ABSTRACT:
A quick mount combination lock constructed to be readily installed or changed to assume any of the four right hand, left hand, vertical up, or vertical down installation positions from externally of the lock case, wherein the lock case includes a front case section and a rear cover plate providing a lock mechanism chamber housing the usual tumbler wheels, a drive spindle extending from a dial, and a drive cam adjustably positioned on the spindle by a spline key at any of four angular positions correlated to said installation positions. The front case section has an integral flange extension protruding from an end wall of the case having a mounting screw opening, and the front case section and cover plate have aligned mounting screw holes extending entirely therethrough whereby the mounting screws for the lock case are accessible for installation and withdrawal without removing the cover plate from the front case section. The cover plate has an access opening concentric with the spindle axis for removal and installation of the spline key releasably retaining the driving cam in any of the four angular positions on the spindle, and a removable closure button member for the access opening.
