Abstract

Abstract A savings bank having a combination operated lock. A frame is received within a casing and defines therewith compartments for coins and for currency. A combination dial on the casing rotates one or both of a pair of spaced, parallel discs in the casing, each disc having a peripheral notch therein. In the locked condition of the combination lock mechanism a leaf spring is biased by one or both of the discs into the path of a peg on the frame and prevents withdrawal of the frame from the casing. In the unlocked condition the notches in the discs are aligned with each other and with the head of the spring to permit the spring to retract out of the path of the peg on the frame.
