Improvements in Gas, Oil or other Stoves, and in means for Condens-
ing and Collecting the Products of Combustion.
I, JOHN SLATER of York Terrace, Burslem, in the County of Stafford, Potter,
do hereby declare the nature of my said invention to be as follows:-
-
It consists of a Stove made, by preference, in earthenware, and in which gas,
oil, or fuel is used, and the products of combustion are condensed and collected
before they can escape into the atmosphere, and the heat of which products is
utilised to its fullest extent, and which stove is also characterised by the absence
of any current of cold air, or cooling surface passing through the stove, and by the
entire enclosure of all the parts within the stove body as hereinafter described.
Such stove is constructed substantially as follows:-The outer casing is made,
by preference, of earthenware and of any suitable design, but for the purpose of
illustration I will describe it as about 2ft. 6 inches high and 1ft. wide. With
this stove body I use a lamp, gas jet, or fuel chamber, duly provided with chimney
or flue. The top of this chimney or flue terminates in, or projects into, a chamber
or space in the top part of the stove, and directly above such chimney, and
within the said space, is a box, coil or casing connected to a pipe or tube leading
through the stove top or side to the outer atmosphere.
The said box or casing is also connected to a pipe or tube which extends down-
wards and through the wall of the said space to a point in, or near, the base of
the stove, and which, at such point, is open to the stove interior.
The action is as follows:-The products of combustion given off by the lamp
ascends into the space aforesaid, and impringe against the box or casing, and
so heat the air within such box, which immediately sets up a sufficient draught
therein as to cause, or induce, the products of combustion to pass over the top
edge of the wall or walls of the said space, and to descend to the lower part of the
stove, and there enter the open end of the tube or pipe aforesaid, pass up such tube,
and through the box to the outer atmosphere.
In such way I get a stove without any outside current of air passing through it,
and with all the tubes or pipes entirely enclosed within the stove body.
The improved stove may take any suitable outward shape or design, and two
or more lamps may be used therewith, or other variations be effected without
departing from my invention.

densing and Collecting the Products of Combustion.
I, JOHN SLATER of York Terrace, Burslem, in the County of Stafford, Potter,
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:-
It consists of a stove made, by preference, of earthenware in which gas, oil or
fuel is used, and the products of combustion are condensed and collected before
they can escape into the atmosphere, and the heat thereof utilised to the fullest
extent, and which said stove is characterised by the absence of any current of
cold air, or cooling surface passing through the stove for inducing a draught (as
in existing stoves), and by the entire enclosure of all the working parts or fittings
within the stove body as hereinafter described.
And in order that my said invention may be more readily understood and
carried into practical effect, I have hereunto annexed a sheet of drawings, and
will now proceed to describe the same with the figures and letters of reference
marked thereon.
.
Fig. 1 is an exterior elevation of my improved stove, Fig. 2 a vertical section
on line a-b, and Fig. 3 a horizontal section on line e-d. Fig. 4 illustrates a
modification.
In accordance with my invention the body of the stove is, by preference, com-
posed of earthenware, with suitable surface or exterior decoration, and, according
to one modification, of a tripod construction, as shewn in Figs. 1, 2 and 3, with
rounded base (A), supporting three hollow pillars (B), terminating in and support-
ing the upper bowl-like part (C).
Within the tripod construction (B), I place the oil lamp (D), with chimney or
flue (D), which terminates at the entrance of opening (C) of the upper part (C).
Within the said upper part I arrange a box or casing (E), to which is connected
a series of pipes (F), each of which extend down one of the hollow pillars (B)
into the base (A). To such box is also connected the pipe (F) which extends
through the cover (C³) into the outer atmosphere.
The action of the stove is as follows:-The lamp being lit the products of com-
bustion ascend into the upper compartment .(C), and in their passage impinge
and play against, and around, the box (E). In so doing they heat or rarify the
air within the said box, and cause a draught to pass through such box and its
several tubes, thereby inducing a current through the stove and causing the said
products to descend into the base (A), and from thence find their way up the said
tubes and through the box (E), and pipe (F¹) to the outer atmosphere.
Owing, however, to the extended traverse and to the cooling effect of the
earthenware, the said products are robbed of their heavier particles, and to a
largo extent condensed, and the hydro-carbon, etc, is collected in the base (A),
from whence it is periodically withdrawn through the outlet (A¹), or through
which it drains into a loose tray placed beneath.
In such way I produce an efficient condensing stove, and one with which there
are no external fittings, or any current of air introduced through the back or rear
portion of the stove (as in existing stoves) for inducing the draught.
Whilst I have shewn the box (E) it is not essential to the perfect working of
my invention, and I may simply group the pipes (F) in a cluster, as shewn by the
dotted lines in Fig. 2, or I may arrange them as a coil, or in any suitable way

page_text: which will allow the heat given from the lamp to impinge against them, and pro-
duce the desired draught.
In Fig. 4 I shew another form of my improved stove, suitable for use against a
wall, with the outlet pipe slightly coiled to come over the lamp and form the
equivalent of box (E). Whilst I prefer to apply the air tubes in metal I may,
with some forms of stoves, provide for the same being formed in the earthenware.
Having thus particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I wish it to be under-
stood that I do not confine myself to the shape or design of stove, or to the precise
mode of adapting the internal fittings, since the same may be varied without
departing from my invention, and what I claim is:--
1: A stove in which the products of combustion play upon an enclosed box
on pipe communicating respectively with the interior of the base of such stove
and with the outer atmosphere, and by which a draught is produced through said
stove as and for the purposes set forth.
2: A condensing stove as herein described and shewn in Figs. 1, 2 and 3 of
the accompanying drawings in combination with casing (E), or its equivalent,
pipes (F), and pipe (F) mounted and operating substantially as set forth.
3: The stove body shewn in Fig. 4 in combination with pipe (F), or its equiva-
lent, as set forth.
