A disengageable master carrier assembly for a motor driven drapery is provided, having a master carrier block section and a locking block section. The locking block section has entrance ramps and a detent pocket sized to receive an engagement member mounted to the master carrier block section. The master carrier block assembly has a support arm for supporting a leading edge of drapery fabric, the support arm being supported by a first resilient member. The engagement member is sized for fitting into the detent pocket of the locking block member and is resiliently urged by a second resilient member disposed between a movable portion of the support arm and the engagement member such that the engagement member will be displaced into its engaged position in the detent pocket when the engagement member is aligned with the detent pocket and will be moved to its disengaged position when the support arm is moved to its disengaged position.
