  • Patent number: 4850804
    Abstract: An electric fan has a universally adjustable mounting which includes a vertical stem rotatable in a pedestal, and a pair of support joints extending above the stem and pivotal in mutually perpendicular planes. It is therefore possible to position the fan in lateral displacement from the stem, such that its back thrust creates a torque force tending to rotate the stem. The stem at its lower end has a base plate parallel to the pedestal. A pair of ball-and-spring mechanisms located between the base plate and pedestal permit the stem to be manually rotated to a selected position of adjustment where the balls engage a corresponding pair of holes. Yet the spring strength is sufficient to resist the torque produced by operation of the fan.
