I GEORGE ERNEST WRIGHT of the firm of John Wright & Co. of Essex Works,
Thimble Mill Lane, Aston in the County of Warwick Gas Engineer do hereby declare
the nature of my said invention to be as follows:-
This invention has for its object a combination valve which is specially suitable to
the purposes of minutely regulating the passage of gas. There is great waste in
cooking and heating apparatus of various descriptions because of the difficulty
experienced in properly regulating the amount of gas required for the varying necessities
of such apparatus which this invention is intended to meet.
This combination valve consists of a casing or valve box having a plunger or stalk
of a peculiar kind indeed so made as to constitute some of the qualities of the valve
and some of the qualities of the cock being as it is a combination of both valve and
cock indeed the word valve-cock accurately describes in a general respect the essence
of the invention. The body of the plunger is turned to fit the bored valve box and
either turns like a cock or lifts like a valve.
The inlet passage may be at the bottom of the valve box or at angles so long as a
seating is arranged over it by preference a taper or conical seating upon which the
valve rests when the gas is completely cut off from the burner. The plunger has a
recess or groove cut in the body of the valve which is not sufficiently long to reach
the outlet passage to the burner when it rests upon the seating but immediately it is
lifted the groove is brought opposite the outlet and the gas supply is thus brought on
but this would be a full supply. Now as the plunger is capable of being also turned
the passage may be contracted and the supply regulated without limiting the ful
rising action of the valve. This is important when applied to such purposes as tha

article upon a range stove or in an oven or other position lifts the valve up by its
weight and through the action of a suitable lever or levers.
The valve case has thus the inlet under the valve and the outlet at the side but
issuing in any direction and a suitable stuffing or other box to secure the valve in
position. An enlargement or disc is convenient upon the top of the valve under which
a lever may work to lift it and a suitable finger and index may be attached to indicate
the position of the valve to the passage.

I GEORGE ERNEST WRIGHT of the firm of John Wright & Co. Essex Works
Thimble Mill Lane Aston in the County of Warwick Gas Engineers, do hereby declare
the nature of my said invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-

This combination valve consists of a casing or valve box having a plunger or stalk
of a peculiar kind indeed so made as to constitute some of the qualities of the valve
and some of the qualities of the cock being as it is a combination of both valve and
cock indeed the word "valve-cock" accurately describes in a general respect the
essence of the invention. The body of the plunger is turned to fit the bored valve
box and either turns like a cock or lifts like a valve. The inlet passage may be at the
bottom of the valve box or at angles so long as a seating is arranged over it by
preference a taper or conical seating upon which the valve rests when the gas
pletely cut off from the burner. The plunger has a recess or groove cut in the body
of the valve which is not sufficiently long to reach the outlet passage to the burner
when it rests upon the seating but immediately it is lifted the groove is brought
opposite the outlet and the gas supply is thus brought on but this would be a full
supply. Now as the plunger is capable of being also turned the passage may be con-
tracted and the supply regulated without limiting the full rising action of the valve.
This is important when applied to such purposes as that explained in my previous
Application No. 13973 A.D. 1886 when the placing of any article upon a range stove
or in an oven or other position lifts the valve up by its weight and through the action
of a suitable lever or levers. The valve case has thus the inlet under the valve and
the outlet at the side but issuing in any direction and a suitable stuffing or other box
to secure the valve in position. An enlargement or disc is convenient upon the top of
the valve under which a lever may work to lift it and a suitable finger and index may
be attached to indicate the position of the valve to the passage.
In order that my invention may be thoroughly understood and carried into practice
without difficulty I have appended hereunto a sheet of drawings upon which I have
illustrated seven views of one of my valve-cocks.
Figure 1 is a side elevation of the valve-cock made according to my invention.
Figure 2 is a front elevation of the valve-cock shown by Figure 1.
Figure 3 is a similar view to Figure 1 but in part section on line H. K.
Figure 4. is a sectional elevation one line E. F.
Figure 5 is a cross section on line L M with the plug C so turned that the
full on
gas

page_text: Figure 6 is a cross section on line L M with the plug C so turned that the gas is
only very slightly on.
Figure 7 is a plan of the valve-cock.
It will be noticed that the plug C and handle c¹ are so made as to be practically one
piece in fact they may be cast in one so that when the handle c¹ is turned by a cook or
other person the plug passage c² Figure 6 is carried partly away from the burner
passage and this action is accomplished by hand and is quite independent of the
automatic action of the lever D upon the plug C in lifting it off its seat a². The lever D
is hung in connection with the top of any stove or the bottom of the oven or other
part so that immediately any weight comes upon the other end of the said lever D it
automatically lifts the plug C off its seat a¹ and admits a full supply of gas through
the passage a² from the gas supply pipe R and if it were not for the secondary or
turning action of the plug, the gas would always be full on which is very wasteful.
The two stops a³ and a limit the range of the handle c¹ so that when the handle c¹ is
against one shoulder the gas is full on and the automatic or lifting action of the
lever D goes on under that condition of a full supply and when the handle c¹ is against
the other shoulder there is simply the smallest possible amount of gas admitted so that
between these two any desired amount may be used.
It is evident that a pointer and scale may be used as an index if desired for the
inlet.
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 :-
-
The improved valve cock for regulating the passage of gas in cooking apparatus so
that the valve may work automatically with a small or large supply substantially as
and for the purpose herein set forth.
