6314. Grant, R. F. S., and Monk, B. March 15. Variable-speed and reversing gearing ; fly-wheels. -Relates to change-speed and reversing epicyclic chain gearing, being a development of the gear described in Specification No. 4589, A.D. 1905. The gear may be arranged inside a fly-wheel b secured to an engine shaft k. A cover-plate c is secured to the wheel b by bolts d, upon one of which is journaled a shaft e carrying planet sprocket-pinions e<1>, e<2>, e<3>, &c. rotatively connected. The pinion e' is geared by a chain to a sun-pinion f fast upon the driven shaft j. The pinion e<2> is geared to a smaller pinion g connected by a sleeve g<1> to a brake drum g<2>. The pinion e<3> is geared to a larger pinion h connected by a sleeve h<1> to a brake drum h<2>. A solid drive is obtained by clutching the drums h<2>, g<2> together. A second forward speed is obtained by holding the drum g<2> against rotation. When the drum h<2> is held, the shaft j is driven in a reverse direction.
