Improvements in and relating to Gas-burners.
I, WILLIAM GORDON POTTER, of 99, Warwick Street, Greenheys, Manchester,
in the County of Lancaster, Consulting Engineer, do hereby declare the nature of
this invention to be as follows :—
My invention relates to gas-burners, and comprises various features of improve-
ment hereinafter described.
One.object of my said invention is to produce an improved self-regulating gas-
burner. For this purpose I employ a piston valve working in a cylinder, the
lower end of the said cylinder being connected and communicating with the hollow
stem of the burner, the said stem itself being connected to the supply pipe by a
taper screw thread in the usual manner.. Any variations of the gas pressure will
cause the piston valve to rise or fall and thus to open or close the valve. A small
passage is provided to supply the burner, with gas when the valve is closed. An
adjusting screw in the stem of the burner extending to the interior of the said stem
serves to regulate the pressure of gas acting on the piston valve.
Another object of my said invention is to provide an improved attachment for
gas-burners, designed to spread the flame therefrom, so as to increase the size of
the flame, and the intensity of light obtained from it.
This attachment consists of a flat plate or spreader, made of metal or other
Buitable material fixed vertically in a slot in a metal dome or deflecting cone which
forms the top of the burner, in such a manner that the gas shall pass on either side
of the said plate or spreader.
A further object of my said invention is to provide in a simple and economical
manner for the supply of heated air to the flame.
To attain this object, the under part of the chamber partly formed by the said
dome or deflecting cone on the top of the burner, is perforated, so that air is drawn
through the perforations and is deflected on to the flame by the said cone.
As this
Baid chamber becomes heated by the flame of the burner, the air drawn into it
absorbs heat, and this arrangement forms a regenerative burner.
By the above described arrangement of the heating chamber, the deflecting cone
or dome, and the spreader, I provide for greatly increasing the illuminating power
of the burner, and the steadiness of the flame.
These devices or attachments may be used with any suitable form of burner,
either with or without a regulator.
I provide an ordinary cock or tap for turning on or off the supply of gas to my
improved burner and a nipple of any desired construction can be used. The cook
or tap employed may have a small channel or bye-pass cut on the side of the plug,
or I arrange in some other manner to allow a small quantity of gas to pass after the
cock or tap has been closed.
My improved burner can be adapted for producing either a bats-wing or a fish-
tail flame as may be desired.

Improvements in and relating to Gas-burners.
I, WILLIAM GORDON POTTER, of 99, Warwick Street, Greenheys, Manchester,
in the County of Lancaster, Consulting 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 relates to gas-burners, and comprises various features of improve-
ment hereinaftor described.
One.object of my said invention is to produce an improved self-regulating gas-
burner.
Another object of my said invention is to provide an improved attachment for
gas-burners, designed to spread the flame therefrom, so as to increase the size of the
flame and the intensity of the light obtained.
A further object of my said invention is to provide in a simple and economical
manner, for the supply of heated air to the flame.
also provide for the adjustment of the burner by hand to adapt it for use with
higher or lower pressures as hereinafter specified.
In the accompanying drawing, I have shown how my said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a vertical central section of one form of burner constructed in
accordance with my said invention, and
Figure 2.is a plan or top view of the said burner.
a is a small cylinder or casing, which is provided or connected with a hollow
..stem b. having at its lower end a taper screw-thread for connecting the burner
to the supply-pipe in the usual manner. An adjusting-screw c is passed through
n tapped hole in the hollow stem band extends into the interior of the said stem,
for the purpose of regulating by hand the area of the passage for the flow of
gas to the cylinder or casing a. In the said cylinder or casing a is arranged
an automatic regulator comprising an annular piston or valve d, which works up
and down in the said cylinder, and a perforated inverted hollow cone e forming a
seating for the said valve d. The weight of the piston or valve d is such that
the gas entering the cylinder a. will raise the said valve more or less according
to the difference of pressure above and below the said valve, and thus regulate
the flow of the gas through the burner. Should a rush of gas into the
cylinder a take place, the valve df will be forced against the conical seating e
and the gas will then flow only through the small perforation in the apex of
the cone, until the pressure above the said cone e increases sufficiently to permit
the descent of the valve d' under the action of gravity.
The upper end of the cylinder a is perforated to permit the flow of the gas
therefrom, a perforated disc of suitable refractory material being, by preference,
fixed in the upper end of the said cylinder for this purpose. Suitable perforated
discs are, moreover, arranged in the said cylinder to serve as strainers or filters
for the gas.
On the upper part of the cylindor a is fitted a perforated metal cup to
which is secured, by a screw-thread as shown, or in any other convenient
manner, a motal dome or deflecting-cone y formed with an elongated aperture
or slit g in the top thereof. At each end of this aperture g¹ is formed a narrow
slit, and in these slits g' is fixed a flat plate or spreader h made of metal or
other suitable material, for the purpose of splitting or dividing and spreading
the flame.
The gas from the cylinder a flows upward on both sides of the spreader /

page_text: and through the aperture g¹. Air for supporting combustion enters, through the
perforations in the cup f, into the chamber formed between this cup and the
deflecting-cone g, and flows through the aperture gl on both sides of the spreader/,
being deflected upon the flame by the said cone g. The flow of the air is
thus concentrated upon the flame, the air being, moreover, heated to some
extent in its passage through the said chainber. I thus produce a kind of
regenerating gas-burner.
By the above described arrangement of the heating chamber, the deflecting-
cone or dome and the spreader, I provide for greatly increasing the illuminating
power of the burner and the steadiness of the flame. And it is evident that Ï
can, if desired, use these devices or attachments with any suitable form of
burner either with or without a regulator.
I provide an ordinary cock or tap for turning on or shutting off the supply
of gas to my improved burner, and a nipple of any desired construction can
be used.
In some cases, I provide, either through the said cock or tap or in any other
convenient manner, a bye-pass to allow a small quantity of gas to pass after the
cock or tap has been closed, for the purpose of supplying a small igniting flame.
My improved burner can be adapted for producing either a bats-wing or a fish-
tail flame as may be desired.
It is obvious that I can somewhat modify the construction of my improved
apparatus without departing from the nature of my said invention. For instance,
the perforated cup, the deflecting-cone or dome and the spreader may, if desired,
be made of other suitable shape.
Moreover I can employ, instead of the annular piston and perforated conical
seating above described, an annular seating and a perforated conical piston arranged
to be moved towards the said seating by the action of the gas and away from the
said seating by gravity. And I can, if desired, fix an ordinary burner in the top of
the cylinder or casing containing the automatic regulator, and dispense with the
said perforated cup, the deflector and the spreader. It is, however, much more
advantageous to use these devices or attachments.
By the employment of the adjusting-screw extending into the interior of the
hollow or tubular stem of the gas-burner, I am enabled to vary the area of the
passage for the gas according to the pressure ordinarily used in the system of gas
distribution to which the burner is applied.
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:-
First. A regulator for a gas-burner, wherein a piston or valve working in a
cylinder is arranged to be moved towards a suitable seating therein by the gas, and
away from the said seating by gravity, substantially as herein before described.
Second. The combination, with the hollow or tubular stem of the gas-burner, of
an adjusting-screw extending into the interior of the said stem, substantially as, and
for the purpose, above specified.
Third. A self-regulating burner comprising a cylinder or casing, a perforated
conical seating fixed therein, and an annular piston arranged to work up and down
in the said cylinder or casing beneath the said seating, substantially as described
with reference to the accompanying drawing.
Fourth. The combination, with a gas-burner, of a chamber at the upper end
thereof baving perforations in its underside for the admission of air and having an
aperture in the top thereof for the passage of the flame and of the air heated in the
said chamber, substantially as, and for the purpose, above specified.
Fifth. The combination of the perforated cup, the deflecting cone or dome and
the spreader, substantially as, and for the purposes, above specified.
Sixth. The improved apparatus comprising the regulator, the perforated cup,
the

page_text: deflecting-cone or dome, and the spreader, all constructed substantially as described
with reference to the accompanying drawing for the purposes above specified.
Dated this 7th day of May 1892.
