ROBERT NEVILLE, of Butleigh Court, Glastonbury, in the County of Somerset.
'IMPROVEMENTS IN KITCHEN RANGES."
This Invention has for its object improvements in kitchen ranges.
For this purpose I adapt a steam boiler so that it can be used separately or in
conjunction with the hot plate and ovens, the steam to be used for cooking and for
warming rooms when desired. To do this there is a flue or tubes through the side
of the fire-box, through which on opening a damper the heat passes, and thence
under the hot plate; or by shutting the fire and ash pan doors of the boiler, which
are made good fits to exclude air, the fire from the hot plate is made to pass
through the boiler; or by shutting the side damper the boiler can be worked by
its own fire in the ordinary way.
The steam boiler is preferably of cylindrical form, and is set vertically by the
side of the range.
The ovens are placed one over the other, the heat being made to pass equally all
round them by proper holes made in the plates, which divide the flues; these plates
can slide out, so that the soot on the ovens and flues can be easily and properly
cleaned.
The boiler for hot water circulation is preferably cylindrical in form and
horizontal; it is placed between the range fire and ovens, one end of the boiler
coming flush with the front of the range. In this end is placed the man hole, so it
is much easier to get at to clean than most kitchen boilers, and by disconnecting
the flow and return pipes, the boiler can at once be slid out of its seat and replaced
without removing brickwork. The fire is led round the boiler by flues, and
through it by ordinary boiler tubes. The flue or chimney from the steam boiler
can also be made available for heating the water, by means of a water jacket round
it made of boiler tube.
The apparatus can be made without the circulating hot water boiler, and is.
entirely self contained, the flue from the ovens on one side, and from the boiler on
the other, being connected and led away into the ordinary chimney.
The waste steam from the safety valve of the steam boiler is led into a tank in
which it is condensed, whence pure water can be taken for tea or other purposes,
a great convenience where hard or impure water only is obtainable.

more fully the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front elevation; Figure 2, a vertical longitudinal section, and
Figure 3, a plan view of a kitchen range constructed according to my Invention.
A is a vertical steam boiler with an internal fire box B, from the top of which rises
a vertical flue C in the ordinary manner; D is a flue through the sido of the fire
box leading into the flue below the hot plate E of the range; F is a damper by
which the passage through the flue D can be opened or closed; G is a fire grate
under the hot plate; H is a cylindrical boiler placed horizontally at the side of the
range fire G. One end of the boiler comes flush with the front of the range, and in
this end is a man-hole I. The fire is led around the boiler by flues, as shewn;
K, K, are ovens placed one over the other with flue spaces between them; L, L, aro
plates which divide these flues; in the centre of these plates are holes M to cause the
heat to pass equally around all the ovens. The plates L can be drawn out sidewise,

page_text: and when drawn out leave wide openings, so that soot can easily be cleaned off
from the top of the ovens; N, N, are the dials of pyrometers which may be used
for indicating the temperature of the ovens.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that I claim,―
First. The combined arrangement of kitchen range, substantially as described
and illustrated in the Drawing annexed.
Second. The combination of a steam boiler and kitchen range, substantially as
described, so that the boiler may be used for heating the hot plate and ovens of
the range, or the range fire used for heating the steam boiler, or the and
steam boiler be each heated by their own fires.
range
Third. The combination with a kitchen range of a horizontal boiler of circular or
other form in cross section, and with one end flush with the front of the range, for
the purpose described.
Fourth. The arrangement of ovens one above the other with flues between, and
with the partition plates which divide these plates made capable of being drawn out
sidewise through wide openings, for the purpose described.
In witness whereof, I, the said Robert Neville, have hereunto set my hand
and seal, this Nineteenth day of March, in the year of our Lord One
thousand eight hundred and eighty-one.
