Abstract

118,546. British Thomson - Houston Co., (General Electric Co.). Jan. 15, 1918. Mounting. - A frame C carrying one or more electrically-driven fans is rotated about the axis of the support D by means of a friction disk 5, driven through worm gears 9, 10 from the fan spindle 7, engaging a non-rotatable disk 6 which is adjust able radially of the disk 5 to vary the speed of rotation. The disk 6 is carried by a screwed sleeve 23 splined on the central spindle so as to slide along the same and engaged by the screwthreaded sleeve 25, which is rotatable on the central spindle, but cannot move axially. The disk 5 is pressed against the disk 6 by a spring 16, and is driven by the pin 13 in the spindle 8 engaging the split hub of the disk 5. The gears 9, 10 allow of variation of the inclination of the fan spindles 7.
