ABSTRACT:
A pair of combination locks is employed to hold the lid of a luggage case cked closed, with a left-hand lock operating as a mirror image of a right-hand lock. Principal parts of the locks, including improved dial-indexing springs (but not the dials) are interchangeable. The dial-indexing springs cooperate with the dials of left-hand and right-hand locks in the same manner, so that all of the dials have the same action.
