TENNIS BACKET AND THE LIKE
William B. F. Hall, Fort Wayne, Ind.
Application June 22, 1936, Serial No. 86,471
8 Claims. (01. 273-75)
For purposes of speci?c illustration and notby
This invention relates to improvements in ten
way of limitation, a tennis racket has been shown
nis, squash, badminton, ping pong and like rack
ets, and it consists of the matters hereinafter de
scribed and more particularly set forth in the ap
5 pended claims.
Games in which rackets of the types men
tioned are used require such strenuous activity
that the player usually perspires freely. Such
perspiration is particularly objectionable in the
10 racket-holding hand. It not only affects the
grip but also makes the hand uncomfortable
which adversely a?ects play.
One of the objects of the invention is to provide
a racket with a novel handle structure wherein
15 the grip portion is ventilated to cool the hand
and thus enable better gripping of the handle
and to keep the latter in a drier condition.
Another object of the invention is 'to provide a
racket so constructed that when it is swung in
one direction in a plane at a right angle to the
20 face of the string frame, air enters the handle
from the throat end and discharges out through
the grip portion and when swung in the other
direction in said plane, air is drawn into the
handle through the grip portion and discharged
25 out through the throat end of the handle, to keep
both the hand and the grip portion of the handle
in a relatively cool, dry and non-slippery condi
tion.
A further object of the invention is to provide
a racket with a handle having a non-slip and
ventilated grip portion, which does not increase
the weight, nor impair the strength of the racket.
Still another object of the invention is to pro
vide a racket with a handle having a positive
ventilated grip portion which is practicable to
produce under modern methods and which does
not add unusual weight, appearance or feel or
adversely affect balance.
- The above mentioned objects of the invention,
40 as well as others, together with the several ad
vantages thereof, will more fully appear as the
speci?cation proceeds.

Referring now in detail to that embodiment of
the invention illustrated in the drawing:
5 indicates the string frame of the racket and
6 indicates the handle thereof ‘which joins the
frame by means of a throat portion .1. The
frame and handle as well as the throat may be
made of any suitable material and as herein 10'
shown are-made of Wood.
At the free end of
the handle, there is an annular shoulder 8 for
engagement by the heel of they hand for the
purpose well known.
The handle may be of any desired cross sec
and which is the part gripped by the hand in
play, I herein term the “grip” portion of the
handle. In this grip portion are formed longi
tudinally extending and preferably square cut
grooves I8 which open through the free end of
the handle under the shoulder 8. As shown
herein, there are two of such grooves 'in'each
face and one of such grooves in each bevelled
corner. Holes 19 are formed in the grip portion
and these holes all open at one end into the pas- .
sage l4 and open at the other end into an asso
ciated groove.
In the use of the racket, the player’s hand grips
the grip portion in the usual manner. ‘Due to the
presence of the grooves I8, a ‘good grip is had
upon said portion. The racket cannot accidently
turn in the hand either in making a fore-handor
a back-hand swing.
In making a swing or stroke with the opening
l6 facing in the direction of the swing or stroke,
atmospheric air is forced into the passage 14
the line 3—3 of Fig. 2, and
Fig. 4 is a transverse detail sectional view
through the hand grip- portion of the handle as
taken on the line 4—4 of Fig. 2.

tional shape and as herein shown, is substan
tially rectangular having the front and rear faces
9 and’ i8, side faces I! and I2 and bevelled cor
ners l3. In this instance, by the term “front and
rear faces” is meant those faces arranged paral
lel the playing surfaces of the string frame.
Preferably, axially in the handle is a longi
tudinally extending passage [4f This passage
which may be formed by boring into the handle
from its free end, is closed at said end by a plug
I5. The other end of said passage extends sub
stantially into the throat portion 1 where it com
municates with an outwardly ?aring opening 16

from the throat end thereof and is discharged
outwardly through the openings I9 into the
grooves IS. The air evaporates the perspiration
on the playing hand and not only dries the grip 55

portion but also cools the hand. Thus, both the
grip portion and the playing hand are main
of .the handle, the handle having a hand grip
tained in a good playing condition. In a back
hand swing or stroke, the opening IS in the
throat faces in a direction opposite the direc
tion of the swing or stroke. This produces a sub
atmospheric pressure about the back of the
passageway having an opening to atmosphere at
throat in the vicinity in which the opening 16
is located. Thus air enters the grooves l8 to pass
10 under the enveloping part of the hand gripping
the grip portion and then passes through the
holes l9 into the passage [4 and out of the open
ing l6. Thus a breathing action occurs through
the handle and grip portion in accordance with
15 the swings or strokes made.
The grip portion as well as the hand, remains
substantially dry and this in connection with the
grooves l8 eliminate possibility of the handle
turning axially in or slipping endwise of the hand
20 during play. The grip portion of the handle not
only provides that“feel”inthe player’s handwhich
is conducive to good playing of the game, but it
is also of such construction that it can be readily
manufactured.
