the preferred embodiment of the present invention will be described herein with reference to an illustrative embodiment of a marked golf ball and a golf ball stencil which follows . referring to fig2 there is shown the golf ball stencil of the present invention generally referred to as numeral 2 . the stencil is generally of the shape of a hollow hemisphere , which may be shaped , molded , or formed from plastic , metal , or any combination of similar useful materials . as illustrated , this preferred embodiment comprises two slits 4 a and 4 b disposed crossing each other at their midpoints and forming a 90 ° angle . disposed below slit 4 a , another slit 5 a is formed . this third slit 5 a , which differentiates my prior art stencil from this embodiment , makes it easier for the golfer to align the putter blade correctly , since this third slit 5 a allows the user to draw a second line , which is closer to the putter blade . surprisingly , it has been found that the addition of this third slit 5 a appears straight and parallel to line 4 a on he stencil drawing . after marking the golf ball and upon closer inspection of the marked golf ball , line 4 a appears to trace the curvature of the golf ball surface . however , when a golfer is looking down on the ball , during a putting stroke for example , line 4 a appears to be a straight line . this straight - line appearance is accomplished because of the round spherical shape of the golf ball . the presence of two apparently parallel lines allow the golfer to easily align the putter face properly , by permitting easy visualizing of the correct blade alignment needed for proper putting . this “ double - line ” visual impact was totally unexpected , as the simple two - line markings formed by use of my spot liners product ( u . s . pat . no . 6 , 004 , 223 ) has been critically acclaimed as being a very useful product , earning the product a three - star rating from golf magazine . in the opinion of many golfers who have tried both versions , the new and improved marking device of the present invention far surpasses the original spot liner ® marking device . in a most preferred embodiment , the slits are approximately ⅛ inches wide , and will accommodate a marking instrument such as a felt tip pen . in addition , the spacing of the two parallel slits 4 a and 5 a in the most preferred embodiment is about ½ inches ( from centerline to centerline ), with the shorter of the two parallel slits being about 1 inch in length . referring to fig3 the golf ball 8 was marked using the stencil 2 described above . in fig3 golf ball 8 has three markings 7 a , 7 b , and 9 a . markings 7 a and 7 b intersect to form a crosshair on the golf ball . marking 9 a is parallel to marking 7 a . markings 7 a and 9 a assist the golfer in contacting the ball with the club face . preferably , the club face contacts the golf ball parallel and square to markings 7 a and 9 a to move the golf ball in the direction of marking 7 b . for playing purposes the markings might be formed by , for example , marking with a pen or marker such as a sharpie ® pen , spray painting , airbrushing , stamping , etching , scoring , or any other method for imparting indicia to a surface using the stencil as a guide . in a preferred manner of use , the golfer would mark a ball before play , using a permanent felt - tip marking pen or the like . for example , different colored markings may be used by member of a foursome to distinguish each ball in play . in utilizing the ball , the present invention is particularly useful to assist the golfer in putting . the markings can likewise serve to assist driving , as well as fairway shots , as the indicia on the ball assists the golfer in getting the head of the golf club squared to the intended line of ball path direction . referring to fig4 a second illustrative embodiment is disclosed . the embodiment comprises all of the elements of the golf ball stencil embodiment described hereinabove with the addition of a loop 10 which can advantageously be used to secure the marking stencil to the golf bag or other utility hook for easy access and convenient storage . additionally , loop 10 can be used as a point of reference . of course , many other securing means may be used in the place of the loop including but not limited to hooks , strings , cords , or clips . referring to fig5 a third illustrative embodiment is disclosed . the embodiment comprises all the elements of the golf ball stencil embodiment described hereinabove , except line 5 a has been placed closer to the portion of the ball that is contacted . one skilled in the art would recognize that line 5 a may be placed anywhere parallel to line 4 a . placement of line 5 a closer to the putter face allows for easier visualization and a higher probability that the putter will contact the golf ball at the correct orientation . additionally , line 4 a may intersect line 4 b at a point other than the midpoint of line 4 b . for example , line 4 a might be moved closer to line 5 a and the surface contacted by the putter to aid the golfer in contacting the ball . alternatively , line 4 a may be moved further away from line 5 a . other orientations , shapes and sizes are possible . the stencil can comprise unequal - length and / or width slits and may form more detailed indicia or graphics . as shown in the dotted lines in fig6 line 4 a may be shorter than line 5 a . as shown in fig7 the lines may be shaped in other geometric shapes such as triangular . additional shapes , such as triangular shapes , rectangular shapes , circular shapes , spherical shapes , and combinations thereof , may aid alignment of the face of the putter with the golf ball for more accurate hitting . additionally , better visualization of the golf ball markings may be achieved using geometric shapes other than lines . although the invention has been shown and described with respect to exemplary embodiments thereof , various other changes , additions and omissions in the form and detail thereof may be made therein without departing from the spirit and scope of the invention .
a marked golf ball and an alignment aid for golfers consisting of a rigid hemispherically shaped body having three slits therein for making a mark on a golf ball which indicates the intended path of the golf ball and the preferred orientation of the club face for obtaining the intended path of the golf ball .
