1, THOMAS HUNGATE PRESTON DENNIS of 20 High Street, Chelmsford Essex,
Engineer and Ironmonger do hereby declare the nature of my said invention to be as
follows:-
My invention consists of a Cooking Apparatus or Kitchen Range with the usual
oven or ovens--hot plate and boiler or boilers the chief feature of which is that its
fire basket or fuel container is placed wholly or partially within the oven or ovens the
air of which it heats by direct contact and radiation and not by flues carried around
the oven or ovens in the customary manner.
The Apparatus may be made rectangular, circular, semicircular, or of any desired
form The fire basket or fuel container may be made of fire bricks or iron or other
known fire resisting material and may be placed in any convenient position-wholly
or partially within the oven or ovens it is desired to heat it may be made of any
desired form but I prefer a circular shape made of segments or parts built up and held
together by bands of hoop iron-wire-or supports of any convenient form as described
in my patent No. 3310 or it may be self supporting and of one or more parts.
In the case of arranging the fire basket or fuel container partially within the oven
or ovens I fit grating or fire bars of convenient size to a portion of the fire basket or
fuel container, such grating or fire bars to be placed up to an aperture of correspond-
ing size and shape in the front of the Range or Apparatus for the convenience of
roasting as before an open fire and a door or doors are fitted to enclose the fire bars-
the other portion of the fire basket or fuel container being within the oven or ovens
and in direct contact with the air or space of same.
In the case of placing the fire basket or fuel container entirely within the oven or
ovens I make it by either manner before alluded to, I also sometimes fit the grating
or firebars to a portion of it (with the door or doors fitted thereto) for the purpose of
roasting before the fire contained therein and in such case the joint to be cooked is
hung or placed in front thereof entirely within the oven or ovens-this portion of the
apparatus may be partitioned off from the oven or ovens to form an independent
roaster I fit a plate of wrought or cast iron to form the top of oven or ovens and

page_text: above this, with a convenient space between I fit the hot plate or top surface plate or
plates of the Range-The fire basket or fuel container is usually placed on or near the
bottom of the oven or ovens with its top or upper shell or surface projecting a conve-
nient distance through the plate which forms the top of the oven or ovens so that the
smoke and products of combustion are admitted into the space between the top of the
oven or ovens and the hot plate or top surface of Range before alluded to-A Smoke
nozzle is attached to the space into which the smoke or products of combustion are
emitted to carry them into the chimney or smoke flue-Suitable damper or dampers
are arranged either in connection with the smoke nozzle or otherwise by which the
products of combustion may be carried either directly into the smoke flue or they may
be diverted by means of flue plates to traverse the entire surface of the hot plate before
entering the smoke flue-Any desired form of water boiler or boilers may be added
and may be placed in any convenient position around or about the fire basket or fuel
container or the boiler or boilers may be placed above the fire basket or fuel container
and the heated air which passes off from the fire may be directed to any desired
portion of the boiler surface to heat the water before passing into the smoke flue.

I THOMAS HUNGATE PRESTON DENNIS Engineer and Ironmonger Chelmsford Essex,
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:-
My invention consists of a Kitchen Range or Cooking Apparatus with oven or
ovens Hot Plate and Boiler or Boilers. Its chief feature is that its fire basket or fuel
container is placed wholly or partially within the oven or ovens the air of which it
heats by radiation and direct contact therewith and not by connection from heated
flues carried around the oven or ovens in the customary manner.
The form of the apparatus may be rectangular semi circular circular or of any
convenient shape.
The fire basket or fuel container may be made of fire brick or iron or other known
fire resisting material. It may be placed in any convenient position either wholly or
partially within the oven or ovens it is required to heat and may be of any desired
form but I prefer a circular shape made segments or parts built up and held
together by bands of hoop iron wire or any suitable material as more particularly
described in my patent heating apparatus No. 3310 or it may be self supporting and
in one or more parts.
In arranging the fire basket or fuel container wholly within the oven or ovens I
simply place it on or near the bottom of oven or ovens in any convenient position with
the top or upper portion of its shell or surface extending a convenient distance
through the top part of oven or ovens where the products of combustion are discharged
into a chamber directly under the hot plate of apparatus as hereinafter described.
I sometimes place the fire basket or fuel container partially or wholly below the
bottom line of oven or ovens and when arranged thus it is more convenient to con-
struct it horizontally with one or more uptakes therefrom leading to the space between
the top of oven or ovens and the hot plate.
These uptakes provide a ready means of charging the firebox with fuel in addition
to their proper function of conveying the products of combustion to the chamber
directly under the hot plate.
When it is found to be more convenient for some purposes to arrange the fire
basket or fuel container partially within the oven or ovens one of its sides or a portion
of its outer surface is placed up to or near the front of Range or Apparatus where an
aperture is left to receive it the remaining portion being within the oven or ovens.
I usually construct sliding or hinged doors to cover said aperture and with this
arrangement (the doors being opened) roasting or other cooking can be proceeded
with at the same time the ovens are being heated.
A small door is fitted in a convenient position near the bottom of fire box or fuel
container to rake out dust and remove ashes.
Fire bars may be fitted to any portion of the fire box.
In the case of large Apparatus one or more partitions may be fitted within to form
