ABSTRACT:
A single lever control head assembly (10) for dual-position-shifting of a transmission and dual position throttle control of a motor includes a support housing (12) and a single lever (62) pivotally supported in a bore (142) in a cylindrical housing (12) for rotation about a lever axis (A). The bore (142) and its axis (A) are offset from the center axis of the cylindrical housing. A throttle arm (16) is rotatably supported by the housing (12) for pivotal movement about a throttle arm axis (B). The transmission arm (20) has a cylindrical female portion (22) rotatably supported by the housing (12) for pivotal movement about a transmission arm axis (A). The transmission arm axis and the lever axis are coaxial. A first connection (26) is disposed within the female portion of the transmission arm (20) and is rotatable about the transmission arm axis for pivoting the transmission arm (20) in an arc about the transmission arm axis to the transmission-engaged position during a first portion of pivotal movement of the lever (62) from the neutral position to either of the transmission-engaged positions. The first connection (26) also maintains the transmission arm (20) in the transmission-engaged positions upon continued movement of the lever (62) to either of the full throttle positions and returns the transmission arm (20) to the neutral position with the lever (62).
