COMPLETE SPECIFICATION,
Improvements in Valves for Inflating and Deflating Football Bladders,
Cycle and Carriage Pneumatic Tyre Tubes, and the like.
I, JASPER HARRISON, of 2, Meal Market, Hexham, County of Northumberland,
Cycle Agent, 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 is for improvements in valves for inflating and deflating football
bladders, cycle and carriage tubes and the like and is as follows:-
In the drawing Figs. 1 and 2 are sectioned to a greatly enlarged scale of the
valve, Fig. 1 being a section shewing the special inflater adapter attached, the
valve open and free to admit the air or release it. Fig. 2 is a section, shewing
the valve closed with the protecting cap screwed on.
In Fig. 1 and 2, a represents the bladder or tube which is firmly gripped on the
stalk by being nipped between the head c of the stalk b, and the washer d by
means of a nut e screwed onto the outside of the stalk b. is the valve face on the
stalk b, is the recess in the stalk and y the shoulder against which the bottom
of the spring n acts. 7 is the valve spindle with its valve i which is held in place
by a head and if necessary or preferred a nut km is a collar on the spindle /
against which the top of the spiral spring acts and o is the prolongued portion of
the valve spindle 7 screwed to receive the protecting cap with its washer u (Fig. 2).
is the nut of the inflater adapter, q is the stalk of the same, having a cone q
or projecting part to bear on the top of the prolongued part o of the spindle /, and
the washer r, and ss are the apertures for the passage of the air shewn in Fig. 1.
The description of the drawing will thus make clear the mode of action which
is as follows:
There is a stalk screwed on the outside having a head at its end within the
apparatus or object to be inflated or deflated, on the lower side of this head there
is a valve face. The stalk is suitably recessed having a shoulder towards its lower
end and the aperture or opening is continued into the bladder or tube to be
inflated or deflated.
Above the head of the stalk there is a washer of suitable shape and above the
washer there is a nut screwed on the outside of the stalk. In this way the bladder
or tube is nipped between the head of the stalk and the washer by the screwed
uut. The bladder or tube being suitably protected or strengthened so as to render
it permanently air-tight and free from rupture.
Within the aperture or recess of the stalk there is a valve spindle continued
through the stalk into the bladder or tube, and on the lower part of the spindle
there is screwed or otherwise fixed a valve head, or held in its place by a screwed
nut which may be soldered or brased on to the valve spindle so as to make it air
tight and permanently fixed on the valve spindle.
Recessed or otherwise into this valve head there is a suitable valve or washer to

page_text: act as a valve of vulcanite or leather or other suitable material, or the valve head
itself may form the valve and may be in preference a plain face or it may be a
mitre or other form of valve.
Towards the upper portion of the valve spindle within the stalk there is a collar
but sufficiently smaller than the recess in the stalk to allow the air to pass, or
there may he holes or notches to accomplish the same purpose and in the recess of
the stalk outside of the valve spindle and between the shoulder on the lower
portion of the stalk and the collar on the valve spindle there is a coiled or spiral
or other form of spring which acts or presses between the shoulder on the lower
part of the stalk and the collar on the valve spindle thus keeping the valve on
the valve spindle up to the valve face on the stalk and so preventing the egress
of air through the valve.
The valve spindle is prolongued above the collar and is there screwed and after
the bladder or tube or other object to be inflated is charged the inflater adapter
is removed and a protecting cap is inserted into the top of the stalk recess and
having a screwed hole or recess which is screwed onto the prolongued portion of
the valve spindle thus definitely drawing the valve on the valve spindle up to the
face on the stalk and holding the valve permanently tight in addition to the
pressure induced on the valve by the spiral or coiled spring. At the same time
the cap being furnished with a collar of leather or other material presses on the
top of the valve stalk and affords an additional precaution and means of preventing
any escape of air. The inflater adapter may be of the ordinary type screwed on
to the top of the inflater adapter shewn on the drawing and as herein before
described. The inflation being effected when the cap is removed by forcing the
air through the valve which is held up to its face by the spiral spring. Or it may
be deflated when the cap is removed by simply pressing on the prolongued portion
of the valve spindle and thus opening the valve. Or the inflater may be of a
special construction or contrivance. In this way.-There may be a prolongued
portion of the stalk of the inflater adapter within or inside of the nut, or screwed
portion of it having a suitable point or projection with any suitable apertures for
the air passage so that when the inflater adapter is screwed on to the upper portion
of the valve stalk already described the projecting point presses on the top of
the valve spindle thus opening the valve and allowing free ingress or egress to
or from the bladder tube, or other object to be inflated or deflated.
To render this in itself airtight, there may be a collar or washer of leather or
other material on which the inflater adapter is screwed against the upper face of
the valve stalk. When the inflater adapter is unscrewed the pressure of the air
within the bladder or tube aided by the spiral spring, at once closes the valve
and when the protecting cap is screwed on to the top of the valve spindle, the
valve head is firmly fixed against the valve face and so rendered permanently
air tight.
The valve stalk may be arranged so as to fit within an india rubber tube or
mouth piece on the object to be inflated or deflated and the inflater adapter may
be of the ordinary type or otherwise and of one or more parts as may be desired.
The various parts may be of any suitable material-thus the stalk, spindle, bead,
nut and washer may be gun-metal. The inflater adapter of a similar metal, the
spiral spring of steel the valve or other airtight washers of leather, or any other
suitable material may be used, and the shape and design may be modified to suit
the requirements of each case.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare what
I claim is:
1st. The method or means of forcing in air freely without the valve having to
lift at each stroke of the inflator together with the self acting closing spring when
the inflater is removed, where an ordinary inflater adapter is used.
2nd. The method or means of forcing in air freely without the valve having to

page_text: lift at each stroke of the inflater together with the self acting closing spring when
the inflater is removed, where a special inflater adapter only is used.
3rd. The method or means of a permanent air tight valve by the self acting
spring combined with the additional safety of the tightening by the protecting cap.
4th. The general arrangement of valve substantially as described in the speci
fication and drawing.
