Control circuit for single revolution means

In a machine including driving means and means for sensing a sheet fed to the machine;

• and improvement comprising:
• a. a rotary timing cam;
• b. an actuating member movable into and out of locking engagement with the cam;
• c. a source of supply of d.c. power;
• d. first circuit means connected across the power supply and including a solenoid and a trip switch actuatable for energizing the solenoid;
• e. second circuit means connected across the power supply and including a d.c. motor and a motor switch actuatable for energizing and deenergizing the motor;
• f. the trip switch actuated in response to the sensing means sensing a sheet fed to the machine, and the driving means causing the actuating member to move out of locking engagement with the cam and actuate the motor switch for energizing the motor to drive the cam when the solenoid is energized;
• and
• g. the first circuit means including timing means for maintaining energization of the solenoid for a predetermined time period, and the timing means including a capacitor.
