referring now to fig1 a , a golf club c having a shaft s and a head h is shown . the facing f is that part of the head h which contacts the golf ball ( not shown ). the groove or slot g is shown in fig2 . this slot g has a depth d and a width w . the slot g is channel - shaped such that the width w is constant over the depth d . in this way the slot g resembles an open - ended box - type structure . the facing f contains a number of slots g machined , embossed , cut or engraved onto its face . in the preferred embodiment , the depth d of the slot g is about 0 . 020 inches and the width w is about 0 . 080 inches . the distance l between the successive slots is about 0 . 080 inches . in fig1 a the face f of the head h is machined with two sets of slots g . the first of these sets is comprised of a number of parallel vertical slots 10 engraved , machined embossed or cut into the facing f of the head h . the second of the sets of slots is comprised of a number of horizontal parallel slots 12 engraved , machined , embossed or cut into the facing f of the head h . the intersection of these slots , 10 and 12 , creates the appearance on the facing f of a number of rectangles . fig1 b likewise shows two sets of parallel slots . the slots in fig1 b are not , however , horizontal and vertical in direction as in fig1 a . slots 14 are parallel to each other . the slots 14 are at a diagonal on the face f in which the angle between a vertical line and the diagonal is a positive angle . the slots 16 are likewise parallel to each other and on a diagonal , but the angle with the diagonal is negative rather than positive relative to an x , y coordinate . when viewed from the front of the facing f , the intersections of the sets of slots , 14 and 16 , resembles a number of diamonds on the facing f . fig3 a and 3b show a detachable facing f of a golf club . in fig3 a and 3b a number of holes 18 are drilled through the facing f in order to provide a means for fastening the facing f to the club c . fig3 a has a set of vertical and horizontal slots , creating a number of rectangles , similar to fig1 a . fig3 b has a set of diagonal slots , creating a number of diamond shapes as is shown in fig1 b . in fig4 the slots g and the facing f have a layer of hard chrome plating p deposited on them . this plating p is used to provide a hard , wear resistant , attractive surface for the facing f . this plating p is generally resistant to scratching , cutting , or nicking . in the preferred embodiment of the invention the plating p would have a thickness of approximately 0 . 004 inches . this plating p would be deposited on the facing f and the slots g after the slots g have been engraved , machined , embossed or cut into the club head h . the series of slots g engraved into the facing f are relatively wide when viewed relative to their depth d . a golf ball is a relatively hard , wound or solid , ball covered with a slightly resilient material . when the club c strikes the golf ball the golf ball flattens to some extent . as the golf ball is flattened the series of slots g mesh with and contact with the resilient covering of the golf ball . the facing f and the slots g have a combined surface area greater than that of the facing f alone . it is this greater surface area which is in gripping contact with the golf ball covering . this greater surface area yields a greater gripping contact with the resilient covering . this greater gripping contact results in better control over the spin imparted to the ball . by controlling the spin of the ball , the tendency to slice can be eliminated . the hard chrome plating acts to preserve and protect the inter - connecting slots and to thereby lengthen the useful life of the golf clubs . while this invention has been described as having a preferred design , it is understood that it is capable of further modification , uses and / or adaptations of the invention following in general the principal of the invention and including such departures from the present disclosure as come within known or customery practice in the art to which the invention pertains , and as may be applied to the central features hereinbefore set forth , and fall within the scope of the invention of the limits of the appended claims .
a facing for a golf club having a series of channel - shaped spaced apart slots , said slots having a width of approximately 0 . 080 inches ; said slots having a depth of 0 . 020 inches ; and the distance between each set of slots being approximately 0 . 080 inches is disclosed .
