Means connect the spindle to the bolt for moving the bolt between its positions upon rotation of the spindle. An operating assembly comprises a hand operator having locking means therein, a first plate mounted for linear movement in a direction transverse to the axis of the spindle. An actuating member is connected to the hand operator for moving the first plate. A second plate, has linear movement transverse to the axis of the spindle and is adapted to be moved by the first plate.
