Abstract: A unique golf club putter head having a fluted rear mass design. This rear mass is shaped as a concave mass that merges with the sole of the blade and dips just below the sweet spot of the head at the center thereof. It lowers the center of gravity of the head along the sweet spot while also controlling the mass at heel and toe. Fluting the rear mass permits controlled variation in the distribution of the mass from heel-to-center-to-toe so that it doesn't overwhelm the ball-hitting surface and instead produces stable smooth roll.

Abstract: An improved golf club wedge configured for reliable ball contact out of deep rough and other difficult lies, employs a striking surface leading edge that precedes the hosel by a significant onset. Nevertheless, the wedge hereof hits the golf ball along a lower and longer trajectory than its closest predecessor by reducing the distance from the hosel/face center line to that leading edge along both the striking face and the sole. Moreover, the wedge of the present invention uses a bigger bounce as well, which gives the head a more acceptable appearance and makes it more compatible with other clubs in a set of golf clubs.

Abstract: A slipper-shaped head cover that is especially designed to facilitate convenient installation onto a golf club head after the golfer has made a shot. A preferred embodiment comprises a surface referred to herein as the sole because of the slipperlike configuration of the head cover. The sole is connected to a pair of opposed flaps along respective sides and to a heel along one end. An upper encloses the heel and forms a pocket for receiving the head of a golf club. The upper is affixed to a rear for fully enclosing the golf club head. The upper also terminates in a stiffening lip which holds the pocket open when the flaps are fully opened and separated so that the head cover can readily accept the golf club head. When the golfer removes the head cover from a club, he or she lays the cover on the ground nearby. The sole rests on the ground and the flaps are fully opened revealing the pocket under the upper.

Abstract: A metal wood golf club head providing a shaft attachment to the interior of the head at the interior surface of the sole, permits an unencumbered face surface even adjacent the heel. The resulting head provides improved off-center shots in an external configuration that has no hosel.

Abstract: The head and shaft of golf clubs are mechanically isolated from one another by a dampening ferrule made of a rubber-like material and installed around the shaft where the shaft attaches to the head such as at the hosel. The ferrule in a disclosed embodiment is configured as a hollow cylinder having an internal passage for tight-fit engagement with the shaft and an external radial surface for tight-fit engagement with the golf club head. Preferred materials for the dampening ferrule include Neoprene, Delrin, Nylon, plastic polymers and other rubber-like substances.

Abstract: A unique golf club putter head having an enlarged, substantially planar, slightly convex sole plate and a narrow bridge-like top member thereby lowering the center of gravity of the putter head. This lowered center of gravity is more readily exploited to achieve an accurate stroke by providing connection of the golf club shaft directly to the sole plate along the center-line of the putter head adjacent the face. This connection is facilitated by a hole in the top member bridge through which the hosel extends to receive the lower end of a shaft.

Abstract: A method of fabricating a wax casting of a golf club iron head including the steps of providing a wax injection tool having a rear cavity projection; providing a collapsible insert that is shaped to provide a desired undercut peripheral region in the rear cavity of the wax casting; installing the collapsible insert on the periphery of the rear cavity projection of the tool; injecting hot wax into the tool and allowing the wax to harden; then removing the hardened wax and insert from the injection tool; and finally removing the insert as a unitary member from the hardened wax, without requiring any form of breakage of the wax casting or the insert such as by distorting its shape.

Abstract: Apparatus for molding hollow metalwood golf club heads of wax or other material with variations in the lie angle of the neck or hosel relative to the body of the club head, in which two molds with communicating mold cavities are supported for turning of one mold about a pivotal axis to change the angular relationship of the two cavities. The molds have arcuate abutting surfaces coaxial with the pivot for effective meeting relationships in the different positions, the hosel base being slightly oversize to accommodate the displacement, and two core pieces in the molds have part-spherical abutting surfaces, also coaxial with the pivot for effective "kissing off" of the parts. The movable mold is detented in one of eight different positions, in one-degree increments. Another embodiment produces solid-headed irons with selected different lie angles of the hosel, but with only one core piece, which is in the hosel mold.
