GOLF-BALL.

SPECIFICATION forming part of Letters Patent No. 716,291, dated December 16, 1902.

Application filed Tune 17, 1902- Serial No. 112,108. (No model.)

To atZZ whom it may concern:

Be it known that I, EMMET SCHULTZ, a citizen of the United States, residing in Arlington, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Golf-Balls, of which the following is a specification.

This invention relates to playing-balls, especially those used in the game of golf; and its object is to reduce expense of makingthe ball,while increasing the efficiency and dura bility thereof.

The accompanying drawing shows, partly in section, a golf-ball made in accordance with my improvements.

. ispheres of plastic material, preferably celluloid, to form a shell 3, said shell holding the core in a state of high compression. One important advantage of my improvement resides in the stability of the core at the operation of compressing the shell upon the ball, since the core is not affected by heat incident to the welding operation, and hence the centerpiece is not liable to soften and change L its shape or get out of center under the great pressure to which the ball is subjected at this operation. Whencelluloid is used for the shell, it becomes incorporated with the celluloid or pyroxylin B in the core, thus minimizing the liability of separation of the shell fromthe core. The described core forms in practice an excellent backing for the celluloid, minimizing the liability of the latter to crack and renderingthe ball efficient in driving and putting.

In forming the core the compressible cork and celluloid mixture is preferably hardened under great pressure, so thatitis of smaller bulk than if the pressure were not applied,

and it will be understood that at the operation of welding or forming the shell upon the ball the core is again subjected to great pressure, which is maintained while the entire ball hardens, so that the cork and the celluloid, collodion, or pyroxylin with which it is mixed are permanently retained under compression, and the mass therefore has a tendency to expand the shell, and hence to preserve the spherical form thereof and aid the latter in promptly recovering its form when distorted by a blow, thereby increasing the liveliness of the ball. The resistance of the cork to further pressure is, however, so great as not to be unduly affected by alight blow,

and hence the ball is found to be excellent for putting. It will be further understood that the pyroxylin exists in the core in the form of a continuous irregular honeycomb or agglomeration of cells, and is hence quite stiff and resisting, especially since itis backed by the particles of compressed cork, and conduces to the playing qualities of the ball, and since the shell is formed of the same or kindred material and becomes incorporated therewith at the union of the core and the shell it is seen that a ball of unusual solidity and effectiveness is produced. Any shock received by the ball is transmitted by the hard pyroxylin to the cork, which being in a state of high compression is effective to cushion the bloW and by its reaction to aid the flight of the ball.

In using the term cork or granulated cork I mean to include all substitutes therefor-such, for instance, as sawdust-Arr several comminuted substances may be incorporated with the pyroxylin. Cork and rubber or cork, rubber, and sawdust may be used or any other mixture of light material. In some cases I have used with good results fifty per cent., by weight, of cork and fifty per cent. of celluloid in plastic condition.

Having described my invention, I claim- 1. A playing-ball comprising a spherical core of granulated cork incorporated with pyroxylin, and a shell of celluloid incorporated with said core. 1

2. A-playing-ball comprising a spherical core of granulated cork incorporated with pyroxylin, and a shell of celluloid incorporated with said core, and holding the same under compression.

3. In a playing-ball, a hard sphere consisting of granulated cork incorporated with pyroxylin and in a state of high compression.

4. In a playing-ball the combination of a sphere consisting of granulated cork incorporated with pyroxylin and in a state of high compression, and a hard cover.

5. In a playing-ball, the combination of a core consisting of granulated cork incorporated with pyroxylin and in a state of high compression, and a hard shell of plastic material upon said core.

6. In a playing-ball, a hard sphere consisting of elastic comminuted material in a state of compression and incorporated with pyroxylin.

7. A playing-ball comprising a spherical core of granulated cork incorporated with pyroxylin and in a state of high compression, and a shell of celluloid upon said core.

8. A playing-ball comprising a spherical core of granulated cork incorporated with pyroxylin and highly compressed, and a shell of celluloid incorporated with said core.

9. A playing-ball comprising a spherical core of granulated cork incorporated with pyroxylin and highly compressed, and a shell of celluloid incorporated with said core, and holding the same under compression.

10. A playing-ball comprising a shell of plastic material and a sphere within and joined to said shell; said inner sphere consisting of comminuted material mixed with plastic material which is similar in composition to the material of said shell.

11. A playing-ball comprising a shell, and pyroxylin united to and existing within the shell in the form of a continuous irregular honeycomb which is stiff and resisting, said shell consisting of kindred material.

12. A playing-ball comprising a shell, and springy plastic material incorporated with and existing Within the shell in the form of a continuous irregular honeycomb which is stiff and resisting, said shell being formed of celluloid'.
