  • Key and retainer device for a chuck
    Patent number: 5800102
    Abstract: The present invention uses a collar that fits over a nose and a locking cylinder of a chuck of the drilling machine. The collar has a cutout section to accommodate the chuck key including the key gear when it is engaged with the beveled gear of the locking cylinder. The collar has a first bore of a first diameter with is slightly larger than the outer diameter of the nose to provide a tight fit between the collar and the nose of the chuck. A fastener is used to attach the collar to the nose of the chuck. A second bore has a second diameter to fit over at least the beveled gear of the locking cylinder. The second diameter is large enough to provide a clearance so that the locking cylinder is free to rotate within the collar. Turning the chuck key about a key axis opens or closes the jaws of the chuck to grip or release a bit placed along a drill axis of the drilling machine.
