ABSTRACT:
An arrangement for isolating engine noises and vibrations or the like from the blades of a ceiling fan include a blade-mounting ring, to which the blade irons are directly attached, and a plurality of elastomeric grommets or bushings carried on the ring. Partially threaded studs extend through the grommets and into the rotor cage to suspend the blade-mounting ring slightly below the rotor cage by the transfer of weight of the blades through the rubber grommets. The blade-iron feet enclose the grommets and prevent the inadvertent withdrawal of the stud members therefrom.
