Patent GB-299224-A (GB)
Title: Improvements in and relating to golf practising appliances
IPC: A63B69/00
Filed: 1927-12-19
Abstract: 299,224. Backus, J. C. Dec. 19, 1927. Golf-practising appliances.-Relates to a golf-practising appliance of the kind in which a ball is connected by a flexible member to one end of a spring- retained plunger working in a dashpot cylinder, the plunger moving under the action of the momentum of the ball to indicate the distance of the stroke upon a scale and being automatically retained in its position of maximum displacement by a gripping device, whilst the deviation of the stroke is indicated upon a further scale upon the displacement of the plunger to a predetermined extent. According to the invention the flexible member connecting the ball to the plunger is adapted to operate a separate deviation indicating means. The ball 55 is tethered to a cable 36 which passes through an horizontal slot 12, Fig. 3, in the front of the casing, through an eye 47 in a lever 8, round a pulley 44 and thence to the spring-retained plunger rod 27 of a piston 28 slidable in a dash-pot cylinder 25. When the ball is driven from a tee 22, Fig. 1, or from a mat 21 secured to the top of the casing, the cable pulls back the plunger rod, and the plunger rod is prevented from returning by a locking roller 75, Fig. 4, which wedges between the plunger rod and an inclined bracket 70 secured to the casing. A pointer 43 carried by the plunger rod projects through the top of the casing and indicates upon a graduated scale 16 the distance of the drive. If the ball is sliced or pulled, the cable rocks the lever 48, Fig. 3, about its pivot 49 in one direction or the other, thus actuating a rod 69 and a lever 65 pivoted on a pin 66. The lever 65 carries a pointer 68 which projects through the top of the casing and indicates upon a scale 19 the extent of the slice or pull. To prevent the pointer 68 returning, a spring-pressed lever 77, normally held in the inoperative position by a pin 40 on the plunger rod 27, is liberated by the rearward movement of the plunger rod and clamps the toothed end of the pointer-carrying lever 65. Two spring-pressed levers 84 engaging the lever 65 tend to return the pointer to its mid-position. In order to effect the return of both pointers, a handle 95 is depressed, thus causing a cranked portion 94 of the handle-shaft to press back a U-shaped lever 71, Figs. 3 and 4, which at the same time carries back the locking roller 75 and liberates the spring-pressed plunger rod 27. The plunger rod together with its pointer 43 then returns to its zero position and the pin 40 removes the lever 77 from clamping relation with the lever 65 whereupon the spring-pressed levers 84 restore the pointer 68 to its zero position. The ball is tethered to the cable by means of a split pin 54, Fig. 7, having its ends turned over within a recess 55. A sleeve 58 is clamped on the cable and a shackle 61 has a rotative engagement with the sleeve about the axis of the cable. A link 57 connects the split pin 54 to the shackle.
