Abstract
A combination locking device is disclosed. The device includes a spindle which is axially movable, has recesses in it and locking protrusion on it. Around the spindle are annular dials with markers on the outside and associated recesses on the inside. Between each dial and the spindle are gate wheels which have apertures extending radially from the spindle to the dial. The gate wheels also have recesses matching the locking protrusions and when the protrusions and recesses are aligned and the spindle moved axially the gate wheels are rotatably fixed to the spindle. A plurality of locking balls is located within the apertures. Axial movement of the spindle selects device conditions including a code change condition where the locking balls are able to enter the spindle recesses freeing them from the dial recesses and allowing the dials to move around the gate wheels.
