, Always of paramount consideration in the development of better golf clubs is the weight and balance characteristics thereof. In the golfing instrument described below, there is described a club which will give good directional control to a golf ball and is described in the form of a .putting instrument. However, it will be understood that with some modifications, especially as to slant and size of the striking surface, other golfing clubs can be devised under the scope of this invention.
Another important objective of this invention is to provide a golfing instrument of improved balance and stroke characteristics wherein a normal golfing stroke is utilized and whereby the .user thereof will not be required to learn new techniques.
A still furthersobjective of this invention is to provide a golfing instrument of the type described wherein additional weight is given to the club instrument. without changingits outside dimensions and wherein 'the center of gravity of additional weight will be located at the above-mentioned center of gravity.
Another objective of this invention is to provide a golfing instrument where the sole-drag of the club is reduced well below that of conventional flat-bottomed instruments.
It is yet another object and feature of this invention to provide a golf club, the circular dimensions of which aid in aligning same with the circular dimensions of the golf ball. v
Another important objective of this invention is to provide a golfing instrument which maintains the above-mentioned beneficial advantages even thou the ball to be struck rests on a difficult slope.
Another important objective of this invention is a golf club of the type described which is adapted to be constructed of metallic or molded materials, which is simple :in construction, relatively inexpensive to manufacture and attractive in appearance.
A still further objective of this invention is the provision of a club head wherein the appearance of the hitting face may be readily varied whereby a variety of club heads may be provided, all of which will employ the same general body design.
Another important objective of this invention is to provide a club head which is smooth with the exception golf club of this invention;
of its striking surface and is not impaired with exterior I securing screws and the like.
Another object of this invention is to construct a golfing instrument whereby, when the eyes of the golfer are directly above the ball, the balance, design, and feel of the club will aid the golfer in visualizing his stroke to thus increase accuracy in the path followed by the ball after striking same.
In another embodiment of the golf club of this invention two flattened striking surfaces are provided on a generally spherical, hollow body portion. The flattened surfaces lie in substantially parallel planes on eachside of the loci of the radii of the spherical body portion. The flattened surfaces can be located in diverging planes if lofted striking surfaces are desired and the surfaces are of a diameter slightly greater than that of a standard golf ball. This embodiment is of benefit primarily to those golfers wh'oprefer a blade type putter as opposed to a rounded back type but which retains all of the features set forth above in reference to the first embodiment.
These and other objectives of the invention will become more apparent to those skilled in the art by refer- .ence to the following detailed description when viewed in light of the accompanying drawings wherein:
FIG. 1 is a front view of the golf club of this invention; I
FIG. 2 'is a view similar to FIG. 1 showing .the interior .of the club head;
FIG. 3 is a view similar to FIG. 2 with the addition of weight means;
:FIG. 4 is a side view of the club facing the striking surface;
FIG. 7 is a view in the direction of one of the flat striking surfaces of the golf club of the embodimentof FIG. 6;
FIG. 8 is a view in cross-section taken on lines 8-8 of FIG. 7;
FIG. 9 is a view similar to FIG. 8 with weights positioned in the hollow body; and
The club head 14 is formed with a spherical surface I 16 and a flat striking surface 18 and a connecting member 11. The spherical surface is defined by a plurality of radii 20 having their loci at the point indicated by the letter C. The longitudinal axis 22 of the connecting member 11 passes through point C and the .shaft 12 is angulated to one side or the other depending upon whether the club is to be used bya right-handed or left- .handed golfer. It is important to note that a line .24 normal to the surface 18 and at its geometrical center will also pass through the point C. a i The club head 14 is comprised basically of two elements. The first element is a generally hollow, metallic portion 26, from which the connecting member 11 and shaft 12 extends. The second element is member 30 of a lighter weight than the spherical portion 26 and which encloses the opening 28 of the spherical portion.
Since the spherical body 26 is interrupted in favor of the putting surface 18, the cover 30 is made of a material to insure that the center of gravity of the body falls through the point C when the cover is properly secured to the body 26.
In order that a completely smooth outer exterior surface will be presented, the body 26 is provided with a threaded rod 32, the outer end of which is adapted to be received by a pre-formed hole 34 in member 30. The hole 34 has a depth which will insure that the member 30 is securely affixed to the member 26. The line separating members 26 and 30 is barely visible after being affixed in this manner.
This invention also provides means by which the weight characteristics can be varied in accordance with the particular requirements of the user. In FIG. 3 it can be seen that a plurality of weights 40 are placed on the rod 32. The weights will have a width such that they are snugly secured when member 30 is threaded to proper engagement with member 26.
FIGS. 6 through 9 show another embodiment of the golf club of this invention. In this embodiment the loci of the radii of curvature of the club head and the center of gravity are also coincidental. The club head has a generally spherical body portion 40 and a hollow space 42 therein. The main difference between the club head of FIGS. 6 through 9 and the embodiment of FIGS. 1 through 4 is that instead of the former being provided with one flat striking surface, it is provided with two flat striking surfaces 44 and 46 which are located in planes on either side of the loci or center of gravity C. As shown, the faces are substantially in parallel planes. However, it is to be understood that the club faces can be slanted somewhat as desired. The shaft 12 need be angulated to one side only to accommodate both rightand left-handed golfers.
The cover member for closing the hollow space is indicated by the numeral 48 and is located in the bottom portion of the club head. The cover is substantially round and is in axial alignment with connecting member 11 of the club shaft 12. The cover is secured into the club head in a manner similar to the manner in which the cover 30 is secured to the club head in FIGS.
1 through 4. A rod 50 is attached at one end to the interior wall of the hollow body portion and extends toward said opening in the bottom of the club head. The other end of the rod 50 is threaded to receive the cover 48 and hold it in the closed position such that the outer surface of the cover is substantially flush with the the club head does not substantially affect the center of balance of the club head. The club shaft may be attached to any of a number of points on the club head to suit the personal preference of the user.
In a general manner, while there has been disclosed an effective and efficient embodiment of the invention, it should be well understood that the invention is not limited to such embodiment, as there might be changes made in the arrangement, disposition, and form of the parts without departing from the principle of the present invention as comprehended within the scope of the accompanying claims.
