Abstract

An engine cooling-system fan formed by combining two fan assemblies of like construction. Each fan assembly comprises a sheet-metal hub with radiating spokes, and a set of fan blades fastened one to each spoke. The hubs of both fan assemblies are riveted or otherwise joined together in axial alignment, with the two sets of fan blades arranged alternately at constant angular spacings. Preferably, the spokes of either one of the fan assemblies are offset to provide the same plane of rotation for the two sets of the blades.
