  • Patent number: 3997169
    Abstract: This invention relates to a plastic, scoop-like device which easily, and without the use of tools, attaches to a golfclub iron, for the purpose of retrieving golf balls, or the like, from water hazards or other relatively inaccessible locations, or to pick up golf balls after a practice session. This device has two sides, bottom, and open ends, which is formed by bending a flat sheet of relatively thin plastic, permanently secured at its center top edge, which will cause it to resemble a "tear-drop" shape in its cross-section from that point of securement to one end of the device. From that same point of securement to the other end of the device, the cross-sectional shape fairs from the "tear-drop" shape to a form resembling a "U" in cross-section. The latter end of the device receives the "scooped" ball and the former end receives and attaches to the club head.
