GOLF

BALL. r

' Specification of Letters-Patent. Patented May 30, 1922.

Application filed October 22, 1920. Serial No. 418,794.

To all whom it may concern:

Be it known that'I, JOHN WHITE, a sub-- ject of the King of England, residing at Sunningdale, Berkshire, England, have in-. vented certain new and useful Improvements in Golf Balls, of which the following is a specification. 1 This invention relates to improvements in golf balls, and has for'one of its objects'to provide a golf ball having a distinctive marking that will not be readily destroyed,- as for example by the blows from a club.

It is well known that the air pockets formed by depressions on the surface of a golf ball materially assist in the fiight of the ball, and it is therefore important that these depressions should remain as clearly marked as possible and free from filling.

With the golf balls at present in use, particularly soft-cored balls, I find that the depressions very soon become damaged by repeated blows from the club, and the life of the balls is consequently very short.

According-to my invention, therefore, I provide la golf ball having a plurality of depressions formed on its surface, and recesses formed in the bottoms ofthese depressions. The depressions and recesses therein may' be of various shapes and proportions but I prefer to make the depressions of rectangular formation and of comparatively shallow depth combined with recesses therein of circular aperture. Y

The secondary recesses are preferably slightly deeper than the outer depressions, and may have a width of approximately one-third of the width thereof.

The invention is illustrated by way of example in the accompanying drawing, in which-- I Figure 1 represents a golf ball, made according to this invention and Figure 2 is a fragmentary sectional view taken through the centre of a' row of de pressions and drawn to a larger scale.

The golf ball has a plurality of-depressions" A formed on its surface, which depressions are preferably of rectangular formation as shown, and arranged so that ribs B are formed betweenthem; Small recesses C of circular aperture are formed in the bottoms of the depressions Aand are protected from the direct blows froma-club by the said ribs B. The sides D of a depression ,preferably slope inwards towardsthe bottom E so that the width of the aperture, at the surface of the ball is greater than the width at the bottom of the depression. The depressions A are comparatively shallow and have fiat bottoms E, and the recesses C therein are preferablyslightly deeper-and have curved bottoms F, as shown in Figure 2. The width of a recess C is approximately one-third of the width across the bottom E of a depression.

I find that of the above proportions give very satisfactory results and also present a striking appearance and my experiments have proved that they possess a much longer life than, fore made, one reason being balls as hereto that the secondary recesses C are not directly affected by the blows from the club, but are'protected to some extent by the ribs B. 7 What I claim as my invention'and desire to secure by Letters Patent is 1.- A golf ball having a plurality of fiat bottomed depressions formed on its outermost surface and having recesses with spherical surfaces formed in the flat bottoms of said depressions, so as to provide intermediate between said surface and lowest point of golf balls having a marking said recesses a surface that is at least approximately parallel face.

2. A golf ball having a plurality of depressions formed on its outermost surface of which depressions the width is greater at the surface of the ball than at the bottom of the depression, and having recesses formed in the bottoms of said depressions, so as to to said outermost surprovide intermediate between said surface and lowest point of said recesses a surface that is at least approximately parallel to said outermost surface.

3. A golf ball having a plurality ofv fiatbottomed depressions formed on its outermost surface and having recesses formed in the fiat bottoms of said depressions the depth of said depressions being not less than one seventh of the width of said depressions at the surface of the ball, substantially as and for the purpose hereinbefore set forth.

4. A golf-ball having a plurality of fiatbottomed depressions formed on its outer- 5 most surface and havingi'ecesses formed in the flat-bottoms of said depressions of a width not greater than one third of the Width at the bottoms of said depressions, substantially as and for the purpose hereinbefore set forth.

In testimony whereof ture.
