A putter type golf club includes an arrangement for altering the lie angle between the shaft and the club head body. The hosel is formed with a lower flange member which fits into and is pivotably moveable within a slot formed in the top of the club head body. A set screw, cooperating with a series of depressions, locks the hosel flange member in a preselected position.

Golf club head

A golf club head having a sole configuration comprising a four-way diamond cut wherein the extremity of the sole is a peak substantially centrally located on the keel of the sole with four adjacent planar surfaces angled upwardly and outwardly toward the body of the club head. The four surfaces form four linear junction lines extending angularly upward away from the peak.

A cavity back iron with vibration dampening material in the cavity. The material is a polyurethane having a hardness of 20-50 Shore D, a flexural modulus of 1,000-50,000 p.s.i., a percent elongation of 100-600, and a tensile strength of 2,000-8,000 p.s.i.

Cavity back iron with vibration dampening material in rear cavity

A set of golf club irons, each iron including a striking face, a cavity in the back of the club, and a vibration dampening support bar extending between the lower and upper edges and within the cavity. The distance between the center of the support bar to the end of the cavity at the heel of the iron decreases from the less-lofted irons through the more lofted irons. The center of gravity of all of the clubs is substantially at the center of the striking face of the club.

Iron with progessive back cavity support bar

A wood type golf club formed of a shaft and head assembly, the head assembly including a hollow main body portion and an insert coupled thereto along the majority of its periphery by a dovetail to preclude lateral and downward movement of the insert with respect to the main body portion, the main body portion having a ramp extending outwardly from its face with the adjacent face of the insert having a recess positioned to receive the ramp thereby precluding the movement of the insert upwardly away from the main body portion and further including an adhesive coupling the insert to the main body portion.

A composite golf club shaft and the method of constructing the shaft is disclosed. The hollow circular shaft includes a standard butt end having a constant outside diameter along a length of the shaft and a tip end having a constant outside diameter sustantially larger than the tip of a standard shaft, with the constant diameter of the tip end and butt end extending along predetermined lengths of the shaft. An intermediate section of the shaft tapers between the diameters of the butt and tip ends. The shaft is manufactured by wrapping a group of circumferential sections about a mandrel, each layer comprising either standard modulus carbon-graphite fibers or fiberglass fibers in a matrix, with the finished product being heat-cured to produce a golf club shaft.

Large-tip composite golf shaft

A golf shaft selectively reinforced with a composite outer shell substantially shorter in length than the golf shaft. A single shell is molded at a selected location over the shaft. The location of the shell controls the kick point of the golf shaft. The shell is comprised of a reinforced polymeric composite.

Golf club grip

An improved steel golf shaft formed in a generally cylindrical configuraiton with a tip end and a butt end, the shaft having a central aperture extending axially the entire length thereof, three sets of steps continuously decreasing in diameter externally and internally from the butt end to the tip end, the steps of the central set being spaced from each other by a distance greater than the distance between the steps of the other sets. Also disclosed are the matched sets of clubs, woods and irons, employing such shafts as well as their methods of fabrication.
