Abstract
A transverse fan assembly including a plurality of elongated fan blades arranged in a cylindrical array and a plurality of axially spaced and generally aligned discs of substantially uniform diameter. Each disc defines equidistantly spaced slots concentric with and inwardly of the disc periphery for allowing the blades to loosely pass therethrough. Each blade is individually attached to a disc by a blade retainer which, in response to an individual twisting action upon the blade, releasably and individually attaches the blade to the disc under a substantially constant and independent force in a manner allowing for removal or replacement of the blade without affecting other blades in the fan assembly.
