Title: Improvements in and relating to golf practise apparatus
IPC: A63B71/06
Filed: 1938-06-02
Abstract: 504,164. Golf - - practising appliances. COHN, H. June 2, 1938, No. 16581. [Class 132 (ii)] A golf-practise apparatus comprises a ball tethered by a cord to a spring drum which, by displacing an intermediate member actuates a pointer over a scale of distances, and manually releasable means for locking the pointer in its registering position to permit the player to note the distance of the drive before restoring the pointer to zero. The apparatus is contained in a box a, Fig. 1, placed at a convenient distance from a net b provided with an aiming plate f. The ball c is connected by a short cord d to a cord e secured at one end to the floor at k and at the other end to a spring drum 13, Fig. 4. In passing to the spring drum the cord e is guided by a cord guide 8 secured, by an horizontal pivot pin, to a circular contact member 11 rotatable about a vertical axis. When the ball is driven into the net the cord e rotates the spring drum 13 and its shaft 16 against the resistance of the drum spring. The rotation of the shaft 16 traverses a nut 28 and rocks a lever 29 about a pivot 30. The end of the lever carries an upstanding rod 31 which actuates a rack and pinion gear to move a pointer over an arcshaped scale 10 of distances. On the return of the spring drum a coil.spring clutch 36 couples the drum shaft to a centrifugal speed governor 25 to control the return speed. The indicating pointer is retained in indicating position by a pawl until released by a handoperated knob 47. The cord e is guided on to the spring drum, whereupon a spring returns the pointer and its rack to normal position, by a spring-pressed flanged wheel 33. If the player pulls or slices his drive, the cord guide 8 is displaced horizontally and imparts a rotation to the contact member 11. The contact member 11 co-operates with contact arms arranged in circuit with five indicator lamps L, the circuits being arranged so that a straight drive (cord guide 8 in central position) illuminates the centre lamp, a slice or a pull illuminates one or other of the adjacent lamps, and a bad slice or pull illuminates both of the end lamps.
