I, WILLIAM LYON of 161 Pye Bank, Sheffield in the County of York Gas Engineer
do hereby declare the nature of my said invention for AN ADJUSTABLE VALVE FOR GAS
BURNERS, AND OTHER SIMILAR PURPOSES, to be as follows
:-
My invention of an adjustable valve to be applied to, or used in conjunction with
gas burners, but which may be used for other similar purposes is constructed as
follows, but there may be modifications and alterations in the details without departing
from the spirit of my invention.
I make the valve in two principal parts, a lower cup shaped part intended to be
attached to the gas fitting, having an inside and an outside screw-thread and a centre
hole or valve seat leading to the gas supply; and an upper part or lid made to fit into
the lower part by means of a screwthread, and provided with a central depending
cone or valve, which (being central) will, when the two parts are screwed together, fit
into the hole or seating in the lower part, and if scrowed down will gradually reduce
the opening and will eventually close the inlet altogether.
Through the top or sides of the upper part or lid, holes are formed to allow the gas
to escape to the burner, which is held in a cover which screws on the outside screw
before mentioned.
The coned valve may be made adjustable by providing it with a screwthread passing
through the lid or top of the upper part, and instead of scrowing the lid into the lower
part the screw-thread may be dispensed with and the parts be left plain, and simply
fit one into the other-like the slide of a Telescope.

An Adjustable Valve for Gas Burners and other similar Purposes.
I, WILLIAM LYON of 161 Pye Bank, Sheffield in the County of York Gas 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
statement:-
--
My invention of an adjustable Valve to be used in conjunction with gas burners,
(but which may be used for other similar purposes) is for the purpose of regulating
the flow of gas to the point of ignition.
And, that my invention may be clearly understood, I annex a sheet of drawings
illustrating same; the same lotters of reference indicato tho same or similar parts in
any of the figures in which they occur.
Fig. 1, is a sectional elevation of a gas burnor made according to my invention.
Fig. 2, is a sectional elevation of a modified arrangement of saine.
Fig. 3, is a sectional elevation of another modified arrangement of samo.
In carrying out my invention as shown in Fig. 1, for example, I make the valve in
two principal parts A and B ; the lower part A is to be fixed to the usual gas bracket
or other fitting by means of a screw thread round its base.
The upper part of A is screwed both internally and externally, and is also provided
with a small communicating passage C, which forms the seating for the valve pin D.
The part B is made in the shape of a lid screwed on the outside to correspond and
fit into the part A, so that it can be raised and lowered by being turned with the
fingers.
In the centre of the top plato of the lid, a cone depends in such a manner that when
the lid is screwed down the cone will enter the passage before mentioned and eventually
close it, so as to prevent the passage of gas, but when it is not closed the gas can pass
to the burner through holes in the top of the lid.
The arrangement shown in Fig. 3, is a modification of the principle before described.
The cap or lid B is not made with an outside screw, but is plain, so that it can be
pressed tightly into the part A, and the cone or valve pin D is in the form of a screw
that can be adjusted by the fingers, so as to gradually close the gas passage C.
The arrangement shown in Fig. 2, shows another modification, the part marked B
is dispensed with, the part A is chambered out and the-conical endod screw forming
the valve is screwed through a corresponding hole in the top, the escape holes being
made through the sides of the chamber.

page_text: Although the conical valve in the three drawings is shown with the point downwards,
its position may be reversed, in which case it would be fixed to the lower part A, and
a seating or passage for the gas would be made through the top of the part B.
The valve is enclosed in the cover E, which carries the actual burner F, which may
be of metal, clay, or other material.
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:-
In adjustable valve for Gas burners, and other similar purposes, (such as the supply
pipes to gas stoves) the novel arrangement of the parts A,and B, in combination with
the cone D, and the passage or seating C, substantially as herein before described, and
as illustrated in the Figures 1, 2, 3 of the drawings.
