Abstract
A cabinet drawer interlock to prevent more than one drawer from being opened at one time has an actuator on each drawer which is engaged with a separate sprocket rotor. A number of locking bars arranged in end contacting relation and each bar having a slot. First and second pawls on each rotor are inserted between the ends of a pair of adjacent locking bars and within a locking bar, respectively, when a first drawer is opened rotating the rotor for that drawer. The remaining closed drawers cannot be opened since the associated locking bars contact the pawl ends on attempted rotor rotation.
