j Application Maria, 1946, Serial nastiest l 1 This invention relates to test, corrective, and teaching equipment, and particularly to such equipment to, be used in the playing of golf. QIt'is] well-known in thegame of golf that stance is'oneof the prime factors-bearing on the ability ofjagolf playert'o playthe game'well With minor exceptions, the position and swing of, a golf player determines the distance and accuracy ofthe iiight of the ball. One of the indications of the proper 'stance of agolf player is the position of his head, it being well-known that if the headshifts to too great an extent, either forward or backward, with respect to the direction of flight of the ball, or upwardly, during the stroke, either the club head will notproperly contact theball, or the desired amount of impact willpot begiveri to the ball.

The presentinvention is directed to a device which ,will permit freedom of movement of the body, armsiand club, while indicating anyundesirable extent of movement or shift of the head both along the line of flight of the ball and in a direction transverse to the direction of flight of the ball. Furthermore, if the movement of, the head is at an upward angle, such movement will also be indicated. The device provides permissible-movementwithin limits consistent with a good golf swing, but indicates any movement beyond these permissible limits. In general, the device consists of an electrical contact device which may be attached to the head of the golfer, and which will indicate to the golfer, or to an instructor, any movement and its direction beyond permissible limits. 1 s

The principal object of the invention, thereforefis to facilitate the teaching and learning of good golf playing.

Another object of the invention is to provide a device for indicating improper body movements during a'golf swing. H s s I A' furtherbbject of the invention is to provide an indicator of the movement of a golfer's head beyond permissible limits during a golf stroke.

A still further object of the invention is to provide an indicator of a golfers movements during thecourse of a golf swing. Y i l Although the novel features which are believed to be characteristic of this invention will be pointed out with particularity in the appended claims, the manner of its organization and the mode of its operation will be better understood by referring to the following description read in conjunction with the accompanying drawings, forming a part hereof, in which:

9 clai s.- (01.273-35) Fig. 1 is aperspective view of the device em bodying the invention in operation.

Fig. 2 is a cross-sectional view ofthe indicator of the inventiontaken along the line 22ofEig.i Land Fig. 3 is a schematic diagram of the electrical circuit of the invention.

Referring now to the drawings, inf which the samefnumbers identify like elements; abox or casing 5 with a cover fihouses the mechanism for indicating movements of a golfers head as indicated. A band Iisplaced around the golfers head and through a cord 8 is connected withfan armature element l0 protruding from an opening II in the sloping panel l2 of thecasing 5/ At I5, l6, and H, are indicator lights, while an opening may be'p'rovided at 20 for permitting sound to pass freely from the interior of thecasing' to theoutside. t f

Referring now to Figs. 2and 3, on the left side of the opening I! is a metallic electrodeilron the right side, a metallic electrode 22; and on the upper side, a metallic electrode23. The armature i0 is metallic, and may be pivoted or otherwise attachedto the back of the casingi As shown in the drawing, one end ofaspring 25 is wrapped around a mountin ost, 26 and the end of armature Ill. This type of mounting permits the armature ID to be rigid. Should a flexible armature be used, its end could be fixedly attached to the back of the case.' The lamps l5, l5, and Il may have'diiferently colored globes, such .as red, white, and green, while, in shunt thereto, are buzzers 21, 28, and 29 which are each tuned to generate a different tone. Itis realized, of course, that only two lights l5 and I6 may be used with'a buzzer 29 or other different com bihations, although to provide both aural and visual indications in all three directions, the triple indicatorsfjas illustrated, arepreferred.

' Any suitable source; of energy, such as a dry cell 3 I; is provided, together with a master switch 32, which maybe arrangedto be closed when the cover 6 is opened. The armature I0 is mounted so that in its rest position it isequidistant from electrodes 2!, 22,land 23. 23 may be adjusted closer to the armature l0 than electrodes 2| and 22, if desired, to indicate a less upward movement than horizontal movement of the head. With the switch 32 closed, it is realized that if the armature l0 makes contact with either of the electrodes 2|, 22, or 23, a circuit will be made and the respective lamps I5, l6, and I! with buzzers 21, 28, and 29 will be energized. If the armature I0 is moved to However, electrode
