Abstract
Abstract Taxi vehicle fare measuring apparatus where impulses proportional to a waiting time and/or distance are supplied to a binary multiplier whose multiplication factor is selected by the driver at the time the taxi is hired. Several banks of binary switches are provided to calibrate the meter after its installation in accordance with a corresponding number of different established fare rate schedules. The preadjustment of the binary switches allows for accurate calibration of the meter taking into consideration such factors as speedometer gear ratios and tire wear, and the number of banks of binary switches allow for rate schedules to take in such variable factors as number of passengers, waiting time, or special fare rates for various geographical locations or time of day. The output pulses from the multiplier are supplied to a binary counter which controls an indicating device for producing a display of the fare. Additional banks of binary switches may be provided to preset the counter to a beginning condition corresponding in amount to a fixed charge.
