ABSTRACT:
Gasoline dispensing apparatus with cost and volume registers composed of banks of rotary electromagnetic indicators, each having a two-coil electromagnetic stator for indexing a respective rotary indicator wheel, and a drive circuit for accumulating the cost and volume of fuel delivered and for indexing the indicator wheels of the banks thereof for registering the cost and volume of fuel delivered. The drive circuit is operable for indexing each indicator wheel with multiple step indexing cycles providing a predetermined multiple step energization sequence of the two coils of the electromagnetic stator. The drive circuit is operable for resetting the counter wheels by indexing the wheels in the forward direction to their "9" positions and then nine counts in the reverse direction to their "0" count positions where the wheels are retained against further reverse rotation by one-way locking pawls.
