Such markings 6, 6, a club head, having the markings or scorings of though normally inclined, are thrown, under the my invention. conditions above described, into substantially Figs. 2 and 3 are foreshortened views of the horizontal position, and h c a e ab e to im- 45 same head as it appears, respectively, in a facedpart to the ball practically as much backspin as back condition and in a faced-forward condition. would have been imparted under the most favor- Like reference characters refer to like parts able conditions,that is, with the undeflected in the different figures. club face engaging the ball in the, zone of the I have chosen for the illustration of my invenmarkings 4, 4. tion a golf club incorporating the invention of Inwardly of the markings 4, 4, the club face, Ogg and Storz Patent'No. 1,917,774, dated.

This inclination of these inner markings l, 1 is such as to compensate for errors in a players swing that cause the club face, at the moment of impact, to assume the position shown in the foreshortened view of Fig. 3,that is, with the outer or toe portion ahead of the socket or hosel l (by too much turning in the direction of arrow B), and the face tipped forwardly into a plane more nearly vertical than that occupied by the face in Fig. 1. Under these conditions, the impact with the ball is almost invariably made by the inner portion of the hitting face,"
and the markings E, l on said inner portion, though normally inclined, as shown in Fig. 1, are thrown by this last-described deflection of the hitting face into a substantially horizontal position, as shown in Fig. 3; hence the ball, when so struck, will have imparted to it practically as much backspin as would have been imparted if it had been'struck correctly by the markings 4, 4, as the result of a normal or perfect swing.
It will thus be seen that the face markings of my invention are able to impart substantially maximum backspin to the ball, regardless of whether or not the swing is properly executed, and regardless of whether or not the hitting face of the club, at the moment of impact, occupies a plane atright angles to the desired line of flight of the ball. Not only that, but said improved face markings are so arranged as to be of great benefit to the player, from the standpoint of sharply delineating and definitely indicating the zone or area of maximum hitting effect on the club face, because in addressing the ball, the player, looking down on the club face from above, is readily able to distinguish the horizontal markings 4', 4 of the central zone of the face from the inclined markings 6, E5 and 7, 'l of the outer and inner face zones, respectively.
1. A golf club head or blade having, in a central zone of its face, scorings substantially parallel to the sole of said head, the outer zone of said face having scorings at such an inclination to the first-named scorings that when the club head arrives at the bottom of the swing in a facedbackward position (Fig. 2), said outer zone scorings, which then become effective on the ball, tend to assume a position substantially horizontal or parallel with the ground, thereby imparting substantially as much back-spin as though the ball had been struck by the central zone of the club face.
2. A golf club head or blade having, in a central zone of its face, scorings substantially parallel to the sole of said head, the inner zone of said face having scorings at such an inclination to the first-named scorings that when the club head arrives at the bottom of the swing in a faced-forward position (Fig. 3), said inner zone scorings, which then become effective on the ball, tend to assume a position substantially horizontal or parallel with the ground, thereby imparting substantially as much back-spin as though the ball had been struck by the central zone of the club face.
3. A golf club head or blade with a set of substantially horizontal face markings in a central zone thereof, there being a second set of slightly inclined markings in an outer zone of the club head face, the inclination of said second set of markings being such that they tend to assume a substantially horizontal relation when the club head at the bottom of the swing faces backwardly (Fig. 2) and there being a third set of slightly inclined markings in an inner zone of the club head face, the inclination of said third set of face markings being such that they tend to assume a substantially horizontal relation when the club head at the bottom of the swing faces forwardly (Fig. 3).
