Patent attributes
A follower assembly includes a follower mounted on an axle with the axle being coupled to a carrier that is pivotable relative to the frame about a pivot axis. The follower assembly has a locked position in which the pivot axis and axle are positioned relative to each other in a locked over-center position. In the locked over-center position the driver is pinched between the follower assembly and the flywheel subjecting the driver to a pinch force when the driver is in the stall position. When the driver is in the stall position and the follower assembly is in the locked over-center position, pivotal movement of a stall release lever toward the release position forces the follower assembly out of the locked over-center position toward the reverse over-center position in which the relative positions of the pivot axis and axle are reversed and the pinch force is released.
