Patent attributes
A fan (10) is disclosed having an electric motor (13) which rotatably drives an annular array of blade irons (14) each having a blade (15) mounted thereto. Each blade iron has a motor mounting portion (21) configured to be coupled with the electric motor for rotation. The motor mounting portion has an arcuate, vertical wall (26) and a horizontal flange (27). The horizontal flange has a first mounting hole (28) and an oblong second mounting hole (29). A first mounting screw (31) having a first bushing or bearing (32) thereon passes through each first mounting hole and into a threaded mounting hole (34) in the motor (13). Similarly a second mounting screw (35) having a second bushing or bearing (36) thereon passes through each second mounting hole and into a threaded mounting hole (37) in the motor. With this configuration the blade iron can pivot relative to the motor.
