OR STOVE FOR THE BETTER WARMING OF ROOMS OR APARTMENTS.'
"
The nature of our Invention consist of an improved system of fire grate by means
of a, retort formation composed of clay or other suitable material, adapted by its
construction to produce gaseous vapours; also coking the coal used for the purpose
of warmth, causing an economic action of fuel for the dessemination of heat where
required.
In the arrangement of the ordinary or usual kind of grate there is a large space
or area between the top of the actual fire place or grate proper and the commence-
ment of the chimney proper; and also a large area of ash pit beneath the fire place
or grate. Now in this our improved retort grate we prevent a too rapid combus-
tion, and also guard against the heat passing away direct by the current caused by
the chimney by closing in the top and bottom of the grate in the following manner:
-We, firstly, altogether do away with the space or area between the top of the
actual fireplace or grate and the chimney proper and bring the chimney down to the
top of the grate and close the upper part of the latter, leaving only a small space
for the passage of the smoke by means of a pipe passing into the chimney and
conducting the smoke up the same in the usual course.
Secondly. From the outside of the building or from any convenient similar place
we bring air to the retort grate by means of a pipe or conduit, which latter passes
up from the bottom of the ash pit through the back part of the area of the same to
the underside of the fire place or grate. By this arrangement when there is a fire
in the retort grate warm air will pass into the room, and when there is no fire cool
air may be admitted by the same means.
In the fore part of the bottom of this retort grate there is a flap or trap door to
regulate that portion of the supply of air for combustion which is taken from the
room or other place wherein the grate is situated. The grate is provided with an
incline false bottom having the air passages or grating in the front part, while the
hinder part is made by preference of fire brick (or other suitable material), and the
sides, back, and roof of the grate round the chimney pipe are similarly lined with
the same material.

page_text: Also we can adapt our arrangement of retort grate to purposes of warming
adjoining or upper rooms by having a passage of air outside the retorts, which being
warmed by the fire is forced as hot air through pipes into the upper rooms, where
it can be let out or shut off at pleasure by a valve adapted to the purpose.
As in the adaptation of our improved retort stove to the existing fire place
openings there will be a large space at the sides and over the fire place or grate
that will require to be closed or covered in, we purpose and claim utilizing this
space in the following manner :-
We place an iron facing to, the stove, affixing the same to the latter, and this
iron facing we make adaptable for the insertion of glass or other suitable material;
either looking glass may be placed there, or it may be embellished with ornamental
or other artistic work, or it may be used as an album; or, further, it may be con-
.veniently applied to advertising purposes, especially in the case where the retort
stove is in a public room or railway station.
