Abstract

1,048,828. Axial-flow fans. FOLKES BELTING CO. Ltd. July 27, 1964 [Aug. 1, 1963], No. 30505/63. Heading F1C. A radial bladed fan for cooling engines of road vehicles, comprises a hub disc 10 having at least two stiff arms 11 extending outwardly therefrom, and blades 12 trailing from the arms and either formed of flexible resilient material, or resiliently connected to the arms so as to enable the blades to move to a lesser pitch as the rotary speed of the fan increases. The blades 12 may be of rubber or spring steel directly connected to the arms 11, or of rigid sheet metal connected to the arms by flexible resilient strips of rubber, spring steel or other suitable material. The radially inner ends of the blades 12 may be floating or, as shown, connected to the hub 10 so that only the outer part of each blade will vary in pitch. The blades 12 may be connected to the arms 11 by hinges and biased to their maximum pitch position by tension or torsion springs. During high vehicle speed the blade pitch can increase enabling the fan to windmill and thereby evolve power.
