Abstract
Abstract A novel construction for a golf club is described. The club head is cylindrical in shape and of circular cross-section, the curved wall of the cylinder being used as the ball striking surface. Manually replaceable weight assemblies are releasably secured in each end of the cylindrical head, the respective weight assemblies being selectable to provide the desired balance and feel for the player. The shaft is connected to the head by a malleable neck portion which can be bent by the player to provide the desired angle of the shaft to the head to suit his stance. The diameter of the club head is such as to result in the application of overspin to the ball when struck and its length is approximately equal to the diameter of the cup. The club is especially suited for use as a putter, although it can be used with facility for chipping from longer grass surrounding the greens.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
199 words
A golf club having a shaft and a head, the head comprising a tubular member having a smooth outer ball-contacting surface, a pair of manually removable weight assemblies, one of said weight assemblies being releasably secured within each end of said tubular member, each of said weight assemblies comprising a first cup-shaped element of resilient material having a radial flange extending about the periphery of its open end, the outer diameter of said first cup-shaped element being such as to securely retain the weight assembly within said tubular member with the end of the latter abutting the radial flange on said cup-shaped member, and the outer diameter of said radial flange being substantially the same as the outer diameter of said tubular member, a weight member of preselected weight securely retained within the first cup-shaped element adjacent its closed end, and a second cup-shaped element having an outer diameter such as to be securely retained within said first cup-shaped element and a length such that when inserted in said first cup-shaped element its closed end is substantially flush with the open end of said first cup-shaped element, and means connecting said shaft to said tubular member intermediate its ends.
Claim 2
Dependent Claim
199 words
A golf club having a shaft and a head, the head comprising a tubular member having a smooth outer ball-contacting surface, a pair of manually removable weight assemblies, one of said weight assemblies being releasably secured within each end of said tubular member, each of said weight assemblies comprising a first cup-shaped element of resilient material having a radial flange extending about the periphery of its open end, the outer diameter of said first cup-shaped element being such as to securely retain the weight assembly within said tubular member with the end of the latter abutting the radial flange on said cup-shaped member, and the outer diameter of said radial flange being substantially the same as the outer diameter of said tubular member, a weight member of preselected weight securely retained within the first cup-shaped element adjacent its closed end, and a second cup-shaped element having an outer diameter such as to be securely retained within said first cup-shaped element and a length such that when inserted in said first cup-shaped element its closed end is substantially flush with the open end of said first cup-shaped element, and means connecting said shaft to said tubular member intermediate its ends.
Claim 3
Dependent Claim
78 words
The golf club according to claim 1 wherein said means connecting said shaft to said tubular member includes a rod member bendable, when assembled in the golf club, by application of manual forces as augmented by the leverage provided by the club head and shaft, whereby a player can set the angle between the shaft and head to a desired value by proper application of manual forces but said angle will not change under normal conditions of use.
Claim 4
Dependent Claim
71 words
The golf club according to claim 1 wherein the radial flanges on the weight assemblies in the respective ends of said club head have axial lengths short with respect to the axial length of the tubular member and are of a color that contrasts sharply with the color of said tubular member, thereby presenting to the eye of the player when in use a pair of easily distinguishable spaced parallel markers.
