ABSTRACT:
A control head assembly which automatically locks a control lever into one of two or more selected positions, thus reducing chances of accidental disengagement. The lever is relatively stiff and is rotatable between at least two selected positions and is also movable along hinge axis. Stops carried on control head mounting and on lever permit rotation of the lever between the two positions when the stops are disengaged and prevent rotation when the stops are engaged. A spring cooperates with the lever and mounting to permit axial movement for engagement and disengagement and to hold in engagement when lever is in one of the selected positions. The stop on the lever has a particular shape which can be accepted in at least two orientations relative to the stop on the mounting.
