with the outer cover of the playing ball.

‘Another object of my invention is to provide

therefor which may be assembled either with the

stitch line between panels ‘or which is provided
with an in?ating opening.
A further object is the provision of a playing
ball construction which may also be used in combination with a cover formed by stitched segments of fabric on the outer surface of which
panels of leather or the like may be secured by
cementing.

The nipple
thus serves for properly locating the bladder, and
guiding the valve stem, and the ?ange on the
valve cements the bladder and ball cover together. 55

The cementing of the valve ?ange to the cover
and the cementing of the valve ?ange to the
bladder makes a substantially leak-proof joint.
In Fig. 3, the cover panels may be cemented in
5 position on an inner fabric ball 1). The lining
may be of fabric panels permanently and uni
formly stitched throughout with the outer cover
panels cemented in position without stitching.
The lining is, like the leather cover, susceptible
10 to adhesive. In this type of playing ball I may
provide an additional reenforcement which con
sists in the ?exible disc a which is of greater ex
tent than the‘?ange b; Preferably made of rough
surfaced leather, adhesive as indicated at r is
15 provided on the upper surface of the ?ange q, and
adhesive as indicated at s is provided on the under
5‘ surface, so that whereas ‘the attachment of the
/ valve ?ange to the cover, where the ball is un
lined is adequate where the diameter of the disc
20 is, for example, one and one-half inches, when a
fabric inner ball is used covered with leather
panels, the attachment is provided by a disc, for
example, three inches in diameter. It will be ob
served that in the construction shown in both
25 Figs. 2 and 3, the contour of the panel of the
cover is in no way disturbed by the attachment
of the valve ?ange thereto. This promotes accu
rate bouncing of the playing ball and avoids the
formation of a non-resilient dead spot where the
80 attachment of the valve, bladder and cover oc
a so-called stitchless ball in which they outer
cover is formed of segments of leather cemented
in position.
Having thus described my invention, what I
claim as new and desire to secure by Letters Pat
ent is:
1. A valve for an in?atable article having a :
wall with an opening through which a stem of
said valve extends said stem having a ?ange se
cured to said wall, said stem having a slit ex
tending lengthwise therethrough for in?ating said
article, a resilient band surrounding said stem
for sealing said slit and means covering said re
silient band and additionally constricting said
band for preventing deterioration of the resiliency
of said band.
2. A valve for an in?atable article having a
wall with an opening through which a stem of
said valve extends saidstem having a ?ange se
cured to said wall, said stem having a slit extend 20
ing lengthwise therethrough for in?ating said ar
ticle, a resilient band surrounding said stem for
sealing said slit and means covering said resilient
band for preventing deterioration of the resiliency
of said band, said means comprising a relatively 25
wider resilient band covering both ends of said
?rst noted band.

3. A valve for an in?atable ball comprising a
stem having a slit extending through said stem
and a resilient band surrounding said stem with 30
resilient means surrounding and enclosing said
band for the purposes described.
4. A valve for an in?atable ball comprising a
slitted stem with a tensioned band compressing
said stem to prevent leakage through said slit, and 35
means enclosing said band and constricting it for

of balls constitutes the entire ball, the cover be

I have shown my invention in combination with
a playing ball of the laceless type, but it will be
understood that the same construction may be
used in combination with a laced ball, with a ball
