INFLATABLE BALL
Edward B. Peters, Chicago, Ill., assigner to
Standard Sports Mfg. Co., Chicago, Ill., a cor
poration of Illinois
Application March 20, 1935, Serial No. 11,925
8 Claims. (Cl. 273-65)
The invention relates generally to inflatable
balls and more particularly to a ball comprising
a cover or casing enclosing a bladder, such as a
football, basketball, or the like.
In a ball of this character, the cover is usually
made of sections of leather or the like shaped so
that, when the edges of the segments are sewn to
gether, the spherical or ovoid shape of the ball
is attained.
Usually a part of one seam is left
unsewn to provide an opening for the insertion
1 c, and withdrawal of the bladder, a means such as
a lacing being provided to close the opening after
the bladder is inserted. At one time in the de
velopment of such balls, the bladder', which was
usually made of rubber, was provided with a pro«
truding tubular stem of the same material posi~
tioned at the laced opening for inflation of the
ball. In a later form of ball, the cover or casing
was provided with a smaller opening spaced from
the bladder insertion opening, and the bladder
“O was detachably attached to the cover at that
point with a valve embodied in the attaching
means so that the bladder could be inflated or
deflated through the smaller opening. This con
struction thus permitted lacing up the bladder
insertion opening before the ball was inflated, or
as in some constructions, permitted a form of
lacing or the like for the bladder insertion open~
a valve structure adapted to be secured to the
cover at a seam in such a manner that the means
for so securing the valve structure occupies but
'ttle space within the cover and hence does not
unduly distort the bladder.
It is also an object to provide a ball of the 5
foregoing character inwhich the inflationopening
and the related valve structure are placed at the
seam diametrically opposite the one having the
bladder insertion opening in order to counterbal
ance the `weight of the lacing kor closure means.
Another object resides in providing a ball in
which the valve structure is secured to the cover
at a point spaced from the bladder insertion
opening in such a manner that it leaves the lin
ing free of any attachment to the cover proper
except at the seams where the lining is normally
attached.
,
A still further object is to provide an inñatable
ball in which the valve structure is attached to
0
the cover by stitching but in such a manner that
no stitching appears on the outer surface of the
ball.
Other objects and advantages will become ap
parent from the following description taken in N) OI
connection with the accompanying drawing, in
which:

._ .i This was done to avoid difficulties arising because
"'J of the thick inturned edges of the seam joining
two sections. But, in a ball having a cover com
prising an even number of sections, as in the case
of a football, the ball was thrown out of balance
by so placing the inflation opening and the valve
structure cooperating therewith, since the weight
of the valve structure was not opposite that of
the lacing. Moreover, in balls employing a fabric
lining inside of a leather cover, as in the case of
r the better grades of footballs, _it was found that,
by securing the valve structure to the lining and
leather of the cover, the lining was thus secured
to the leather intermediate the seams and was
caused to rip because of the difference in stretch
between the fabric and the lining, when the ball
received a blow suñìcient to cause some distortion
thereof.
The general object of the invention is there

The preferred embodiment of the invention
comprises generally a cover made of a plurality
of sections sewn together at their edges. Within 45
the cover is a bladder, and to provide an opening
for its insertion into the cover, a portion of one
seam in the cover is left unsewn with means for
closing this opening when the bla-dder is in
flated. A valve structure for the bladder is pro Ul O
vided with means for securing it to the cover at
a point spaced from the bladder insertion open

was that by securing the valve structure to the

such an arrangement tended to throw the ball off
cover at such a point, the lining also was neces
sarily secured to the cover proper at this point.
This produced an undue stress on the lining when
the ball was distorted by a blow, which often ,
caused the lining to rip.
Balls of this type often are provided with a

15 of the cover and lining between the seams rela
tively free. rI‘hus, when the ball receives a blow
sufñcient to distort it, the cover proper and
lining may each stretch or yield to the extent
permitted by the material thereof. By placing
20 the valve structure at the seam, the relative yield
ing of the lining and cover proper is retained, the
securing means for the valve structure being
stitched to the cover only at the seam. More
over, as shown in the preferred form of construc
25 tion, the stitching from said securing means may
extend through the inturned edges of the cover
sections so that it does not appear on the out
side of the ball. It thus avoids undue wear.
As shown in the drawing, the preferred em
30 bodiment of the invention comprises a cover made
of a plurality of sections lll. Each section is so
shaped that, when it is joined at its edges to the
other sections, a ball of the proper shape is ob
tained. The sections are made of tough flexible
35 material preferably leather. In the drawing, a
football made in this manner is shown, and pref
erably the cover comprises four such sections.
To secure the sections together, the edges of the
cover, was that the stitching extended through
to the outer surface of the cover and hence was 15
subjected to undue wear.
In the present instance, the valve structure is
adapted to be secured to the cover at a seam
therein, and the inflation opening, indicated at
2li, thus is placed at the seam. The opening 20
is preferably closed by a dust cap or plug 2l.
To this end, the means for securing the valve
structure in place is shaped to fit over the in
turned edges H of the cover sections and occu
pies but little space within the cover. In this
present instance, said means comprises a flexible
member 22, such as rubber, having a channel
shaped portion 23 dimensioned to fit snugly on
and bridge the inturned edges Il of the cover
sections.
The channel-shaped portion 23 has
substantial length longitudinally of the seam and
is given a slightly arcuate shape to conform to
the shape of the ball. The member 22 also has
30
two relatively ilat portions 24 extending side
wardly from the channel and lying flatly against
the cover on the respective sides of the seam.
The fiat portions 2li together have a disk shape.
The preferred means for attaching the member

of the cover. By so doing, the heavy inturned
edges of the cover sections were avoided and the
valve structure was attached to the cover at a
point where the cover was relatively flat except
structure. The latter is secured to the cover by
means of the member 22 which has portions 24
lying flat against the inner face of the cover.
Between the portions 213 is the channel-shaped
portion 23 which ñts snugly over and bridges the 75

2,118,325
inturned edges ll of the sections of the cover.
Thus, the valve structure is positioned at a seam
in the cover in a manner which avoids any large
bunch of material, and access thereto is had
through the opening 20 which is at the seam.
The channel-shaped portion 23 is of substantial
` length and is arcuately shaped to conform to the
contour of the ball. The stitching holds the
member 22 firmly in place, and in the preferred
form shown in Figs. 3 and 4 doe-s not extend to
the outside of the ball where it would be sub
jected to wear.
From the foregoing, it is apparent that I have
provided in an inflatable ball a valve structure
and means for attaching it to the cover, which
is secured to the cover at a seam joining two
sections of the cover. The means for attaching
the valve structure conforms substantially to the
shape of the cover and its seam so that the bladder
is not unduly distorted by said means. This con
struction also permits the valve structure to be
placed diametrically opposite the means for clos-l
ing the bladder insertion opening in the case of
a ball such as a football, so that the ball is well
balanced. In attaching the valve structure to
the cover, the relative freedom between the lining
and the cover proper is not interfered with.
ThisA construction also permits the stitching for
attaching the valve structure to the ball to lie
wholly within the ball, thereby avoiding unneces
sary wear on this stitching.
I claim as my invention:
