US 2006/0142095 A1 · Adjustable weight putter

Abstract

An adjustable weight golf putter is provided with a body portion of a material of low specific gravity, for example aluminum, and a weighted cap, receivable in a longitudinal recess opening at the back extremity of the body portion. The weighted cap is formed of a material of high specific gravity, for example a tungsten-copper alloy, and has a weight which is at least more than 20%, and preferably more than 30% of the weight of the lighter body portion, concentrating the weight of the putter head toward the back and locating its center of gravity more than half way toward the back of the putter head. The weighted cap is secured by a threaded shaft engageable in a recess extension in the body. Optional weighted discs, of a high specific gravity material and each of a different weight, are threadedly engageable with the shaft and are usable in various combinations for optimal weight adjustment. The optional weights are applied in tight engagement with the weighted cap, to maintain weight concentration at the back.

Dependent claims

An adjustable weight golf putter which comprises

(a) a putter head having a ball-striking face of predetermined width and a body portion extending rearwardly from said striking face for a distance equal to a substantial fraction of said predetermined width,
(b) said body portion being formed of a relatively low specific gravity material and having a longitudinal axis disposed in perpendicular relation to said ball-striking face,
(c) said body portion having a cylindrical recess therein, open at a back extremity of said body portion and extending forwardly therein along said longitudinal axis,
(d) a weighted cap, formed of a material of substantially greater specific gravity than said body portion, received in back extremities of said cylindrical recess and closing said recess,
(e) said weighted cap having a threaded shaft fixed to a forward end thereof and extending forwardly therefrom along said axis,
(f) said body portion having a recess extension therein at a forward end of said cylindrical recess for closely receiving and confining a forward end portion of said threaded shaft,
(g) one or more disc-like weights having a diametrical dimension to be closely received within said cylindrical recess and each having a central threaded opening for selective threaded reception on said threaded shaft,
(h) said disc-like weights being formed of a material of substantially greater specific gravity than said body portion and being positioned in substantially abutting relation to said weighted cap.

An adjustable weight golf putter which comprises

(a) a putter head having a ball-striking face of predetermined width and a stem portion extending rearwardly from said ball-striking face at right angles thereto,
(b) said stem portion having a longitudinal axis intersecting said ball-striking face in a central portion thereof and having a width substantially less than the width of said ball-striking face,
(c) a body end portion joined with a rearward portion of said stem portion and extending rearwardly therefrom,
(d) said body end portion having a width greater then the width of said stem portion and less than the width of said ball-striking face,
(e) said body end portion having a cylindrical recess therein, open at a back extremity of said body end portion and extending forwardly therein along said longitudinal axis,
(f) a weighted cap, formed of a material of substantially greater specific gravity than said stem and body end portions, received in back extremities of said cylindrical recess and closing said recess,
(g) said weighted cap having a threaded shaft fixed to a forward end thereof and extending forwardly therefrom along said axis,
(h) one of said body end portion and said stem portion having a recess extension therein at a forward end of said cylindrical recess,
(i) said recess extension being threaded for engagement with a forward end portion of said threaded shaft for securing said weighted cap in said body end portion,
(j) said weighted cap having a weight of at least about 20% of the combined weight of said ball-striking face, said stem portion and said body end portion.
