of Columbia, United States of America, Gentleman ]
An Improvement in Fuel Gas Burners
We, THE GAS PATENTS SYNDICATE LIMITED of 37 Walbrook in the City of
London Manufacturers do hereby declare the nature of this invention to be as
follows
-
This invention relates to apparatus for burning gas as fuel for boilers or furnaces,
in which apparatus a gas induction jupe lends into an air induction pipe having a jet
orifice at which the mixture of air and gis is burned
The object of the invention is to secure, by a simple and convenient arrangement,
a thorough mixture of the air and gas before they issue from the burner, thereby
obtaining complete combustion with convenient means of regulating the supply of
both the air and gas
The construction for this purpose is illustrated by the accompanying drawings
Fig 1 is a view partly in section of a burner according to this invention
Fig 2 is an elevation of a multiple jet pipe which may be applied to the said
burner
Fig 3 shews in section one form of reducer for use on the burner
A is the air supply pipe provided with a regulating valve B, an elbow C, beyond
the valve, and, beyond the elbow C, a neck D hitting closely within the collar E, of
a bulb H held by set screws G
The bulb His contracted at its outer end to form a nozzle F of less width than
the air pipe A on which nozzle a jet pipe I which may be of the multiple form shewn
by Fig 2, can be fixed, either directly, or with an interposed reducer of the form
shewn in Fig 3
Through a central ring of cross ribs J and through a boss C on the side of the
elbow Cis passed tightly a gas pipe L, the end of which opens as a jet L' in the
chamber H
The interior of the gas jet L¹ is made larger than the gas pipe, with a trumpet
mouth, and a conical spreader L³, which can be closed as a valve, is fixed on a
spindle L which extends through the pipe L and terminates in a hand wheel O
The spindle is screwed through a nut at P, so that by turning the hand wheel O,
the spreader L can be adjusted to and from the mouth of the jet L' When it is
more or less open it acts in conjunction with the trumpet mouth, to deflect the
Issuing current of gas outward on all sides within the chamber H, and thus causes
the gas to be intimately mixed with the air passing through the chamber to the
contracted nozzle F
The gas pipe L is connected as shewn, with a gas supply pipe Q provided with a
regulating valve R
By properly adjusting the gas and air supply valves R and B, and the gas
spreader with relation to each other, a flame of greater or less power may be
obtained at the burner jet F with complete combustion of the gas

An Improvement in Fuel Gas Burners
We, THE GAS PATENTS SYNDICATE LIMITED of 37 Walbrook in the City of
London, Manufacturers, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascertuned
in and by the following statement
-
This invention relates to apparatus for burning gas as fuel for boilers or furnaces in
which apparatus gas induction pipe lends into an ur induction pipe having jet
orifice at which the mixture of air and gas is burned
The object of the invention is to secure by a simple and convenient arrangement,
a thorough mixture of the ur and gas before they issue from the burner thereby
obtaining complete combustion with a convenient means of regulating the supply of
both the air and gas
The construction for this purpose is illustrated by the drawings accompanying the
Provisional Specification
Fig 1 is a view partly in section of a burner according to this invention
Fig 2 is an elevation of a multiple jet pipe which may be applied to the said burner
Fig 3 shews in section one form of reducer for use on the burner
A is the air supply pipe provided with a regulating valve B, an elbow (, beyond
the valve, and, beyond the elbow C, with a neck D, fitting closely within the collar E,
of a bulb H, held by set screws G
3
The bulb His contracted at its outer end to form nozzle F of less width than the
air pipe A on which nozzle a jet pipe I which may be of the multiple form shown can
be fixed either directly or with interposed reducers of a form such as is shown in
Figure 3
Through a central ring of cross ribs J and through a boss C on the side of the
elbow C, is passed tightly a gas pipe L, the end of which opens as jet L' in the
chamber of H
The interior of the gas jet L' is larger than the gas pipe, with a trumpet mouth,
ind a conical spreader 1 which can be closed as a valve, is fixed on a spindle L³,
which extends through the pipe 1, and terminates in a hand wheel O
The spindle L³ is scre ved through a nut at P, so that by turning the hand wheel O,
the spreader L can be adjusted to and from the mouth of the jet L¹ When it is
more or less opon it acts, in conjunction with the trumpet mouth, to deflect the
issuing current of gis outward on all sides within the chamber H, and thus causes the
gas to be intimately mixed with the air passing through the chamber to the contricted
nozzle F
The gas pipe L is connected as shewn with a gas supply pipe Q, provided with a
regulating valve R
By properly adjusting the gas and air supply valves R and B, and the gas
spreader with relation to each other, a flame of greater or less power may be
obtained at the burner jet F with complete combustion of the gas
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed we declare that what we
claim is
-
1 The combination, in a fuel gas burner, of a valved air induction pipe provided
with an elbow, a mixing chamber with jet orifice, a gas pipe lending through the
side of the elbow and opening within the mixing chamber, spindle adjustable
longitudinally in the gas pipe, a spreader valve fixed on the spindle over the end
of the gas pipe and a valved main gas supply pipe, substantially is described
2 The bulb H enclosing the gas spreider ind forming a mixing chamber for
the gas and air substantially as described
