ABSTRACT:
The invention comprises a simple and efficient transmission for varying speed and engagement of power, comprising a planetary drive with input means driven by a prime mover's output, scheduled friction clutch means for gradually slowing and stopping rotation of an idler wheel member of the planetary drive so that as the force of the clutch is increased, power is automatically transferred from the idler wheel member to the output of the planetary drive, starting with a slow speed with high torque to a fast speed with lower torque by scheduled increments which enable rotation of the output shaft, under load resistance, without prime mover stall.
