Abstract
1,259,367. Axial-flow fans. F. S. ANDERSEN INGENIOROG MASKINFORRETNING I.S. March 31, 1969 [April 8, 1968], No. 16840/69. Heading F1C. A fan impeller has adjustable blades 58 which assume the closed position shown when the impeller is stationary. However, when the impeller is rotated the blades are moved into their operative open positions by a pair of centrifugal weights 74 which move radially-outwardly about pivot pins 70 to partially rotate a control member 68 through pin-and-slot connections 76, 78 and thereby move the blades through arms 66. The degree of opening of the blades can be controlled by adjustable abutments 86 for the weights 74. Compression springs 82 bias the weights into their radially inner positions. The blades may instead be adjusted by an axially-movable control member. The impeller may be rotated in the reverse direction to reverse the flow therethrough. If, however, the impeller is to be rotated in one direction only the blade pivot shafts 60 may be offset from the control axes of the blades.
