Abstract
An electric gear motor with reduction gears and automatic brake for shutters, wherein an emergency control is provided to allow the shutter to be manually maneuvered in the event of motor brake down or loss of power. A toothed ring is normally retained in a non-rotatable position relative to the reduction gears under the influence of a yieldable leg of a spring pin. The yieldable leg is movable away from the ring to permit the ring to rotate with the reduction gears and free of a motor drive shaft in the event the motor fails to activate in a normal manner thus enabling the shutters to be manually operated.
