PATENT OFFICE.

ALLEN H. BE R, or BROOKLYN, NEW YORK.

TENNIS RACKET.

Application filed December 6, 1924. Serial No. 754,243.

1 '0 all whom it may concern:

Be it known that I, ALLEN H. BEHR, a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Tennis Rackets, of which the following is a specification suflicient to enable those skilled in the art to which the invention appertains to utilize the same.

My improvements relate to formation of rackets, so called, used in the game of tennis; and more particularly to the cords used in the formation of the net work thereof, and are designed to afford an intersticed woven contactual impact surface of superior elasticity and resilience, of exceptional strength and durability, and which is not affected by moisture or change in atmospheric conditions, all as hereinafter fully set forth, the invention consisting in the specific construction, combination and arrangement of component parts described and claimed, and the distinctive feature being the use of a gut core strand covered with a textile weave and protected externally by a coating of waterproof varnish.

In the accompanying drawings I illustrate a practical embodiment of the essential features of my invention, although I do not restrict myself to the identical form and construction of parts shown herein by way of exemplification, since modifications in minor detalls, and equivalent mechanical expedionts may be resorted to with like results, and without departing from the spirit and intent of my invention in this respect.

With this understanding Fig. 1, is a perspective view of a tennis racket made in accordance with my invention;

Fig. 2, a detail view on an enlarged scale illustrating the construction of the impact cord; and

Fig. 3, is a transverse section taken upon plane of line 33, Fig. 2.

The racket frame F, and its handle F, are of ordinary construction, the frame F,

being formed with the usual perforations.

f, f, for the threading and support of the cord C, constituting the impact medium for contacting with a tennis ball.

Said impact cord consists of a central strand or core 0, of gut such as heretofore used for the formation of the mesh of a racket, around which is woven a covering 0 of silk thread or equivalent textile material, the latter being in turn covered and surfaced with a coating of waterproof varnish 0 as indicated more particularly in Figs. 2 and 3, of the drawing.

By this construction of impact cord C, the usual gut 0, is reinforced and strengthened by the Woven covering 0 without impairing its flexibility, while the outer casing of varnish renders the whole impervious to moisture, so that a relatively strong, tenacious, elastic resilient impact surface may be woven upon and within the frame F, not subject to deterioration by reason of changes in atmospheric conditions, and of relatively long life and utility.

The silk or other textile fabric, covering and in direct contact with the gut core, acts as an absorbent medium and binder for the external coating of waterproof varnish,thereby efiectually protecting the cord in a unitary sense, and maintaining and prolongingits efficiency.

In certain cases it may be desirable to weave the silk-covered gut on the racket frame before the waterproof varnish is apcation of the waterproof varnish to the cord thus in position as when applied to the fabric covered gut in a preliminary stage. I do not however limit myself to the use of a waterproof varnish in this connection, since any varnish will act as a protectivc medium.

What I claim as my invention and desire to secure by Letters Patent, is

1. A tennis racket having an impact medium consisting of a weave of cord comprising a core of gut, enclosed in a textile covering coated with waterproof varnish, substantially in the manner and for the purpose set forth.

2. An impact medium for tennis rackets comprising a core of gut, enclosed in a textile covering coated with waterproof varnish, substantially in the manner and for the purpose set forth.

3. A tennis racket having an impact medium consisting of a weave of cord comprising a core of gut, enclosed in silk and covered with Waterproof varnish, substanpurpose loo comprising a core of gut enclosed in a Weave of silk, substantially in the manner and for the purpose set forth.

5. An impact medium for tennis rackets v comprising a core of gut enclosed ina WQELVG of textile fabric, substantially in the manner and for tllBPUlPOSG set forth.

6. An impact medium for tennis rackets pose set forth.
