Abstract

A mechanical disconnect mechanism for an aircraft engine driven constant speed drive unit where the driving shaft (14) and the driven shaft (18) are drive connected by toothed clutch members (16,24). The disconnect involves a cam (38) which causes a sleeve (22) to slide axially by a distance sufficient to disconnect the clutch teeth by engagement with a pawl (42) that is normally held in an inactive position but released under emergency conditions.
