GOLF CLUB Application tiled March 12, 1929. Serial No. 346,338.,

My invention relates to the class of devices above named,`and anobject of my invention,`

among others, is the production of a golf club by the use of w ich increased advantages may be obtained in the use of the club.

One form 'of club' embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attaine'd, is illustrated in the accompanying drawings, in which- Figure 1 is a view in elevation of my improved club, looking at the striking face of the head.

Figure 2 is a similar view but looking at the end of the head.

Figure 3 is a top view.

Figure. 4 is a view, scale enlarged, lof the head looking down, and vwith parts broken away to show construction.

In the accompanying drawings the .nuf meral 5 denotes the head of my improved golf club that may be of any desired material and generally of any vdesired shape, and provided with a striking face 6 in a manner common to devices of this class. A shank 7 extends from the head, a shaft 8 is secured to the shank and a handle 9 is located at the outer end of the shaft. All of the parts thus far described may be of any ordinary and wellknown construction. My invention comprises -a head for a golf club that is weighted and in which the weight is movably mounted, in the particular form of my invention herein illustrated and described, a recess 10 being made in the head preferably opening at the heel and closed by a cap 11. A lining or sheath 12 is made to t the opening or recess 10 and a ball cage 13 projects into the chamber within the sheath. 40 This cage has holes spaced apart to receive balls 14 that act as bearings for a weight 1.5 that is loosely mounted in the chamber, the balls facilitating ease of movement of the weight. In the structureT herein shown the '45 lining 12 is formed as an `integral part of a plate 16 placed on the back surface of the head, and as shown in Figurel of the drawings, this plate being located between the cover 11 and the main part of the head.

InA order to restrict movements of 'the' lance may be employed to suit the vfancy of or brassie type,

come. By mounting the weight 15 so that it Weight to a limited extent a spring 17 is placed at the end of the weight, 1n the-structure herein shown this spring being located in a cavity 18 in the cap 11. The cap is removably secured in place as by meansof screws 19, and this removability of the cap enables the spring to be readily changed so that springs with various degrees of resistthe player. 0|

kAccording to the accepted correct form for swinging a golf club of the driver, spoon the downward movement of the club should be executedV with the hands and club lagging slightly behind the wrists until the head of the'club almost reaches the ball when the saidhead is brought forwardly with a snap by a wrist movement which causes the club head to catch up with the wrists at the instant the ball is struck. Improper timing of this wrist movement or snap causes the ball whilein-iiight to deviate from its intended course in the form of a slicey or hook. The beginners game usually suii'ersy from a slice which is due to the lateness in timing in the above mentioned Wrist movement or snap causing the wrists to reach the ball in advance Aof the club head. Golf clubs ofthe above mentioned type now in common use usually have a iixed weight or Wei hts in the head and it is believed that if this dead or fixed iload could be removed or lessened during a part or all of the wrist movement the tendency toward late timing would be over- '86 may move relative to the club head in a direction rearwardly of the movement of the head or stated in a different way, if the weight is permitted to lag behind the head during the quick forwardsnap of the club head in executing the above mentioned wrist movement, it is believed that a material improvement'in |the timing ofthe swing will be ex erienced.

This snapping of the club head orwardly independently of the weight might be compared with the old magicians trick of snapping or jerking a tablecloth off of a full set table without upsetting any of the dishes or pulling any of them olf of the table with the cloth. It also is believed that the return 10 of the weight to the forward end of the recess, which is believed to occur approximately at the time the ball is struck, will tend to assure a perfect follow through of the swing. Unquestionably, the mounting of the weight 15 in the head 5 so as to permit the weight to move against the tension of the spring 17 will produce a yielding or resilient blow as distinguished from the dead blow produced by a club with a fixed weight in its ead.

The rapid swinging movement imparted to a golf club will set up centrifugal action tending to cause a movable weight to bind against the wall of the recess in which it is mounted unless some form of anti-friction bearing is provided. For this reason, the weight 15 is supported by the balls 14 and a free movement of the weight, restricted only by the spring 17 and the' closed end of the recess, is insured whereby either or both of the above mentioned beneficial results may be accomplished.

I claim- 1. A golf` club including a head having a chamber therein, a weight movably mounted in said chamber and free to make contact with the forward .end thereof, a plate placed against the back of said head, a ball cage integrally formed with said plate and projecting into said chamber, balls positioned in said cage, a cap to close the rear end of said chamber, and a spring located between said cap and said weight and exerting pressure upon the latter.

2. A golf club including a head having a chamber therein, a lining for said chamber, an anti-friction bearing unit including a cage portion carrying balls positioned within said lining and a plate portion connected to the cage portion arranged to lie against a surface of the head, a weight movably mounted within said cage portion and on said balls, a cap, having a chamber to register with the chamber of the head, secured to the head and overlying said plate portion, and a spring within the chamber of the cap to urge the weight tolvvarl the front end of the chamber 1n said 3. A golf club including a head having a i chamber therein, a lining for said chamber,

an anti-friction bearing unit including a cage portion carrying balls positioned within said lining and a ange connected to the cage portion and projecting laterally therefrom to retain said cage in position, a weight movably mounted within said cage portion and 'on said balls, a cap having a chamber to register with the chamber of the head and secured to the head, and a spring within the chamber of the cap to urge the weight toward the front end of the chamber in said head.
