Weight interchangeable putter

Abstract

A weight interchangeable golf putter is provided having a T shaped head. The head has a main body constituting the main weight and a striking face. From the trailing edge of the top surface a center tail extends rearward to form the T shape of putter plane. At the sides of the tail there are formed end fins with their free ends opened rearward to better guide the putter head through the air during the stroking address. The top of the back weight extends to near midway of the length of the tail and merges with the bottom of the tail. The back weight has a bottom surface in flush with the corresponding bottom of the main body and terminates with an end wall tapered gradually toward the main body to avoid hitting the ground when strokes are made. Three cylindrical bores are formed facing the same backward direction in the common 90-degree angle from the rear wall to receive different metal screws. When the screws are in their initial positions the putter with its face balanced neutralizes the leftward pulling or rightward pushing in the putting of the right-handed golfer who tends to show more pulling problems. Balance adjusting at the day's practice rounds or putting will be rightfully done with ease and no special tool thanks to the protruding screw design which provides an extra visual aid as well as a structural indicator of the invisible sweet spot to improve the actual approach of the ball into the hole cup.

1 . A golf putter comprising: 
 a. a putter head constituting the main weight of the putter, the putter head having a striking face, a top surface extending parallel to the ground and having an opening near its one end to accommodate a shaft with a double bend leading to a grip, a center tail extending rearward from the top surface in perpendicular to the striking face and a couple of threaded side bores opened at the opposite surface of the striking face at both sides of the center tail;    b. a back weight branching centrally perpendicular to a main body of the putter head having a top surface extending to near midway of the length of the tail and merging therewith and a bottom surface lying in flush with the corresponding bottom of the main body and terminating with an end wall tapered gradually toward the main body, the back weight also having a center bore identical in shape, size and direction to the side bores; and    c. a group of three elongated screw weights made to have an identical dimension of different metals for giving distinctive weight values in the putter at the bore locations, whereby the center tail provide the principal aligning aid for the correct directional putting by the golfer while the straight extensions of the side screw weights provide an extra visual aid as well as a structural indicator of the invisible sweet spot of the putter.    
   
   
       2 . The golf putter set forth in  claim 1 , wherein the elongated screw weights are made of materials selected from a group consisting of tungsten, white bronze, silicon bronze and aluminum.  
   
   
       3 . The golf putter set forth in  claim 1 , wherein the center tail is painted with white to give a contrasted line on the green ground for promoting a visual alignment to correct the travel of the ball before striking.  
   
   
       4 . The golf putter set forth in  claim 1 , wherein the putter has a T shape.  
   
   
       5 . The golf putter set forth in  claim 1 , wherein the golf putter has three weight ports.  
   
   
       6 . The golf putter set forth in  claim 1 , wherein the putter has a T shape and has three weight ports.  
   
   
       7 . A golf putter comprising: 
 a. a putter head having a striking face, a top surface and a hosel to accommodate a shaft leading to a grip, and threaded side bores on each side of the putter head behind the striking face;    b. a center tail extending rearward from the top surface, perpendicular to the striking face;    c. two screw weights of similar dimension and made of different metals for giving distinctive weight values in the putter at the bores; wherein the center tail forms a straight directional visual aid while the screw weights provide tuning capability to adjust the sweet spot of the putter.    
   
   
       8 . The golf putter set forth in  claim 7 , further comprising a back weight branching centrally perpendicular to the putter head having a top surface extending from the midway of the tail and merging therewith and a bottom surface lying in flush with the corresponding bottom of the putter head and terminating with an end wall tapered gradually toward the putter head, wherein the back weight also has a center bore identical in shape, size and direction to the side bores.  
   
   
       9 . The golf putter set forth in  claim 8 , wherein the elongated screw weights are made of materials selected from a group consisting of tungsten, white bronze, silicon bronze and aluminum.  
   
   
       10 . The golf putter set forth in  claim 8 , wherein the center tail is painted white to give a contrasted line on the green ground for promoting a visual alignment to correct the travel of the ball before striking.

 a. a putter head having a striking face, a top surface and a hosel to accommodate a shaft leading to a grip, and threaded side bores on each side of the putter head behind the striking face;    b. a center tail extending rearward from the top surface, perpendicular to the striking face;    c. two screw weights of similar dimension and of different weights for giving distinctive weight values in the putter at the bores; wherein the center tail forms a straight directional visual aid while the screw weights provide tuning capability to adjust the sweet spot of the putter.    
   
   
       13 . The golf putter set forth in  claim 12 , further comprising a back weight branching centrally perpendicular to the putter head having a top surface extending from the midway of the tail and merging therewith and a bottom surface lying in flush with the corresponding bottom of the putter head and terminating with an end wall tapered gradually toward the putter head, wherein the back weight also has a center bore identical in shape, size and direction to the side bores.  
   
   
       14 . The golf putter set forth in  claim 12 , further comprising a back weight branching centrally perpendicular to the putter head having a top surface extending from the midway of the tail and merging therewith and a bottom surface lying in flush with the corresponding bottom of the putter head and terminating with an end wall tapered gradually toward the putter head, wherein the back weight also has a center bore identical in shape, size and direction to the side bores.  
   
   
       15 . The golf putter set forth in  claim 12 , wherein the elongated screw weights are made of materials selected from a group consisting of tungsten, white bronze, silicon bronze and aluminum.  
   
   
       16 . The golf putter set forth in  claim 12 , wherein the center tail is painted white to give a contrasted line on the green ground for promoting a visual alignment to correct the travel of the ball before striking.
