PROVISIONAL SPECIFICATION.
Improvements in Portable Ovens.
I ISAAC GILL of Ainstable in the County of Cumberland Monumental Mason do
hereby declare the nature of this invention to be as follows:-
In the ordinary form of portable ovens for domestic use, commonly known as
"Dutch Ovens," I effect an improvement enabling them to be heated rapidly and
with great economy by constructing them in the following manner :-The oven is
made of sheet iron adapted to stand or hang over the fire in the same manner as a
kettle or pan. The oven is divided into compartments one on each side of the oven,
the centre compartment being the one in which the viands or comestibles are placed
for roasting or baking. The lower portion of the side compartments are open allowing
the heat to pass upward and over the top of the cooking compartment before it escapes
and ascends the chimney.
A handle for attaching the oven to the crook, and other details such as are found
in the common forms of portable ovens, are attached to my improved ovens when
required.

Improvements in Portable Ovens.
I, ISAAC GILL of Ainstable in the County of Cumberland Monumental Mason 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 :-
In the ordinary form of portable ovens for domestic use commonly known as Dutch
ovens, I effect an improvement enabling them to be heated rapidly and with great
economy. I construct my improved oven in the following manner :-
•
The oven is made of sheet iron adapted to stand or hang over the fire in the same
manner as a kettle or pan is commonly placed. My improved oven is divided into
compartments one on each side of the oven. The centre compartment being the one
in which the viands or comestibles are placed for roasting or baking. The lower
portions of the side are open allowing the heat to pass upwards and over the top of the
cooking compartment before it escapes and ascends the chimney. A handle for
attaching the oven to the crook and other details, such as are found in the common
forms of portable ovens, are attached to my improved oven when required.
In order that my invention may be better understood I append drawings in
which
