Abstract
706,527. Expanding-pulley gear. CARTER BROS. (ROCHDALE), Ltd., and DEAN, F. Sept. 22, 1952 [Feb. 14, 1952], No. 3927/52. Class 80 (2) One flange 3 of an expanding pulley is.axially moved positively in both directions relative to the axially immovable other flange 4 by relative rectilinear movement between the whole pulley and an inclined bar 12 having an elongated slot 18 in which slides the reduced part of a block 16 in which bears the external peripheral surface of a boss 5 of the movable pulley-flange 3, as by a ball or roller bearing 20. Positive axial separating movement of the flange 3 is provided by dovetailed tongue-and-groove engagement 17 between the block 16 and bar 12, and/or by an end-disc 23,attached to the block 16, and may be assisted by springs. Either the inclined bar 12 or the pulley may be moved, the other being stationary. In Fig. 2, the variable driving pulley is carried on the shaft 2 of a motor 1 which, to vary the effective pulley-diameter, is traversed on base-guides 9, parallel or inclined to the plane of the V-belt 27, by an adjusting screw 29, to cause the block 16, supporting the movable pulley-flange 3, to ride along the inclined linear or curved face 14 of bar, 12, which is carried on a fixed pillar 11. The axis and diameter of the output pulley '25 are invariable. In Fig. 4 (not shown) the movable flange 3 slides directly on the shaft 2. In Fig. 5 (not shown) the inclined bar 12 is arranged between the pulley and motor and adjusts the inner flange. In Fig. 6 (not shown) a variable output pulley, rotating on a fixed axis, is adjusted by bodily movement of an inclined bar secured to the motor, which is moved bodily, as before, but now carries an invariable input pulley. In Fig. 7 (not shown) the outer flange of the input and inner flange of the output pulleys are simultaneously moved axially in the same direction on fixed axes by bodily movement of two permanently connected inclined bars.
