Patent ID: 8893435

Claim:
A movable barrier operator comprising: a motor having a central longitudinal axis defined along an output drive shaft, the output drive shaft comprising a first end disposed on a first side of the motor and a second end disposed opposite to the first end on a second side of the motor opposite the first side of the motor, the motor further having a longitudinal length extending between the first side and the second side of the motor; a hand-operated chain hoist connected to the second end of the output drive shaft; a reduction mechanism having a longitudinal length extending between opposing sides thereof, the reduction mechanism further having a central longitudinal axis defined along a movable barrier drive shaft of the reduction mechanism, the central longitudinal axis of the reduction mechanism configured to be disposed substantially parallel to and lateral of the central longitudinal axis of the motor, the longitudinal length of the reduction mechanism further being configured to at least partially overlap and be disposed lateral to the longitudinal length of the motor, the reduction mechanism further comprising an input drive shaft; a transmission disposed to couple the first end of the output drive shaft of the motor to the input drive shaft of the reduction mechanism.
