Improvements in Gas or Oil Heaters or Stoves.
I, HENRY CHARLES STEINHOFF, of West Hoboken, Hudson County, New Jersey,
United States of America, Master Plumber, 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:-
This invention relates to a gas or oil heater or stove which supplies the burner
with heated air, and causes the hot air, while rising in the combustion chamber,
to become thoroughly impregnated with moisture. The invention consists in
the various features of construction fully pointed out in the claim.
In the accompanying drawing:
Fig. 1 is a side elevation, partly broken away, of a gas heater embodying my
invention.
Fig. 2 a vertical section on line 2, 2, Fig. 1.
Fig. 3 a horizontal section on line 3, 3, Fig. 1.
Fig. 4 a plan of the base with plate y, removed.
Fig. 5 is a side elevation, partly broken away, of an oil stove embodying the
invention, and
Fig. 6 a horizontal section on line 6, -6, Fig. 5.
The body of the stove is composed of two concentric shells a, and b, between
which an annular air-space c, is formed which extends entirely around the com-
bustion chamber d, enclosed by the inner shell b. Cold air is admitted to this
air-space or downtake flue c, by upper openings a¹, in the outer shell a, the air
being drawn down the flue and around the lower free edge of the inner shell b,
into the combustion chamber d, so as to thus become heated and to supply the
burner e, located in chamber d, with warm air.
f, is the annular base of the stove, supported upon legs f¹, and having a top-
plate g, upon which the outer shell a, is set. The top-plate g, is provided with
a diametrically extending bridge-piece g', spanning its central opening and con-
stituting a support for the lower notched edge of the inner shell b, so as not to
impede the flow of hot air around such edge. The open-work top h, of the stove
supported on the shells a, b, is provided with a dividing flange h¹, between such
shells and is by bolts i, and nuts 2¹, connected to the bridge g', so that in this way,
all the parts of the stove are properly assembled.

The bridge g, is centrally perforated to admit the elbow of the gas pipe j,
which pipe may be provided outside of the stove with an auxiliary or pilot"
burner, which, when ignited, ignites the main burner, e, through perfora-
tions a, b, in shells a, b.
Below the burner e, there is hung within the base f, a water-pan k, from
which the vapors may freely rise into the combustion chamber d, through the
central opening of the plate g. A filling opening g², in this plate permits. the
water in pan k, to be replenished.
As the burner e, is ignited, it will heat the air in chamber d, and thus induce
a flow of air through openings a¹, down flue c, around the lower edge of shell b.

air and supplying the burner with such heated air. The heat rising in chamber d,
will be impregnated with vapors from the pan k, and the air thus moistened, will
be discharged into the room through the open top h.

In Figures 5 and 6, the invention is shown to be applied to an oil stove. Here
the oil-reservoir l, is secured below the water-pan k, and the latter is provided
with a central tube k¹, to accommodate the wick tube . The stove-body may be
hinged to the base f, at a³, so that it may be thrown back, and has a door a*,
by which the burner is rendered accessible.
It will be seen that in my improved stove, a thorough double heating effect is
obtained, and that the hot air, while rising through the combustion chamber, is
thoroughly saturated with moisture, so that a desirable moist heat is given off.
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
1. A gas or oil heater composed of two shells, forming an inner combustion
chamber and a surrounding air space that communicates with the combustion
chamber at its lower end, the outer shell being provided with air inlet openings
near its upper end, combined with a burner within the combustion chamber, sub-
stantially as specified.
2. A gas or oil heater composed of two shells, forming an inner combustion
chamber and a surrounding air space that communicates with the combustion
chamber at its lower end, combined with a burner within the combustion chamber,
and a water-pan below the combustion chamber and communicating therewith,
substantially as specified.
3. A gas or oil heater composed of two shells, of which the outer one is per-
forated near its upper end, an open-work top above the shells, a base below the
shells, a burner within the combustion chamber formed by the inner shell, and
a water-pan secured within the base and communicating with such chamber,
substantially as specified.
4. A gas or oil heater composed of two shells, of which the outer one is per-
forated near its upper end, an annular base, an open top-plate supported thereon
and having a diametrically extending bridge, a water-pan secured within the
base below the top-plate, an open-work top mounted on the shells, and a burner
within the combustion chamber formed by the änner shell, substantially as
specified.
5. The improved gas or oil heater or stove, substantially as herein shown and
described.
