1. a random lottery number generating device comprising in combination:

  • (a) at least two random number generators for generating a random number output, each generator including a free running clock, a resistor-capacitor circuit associated with said clock for generating an RC time constant and a corresponding repetition rate, and a counter, said clock having a clock output which is a train of square waves, said clock output linked to and driving said counter which has a counter output which advances sequentially each time said clock output changes state, whereby the repetition rate of said at least two random number generators is determined by its associated resistor-capacitor RC time constant with the RC time constant of each of said at least two generators being different such that when activation of said clock of each of said at least two generators occurs and continues for an arbitrary time interval, said clock of each generator will output an arbitrary and random number of pulses to said counter to which it is linked, thereby causing said counter of each generator to advance to a different arbitrary count;

    (b) means for setting an upper and a lower count limit for said at least two random number generators linked to said counter within each generator; and

    (c) means for displaying each counter output.
