  • Patent number: 4165879
    Abstract: This invention relates to a parlor game for simulating the sport of golf. The game includes an elongated handle for being grasped and swung by the player. A flexible line is frictionally coupled through an aperture in the handle for providing a centrifugal force indication representative of a forward distance as the player swings the handle. A direction indicator is provided for being struck by the handle, or the player's hands coupled thereto, during the swing for providing a direction indication. A game board is provided which represents a golf course including a tee-off point and a hole point. Markers are provided for representing the position of each player as the hole is played. A converter adapts the indication from the forward distance and the forward direction indicators to provide a distance vector for directing the movement of the markers generally according to the rules of the game of golf.

  • Patent number: 4155191
    Abstract: A fishing lure apparatus for plug or spin casting has an elongated body having a swivel shank on the front for attaching a fishing line and a spring clasp on the rear for attaching interchangeable tail portions. The elongated body has a hollowed-out belly having a slidable mass therein which in one position maintains the lure with air entrapped in the hollowed-out portion, so that the lure floats on the surface and in a second position, tilts the lure to let the air escape so that the lure dives. An adjustable wobble plate or lip helps control the depth of the dive and the wobble of the lure. A sliding belly cover to cover a portion of the opening to the hollow belly portion may be used to provide additional weight and better air entrapment.
