Abstract
Abstract A drive mechanism for a tape deck and the like comprising a drive cylinder connected with driving means. A rotatable load cylinder is spaced from the drive cylinder and is adapted to be rotated in the same direction as the drive cylinder. A movable bracket rotatably supports a clutch cylinder which is adapted to be moved into contact with both the drive and load cylinders by the bracket whereby the reaction forces between the cylinders drive the clutch cylinder into further intimate contact with the drive and load cylinders. Moving means is provided to effect movement of the bracket.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
164 words
A drive mechanism for a tape-transport system including a drive cylinder connected with driving means for rotating said drive cylinder in a first direction, a rotatable load cylinder in spaced relation to said drive cylinder, each of said drive and load cylinders having respective axes which are substantially parallel and in spaced relationship to each other, tape moving means comprising a capstan connected to said load cylinder, a movable bracket, an intermediate clutch-cylinder rotatably supported on said movable bracket and adapted to be moved into intimate contact with both of said drive and load cylinders when said bracket is moved to a first position to rotate said load cylinder in said first direction when said drive cylinder is rotated in said first direction by said driving means, selectively operable operating means for moving said bracket to said first position, and biasing means for biasing said bracket away from said first position for normally maintaining said clutch cylinder spaced from said load and drive cylinders.
Claim 2
Dependent Claim
164 words
A drive mechanism for a tape-transport system including a drive cylinder connected with driving means for rotating said drive cylinder in a first direction, a rotatable load cylinder in spaced relation to said drive cylinder, each of said drive and load cylinders having respective axes which are substantially parallel and in spaced relationship to each other, tape moving means comprising a capstan connected to said load cylinder, a movable bracket, an intermediate clutch-cylinder rotatably supported on said movable bracket and adapted to be moved into intimate contact with both of said drive and load cylinders when said bracket is moved to a first position to rotate said load cylinder in said first direction when said drive cylinder is rotated in said first direction by said driving means, selectively operable operating means for moving said bracket to said first position, and biasing means for biasing said bracket away from said first position for normally maintaining said clutch cylinder spaced from said load and drive cylinders.
Claim 3
Dependent Claim
73 words
A drive mechanism as in claim 1, and a shaft, said bracket comprising a pair of spaced arms connected together at one end and having aligned bores at the respective other ends of greater diameter than said shaft and receiving said shaft therethrough whereby said spaced arms are rotatable and shiftable on said shaft, and mounting means on said arms intermediate the ends thereof for rotatably mounting said clutch cylinder between said arms.
Claim 4
Dependent Claim
50 words
A drive mechanism as in claim 2, in which said moving means comprises a solenoid having a movable plunger, and a spring connecting said plunger to the end of said arms remote from said shaft whereby the energization of said solenoid causes movement of said bracket to said first position.
Claim 5
Dependent Claim
27 words
A drive mechanism as in claim 1, in which said drive and load cylinders are fabricated from neoprene and said clutch cylinder is fabricated from stainless steel.
Claim 6
Dependent Claim
19 words
A drive mechanism as in claim 1, wherein said drive, load and clutch cylinders are mouNted to be coplanar.
