  • Magnetic tool holder
    Patent number: 5213240
    Abstract: An improved magnetic tool holder for tape measures is provided in which a spoked keeper plate is mounted on the tool to be held in the tool holder. This results in a uniform holding force around the circumference of the holder so that the tool can be securely held in the receptacle and can be readily and easily removed by application of a controlled force. The holding force can be varied by varying the number of spokes and the width of the spokes. A self-centering ring and receptacle is provided to produce an audible click when the tool is properly seated with the keeper plate in intimate contact with the magnet and pole piece.
