Abstract
A golf putter having a forward wall forming a putting face, a portion of reduced thickness behind the wall, a slot in the rear portion of the wall perpendicular to the putting surface, a cavity having a portion underlying the slot, and an exposed portion rearwardly of the wall occupying a major portion of the vertical dimension of the putter and having a marker line spaced downwardly from the upper surface of the slot and visible through the slot to form an alignment sight.
Claims5
A golf ball putter comprising:
- a. a putter blade having a forward putting face, a rear face and upper and lower faces;
- b. a recess in said blade extending forwardly from said rear face, said recess having upper and lower surfaces adjacent to but spaced from said upper and lower faces, to define rearwardly extending upper and lower flanges respectively, and a forward surface parallel to said putting face;
- c. a slot through said upper flange extending rearwardly from at least said forward surface of said recess perpendicular to said putting face and communicating with said recess and being of a depth no greater than said upper flange and defining a reference edge at its juncture with said forward surface, said reference edge being spaced upwardly from said lower surface substantially the full height of said recess;
- and
- d. a reference line on said lower surfsce extending parallel to said putting face and being below said slot to be visible therethrough and spaced rearwardly from said forward surface of said recess a sufficient distance such that said reference line remains in full view and undergoes apparent forward-rearward displacement with respect to said slot and reference edge as the golfer moves his head, respectively, forwardly or rearwardly.
