ABSTRACT:
In the present changeable combination padlock the blocking lever which at one end is pivotally associated with the clutch elements for the dialing wheels and at its other end with the shackle locking bolts, is uniquely non-detachably pivotally mounted, intermediate its ends, on an inner, rigidly mounted angular supporting plate; and a pair of coiled springs equally spaced from the side margins of the blocking lever react against the underside of the blocking lever to pull it, with evenly distributed force from its locking bolt-releasing position to its normal position. Additionally, projecting exteriorally of a portion of the padlock case is a turnable changer button which, when turned ninety degrees by an applied tool, coin or finger nail is effective to release certain shaft-carried clutch elements from the permutation wheels for combination changing purposes when the shackle is unlocked and projected to its open position.
