ABSTRACT:
An axial type, tubular key operated, cylinder lock which utilizes a plurality of spring-biased pin arrangements which are to be movable when connected with the proper key to a shear-line position achieving operation of said lock. A pin arrangement is movable longitudinally to the shear-line position. Any attempt to move a pin arrangement other than with a properly coded key will result in the pin arrangement being laterally deflected to a displaced-fixed position preventing operation of the lock.
