Golf club head
First Claim
1. A hollow golf club head of the type known as a "metal wood" for playing the game of golf, said club head havinga backwardly slanting striking face having an inner surface and an outer surface, andan opposing rear portion having an inner surface and an outer surface,a substantially flat-faced body having a stem portion having an axis protruding centrally from a rear thereof and substantially normal to the plane of said flat face, said face being rigidly bonded to said inner surface of said striking face,wherein said stem engages in an axially slidable manner the hollow of an open-ended, internally-threaded tube having a screw therein, said tube engaging said inner surface of said rear portion and said screw threadably engaging said tube and applying an axial compressive force to said stem and an equal and opposite axial compressive force to said tube, the magnitude of said compressive force may be adjusted by turning said screw.

Abstract
A hollow golf club head for a "metal wood" is disclosed wherein an internally-mounted backing plate gives strength and stability to the striking face of the club. Additionally, in the preferred embodiments, an internal apparatus is present whereby the backing plate is compressively loaded to more rigidly support the striking face of the club, thereby to make it more unyielding upon impact with a golf ball. In further embodiments, weights may be added behind the backing plate in alignment with an axis that is normal to the center of the striking face.

11. A hollow golf club head of the type known as a "metal wood" for playing the game of golf, said club head having
a backwardly slanting striking face having an inner surface and an outer surface, and an opposing rear portion having an inner surface and an outer surface, a substantially flat-faced rigid backing plate, the flat face of which is disposed against said inner surface of said striking face, and wherein said rigid backing plate further comprises a stem portion having an axis protruding centrally from the rear of said backing plate and substantially normal to the plane of said flat face, and wherein said stem engages in an axially slidable manner the hollow of an open-ended, internally-threaded tube having a screw therein, said tube engaging said inner surface of said rear portion and said screw threadably engaging said tube and applying an axial compressive force to said stem and an equal and opposite axial compressive force to said tube, the magnitude of said compressive force may be adjusted by turning said screw.
