Abstract

See full text

The combination padlock of the present invention incorporates tumbler or clutch wheel constructions which cooperate with the rotating dials to virtually eliminate any possibility that an unauthorized person would be capable of gaining access to the padlock by known combination lock picking techniques by forming each tumbler or clutch wheel with a plurality of radially extending fins formed thereon, with each of the fins being arcuately spaced from the adjacent fin in a non-symmetrical pattern. Furthermore, the padlock of the present invention incorporates a unique combination setting and re-setting assembly which employs a slider shaft incorporating a radially extending post, which must pass through a key-hold slot formed in the body or housing of the padlock for activating the combination setting or re-setting mode, and cooperates with a set screw member threadedly engaged with the housing or body of the padlock which controls the axial movement of the shaft.
