Improvements in Oil Cooking Apparatus.
I, DANIEL COLEMAN DEFRIES of 3 Fairfax Road South Hampstead London
Lamp Manufacturer 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 an oil cooking apparatus the application of a boiler round or partly round an
oven such boiler having a bottom surface exposed to the heat of a flame which
flame is placed in such a position as to allow of the heat therefrom being drawn
across the bottom surface of the boiler on its way into the oven. One side & the
top of the oven constitute the one side & bottom of part of the boiler & constitute
further heating surfaces of the boiler. From this boiler (& while meat or other
food is being cooked in the oven) boiling water can be drawn, & the steam generated
in the said boiler can be utilised for steam cooking by allowing it to pass through
a hole of suitable size (made on top of the boiler) into suitable steam cookers
placed thereon.
Fig. 1 is a general view of the apparatus. A. A. is the front of the boiler;
B the side of the oven constituting likewise a side of the boiler; C, C are the
steam cookers placed in position on top of the boiler & fitting into the hole thereon
provided. D is the stove from which the heat is produced.
Fig. 2 is a section cut vertically through the apparatus.
AA is the boiler, B is the oven; CC the steam cookers D the stove from
which the heat is produced E E are the passages through which the heat generated
from the stove is conducted to the bottom of the boiler & into the oven F is an
aperture left in the top of the heat conductors that may be closed by a cooking
utensil which receives sufficient heat on its bottom surface to allow of food being
cooked in it, or it may be closed by a metal plate. The arrows G show the course
taken by the steam generated in the boiler into the steam cookers C. C, through
the aperture K provided on top of the boiler. H is the bottom surface of the
boiler; J the side of the boiler & the oven.
The heat generated by the stove D rises up, & is conducted through the top onc
of the two or more passages E E provided for the purpose of conducting the heat
into the oven & over the bottom surface H of the boiler.

page_text: Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is :-
An oil cooking apparatus provided with a boiler attached to an oven heated in
the manner shewn the whole substantially as & for the purpose described.
Dated this Thirtieth day of January 1893.
