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:
This invention has for its object improvements in Cooking Ranges for rapidly
boiling water by means of high pressure boiler for Baths Lavatories &c. also for
Baking Boiling and consuming smoke, with a very small quantity of fuel.
In order that this invention may be thoroughly understood I have appended two
sheets of Drawings showing in seven figures the application thereof.
Fig. 1 showing the range closed as when in use.
Fig. 2, vertical, section A horizontal plate with a series of tubes passing through &
projecting on each side of the plate forming baffels.
By this arrangement the air in passing through the tubes becomes heated melts and
ignites the unburnt gases & thus consumes the smoke.
B showing the section of the Boiler.
C showing flue passing through the Boiler.
D showing flue at the back of the Boiler.
E showing a flue passing over the ashpan F and under the fire and up at the back
of the flue D. it is perforated at the top.
By this arrangement the air is drawn over the ashpan into the flue E. it becomes
heated & passes through the holes at the top it meets & ignites the unburnt gases &
thus consumes the smoke.
F showing the ashpan.
G showing the flue at the bottom of the oven.
I. Fig. 4. Showing a cast Iron grating with a series of gills at the back. This
grating has to be placed in the flue C of the boiler, and thus prevents its being
stopped with cinders, also the gills becomes heated to redness & thus consumes the
smoke.
J showing one of the gills.
Fig. 3. vertical section showing the direction the fire takes when the Boiler is in
The fire passes through the flue C of the boiler up the flue D to the flue H
use.

page_text: leading to the top of the oven, it also passes over the top of the boiler to the flue H so
the boiler is surrounded by fire & the water is heated much quicker than with the
present range. As the fire in the prosent range passes through the boiler flue &
straight up the chimney so that most of the heat is lost.
By my arrangement the fire after passing through the boiler flue Cup the flue D to H
it is then taken over the top part of the oven, by this arrangement the baking &
boiling can be carried on at the same time the water is heating in the boiler for the
Bathroom Lavatories &c.
Fig. 6 Sheet 2 showing horizontal section & position of flue H leading over the
top of the oven to the flue K also showing the damper L open when the boiler is
in use.
Fig. 7, showing the damper L closed when the range is being used for cooking.
The fire now passes up the front of the boiler into the consuming chamber A
between the baffels through the flue F over the top of the oven down the side flue M
across the bottom of the oven & up the back to the flue K. It also passes down the
flue G under the ashpan F. Fig. 2 to the flue G under the bottom of the oven & up at
the back flue K.
By this arrangement all cold air is shut out from the flues & perfect combustion
is obtained & all the heat is brought to the top of the range before passing up
the chimney so that kettles and saucepans can be boiled much quicker and with
less fuel.
Having now particulary described and ascertained my said Invention and in what
manner it is to be performed I declare that what my claims are
1. The tubes passing through the Horizontal plate A.
2. The flue passing under the fire & up the back marked E.
3. The flue formed on the top of the oven marked H.
4. The dampers for closing the flue, H, K, marked L.
5. The cast Iron grating for consuming the smoke & preventing the boiler flue C
from being stopped with cinders &c.
