4 Claims. (273185) This invention relates to a golf practicing device and therefore is in a sense a game which serves not only to enable the user to perfect his golf stroke but to also ob tain exercise and pleasure from the use of the device.

In its broadest sense the device provides a captive ball, which is a simulated golf ball, which is stuck by a golf club in the hands of a user and as to whether or not the golf stroke has resulted in a sliced or hooked drive can be determined visually from the direction of rotation of the ball.

A captive type ball practicing device is not broadly new but such devices as are known and in use suspend a golf ball by a cord or cable and in either instance the suspending means for the ball is fully flexible. Such devices have been found to be unsafe because it has been found if the ball has not been struck fairly by the head of the golf club, as for instance if the ball is topped, the cord or cable suspending the ball will wrap around the club head and can-result in either breaking the club shaft or pulling the club head from the shaft. The ball suspending means of some known devices of the present sort are in the form of a metal rod or cable and with them if the ball is ftopped the club head will strike the rod or cable which; will result in the club head being nicked or marred.

An object of the invention is the provision of a device of the character described which is safe in that the disadvantages above referred to in prior devices are eliminated.

Another object of the invention is the provision of means topermit the simulated ball to rotate freely in either direction, that is clockwise or anti-clockwise, in accordance with the spin imparted to the ball by the manner in which it is struck by the club head to thus permit easy visual determination of whether the ball has been struck in a manner which would result in a slice or hook.

A further object of the invention is the provision of a device of the character described which is comparatively simple of construction, rugged to provide durability, effident in providing practice and determination of theerror in a golf swing, and comparatively low in cost of production.

Another and further object of the invention is the provision of a device of the character described which can be utilized in a comparatively small space or area and which, by slight modification, can be used either indoors or outdoors.

Another and still further object of the invention is the provision of a device of the character described which is portable and which can be quickly and easily assembled and disassembled to permit ready packaging or for storage in a minimum of space.

Other objects and novel features of construction, as well as advantages of the invention, will appear from the following description when read in the light of the accompanying drawings.

In the drawings:

Fig. 1 is a view in side elevation of the improved device.

\ tion of a further modified form of the invention.

Fig. 7 is a horizontal sectional view on the line 7--7 of Fig. 6, looking in the direction indicated by arrows;

Fig. 2 is a vertical sectional view on the line 2-2 of, Fig. I.

Fig. 3 is a perspective view, partially in vertical section, of the ball and the support therefor, the view being at right angles to Fig. 1.

Fig. 4 is a side elevational view of a modified form of the invention.

Fig. 5 is a vertical sectional view on the line 5-5 of Fig. 4. v

Fig. 6 is a side elevational view, partly in vertical sec-' Having reference now to the drawings which illustrate an embodiment of the inventive concept, and utilizing like reference numerals and characters to designate simi-' lar parts, A is a standard or support which is intended to' extend vertically above the ground 1 by having its pointed end 2 forced into the ground. To facilitate the securement of the standard in the ground it is, adjacent its lower end, provided with a foot tread 3 by means of which the pointed end of the standard can be quickly and conveniently forced the required depth .into the ground.

A horizontally disposed arm B has one end 4 rotatablywhich also permits rapid and easy positioning of the arm' on and the removal of the arm from the standard.

A plastic upper strap C has its upper end suitably se cured as at 6 to the opposite and free end 7 of the arm B. The lower end of this strap carries a spinner 8 to which is suitably secured-a second and lower plastic strap 'D. Formed as a part of this strap and at the lower end thereof is a simulated golf ball 9; The lengths of the straps C and D are such as to suspend the ball 9 the proper dis tance above the ground 1 so that it can be struck by the head of a golf club.

The spinner 8 permits the lower strap D and the simulated ball to rotate freely in respect to the upper strap C. When the device is in use the parts will be positioned as illustrated in Fig. 1. Upon being struck by a club head the simulated ball 9 and its carrying strap D will rotate clockwise should the golf stroke be such that a slice would result, and will rotate anti-clockwise should the ball be so struck that a hook would result. The direction of rotation of the simulated ball and its strap can be readily visually determined but visual determination of the direction of spin could be made more pronounced by coloring the ball by making half of it one color and half another color as is illustrated in Fig. 2 of the drawings wherein the half of the ball designated It) could be white and the other half 11 could be red in color.

In accordance with and response to the degree of force withwhich the ball is struck the horizontal arm B will rotate about the supporting standard A.

The spinner 8 need be of no particular or specific construction in that it merely embodies a roller raceway. In Fig. l the roller balls or rollers are designated by dotted lines at 12. It is only necessary that this raceway permit the lower strap D and the simulated ball 9 to rotate freely.

The horizontally disposed and rotating supporting arm B is supported on the upper end of the standard of upright A by a flange 13 or the like.

The straps C and D are made of some suitable soft pliable plastic and the ball 9, which is a part of the lower strap D, is of the same size as a regulation golf ball but would be lighter in weight than a normal ball. It has been pointed out that the means of suspension of the golf ball in devices heretofore known and used is unsatisfactory and dangerous because a fully flexible cord tends to wrap around the club head or shaft if the ball is improperly struck. With the present straps although they yield they are not sufiiciently flexible to wrap around a club head or club shaft and this is of tremendous importance as a safety feature. In Fig. 3 of the drawings the ball is shown partly in cross section as at 14 to indicate that it is plastic in nature. In this figure of the drawing the edges of the straps C and D are shown, whereas in Fig. 1 of the drawings the faces of the strap are shown from which it can be clearly seen that the ball suspension is of a strap form and is not cord-like as might be erroneously assumed from Fig. 3.

A slightly modified form of the invention is illustrated in Fig. 4 where similar parts are given the same reference numerals which they carry in the Fig. 1 construction. The main difference in this form of the invention resides in the supporting means for the simulated ball.

In this figure of the drawings the upper strap E is some- (I what shorter than the upper strap C and carries at its lower end an element 15 having on its lower end a raceway 16 to which is threadedly attached a cap 17 in which is secured the head 18 of a soft pliable plastic rod 19 the lower end of which is formed into a ball 20 which is a simulation, as to size, of a regulation golf ball. This rod is not to be confused with a flexible rope or string as it, like the straps C and D, is such that it does not have sufiicient flexibility to wrap around the shaft or head of a golf ball. With this construction a new rod and ball can be substituted for the old one should the occasion arise to make this necessary.

In operation this form of the invention is similar to the first described form in that the ball and rod are freely rotatable so that it can be visually determined from the direction of spin of the ball whether the practice stroke has imparted a slice or hook to the ball. To make this more easily ascertainable half of the ball may be colored diiferently from the other half as for instance one half white as at 21 and the other half red as at 22.

A slight further modification of the invention is illustrated in Figs. 6 and 7. Some persons using the device can accelerate the club head with sufiicient speed to make it desirable to take up the impact of the force exerted upon the ball.

Accordingly in this form of the invention the lower end of the upper strap E is provided with a housing 23 into which extends a short shaft 24 having a head 25 above a coil spring 26 in the housing 23., This shaft extends upwardly from a roller raceway designated as an entirety by F. A pair of spring arms 27 and 2S depend from the raceway and intermediate their lengths are outwardly crimped as at 29 and 39 to receive between them the pliable plastic rod 19 with the head 18 of the rod above the spring arms, as clearly appears in Fig. 6 of the drawmgs.

By this construction the rod and ball 20 are safely detachably secured to the raceway which will permit replacement of a used rod and ball should replacement be necessary.

Departures from the specific constructions illustrated and described can be made without departing from the 4 inventive concept, and the invention is accordingly to be limited only by the scope of the hereinafter following claims.
