Patent ID: 8615858

Claim:
An extraction apparatus used to remove a golf club head from a golf club shaft, the apparatus comprising: a cylinder and piston assembly comprising a piston means and a cylinder body, the cylinder body having a cylinder bore in which the piston means moves, the cylinder bore having an intersection with a plane perpendicular to the direction of movement of the piston means which defines a bore cross section and this bore cross section is approximately an annulus having a center, an inner circle, and an outer circle; a sealing means which provides a pressure seal between the piston means and the cylinder bore; a cylinder bore pressurization means; and a shaft clamping means; wherein the cylinder and piston assembly is placed on the golf club shaft by passing the shaft through the inner circle of the annulus, the shaft is held by the shaft clamping means, and the cylinder bore is pressurized pneumatically or hydraulically, thereby applying a force to the piston means; whereby the apparatus urges the head to move away from the shaft.
