GOLF BALL Filed June 8, 1931 INVENTOR Leona/"0 1% Your? ATTORNEYS Patented Sept. 22 1936 @UNITED(STATES PATENT OFFlflEiJ; flaosa'szef, p GOLFBAVLL U Leonard Young, lletroit, I Application June "8, 1931 Serial No.,5 42,848 1 scams. (01.273-62l.

The'main objects of this inventionare:

;-First, to provide a golf ball having along true ar y 7 Second, to provide a golf ball having the above mentioned advantage which has a soft feel of the club.

Third, to provide a golf ball having an even roll in putting.

Fourth, to provide a method of making golf balls and cores therefor by means of which the results above set forth may be obtained.

Objects pertaining to details and economies of my invention will defim'tely appear from the description to follow. The invention is defined in the claims.

A structure embodying the features of my invention and made by the method is clearly illustrated in the accompanying drawing, in which:

Fig. 1 is a fragmentary section of a golf ball embodying the features of my invention, no attempt being made to show the parts in exact dimensions and certain parts being shown conventionally.

Fig. 2 is an enlarged fragmentary section showing further details of the structure.

Fig. 3 is a fragmentary section illustrating one of the steps in the manufacture of the winding core of my improved golf ball.

Fig. 4 is a fragmentary section of one of the sections used in forming the winding core.

Referring to the drawing, my improved golf ball comprises a winding core designated generally by the numeral l, a winding 2 of resilient strands and an outer casing 3. The winding and the casing are shown conventionally. The elastic strands are wound upon the core under very considerable tension but this step is well understood in the art. The casing or outer shell is also shown conventionally as the methods and means now in use may be employed for applying this outer casing.

My improved winding core comprises a spherical center weight 4 of metal such as lead, steel, copper, or some composition which has the desired specific gravity, and it is also contemplated that it shall be substantially unyielding. This centerweight is disposed. centrally of a winding core shell or winding core proper 5 which is formed of rubber and has walls of suficient thickness to 50 sustain the pressure of a gaseous fluid within the same. This core wall 5 is a true sphere and is of an internal diameter substantially greater than the center weight, providing a space 6 for the gaseous fluid under pressure.

55 To maintain the center weight in a central position' the core 5 is provided with internalweb-lik spacing members I preferably'integr'al with the core. The shell has a thin-sheath of rubber 8 thereon to' which the spacing members! are joined by vulcanizing or curing step. 5

In manufacture the sections 9 are molded preferably in hemispheric form. These are placed within a curing mold, the sections of which are indicated at' I0 and H, Fig. 3, the center weight with its rubber sheath having been placed within 10 the shell. The curing mold is then closed and the curing operation performed which unites the sections, forming in effect an integral winding core. The means for introducing the air or other gaseous fluid under pressure is not illusl6 trated.

The gaseous fluid may be introduced by means of a needle-like nozzle which is withdrawn as the curing mold is closed. Another means of obtaining the fluid pressure is to place within the core 20 a material which is gasified by the vulcanizing or curing heat.

In the further steps of manufacture this core is frozen to render non-yielding and is then wound with the elastic strands under pressure, and the 25 casing is applied. The two latter steps may be performed in accordance with present practice.

My improved golf ball is very responsive and has a long true carry. It is also very desirable for putting and has the soft feel which is 30 sought for in golf balls. While it is recognized that the entire weight of the ball shall not exceed the standard or determined amount, the applicant by this arrangement is able to provide,

a distinct center of gravity and at the same time 35 have an air or gaseous cushion so that the ball is very responsive and at the same time true in its action.

Having thus described my invention what I claim as new and desire to secure by Letters Pat- 40 en 15:

1. A golf ball comprising a spherical center weight of metal, a thin encasing sheath of rubber on said center weight, a winding core shell consisting of a pair of complemental hemispherical 5 sections having internal web-like inwardly tapered ribs extending longitudinally between common poles of the sections and fitting said sheath to center said weight within the core and dividing the space between the shell and sheath into a plurality of individual longitudinal cells for the reception of gaseous fluid under pressure, the parts being vulcanized to form an integral whole and to render said cells individually fluid-tight, and a winding of resilient rubber strands on said V 7 common poles of the sections and fitting said sheath to center said weight within the core and dividing the-space between the shell and'sheath into a plurality of individual longitudinal cells for the reception of gaseous fluid under pressure,

the parts being vulcanized to form an integralwhole and to render said cells individually fluidtight. H

3. A golf ball comprising .aspherical center weight, a thin encasing sheath of rubber on' said center weight, and a core shell' having-internal .web-like, inwardly-tapered ribs extending longil tudinallyfbetween common poles 'of the sections 7 and united'with said sheath to centersaid weight within the core and dividing the space between the shell and sheath into a plurality of individual fluid-tight longitudinal cells for the reception of gaseous fluid under pressure.

4. In a golf ball, a spherical center weight of metal, means surrounding and centering said weight comprising a rubber sheath and a winding core shell having internal web-like longitudinal inwardly tapered ribs, said ribs being integrally joined to said sheath at their inner ends "whereby a plurality of individual fluid-tight cells are formed, a gaseous fluid under pressure in said cells, and a winding of resilient strands on said core shell.

5. In a golf ball, a spherical center weight,

means surrounding and centering said weight comprising asheath and a winding core shell having internal web-like longitudinal ribs, said ribs being integrally joined to said sheath at their inner ends whereby a plurality of individual fluidtight cells are formed, and a gaseous fluid under pressure in said cells.
