Abstract

613,768. Axial-flow fans. COLLINS, A. L. July 2, 1946, No. 19713. [Class 110 (i)] A fan in which the blades 7 are separate from the hub member 2 having arms 4 extending rigidly therefrom, the blades 7 being constructed from resilient material and having cavities into which the arms '4 are fitted, is characterised in that the cavities are of smaller cross-section before fitting the blades 7 than the portions of the arms 4 which engage therein, The arms 4 may be provided with saw-teeth. or enlargements 11 as additional securing means.
