Position of Punctures in the Tyres of Cycles or such like Vehicles.
I, CHARLES EDWIN CORBITT, of 57, Market Street, Chorley, in the County of
Lancaster, Ironmonger, do hereby declare the nature of this invention to be as
follows;
My invention has for its object a new or improved method of and means for
ascertaining the position of punctures in tyres of cycles or such like vehicles whereby
the position of the smallest puncture will be easily ascertained in a quick and expe-
ditious way by means of filling the tyre with water or other fluid and this I effect
in the following manner.
To an ordinary air pump either at the rear end or at any convenient position
I fit a small stop valve to this I attach a tube made of any light suitable material
to insert into the water or other fluid with which it is intended to fill the tyre, the
action of the pump of course forcing the water into the tyre.
Instead of having a stop valve made in the pump I may simply employ a separate
tube which is so made that it can be attached to the end of the pump, this tube
would have another short piece of tube attached to it at right angles for the purpose
of inserting in the water or fluid a stop valve if necessary being made at the junction
of the two tubes.
The action being, of course, when a puncture occurred to attach either of the tubes
made as before described to the ordinary air pump and inserting the one end of it
in water or other fluid and so filling the tyre with it through the ordinary Dunlop
or other valve in the tyre, any puncture however minute will be at once made
apparent by a fine jet being ejected thus obviating the necessity as is now the case
of wetting the whole of the outside of the tyre.

A New or Improved Method of and Means for Ascertaining the

in and by the following statement:-
My invention has for its object a new or improved method of and means for
ascertaining the position of punctures in tyres of cycles and other such like vehicles
whereby the smallest puncture will be easily ascertained in a quick and expeditious
manner by means of filling the tyre with water or other fluid and this-I effect
in the following manner:
To an ordinary pump either at the rear end or any convenient position I fit a
small non-return valve to this I attach a tube made of any light suitable material
to insert into the water or other fluid with which it is intended to fill the tyre
the action of the pump of course forcing the water into the tyre..
Instead of having a non-return valve made in the pump I may simply employ a
separate tube which is so made that it can be attached to the pump this tube would
have another short piece of tube attached to it at right 'angles for the purpose of
inserting it in the water or fluid, a non-return valve if necessary being made at the
junction of the two tubes in this case.
.
The action being when a puncture occurred to attach either of the tubes made as
before described to the ordinary air pump inserting the other end of it in water or
other fluid and so filling the tyre with it through the ordinary Dunlop or other
valve in the tyre any puncture however minute will be at once made apparent by
a fine jet being ejected thus obviating the necessity as is now the case of wetting
the whole of the outside of the tyre.
In order that my invention may be more clearly understood and carried into
practice I have appended hereunto a sheet of drawings upon which:-
Figure 1 is a view of an ordinary inflator or pump with my invention attached in
one way.
Figure 2 is a broken off view of a different kind of inflator or
Figures 3 and 4 are views of two modifications of my invention.
pump.
To an ordinary inflator or pump A either at the rear end as shown in Figure 1
or at any convenient position I fit a small valve and nozzle a¹ and to this I attach a
tube B made of any light suitable material.
In the example shown by Figure 1 the action would be as follows:-Immediately
a puncture is made and the rider is desirous of discovering its whereabouts the
pump A is attached to the tyre valve in the usual way the tube B is attached to
the valve and nozzle a¹, by means of the coupling a², at the rear of the pump and
this nozzle al may be covered with a cap when not in use, the one end of the tube B
is inserted in the water or other fluid with which it is intended to fill the tyre,
the ordinary action of the pump forcing a mixture of air and water into the tyre, any
puncture however small will at once be made apparent by squeezing the tyre
causing a fine jet or spray of water and air to be ejected which on its escape causes a
whistling noise to be heard; and enabling the rider to easily locate and mend the
puncture.
The tube B can be made of any suitable length to carry in' the valise or pocket
and the valve and nozzle a¹ may be made in the inflator at any position.
Figure 2 is a broken off view of an inflator which has the plunger or handle for
pumping at the rear end in this case the tube B would be attached to the nozzle
end C by taking off the ordinary tube which is used for the air, the tube B would
have, a non-return valve formed in its coupling or end a² instead of in the inflator.
In a modification of these modes I make an attachment as shown by Figure 3.
E is the tube for inserting in the water or fluid and has a non return valve formed
in the junction piece e. F is the nozzle for attaching to the pump or inflator A
and may have a non return valve formed in it, the other end H is for attachment
to the ordinary tyre valve; the action being exactly similar as for the ones before
described. Figure 4 is made exactly as described for Figure 3 but has a hollow
rubber or other ball G terminating the tube E which may be filled with water or
fluid before starting on a journey.

page_text: 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:
A new or improved method of and means for ascertaining the position of punctures
in the tyres of cycles or other such like vehicles substantially as herein described
and shewn upon the drawings.
