A new type of gear is provided which endorses a new type of slide pin gear having a plurality of holes within which a plurality of rounded pins travel traversely. The slide pin gear travels in combination within two corresponding exterior ruffled plates as they turn. The gear provides a positive infinitely variable speed assembly. The two wheels, each having a face of each wheel with ruffles extending from the center to peripheral edge. The ruffled surfaces are flat across the diameter, and from the center to the peripheral edge, the depth of each valley is equal to the crest of the ruffles, forming a smooth blending wave into one another. The speed radio of the gears depends upon the distance between the axle centers of the slide pin gear and the corresponding pair of ruffled wheel plates. Alternately, the gear assemblies may be provided with auxiliary locking features, to insure the locking of each of the pins at the desired position for maximum interface with the ruffled wheel plates. |
