  • Patent number: 5028051
    Abstract: A putting practice device (10) that may be used indoors or outdoors to improve a golfers putting. The device (10) consists of a putting surface (14) having therein a golf cup (16), a first golf ball (20) pivotally mounted adjacent one edge of the cup, a lever (30) coupled to the first golf ball (20) to facilitate movement of the first golf ball out of the cup (16), a second golf ball (40) positioned adjacent the opposite edge of the cup (16) from the first golf ball (20), and indicia showing desired movement of a golf club during a proper putting stroke. When the first ball (20) is struck, it pivotally falls into the cup (16) and the "follow through" will then strike the second ball (40). If the "follow through" is correct the second ball will continue in a straight path; if not, the ball (40) will go to one side or the other indicating a correctable problem.
