AN IMPROVED PORTABLE OVEN
Year: 1884

page_text: I WILLIAM HILL of 165 Walmer Road, Notting Hill in the county of Middlesex
Manufacturer do hereby declare the nature of my said Invention for AN IMPROVED
PORTABLE OVEN to be as follows:-
The object of my invention is to provide an oven that will be very effective in
baking or otherwise treating articles of food and other articles and I so form this
oven that it shall be readily portable and can be used with and applied to any
ordinary fire grate and can quickly be removed therefrom when the process required
has been accomplished.
To carry out this object I form a chamber of any suitable size and shape and the
casing of this chamber has its top and bottom and two sides made of any suitable
metal or other material that is a good nonconductor of heat preferably I use tin.
The front of the chamber in which is preferably formed a door is also made of the
same metal or material. The back of the chamber which when the apparatus is
placed in position for use in front of the grate faces and is opposite to the fire that
is in the said grate is made of sheet iron or other metal that is a good conductor of
heat and an upper bottom is also formed of the same metal and thus a space is
created and left between this upper bottom and the bottom of the casing which
space is open to the fire towards the back of the casing but is closed round. the
other three sides and the inner chamber of which the top front and two sides are
made of tin or other non-conducting material while the back and bottom are made
of sheet iron or other conducting metal constitutes the oven within which may be
any suitable number of trays or shelves. Suitable handles are fitted to the
casing and when it is placed or hung from the bars in front of any fire grate
the heat from the ordinary fire will play upon the metal back of the oven and
enter the space between the metal bottom of the oven and the bottom of the casing
whereby a great heat will be developed in the oven which heat will not radiate
therefrom owing to the nonconducting properties of the casing and the articles
placed in the oven will be quickly and duly treated as is desired. Any suitable
regulator may be fitted in the door or other part of the casing to allow the heat of
the oven to be properly regulated.

Manufacturer do hereby declare the nature of my said invention for AN IMPROVED
PORTABLE OVEN and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The object of my invention is to produce and provide an oven that shall be very
effective in baking or otherwise treating articles of food and other articles as may
be required and I so form this oven that it shall be readily portable and can be
used with and applied to any ordinary fire grate and can quickly and easily be
removed therefrom when the process required has been accomplished.
In order clearly to explain my invention and in what manner the same is to he
performed I refer to the accompanying drawing in which I have shewn a very
convenient though simple form of this my portable oven.
Figure 1 is a front elevation of the oven in position for use.

In order to carry out my aforesaid object and to construct the oven I form in
any convenient manner a chamber of any suitable size and shape and the casing of
this chamber has its top A and bottom B and two sides CC made of any suitable
metal or other material that is a good nonconductor of heat. Tin is extremely.
suitable for this purpose and in most cases I preferably use this metal therefor.
The front D of the chamber in which is preferably formed a door E is also made of
the same metal or material. The back F of the chamber which when the oven is
placed in position for use in front of the grate as is hereinafter described and as is
shewn in the drawing faces and is opposite to the fire that is in the said grate
is made of sheet iron or other metal that a good conductor of heat and an upper
bottom G is also formed of the same metal and thus a space is created and left
between the said upper bottom G and the bottom B of the casing which space is
open to the fire towards the back of the casing as shewn at H but is closed round
the other three sides and the inner chamber of which the top A front D with the
door E and two sides C are made of tin or other nonconducting material while the
back F and bottom G are made of sheet iron or other conducting metal constitutes
the oven within which may be any suitable number of trays or shelves K.
Suitable handles L are fitted to the casing and when the same is hung by the
hooks M or otherwise on and from the bars N in the front of any fire grate or is
otherwise placed and held and retained near and in front of the said grate the heat
from the ordinary fire that is in the said grate will play upon the metal back F of
the oven and will enter the space between the metal bottom G of the said oven and
the bottom B of the said casing whereby a great heat will be developed in the said
oveň which heat will not to any great or injurious extent radiate therefrom by
reason of the nonconducting properties of the casing and the articles placed in the
said oven will be quickly and duly baked or otherwise treated as is desired and
when the process required has been accomplished the apparatus can quickly and
easily be removed. Any suitable regulator P may be fitted to the door E or other
part of the casing to allow the heat of the oven to be properly regulated.

page_text: I have shewn in the drawing as is herein before mentioned a very suitable and
convenient form of this my portable oven but I would have it clearly understood
that I do in no wise limit myself to the said form or to the methods and details
of construction of the whole apparatus as so shewn for I may make this apparatus
of such a shape and form and such methods and details of construction of the
said apparatus and of the several parts thereof may be observed and followed as
may be suitable or necessary or convenient or desirable in each particular case.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim, is
1. The portable oven made and constructed substantially as herein before
described and set forth.
.
2. In a portable oven the combination of the nonconducting top front sides and
lower bottom and the conducting back and upper bottom substantially as and for
the purpose hereinbefore described and declared.
