"My 'invention relates to improvements in' golf clubs of the general class shown in my co-pend ing application SerialNo. 708,843,filied November 9, 1946, now abandoned. h

1 The objects of my invention are to provide improved means for varying the weight and balance of golf club heads by adding or Withdrawing a plurality of separate weightscwhich may be distributed, through the head in various spaced relations; to provide an improved detachable-top plate for golf clubs to permit convenient placing or replacing of such weights; to provide such a cover plate with means which will silence it, will secure it against displacement or slipping, and will facilitate the attachment or removal of same.

My invention is intended primarily for application to drivers and similar clubs having heads of aluminum or other light metal, but may be applied to clubs having heads of wood, plastic or other suitable material.

I attain the objects stated by the means illustrated in the accompanying drawings, in which;

Figure 1 is a top or plan view of my club with the top plate formed in circular form and provided with threads co-acting with corresponding threads formed in the sides of the recess or opening in the top of the club head;

Figure 2 is a cross-section on theline 2--2 of ure 1;

Figure 3 is a plan view of an alternate form of plate having its front edge formed at an angle to the bottom of the plate and its rear edge formed at a right angle to the bottom of the plate to facilitate attachment thereof and secure the plate firmly in place;

Figure 4 is a sectional view on the line 4-4 of Figure 3;

Figure 5 is a plan view of another form of plate with scalloped ends but with its edges formed at right angles to the bottom of the plate to facilitate insertion and a screw to secure the plate firmly to the head.

Figure 6 is a sectional view on line 6-6 of Figure 5.

Similar numerals refer to similar parts throughout the several views.

In Figure 1 I have shown the head I which may be united to thehandle 2 in any of the ordinary ways. Acircular plate 5 threaded around its periphery, is seated in a suitable circular socket or recess formed in the top of the head I with the threads of thecover plate 5 meshing with corresponding threads formed around the sides of the socket.

The top of the plate is provided with aslot 2 Claims. (01. 3 77) l l' by theuse of which a screwdriver or small coin may be used to tighten or remove the plate from the head. Formed integral with theplate 5 is a plug 5.1 which seats in a corresponding socket formed in the head I.

Thecover plate 5 may be formed of the same material as the head I or may be of either heavier or lighter material as desired and the plug 5.1 may be omitted.'

A plurality of vertical bores are formed in the head in which threaded cylindrical weights 9 and Ill may be inserted, the sides of the bores being threaded to correspond to the periphery of the weights. The top of each weight may be provided with aslot 8 adapted to receive a screwdriver by which the weights can be inserted or withdrawn.

The weights 9 and In may be of lead or any other desired metal and if desired, either the lower or the upper weight may be made of very light metal or of plastic so as to vary the height of the weights above the sole of the club if desired.

Likewise, theplate 5 may be formed of either metal or plastic.

In Figure 3 I have shown a diiferent arrangement of the bores and weights in with the form of the cover plate A changed to correspond.

In Figures 3 and 4 the cover plate It is shown with its front edge beveled or standing at an acute angle to the bottom of the plate and arranged to fit a corresponding groove in the recess formed in the head of the club to receive the plate, while the rear edge of the plate is substantially perpendicular to the bottom of the plate so as to permit facile introduction and removal of thecover plate 4.

In Figure 5 I have shown another arrangement of the weights Ill and the cover plate 6 formed with scalloped ends to more firmly secure the plate against lateral movement and prevent rattling. The cover plate may be additionally secured in place by a screw l extending downwardly into the head. In this case, the edges. of the cover plate are intended to be perpendicular to the bottom of the plate and to fit snugly in the recess of the top of the plate I' to receive same.

The same kind of weights 9 and I!) may be used for all three forms of cover plate.

In the operation of my club, the club may be turned out with all of the weights 9 and Ill in place and the user of the club may then try it out and adjust the weight of the head as seems best fitted to his particular needs. He can remove the cover plate and take out one or more of the weights and then replace the cover plate or he can remove one or more of the weights and replace them with weights of heavier material. If desired, the club may be furnished originally and tried out by the user without any weights and the user can then insert weights as desired.

It is obvious that when it is desired to increase the back spin of a ball, the lower weights 9 only may be used and the upper Weights Ill omitted and when it is desired to increase the overspin of the ball, the lower weights 9 may be omitted and the upper weights It alone inserted The form and arrangement of the parts, if

closely fitted, are designed to prevent any play' or slack and to avoid any rattling or noise which might be due to a loose plate or weight.

By the term driver type in the claims I refer to clubs having the form of wooden drivers,

brassies, spoons or lofters and not to irons such as iron driver, cleeks, or midirons.

Changes may be made in the size, proportions and forms of the parts without departing from the spirit of my invention and I do not limit my claims to the precise forms shown in the drawings.

I claim:

1. In a golf club of the driver type, a head having a plurality of vertical bores extending from the top of the head downwardly into the body thereof to a spaced distance from the sole of the club, a plurality of weights detachably seatable in said bores, and a detachable flat cover plate of sufiicient size to cover all of said bores and to seat closely in a recess formed in the top of the club head corresponding in shape to the cover plate.

2. In a golf club, a head of the driver type having a plurality of vertical bores extending downwardly from the top of the head into the body thereof, a plurality of small cylindrical weights threaded into said bores, a detachable cover plate of sufilcient size to. cover all of said bores removably seatable in a recess formed in the top of the club head corresponding to said cover plate, and means to retain the cover plate securely in said recess comprising an angular groove in the head at the front edge of the recess, and a bevel formed on the front edge of the cover plate adapted to enter said angular groove.
