GO LF-BALL.

SPECIFICATION forming part of Letters Patent 0. 698,402; dated April 22, 1902.

Application filed March 31, 1902- Serial No. 100,721. (No model.)

To all whom it may concern:

Be it known that I, ELEAZER KEMPSHALL,

a citizen of the United States, residing in BUS.

to form a core, which has been inclosed in a shell of gutta-percha; but when the shellis out through by an implement and some of the rubber threads are out they quickly unravel, with the result that the Wound portion of the ball flies to pieces or becomes so badly deranged as to be useless. My invention minimizes or overcomes this difficulty, while preserving all of the advantages of the wound rubber-thread ball. I

In the accompanying drawings, Figure l is a View, partly in section, of a ball made in accordance with my improvements. Fig. 2

stage in the manufacture of the ball.

In the several views similar parts are designated by similar characters of reference.

I preferably employ a springy center piece A, which may be rubber or gutta-perc'ha, preferably the latter, and which is preferably somewhat less than one-half the diameter of the completed ball. Upon this center piece I wind a rubber band or bands 13, layer over layer, under great tension, so as to form a core O, and upon this coreI weld hemispherical segments D and E of plastic material, such as celluloid or gutta-percha, preferably the latter,.said segments being preferably lined with fabric F and the welding being effected by heating and compressing between dies G and H, although the shell maybe otherwise formed. The fabric may be omitted, if desired, although I prefer to use it because it reduces the liveliness of the ball when given Fig. 3 is a view of my improved core, and Fig. 4 illustrates the final a light blow in putting. The wide bands B being under tension fit down snugly facewise upon the ball. Moreover when the shell is cut through by an implement the likelihood of one of the wide bands being entirely severed is minimized or eliminated, and hence of this condensation the efliciency of the ball asawhole is enhanced. A core made after the manner of my invention packs much closer than a core made of rubber threads, and hence is foundin practice to be much more desirable,especially when held under compression by a" plastic shell. By'employing the fabric lining F the ball is rendered less lively when given a light 'blow,'while the shell is strengthened and there is less liability of an implement cutting through to the rubber'core.

Various shells and center pieces may be used, and other variations may be resorted to within the scope of my improvements.

Having described my invention, I claim 1. A playing-ball comprising a core which consists mainly of wide, solid rubber bands Wound facewise under tension, and a shell of plastic material upon said core, said shell being-lined with fabric.

2. A playing-ball comprising a core which consists mainly of wide, solid rubber bands wound facewise under tension, and a gutta= o percha shell upon said core, said shell being lined with fabric.

3. In a playing-ball, the combination of a center piece; wide solid rubber bands wound facewise thereon to form the main part of a core, and a gutta-percha shell holding said core under compression.

4. In a playing-ball, the combination of a center piece; wide solid rubber bands wound wise under high tension, and said shell befacewise thereon to form the main part of a ing formed of plastic material lined with 10 core, and a gutta-percha shell compressed fabric and confining said core in reduced upon said core and provided with a fabric bulk. lining.

5. A playing-ball comprising a core and a I Witnesses: shell; the said core being formed mainly of B. O. STIOKNEY, wide, solid, thin rubber bands wound face- 1 JOHN O. SEIFERT.
