ABSTRACT:
The invention relates to mechanisms for uncoupling two rotating elements. The device includes a positive clutch sliding on a rotating drive element and subjected to the action of a return spring, an energy storage spring stronger than the return spring and designed to disengage the positive clutch, a cam connected to the drive element and designed to tension the energy storage spring, a pawl capable of keeping the energy storage spring tensioned, and an electromagnet intended to actuate uncoupling and connected to the pawl so as to release the energy storage spring. The device is applicable to temporary uncoupling of two coaxial rotating elements in particular in weaving looms, in order to uncouple the crankshaft from the loom and its main motor from the dobby shaft and its auxiliary control motor.
