A clutch mechanism suitable for connecting a rotatable member to an output shaft of a motor, which mechanism comprises a body which is attachable to the output shaft and a resilient arm, one end of which is fixed to the body the other end of which is capable of engaging the rotatable member or part thereof, wherein the body is capable of gripping the output shaft in secure frictional contact to transfer rotational drive from the output shaft to the rotatable member only when the rotatable member is not restrained against rotation.

Fan with air directing grille

A box fan comprising a box-like structure containing an electric motor and a fan blade assembly operable by the motor, which structure consists of a front section and a rear section forming a box having front and rear openings which are interconnected to form a duct through said box, the fan blade assembly being positioned for causing air flow through the duct when the motor is operating, wherein the two sections are held securely together by a locking means including external resiliently operable disguised clamps which are disposed transversely of the interface between said sections.

Box fans

This specification discloses an improved means for adjusting the movement of a gyratory head fan comprising a turntable driven by the fan motor and supporting an adjusting mechanism which changes the position of a socket member for the ball of a gyratory linkage with respect to the axis of rotation of the turntable. The adjusting mechanism comprises a rim which may be held against rotation relative to the turntable, lugs on the rim which engages lugs on a rotatably mounted member incorporating the socket such that the member is rotated to change position of the socket. The rim may be held against rotation by means of a plunger which engages projections on the rim. Spring loaded pawl means may be provided to hold the member in several predetermined positions to provide different modes of operation.
