Description
FIELD OF THE INVENTION
This invention relates to golf clubs and more particularly to the head of a golf putter having provision for altering the overall weight and the distribution of the weight of the putter.
BACKGROUND OF THE INVENTION
The weight of the head of a golf club and the location of its centre of gravity are well known to affect a golfer's swing. The weight of the head for example, affects the force of impact of the swing which in turn affects the distance that a ball travels assuming that the head hits the ball squarely. The greater the force of impact of the head at the time of impact with the ball, the longer will be the length of a shot, again assuming that the ball is hit squarely. The force of impact is governed by the strength of the player and the weight of the head.
For a given player the weight of a head is the governing factor for obtaining the maximum possible distance.
The weight and centre of gravity can be customized at the time of manufacture of the golf head to take into account such variables as the position of a golf club, the angle of swing of a club, the length of the handle of the club and the particular strength and ability of a golfer.
Some known golf clubs have provision for adjustment of the weight and centre of gravity of their heads so that a golfer can made adjustments between swings and, as needed, to take into account any changes that may occur in his swing. An example of such a golf club is described in U.S. patent no. 6,923,734 to Meyer where the head of the club is provided with internal tubular passages for receipt of weighted rods. The weight and centre of gravity of the head can be I
adjusted by altering the position of the rods.
A shortcoming of the Meyer golf head is that it has a complicated structure owing to its internal passages. As a result, the manufacture of the head is time consuming and expensive. An additional shortcoming is that adjustment in the position of the weighted rods is not a simple matter. Adjustment requires a tools and a significant amount of time.
SUMMARY OF THE INVENTION
I have invented a putter in which adjustments to the weight and centre of gravity of its head can be made quickly and without special tools. Moreover the head has a very simple structure and is very economical to construct. Briefly the putter head of my invention includes a toe member having an elongated striking surface oriented normal to the direction in which the head is adapted to swing. A heal member extends to the rear of' the toe member and terminates at a rear surface.
One embodiment of the putter of my invention has an opening in its rear surface. The opening has a cylindrical inner wall, the longitudinal axis of which coincides with the vertical plane of symmetry of the putter. The head includes a number of plugs of differing weights each one of is being adapted to be accommodated in the opening.
Another embodiment of my putter has provision for the attachment of a number of rods of differing weights each one of which being adapted to be attached to the rear surface of the putter. The longitudinal axis of the rod coincides with the vertical plane of symmetry of the putter.

Like reference characters refer to like parts throughout the description of the photographs and drawing.
DESCRIPTION OF PREFERRED EMBODIMENTS
With reference to Figure 1, the head of the putter, generally 8, includes a toe member 10 having an elongated striking surface 12 and a lower wall 14. A heal member 16 extends to the rear of the toe member and terminates at a rear surface 18. A handle 20 extends upwardly from
3 the head.
With reference to Figures 1 and 4, the head is symmetrical about a vertical plane 22-22 referred to below as the "vertical plane of symmetry". The longitudinal axis of the handle lies on the vertical plane of symmetry and is perpendicular to the plane of the lower wall 14 of the head.
The plane of the striking surface 12 is perpendicular to the vertical plane of symmetry of the head. The angle between that plane and the lower wall 14 of the head, marked 24 in Figure 1, may vary from about 90 degrees to about 87 degrees. Thus the lower edge of the striking surface may extend further forward than the upper edge of the striking surface.
With reference to Figure 2 to 5, an opening or cylindrical passageway 30 commences at the rear surface 18 and extends into the body of the heal member. The opening has a cylindrical inner wall 32, the longitudinal axis 34-34 of which lies on the vertical plane of symmetry of 22-22 of the head. That axis also lies on the direction of swing 36 of the club.
Opening 30 is adapted to receive a plug 40. Threads 42 are formed on the outer wall of the plug for threadable mating with the threads (not illustrated) on the inside wall of the opening With reference to Figure 6, a collar 50 is attached by screws or by welding to the rear surface 18 of the heal member. The collar has a central threaded opening for threadable receipt of a rod 52 which extends to the rear of the heal member. The longitudinal axis of the rod lies on the vertical plane of symmetry of the head.
The plug and rod may be made of plastic but preferably is composed of a heavier metallic
With reference to Figures 1 and 4, the head is symmetrical about a vertical plane 22-22 referred to below as the "vertical plane of symmetry". The longitudinal axis of the handle lies on the vertical plane of symmetry and is perpendicular to the plane of the lower wall 14 of the head.
The plane of the striking surface 12 is perpendicular to the vertical plane of symmetry of the head. The angle between that plane and the lower wall 14 of the head, marked 24 in Figure 1, may vary from about 90 degrees to about 87 degrees. Thus the lower edge of the striking surface may extend further forward than the upper edge of the striking surface.
With reference to Figure 2 to 5, an opening or cylindrical passageway 30 commences at the rear surface 18 and extends into the body of the heal member. The opening has a cylindrical inner wall 32, the longitudinal axis 34-34 of which lies on the vertical plane of symmetry of 22-22 of the head. That axis also lies on the direction of swing 36 of the club.
Opening 30 is adapted to receive a plug 40. Threads 42 are formed on the outer wall of the plug for threadable mating with the threads (not illustrated) on the inside wall of the opening With reference to Figure 6, a collar 50 is attached by screws or by welding to the rear surface 18 of the heal member. The collar has a central threaded opening for threadable receipt of a rod 52 which extends to the rear of the heal member. The longitudinal axis of the rod lies on the vertical plane of symmetry of the head.
The plug and rod may be made of plastic but preferably is composed of a heavier metallic
4 material such as steel. Such material will add significantly to the overall weight of the head. The weight can be adjusted to the particular needs of a golfer by obvious means such as by increasing or decreasing the length of the plug and rod or by forming the plug and rod of lighter material such as nickel, copper and alloys of these and other metals. Where a heavier head is required, the plug and rod can be composed of as lead or alloys of lead.
The centre of gravity of the head can be adjusted simply by rotating the plug and rod to cause it to move further into or further out of the opening in the case of the plug and further toward and away from the head in the case of the rod. Since the longitudinal axis of the plug and rod lie on the vertical plane of symmetry of the head, such movement of the plug and rod will not affect the balance of the head.
It will be understood that plugs and rods of different material and lengths can be used to tailor the weight of the head to the specific needs or wishes of an individual golfer.
The opening for the plug need not be confined to the rear surfaces 18 of the heal member.
The opening for the plug may be formed in the upper wall of the heal member and even on the upper wall of the toe member. Provided the longitudinal axis of the opening lies on the vertical plane of symmetry of the head, the plug will serve to alter the centre of gravity and the weight of the head. Similarly, the rod may also extend upwardly from the upper wall of the toe or heel members of the head. So long as its longitudinal axis lies on the vertical plane of symmetry, it too will serve to alter the centre of gravity and weight of the head.
Figure 7 illustrates the golfer's stance immediately prior to striking the golf ball. The golfer is striking from the left side of his body and his left foot 60 is behind his right foot 62. The head 64 of the putter is to the left of his left foot and the golfer has twisted his body slightly counter-clockwise so that he can grasp the handle of the putter with both hands. The golfer will use his left hand to strike the ball 66 and his right hand to steady the putter.
The position of the feet and the function of the hands will be reversed should the golfer strike the ball from the right of his body.
It will also be understood that other modifications can be made in the structure of the head, plugs and rods of the invention without departing from the scope and purview of the invention as defined in the appended claims.
