V. E. MORRISON GOLF CLUB Filed March 1, 1954 Jan. 21, 1958 INVENTOR VAUGHN E. MORRISON :ATT YS United States atent GOLF CLUB Vaughn E. Morrison, Batavia, Ill.

Application March 1, 1954, Serial No. 413,310

4 Claims. (Cl. 273-164) This invention relates to golf clubs and finds particular application in the provision of a new and improved putter.

An object of the invention is to provide a golf club that will assist the player in making accurate shots.

Another object is to provide a golf club which is balanced in such a manner that it facilitates accurate approaching and, particularly, putting.

A particular object is to provide a club which is balanced about the gripping portion of the shaft, ordinarily also about the longest axis of the shaft, to minimize club head turning and deviation from the proper are in the course of hitting the ball.

An additional object of the invention is to provide a golf club having the club head and the shaft or shank thereof so constructed as to facilitate alignment of the players head with the ball and the hole.

A further object of the invention is the provision of a golf club having a mark on the top of the club head and having the lower portion of the shaft, or shank portion, inclined from the vertical whereby the player can assume the proper stance by aligning his eyes with the shank to automatically bring his head over the mark on the club head in the proper position for addressing the ball.

A still further object is to provide a golf club both balanced and constructed to assist in properly aligning the players head with the ball and the hole.

These and other objects and advantages of the invention will become apparent from the following description taken in conjunction with the accompanying drawing in which like reference characters are employed in each of the views to identify like parts, and in which:

Figure 1 is a broken elevational view of a putter embodying the invention;

Figure 2 is a plan view of the putter head taken on line 2-2 of Figure l;

Figure 3 is a left profile view of the putter head broken away in the upper portion of the shaft, taken on line 33 of Figure 1;

Figure 4 is an elevational view of another embodiment of the invention, illustrating a putter head and a separate shank member attached to the head, with parts of the construction broken away; and

Figure 5 is an elevational view of a golfer addressing the ball with the putter of Figure 4.

As illustrated in the drawing, a golf club embodying the invention comprises a club head and a shaft, including a gripping portion, connected thereto, the longitudinal axis of'the gripping portion being approximately coincident with the center of gravity of the club. The club is thus balanced in the golfers hands when it is swung, so that there is no or practically no torque acting about the axis of the gripping portion to cause the head to turn around the axis, and consequently move the face of the club head out of its proper plane. The construction also assists in avoiding deviation from the proper arc of swing during backward and forward movement of the club until contact is made with the ball and during the followthrough.

The advantages of the invention are best realized when the club shaft lies in a vertical plane, and the top of the club head is provided with an aligning mark over, or directly above, the center of gravity of the club, so that the ball contacts the face of the club head substantially at the point on the face nearest the center of gravity.

A further feature of the invention is the provision of a shank portion in the club shaft, or of a separate shank, extending upwardly from the club head for a substantial distance at an acute angle to a horizontal plane through the top of the club head. The part of the shank portion facing the toe of the club head has a straight sighting portion, preferably a flat surface, forming a slight acute angle from the vertical in the direction of the toe which serves as a sighting or aligning surface for the golfer. When the golfers eyes arealigned with this sighting surface, his head is in the proper position over the aligning mark. A right triangle is thus formed between the golfers eyes and the sighting portion as the hypotenuse, the golfers eyes and the aligning mark as one of the sides, and the mark and the base of the sighting portion as the other side.

In the embodiment shown in Figure 1, a putter 1 includes a metal club or putter head 2 and a metal shaft 3 suitably united with the head at the base of the shaft, as by screwing, welding or expansion. The shaft 3 includes a lower relatively short generally vertical circular shank portion 4 and a relatively long upper circular portion 5 terminating in an uppermost gripping portion or handle 6. Around the gripping portion there is tapewound or otherwise afiixed a suitable material 7 such as leather or a composition serving to provide a grip for holding the club.

In Figure l, the shaft 3 is continuous from the club head to the uppermost end of the shaft and is in the form of a bent tube, preferably widening upwardly along the shaft, as represented in Figure 5. A separate shank 4' may be employed, as illustrated in Figure 4, the shank be ing adapted at its upper end for connection to the remainder of the shaft unit. This facilitates the manufacture of a club furnishing the sighting feature, discussed in greater detail hereinafter.

The putter 1, and particularly the shaft 3 thereof, is constructed so that the longitudinal axis 8 of the gripping portion 6 of the shaft, which is also the axis of the entire upper portion 5 of the shaft in the form shown, is approximately coincident with the center of gravity of the putter, identified as C. G. in the drawing. Some deviation from exact coincidence of the axis 8 of the gripping portion and the center of gravity is permissible while still accomplishing the objects of the invention; however, greatest accuracy is assured when the axis is substantially coincident therewith. Correspondence between the axis 8 and the center of gravity can be obtained by suitably constructing and joining the club head 2 and the shaft 3..

For this purpose, the club head may be weighted or lightened, such as by drilling or otherwise providing one.

or more holes in the club head and filling them with a heavy or light metal.

The base of the shank portion 4 of the shaft 3 is disposed toward the heel 9 of the club head 2. The shank portion extends upwardly and generally vertically from the head and unites with the upper portion 5 of the shaft,

which extends upwardly and outwardly from the shank The longitudinal axis 15 of the shank portion portion. 4 and the longitudinal axis 8 of the upper portion 5 of the shaft form an obtuse angle 0 directed toward the heel 9' of the club head 2, to properly position the club head in relation to the body of the golfer. The shaft 3, particu larly' the longitudinal axes 15 and 8 of its components; lies in a single vertical plane paralleling the longitudinal axes of the club head 2 and its face 14 and perpendicular to the direction of the hole,'when in the proper position for putting;

The top or upper surface 10 of the head 2*is provided with three spaced parallel straight grooves 11', 12 and 13,

which are substantially normal to' the face 14of the club head, the face being inclined from the vertical to provide a small pitch; The central groove'1'2 is over, or directly above, the center of gravity of the putter 1 and fulfills the purpose of the aligningmar'k previously-referred to, i. e., it is the groove sighted on bythe golfer and'aligned behind the center of the ball and in the direction of the hole. The grooves 11 and 13- are optional and assist in obtaining the proper centering.

The sole 16 of the club head 2 preferably has slightly rounded'edges. 17 and 18' (see Figure 3) along the face 14 and the back 19, respectively, of the head andalso has rounded edges 29 and 21 toward the heel 9 and the toe 22 respectively, of the head. This construction mini: mizes interference with the turf while providing a level lie, so that the upper surface 10 of the head 2 is forms an angle a of about 37 to 89 with the-upper surface 10 of the club head when the latter is constructed so thaton assuming its natural lie, the upper surface is in a horizontal plane. Otherwise stated, the sighting portion 23 forms an angle with the vertical of about 1 to 3 when. the club assumes its natural lie. The base line distance b from the central groove 12 on the upper surface*10" to the base24 of the sightin'g'portion 23: is then about 1% to 1% inches, preferably about 1%; inches,

so that the triangle shown-in-Figure has its upper apex atthe proper-level.

Where there is'provided a shorter base line distance b between the central groove 1=2-on -the clubhead-Z and,

the base of the surface 23 ofthe-shank' portion- 4 facing thetoe 22, asshownin Figure 1, the-corresponding angle a between the upper surface of the-club'head and the surface 23 of the shank portion willibe acute but-greater,

if the sighting feature is desired, to provide a sighting triangle of the proper height. Itis preferred forgreatest accuracy, h'owevento construct the clubso that the base the gripping portion (corresponding; to the constructionof Figure 1),, is coincident with the center. of gravity of the club. However, the construction providingthe aligning'fe'atu're of the invention is also useful alone andmay be provided in golf clubsconstructed without the balancing feature.

The'l'ongitudinal axis ISof the shank portion ortshank 4 forms an obtuse an'gle'c"with the longitudinal axis 8 oil the upper portion 5 of the shaft unit or shaft 3. The angleflcorrespond's'. to the angle c'in the form illustrated in Figure 1, except that the angle 0 is slightly smaller dilel to the increased inclination from the vertical of 'theshan'lrv portion 4', forming the angle a" Which is slightly smallerthan the-angle a shown in Figure" 1".

In'tlie'form shown, the upper'portion of a shank meni- 4 her 25 including'the shank 4' has a hollow shaft receiving portion 26' adapted for insertion of the remainder of the shaft 3' into the shank member, for connection thereto. The shank member 25' is shown'as welded to the club head 2', to provide an assembly which accurately fixes the angle a between the sighting portion 23 of the gravity of the club and in front of the face 14 of the club head during alignment and at contact, by means of the central groove 12 and the auxiliary grooves 11 and 13 on the upper surface 10 of the club head. Durihg the backswing, forward motion of the club, contact with the ball and foll'ow through, the golfer is assisted in avoid ing club hea'df turni'ng,ancl deviation from the proper arc of swing, toin'cr'eas'e the accuracy of the shot.

When using the embodiment of Figures 4 and 5", which also assists" in properly'positioning the golfers head the central marl? of, groove 12' on the upper surface 10' of the club'he'a'd 2" lS'CCfltlCl'bfihlIld the ball 27, andt'hef sole 1 6" of means head is allowed-to taker its'natural' lie. The golfers eyes are the r aligned along a'si'ghting" line- 28* with the flatisu'rfaee sighting portion 23 of'the shank 4'. This brings the g'olferseyes directly over the central roove 12 iii the upp'e'r's'urface of the club head, so that a vertical line ofsight 29 can be'd'rawn'betweeh the eyes" and the roove I2; The grooves 1 1'" and 13, on either-side of the ceh tr al g'roove 12' assist in p'rop'erly" centering the ball. In this way; the golfer is able to properly align'the putter, the balland the hole and to anchor his head in the proper'po'sitior'i to putt the balli Although the inventionis especially useful as applied to putters, it, and particularly the balancing feature, can also be applied to other golf clubs. tageously employed in clubs customarily played from a" close stance such as approach irons, 6, 7, 8 and 9 irons; and sandblasters.
