Method and means for monitoring site of impact of a golf ball on a golf club

Abstract

A method and means for determining the site of impact of a golf ball on any golf club is disclosed and described. It requires only application to the ball and requires nothing be done to the club.

I claim:  
     
         1 . A method for determining the site of impact on a golf club, suitable for use during an actual round of golf, comprising the steps of: impacting any golf club onto a standard golf ball having a dry coating, resistant to moisture, heat, and impact force, which has been applied with a solution having a film forming property which contains, a resin a plasticizer, a colorant, and a rapidly evaporating organic solvent to cause a readily removable mark on the head of the golf club at the site of impact, said mark being readily removed at will by wiping the golf club head.  
     
     
         2 . The method of  claim 1 , wherein the golf club is initially examined and is substantially clean in order to receive said mark from said impact in order to determine the site of impact.  
     
     
         3 . The method of  claim 2 , wherein the golf club head is cleaned after each impact with said coated golf ball.  
     
     
         4 . The method of  claim 2 , wherein the golf club head is not cleaned after each swing, in order to determine and compare the point of impact on successive swings.  
     
     
         5 . Means for determining the point of impact of a golf club head on a golf ball comprising any standard golf club, a golf ball having a dry, substantially permanent outer coating containing a resin, a plasticizer, a colorant, all suspended in an organic solvent to cause a wipably removable deposit of the ball coating on said impact surface at the point of impact thereof on the golf ball, said readily removable deposit being erasable as by being wiped, said club head and said ball being constructed in the manner of conventional golf play.  
     
     
         6 . The means of  claim 5 , where said resin is acrylic resin.  
     
     
         7 . The means of  claim 6 , wherein said acrylic resin is present in the range of 4-20% w/w.  
     
     
         8 . The means of  claim 5 , where said plasticizer is triacetin, acetyl tributyl citrate, tributyl citrate, polyethylene glycol or pthalate esters.  
     
     
         9 . The means of  claim 8 , wherein the plasticizer is present in the range of 9-11% w/w.  
     
     
         10 . The means of  claim 5 , wherein said colorant is an aluminum lake, iron oxide, or titanium dioxide.  
     
     
         11 . The means of  claim 10 , wherein the colorant is present in the range of 1-10% w/w.  
     
     
         12 . The means of  claim 5  wherein said solvent is methanol, ethanol, acetone, isopropanol, or any organic acetate.  
     
     
         10 . The means of  claim 5  wherein said, substantially permanent outer coating is able withstand the heat and elongation force of impact of a golf club on a golf ball without losing the molecular integrity of film forming properties, which would result in cracking or chipping of the film.
