  • Patent number: 4567685
    Abstract: A combination top water and under water fishing lure resembling a frog is described. The lure has a buoyant body portion moveably joined to a weighted hind leg portion which simulates a live frog at rest. The body portion is weighted at its posterior end whereby the anterior end or head end is maintained at an upright position in the water. A plastic dive plate attached to the anterior end of the body portion provides realistic kicking and diving action together with erratic head movement of the simulated frog being retrieved beneath the water's surface. The invention simulates the natural appearance of a frog in both swimming and at-rest modes.

  • Patent number: 4414772
    Abstract: A top water fishing lure having a keeled and buoyant head expressly designed to represent a snake or lizard, and which buoyant head is adapted to receive at the posterior end thereof commercial dressings such as plastic grubs, pork rind and plastic skirts. The invention may be selectively weighted whereby, on retrieval, the lure assumes any desired angle between 10.degree. and 45.degree. to the horizontal and which thereby, from the combination of factors of said angle, the surface appearance and shape of the buoyant head, and the motion of the posterior commercial dressing, simulates the natural swimming movement and appearance of a live snake, lizard, eel, frog or minnow.
