ABSTRACT:
The invention pertains to a clutch for an oscillating fan wherein the clutch may be preadjusted for producing various degrees of oscillation, but will automatically adjust to a lesser degree of oscillation if the fan movement is restrained due to the fan's encounter with a stationary object. If necessary, the fan oscillation will automatically adjust to 0° oscillation if a severe obstruction is encountered.
