UNITED STATES PATENT OFFICEe HENRY S. CHAPMAN, OF GLENRIDGE, NEWT JERSEY.

PLAYING-BALL.

SPECIFICATION forming part of Letters Patent N o. 711,474, dated October 21, 1902.

Applica-tion filed August '7, 1902.

serial No. 118,780. (No man.)

T0 all whom it may concern:

Be it known that I, HENRY S. CHAPMAN, aY citizen of the United States, residing in Glenridge, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Playing-Balls, of which the following is a specification. Y Y

This invention relates to golf-balls;` and its' object is to improve the construction thereof to the end of rendering the ball more desirable in the game.

In the accompanying drawings, Figure l illustrates, partly in section, the preferred form of ball. Fig. 2 illustrates another form, and Fig. 3 shows still another form.

For the filling of the ball I prefer to use a sphere l, which may consist wholly or mainly of rubber. Upon this filling I prefer to apply a shell consisting of an inner layer or sphere 2 of gutta-percha and an outer adherent or integral sphere or cover 3, consisting of gutta-percha compounded with a 'metallic substance, preferably oxid of zinc, said layers 2 and 3 being preferably put on under heat and pressure and holdingT the rubber sphere 1 under high compression.

The cover 3, Whiclrmay be very thin, is much lighter in color than ordinary guttapercha, by reason of which the ball may be easily found in the grass. The cover has preferably a light grayish tint.' This coinpound of oXid of zinc and guttafpercha makes a shell or cover which is denser and less lively than plain ,frutta-percha and makes the ball more desirable for uttinw While oWin(r to 'its adherence or integrality it is not liable to adhesive quality said layer A acts as a binder between the outer shell B and the inner rubybervsphere 1, said binder adhering on both sides and firmly uniting the cover to the core, While owing to its relative inelasticity it prevents too high an activity of the ball under a light blow. In Fig. 3 I show my improved compound in the form-of a thin shell 3a upon a sphere C of either rubber or solid gutta-percha, Where it has the advantage of furnishing an indestructible lightcolored cover for the ball, while adhering firmly thereto and reducing the resiliency thereof, as explained in connection with Fig. l. If desired, the entire ball may be made of the compoundof gutta-percha and oxid of zinc.

Variations may bevresorted to within the scope of my improvements.

Having described my invention, I claim- 1.' A playing-ball comprising a sphere of elastic material, a sphere ofh guttapercha thereon, and a cover compounded of guttapercha and a metallic substance upon said gutta-percha sphere.`

2. A playing-ball colnprisingla sphere of elastic material, a sphereof gutta-percha thereon, and afcover compounded of guttapercha and oxid of-zinc lupon' said guttapercha sphere.

3. A playing-ball` comprising a sphere of elastic material, a sphere of gutta-percha thereon, and a cover compounded of guttapercha and metal upon said gutta-percha sphere and integral therewith.

4. A playing-ball comprising a sphere of elastic material, a sphere of gutta-percha thereon, and a cover compounded of guttapercha and oxid of zinc upon said guttapercha sphere and integral therewith.

5. In a playing-ball, the combination of a sphere of rubber, a sphere of gatta-percha thereon andI adhering thereto, and a sphere of gutta-percha compounded with oxid of zinc; said gutta-percha sphere being integral. Y

HENRY S. CHAPMAN.
