PROVISIONAL SPECIFICATION.
Improvements in Fire-grates and Domestic Heating Stoves.
We, WILLIAM HOSGOOD YOUNG WEBBER, of Dunham Lodge, Teddington, Civil
Engineer, and WILLIAM EDWARD PRICE, of Bushey View, Hampton Wick, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
Our improvements consist in an arrangement and combination of parts and
fittings of open-fire grates, fireplaces, or domestic heating stoves for burning solid
fuel. We can construct our firegrate, or stove, partly of metal and partly of
refractory earth or firebrick, in a variety of shapes. The bottom of the firegrate,
or firebars, is made moveable so as to be capable of being rocked or shaken with
the object of riddling out the dust and ashes from the fuel; and also of being wholly
removed to allow the ashes to fall down out of the grate. The front of the
grate is made of bars, preferably vertical, sloping inwards from the bottom towards
the top of the grate, at such an angle that the dust and ashes produced by the
burning of the fuel shall be disposed as much as possible to fall within rather than
without the line of the front of the bottom of the grate. A blower of perforated,
woven, or latticed metal or other incombustible material, forming part of the fire-
place, is arranged to drop or slide over that part of the fireplace over the grate usually
left open to the air. It may be made by any mechanical means to remain
stationary at any height required to cause an increased draught through the bottom
and front of the fire grate. Under the firegrate we place an ashpan which may be
made to stop or check the access of air to the bottom of the fire if desired.

Improvements in Fire-grates and Domestic Heating Stoves.
We, WILLIAM HOSGOOD YOUNG WEBBER, Civil Engineer, of Dunham Lodge,
Teddington, and WILLIAM EDWARD PRICE, Civil Engineer, of Bushey View, Hamp-
ton Wick, both of the County of Middlesex, 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:-
Our invention relates to improvements in fire-grates, domestic heating stoves
and the like, and has for its object to provide means for cleaning the fire from
dust and ashes, means for precluding the fall of fuel from the fire on to the hearth,
and means for the regulation of the combustion of the fire within the grate or stove,
as may be required.

page_text: Our invention consists of a grate having the bottom fire-bars movable for the
purpose of being rocked or shaken to clean the fire from dust and ashes; and having
the front bars inclined inwardly from the bottom to the top so as to provide a
relatively larger space at the bottom of the fireplace than at the top, and having a
perforated latticed or wire gauze draw-plate or blower provided within the canopy
of the grate, and capable of being lowered so as to cover the space above the grate
through which air usually passes to the chimney and thereby regulate the air
supply to the fuel, without obstructing the view of the fire or the radiation of its
heat outward.
Our invention is illustrated in the accompanying drawings, in which
Figure 1 illustrates in front elevation, and
Figure 2 in sectional elevation corresponding thereto a fire-grate provided in
accordance with our present invention.
In carrying our invention into effect, we construct our fire-grate of cast metal and
refractory material in any usual manner, and according to any particular design,
such as that illustrated in the drawings, which represent a drawing room grate A
of plain design.
We provide the bottom fire bars or grid B movable and capable of sliding upon
lateral ledges b, formed upon the sides of the fire grate casing. The front A¹ of the
fire-grate casing A has provided thereupon vertical front fire bars C, having an
inward inclination from the bottom to the top, where they are respectively secured
to horizontal members in turn fixed into the casing, or independently provided and
introduced as a whole within the grate casing. The movable fire bars or grid B is
secured in its home position by means of a pin D, which passes through lugs
respectively provided upon the lower horizontal member of the front
fire-bars, and the movable fire-bars or grid B. Below the fire-grate and
capable of removal therefrom is an ash pan E, which may have an open aperture E¹
in front of the grid B through which air may pass for the combustion of the fuel in
the grate, while above the fire-place, and within the canopy of the grate casing, a
vertical sliding perforated wire gauze or latticed draw-plate or blower F is provided,
of metal or other incombustible material, which draw-plate may be drawn down
and caused to stop at any desired height, so as to cover the open space above the
fire-place for the regulation of the air-supply to the fuel. Grooves f are provided
laterally upon the front A¹ of the fire-grate into which the projecting extremities fl
of the frame of the draw-plate or blower may enter, the draw-plate being adjusted
into the position required by means of a handle G. We do not confine ourselves
to the actual means illustrated for the adjustment of the draw-plate into varying
positions as other equivalent means may be employed having the same effect.
It will thus be seen that in a grate according to our invention the fire may be
cleaned from dust and ashes by the shaking and partial withdrawal of the fire-bars
or grid B; while the formation of the front fire-bars precludes the fuel from falling
on to the hearth, and the draw-plate or blower permits of the effective regulation of
the air through the fuel, and the combustion of the fire, without obstructing the
view of the fire, or the radiation of its heat outward.
We may cover the bottom fire-bars or grid with a plate, or so arrange the separate
fire-bars B that they may close the bottom of the grate altogether except when it is
required to shake the ashes, and for this purpose supplementary fixed fire-bars or
grid may be provided above the movable fire-bars or grid B, or a set of supple-
mentary fire-bars or grid at relatively great distances apart may be provided, so that
the fire may be supported, while the closer pitched movable grid is withdrawn or
shaken.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-

and illustrated.
2. In domestic fire-grates for burning solid fuel the provision of a sliding per-
forated draw-plate or blower provided in the grate casing, capable of adjustment
into any position within the open space above the fire-place, by the means and for the
purpose substantially as described and illustrated.
3. In domestic fire-grates for burning solid fuel the combination of rocking or
removable bottom fire bars or grid, front bars sloping inwards from bottom to top
and a sliding perforated drawplate or blower provided within the grate casing for
the purpose, and substantially as herein before described and illustrated.
