Abstract

581,956. Screw fans. COLLINS, J. N. June 12, 1944, No. 11171. Drawings to Specification. [Class 110 (i)] An axial flow fan comprises vanes each consisting of a number of wires or rods extending between the hub and peripheral rim of the fan and covered with a wrapping of flexible material such as thin strip metal, wire, insulating tape, string, or the like. The pitch of the vanes may vary from the inner to the outer ends.
