The bushings 20 and 2| are provided with headed ends 20a and Zla respectively to provide shoulders for engaging the ends of the tubular blank I9 and also forming projecting anges for the ends of the leather winding I8 with which the handle of said bushings are lush.

The head 20a of the upper bushing 2l) is slightly domed to permit it to seat detachably in a cup-shaped socket 22 affixed to the lower open end of the upper tubular handle l2.

The lower bushing 2| is provided with a snapaction ball 23 having a slidable t in a cylindrical cage 24 located within said bushing 2 I, said ball being prevented from dropping out of said cage by an inwardly extending. annular rim embracing said ball at a line slightly below the center thereof, thus securely holding it in posi'- tion and at the same time permitting the ball.

to protrude downwardly slightly.

The ball 23 is adapted, normally, to seat in a concave' socket 25' formed in the headed, upper end 26 of a plug 2l iitted into the upper end of the' shaft l0. The plug 2:1 is supported and securedzin. the upper end'ofsaidshaft ill by means of.` a; transverse rivet 28; which is located below the bottom ofl thehead 26. of said plug 2li, leavingl a space 2.9.* for a purpose to be hereinafter described.V

The stopmember'' is rotatably mounted upon the body of the plug 21,' andthe ring 39 is positionedin the space 2S" previously referred to (see The nger 4D extends upwardly a suflitachable section I3', and when said nger isy at right .anglesto the. plane of .the offset brace mem- 755er berl4 land'in itheplaneof-r the swing,. itwill eifec.-

tively prevent the displacement of the same by the impact with the ball. (See Fig. 4)

A resilient undulated washer 39a is preferably located between the ring 3S and the top edge of the tubular shaft i to prevent wear and maintain a uniform resistance to turning of said stop member 38 (see Figs. 2 and '7).

Operation In the use of the improved practice golf club, herein disclosed, when it is desired to make a practice swing without striking at a golf ball, the player will' iirst twist the stop member 33 so that the nger lil will lie in the position at the underside ofthe club handle as shown in Figs. l and 3, in

the plane of the offset brace ili. The nger lil will then lie out of the path of the normal swing and will not interfere with the displacement of the indicator section i3 if a faulty stroke is made. If the swing of the club is properly controlled by the left hand to produce a smooth, even and rhythmical stroke, the club will remain intact through the entire swing. If; however, the pupil makes the swing in a jerky manner, or exerts too much force with his right hand, the detachable section i3 will become disengaged from the shaft iii and will thus indicate to the player that his swing has been faulty.

By reason of the snap engagement of the ball 23 with the socketed plug 2l, the detached section I3 may be readily replaced and the club will then be ready for another stroke.

When it is desired to use the practice club in the manner of a regular club for striking and driving a golf ball, the stop member 53 will be twisted about the shaft through an angle of Sil degrees until the linger #lil lies in the swinging plane of the club, as shown in Fig. Il, on the saine side of the shaft it as the striking face of the club head. With the stop member 33 in this position, it is quite obvious that it will be impossible for the lower gripping section i3 to become detached from the handle i2 by the shock of the club head in hitting the ball. It will thus be possible to use the club when so adjusted -for playing in the usual way.

In order to hold the detachable section i3 from being accidentally knocked out of position while the club is being carried in the golf bag, provision is made of a split resilient metal clip lil (see Fig. 6), having a pair of opposed curved arms 42 and i3 for slidably and detachably embracing the upper end of the shaft lil. The clip iii also has a pair of upstanding outwardly offset fingers lli and "i for cooperating with the stop ring 38 in preventing displacement of the lower end of the detachable section i3, as shown in Fig. 7 in operating position. When using the club, the clip lil may be readily slipped downwardly to the dotted line unobstructing position as shown in Fig. 7.

While the operation oi the club has been herein described for use by a right-handed player, it will be understood that the invention is equally useful for left-handed players, it being merely necessary to change the club head without changing the handle or gripping section.

While there has been disclosed in this specication one form in which the invention may be embodied, it is to be understood that this form shown for the purpose of illustration only, and that the invention is not to be limited to thespecinc disclosure but may be modiied and embodied in various other forms without departing from its spirit. In short, the invention includes all modiflcations and embodiments coming within the scope of the following claims.
