Improvements in Gas Stoves.
I, JOHN ELLISON DAME, residing at 435 Bedford Avenue in the City of Brooklyn,
in the County of Kings, and State of New York, United States of America, Fire
Insurance, do hereby declare the nature of this invention to be as follows:-
This invention relates to gas stoves, and particularly to that class thereof which
are designed for heating purposes; and the object of the invention is to provide an
effective heater of this class in connection with which is employed a water circu-
lating apparatus or means for employing either water or steam as an aid or auxiliary
in producing the required heat; a further object being to combine a gas heater
which employs radiators, and a circulatory apparatus for water, a hot air drum
into, and through which the products of combustion are passed, and through which
also extends air tubes, which serve as auxiliary means for heating the air in the
compartment, dwelling or building in which the heater is employed, and with this
and other objects in view, the invention consists in the construction, combination
and arrangement of parts hereinafter described and claimed.
In the practice of my invention I provide an oblong fire box which is preferably
rectangular in cross section, and square or approximately so, and near the bottom
of this fire box and at each side thereof, are arranged two longitudinal plates,
between which the burner is placed, and said burner consists of a longitudinal
box or housing composed of two vertical side plates, a bottom plate formed
integrally with the vertical side plates, and a top plate which is semi-circular in
form in cross section, and which is preferably formed integrally with the vertical
side plates, and said burner is removable from the fire box, being capable of being
slid out at the end thereof, and the object of this arrangement is to provide means
for repairing the burner or cleaning the same.
Each end of the fire box is provided with a removable head, and said heads are
provided with internal chambers, and passing longitudinally through the fire box
are circulating pipes which communicate therewith, and one of said heads is carried
downwardly below the bottom plate of the burner, while the other terminates
above the burner proper, and communicating with the upper portion of the last
named head is an elbow pipe which extends upwardly, and the upper end of which
communicates with the lower end of the adjacent side tube of a radiator mounted
on the fire box, and communicating with the bottom of the head at the opposite
end is a tube which communicates with the adjacent side tube of the radiator,
and which is provided with an upwardly directed extension in which is placed a
glass or other transparent plate, the object of which is to provide means for
determining the height of the water in the circulating apparatus.
. The heads at each end of the fire box communicate with the said tubes of the
radiator on the same level, and each of said radiator tubes is placed in communica-
tion by means of pipes or tubular coupling heads, said coupling heads or pipes being
arranged in line with the communication of the heads with the side tubes of the
radiator.
The fire box is provided with a backwardly directed extension formed by extend-

page_text: ing the top plate of the fire box, and by a bottom plate secured to the fire box or
formed thereon, and extending vertically through said extension are a number of
short pipes which open between the rear portion of the radiator tubes, said radiator
tubes being preferably oblong in form in cross section, and secured to the rear
portion of the extension is an air drum which communicates with said extension
throughout its length, and passing vertically through said air drum are a number
of air tubes which extend downwardly through the bottom of said extension, and
through the top plate of the drum.
I also employ an escape flue or pipe which communicates with the air drum
by means of an elbow or any other desired connection, and this elbow or connection
is preferably arranged near the bottom of said drum, and at the back thereof,
and in the bottom plate of the extension of the fire box is formed a passage or open-
ing which communicates with a chamber or receptacle with which communicates
a trap pipe, the object of this arrangement being to provide means for the escape
of water, or gas and water, which collects within the drum.
The burner of my improved heater is adapted for using gas, or gas and air, and
for this purpose an ordinary Bunsen burner may be employed, and I also employ
a removable plate which is secured to the end of the fire box, through which the
pipe for supplying gas, or gas and air passes, the object of this removable plate
being to provide means for the removal of the burner, and in connection with said
plate I also employ a pilot which forms a part of the air and gas mixing apparatus
and below said removable plate are openings through which air may be admitted.
I also form the heads of the fire box so that they may be removed therefrom,
and the water ma- be passed into the circulating apparatus through the upwardly
directed extension, of the tube connected with one of the heads, said extension being
provided with a removable cap for this purpose, and I also place a transparent
plate in the outer side of the fire box through which the condition of the burner
may be determined.
In practice, the circulating apparatus is filled with water up to and slightly
above the points where the heads of the fire box communicate with the radiator,
and when the water has been heated, it will circulate as will be readily understood,
the circulation being similar to that of other apparatus of this class, and the pro-
ducts of combustion pass into the air drum, and around the various air tubes, and
passages, and by means of the arrangement of the various air tubes and passages
almost the entire amount of heat is extracted from the products of combustion,
or hot gases from the fire box, and I am thus enabled to utilize the entire amount
of heat produced by the combustion of the combined gas and air, and also at the
same time to provide means for the escape of the noxious gases that are produced
by the combustion of gas, and I thus provide a simple and effective heating
apparatus which is comparatively inexpensive, and which may be utilized in
almost any compartment, room, office or structure.

COMPLETE SPECIFICATION.
Improvements in Gas Stoves.
I, JOHN ELLISON DAME, late of 435 and now residing at 977 Bedford Avenue,
Brooklyn, in the County of Kings, and State of New York, United States of
America, Fire Insurance, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-

page_text: This invention relates to gas stoves, and particularly to that class thereof which
is designed for heating purposes; and the object of the invention is to provide an
effective heater of this class in connection with which is employed a water circu-
lating apparatus or means for employing either water or steam as an aid or auxiliary
in producing the required heat; a further object being to combine a gas heater
which employs radiators, and a circulatory apparatus for water, a hot air drum
into and through which the products of combustion are passed, and through which
also extends air tubes, which serve as auxiliary means for heating the air in the
compartment, dwelling or building in which the heater is employed; and with these
and other objects in view, the invention consists in the construction, combination
and arrangement of parts hereinafter described and claimed.
The invention is fully disclosed in the following Specification, of which the
accompanying drawings form a part, in which-
Fig. 1, is a sectional front view of my improved heater, the lower portion thereof
being in vertical section, so as to better show the construction of the burner and
the air circulating apparatus and the connection thereof with the radiator tubes;
Fig. 2, a sectional end elevation showing the burner, the fire box, and the air
drum in section, and showing also the communicating passage or passages between
the fire box and the air drum and the drainage pipe or trap connected with the
air drum; and,
Fig. 3, is a perspective view of the device or heater with the radiator proper
removed.
In the practice of my invention I provide an oblong fire box A, which is prefer-
ably rectangular in cross section and square or approximately so, and near the
bottom of this fire box and at each side thereof are arranged two longitudinal
plates a, between which the burner B is passed, and said burner consists of a
longitudinal box or housing composed of two vertical side plates b, a bottom plate bl,
forined integrally with the vertical side plates b, and the top plate B, which is
semicircular in form in cross section and which is preferably formed integrally
with the vertical side plates b, and said burner is removable from the fire box
being capable of being slid out at the end thereof, and the object of this arrange-
ment is to provide means for repairing the burner or cleaning the same whenever
necessary.
At one end of the fire box is a removable head C and at the other a removable
head D), and said heads are provided with internal chambers with which the circu-
lat ng pipes E communicate, and, as will be observed, the head D is carried down-
wardly to the bottom plate of the burner, while the head C terminates above the
burner proper, and communicating with the upper portion of head C is a pipe F,
the other end of which communicates with the lower end of the adjacent side
radiator tube, as shown at f, and communicating with the bottom of the head at
the opposite end is a tube G, the upper end of which is provided with a vertical
extension 9, the upper end of which communicates with the adjacent side radiator
tube by means of a pipe g', and placed in the outer side of the extension g at g
is a glass or other transparent plate, the object of which is to provide means for
determining the height of the water in the circulating apparatus, as will be here-
inafter described.
It will be observed that the head C and the head D communicate with the
radiator tubes H on the same level and each of said radiator tubes is placed in com-
munication by means of pipes or tubular coupling heads h, as clearly shown in
Fig. 1, said coupling heads or pipes being arranged in line with the pipes F and g²,
as is also clearly shown in said figure. Projections H2 are formed on the tubes H
to regulate their distance apart.
The fire box A is provided with a backwardly directed extension K, formed by
the ton plate k, which also forms a top plate of the fire box, and the bottom plate ki,
which is secured to or formed on the back plate of the fire box, and extended
vertically through said extension are a number of short pipes L, which open
between the rear portion of the radiator tubes H, said radiator tubes H being pre-

page_text: ferably oblong in form in cross section, and secured to the rear portion of the
extension K is an air drum M, which communicates with the extension throughout
its length, as shown at m, and passing vertically through said air drum are a
number of air tubes N, which extend through the bottom plate k¹ of the extension K
and through the cap or top plate m³ of the drum.
I also employ an escape flue or pipe O, which communicates with the air drum
by means of an elbow O¹ or any other desired connection, and this elbow or con-
nection is preferably arranged near the bottom of said drum, and at the back thereof
and in the bottom plate of the extension K is formed a passage or opening P,
which communicates with a chamber or receptacle P, with which communicates
a trap pipe P³, and the object of this arrangement is to provide means for the escape
of the water within the drum M.
In operation gas and air combined are employed, said gas and air being admitted
into the burner through a pipe R by means of an ordinary Bunsen burner, (not
shown) or by means of any preferred device, and I also employ a removable plate S,
which is secured to the end of the fire box, through which the pipe R passes, the
object of this removable plate being to provide means for the removal of the
burner, and in connection with said plate I also prefer to employ a pilot or guide,
which forms a part of the air and gas mixing apparatus, (which is not shown for
the reason that it forms no part of this invention,) and below the plate S are
openings S, into which air passes beneath the plates a of the fire box, said plates a
being provided with perforations a, whereby said air passes into said fire box
and around the perforated burner.
I also prefer to form the heads C and D so that they may be removed from
the fire box, and my invention is not limited to the form and construction of said
heads or to the number of circulating tubes E which are employed, or to other
features of the construction herein shown and described, and I therefore reserve
the right to make all such alterations therein and modifications thereof as fairly
come within the scope of the invention.
In practice the upper portion of the extension 9 of the tube G is provided with a
cap or cover U, which may be made removable, through which the water is passed
into the circulatory apparatus or into the head D, and I also prefer to provide
transparent plates W in the outer side of the fire box, through which the condition
of the burner may be determined.
In operation the heads C and D and the pipes E are filled with water through
the extension by removing the cap or cover U, and enough water is employed
to fill said heads and said pipes and the coupling pipes F and g' and the radiator-
pipes or sections up to or slightly above said coupling pipes, and when the gas and
air has been ignited and the water heated said water will circulate, as will be readily
understood, the circulation being through the pipes E, the head C, the coupling
pipe F, through the lower portions of the radiator sections or tubes, and downwardly
into the lower portions of the head D, and this circulation, as will be understood
will be kept up as long as the heater is in operation.
It will also be understood that the products of combustion pass into the drum M,
and at the same time said products of combustion pass around the tubes L, through
which air passes into the spaces between the radiator tubes or section H, and at the
same time air, passes into the tubes N from below upwardly, and by means of this
arrangement almost the entire amount of heat is extracted from the products of
combustion, and the coupling elbow or section O¹ is never at any time heated to
any considerable extent, and by means of this arrangement I am also enabled to
employ a flexible tube O, through which the products of combustion may be passed
into the escape flue or chimney or out. through the window or any other desired
passage that may be provided.
In this apparatus there will be a constant condensation within the air drum M,
and although this condensation is slight I provide means for the escape thereof
consisting of the receptacle P³, the trap P³, and an ordinary goblet cup, or other
receptacle may be placed under said trap for the reception of said condensation.

page_text: By means of this construction I am able to utilize the entire amount of heat pro-
duced by the combustion of the combined gas and air, and also to provide means
for the escape of the noxious gases that are produced by the combustion of gas,
and I thus provide a simple and effective heating apparatus which is comparatively
inexpensive and which may be utilized in almost any compartment, room, office,
or other structure.
