Abstract: A gear train mechanism with a motor input, a planetary clutch and an output shaft with load responsive clutch disengagement means is provided by a toothed outer casing on the planetary clutch with a detent to engage the teeth mounted on a pivotable arm. The arm is retained in the clutch engaging position by a solenoid. The solenoid core is mechanically linked to the arm through a resilient linkage. The solenoid is connected to a suitable e.m.f. with a normally open microswitch which is held in the closed position by a second detent on the arm. Excessive loading overcomes the resilient linkage between the core and the arm, permitting the arm and its clutch detent to rock from engagement with the toothed clutch casing. This displacement opens the microswitch, deactivating the solenoid and releasing the planetary clutch. The mechanism is particularly useful for any automatic control function where it is desired to have manual override provision which will disengage the automatic control. It is particularly useful in the linkage between the rudder and the power unit of an automatic pilot. Another application would be in the mechanical linkage between a valve actuation motor and a valve for remotely controlled valves such as underwater valves.
