ABSTRACT:
A transmission for a vehicle of the type having a wheel to which power is to be applied to rotate it and a drive means to provide wheel turning power, includes a cone-shaped member with concentric rings of teeth on its surface adapted to be concentrically attached to the wheel to be powered, and a drive sprocket ring encircling the axis of the cone-shaped member and having engagement means thereon adapted to cooperate with a selected ring of teeth on the cone-shaped member. A shifting means is adapted to shift the sprocket ring so that the engagement means may engage any of the rings of teeth selected. The ring of teeth selected determines the ratio of the transmission.
