PROVISIONAL SPECIFICATION.
An Improved Method of Constructing Gas Stoves.
I, THOMAS BATTY, of Balmoral Villas, Colchester, Independent Minister, do hereby
declare the nature of my invention to be an improved method of constructing gas
stoves with atmospheric burners, and my object is to obtain an increased amount of
radiant heat from a small supply of gas with more perfect combustion, by heating
the mixed gas & air in a suitable mixing chamber & to increase the volume of the
gases before ignition by the dilatation of heat.
As at present constructed gas stoves with atmospheric burners allow the mixed
gases to pass as rapidly as possible to the points of ignition. But under my improved
method the united gases are detained in a mixing chamber where they are subjected
to a fierce heat. In this chamber the gases are dilated or expanded to three or four
times their volume. By this means the air & gas are more perfectly mixed &
consumed, and no effluvia arises from the escape of unburnt gas, and a great addition
is made to the radiant heat given off from the surface of the stove.
I construct a mixing chamber with an inch & quarter tube passing up from the
bottom almost to the top of the chamber which may be made of iron or firebrick.
Up this straight tube the gas from an ordinary burner is allowed to discharge itself
at full pressure, & carry with it a large amount of air. The mixing chamber is so
placed that when the stove is lighted, all the heat plays upon it, and instantly expands
the gases inside. The continued force of the gas and air current upward, through the
aforesaid upright tube, drives the mixed gases at the top of the chamber to the bottom
where the burners are placed.
The construction of gas stoves on this regenerative principle makes it easy to
convert an ordinary gas fitting for lighting any room, into a powerful heating stove.
I place on the globe gallery or in the globe itself a circular chamber of the kind
already described of firebrick or other material about the size of an ordinary_gas
globe and this acts as a mixing chamber and as a conductor of radiant hent. Or I
construct a stove chamber in the form of a globe-cover to remain always over the
gas globe, to serve as a reflector when used for lighting, and connected when used as
a stove by a removable tube to the burner below.
I apply the same principle to the construction of other heating stoves for offices
bed-rooms &c. To produce a cheerful stove for sitting rooms &c. I construct a flab
chamber of the ordinary fire place pattern & make across it three or four horizontal
lines of burners which when lighted up with a suitable incandescent material closely
resembles an ordinary fire grate.
In the same way for cooking purposes the flat upright chamber already described,
is perforated with two or three horizontal lines of burners and forms the side of the
ven or other cooking apparatus.

COMPLETE SPECIFICATION.
An Improved Method of Constructing Gas Stoves.
I, THOMAS BATTY, of Balmoral Villas, Colchester, Essex, Independent Minister, 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 object is to obtain the largest amount of radiant heat from a small supply of
gas with perfect combustion by heating the mixed gas & air in a suitable expansion

page_text: chamber, in which the volume of the gases is greatly increased before ignition by the
dilatation of heat.
As at present constructed gas-stoves with atmospheric burners allow the mixed gas
and air to pass as rapidly as possible to the points of ignition. But in my improved
method the united gases are detained in a mixing expansion chamber, where they are
subject to a fierce heat, and dilated or expanded to 2 or 3 times their volume. By
this means the gases are more perfectly mixed and consumed, and a great addition is
made to the radiant heat given off from the surface of the stove, while the escape of
unburnt gas & poisonous fumes is prevented.
I construct a mixing chamber A. A. with an inch & quarter tube B, passing up
from the bottom almost to the top of the chamber, which may be made of fire claymetal
or other suitable material, and up this straight tuhe B, the gas from an ordinaryburner
passes at full pressure carrying with it about nine times its volume of air. The
mixing chamber (A) is so placed that when the stove is lighted all the heat plays on
the external surface and instantly expands the gases contained within. The continued
upward current of gas & air in the tube B, drives the mixed gases at the top of the
chamber to the bottom where the burners C. C. are placed.
The construction of gas-stoves on this regenerative principle makes it easy to
convert an ordinary gas fitting for lighting a room into a powerful stove for warming
it. I place on the globe gallery of a gas-pendant or bracket a round chamber
(A. A, Fig. 1) of the kind already described made of fireclay metal or other material &
this serves the purpose of a regenative expansion chainber and a conductor of
radiant heat. Or I construct a stove chamber in the form of a globe cover to remain
always on the gas-globe & which serves as a reflector when the burner is used for
lighting and is connected by a removable tube to the nipple wlien used as a warming
stove.
I apply the same principle in the construction of other heating stoves or Gas
Fires for offices, bedrooms &c. I construct a narrow upright chamber (A.A.) as shown
in drawing No. 2 with three or four horizontal lines of burners (C.C.) which when
lighted up with a suitable incandescent material closely resembles an ordinary fire-
grate. For Cooking Stoves a similar upright chamber is used of any suitable shape
and perforated with two or three lines of burners which run right across or round
the sides of the oven or other cooking apparatus.
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 construction of an atmospheric gas-slove of globular or other shape easily
attached like an ordinaryglobe to any gas fitting, and having a regenerative expansion
chamber placed above & in contact with the burners, for the purpose of heating and
warming rooms, substantially as herein described & shown upon the drawings.
2. The application of the same mode of construction to other Gas-fires, and to all
kinds of gas-heating and cooking stoves, by placing a regenerative expansion-
chamber in contact with & above the burners substantially as herein described and
shown on the drawings.
