PATENT OFFICE.
GEORGE PAUL SCHILZ, OF BROOKLYN, NEW YORK.
TENNIS- acker STRING.
Application filed October 6, 1926. Serial No. 139,948.
The invention aims to providea stringing for tennis racket-s which will be livelier and more resilient than the gut which is in general use for such purposes; Further objects and advantages of the invention will be in part obvious and in part specifically pointed out in the description hereinafter contained which, taken in connection with the accom panyingdrawings, discloses a preferred ein- Such embodiment, however, is to be considered as merely illustrative of its principles. In the drawlhe single figure is a side view, partly broken away of a string constructed in accordance with the invention.
In accordance with the present invention, I employ in connection with gut strands as customarily used for stringing tennis rackets, one or more strands of rubber or the like, the gut being twisted in the usual way 7 whereby when the string is tensioned in the racket frame, the rubber strand will afliord increased resiliency lengthwise of the strings and will also atiord greater elasticity transversely of the. strings. due to the fact that the gut strands will act to compress the rubber strand.
I prefer to use a rubber strand in the form of a core about which the gut strands are wound spirally so as to enclosethe core and protect it against wear. In the illustrated embodiment of the invention there is shown a string having a rubber core 1 surrounded by the spirally wound gut strands 2, the gut strands being wound around the core 1 with such tightness as to hold the core under a certain amount of initial compres sion which is augmented when the string is tensioned.
The gut employed may be animal or vegetable in its nature, or a combination of both types, no particular gut being essential.
I claim:
1. A string'for tennis rackets and like purposes, having gut strands and a strand of rubber-like material combined therewith.
2. A string for tennis rackets and like I purposes, having a core of rubber-like ma terial with gut strands wound spirally around the same.
'3, A string for tennis rackets and like GEORGE PAUL SCHILZ.
