Abstract
Abstract A multiple product gasoline dispensing pump with two multiple product gasoline delivery subsystems independently operable from opposite sides of the pump for selectively dispensing a plurality of different grades of gasoline and for computing the cost of the gasoline dispensed in accordance with the established unit volume price for the selected grade. A single-price programming unit comprising three rotary price decades for each grade is provided for both delivery subsystems for establishing and posting the unit volume prices. The price decades are coaxially mounted for rotation about a vertical axis and each comprises a number wheel with two numeral sequences of 0-9 providing for posting the unit volume prices on the opposite sides of the pump. The price decades have binary switches providing encoded signals of the established unit volume prices and are connected via a selector circuit for setting each delivery subsystem to compute the cost of gasoline dispensed in accordance with the established unit volume price for the selected grade.
