mechanism by independent control means. The take up mechanism is automatically switched on whenever feeding of the continuous web by the independent control means commences. The take up mechanism continues to operate as the continuous web is being fed by the independent control means. At such time as the feeding of the continuous web is terminated the automatic take up mechanism continues to take up slack in the paper web until the tension in the paper web precludes further rotation of the geared spindle upon which the continuous web is being wound. Because of the pivotal nature of the drive assembly, comprising a motor and drive gear, the motor continues to turn the drive gear causing the latter to "walk" over the now stationary driven gear and in so doing causes the housing of the motor to come into contact with and depress a microswitch thereby interrupting the flow of electricity to the drive motor. The operative forces are such that the motor housing continues to maintain the microswitch in a depressed condition until feeding of the continuous web is resumed.

Filed:

Appl. No.:

5/926315

Inventors:

Alexander Hunter - Chalfont PA

Assignee:

Transaction Management, Inc. - Montgomeryville PA

International Classification:

G11B 1500

US Classification:

360 93

Abstract:

A mechanism for establishing the requisite drive tension in a magnetic tape cartridge, and, by means of the same mechanism effecting the ejectment of the cartridge at such time as the magnetic recording or transcribing operation is complete. In an alternative embodiment designed for use in situations where the magnetic tape cartridge is inserted and ejected in the vertical plane, an auxiliary spring is utilized to supplement the tensioning and ejectment forces otherwise operative.
