Abstract
Gasoline dispensing apparatus with cost and volume registers composed of banks of rotary electromagnetic indicators, each having an electromagnetic stator with a drive coil for indexing a respective rotary indicator wheel and a sensing coil for sensing wheel rotation and direction, and an indicator operating circuit for accumulating, and for indexing the indicator wheels for registering, the cost and volume of fuel delivered. The sensing coil is employed for monitoring and verifying wheel rotation and each indicator wheel is indexed by energizing the respective drive coil in the appropriate direction and for an optimum interval controlled by the respective sensing coil. The indicator wheels are reset in the reverse direction to their '0' count positions, where the wheels are retained against further reverse rotation by one-way locking pawls, and are then indexed in the forward direction one step and in the reverse direction one step and then through one additional drive coil energizing cycle to verify that the indicator wheels are at their '0' positions.
