Abstract
Abstract A family of multispeed constant-mesh-gear reversible transmissions has a basic structure that includes five drivingly connected shafts, with all of these shafts lying in a common plane. A plurality of gear trains selectively drives the output shaft at various speed ratios, and pluralities of clutches are used for connecting several of the shafts and for connecting various ones of the gears to various shafts for conjoint rotation therewith. Several embodiments of connecting means are used for connecting the output shaft with at least one of the several gears.
