UNITED STATES JAMES ABRAM GARFIELD AITKEN, OF HOLYOKE, MASSACHUSETTS.

GOLF-CLUB HEAD.

Application filed January 17, 1925; Serial No. 3,133.

To all whom it may concern:

Be it known that I, JAMns A. G. ArrnnN, a citizen of the United States, and a resident of Holyoke, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Golf-Club Heads, of which the following is a specification.

My present invention relates generally to 19 golf clubs and more particularly to golf irons and the markings of the striking faces of such clubs, my object being the marking of iron clubs by means of straight grooves in such manner that the users playing ability will be materially enhanced, without infringing the rules and without violating the ethics of the game or in general those of good sportsmanship.

In carrying out my invention I so arrange straight grooves or markings as to produce an indicating area shaded with respect to the surrounding area for several purposes all of which have in mind improvement in the users play in the respects and for the reasons which I will now proceed to describe.

In the accompanying drawing illustratiug my present invention and forming a part of this specification,

Figure 1 is a front elevation showing a club head marked in accordance with my invention, and

Figures 2 and 3 are vertical transverse sections taken respectively on lines 2-2 and 33 of Figure 1.

Referring now to these figures I have shown the head of what is commonly known as an iron club, generally indicated at and including a blade whose striking face 11 has markings thereon including vertical or transverse grooves 12 and 13 in spaced apart relation and respectively adjacent to the toe 14 and heel 15 of the head. It is quite usual to connect such vertical or transverse grooves with horizontal or longitudinal grooves extending continuously between the vertical or transverse grooves and so long as these grooves do not exceed a certain depth and are spaced sufliciently from one another, they do not violate the rules at present in force against the use of artificial means designed to impart back spin to the ball.

According to my invention, however, and as most plainly seen in Figure 1 the longitudinal or horizontal grooves 16 extend in alternating relation from the two vertical grooves 12 and 13 and do not extend continuously from one vertical groove to the other. Moreover the grooves 16 according to my present invention overlap one another at their inner ends and are graduated in their overlapping extent, being overlapped to an increasing greater extent from the upper to the lower edge of the blade so as to produce a shaded area readily distinguishable from the remainder of the surface of the blade by virtue of the closer proximity of the over lapping portions of the grooves.

The shaded portion just mentioned marks the place where the ball and the face of the blade should contact as a stroke is made in order to obtain maximum results as far as distance and direction are concerned, and in addition this shaded area also tends to concentrate the mind and sight of the player on that particular part of the face of the blade. This shaded portion moreover will give a player the exact lie and pitch of the club head and will enable him to take a stance conforming as nearly as possible to the proper mechanics of hitting the ball.

Again, on shots where the ball is struck too far out of the face of the blade toward its toe, and where a slice occurs due to the torsional strain on the shaft of the club, the outer edge of the shaded portion of the blade markings will come in contact with the ball, with double the effect of the single lines and will have a tendency to put a strong back spin on the inside of the ball and consequently tend to straighten out the line of flight. This inward spin on the ball will also tend to cause the ball to bound in the opposite direction to its slice in flight and thus when the ball contacts with the ground it will bound in the desired direction rather than follow the undesired slice.

It is for the foregoing reasons that my invention has a fourfold advantage; first, it gives a shaded portion at all times upon the striking face of the blade; second, it concenq trates the mind and sight of the player on the exact point of contact between the ball and the blade; third, it materially benefits the stance of the player; fourth, it tends to a better and truer flight of the ball and to correct instances where the flight is untrue or improper.

While I have shown and described the best mode of arrangement of markings so far devised for the purpose of producing a shaded area at and around the proper striking point, other arrangements of themarkings might be devised and it is to be understood that I claim as my invention all such arrangement falling within the terms of the appended claims.

I claim:

1. A golf club having its blade provided with facial grooves extending toward one another in alternating relation and overlap ping one'another at their, inner portions to provide an area shaded by virtue of the close proximity of the grooves where they overlap. V

2. A golf club having its blade provided with facial grooves extending toward one another in alternating relation and overlapping one another at their inner portions to a gradually increasing extent from the upper to the lower edge of the blade.

' 3. A golf club having its blade provided 7 with spaced apart vertical grooves extending from the upper to the lower edge thereof, and also provided with horizontal grooves extending in alternating relation from the vertical grooves and having their inner portions overlapping.

4. A golf club-having its blade provided with spaced apart vertical grooves extending from the upper to the lower edge thereof, and also provided with horizontal grooves extending in alternating relation fronr the vertical grooves and having their innerportions overlapping to a gradually increasing extent from the upper to the lower edge of the blade.

5. A golf club having its blade provided with facial grooves forming markings and arranged with certain portions in closer proximity than the other portions whereby; to produce a shaded area at and around the first mentioned portions, for the'purpose described.
