Applicationfiled January 25, 1928; semi no. 249,240.

This invention generally stated relates to an amusement and instructive device particularly adapted for the useof golfers.

The leading ob ect ofthe present invention is to provide a device of the character stated so arranged, constructed and connected that the golfer hitting the objective maydetermine whether the stroke in reality would have been a straight ball, a- -slice or a Y pull. i

The further object oft-he present invention is to provide mOVableVisu-al means for determining whether the objective has been hit to produce a slice or the pull,

Other and further objects of the present invention reside in the provision of general details of construction, arrangement and combination of parts for attaining the resuits-sought by the foregoing objects.

The invention consistsof the device hereinafterdescribcd and finally claimed.

The nature, characteristic features and scope of the invention will be more fully understood from. the following description drawings forming part hereof, and in which Figure 1 isa view in plan-With certain Figure-4 is a view in longitudinal sectioir taken upon line l t of Figure l. V

Figure 5 is aview in cross section takenupon the line 5- 5 of Figure 1 Figure 6' a vieivin cross section, taken upon'the line 66 ofFigure 1'.

drawings one formthereof which is at pres ent preferred by me, since the. same has been found in practice to give satisfactory (and reliable, results, although it"is to be understood that the various instrumentalf ities of which my invention consists can be variously arranged and, organized and'that my invention is'not' limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

i the spring taken in COllllQC-lZlOIl with the accompanying" F igure 2 is a bottom plan View of Figure For the purpose ofillustratingtmy;inven tion I have shown in the accompanying; 7

By t-hisfarrangement and construction of Referring to the drawings in detail the reference numeral 1 designates a base plate usually ofumetal. and which maybe nalled or spiked to anyfappropriate surface as the ground or the floor in which connectionfthe:v

slots '2 are convenient for this purpose. The base 11s provided with an incline 3 best seen in Figures 1 and 4:. This incline 3' is used to guide the head of the golf club toward the. objective i, the latter preferably comprising solid piece of rubber, and in practice represents a golf ball. This objecv tive 4 is pivoted as at 5. to a frame 6'- probably best:- seen in Figures 1 and 9, although it is shown in dotted lines in. Figure=2i The object dis connected by means of a coil spring 7 as at 8 with the under side of the-incline 3 as is clearly shown in Figure t; j

Thus, as the objective is hit the top or upper portion thereof is deflected forwardly against the; springi', and; after the club head has hit the objective and: passes thereover- Tretra ctsthe objective at. This is true whether the objective is hit squarely or is-hit a glancing blow either to the left or the right, Theforwardend of'the frame 6' is provided with aprojection 9 which is adapted to move toward the left and the" right beneath-a plate =10 fixed to thebase 1 w This movement is;possibl'ebecause of" the pivotal or swinging relation-Jae at 11 of the. framefi with the base 1. The frame 6 connected atopposed sides with} the coil springs 12 and 13 respectively which are tact with, direction indicators designated 3100 16 and 17 respectively. These indicators 16 and 17-respectively are pivoted as at 18- to the casing l0 andare springpressedi as at 19.

parts if the objective i iS struck a glancing blow,.wh1ch in a game of golf would amount toapull the projection 9 contacts w th the pivotal'indicator 16 moves the same about" its pivotal point so that the signal 22 which may be for, instance. the color red is: moved before the openihgQO in plate 10. Onthe lio other hand, if the golfer hits the objective 4: a glancing blow, which in golf practice would amount to a slice, the signal 21; which might be black is moved before the opening 20 in plate 10, see Figure 6. r 7

Thus, the golfer by the manner in which said objective l is hit may determine whether the objective was hit to produce a straight ball, pull or a slicejthe advantages of which are apparent.

It is sometimes desirable that the base be not rigidly fixed but be mounted to take care of rebounds.v For this purpose the base may be provided with slotted ears 2?) at each end of the base, these ears in turn may be provided with coil springs 2st attached to ropes 25, the ropes in turn being secured to any desired fixture. The bottom of the base may be provided with

cover plates

26 and 27 in order to protect coil springs.

Among the advantages claimed for the above described device mention may be made of the following:

The indicator will positively disclose the manner of club swing. It will indicate if you are hitting the center of the objective (ball) or on the right or left of it. Any blow off the center of the objective will send the latter off on a tangent, that is, when the indicator will wink at you. The indicator will enable the user to obtain the proper stance, that is the distance to stand from the ball, position of feet in relation to ball, which is important in regard to hitting the ball fair. It will indicate if you are holding your club face'properly in relation to ball. It will show you, in swinging your club, if you crab your club at the wrist or shoulder, which meansyou are going to hit the ball with the heel or toe of your club. Above all, it will give you confidence in yourself and make you act natural. In other words, it will make you feel that you can put them where you want them, and also gives you exercise you cannot obtain upon other golf devices on the market. The device can be used anywhere there is room to swing a club.

lV hat I claim is:

l. A device of the character stated comprising a base, a swiveled member upon said base, an objective pivoted to said member, a central spring of relatively strong tension for maintaining said objective in neutral position, a spring of lesser tension upon each side of the objective spring and secured to said member to permit pivotal movement in two directions only, and means indicative of swivel movement of said member.

2. A device of the character stated comprising a base, a swiveled member upon said base, an objective pivoted to said member, a central spring of relatively strong tension for maintaining said objective in neutral an objective pivoted to said member, a cen tral spring of relatively strong tension for maintaining said objective in neutral position, a spring of lesser tension upon each side of the objective spring and secured to said member to permit pivotal movement in two directions only, and means indicative of swivel movement of said member.

4. A device of the character stated comprising a base, a swiveled member upon said base, an objective of solid rubber pivoted to said member, a central spring of relatively strong tension for maintaining said objective in neutral position, a spring of lesser tension upon each side of the objective spring and secured to said member to permit pivotal movement in two directions only, and means indicative of swivel movement of said member.

5.
