LETTERS PATENT to David Pitcairn Wright, of Birmingham, in the County of
Warwick, Manufacturer, for the Invention of IMPROVEMENTS IN HYDRO-
CARBON COOKING STOVES."
Sealed the 23rd August 1878, and dated the 9th March 1878.
PROVISIONAL SPECIFICATION left by the, said David Pitcairn Wright at the
Office of the Commissioners of Patents on the 9th March 1878.
DAVID PITCAIRN WRIGHT, of Birmingham, in the County of Warwick, Manu-
facturer. "IMPROVEMENTS IN HYDRO-CARBON COOKING STOVES."
This Invention is for an improved arrangement by which with one or more flames
both boiling and baking can be carried on at the same time, the latter by means of
the hot air from the flue or chimney entering at the top or nearly at the top of the
oven, and finding its exit,up a chimney or cavity, the inlet to which is nearly at
the bottom of the oven.
This Invention consists of cast or wrought iron sides, to which are attached an
iron or tin compartment, with a division plate, which forms one side of the chimney
or flue, or with a distinct and separate chimney or flue at one end of the compart-
ment without a division plate; this compartment, either divided with a division
plate or with the flow at one end without the division plate, forms the oven for
baking or other similar uses
The chimney or flue is open some distance below the top plate of the stove or
oven, so that when the opening or openings in the top plate are covered the entire
amount of hot air passing up the chimney enters the oven at or near the top, and as
it cools descends and finds its egress through either a distinct chimney or up one
side or back of the oven partitioned off to form a chimney for the escape of the
same; by this means boiling is easily carried on in any vessel placed on the top of

page_text: the stove, and the hot air which enters and passes through the oven at the same time
bakes in the most perfect manner.
My Invention also consists in the using non-conducting material, such as wood
or other substance, to break the connection of the iron frame which contains the oil
vessel and burner or burners, and the oven.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said David Pitcairn Wright in the Great Seal Patent Office on the 9th
September 1878.

Having thus described the nature and object of my said Invention, I declare
that what I claim and desire to be secured to me by the herein-before in part
recited Letters Patent, is,—
Firstly. The improved arrangement of apparatus by which with one or more
flames both boiling and baking can be carried on at the same time in the manner
substantially as herein-before described and shewn on Drawing.
Secondly. The means of breaking connection of the iron frame which contains the
oil vessel and the burner or burners and the oven by the use of non-conducting
material, such as wood or other suitable substance, as herein-before described.
In witness whereof, I, the said David Pitcairn Wright, have hereunto set my
hand and seal, this Seventh day of September, in the year of our Lord
One thousand eight hundred and seventy-eight.
