Golf club head having a tensile pre-stressed face plate
First Claim
1. A golf club head for use with a golf club comprising a body, a planar face element engaged to said body and spaced therefrom, and a rim formed about an exterior surface of said body adjacent a portion thereof, and adapted to engage said face element, wherein said face element, at least in its central area, is in a substantially, tensile, pre-stressed condition engaging said body, adapted to stiffen said face element and reduce the indentation of the same during its impact with a ball during play.

Abstract
A golf club head comprising a body and a face plate coupled with the body wherein the face plate has a permanent tensile pre-stress, created in the manufacturing process, which is generally radial outward from the central area of the face plate towards the boundary which stiffens the face plate and reduces indentation of the plate when it impacts with the golf ball during play.

- 1. A golf club head for use with a golf club comprising a body, a planar face element engaged to said body and spaced therefrom, and a rim formed about an exterior surface of said body adjacent a portion thereof, and adapted to engage said face element, wherein said face element, at least in its central area, is in a substantially, tensile, pre-stressed condition engaging said body, adapted to stiffen said face element and reduce the indentation of the same during its impact with a ball during play.

10. A golf club head for use with a golf club comprising a body, a planar face element engaged to said body and spaced therefrom, and a rim formed about an exterior surface of said element adjacent a portion of said body and adapted to engage said face element, and wherein said face element, at least in its central area, is in a substantially, shrink-fit induced, pre-stressed condition engaging said body, adapted to stifffen said face element and reduce the indentation of the same during impact with a golf ball during play, said face element including an edge flange, and being arranged for overlapping said rim of said body along where said face element and said body are joined, whereby said body can support said face element after said shrink-fitting.

11. A golf club head for use with a golf club comprising a planar face element engaged to said body and spaced therefrom, and a rim formed about an exterior surface of said body adjacent a portion of said body and adapted to engage said face element, and wherein said face element is in a substantially, tensile, pre-stressed condition engaging said body, adapted to stiffen said face element and reduce the indentation of the same during its impact with a golf ball during play, said face element being formed with an edge flange wherein said edge flange is fixed to said rim of said body along the section where said face element and said body are joined, whereby said body can support said face element with a tensile pre-stress.
- 12. A golf club for use with a golf club comprising a body having peripheral rims and a planar face plate facing the direction a ball travels after impact thereof, said peripheral rims being arranged to join said face plate rigidly to and spaced from said body, said face plate being substantially pre-stressed engaging said body extending approximately outwardly towards said peripheral rims from a central area of said face plate, said face plate being adapted to contact and partially envelop the impacting ball directly surface to surface, offering a large contact surface, forming a greater force resultant to resist the advance of the ball due to the presence of the pre-stress, thereby effectively reducing the indentation of the ball during play.
