  • Patent number: 6802278
    Abstract: A device for inserting a utility marker is described that includes an elongated handle with upper and lower ends; a marker extractor adjacent the handle lower end that is moveable along a vertical pathway, and a marker magazine adjacent the handle lower end adapted to hold a plurality of markers including a leading marker adjacent the marker extractor pathway. The extractor, when moved to its extended position by pushing on the plunger, extracts the leading marker from the marker magazine, and inserts the lower end of the marker into the ground. Simultaneously, a valve actuator at the lower end of the handle is moved to an operative position to open the valve of an aerosol can, spraying paint adjacent to the marker. In one embodiment of the invention, the magazine is adapted to enclose a continuous roll of markers. In another embodiment, a housing adjacent the marker extractor pathway receives a replaceable magazine of stacked markers.
