of braking of the basket between each reverse rotation of the motor is not critical because of the relative slow speed of oscillation during the time the basket is cyclically reversed the inertia of the moving basket causes a relatively small torque and the dynamic braking of the motor at the end of each direction of rotation is acceptable in operation of the machine during the high speed extraction cycle the motor 48 in combination with the mechanical transmission system provides a higher speed for example 600 rpm unidirectional rotation at this relatively high speed the inertia of the rotating means creates a motion which is difficult to stop within an acceptable time period at the termination of the extraction cycle the motor 48 is electronically braked to terminate basket rotation the employment of a speed reduction coupling in the form of the worm 54 and worm wheel 56 between the motor and basket provides a secondary braking action which supplements the braking action of the motor when applied to the basket in effect the energy of the rotating mass is converted to frictional energy in the transmission through the inability of the worm wheel 56 secured to the basket drive shaft 40 to drive the worm 54 secured to the motor drive shaft 50 as the motor.
