- Specification'of Letters Patent.

Patented an; 1. 1907.-

. To all whom it may concern: Be it known that I,-EDMUND F. UrToN, a citizen of the United States, residing at 1 Mineral City, in the countyof- Tuscarawas and 5 State of Ohio, have invented certain new and useful Improvements in Hard Rubber-Composition Balls and Processes of Making the Same, and I do declare the following tobe a full, clear, and exact description tures of construction, combination, and ar- 2 rangement of parts, as-will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 isecperspective view showing the manner of tion, showmg the roll of strips-in the dies ready to be pressed. Fig. 3 is a similar view of theball after being pressed, and Fig. 4 is a sectional view of the finished ball.

Referring more particularly .to the drawings, 1 denotes the ball, which is constructed from a strip or series of strips 2 Wound upon themselves to form an elongated roll, the

axis of which is greater than the width of the 4 strip, which ta ers slightly from the center toward its en s, as shown .in Fig. 1 .The

strips-2 are preferably formed of a composition of rubber and other ingredients.

o In forming a ball the strips are preferably rolled by hand into the form hereinbefore described, afterwhich said roll is placed in a two-part mold or die 3, each part of which is preferably hernis 'herical' in shape. After the roll has been t us placed in the dies pressure is applied thereto and the roll'of strips compressed endwise into a solid spherical form, as shown Fig, 3 of the drawings. By

I the in- 10 vention, such as will enable others skilled in ng the strips of which the ball is com- 3o posed. Fi 2 is a side view, partly in secl Application filed May 3,'19 06- SerialNo. 315.089.

armi ball in this manner and subjecting the same to hydrauhc or otherihi' h ressure a compact solid constructionwlll e had, which possess more'or less -resiliency and which will not readily split or chip oii. From the 'fore oing description, taken in connection with t ie-accompanyinp theconstruction andoperation o the invention will be readily understood without re- .quiring a more extended ex lanatlon.

Various changes in the cm, proportion,

drawings, a

and the minor details 'ofcon'structlon'may be resorted to without departing from the prin ciple or sacrificing any of the advantagesof this invention as defined by the appended claims.

Having thus described'my invention, what I claim as new, and desire to secure by Let'-' ters-Patent, is- 1 1. The process of making balls which consists in winding strips ofmaterial diagonally? upon each other, and then ressing said sowound strips intoa spherica body, v 2. The process of making balls which consists in winding strips of elastic material diagonally upon each other, and then pressin said so-woundstrlpsmto a solid spherica 80 body.

3. The process of making balls from sheets or strips of. material, said sheets being first wound into an. oblong body, the axis of which is greater than the width of 'the strip, and

then exerting an endwise pressure on said body-to form it into a,solid, spherical body.

4. The process of making balls of sheets or strips of elastic composition, said strips or sheets being rolled together to form an' elongated body, the axis of which is greaterthan the width 'of the strip and then compressin saidlbody endwise to form it into a soli spherical body.

5. Aball comprising an endwise compressed coil composed of a strip of diagonally-crossed, elastic material- In testimony whereof I have hereunto set .my hand in presence of two subscribing witnesses.

EDMUND r. UPTON.
