Abstract

897,814. Axial-flow fans. HUBER, H. L. May 25, 1960 [Jan. 18, 1960], No. 18534/60. Class 110 (1). [Also in Group XXVII] A reversible fan for the cooling of internalcombustion engines, particularly those of tractors, bulldozers, and the like comprises a hub having a cylindrical ring 16 and a radially inwardly-directed flange 17 to which a pulley 27 is attached by studs 28 engaging tapped holes 30, the ring 16 having on its inner and outer peripheries aligned inwardly and outwardlydirected radially extending circumferentiallyspaced bosses 18, 15 bored to receive the shafts 21 of the fan blades 13. Each inwardlydirected boss 18 has at its inner end two pairs of diametrically opposite notches and each shaft 21 has a transverse pin 20 the projecting ends of which engage one or the other of the pair of notches under the force of a spring 24 surrounding the shaft 21 and urging the blade outwardly. The springs are located between the ring 16 and washers 25 adjacent the inner ends of the blades. The ends of pins 20 project far enough beyond the bosses 18 to engage the flange 17 with one end when in one pair of notches and to engage the flange 17 with the other end when in the other pair of notches. The blades 13 are pushed inwardly against the springs 24 to reverse them. A dust cap or plate 35 is secured to the ring 16 by screws 36.
