PROVISIONAL SPECIFICATION.
An Improved Cooking Range and Boiler.
1, FREDERICK GEORGE BARTLETT, of Elton Road, Bishopston, in the County of
Gloucester, Plumber, do hereby declare the nature of this invention to be as
follows:-
This invention relates to cooking ranges and boilers, and consists, firstly, in an
improved oven or range heated internally by hot water circulating on the high
pressure principle through pipes arranged therein. The water is heated from a burner
outside the oven.
Before being led into the range the circulating pipe is coiled in a series of coils
arranged ono above the other and together constituting a cap or bonnet. The burner
is surrounded by this cap and the flame plays freely thereon. No gas or oil fumes.
enter the range in which are the usual shelves for the dishes containing the food to be
cooked.
The range is packed or jacketted with any suitable non-conducting material.
The boiler in which this invention, secondly, consists, is conveniently hung or fixed
at that side of the range at which the burner is placed, and the waste heat from the
burner is utilized to heat the water in the boiler. For this purpose the boiler is
provided with a flue extending from top to bottom. Coiled in the flue is a water-
circulating pipe communicating with the boiler. Ovor the top of the flue may be
placed a kettle, saucepan or the liko.

COMPLETE SPECIFICATION.
An Improved Cooking Range and Boiler.
I, FREDERICK GEORGE BARTLETT, of Elton Road, Bishopston, in the County of
Gloucester, Plumber, 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 consists, firstly, in an improved cooking oven or range heated by
means of hot water circulating in pipes arranged within and at the top of the oven.
Outside the oven there is a coil of pipes constituting part of the system of pipes in
which the water circulates.
The external coil is arranged either in the form of an inverted conical cap or is
coiled into any suitable shape. It is exposed to the heat of gas supplied through a
burner placed below or within it. The oven, which is fitted with shelves for dishes, is
packed at the back, sides and bottom with wool or other suitable material.
This invention consists, secondly, in a boiler for use in conjunction with the stove
above described. The boiler which has a central vertical flue or passage is a separate
vessel and is suspended to the stove at that side thereof at which is the external coil.
In the central flue of the boiler is a circulating pipe communicating at one end with
the upper part of the boiler and at the other with the lower part.
Referring to the accompanying sheet of drawings,
Fig. 1 represents a part elevation and part section of a hot water stove constructed
and arranged in accordance with this invention. The door and top cover are
removed.
Fig. 2 is a plan, the top cover being removed.
The stove consists of a metallic chest a packed at bottom, back and sides with

wool or other material suitable for assisting to confine heat. The stove is fitted
with shelves b. Outside the stove is a coiled pipe e exposed to the heat of burning
gas or oil supplied through a suitable burner placed below or surrounded by the coil,
and varying in form according to the fuel employed for heating, whether coal gas
or oil, or oil
gas.
The pipe c is carried up from the burner coil and is extended into the stove and is
arranged therein in a series of approximately rectangular coils. Thence the pipe
is led down and after being coiled in a similar series at the bottom of the stove is
reunited to the burner coil at the bottom thereof.
The stove is surmounted by an enlarged pipe ƒ provided to afford space for
expansion of steam.
Water is poured into the system of pipes through the pipe the cape of which is
removed for the purpose and replaced after charging.
The water heated by the gas Hame brought to bear on the external coil circulates in
the pipes and so raises the temperature within the, stove to the requisite degree for
cooking.
Instead of being arranged in the form of a cone the pipe c may be coiled at the
burner in other ways. For instance, the coils, instead of rising one above the other,
may lie in the same horizontal plane. Or two or more series of horizontal coils may
be adopted, one series being at a suitable distance vertically from the other.
The boiler g, in which this invention further consists, is a metallic vessel having a
central opening or flue into which the external coil extends when the boiler is
suspended to the stove.
The boiler is charged with water through an orifice closed, after charging, by the
"plug i
A circulating pipe & extends across the central flue of the boiler and communicates
therewith at both ends, one towards the top and the other towards the bottom.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
-
1. In an oven or stove for cooking, the employment, for heating the same, of hot
water circulating in pipes coiled or otherwise disposed or arranged within the oven or
stove, the water being heated by a gas or other flame brought to bear on a coiled pipe
external to the oven and forming part of the system of pipes in which the water
circulates, substantially as hereinbefore described.
2. The use, in conjunction with an oven heated by water circulating in pipes
arranged within the same, of a boiler such as g, with central flue and pipe k,
suspended to one side of the oven externally thereto and heated by the same agency as
..the water for circulation in the oven pipes, substantially as herein before described..
