GOLF CLUB HEAD WITH WEIGHT ADJUSTMENT Filed Jan. 24, 1955 United States Patentt()j .GOL'F CLUB 'HEAD WITH WEIGHT ADJUSTMENT Austin N. Clark, Winnetka, Ill. Application January 24,'1955,-Serial l\lo.4 483,598

7 Claims. Y(Cl. 273-171) 'I`This .invention pertains-'generally to golf clubs and -particularly to a new and improved;c.onstruction,for

wooden club headsembodyingtmeans for adjusting the weight and vbalance thereof.

' From early timesin thegameeofpgolf, it. has been the practice of clubmakers to` add orfsubtract weights to the headsof wooden f golf clubs to accommodate individual '.tastes and .playing habits of ,the users.

Generally the manufacturer attempts toproduce a standard .or normal .weight for the` particular'wood inquestiorrand usually provides individual weight adjustment by boring aV hole .orholes-in thehead and llling the same with lead plugs, etc. Therek are'serious objections to; this practice, chiefly `due to -the'diffculty and inconvenience of` adjusting the club weights'to meet individual. needs. Each set of clubs is usually factoryA customized. and the addition ofllead plugs'in theghead' ofthe .club is accomplished bytapping the plugs into bore holes. The ,tappedplugs have a ytendency tofworkiloose after a' time and become lost in use. Y

vThe present invention is intended primarily to presenta new and improved means foradding or subtracting `weights tothe head of a golf clubgparticularlythe wood clubs., Whichmakes it possible for the individual to .regulate the weight andbalance of hisgolfcl'ubs himself or to i havethem adjusted in his local pro-shop totmeet his own particular needs and desires. Means are provided in the Limproved, weight adjustment. Vsystem `of this 'invention topreventthe rattling or loss of weights andthe entire means is embodied in a; uniqueihousing `arrangement withinjthe club head which eliminatesany unsightliness or detraction .from the vfine workmanship normally atwoods` in sucha manner thateach player'may easily custom lit and-weighthis ownY golf clubs.

J The above` and Zfur'therfobjects, features and advantages of this invention will be apparent `to'thosefskilled inthe Aart:l from 'the followingfdetailed descriptionand fspecilication^ofzitsiembodirnentsrset forth inthe accompanying drawings.

Turning now to the Vdrawings -it willbe recognized best from Figures- 1 and 2 that a wooden golf club head `10 is fitted with the usual sole. plate. 11 which laysalong .the bottom face of the club head.,and` extends substantially' fromA a hitting or forward face. 12 thereof to its rearward face .or heel v13. A heel plate 14, suitably Ycontoured torneet the configuration of rear face 13 -is -tlittedand formed vfor reception in a recess formedin the rear' face 13.

TThe V.distinction-of ,this'inventiom however, is best illustrated inFigLlres. 3 -and 4 of the'drawingsinwhichthe heel plate 14,.-is...shown, as. cast forformed -integrally .with a tray .member 2.0.which is insertablein a'blind cutout,.or,hol .low,21 vof substantially..rectangular configuration `formed in the head member. 1t). fInl particular, Vthe'tray member l2ll. comprises an.upper wall: 22, a pair'of parallelside Twalls23l23 (seeA Figure 4) anda pair of end-Walls .24 and..25. lwhich --are respectively. .provided .with locating lugs 26 and.` 27. .It will be understood thatthe. several r.walls of ,the .tray member are interjoined and .preferably castor-'formed.integrally with the heel plate 14. VAj-pair ^of web wallsl,l 28 extend fromthev one end..wall.25.as ',continuationsofthe .side walls. 2310 join -the.heel.plate 14. .with the `tray;..such ,webwalls fbeing. substantially triangular in shapeasbest seenin Figure. 3. kThe forward endtwall.24,.inadditionto having. the lug 26; .is:also provided. with.. a .lip 30; projecting: in an. opposite .direction irom.lug,26. iThis.1ip has'aforwardedge which-issuitably `formedat anangle to forman .inclinedplane-or wedge face 31. This face 31 is received underneathV an .overhanging .inclined` Iportion of.. aV wedge` lug 32 which may.,be..cast integrallvwith. the sole plate- 11 :orfixed ,theretoas byf a rivet-member 33, asshowmor by welding or` othersuitable connectivemeans;

f- In Figure -3 fitwill.-beaseenfthat'fthelocating-lugs -and.f v27 ron 1' -.the- .twor end-f Iwall portions s; 24 fand .25=are designed especially to coaxially locate substantially square weight members 3S and a spring member 36. Particularly, one or more weights 35 may be employed and inserted in the interior of the tray member 20; such weights each being formed with an extending lug portion 37 and a hollow correspondingly located and designed to mate with the lug portion 37 of an adjacent weight so that the same may interlock with each other. The weight 35 placed adjacent the wall 24 will, of course, lock and locate coaxially with the extending locating lug 26 formed on such wall. A compression coil spring 36 is employed between the weights 35 and the second end wall 25; this spring locating itself on the lug 37 of the lirst weight and projection 27 of end wall 25. The spring, of course, serves to keep the weights in place and prevent their rattling. It will be recognized that variations in the Weight of the club head may be easily accomplished by the removal or addition of the individual weights 35 to fit the particular needs of the player.

In Figures 5, 6 and 7 I have illustrated a modified form of tray member 20a which features certain improvements as will now be described.

The head member 10 of Figure 5 is equipped with the modified tray member a as mentioned hereinabove. Such tray member is substantially the same as tray 20 heretofore described except that the end wall a thereof is equipped with an enlarged and elongated locating stud 27a which acts as a centering guide and keeper for one end of a conical coil spring 36a. It will also be seen from Figure 7 that the upper wall 22a is formed dome-like on its interior face which mates with the matchingly shaped weights 35a. In regard to spring 36a it will be noted that the same tapers endwise so that the coils at one end thereof are smaller than they are at the other end. This configuration for spring 36a has been found satisfactory and especially desirable in certain instances, as for example, that illustrated in Figure 6 wherein two of the four weights 35a shown in Figure 5 have been removed. Normally, spring 36a is disposed with the coils at its larger' end over projection 27a, as seen in Figure 5. With the removal of two of the weights it will be appreciated that the compression of spring 36a is considerably decreased. This being the case, reversal of the spring, as shown in Figure 6, allows the smaller end portion 40 thereof to remain spaced from the end wall of the tray when such is engaged with the enlarged conical stud or guide 27a. This effectively provides sufcient compression of the spring to accommodate the removal of the two weights. This function and feature is not possible with the cylindrical spring and construction illustrated in the device of Figures 3 and 4.

It will also be noted that in the construction set forth in Figures 5, 6 and 7, the locking lug 32a is formed integrally with the sole plate 11 as opposed to the riveted construction seen in Figure 3 and described in conjunction with tray 20.

From the above it will be understood that I have set forth the structural aspects of a new and improved adjustable weight system construction for the head of a wood golf club which permits ready and easy variation in the weight distribution and mass of the head to meet the desires and playing habits of individual players. Due to the extreme simplicity of the construction it is obvious that even the most amateurish mechanic may remove the holding screws 1S, so that either the tray element 20 or 20a, as the case may be, with attached back plate 14 may be removed from the interior of the club head and the desired number of weights removed or added as desired.

While I have illustrated and described the improvements as applied to two variations of the same basic invention, it is obvious that numerous other changes, modifications and substitutions of equivalent materials and constructions may be employed in carrying out the intentions and purposes of this invention, without neces- 4 sarily departing from its spirit and scope. As a consequence, it is not my intention that I be limited to the particular form and features of the device disclosed and described hereinabove except as may appear in the following appended claims.

I claim:

l. Means for regulating the weight of a golf club having a wooden head, comprising, a sole plate fastened to the underface of said head, a blind chamber opening inwardly from the rearward face of said head and extending toward the front face thereof, said sole plate closing over the bottom side of said chamber, a heel plate enclosing the open end of said chamber, a tray member connected at one end to said heel plate and inserted axially into said chamber, plural weight members carried in said tray member adjacent one end thereof, means removably interlocking said weight members, and spring means located between said weight members and the other end of said tray for resiliently biasing said Weights tightly against one another.
