Abstract

A device for preventing unauthorized access to a rotating shaft. More particularly, an apparatus is provided to prevent unintended and unauthorized operation of a rotating shaft by encasing a vulnerable portion of the shaft in a standard pin type lock which renders the shaft impervious to unauthorized operation. It is intended that the rotating shaft cannot be operated unless it is unlocked and a tool is applied to a portion thereof.
