PROVISIONAL SPECIFICATION left by the said Henry Harris Lake at the
Office of the Commissioners of Patents on the 29th June 1883.
HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings, London, "IMPROVEMENTS IN AND RELATING TO GAS-
BURNERS [a communication to him from abroad by Andrew Burrell Lipsey of
West Hoboken, New Jersey, United States of America]
This invention relates to the construction of gas burners wherein the gas and
air which are supplied to support combustion are heated before arriving at the
point where combustion takes place
The said improvements consist essentially in a gas burner having a downwardly
extending burner tip or downwardly extending burner tips, a flue or passage for
conveying air downwardly to the burner tip or tips, a conduit or conduits for
conveying gas downwardly to the burner tip or tips and a flue or passage serving
to convey away the products of combustion, the last named flue or passage being
arranged inwards of the burner tip or tips and extended a considerable distance
below the same, and all the parts being so combined and organized that a flame
will be caused to burn around the exterior of the lower portion of the last named
Alue or passage, the waste products of combustion will be caused to pass around the
end thereof and into its interior, and in passing away will heat the down-coming
air, and gas before their arrival at the burner tip or tips
Burners embodying my improvement may be supplied with gas of any
suitable kind.
In carrying the said invention into practice I provide a gas chamber, of annular
form into which gas is delivered by a pipe from any suitable source. Passages or

page_text: conduits extend downwardly to a number of tubular arms to a burner tip or a
circular series of burner tips. The gas passes from these arms to the burner tip or
tips; the passages or conduits may be cast of metal in one piece with a sholl and
the chambers and arms may be also formed in the same casting. The burner tip
of annular form is secured in place by being screwed on to the exterior of the
head in which the arms are formed, its internal space being in communication
with the space within the said chamber. The gas issues from apertures in the
lower end of the burner tip. Flanges extend laterally from the shell. To the
exterior of the chamber and flange is fitted a cylindric shell which is provided
with openings near the upper end; air enters these openings and passes down
between the two shells and past the flanges to the burner tip The space between
these shells forms the air flues.
There extends above the chamber a chimney which may consist of a separate
piece of sheet metal or other material fitted to a flange. It forms, in effect, a
continuation of the first shell. This shell extends down within the annular burner
tip and it also either extends below the latter or is provided with a renewable
section of suitable material which extends below the same. I shall preferably
employ a renewable section as I can thus prolong the life of the burner, and in
many cases I shall make it of carbon or magnesia or of any suitable substance
which will become incandescent when heated.
On the lower end of the second shell I provide a holder for a glass globe or
casing which may be of any suitable form. This holder may be of any suitable
form but it will be found advantageous to make it of such character that a tight
fit between it and the globe may be obtained in order that the entrance of air to
them may be avoided. I provide a holder which also constitutes a reflector for
throwing the light emanating from the burner downwardly below the burner.
This holder is screwed on to the exterior of the shell and is provided on the upper
side with a circular rib over which an inwardly turned rim formed on the globe
fits on to form a lap joint. It may be made in sections secured together by screws
in order to provide for introducing it into and removing it from the globe. To
remove the globe from the burner the holder may be screwed off. In lieu of
employing an annular burner tip I may use a number of ordinary round burner
tips and fit one to each of the passages or conduits.
The gas enters the chambers and passes thence through the passages or conduits
to the burner tip where it is consumed. The air necessary to support combustion
enters the first shell and passes thence to the lower end of the burner tip.
Owing to the length of the extension of this shell the draft is caused to extend
down into the lower part of the globe. The waste products of combustion pass up
the shell and off through the chimney. The shell forms a flue for the waste
products of combustion. As the waste products of combustion in passing off are
in one side of the shell and the passages or conduits and the incoming air and gas
are separated from them only by the said shell and the walls of the said passages
or conduits, both the air and the gas are highly heated before arriving at the point
where combustion takes place.
The burner can be lighted by taking off the holder and globe or in any other
suitable manner. I may, to facilitate lighting, provide an opening in the holder or
deflector and furnish it with a cover.
Preferably I arrango outside the second shell a shield extending outside the air
inlot apertures and down nearly to the holder. This prevents the air from rushing
violently into the air inlet apertures and hence makes the supply more uniform
than it would otherwise be, "This shield extends from a collar which surrounds the
air inlet apertures. The collar has apertures corresponding to the air inlet
aperture and can be turned to bring the two sets of apertures more or less into
line so as to vary the quantity of air admitted.

HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings London "IMPROVEMENTS IN AND RELATING TO GAS-
BURNERS a communication to me from abroad by Andrew Burrell Lipsey, of
West Hoboken, New Jersey, United States of America.
"
This invention relates to gas burners of the class wherein the gas and air which
are supplied to support combustion are heated before arriving at the point where
combustion takes place.
The said invention comprises a gas burner having a downwardly extending
burner tip or downwardly extending burner tips, a flue or passage for conveying
air downwardly to the burner tip or tips, a conduit or conduits for conveying gas
downwardly to the burner tip or tips, and a flue or passage serving to convey
away the products of combustion, the last named flue or passage being arranged
inwards of the burner tip or tips and extended a considerable distance below the
same, and all the parts being so combined and organized that a flaine will be
caused to burn around the exterior of the lower portion of the last named flue
or passage, the waste products of combustion will be caused to pass around tho
end thereof and into its interior, and in passing away will heat the down coming
air and gas before their arrival at the burner tip or tips.
Burners embodying this improvement may be supplied with gas of any suitable
kind.
In the accompanying drawing
Figure 1 is a central longitudinal section of a burner constructed according to
this invention, and
Figure 2 is a horizontal section of the same on the line xx Figuro 1.
Similar letters of reference indicato corresponding parts in both figures.
A indicates the gas chamber, of annular form into which gas is delivered by a
pipe B from any suitable source. Passages or conduits C extend downwardly
through a number of tubular arms D to a burner tip or a circular series of
burner tips. The passages or conduits may be cast of metal in one piece with a
shell E, and the chambers A and arms D also may be formed in the saino casting.
I have shown a single burner tip T of annular form secured in place by being
screwed on to the exterior of the head, in which the arms D are formed, its
internal space being in communication with the space within the said chamber.
The gas issues from apertures a in the lower end of the burner tip. Flanges b
extend laterally from the shell E. To the exterior of the chamber A and flange b
is fitted a cylindrical shell F which is provided with openings c near the upper
end. Air enters these openings and passes down between the shells E and F and
past the flanges 6 to the burner tip. The space between these shells forms the
air flues.
Above the chamber A extends a chimney G which may consist of a separate
piece of sheet metal or other material fitted to a flange d. It forms in effect a
continuation of the shell E.
The shell E extends down within the annular burner tip, and it also either
extends below the latter or is provided with a renewable section E' of suitable
material, which extends below the same. I preferably employ a renewable section

page_text: as I can thus prolong the life of the burner, and in many cases I make it of carbon
or magnesia, or of any suitable substance which will become incandescent when
heated.
On the lower end of the shell F I provide a holder F¹ for a glass globe or
casing which may be of any suitable form. The said holder may also be of any
suitable form, but it will be found advantageous to make it of such character that
a tight fit between it and the globe may be obtained in order that the entrance of
air may be avoided.
I have shown a holder which also constitutes a reflector for throwing the light
emanating from the burner downwardly below the burner. This holder is screwed
on to the exterior of the shell F and is provided on the upper side with a circular
ribe over which an inwardly turned rim f formed on the globe to form a lap
joint. It may be made in sections secured together by screws in order to provide
for introducing it into, and removing it from, the globe. To remove the globe
from the burner the holder may be screwed off. In lieu of employing an annular
burner tip I may use a number of ordinary round burner tips and fit one to each
of the passages or conduits C.
The gas enters the chambers A and passes thence through the passages or
or conduits C to the burner tip where it is consumed. The air necessary to
support combustion enters the shell F and passes thence to the lower end of the
burner tip.
Owing to the length of the extension E¹ of the shell E the draught is caused to
extend down into the lower part of the globe. The waste products of combustion
pass up the shell E and off through the chimney G. The shell E forms a flue for
the waste products of combustion. As the waste products of combustion in passing
off are inside the shell E and the passages or conduits C, and the incoming air
and gas separated from them only by the said shell and the walls of the said
passages or conduits, both the air and the gas are highly beated before arriving
at the point where combustion takes place.
The burner can be lighted by taking off the holder and globe or in any other
suitable manner. I may, to facilitate lighting, provide an opening in the bolder or
deflector and furnish it with a cover g.

.
Preferably I arrange outside the shell F a shield I extending outside the air-inlet
apertures and down nearly to the holder. This prevents the air from rushing
violently into the air inlet apertures and hence makes the supply more uniforia
than it would otherwise be. This shield extends from a collar J which surrounds
the air-inlet apertures. The collar has apertures corresponding to the air inlet
aperture and can be turned to bring the two sets of apertures more or less into
line so as to vary the quantity of air admitted.
