  • Patent number: 4423873
    Abstract: A golf club arrangement provided with indicia means to aid in the reading of the break of a green. The shaft of the golf club has a slot extending in the longitudinal direction which is either left open or filled with a distortion free transparent filler having parallel planar surfaces on opposite sides of the shaft. A square tubular shaft allows a maximization of the width of the slot to aid in the use of the indicia means. A cross hair intersects the indicia means at right angles to facilitate the positioning of the club. When the green is observed through the slot and compared to the indicia means, both the break in the green due to the natural lie of the grass and the overall slope of the green may be determined.

  • Patent number: 4327916
    Abstract: A golf club arrangement provided with means for "reading" the green. The shaft of the golf club is provided with at least a transparent portion extending in the longitudinal direction thereof. The transparent portion has an indicia such as an opaque line extending along the longitudinal direction and may be either on the surface or internal the transparent portion of the shaft. When the club is held vertically and the green observed through the transparent portion the natural lie of the grass can be more easily seen by reference to the angle made by the grass with the indicia.

  • Patent number: 3939034
    Abstract: There is provided a tab tape splicing apparatus for automatically fastening a tab tape on the adhesive surface of a rolled pressure-sensitive adhesive sheet at the end of the roll to provide a rolled pressure-sensitive adhesive tape with a tab at the leading end thereof. The apparatus comprises a rail fixedly mounted between a pair of upright frame members on both sides of a base to extend in the breadthwise direction of a pressure-sensitive adhesive sheet, a movable frame movable from side to side along the rail, a splicing roll attached to the movable frame for fastening a tab tape, a tape holder for holding a roll of tab tape, cutting means for cutting the tab tape, and means for moving the movable frame from side to side.
