' TENNIS AND OTHER PLAYING BALL.
Application filed March 31, 1924. Serial No. 703,126.
To all whom it may concern.-
Be it known that we, ROBERT RUSSELL, of Yaldersgate, Beechwood, Heaton Park, Manchester, late of Lands 85 Rhodes, near Manchester, England, a British subject, and HERBERT BROOMFIELD, of 23 Davenport Road, Hazel Grove, Stockport, England, a British'subject, have invented certain new and useful Improvements in or Relating to Tennis and Other Playing Balls, of which the following is a specification.
Hitherto it has been diflicult to retain the air or gas introduced into tennis and other,
playing balls largely owing to the fact that the case is made from rubber mixed with powders or mineral matter and vulcanizing ingredients, which are only partially ground in mixing, and frequently left in minute particles, thus allowing the air or gas to escape when the ball is inflated and used. Further, the heavy cloth used for covering tennis balls and the like absorbs a considerable amount of moisture, during play,
thereby making the ball heavy and generally unsatisfactory.
In the manufacture of tennis and other laying balls the case of the ball is usually made in two sections which may be half so spheres or like the figure 8; in the former case the half spheres are usually pressed together in a mould, while in the latter case they are generally made by hand. Before the sections are combined or fixed together it is ususal to introduce gas, or powder adapted to produce gas and create the internal pressure necessar during vulcanization. A rubber or plastic plug is sometimes provided through which a needle may be 40 passed for the purpose of inflating the ball with air after the sections have been joined together and vulcanized.
The manufacture of tennis and like playing balls according to this invention is not limited to any particular formation regarding the sections, whether made by machine or by hand, but after the sections are cut or moulded, and preferably before vulcanization, they are treated with liquid latex by dipping coating or like operation and are then joined together in the usual way to form the complete ball, which, whencompleted is similarly treated with latex. In
End House,
each instance it is preferable to allow the latex to dry before proceeding with the next operation.
If preferred, the ball may be made in the OF STOGKPORT,
ordinary way and the liquid latex then sprayed into its interior by means of a suitable needle the ball being afterwards placed in. a revolving machine to ensure its interior being thoroughly coated, after which it is placed to dry, the plug downwards so that any surplus latex will settle around the plu After vulcanization and preferably after inflation, the ball, as a whole, is dipped into or coated with latex, one or more times as desired, and afterwards dried, thus forming a film over the compound rubber shell. or casing to prevent the escape of air or gas through said compound shell o r case. or through the aperture in the plug pierced for the purpose of inflation. This further film may be vulcanized or left unvulcanized and used as a solution or medium for the attachment of the outer cloth covering where desired.
In the case of tennis and like playing balls, which are covered with cloth or felt, the cloth' or felt, before being attached to the case or shell, is dipped in latex one or more times as desired, afterwards moulded to the desired shape, dried and then, if preferred, vulcanized by any suitable process to the shell. The vulcanizing agent may be mixed with the latex before application of the various coatings to the sections of the ball,-or to the ball as a whole, orto the cloth.
The latex for the purposes above described may be mixed with other substances such as dyes, pigments, powders, minerals or/and vulcanizing agents, when desirable. For instance in the case of playing balls without the cloth cover where it is desired to produce coloured efiects, patterns or designs on the surface of the ball, or in the case of balls covered with cloth or felt, where it is de sired to produce and retain a white effect, in which case the-surface of the cloth may afterwards be raised to give a nap effect.
It will be understood that whilst preferring to apply the several films of latex be fore named or described, any one may be omitted if desired. It will also be underpreferably with stood that the latex will preferably contain inner film ofvlatex; C is the indiarubber shell of the ball; D is the outer film of latex; and E is the latex-treatedouter cover.
\Ve claim 1. As a new article of manufacture a playing ball composed of sections of vulcanized indiarubber and provided on at least one side with a film of precipitated latex solids.
2. As a new article of manufacture a playing ball composed of sections of vulcanized indiarubber and provided on one side with a film of vulcanized latex.
3. As a new article of manufacture a playing ball composed of sections of vulcanized ind iarubber and provided on both sides with a film of precipitated latex solids.
4. As a new article of manufacture a playing ball composed of sections of vulcanized indiarubber coated on both sides with vulcanized latex.
5. A tennis ball composed of sections of vulcanized ind iarubber covered on at least one side with precipitated latex solids, and of a cloth covering impregnated with precipitated latex solids.
