Abstract

650,811. Two-speed gear. SCINTILLA, Ltd. Sept. 25, 1946, No. 28671. Convention date, Sept. 25, 1945. [Class 80(ii)] In a change-speed gearing contained in the pulley of a motor, a hollow spindle is secured to one bearing of the motor to surround the driving shaft and carry the gearing, the spindle containing a coupling member rigidly secured to the driving shaft and engageable with either the gearing or the pulley. The shaft 5 of a motor 1 carries a coupling member 4 rotating within a stationary hollow shaft 3 secured to the motor casing. The member 4 drives a coupling device 7 through a resilient bundle of spring blades 6, the device being axially movable, when the spring-loaded detent 21 in the knob 17 is released, to engage or disengage the dog teeth 8 on the device with the corresponding teeth 14 in the bore of a driven pulley assembly 15. The internal teeth 12 of the assembly 15 are similarly engageable by the external teeth of an eccentrically mounted internally and externally toothed planet gear 11, the internal teeth of which are engageable with teeth on a stationary sun gear 10 rigid with the shaft 3. In operation the coupling device 7 is moved to the right to engage the teeth 8, 14 for direct drive, and to the left to engage the planet gear 11 for a reduced ratio drive.
