ABSTRACT:
A twin lever control assembly for controlling two inter-related functions, such as a clutch/gearbox unit and a throttle of a marine power unit, has an interlock to permit movement of one lever only if the remaining lever is in a particular position. The assembly has an interlocking shaft fitted for movement between two connecting members which rotate with rotation of the respective lever. The shaft has a length greater than spacing between opposed faces of the connecting members, and is spring-urged towards the first connecting member. The connecting members have sockets to receive adjacent ends of the interlocking shaft to prevent movement of the receiving connecting member, the shaft being forced into the socket by either the spring force, or by a camming effect between the first member and the shaft.
