Abstract
A manually operable, self engaging shifting lever construction which is integrally incorporated into a multi-speed transmission. The lever construction itself incorporates a stiff tension spring member which is radially deflectable from its normally straight position relative to the axis thereof. Pivotally moving the lever construction about its fulcrum produces sliding movement of an input gear cluster along an input shaft means. At predetermined locations along the input shaft longitudinally, the gear cluster becomes engageable with drive gear assemblies of an output, a drive gear cluster which is mounted on an output shaft. The flexural characteristics of the lever construction permit simple, safe shifting of the input gear cluster, without the impass normally encountered due to abutment of gear teeth.
