Golf Putter

Abstract

A golf putter head having adjustability in weight and center of gravity. The putter head has a ball-striking front portion with a club face defining its width and height, a heal, a toe, and top and bottom surfaces defining the length of the front portion. The putter head has a front central axis extending through the center of gravity of the front portion and parallel to the top and bottom surfaces. A weight-and-balance-adjustment rear portion is connected to the front portion, which has a plurality of lengthwise-extending housings. Each housing includes an internal cavity constructed and arranged to removably contain at least one weighted slug. The putter head has a first center of gravity when the internal cavities are empty. The first center of gravity can be moved along the length, width and height of the putter by inserting weighted slugs in one or more of the cavities.

1 . A golf putter head comprising:
 a. a ball-striking front portion having a club face defining the width and height of said putter head, a heal, a toe, and top and bottom surfaces defining the length of said front portion, and a front central axis extending through the center of gravity of said front portion and parallel to said top and bottom surfaces;   b. a weight and balance-adjustment rear portion connected to said front portion having a plurality of lengthwise-extending housings relative to said club face, each housing including an internal cavity with a cavity central axis and constructed and arranged to removably contain at least one weighted slug,   wherein said putter head has a first center of gravity when said internal cavities are empty, and,   wherein said first center of gravity can be moved along the length, width and height of said putter by inserting weighted slugs in one or more of said cavities.   
     
     
         2 . The golf putter head recited in  claim 1 , wherein the central axis of at least one of said plurality of housings is arranged at a different height, and the central axis at least one of said plurality of housings is arranged at a different width, relative to said central axis. 
     
     
         3 . The golf putter head recited in  claim 2 , wherein the central axis of each of said cavities is parallel to said front central axis. 
     
     
         4 . The golf putter head recited in  claim 1 , wherein said plurality of housings are symmetrically arranged about said front central axis. 
     
     
         5 . The golf putter head recited in  claim 1 , including a plurality of metal slugs, each having a shape and size that complements the shape and size of said cavities. 
     
     
         6 . The golf putter head recited in  claim 6 , wherein said slugs have the same size but at least one slug has a different weight than another slug. 
     
     
         7 . The golf putter head recited in  claim 1 , wherein said cavities include removable end caps for inserting or removing said slugs from said cavities. 
     
     
         8 . The golf putter head recited in  claim 1 , further comprising a runner fixed to the bottom of a plurality of said housings and extending generally parallel to send front central axis. 
     
     
         9 . The golf putter head recited in  claim 8 , wherein said runners resist rotation of said putter head by their frictional pressure against the ground when said putter head is grounded. 
     
     
         10 . The golf putter head recited in  1 , wherein said front portion and back portion have a unitary construction. 
     
     
         11 . The golf putter head recited in  claim 1 , including a center housing extending laterally rearward from and integral formed with said front portion and equidistantly-opposed side housings extending laterally rearward from and formed integral with said front portion. 
     
     
         12 . The golf putter head recited in  claim 11 , wherein said side housings are symmetrically positioned about said center housing and parallel to each other. 
     
     
         13 . The golf putter head recited in  claim 11 , wherein said center housing is positioned more rearward and closer to the bottom of the putter head than said side housings. 
     
     
         14 . The golf putter head recited in  claim 1 , wherein said club face has a first textured surface on its face in a ball striking area, and a second textured surface outside of the ball striking area.
