App-imanes sie@ Deeemer s; i927. sei-isi ii'aesa/jfief 1f This invention relatesl to golf club icon! struction and has speeal reference to alock ing ineans 'for seouringinserts in*- 'the'strillringjft face ot'the head of a gell eluh: v

More particularlyj this invention relatesto a locking 'ineens for securing ank insert or a group ot inserts in the striking- 'aceofl agoli@ olubfin such a manner as Will obviateithe dit-r liculties due to the shrinking or enpandiiigof the bodyportion of the club'head Whichinter" tores with the eieiencyof the golf eluhto sev cure the'proper impact upon 'the ball when struckto'insure long 'distance flight and other desirable qualities sought 'in a golfr club.

Ordinarily inserts have beenr` threadedjor threaded and glued Within the golf club head whereupon ani rexpriding "of the golf club head Will permit tlieinsert to become loos@ enedwhieh will interfere inaterially` with the fliglitof'the ball. Furtherrsuch expansion of thejgol' club headv will leave playaround theiinsert and will Cause a splitting of the iii-f' sert;particularly acrosstlie portion Where the threads coininence duek to the iinpact rc, Ceived When striking the balli. Againglue subject to cliinatio conditions and`will not` perform thedesired functions unless these conditions are desirable.

inthe present construction, yit is `desiial'ile" to use'inserts which are sin'ooth and at! least one oi' which is et nietal, they be'ng so con structed and arranged as to nii Aiinizetlre engendered by they alterable quali# hazards ties of the material of ltlie head.` li/ioreover, these inserts are so heldin positionw'ithin the golf club head as to prevent the saine troni inovingI forwardl.)`7 or rearwardly or beconi inge; loosened in any'in'annei. This is acooinplished by' ineans oillo'clring'i the securing* ineans Within the 'golf elubheadibyn` secondary ineen s such asa sole plato, it'heii further desirable that the soleplateand have` no inte connecting i ine'ansp' One of the'objects of thisinveiitioinis' to" provide` an "improved means' 'for positively connecting the insert or insertswitli the inaliny body ot the cluh head so as to", prevent the lat?- ter roin'inoving forwardly or rearwardl or becoming displaced bythe shrinkingor pending el' the club' head proper..

Another Aobject of this invention is to pio vide ineans'ior locking` the securing; nieans of the insert "in the club head Wherehy` the insorts `will reinain tightly seated'therein.

the insert A `further 'obj ect this inten tionis 2to provide aplurality of insertsfor the 'headofa golf elub Wlierebyone of 'the inserts.` being seou'rely'held in the bodv y l y n head', holds the i'en'iainin tive relation therewith. A stili further object(1 F this invention isto provide a golf club'construetionwhich is 'durable, Whiehjinay. be.' readily assemble-:l and` which is pleasing in appearanoe. 1

Further objectsand advantages of this iiipoi'tion of the club grinsertsin a posivention will be apparent from the description" and drawings forming' a part of this speciiig" catioiito which lat-ter reference inai7 noui be i had foi aniore complete understanding,of the `charac'teristio features "of this ii'iifenti'on,A in' which drawings;

aportion thereof in section; and n K Fig. 46 is a central sectional View taken ony lpartieularly to'FigS. l, Zand `3 thereof, a golf other suitablev material having a face plate ll inlaid in the striking facel thereof.l The face plate l1 is preierablyof liberghard rub-y ber or other suitably ytough material [for the rSi? reason thatthe-(Wearing.propertiesthereof are i. inorede'sirable tlian'that of Wood and iortlie furtherA reasonthat K' Athe grain of thewood ormingthe golfclub head ordinarilyextends *j e `parallel Withthe striking;- falce 12'.'v A

club head and is disposed substantially eenv trallyof the Width thereof.y A counteifbored o,

socket 14 is provided. atthe lowerend of the ygolf clubto receivethe iinpaot iiisert'iir'snug r engagement therewith, the lar^er outer `portion of the `counterbored socket extending a substantial distance through the` ica-oe'plate ll, the smaller or inner portionof the socket extending' through thereinaining portion'of the face plate and into the body portion of the club head. The socket has preferably semi-circular contour and the impact insert 13 is shaped so as to conform to the socket, the loiver edge of the latter being' substantiallyflat to extend flush with the lower sui'- face of the club head. The outer end of the head 15 of the impact insert has a substaiif tially flat su `ce and is preferably flush with tlie striking race 12 and the face plate 11, the latter elements being` inclined rearwardly frointhe bottom of the golf club as is usual in golf club construction. Y

The impact insert 13 is held in a positive fixed relation With the golf club heat by means of a screw 1G extending from the flat lower side of the latter through the shank or smaller portion of the insert to be secui'ed to the body portion ofthe club head. The screw 1G is further held in position by means of a sole plate 17 suitably secured as by means of screws 1S to the bottom surface of the club head. The sole plate prevents the displaceiiient of thesci'eiv 16 and the screw 16 in turn, by reason of its being prevented from becoming loosened, holds the impact insert 13 in a iXed relation with the club head. ,lt is to be understood that the securing' means 1G -niay be a pin instead of a screw and that such a. pin will. as effectively secure the relative parts as will the member shown. l

The head 15 of the impact insert 18serves further to hold a plurality of auxiliary iinpact inserts 19 in position in the club head. These inserts 19 are embedded in the body portion of the club head and extend through the face plate 11, the outer end thereof being; flush with the striking' surface of the face plate 17.` The inserts are positioned adjacent the periphery of the impact insert 13. the flanged portion of the head 15 overlapping a con'iparatively small portion of the inserts and being,` countersunk therein. inthe drawing three such auxiliary inserts 19 have been provided, although any number thereof may be provided Which may be of any size in keep. ing With the appearance ot the golf club head and the utility thereof. i

lt is preferable thatthe insert 13 be ofv metahfor theV reason that it affords an absolutely rigid or solid driving surface which, however, is not inert. The material of the inserts 19 is preferablyof ivory or sonic other hard composition which may be distinctively colored and ariane'ed to produce a striking and ornamental It is seen from the foregoing' that the aux?v iliary inserts 19 are securely anchored in the lgolf club head by means of the head 15 ofthe insert 18, and that the latter, in turn, idly fixed in a socket provided in the lower end of the golf club head by means of a screw sitioii such that it cannot become loosened by means o t a sole plate 17.' By thus locking the inserts in position in the golf club head, it is found. unnecessary to provide the inserts With screw threads, glue, or the like, which latter means are undesirable due to the shrinking or expanding' of the material of the golf club head which cracks'the same across the threaded portion upon shrinking; or so looseiis the insert that a solid blow cannot be transmitted to 'the golf ball. Again, it is found very desirable to use a metal insert 13 for the reason that it affords the requisite resistance and solidity which enable the user to continue the stroke after the foi'ec of impact has been transmitted to the ball which in the language of the players is called the follow through?? 7 y Referring' now to Figs. 1, 5 and 6 of the drawings, an impact insert of a inodified'form is shown, although it is substantially the same as that of the previously described insert. In this instance` the insert may be made of a cylindrical. shape having a head portion 20 and a reduced body portion 9.1. A counterbored socket 22 is provided in the face plate 2B ol the club head and extends a substantial iure into the body portion thereof.y The is 'preferably of metal, the outer surface the head portion Q0 being' flush With the striking' su ice of the 'face pltae 23, these latter members being;` inclined rearwardly .troni the lo 'ver edge of the head as is usual in Ompi.' .1,1 .1.t'- T1l' i 1l no i, (1.1i construe ion. n. inscit is ie d in position by means of ar sci'eiv Q4 extending` s from the bottom surface of the club 25 to tlii'eadedlyengage the insert. A sole plate 2G is pro-vided on the bottom surface of the golf club head and is secured thereto by means of screws 27, the sole plate thus lockingV the 'screw 24 in a position such that it cannot beconie. loosened. A plurality of auxiliary inserts. 28 are'disposed adjacent the vperiphery of the reduced portion 21 of the centrally disposed impact insert. the head portion 20 there- Vof overlapping and seatingv in eut-away portions 29 foi'iiied at the outer extremity of the auxiliary inserts. y

iis in'tiie pei'viously described eii'il'iodimcnt,

'these auiziliary inserts 29 may be lformed of ivory ora composition suclitliat they may be easily colored whereby a striking' ornamental en c K4 eiiect may be obtained. These inserts are further disposed so that the vibrations set up Y in the .club may bedistributed throughoutthe club and thereby introduce a harmonious vij bration ofthe head a Whole upon the force of the impact ivith the golf/ball. y Further, in- E asinuch as. the'seeui'ing means, such as the .screws 16 and 2st, Aare locked in position as by means ofthe plat s1? and Q6 respectively, it is to be understo-r'id t t a pin or other like securing' member may be used asv effectively as a n screw. 16, the securing' means being' locked in a pol'TJhile several embodiments of this invention have been herein shown and described. it is to be` understood that many niodiiications lili) thereof may be apparentto one skilledinqthe arttvithout departing` from the spirit .andv
