Improvements in Gas-stoves.
I, JAMES HOPKINS CARRINGTON, of 52, West 22nd Street, New York, Merchant, do
hereby declare the nature of this invention to be as follows:-
My invention consists of a stove, the body of which is composed of perforated
metal, designed for burning, to the best advantage, illuminating or non-illuminating
gas. By my invention, I obviate all centralization of draughts or currents of air or
heat, and the heat is given free outward radiation at all points so that there are no
jets of air drawn in at the base and no chimney-like effect above the burner which
results from confining the heated air as with common stoves of this class.
The invention also consists of the combination, with the body of the stove made of
foraminated sheet metal or woven wire, of a cone-shaped shell or dome formed of
transparent material and placed within the body to reflect the light received from below
through the foraminated body of the stove from all sides.
The base of the stove may be of one single casting with legs and flanged to receive
the lower end of the body and the bottom plate which is also perforated. The body
is of sheet iron preferably, and may be from one foot to three or more feet in height.
The perforations are by preference small and close together, from one hundred to three
hundred perforations to the square inch producing the best results. The top may be
without apertures and serve to intercept the rising currents of heated air and to cause
them to be deflected downwards and outwards or in place of this top I may use a
reflector. The burner is located at or near the base of the stove. There is practically
no draught into the stove except at the bottom through the perforated bottom plate.
For high stoves, a perforated plate is preferably placed about centrally of the height
of the stove and held in place by friction strips bearing against the wall of the stove
or by other means, the object of this plate being to deflect the heat and throw it out
more at the base of the stove and to intercept any upward draughts.
Within the casing there is a transparent shell shaped preferably either like a
truncated cone or a rounded dome and open at its top and bottom. This shell is
supported from the inner walls of the outer casing either upon lugs projecting from
the casing or upon hooks attached thereto or by a chain from the top or cap. The
shell is constructed something after the manner of an illuminated lamp shade with
rich transparent coloring. It may be made of mica, porcelain, or colored glass, or it
may be of fine gauze wire with illuminated pannels of mica or colored glass, or it may
be made of two layers of fine and almost invisible gauze wire filled in between with a
layer of broken fragments of colored glass which gives a very brilliant pleasing and
variegated glow. As the light shines upward from the burner, it strikes the inner
wall of this conical or dome-shaped shell and the whole shell becomes illuminated with
glow that is clearly and brilliantly visible through the outer casing from all sides.
This shell also serves an important mechanical function, for, as the hot currents of air
ascending from the burner reach the shell, the contracted passage through it serves to
check or choke the upward passage of air therethrough in a measure and compels a
portion of the heated and expanded air to be forced through the meshes or perforations
of the outer casing below the cone and at a point nearer the floor where the heat is
most to be desired. The remaining portions of hot air pass through the opening at
the top of the cone and, striking the cap, are deflected through the meshes or
perforations of the outer casing above the cone. In this way, the stove is made to
beat uniformly from bottom to top, and excessive heat at the top is avoided, and the
heat is kept down in the lower portion of the room, where it does the most good.

COMPLETE SPECIFICATION.
Improvements in Gas-stoves.
I, JAMES HOPKINS CARRINGTON, of 52, West 22nd Street, New York, Merchant, 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 invention consists of a stove the body of which is composed of perforated
metal designed for burning, to the best advantage, illuminating or non-illuminating
gas. By my invention I obviate all centralization of draughts or currents of air or
heat and the heat is given free outward radiation at all points so that there are no jets
of air drawn in at the base and no chimney-like effect above the burner which results
from confining the heated air as with commom stoves of this class. The top of the
stove is, by preference, closed or imperforate, to deflect the heat outward.
The invention also consists of the combination, with the body of the stove made of
foraminated sheet metal or woven wire, of a cone-shaped shell or dome formed of
transparent material and placed within the body, to reflect the light received from
below through the foraminated body of the stove from all sides.
Reference is to be had to the accompanying drawing, forming part of this
Specification, in which
Figure 1 is a side elevation, and Figure 2 is a sectional elevation, of a gas stove
made in accordance with my invention.
and
Figure 3 is an enlarged view of a small portion of the body of the stove.
Figure 4 is a detailed view of a deflecting plate.
Figure 5 is a vertical section, shewing the reflector.
Figure 6 is a detail of an illuminated reflector applied to the top of the stove,
Figure 7 is a section, shewing a modified mode of constructing the reflector.
Similar letters of reference indicate corresponding parts in all the figures.
The base A of the stove may be of one single casting with legs B and flanged
at a to receive the lower end of the body C and the perforated bottom plate D.
The body C is of foraminated metal, sheet iron preferably, and may be from one
foot to three, or more, feet in height. The perforations are by preference small
and close together, from one hundred to three hundred perforations to the square
inch producing the best results. The top E may be without apertures and serve
to intercept the rising currents of heated air and to cause them to be deflected
downwards and outwards; or, in place of this top, I may use a reflector G, as in
Figure 6, described below. The burner F may be of any approved type and is
located at, or near, the base of the stove. There is, practically, no draught into the
stove except at the bottom through the perforated bottom plate D. For high stoves,
a perforated plate E' is preferably placed about centrally of the height of the stove
and held in place, as shewn, by friction strips e bearing against the wall of the
stove, or by other means, the object of this plate being to deflect the heat and throw
it out more at the base of the stove and to intercept any upward draughts. By this
construction which allows for a full supply of air, I gain thorough combustion and a
full lateral radiation of heat at all parts of the body of the stove.
Within the casing, and supported adjustably at various heights if desired, is a
transparent shell G shaped preferably either like a truncated cone or a rounded dome
and open at its top and bottom. This shell is supported from the inner walls of the

something after the manner of an illuminated lamp shade with rich transparent
coloring. It may be made of mica, porcelain, or colored glass, or it may be of fine
gauze wire with illuminated panels of mica or colored glass, or it may be made of two
layers of fine aud almost invisible gauze wire filled in between with a layer of broken
fragments of colored glass, as in Figure 7 which gives a very brillant pleasing and
variegated glow. As the light shines upward from the burner it strikes the inner
wall of this conical or done shaped shell, and the whole shell becomes illuminated
with a glow that is clearly and brilliantly visible through the outer casing from all
sides. This shell also serves an important mechanical function, for, as the hot
currents of air ascending from the burner reach the shell, the contracted passage
through it serves to check or choke the upward passage of air therethrough in a
measure and compels a portion of the heated and expanded air to be forced through
the meshes or perforations of the outer casing below the cone and at a point nearer
the floor where the heat is most to be desired. The remaining portions of hot air
pass through the opening at the top of the cone, and, striking the cap E, are deflected

the stove is made to heat uniformly from bottom to top, an excessive heat at the
top is avoided, and the heat is kept down in the lower portion of the room where it
does the most good. I may apply the illuminated shell to the top of the outer casing,
as shewn in Figure 3, instead of the middle portion.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. As a new article of manufacture, a gas stove, consisting of a base, a hollow
body portion mounted on the base and having small interstices or perforations extending
substantially to its lower end, and a burner within the body portion and near the lower
end thereof, substantially as set forth.
2. As a new article of manufacture, a gas stove, consisting of a base, a burner, a
hollow body portion, enclosing the burner, mounted on the base and having small
interstices or perforations extending below the normal level of the flame of the burner,
substantially as set forth.
3. As a new article of manufacture, a gas stove, consisting of a base, a hollow
body mounted on the base and having small perforations or interstices extending
substantially to its upper and lower ends, a burner within the body portion near the
lower end thereof, and a cap closing the upper end of the body, substantially as
set forth.
4. As a new article of manufacture, a gas stove, consisting of a hollow body closely
perforated or intersticed throughout its length, a supporting base, a perforated or
intersticed bottom for the body, a burner within the body adjacent to the upper
side of said bottom, and a cap closing the upper end of the body, substantially as set
forth.
. As a new article of manufacture, a gas stove, consisting of a base, a hollow
body portion mounted on the base and having small perforations or interstices
extending substantially to its lower end, a burner within the body portion near the
lower end thereof, and a transverse deflector within the body above the burner,
substantially as set forth.
6. In a gas stove, the combination, with a foraminated or woven wire casing and
a subjacent burner, of an illuminating shell placed above the burner within the
circumference of the casing, substantially as shewn and described.
7. A gas stove, having above the burner an illuminating shell surrounded by an
outer casing of foraminated sheet metal or woven wire, substantially as shewn and
described.
8. In a gas stove, the combination, with a foraminated or woven wire casing and a
subjacent burner, of a cone-shaped or converging shell having its larger end at the

page_text: bottom and resting upon the outer casing at, or near, its middle, substantially as shewn
and described.
