Abstract

577,347. Clutches. GENERAL ELECTRIC CO., Ltd., BONEL, B., and WALLACE, D. M. Oct. 24, 1941, No. 13699. [Class 80 (ii)] [Also in Group XXXV] An external fan cooling the casing of a watertight motor is driven by the shaft but is coupled to it in such manner that if the motor becomes submerged and the torque required to drive the fan is thereby increased, the drive discontinues. In the form shown the hub 2 of the fan 3 is carried by the outer race of bearing 4 the inner race being on a sleeve secured to the shaft 1. A pawl 5 pivoted at 6 on the said sleeve has a projection 9 engaging a groove 10 in the hub 2 for transmitting the drive when the fan operates in air and the pawl is held in position by balls 7 spring-pressed into depressions in the pawl. When this spring pressure is overcome by increased torque due to the fan being immersed in water the pawl is moved out of the slot 10 and the fan drive interrupted. The pawl may be returned to the driving position as the motor slows down by movement of a pivotal weight no longer subject to centrifugal force.
