JAMES WALTER COLEBROOK 66 Corporation Road Great Grimsby Lincolnshire
Ironmonger &c. do hereby declare the nature of this, invention to be as
follows:-
Ametal tube threaded inside with flange at right angles the flange being recessed
to receive a metal plug threaded outside to scrow into tube with flange at right
angles as a means of securing valve to container without projecting.
"An air passage being formed through centre of plug and threaded for inflator to
screw thereto. A valve seat is formed on end of plug and a spindle with head to forin
valve face with a washer of rubber or other suitable inaterial is passed through valve
and a spiral spring placed on spindle a head is then screwed on to spindle compressing
the spiral spring which draws the spindle forwards and closes the valve. When inflator
is screwed into air passage the connecting end bears upon the end of spindle
compressing the spring and carries the spindle forward opening valve. When the
container has been filled the inflator is unscrewed then the spring forces back the
spindle and closes the valve.

A Pneumatic Valve for Footballs, Air Beds, Air Cushions, and
the like.
I, JAMES WALTER COLEBROOK of 66, Corporation Road, Grimsby, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to a pneumatic valve for footballs, air-beds, air-cushions, and
the like, the object being to provide a valve of simple construction with which any
ordinary pump such as used for inflating pneumatic tyres, may be employed while
the said valve is arranged. in such a manner as to have no external projecting
parts.
In order that my invention may be fully understood, I will describe same with
reference to the accompanying drawings in which Fig. 1 is an elevation of the
complete valve drawn to an enlarged scale, and shown as applied to an air-bed, air
cushion, or the like.

page_text: Figs. 2, 3 and 4 are side elevations of the nipple, the inner body, and the outer
body respectively, all of which go to form the complete valve.
Fig. 5 is a vertical section through the valve shown in position but without the
inflating nozzle.
Fig. 6 is an underside view of the inflating nozzle shown at Fig. 2, and Fig. 7
is a plan of the inner body shown at Fig. 3.
My improved valve consists of an outer part (Fig. 4) comprising the stem or
shank surmounted by a hollow or recessed out head or cap a, the inner periphery
of said shank b being screwed threaded to receive the shank 6 of the inner part
(Fig. 3) which is furnished with a hollow head or cap al and it is between the inner
surface of the cap a and the outer surface of the cap a' that the bladder of a foot-
ball or the substance of an air-bed, air-cushion or the like m is gripped as shown
(Figs. 1 and 5).
The shank or stem is bored out and screw threaded to receive the inflating
nozzle (Fig. 2), a valve seat being formed at the end of the, said stem b¹ through
which passes the rod furnished with a head d' fitted with a washer of rubber or
other suitable material w which forms the valve face, while the other end of said rod r
carries a head or disc d between which and a shoulder formed near the end of said '
stem or shank is arranged the spiral spring g which forces the rod r.in an upward
direction and tends to keep the valve face d' closely against the end of stein or shank b¹,
thus closing the valve.
In order to secure my improved valve in position the outer body (Fig. 4) is first
passed through a suitable opening into the air-bed, cushion or the like, the head or
cap a being then brought up under the opening and the shank 6 of the inner.
part (Fig. 3) screwel into the shank or stem & thus gripping the substance m.of the
air-bed, cushion or the like, between the two surfaces as shown at Fig. 5, the hollow
or recessed head a' of the inner part boing fitted with a suitable, plug. p of india-
rubber or other suitable material, which is pressed into same so as to afford a flush
and even outer surface, and in the case of a football prevents the .players from being
hurt in the event of their being struck by this portion of the ball.
In order to employ my improved valve for the purposes of inflation, the plug p is
first removed and the screw threaded stem n² screwed into the top end of the shank
or stem until the end rests or 'bears against the disc or head.d of the rod r, thereby
depressing the said rod and valve seat d', and opening the valve, when the air-bed,
cushion or the like can be readily inflated by applying an ordinary cycle tyre pump
or inflator to the nozzle n. A fly-nut is provided for the purpose of enabling the
inflating nozzle to be readily screwed into position; while the face or surface of the
stem is furnished with oross cuts or channels (Figs. 2 and 6) to allow of the air
readily escaping and passing through the valve.
The hollow or recessed head a' may be furnished with two indenta or recesses e, e,
designed to engage with a suitable forked key for facilitating the screwing of
same into position.
When the football, air-bed, air-cushion, or the like has been inflated, the inflating
nozzle (Fig. 2) is removed and the plug proplaced as shown at Fig. 5, the valve being
automatically closed by the action of the coiled spring g which forces the valve face d'
closely up against the end of the stem or shank b¹.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed; I declare that what I
claim is :-
1. The new or improved valve for inflating footballs, air-beds, air-cushions and the
like, comprising a hollow shank or stem 6 having a recessed head or cap a and an inner
part comprising the screw threaded shank or stem 6 and recessed cap or head a', in
combination with valve spindle r, having disc or head d, valve seat d, and an
operating spring such as g, the whole arranged in such a manner that there are
no external projecting parts, substantially as herein described and shown,.and for the
purposes specified.
