Improvements in Valves for Pneumatic Tyres and other purposes.
We, RICHARD MORGAN, of 33, Hingeston Street, Brookfields, Optician, anl
JOHN HUNT, of The Royal Mint Inn, 200, Icknield Street, Inn Keeper, and both
of Birmingham, in the County of Warwick, do hereby declare the nature of our
said invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
Our invention has for its object improvements in valves for pneumatic tyres and
other purposes which are exceedingly simple in their construction and number of
parts and not at all likely to become inoperative in their action.
In order that our invention may be clearly understood and more easily carried
into practical effect we have appended hereunto a double-sized sheet of drawings
upon which we have illustrated an example of the same.
Figure 1 is a side elevation of the air valve and junction sleeve for connection to
the tyre T all complete, and we have shown in this figure a supposed section of
wheel rim R with the tightening nut N all in approximately the position they
would occupy in practice, only that it must be understood that our invention only
applies to the lower portion or valve V and its seating W, the remaining portions
before mentioned being common to most valves.
Figure 2 is a broken off sectional elevation of a portion of the sleeve and the
valve seat W and valve V in their working positions.
Figure 3 is a part elevation and part section of the sleeve S.
Figure 4 is a sectional elevation of the valve seat W with the valve V removed
and separated from the sleeve S.
Figure 5 is an elevation of the valve seat W.
Figure 6 is an elevation of the valve V removed and separated from the valve
seat W.
Figure 7 is an elevation and plan of the plug X.
Figure 8 is a plan of the sleeve S Figure 3.
We have before said that the upper portion or sleeve S forms no part of our
present invention, but is simply shown as an example to illustrate the connection
with our new valve V and seating W. Our new valve and seating is manufactured
out of one piece of metal with a milled collar or hexagon nut formed in the centre
of the valve V for tightening or undoing the valve out of the sleeve S. The valve
seating W is screw threaded at w¹ and w² the one end w² to enter the sleeve S and
the other end w¹ for the cap C to keep the dust from getting inside the valve
seating W. We then drill the hole w down the centre and form a conical seat w
for the reception of the valve V, and then screw thread the inside top portion w
of the seating W for the plug X which has two grooves x¹ and 2 cut in, so as to
allow the air to pass through into the tube when being inflated. It also prevents
the valve V from dropping out of the seating W when being inflated. The
sleeve S is screw threaded at s¹ to receive the valve seat W. The action is as
follows: The nozzle of the inflater is screwed on to the valve seat at w', and the
moment air is pumped into the valve seat the valve V is forced inwards against
the plug X, which allows the air to pass through the two holes x and x into the
tube T. When the inflater is taken off the valve seat the air forces the valve V
into its seat w' which closes the valve.
