Improvements in
in or relating to Valves for Pneumatic Tyres
Employed in connection with Wheels of Bloycles, Tricycles,
and other Road Vehicles.
I, JOHN SHIPWAY of 29 Brierley Street, Rose Hill, Bolton in the County of
Lancaster, Hair Dresser, do hereby declare the nature of my said invention to be
as follows:-
This invention consists of improvements in or relating to valves for pneumatic
tyres employed in connection with wheels of bicycles, tricycles, carriages and other
road vehicles and consists in an unique arrangement and disposition of parts
whereby the same may be readily attached and detached when requisite for
repairs and other purposes. This I accomplish by securing to the rim of the
wheel-in any convenient manner a stern with an internal valve seat into which
is screwed a stem, the upper end of the latter being provided with a valve face
to operate against the aforesaid valve seat. In the casing surrounding the valve
is placed a spring or its equivalent according to the kind of valve employed. The
various parts of the valve casing are constructed with double joints or faces both
internally and externally. The valve may be made of metal or any other suitable
material, aud provided with a face of india-rubber, gutta-percha, or other equivalents.
The outer end of the screwed stem containing the valve seat is provided with a
screwed end to allow of a pump being attached when the air tube requires to be
inflated. In another modification I provide a pin or spindle with a valve so as to
form two shoulders or faces opposite each other. The valve spindle or pin between
the said shoulders or faces is conical in form inclining downwards from the centre
in which centre lies the end of an air passage through the valve. The space
between the shoulders or faces is provided with an elastic or india-rubber tube or
its equivalent in such a manner that the air when inflation is being performed in
the pneumatic tube the air escapes from both sides of the said india-rubber tube or
its equivalent. To ensure of simple and perfect joints I provide washers of leather
or other suitable substance provided internally with threads for the purpose of
screwing them on to the internally or externally screwed joints, which also prevents
the said washers being lost when removing the valva. The valve shaft or pin is
provided with a sunk surface so as to leave two shoulders or faces opposite to each
other below the threads of internal screw joint and above the sunken part of pin
or spindle covered with india-rubber or its equivalent for the purpose of inserting
packing to ensure of making the valve air-tight.

I, JOHN SHIPWAY of 29 Brierley Street, Rose Hill, Bolton in the County of

in what manner the same is to be performed, to be particularly described and
ascertained in aud by the following statement :-

page_text: upper end of the screwed stem A containing the valve seat B is provided with the
screwed end I to allow of a pump being attached when the air or pneumatic tube
requires to be inflated. The lower end of the spindle C is provided with the
shoulders or faces M and O opposite each other. The spindle C between the said
shoulders or faces M and O is conical in form incliuing downwards from the centre
in which is situated the outlet P at the end-or nearly so-of the air passage R
in the stem C. The space between the shoulders or faces M and O is provided
with the elastic or india-rubber tube S or its equivalent in such a manner that the
air when inflation is being performed in the pneumatic tube or tyre the air escapes
from both ends of the india-rubber tube S. To ensure of simple and perfect
joints being made the washers T are employed composed of leather or other
suitable substance provided internally with threads for the purpose of screwing
them on the internally and externally screwed joints, which screwing prevents the
washers T being lost when removing the stem C. The valve spindle or stem C is
provided with a sunken surface so as to leave the shoulders or faces M and O
opposite to each other below the threads V of the internally screwed joint and
above the sunken part of the piu or spindle C, covered with the india-rubber
tube S or its equivalent for the purpose of inserting the packing H to ensure of
making the valve or stem C air-tight. The nuts X and the clip Y are provided
for securing the same to the rim of the wheel. The outer end of the stem C is
provided with the screwed part I to receivo the cap or cover W, the latter being
secured to one of the spokes of the wheel by a chain or its equivalent.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The general arrangement, construction, and combination of parts composing
the improvements in or relating to valves for pneumatic tyres employed in connec-
tion with wheels for bicycles, tricycles, and other road vehicles, substantially as
herein before described and as illustrated in the annexed drawing.
2. In valves for pneumatic tyres the combination of the screwed stem A, clip Y,
nuts ✗, spindle C with the passage R, and recessed end containing the elastic or
india-rubber tube S, outlet P, caps W and Z, and the joint rings H and T, the
whole being constructed as described and as illustrated in the annexed drawing.
