FRANCIS H. RICHARDS, OF HARTFORD, CONNECTICUT, ASSIGNOR TO THE KEMPSI'IALL MANUFACTURING COMPANY, OF ARLINGTON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

Application filed October 1, 1902.
To aZZ whom it may concern:
Be it known that I, FRANCIS H. RICHARDS, a citizen of the United States, residing at Hartford, in the county of Hartford and State of 1 Connecticut, have invented certain new and useful Improvements in Playing-Balls, of which the following is a specification.
This invention, relating to playing-balls, and especially to those adapted for the purposes of golf, has for its object to provide a structure whereby increased efficiency is obtained at a reduced cost of manufacture.
In the drawings forming part of this specification, Figure 1 illustrates a ball partially broken away to show its components. Fig. 2 shows a strip of stock from which a spring is shaped or bowed, and Fig. 3 illustrates the method of building up the interior of the ball.
In the various figures like parts are designated by similar characters of reference.
The interior of the ball, as shown, preferably comprises a hard center piece A, which may be formed either of a solid body of pla'stic or fibrous material or it may compriseafl metal or steel shell. This central body A is inclosed in a shell of suitable material 13- such, for instance, as celluloid. This part of the ball may be formed, if desired, in the manner illustrated in the patent granted to me October 14, 1902, No. 711,228. Upon the structure thus formed I build up a layer C of high resilience, preferably, as shown, by winding on the center piece A strips Z, Fig. 3, of either sulfur-cured rubber or acid-cured dental dam, the latter being preferred principally because it is acid-cured and practically free from foreign mixture, which would impair its elasticity, and also because it can be drawn taut without liability to rupture and is not liable to become out. I preferably employ this material from one-half to three- "ball under high compression.
- from one-fourth to one-half of an inch, as at Serial no. 125,523. (No model.)
.2, Fig. 3, and its thinness in due proportion. A further advantage of the dental dam is its lightness, whereby the weight of other'parts tune ball may be to some extent compen- 5o sated. Simultaneously with winding the rubber strips I insert in miscellaneous directions short lengths of tern pered-steel wire,which are preferably flat or oblong in cross-section, as illustrated, and which are bent or curved to form springs D, and these are placed flatwise upon the ball during the winding operation. These springs D are formed unto varioussized hemispherioally-curved members and are of such sizes as to permit them to be sprung onto the spherical structure F at each winding, (see Fig. 3,) thereby makinga tension in the wire, whereby each member tends constantly to recover its normal condition, so that every member is in a state of high initial tension. Moreover, since the rubber is wound-upon the ball under great tension it holds the inclosed central portion of the The structure hence comprises a sphere which is bound 7o tightly within windings of highly-tensioned sheet-rubber holding under tension a plurality of individual springs, said springs being highlytensioned by the bending, so that a ball of phenomenal energy is produced. The relative'arrangement shown and described is not essential in all cases, so long as windings of rubber alternate with the insertion of springs, as'variations in windings of wire and rubber maybe resorted to. It will be seen that thew'ire springs are of diiferent diameters and inserted in difierent directions and also that each spring is bound tightly by the highly tensioned rubber, whereby the spring action is considerably modified, the same being rendered far more resisting than would be the caseif. the spring were not restrained by the rubber. The effect of overwinding a spring in this manner is to render it extremely stiff, so that a light 0 blow from a club upon a ball fails to flex the wire to such an extent as to render the ball unduly active. The outer layer of windings of rubber confining a series of distorted springs holds all within a powerful grip, so that the tendency upon the part of all of the members is to preserve a spherical form. When the ball is given a hard blow with a club, the springs directly affected by the club are flexed, while the ball as a whole is changed from its spherical form, this change beinginstantly resisted by the springy spherical core F, which is confined under great tension by the windings of rubber and said springs, so that the ball has phenomenal flying power. It will also be seen that each spring is packed or embedded within the rubber, so as to form a perfectly-acting resilient member which can Withstand considerable deformation under a blow and recover its form completely and instantly. Upon the filling thus formed I provide a shell 5, of wear resisting material, preferably guttapercha, and preferably holding said filling under a high degree of compression. Since the springs and rubber are very effective in maintaining the spherical form of the filling, the shell, although in a tense condition thereon, is not subjected to undue additional strain by reason of the change of the filling from its normal spherical form under a blow, so that liability of the shell to burst under a heavy blow is minimized. It will also be understood that the layer, which is formed of springs and windings of rubber and which is designated as O, furnishes a peculiar local resiliency under the action of a blow and makes a very effective distribution of the force of the blow throughout a large portion of the ball.
Having thus described my invention, I claim 1. In a playing-ball, the combination with a core, of windings thereon of tensioned rubber alternating with bowed individual members of resilient material, and a cover upon said windings. I 2.
