Improvements in Valves particularly adapted for use with Pneumatic
or Air-inflated Tyres.
I, WILLIAM HEALE, of 193 Battersea Park Road, Battersea, in the County
of Surrey, Chemist, do hereby declare the nature of this invention..to be as
follows:
My invention relates to an improved non-return valve, specially adapted for use
with pneumatic or air-inflated tyres for the inflation thereof, the object: being,. the
perfection of this type of valve for the special purpose.for which it is intended.
I construct my improved valve in the following ranner;-Itakesarshort length
of rubber tube and to adapt the one end to form a valve seat I turn the end back,
i.e., inside out, and fix it..by cementation, vulcanization, or in any other suitable
manner. By this means I am enabled to get a perfectly square end to the tube
which is not possible by.simply cutting or shaping the end. Theyflap of the valve
consists of a square piece of fat metal-preferably, gunmetal-the size of which
across is just equal to the diameter of the turned over end of the tube. This metal
flap is kept down on to the end of the rubber tube by: two strips of rubber crossing
the said metal flap at right angles to one another, the ends of the said rubber strips
being fixed to the rubber tube in any convenient manner. These rubber strips act
as springs.to.keep the metal flap down on the end of the rubber tube and confine
its position thereon.
It will be seen that with this construction of valve the air can be instantly
released from a tyre by pushing a rod, or its equivalent, up the rubber tube; and so
lifting the metal flap off the valve seat formed by the end of the,said rubber tube.

COMPLETE SPECIFICATION.
Improvements in Valves particularly adapted for use with Pneumatic
or Air-inflated Tyres.
.
I WILLIAM HEALE of 193 Battersea Park Road, Battersea, in the County of
Surrey, Chemist, .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 an improved non-return valve for pneumatic or air-
inflated tyres, and the objects of my improvements are, first, to provide for the
deflation as well as the inflation of the. tyre, second, to reduce the chance, of
accidental damage to the valve and third, to simplify the construction of valves used
for this purpose, and to increase their efficiency.
I attain these objects by the construction illustrated in the accompanying drawing,
in which;
Figure 1 isa vartioal elevation

page_text: Figure 3 a plan thereof;
Figure 4 a vertical elevation of the rubber inflation tube out of which the valve
seat is formed;
Figure 5 a vertical clevation of the inflation tube with the valve seat formed;
Figure 6 a vertical elevation of the valve complete showing the method of
attaching it to the air tube of the tyre; and
Figure 7 is a vertical section of another form my invention may assume.

out.
The seating a of the valve.is formed on the end of the inflation tube A. (which is
preferably made of rubber) by turning back the end thereof, i.e., turning it inside
This forms a perfectly true end to the tube, and enables the valve B--which
preferably takes the form of a square, or approximately square plate-to
hermetically close the end of the inflation tube A with a minimum amount of
pressure. I confine the valve B on the end of the inflation tube A by two clastic
strips C, C, formed of rubber or other suitable elastic material-passed over the
said valve at right angles to one another and then cemented or otherwise attached
to the side of the tube A, and also to one another if desired, a slight tension being
given to the said elastic strips. It will thus be apparent that these elastic strips
serve the double purpose of confining the valve on its seating and acting as springs
to keep it thereon. Instead of passing the elastic strips C, C, over the top. of the
valve B they may pass through it-suitable holes b, b, formed therein as shown
by Figure 7 of the accompanying drawing. The valve B may be made of metal,
vulcanite fibre, or any other suitable material.
The elastic strips C, C, may be attached to the turned over end of the inflation
tube A in the manner illustrated by the accompanying drawing, i.e., by cementation
and an exterior binder c, or they may be attached in any other convenient and
suitable manner, either before or at the same time as the inflation tube A is fixed
to the air tube X of the tyre.
It will be seen that although this is a non-return valve, the air tube of the tyre
can easily and readily be deflated by lifting the valve B off its seating a, by pushing
a rod or bar up the inflation tube A.
This construction of valve is exceedingly simple, not liable to get out of order,
and is inexpensive to manufacture.
I wish it to be particularly understood that I do not limit myself to the precise
details of construction herein before described and illustrated by the accompanying
drawing, but that I hold myself at liberty to make such changes and alterations as
fairly fall within the spirit and scope of my invention.
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
1st. The improved valve for pneumatic or inflated tyres, constructed, arranged,
and operating as hereinbefore set forth.
2nd. The combination in a valve for pneumatic or inflated tyres, of the rubber
inflation tube having a turned over end forming a valve seating, of the flat plate
valve, and of the elastic strips passing over the said valve and confining and
holding it down on to its seating, all substantially as set forth.
3rd. The combination in a non-return valve for pneumatic or inflated tyres, of
an inflation tube having a seating formed on its one end by turning back the said
end on itself, i.e., inside out, of a flat plate valve, and of two clastic strips passing
over the said plate valve at right angles to one another thereby confining the said
valve on its seating but allowing it movement for its action, as set forth.
4th. The combination in a valve for pneumatic or inflated tyres, of the rubber
inflation tube having a turned over end forming a seating for the valve, of the flat
plate valve adapted to rest on the said seating, and of the elastic strips passing at
right angles to one another through holes formed in the said plate valve and

purpose set forth.
