1, HENRY Cox Junior of 15 George Street Mansion House in the City of London,
Gas Engineer, do hereby declare the nature of this invention to be as follows:-
-
This invention has for its object the proper blending of gas with common air
for the purpose of bringing about a more perfect combustion, which is at present very
imperfect, wasteful and dangerous.
1 am aware of certain air chambers used in combination with gas taps for gas
stoves generally but the nature of my invention is to more completely control the
proper blending of gas with common air, 1 carry my invention into effect by
means of a tap containing within its parts the air chamber, this tap by means of
a mechanical contrivance preferably a screw is adjustable and can be brought to
any desired nearness to the flow of the gas, this tap is fixed to the supply pipe
at any convenient situation with respect to the point of combustion and the inflow of
gas is at right angles with the supply pipe which avoids the necessity of a screw
and washer.
By the setting of the adjusting screw the proper blending of gas and common air
is effected and the plug of the gas tap is held firmly in its proper position and
more perfect combustion is thereby attained.

page_text: I, HENRY Cox Junr. of 15 George Street Mansion House in the City of London
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:-
This invention has for its object the construction and arrangement of improved
apparatus for the proper mixing or blending of gas with common air for the purpose
of bringing about a more perfect combustion, which, at present is very imperfect
and wasteful of gas, as well as dangerous.
For the purpose of more clearly describing my said apparatus, I have appended
thereto a sheet, of Drawings, shewing one form of Apparatus for carrying my
invention into operation, and in each figure the same letters of reference indicate
similar parts Fig. 1 is an elevation Fig. 2. is a sectional elevation shewing both outer
and inner cases in section Fig. 3 is a plan section through the dotted lines at L. M
on Fig. 1.
In the said apparatus I carry my invention into effect by means of an instrument
which I have termed a Tap A which has one or more holes B. of suitable size cut
on the periphery, both of outer and inner cases, and within the inner_casing is the
air chamber C. wherein the gas issuing from the orifice of the pipe H and the air
introduced through the adjustable holes B. in the casings are mixed or blended.
The inner casing revolves with the screw or plug D and thereby the air holes B are
adjustable in the manner, as is the hole in the screw or plug for the introduction of
the gas and in consequence this tap, by means of a mechanical contrivance such as a
screw D, but which I now find is better actuated by an ordinary plug is perfectly
adjustable and simultaneously controls the inlet of common air by means of the
inner casing E in the interior of the air chamber, having the holes B corresponding
to those in the outer casing, and in which casing E is attached to the adjustable screw
or plug D herein before mentioned, and revolves with the said adjustable screw or plug
by a cross bar swivel shewn clearly at E in Fig. 3 attached to the inner casing in the
interior of the air chamber.
This tap is fixed to the supply pipe at any convenient situation with respect to the
point of combustion and the inflow of gas through the pipe G is at right angles with
the supply pipe. By the setting of the adjusting screw or plug D the air is also
simultaneously admitted in proper proportions through the holes B to the air chamber
and the proper blending of gas (which is passed through the tap D. by means of the
pipe H) and common air (through the holes B) is effected and the plug or screw D
of the gas tap is held firmly in its proper position and a more perfect combustion
is thereby attained. The gas and common air after blending is carried through the
pipe K to the burner or burners.
I would remark that I do not bind myself to the exact details herein described as
many modifications may be made in the details of the Apparatus such for instance 4
using a revolving disc at the bottom of the air chamber instead of the revolving
casing E for the admission of air to that chamber.

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. The apparatus herein before described for controlling the quantities of gas and
common air in the proper ratio for mixing or blending in relative proportions for
proper combustion.
2. The combination of the adjusting screw or plug at the base of the tap A together
with the inside revolving casing E as hereinbefore described, and for the object
hereinbefore mentioned.
