GOLF BALL.

Application filed October 5, 1923. Serial No. 666,842.

To all wlw/m t may cof/wem:

Be it known that I, THOMAS W. MILLER, a citizen of the United States, residing at Ashland, county of Ashland, State of 0h10, have invented certain new and useful Im proveniente in Golf Balls, of which the followingis a speoication.

My invention relates to golf balls, and compositions therefor, and is a continuation in part of an a plication for golf ball compositions, filed No. 561,943, and has for its objects, first, economy in the manufacture, at the same time producing a ball which will have to a `very considerable degree all of the desirable qualities of golf balls now on the market,` and, secondly, to eliminate the liability of cutting the ball if topped or struck with the edge of the driving club when in play. l

In. the accompanying drawing:

lIhe figure is an enlarged sectionalview of my improved golrn ball.y

In car ing out my invention, I iirst prepare a, ru ber stock 1 from material suitable to produce a composition of the desired gravity, cutting, as hereinafter set forth. After millingand preparing said stock, it is cut into sections each of substantially the weight of a finished golf ball, and each of said seetions then is placed in registering molds and heated and vulcanized under pressure. Said molds are provided either with projections or de ressions to produce the dimple or bramble e ect as desired, so that the ball 'so compressed and vulcanized as i* 'comes from the mold will have the true exterior design of the finished ball, andalso will have the same diameter less the vthickness of the cover. After vulcanization and removal from said mold any selvage or overflow at the line of mold registration is r noved, and the ball then is cleaned from all undesirable sub stances by boiling in a suitable solution.

The object of applying the dipped cover y me May 18, 1922, Serial density, resiliency and resistance to' 2 is to provide a comparatively hard unyielding surface, the variation of which 4in thickness affects the distance flight of the ball, and also its rebounding properties after striking the ground. A further ob- ]ect is to provide the desired color for the finished ball.

From the above description, it willl,be uner of a thickness which will destroy theA sharp outline of the surfacedesign, the ball after the dipped cover has been applied again can be placedin a mold of a proper size land design, and by applying heat under pressure, the surface design will be brought out more sharply. 4

A. composition which will produce a ball closely approximating the standard ball in its functions embodies the following ingredients and approximate proportions:

Pounds.

Rtubber 32 Glue 18 Zinc, oxide 10% Sulphur It has been found that a, composition of the above formula when vulcanized will resist cutting to a very high degree, and this result is accomplished primarily through the 'use of the rubber and glue ingredients. It

will be understood, however, that I do not limit myself to these proportions, as the glue and rubber' content may be varied somewhat, and certain fillers, such as aluminum liake and asbestos added, with satisfactory results.

Vhile I prefer to form the ball solid, it will be understood that the same may be formed' with a hollow center.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is':- 4.

1.` A golf ball, comprising a homogeneous body portion embodying as a composition,

lis

rubber, glue, a vulcanizing agent, and a filler in such proportions as will approximate the standard ball in size and Weight, saidbody portion being formed and vulcanized to the surface configuration,v of the finished ball,` and a thin cover or finishing coat which conforms to said surface configuration.

2. A golf ball, comprising a homogeneous body portion embodying as a composition,A rubber, glue,f`a vulcanizing agent, and a filler in such proportions as will approximate the standard ball in size and weight, saitl body portion being formed and vul-` canized to the surface configuration of the finished ball,fand a thin dipped cover or finishing coat which conforms to said surface configuration.

3. A golf ball, comprising a homogeneous bod portion embodying as a'composition, rub r, glue, a pv-ulcanizing agent, and a filler in suchproportions as will `approxi` mate the standard ball infsize and Weight, said body portion being formed and vul#y canizecl to the surface configuration of ythe finished bal1,`and a thin dipped cover or finishing coat containing a`-.pig1ne1it fv tion.

LA Vulcanizable composition for golf balls, comprising rubber,

glue, a filler, and a vulcanizin agent, in such proportions as, when forme into a ball substantiall 1.62l in diameter, will Weigh, with the nished coatinglor covering.. approximately 1.62 ounces` 5. A vulcanizable composition for golf balls, comprising rubber, glue, a filler, and a vulcanizing agent, in suchy proportions as, when formed into aball substantially 1.62 in diameter, will weigh, With the finished coating or covering,l approximately 1.62 ounces, and possessing a proper resiliency and a high resistance to cutting.

b'. A vulcanizable Composition-.for golf] rubber approximately 32 balls, comprising parts, glue approximately' 18 parts, zinc oxide approximately 10.5 parts, and sulphur i approximately 2.5 parts.k
