Improvements in and relating to Gas and other Stoves.
I, GEORGE WALLACE, of 17, Claremont Park, Gateshead, in the County of
Durham, Engineer, do hereby declare the nature of this invention to be as
follows:-
-
My invention relates to gas and other stoves or fires for heating purposes and
has for its object to provide a stove grate or receptacle which shall absorb and
retain the heat from the fire or gas burners and better distribute same for heating
purposes than heretofore.
According to my invention I form the grate itself or a separate stove for inser-
tion within the ordinary grate in such a manner that the heat from the fire or
gas burners after passing to the top of the stove or through the usual incandescent
blocks or other artificial fuel devices is led down again to the base thereof and
thence up the sides, over the top and out rearwards or upwards to the chimney.
To this end I construct a stove or apparatus in one or more parts of fire-clay,
fire-brick, iron or other suitable material and having a vertical longitudinal
partition forming the back of the grate or part containing the gas burners or fire
winch division is of less height than the top of the grate or formed with an aper-
ture or apertures thereat through which the heated gases can pass and thence
downward between the said partition and the back of the stove, then through an
aperture or passages on either side to the interior of the side walls of the stove or
apparatus which are formed hollow for the purpose, and then upwards and over
the top of the stove which is also formed hollow and from which the heated gases
pass out into the chimney in suitable direction.
The top and sides of the stove may be extended forward beyond the grate and
so arranged that the heated gases or products of combustion are directed towards
the front part thereof, and the heated gases may in some cases be directed first
over the top, or down the sides and then up the back and over the top.
Apparatus or stoves such as above described are arranged to fit any ordinary
grate, or the grates themselves may be so formed, and for gas fires suitable
provision is made for burners and the use of artificial incandescent fuel or other
heat retaining devices.
By the use of stoves constructed as above the heat is retained and absorbed by
the sides, top and body of the stove and a greater amount is distributed and given
off to the surrounding atmosphere than with stoves as at present in use.

page_text: J, GEORGE WALLACE, of 17, Claremont Park, Gateshead, in the County of
Durham, Engineer, 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 relates to gas and other stoves or fires for heating purposes and
has for its object to provide a stove, grate or receptacle which shall absorb and
retain the heat from the fire or gas burners and better distribute same for heating
purposes than heretofore.
According to my invention I form the grate itself or a separate stove for inser-
tion within the ordinary grate in such manner that the heat from an ordinary
fire or gas burners after passing to the top of the stove, or through the usual
incandescent blocks or other artificial fuel devices, is led down again to the base
thereof and thence up the sides, over the top and out rearwards or upwards to the
chimney. The gases may in some cases be directed first over the top, down the
sides and then up the back, or first down the sides up the back and over the top.
An apparatus constructed in accordance with my invention is illustrated in
the accompanying drawings in which Fig. 1 is a front elevation of an apparatus
fitted in a stove Fig. 2 a plan partly in section of the apparatus itself, Fig. 3
a section on line A B of Fig. 1. Fig. 4 a back view of the stove in perspective,
parts being removed for showing more clearly the arrangement of the passages
and Figs. 5 and 6 are respectively part sectional plan and sectional side elevation
of a modified arrangement.
The stove or apparatus which may be of firebrick, fireclay, iron or other
suitable material is constructed in one part, or for convenience of access to the
interior or case of manufacture it may be in two parts a, a fitting one within
the other and having suitable distance pieces such as a², a², j, j, and i, herein-after
described, for forming the desired passages and connecting apertures. bis a
vertical longitudinal partition forming the back of the grate or part e containing
the fire or gas burners and incandescent fuel F, as the case may be. This divi-
sion b is of less height than the top of the open grate or part c or is formed with
an aperture or it may be two or more apertures thereat through which the
heated gases can pass and from thence downwards in the spaces between the
partition and the back of the grate or apparatus, then through apertures or
passages e, c, on either side to the interior s', s, of the side walls g, g, which are
formed hollow as shown for the purpose. These apertures e, e, are formed by
removing part of the projections or distance pieces a², a² (see Figs. 2 and 4) which
are formed in one with the back portion d. The gases pass upwards in the
spaces s¹, s to the top T also formed hollow, and from which the heated gases
pass out into the chimney M in a convenient direction. In the form shown in
the drawings the gases pass out at the rear through an aperture h and are directed
thereto by a projecting part or distance piece i curved as shown or of other con-
venient form.
The heated gases may in some cases be directed first over the top, down the
sides and then up the back or first through apertures into the side walls and then
up the back and over the top. Figs. 5 and 6 show an arrangement wherein the
gases are directed as first mentioned, the aperture opening into the hollow
top T instead of into the back. The same figs. also show how the top and sides
of the stove may be extended forwards beyond the grate as at a³, suitable baffle
plates or divisions such as j, j being arranged to direct the gases to the front of

page_text: the extended part or parts. From the top the gases pass down the side spaces s¹, sl
through apertures e, e and into and up through the back space S and out at the
apertures.
A damper such as K may be arranged over or in the aperture h or h¹ for the
purpose of regulating the size of the aperture and it may be operated from the
front of the stove by a handle and rod k or otherwise conveniently.
Apparatus or stoves such as above described are ornamented as desired and.
arranged to fit any ordinary grate or the stoves or grates themselves may be so
formed and for gas fires suitable provision is made for burners and the use of
artificial incandescent fuel or other heat retaining devices.
By the use of stoves or apparatus constructed as above set forth the heat is
retained and absorbed by the sides top and body of the stove and a greater amount
is distributed and given off to the surrounding atmosphere than with stoves as at
present in use.
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. A stove, or a heating apparatus for insertion in a stove or grate, having
hollow back, side walls and top, with apertures, partitions, divisions or distance
pieces so arranged as to direct the heated gases from the fire or gas burners through
the said hollow parts before passing to the chimney substantially in the manner
and for the purposes set forth.
2. The improvements in gas and other stoves consisting in forming the stove
or an apparatus for insertion in a stove, in two or more parts fitting one within
the other and having suitable projections or distance pieces and apertures arranged
substantially as set forth so as to direct the gases in the directions described.
3. For use in combination with a stove or grate of ordinary construction and
form, the several forms of apparatus constructed, arranged and adapted for heating
purposes substantially as set forth and illustrated.
