FIELD OF THE INVENTION [0001] 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 [0002] 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 ball is hit 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. [0003] 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. [0004] 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. Pat. 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 adjusted by altering the position of the rods. [0005] 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. [0006] SUMMARY OF THE INVENTION [0007] 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, is symmetrical about a plane of symmetry and includes a toe member having an elongated striking surface oriented normal to the plane of symmetry and to the direction in which the head is adapted to swing. A heel member extends to the rear of the toe member and terminates at a rear surface. [0008] One embodiment of the putter of my invention has a cavity in its rear surface or its upper surface. The cavity has a cylindrical inner wall, the longitudinal axis of which coincides with the plane of symmetry of the putter head. A number of differing weights is each adapted to be accommodated in the cavity. [0009] Another embodiment of my putter has provision for the attachment or a number of differing weights to the outside surface of the rear or upper surfaces of the putter head. Each weight is symmetrical about a plane and that plane is co-planar to the plan of symmetry of the putter head when the weight is attached to the putter head. DESCRIPTION OF THE DRAWINGS [0010] The putter head of the invention is described with reference to the drawings in which: [0011] FIG. 1 is a perspective view of the front of the head of the putter in conjunction with a shaft for a handle; [0012] FIG. 2 is an elevation of the putter head and shaft; [0013] FIG. 3 is a perspective view of the rear of the putter head and shaft; [0014] FIG. 4 is a plan view of the position of the golfer's feet and the position of the putter head immediately prior to being swung. [0015] FIG. 5 is a perspective view of a second embodiment of the putter head and shaft; [0016] FIG. 6 is an enlarged perspective view of a third embodiment of the heel member of the putter head. [0017] Like reference characters refer to like parts throughout the description of the drawings. DESCRIPTION OF PREFERRED EMBODIMENTS [0018] With reference to FIG. 1, the head of the putter, generally 10 includes a toe member 12 and a heel member 14 which extends from the rear of the toe member. A shaft 20 of a handle extends upwardly from the putter head. [0019] The toe member has an elongated striking surface 22 on its front wall. The surface is flat and lies on a plane 24. The upper edge 22a of the striking surface is straight while the lower edge 22b has a flat central portion 22c and flat upwardly sloping side edges 22d,e. [0020] With reference to FIG. 2, the shaft has a longitudinal axis 20a-20a. That axis is parallel to and spaced apart from an imaginary line 26 which, intersects plane 24 of the striking surface. Plane 24 is oriented such that the angle 28 between that plane and line 26 is between 0 degree and about 3 degrees. It will be observed that when the angle is greater than 0 degree, the angle is downwardly opening so that the lower edge 22b of the striking surface is ahead of the upper edge 22a.
