Golf putter head

Abstract

The putter head includes a putter head member formed of a first material having a given weight per unit volume. The putter head member has an outer side wall which includes a top portion, a bottom portion and first and rear second ends with an axis extending between the first and second ends. An aperture is formed into the putter head member between its first and second ends parallel with the axis and located closer to the bottom portion than to the top portion. A rod is located in the aperture. The rod is formed of a second material having a weight per unit volume greater than that of the first material. An aperture is formed in the top portion along a plane parallel with the axis for attachment of a shaft.

1 . A golf putter head, comprising: 
 a putter head member formed of a first material having a given weight per unit volume,    said putter head member having an outer side wall comprising a top portion, a bottom portion, and first and second ends, with an axis extending between said first and second ends,    an aperture formed into said putter head member between said first and second ends parallel with said axis and located closer to said bottom portion than to said top portion and,    a rod located in said aperture,    said rod being formed of a second material having a weight per unit volume greater than the weight per unit volume of said material of said putter head, and    means located at said top portion along a plane parallel with said axis for attachment of a shaft.    
     
     
         2 . The putter head of  claim 1 , comprising; 
 indicia formed on said outer side wall of said putter head member at said top portion on opposite sides of said plane and at the same distance from said plane for alignment purposes in using said golf putter head.

 first and second grooves formed in said outer side wall at said first and second ends respectively in planes transverse to said axis.    
     
     
         4 . The putter head of  claim 1 , wherein: 
 said first material is aluminum,    said second material is brass.    
     
     
         5 . The putter head of  claim 2 , wherein: 
 said first material is aluminum,    said second material is brass.    
     
     
         6 . The putter head of  claim 3 , wherein: 
 said first material is aluminum,    said second material is brass.    
     
     
         7 . The putter head of  claim 1 , comprising: 
 indicia formed on said outer side wall of said putter head member at said top portion on opposite sides of said plane and at the same distance from said plane for alignment purposes in using said golf putter head,    first and second grooves formed in said outer wall at said first and second ends respectively in planes transverse to said axis.    
     
     
         8 . The putter head of  claim 7 , wherein: 
 said first and second ends each comprises first and second round end caps with said first end caps being located outside of said second end caps respectively.    
     
     
         9 . The putter head of  claim 7 , wherein: 
 said first material is aluminum,    said second material is brass.    
     
     
         10 . The putter head of  claim 9 , wherein: 
 said first end caps are formed of aluminum and said second end caps are formed of brass.
