Oct. 27, 1925'- H. F. MITZEL GOLF BALL 7 Filed Oct. 6, 1922' Patented Oct. 27, 1925.

UNITED STATES PATENT QFFICE.

HARVEY F. MITZEL, F PROVIDENCE, RHODE ISLAND, ASSIGNOR, BY MESNE ASSIGN-- MENTS, OE ONE-HALF TO THE GOLF BALL CORPORATION OF AMERICA, OF WIL- MINGTOEN, DELAWARE, A CORPORATION OF DELAWARE. V I

com BALI.

Application filed October 6, 1922. Serial No. 592,751.

To all whom it may concern:

Y Be it known that I, HARVEY F. MITZEL, a citizen of the United States, residing at Providence, in the county ofProvldenoe and State of Rhode Island, have invented certain new and useful Improvements in Golf Balls, of which the following is a specification. Y

\ My invention relates to golf balls and has 1 for its essential objects the avoidance of the disadvantages inherent in balls having cores, either solid or soft centered, and in balls characterized by windings of rubber thread under tension or the like; to insure a resiliency equal or superior to a wound ball while possessing a consistency dens ty, or solidity which enables the ball to withstand blows and hard usage without becoming misshapen or nonround, so that a perfeet balance is insured in flight and putting;

to insure a thorough adhesion or amalgamation of the cover and body of the ball;

and to attain these ends in a structure simple in character and facile and inexpensive to construct.

To the above ends essentially my invention consists in such parts and combinations of parts and in such characteristic features as fall within the scope of the appended claims. v

In the accompanying drawings which form a part ofthis specification,

Figure 1 is a side elevation of a golf ball embodying my invention.

Figure 2 is a detail view of the disassembled constituent original parts of the same,

and

Figure 3, a section on line of Fig-' ure'l.

Like reference characters indicate like parts throughout the views.

My ball comprises a spherical body 4.- of vulcanized material possessing a great degree or hardness combined with a measurev of resiliency, such as 1S afforded by a vul-" canizedj combination of balata and rubber. The surface is roughened bycorr'ugations 5 or otherwise. A cover for the body is provided cdiiiprising hemispherical sections '1 I interengaged depressions of balata of dimensions such as to completely cover the body when moulded thereon. In Figure 2' the sections are shownsubstantially as they appear prior to the moulding operation. After'the moulding operation the edges 8 of the shell are in such intimatecontact with each other as to be practically invisible, and the sections constitute a practically continuous shell 9 of a stifi anchtough character. The corrugations or rough elements 5 which are impressed into -the sections during the moulding operation assist in preventing any relative movement of the cover and shell during use. In the drawings 11 indicate the resultant depressions in the shell sections formed by the corrugations and in which the corrugations register.

It will be understood that the depressions 11 are not present'in the sections.

prior to moulding.

In this instance the cover. has formed in its exterior the usual semispherical depressions 13.

1. A golf "ball composed solely of a vulcanized spherical centre and an outer shell covering of balata, the two being permanently united by a mulitiplicity of 'interengaged integralportions thereof whereby the two are rendered relatively-non-movable in golf ball fozmed of an unwound,

permanently united by-heat, with portions of the s'hellcovering and body provided with and protuberances.

A golf ball' composed of a vulcanized centre and'a balata shell covering, the latter being in sections joined to each other and to the centre by heat, the centre and shell covering having depressions and protuberances interengaged by the application of the shell covering, whereby the latter is immovably united to the centre. i

In testimony whereof I have afiixed my.

signature.

HARVEY F. MITZEL.
