I, WILLIAM PHILLIPS THOMPSON, Fel. Inst. P.A. of the Agency for Foreign
Patent Solicitors, 6 Lord Street, Liverpool, in the County of Lancaster, and 323 High
Holborn, in the County of Middlesex Civil Engineer, do hereby declare the nature of
this invention to be as follows:-
This invention has for its object economy of fuel of which it may use almost any
kind, and, at the same time to perform cooking operations better than those now in
use and afford increased space for such purposes.
It is proposed to effect this by enclosing the oven on three sides, the top, rear and
bottom, by a continuous flue along which the products of combustion pass from the
firebox placed in the front to the outlet or take off pipe in the rear.
In the part of this flue underneath the oven is placed a horizontal diaphragm over
and under which the gases will pass and in some cases substitute for the diaphragm a
second oven.
This continuous flue will be the width of the oven, that is of the stove, and has
dampers arranged in it to divert and govern the course of the gases.
In the bottom of the oven and preferably near the front are formed a series of
openings through which the steam of cooking is drawn out of the oven; these are
lined with wire, gauze, etcetera, and have a slide operated from the outside, for
closing them.

St. John's, in the Colony of Newfoundland, Stove Manufacturer.
I, WILLIAM PHILLIPS THOMPSON Fel. Inst. P.A. of the Agency for Foreign
Patent Solicitors 6, Lord Street, Liverpool in the County of Lancaster, and 323 High
Holborn in the County of Middlesex, Civil Engineer, 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 the production of a stove, which shall perform the
cooking better, and with less consumption of fuel than those now in use, burn either
wood, or hard or soft coal, and give an increased space for general cooking
purposes.
It may be described as consisting broadly in forming above in the rear of, and
below the oven, a continuous flue or chamber, the whole width of the stove, along
which the products of combustion can be made to pass to the point of exit, their
course being governed by suitable dampers, and furthermore in providing means by
which the oven can be ventilated, and the steam from articles being cooked be drawn
off into the flue.
For full comprehension of the invention, reference must be had to the annexed
drawings, forming part of this Specification in which,
Figures 1 and 2 show longitudinal sectional perspective views of a stove embodying
the invention, and, Figures 3, 4, and 5, longitudinal sections through stoves showing
modifications of same.
Similar letters of reference indicate like parts.
F is the fire box of any usual construction, O the oven the full width of the stove,
and S the soot door. A is the continuous flue or combustion chamber, also the full
width of the stove, and of suitable depth, passed from the fire chamber proper, over
the oven as at a, in rear of it as at a¹, and below it as at a³, this part communicating
with the stove pipe B. (is a plate or diaphragm placed horizontally in a², the full
width of the chamber, and arranged so as to allow the products of combustion to pass
round its front end. D is the damper for controlling the course of the current of the
products of combustion, which when in the position shown in Figure 1 will direct
them under the oven, and round the diaphragm, and when set as in Figure 2 will
send them directly from a' into the stove pipe.
In Figure 3 another oven or hot closet Ę is substituted for the plate C, the
damper D turning the products of combustion round this or directly down a¹ to the
stove pipe B.
Figure 4 shows a modification in which the lower part of the stove pipe B is
within the stove, and separated from a¹ by a diaphragm G, in which are formed two

page_text: sliding dampers D, D', which may be connected together so that when D¹ is raised
so as to cut off B from a, the damper D is open, so as to allow of the passage of
smoke etcetera, from the underside of the plate C into the pipe B. The opening
of D₁ will close this passage, and open communication directly between a and the
pipe B.
In Figure 5 the oven is surrounded on four sides by the combustion chamber, the
additional part as being between the fire box F and oven O, and the damper D being
placed at the entrance of a.
It is proposed to form in the bottom of the oven O, and as near as possible to the
front plate 01, a series of openings H, through which the steam and gases arising
from the article being cooked will be drawn into the flue a². These openings will be
preferably lined on the under side with gauze, and be provided with a slide H operated
from the outside, for wholly or partially closing them.
The corners of the oven are preferably rounded, as shown in the drawing, so as to
facilitate the passage of the products of combustion.
The combustion chamber A can be cleaned very easily, the parts a and a¹ through
the openings in the top plate, and a through the soot door.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :—
1. In a cooking stove, the combination with an oven the full width of the stove, of
a continuous combustion chamber of like width, passing round three sides of oven, from
fire box to eduction pipe, and damper for regulating the current, all as and for the
purposes herein set forth.
2. The combination with the part a² of the continuous chamber A, of the diaphragm C
and damper D, all as herein described, and for the purposes set forth.
3. The combination with the oven O, and continuous chamber A of the openings H
and slide H¹, as and for the purposes described.
