TENN IS RAGKET.

Application filed April- 8, 1924. Serial No. 704,951.

To all whom it may concern:

Be it known that I, ALBERT E. THORN LE1, a citizen of the United States, residing at Pawtucket, in the county of Providence hand State of Rhode Island, have invented new and useful Improvements in Tennis Rackets, of which the following is a specification. I M

This invention relates to certain new and useful improvements in tennis rackets. and the primary object of same is to provide a wood racket which is of light weight and which at the same time is of very strong, robust and durable construction.

A further object of the invention is to provide a racket which affords ventilation in the interior or central part of the wood.

" The invention has still further and other objects, which will be later set forth and of themselves manifested in the course of the following description.

In the drawings: I

Figure 1, is a plan View of a racket constructed in accordance with the present invention, the strings being omitted.

Figure 2, is a section on line 22 of Fi ure 1, and 7 iigure 3 is a section on line 3-+-3 of Figure 1. I In roceeding in accordancewith the present invention the bow is made of two ieces or sections 1, 1, the confronting inner aces of which sections are grooved or hol-- I lowed at 2 so as to lighten the structure. If desired a flat reinforcing strip 3 formed of hard rubber or fiber or other suitable com osition may be interposed between the con ronting faces of the wood sections and firmly glued or cemented thereto. Obviously the reinforcing strip may, if desired be omitted and the wood sectlons directly glued 0r cemented together in contact with The usual string receiving I each other.

holes 4 extend transversely through the wood sections and through the reinforcing strip 3 in cases where the latter is employed.

The ends of the sections extend outwardly from the base of the bow and are arranged on opposite sides of the handle filler 5 and wood how, the confronting faces of the throat piece 6 forming sides for the handle.

The hollowed-out parts2 form air-channels that extend throughout the circumference of the bow and also throughout the length of the handle on each side of the latter, consequently air entering the chan-- nels, through the openings 4 and through the ends of the sections at the free end of the handle, maintain the wood in a dry condition. I

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is s 1. A tennis racket having a sectional sections being hollowed out to lighten the weight of the racket and to provide an air circulating channel.

2. A tennis racket having a sectional wood bow, and handle sides formed of continuations of the bow, the confronting faces of the sections being hollowed out to lighten the weight of the racket and to provide an tir-circulating channel.

3.- A tennis racket having a sectional. wood how, the confronting faces of the sections being hollowed out to lighten the weight of the racket and to provide an aircirculating channel, and a fibrous reinforcing strip interpdsed between the confronting faces of the sections and secured to each and extending across the channel. 4.. A tennis racket having a sectional wood bow, the confronting faces of the sections being hollowed out to lighten the weight of the racket and to provide an aircirculating channel and reinforcing means interposed between the confronting faces of the sections.

5. A wood tennis racket having a central channel in the frame thereof to lighten the weight of the latter and to aflord an air circulating channel.

In testimony whereof I have signed my name to this specification in the presence of 95 two subscribing witnesses.
