Peripheral weighted golf ball for putting training

Abstract

A training golf ball apparatus having an asymmetrical weighting or cavity means extending from proximal the center of the training golf ball to proximal the surface. The weighting or cavity means has a density different from the general density of the training golf ball. A guideline circumference marks the surface of the training golf ball along a circumference which, if the training golf ball was bisected, would reveal radial symmetry of the weighting or cavity means. An orthogonal guideline circumference, orthogonal to the guideline circumference, marks the surface of the training golf ball along a circumference which, if the training golf ball was bisected, would reveal radial symmetry of the weighting or cavity means.

       3 . A training golf ball ( 1 ) apparatus of  claim 2  further comprising: 
 a the weighting means or cavity means ( 200 ) is further defined, along the guideline circumference ( 220 ), by a weighted or cavity means guideline circumference angle Θ ( 250 ) from the center ( 100 ) to the extremity of the weighted or cavity means ( 200 ) at the position where the guideline circumference ( 220 ) bisects the weighting or cavity means ( 200 ) and, a weighted or cavity means orthogonal guideline angle Φ ( 252 ) along the orthogonal guideline circumference ( 240 ) at the position where the orthogonal guideline circumference ( 240 ) bisects the weighting or cavity means ( 200 ).    
   
   
       4 . A training golf ball ( 1 ) apparatus of  claim 3  further comprising: 
 a the weighted or cavity means guideline angle E ( 250 ) is within the range of degree to 359 degrees; the weighted or cavity means orthogonal guideline angle Φ ( 252 ) is within the range of 1 degree to 359 degrees.

 a the weighting means or cavity means ( 200 ) is geometrically symmetrical;    
   
   
       7 . A training golf ball ( 1 ) apparatus of  claim 6  further comprising: 
 a the weighting means or cavity means ( 200 ) is formed of at least one plug, at least one wedge or at least one truncated hemisphere composed of materials of a density which is either greater then or lesser than the general density of the spherical ball ( 10 ).    
   
   
       8 . A training golf ball ( 1 ) apparatus of  claim 7  further comprising: 
 a the weighting means or cavity means ( 200 ) is composed of metals, plastics or cavities;    b the guideline circumference ( 220 ) and the orthogonal guideline circumference ( 240 ) provide a sighting means for the golfer.    
   
   
       9 . A training golf ball ( 1 ) apparatus of  claim 8  further comprising: 
 a a putter head ( 500 ) striking the training golf ball ( 1 ) without inducing spin, when a putter stroke direction ( 600 ) is aligned with either the guideline circumference ( 220 ) or the orthogonal guideline circumference ( 240 ) will cause the training golf ball ( 1 ) to travel in a straight line;    b the training golf ball ( 1 ), when propelled with the putter head ( 500 ) positioned for a putter stroke direction ( 600 ) not coincidental with the guideline circumference ( 220 ) or orthogonal guideline circumference ( 240 ) will travel in a curved path illustrating visual training for the practicing golfer;    c the guideline circumference ( 220 ) and the orthogonal guideline circumference ( 240 ) are each composed of a broken or solid line partially or wholly circumnavigating the training golf ball ( 1 ).
