Abstract

22,821. S i d e - bottom, H. Dec. 14. Fans, centrifugal. Around the edge of a circular rotating plate a, a series of curved vanes or blades c are fixed. Each of these vanes is constructed with an edge c', which continues the angle or slope of the cone b with which the centre of the plate is occupied. The effect is that, when the fan is in motion, air is drawn in, as shown by the arrow, at the apex of the cone, passed along its sides, and discharged by the vanes. In a double form of fan, a cone with vanes is fixed upon each face of the plate.
