Abstract
624,827. Screw fans. MADER, E. A., and SPARGO, J. July 10, 1947, No. 18324. Convention date, June 16, 1943. [Class 110(i)] An impeller comprises blade supports extending outwardly from the hub, the blades being pivoted on the supports for movement between a position of effective impelling pitch and a position of zero pitch and the supports being yieldably urged .from a position transverse to the'impeller axis. The blade supports comprise rods 6 hinged on a plate 5 carried by the hub 4. When the impeller is stationary, springs 17 hold the rods 6 in the inclined position shown in Fig. 2, with the blades 11 resting against stops 18 projecting from a spider 16. The blades overlap slightly in this position. Flanges 26 carried by the blades prevent leakage between the hub and blades. When the impeller is running, centrifugal force brings the rods 6 into a position transverse to the impeller axis. Stops 20 carried by the hub 4 then engage the blades to one side of their pivot rods and turn them into the impelling position shown in Fig. 4.
