PROVISIONAL SPECIFICATION.
Improvements in or relating to Pump Connections for Pneumatic
Tyres.
We, JAMES JELLEY and HENRY JELLEY, of Parkside, Coventry, in the County
of Warwick, Managers, do hereby declare the nature of this invention to be as
follows:-
This invention relates to pump connections for pneumatic tyres, the object
being to prevent the leakage between the pump nozzle and the valve during
inflation, which at present is a frequent source of annoyance.
In carrying out the invention we provide a socket which contains a rubber or
equivalent pad or washer, the socket being arranged to screw upon the valve
nipple of an ordinary pneumatic tyre valve. By the use of this fitting the
washer at present frequently employed inside the connection at the end of the
flexible tube of the pump can be dispensed with, a point of some importance as
that washer frequently when the pump is screwed down, closes up and prevents
the passage of air; this difficulty is absent with our fitting.
The fitting above described is suitable for use in existing valves; where it
is applied to new valves we may form the socket upon the present valve cap,
but otherwise the construction and operation are the same.
In a modified arrangement we form the socket upon the connection or nozzle
of the pump flexible tube, so that the pad lies at the open end and makes a

case the pump socket or nozzle may be made complete with this fitting forming
part of it, but if preferred the fitting may be adapted to screw on to or into the
pump nozzle, just as the one previously described is adapted to be screwed on
to the valve nozzle.
This fitting can be used with valves of various construction, so that we do
not bind ourselves to use it only with the wellknown Woods or Lucas valves,
such as we have previously been referring to.

COMPLETE SPECIFICATION.
Improvements in or relating to Pump Connections for Pneumatic
Tyres.
We, JAMES JELLEY and HENRY JELLEY, of Parkside, Coventry, in the County
of Warwick, Managers, do hereby declare the nature of this invention and in

page_text: what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to pump connections for pneumatic tyres, the object
being to prevent the leakage between the pump nozzle and the valve during
inflation, which at present is a frequent source of annoyance.
In carrying out the invention we provide a socket which contains a rubber or
equivalent pad or washer, the socket being arranged to screw upon the valve
nipple of an ordinary pneumatic tyre valve. By the use of this fitting the
washer at present frequently employed inside the connection at the end of the
flexible tube of the pump can be dispensed with, a point of some importance as
that washer frequently when the pump is screwed down, closes up and prevents
the passage of air; this difficulty is absent with our fitting.
The fitting above described is suitable for use in existing valves; where it
is applied to new valves we may form the socket upon the present valve cap,
but otherwise the construction and operation are the same.
In a modified arrangement we form the socket upon the connection or nozzle
of the pump flexible tube, so that the pad lies at the open end and makes a
tight joint against the cap of the valve when the pump is screwed on. In this
case the pump socket or nozzle may be made complete with this fitting forming
part of it, but if preferred the fitting may be adapted to screw on to or into the
pump nozzle, just as the one previously described adapted to be screwed on
to the valve nozzle.
This fitting can be used with valves of various construction, so that we do
not bind ourselves to use it only with the wellknown Woods or Lucas valves,
such as we have previously been referring to.
In the accompanying drawings which illustrate several forms of fittings all
according to this invention,
Figure 1 is a perspective view showing a pump connector according to this
invention, a portion being broken away for the sake of clearness;
Figure 2 is a vertical section through the centre of Figure 1;
Figure 3 shows in perspective a pump nozzle, and
Figure 4 is a similar view showing a portion of a valve.
Like letters indicate like parts throughout the drawings.
The connector shown in Figures 1 and 2 is for use with existing valves for
pump nozzles; it comprises a metal portion A, screwed at A¹ to enter the pump
nozzle, and at A2 to receive the valve nipple. The upper and lower faces are
recessed as at A³ and A+, respectively, and rubber washers B B are inserted in
the recesses.
Figure 3 shows a pump nozzle C, the top face of which is recessed similarly
to that of the connector A (Figure 1) to receive a rubber washer B. The nozzle C4
is provided with the usual stem CI over which the rubber tube of the pump fits,
and its upper part is internally threaded to screw on to the valve nipple in the
usual way.
Figure 4 illustrates a portion of a valve D having a rubber washer B inserted
in its top face in a similar way to that described with reference to the fittings 4
illustrated in Figures 1, 2 and 3.
When a fitting having a plain face is screwed upon another fitting provided
with a pad or washer in the manner herein described, the washer is compressed
and an air-tight connection results, the recess serving to prevent the washer from
being squeezed out from between the contiguous faces of the fittings.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed we declare that what
we claim is:
5
1. The combination with a valve or pump nozzle for a pneumatic tyre of a
rubber or equivalent pad or washer contained in a recess formed to receive it 5

page_text: in the face of the said valve or nozzle, substantially as and for the purpose
described.
2. A connector for use between the pump nozzle and valve of a pneumatic
tyre having rubber or equivalent pads or washers contained in recesses in its
faces, substantially as and for the purpose described.
3. The complete pump nozzle substantially as described and illustrated in
Figure 3 of the accompanying drawings.
4. The complete valve fitting or pump fitting substantially as described and
illustrated in Figures 1 and 2 or Figure 4 of the accompanying drawings.
Dated this 3rd day of March 1899.
