GEORGE EDWARD SWALLOW, of Swansea, in the County of Glamorgan, Engineer.
"IMPROVEMENTS IN HEATING OR WARMING STOVES." [A communication from
abroad by Messrs. D. Moore and Company, of Hamilton, Ontario, Canada.]
According to the present Invention a heating or warming stove is constructed as
follows: Within the lower part of a casing is a chamber surrounded by an air
space, and containing a circular fire-grate supported upon pivots in such manner
that it can both be tilted up and down and turned on its centre.
Below this grate
an ash-pit is formed in the chamber, the bottom of such ash-pit being at some
distance from the base of the casing. Above the grate is a receptacle open at top
and bottom, with the sides sloping inwards somewhat towards the lower end, which
approaches to within a short distance of the grate, and which is formed with deep
serrations. This receptacle, together with the grate forming the bottom thereof,
constitutes the fire-box, the fuel being fed into it from a vertical feeding cylinder of
some length fitted within the upper part of the casing, so that an air space inter-
venes between the two all round, the feeding cylinder and casing being closed by a
cover at top. The lower end of the feeding cylinder is also made with its side
sloping inwards somewhat. On the one side of the casing at a level with the upper
part of the fire-chamber is a branch pipe, which is connected to the chimney flue,
and which can be closed by a slide or damper. Upon the top of this branch is
provided an aperture, into which is fitted an evaporating pan containing water.
communication is also established between the space at bottom of the casing and
the said branch at a point beyond the damper of the latter by means of a passage
formed in the casing..
A
A door with regulating slide is provided in the casing at the level of and commu-
nicating with the ash-pit for the ingress of air and for removing the ashes, and
opposite this a regulating slide or damper is provided in the side of the inner chamber

page_text: just below the grate, this slide being adjusted by means of a rod passing through
the side of the outer casing.
Other doors are provided, firstly, on a level with the top of the fire-grate, and,
secondly, on a level with the top of the fire-box; these doors are by preference
formed with mica panes so as to see the fire through them, and on opening them
the fire can be stirred with a poker, and the grate can be rocked occasionally on its
pivot to remove the clinkers, or when it is desired to put out the fire; this can be
effected by turning the grate half round, when the fire will drop through into the
ash-pit.
On kindling the fire, and when a lively draught is required, the damper
leading directly into the flue is opened, and the check draught damper below the
grate is closed.
In order to moderate the fire the direct draught damper is closed, and the check
damper is opened.
If desired apertures provided with regulating slides may be formed in the lower
part of the casing, so as to allow a portion of the hot air from the space surrounding
the inner chamber to enter the room.
