  • Hand drive for blending-type gasoline dispenser
    Patent number: 4049159
    Abstract: A hand drive for manually operating a blender-type gasoline dispenser in the event of power disruption, including a crank operated shaft mounted for rotation and which is axially presettable relative to the pump drives for selectively operating either or both of the dispenser pumps. Laterally extending from the shaft are a pair of spaced pins for rotatably coupling the shaft with the drive sheave of the selected pump or pumps. Presetting the shaft axially with the pins in a first position rotatably couples the shaft via one of the pins to one sheave for high octane dispensing while the other pin and respective sheave remain disengaged. Setting the shaft in a second position rotatably couples the shaft via the other of the pins to the second sheave for low octane dispensing while the first pin and respective sheave remain disengaged.
