The degree of tension may be regulated by maintaining the con core. Second, to provide a method oi producing golf trol of temperature for a predetermined time and ball cores containing a gas developed within the then sterilizing as by pasteurization, or by using a measured quantity of fermentable material. . Third, to provide a method of producing highly The culture may be allowed to die from products of its own metabolism in a- balance culture tensioned golf balls. 10 Fourth, to provide an improved golf ball which medium. 10 By this method a very substantial pressure is well balanced and capable of long and accurate within the core may be produced, depending ?ight.

Inasmuch as the cores, ?lled with inoculated my invention will de?nitely appear from the de scription to follow. The invention is de?ned in material, may be wound completely before gas formation is permitted, it is possible to produce the claims.

' ' Referring‘to the drawing, the numeral 5 ‘indi 35 cates a golf ball generally, which comprises a core 40 stretching tension. This method of winding may be that commonly employed in the manufacture of golf balls. ' I provide a high elastic tension within the core by introducing therein, before winding, a mate ticed.

The culture medium is of such a composition that the formed gas 55 determines the distance over which a golf ball can be driveni controllable by temperature but golf balls may be manufactured by this method under favorable factory conditions; for example, the winding operations can be performed at more comfortable temperatures than are practical with certain methods of manufacturing golf balls now prac Fig. 6 is an elevation of the core, the expansion 45 ' a golf ball becomes an important factor in the elastic tension of the ball as a whole, this factor will remain evenly distributed throughout either ‘I have not attempted to point out all the modi claim as new and desire to secure by Letters Patent is: 1.
