Abstract

263,003. Gilbert, N. W., Jacoby, H. C. E., and Jabet, A. E. March 22, 1926. Mounting.-A table fan and motor is mounted on trunnions A on a swivelling fork a<2>. A slow speed shaft d is carried by the motor casing and is driven through reduction gearing and shaft b' from the motor. A crank g is pivoted upon the shaft d and has a ball-joint connection with a fixed pivot f<2> whereby the motor and fan are caused to gyrate. The pivot g' may be carried by a screw in the end of the shaft d so that it can be moved laterally and the orbit of the fan changed thereby. The shaft d may be inclined to the motor shaft and their axes may intersect at the centre of motion of the motor. The slow motion shaft is driven through a clutch, Fig. 4, which comprises a loose worm wheel b<6> and friction plates o<6>. When a nut o on the end of the shaft is screwed to the left, a spring o<1> presses the plate o<6> and the wheel together and the drive is effective. When the nut is screwed to the right, the friction drive is stopped, and if the nut is screwed into contact with the cover o<2> the unit is locked from gyratory movement.
