Fuelling station for car racing track - drives controlling fuel delivery indicators on control columns and actuated by car stopping on track section with conductor rails

摘要

The supply of fuel is controlled and indicated by a column with two rotary scales indicating the quality of fuel delivered. Each scale carries a toothed ring with a friction disc and a set of drive gears. At two points of the end of travel of the disc are two switch contacts which disconnect the operating button from the drive motor when the tank is full. They also connect the motor when the empty tank arrives at the control position. The vehicle stops on a track section with conductor rails which provide signals to initiate the filling operation. The column has two sliding buttons controlling the rate of delivery, each controlling a resistance in a circuit controlling the speed of the motor driving the rotary scale.
