B. MILLER GOLF CLUB April 11, 1950 Filed Nov. 8, 1946 frwenor. BePnardMi Z Zer' A' o rney Patented Apr. 11, 1950 i 'GOLF .CLUB W Bernard Miller, Seattle, Wash.

"Applieatzion'novmbef's, 1948, serial Nd. 708,711

. 1 My invention relates to improvements in a golf club and has particular 'application to improvement in a putter.l As is well known, a personmay' be putting off line and not be conscious of it. One normally compensates for the fact that the swing is not true by allowing or borrowing one way or another. This is frequently done over long periods of time without knowledge, because it isl sometimes diicult to determine that the putter blade is normal to the line of projected flight.l

Some efiort has been made to correct this difficulty byarranging a' telltale mark longitudinally of the upper edge of the blade parallel to the face so that a longer and truer indication is observable than merely lookingat the top or face of the' putter blade. Other efforts have been made to make the head of the putter thick and arranging a telltale mark at right angles with the plane of the face of the blade, and, also, it is common to provide two marks, one parallel to the face of the' blade and the other normal thereto. The thickness of the blade is a limiting factor and thus a line of insufi'icient length is provided to serve'as a prolongation of the line of flight normal to the face of the blade.

The object of myinvention is to provide a lateral fiange extending rearwardly from the face of the blade, which fiange is approximately as long as the longitudinaldimension of the putter blade. tending its full length, running fromfthe face of the blade to the trailing edge of said flange. Saidtelltale mark lies at the middle and intersects the face of the putter blade at this point and with it forms a T so that the plane of the putter blade and the line of fiight may easily be indicated.,

A further objectof my invention is to provide; aputter having such a fianged telltale' back and-- a conventional back for the putter, which backs' vcntionalback may be used. Said parts are pro' portioned and 'arranged, both with regard -to weight and balance-- 'so that the replacement 'off' the' practice back by theplaying or cont'entionalf back cannot be' detectedfb the swinging of the club or by the feel thereof.` This rrialne'sthepracl ticing device of greater value because the'swihg 'theffe'el'ofcan be v'checked withoutffidisturb the golf c1ub.-'

Sad'fiange'-carries a telltale mark ex-l seated one upon the other, the shaft of Further and other details of my invention are' hereinafter described with reference to the-accompanying drawings, in which:

Fig. 1 is a perspective view of a putter headl illustrating the manner in which the practicing device may be secured to the putter head portion;

said parts being shown alined but separated from' each other;

Fig. 2 is a similar perspective view of said parts said golf club being shown fore'shortened;

fFig'. 3 is a cross-sectional view taken through the line 3-3 in Fig. 2, showing the manner in= whichv a spring-pressed, releasable detent' may' hold the removable and' the fixed portions of 'said' putter'head together; and

Fig. 4l is a view similar to Fig. 3 showing themanner in which a conventional back may replace the practice back When said parts are arranged in play.

A golf club embodying my invention comprises' a shaft I, to which is secured to a head portion 2' by the usual hosel 3. Said head portion may be of any conventional shape. For the purpose of illustration, I have shown a blade-type putter. Said head portion is relieved upon its upper edge' to define a rear shoulder 4 and a forward shoulder' 5. The central or median portion 6 lying between them is narrower than the thickness of said blade and i's shorter than the overall length of the putter blade. Extending vertically or transversely of said blade and across the back thereof is a" Vertical recess 1, the sides of 'which are tapered so as to provide a pair of dovetailed edges 8.' Extending transversely of the central portion 6 are a pair of spring-pressed' detents 9 which normally' extend beyond the rearward surface of the central portion for' the purpose of engaging and' holding either o'f'the two removable Sections VIll' and Il. The' removable section ll] has a'rearwardlyextendingiliplz formed thereon. Upon the upper surface thereof is a telltale line 13 lying normal to the face of the head portion, which also coincides with the forward edge |2a of the lip |2. Said telltale line lies intermediate the ends of said lip` and at the portion 2.'

' Said rearWardIyeXtending'lip is s'ubstantiallyl as long'as'fthe 'length of the putter blade. Thus`- said telltale line |3 forms a T'with' the'forward-I edge' of the lip 12;' and said 'telltale line'would'lie upon thei line of fii'gl'it of t'he'ball if .the ball were' struck by'the center of the face'of the head por-.1: tion 2, which' is'to'be des'ired; Said lip I'Z'lies'lat?` the'upper edge of the puttin'g'" face 2a". It'isV to middle of the face ofthe head:`

acoaesoe be noted that the shoulder at the forward side of the putting blade is higher than the one at the lower side. This provides a greater width for the face 2a of the head portion so as to assure the ball being struck by the head portion 2, rather than the forward edge |2a of the rearwardly extending lip. Said lip has a forwardly extending flange Id and a rearwardly extending fiange |5 with relation to the plane of head portion 2, which are complementary to the shoulder portions 4 and' 5 of the head portion. Thus, as is shown in Figs. 1, 2 and 3, said flanges M and IE fit closely within the shouldered portions 4 and 5 of the head and form therewith smooth, uninterrupted faces both forwardly and rearwardly of the putter blade.

ward extendlng lip has a dlsposition of mass and weight comparable to that of the section I l, and

The'spring-pressed detents fit into apertures IiS in the adjacent face of the rearwardly extending flange l5 and hold said parts together so aslto prevent any play or rattle. Said member IO also has a vertically extending section Il, which is provided with tapered or dovetailed marginal sides so that they will fit within and engage the complementarily formed edges 8 in the head portion 2.

Lying at the end of said section ll is a boss 18, which lies below the lower edge 2b of the head portion. Said boss preferably is roundedso as to slide easily over the ground, but extends a slight distance beyond said edge so that the removable back may easily be removed from engagement by the detents by striking it on the ground or upon a hard surface, which will force the member ID upwardly and' disengage the latter from the head portion. That is to say, if the putter is arranged with the under surface lying upon the ground or upon a hard surface, the parts may be disengaged merely by exerting pressure on the shaft'or by striking said boss I 8 upon the ground or upon said hard surface, which will force the member l' upwardly and the springpressed ball detents 9 out of the apertures, respectively, in which said balls seat when the parts are in engagement. Said detents lie substantially equidistant from and at oppositeV sides of the Vertical section ll and its recess 1 in the head portion. Thus, there are three'points of contact: the two spring-pressed detents 9 and the engagement of the dovetailed edges. There is some give in the detents because said balls are urged into frictional engagement with their recesses by coiled springs 9a seated within recesses 9b in said head portion. Said resilient pressure tends to prevent any play from occurring, as well as to prevent the physical disengagement of said parts.

When one wishes to use said putter to determine whether his swing is true, the member IO is seated upon the head portion of the putter in the manner illustrated in Fig. 2. The lengths of the telltale mark or line 43 'provide sufilcient visual indication to determine whether or not' the putter. is being swung so that it moves in a straight path in the line of the projected fiight of the golf ball. If the telltale mark tends to move out of alinement or to be oscillated during theputting swing, then the player hasvisually brought to his attentlonv that his stroke is faulty and he thus can practice until his putting swing is smooth, even and theputting face is. alwaysat right'angles to the intended course of the. golf ball which is to'be struck by said face.

It probably would be undesirable to use said putter in actual play, and thus, ifV desired, said4 member Ill may be removed and a conventional back portion H substituted therefor, as is illus'- trated in Fig. 4. The section IO with the rearthus a player could use either of said sections interchangeably without feeling or sensing the difference. The change may easily be made merely by applying pressure upon the boss |8, as has been described, but said parts will never become loose as long as said detents engage their respective apertures. Also, there is little likelihood of inadvertent detachment of said parts. Because the sections IO and ll both straddle the upper edge of the end portion, the latter supports the weight of said sections IO or II. The fact that the head is made of two pieces is difiicult to discern excepting by looking at the toe of the putter whereitheparting lines are apparent, as is shown in Fig. 2. To maintain proper balance and weight, I' have found it desirable to make the section ID and the rearwardly extending lip out of some light'weight metal such as an aluminum alloy, While the section II, to produce greater mass and compactness, preferably is made of some heavier metal such as brass, steel or iron. The Sections. and particularly the inner-related parts, are made of 'substantial Sections and would thus not become easily damaged so that they wouldnot interflt. If the latter should occur, play might be produced and difiiculty of separation or seating the sections IO or ll upon the head portion 2. Some slght wear ortdistortion of said parts might be accommodated because the resliency of the Springs 9a would take up some slight play or unequal engagement or bearing of the parts adjacent the inner-fitting surfaces of the head and the sections Ill and ll.

In several views, I have added detent 9c which seats in a recess in the lower end' of the doVetailed slot at the middle of the vertically extending connection l'l'. It is possible to provide three of these detents to eliminate play, but. normally either the pair of detents should be provided to force the back into tight engagement with the dovetailed slots, or the detent Sc should be used alone to shift said Vertical section I'l laterally in the dovetailed slot to produce the same result. If they are used alternatively, it provides that one of the legs of said three-point support will bind metal to metal in unyielding abutment. If all three are utilized, it will force all of the opposed faces of the butter blade and the removable back into abutment, and if they are not exactly plane and parallel, it might produce some unevenness, which is undesirable.
