faster than the speed of rotation of the ring 19. This
tendency on the part of the roller 8 to rotate the ring 37 faster
than the ring 19 is overcome by the rotation of the ring 19 by
the roller 7, said ring 19 and roller 7 restraining the ring
37 from rotating faster than it is rotated by the roller 7 and
ring 19. As the rollers 18 are fixed against epicyclic
movement, said restraining force on the ring 37 will set up an
epicyclic movement of the interposed or idler rollers 21
around the driving roller 8. This epicyclic movement will in
turn be imparted to the retainer 24 and hence to the slow
speed shaft 27 to which said retainer is keyed. The ratio of
speed between the slow speed shaft 27 and the high speed
shaft 6 will thus be dependent upon the varying ratios
between the two trains of traction or adhesion members.
The above-noted disclosure of Batchelder of the advantages of toothless driving
and driven members over toothed driving and driven members (or gears) would have
provided suggestion to one of ordinary skill in the art to replace the toothed gears of the
simple planetary gear mechanism of Minegishi's speed transmission unit (reduction
portion C) with toothless rollers in order to eliminate the disadvantages of toothed
driving and driven members, such as noise and vibration and the cost of cutting gear
