Improvements in Valves,
CLEMENT COURTNEY Engineer 25 Ashbrook Road Upper Holloway-
London N. do hereby declare the nature of this invention to be as follows:-
This my invention has reference to an improved valve more especially
applicable for use in combination with pneumatic tyres for cycles or other vehicles..
My invention has for its object the remedying of a defect in air valves, but more
particularly in my patent valve No. 5506 March 1894 which has a plug with.
washer & seating but which plug is liable to turn round when the pump is screwed
on and causes abrading & cutting of the washer. My invention has for its object
the remedying of this defect. This I do by making a portion of the plug square
which square fits into a square hole in end of body of valve and so makes it
impossible for the plug to turn thus remedying the defect mentioned.

Improvements in valves.
I CLEMENT COURTNEY, of 25 Ashbrook Road, Upper Holloway, London, N.,.
Engineer, 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 specification
:-
This invention relates to that class of valve commonly used in connection with
pneumatic tyres for cycles and the like, but which may also be used for inflating-
other articles with air gas or fluid.
Valves such as that referred to have heretofore been constructed with a screw-.
threaded nipple to which the nozzle of the inflator is attached. Now it has been.
found that the nipple is apt to turn in that portion of the remaining part of the
valve made for its reception, and that by so doing the leather or other washer
wears and allows air, gas, or fluid to escape.
The object of this invention is to obviate the disadvantage above set forth, in a
simple and efficacious manner, hereinafter described and illustrated in the drawings.
hereunto annexed, in which ;—
Fig. 1 is an elevation shewing a valve embracing my invention.
Fig. 2 is a section of the valve shewing my improvement.
The valve comprises the two parts A and B united by the cap nut C. The
part B is screw-threaded as shewn to enable the nozzle of the inflator to be
attached thereto and to receive the dust cap E.
It will be observed that the part B enters the part A at F which by my present
improvement is square, or may have one or more flat surfaces, engaging corre
sponding flat surfaces in the part A, thus preventing the part B from turning.

page_text: 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.) In a valve such as that herein before described the nipple or part B formed
with a squared or flattened portion engaging a corresponding seat made for its
reception in the part A substantially as and for the purposes hereinbefore set
forth and illustrated in the drawings hereunto annexed.
(2.) In a valve such as that herein before described the parts A and B connected
in such manner that the part B cannot turn on or in the part A, for the purpose
hereinbefore set forth.
