Abstract
A stock reel having a variable speed electric reel drive motor and a speed control potentiometer operated by a stock loop control arm for producing a variable control voltage correlative with the angular position of the control arm. The control voltage from the control potentiometer is compared with a reference voltage and an input voltage correlative in amplitude with the difference between the control voltage and the reference voltage is applied to a motor control unit to drive the motor when the control voltage exceeds the reference voltage. The reference voltage is selectively adjustable to vary the angular position at which the control voltage exceeds the reference voltage, to thereby adjust the operating angle of the control arm. The amplification of the input voltage applied to the motor control unit is adjustable to vary the range of control arm movement required to produce a preselected change in motor speed. Power switch means control the application of voltage to the control voltage divider and the reference voltage divider to enable payout and rewind of stock from either side of the stock reel.
