PROVISIONAL SPECIFICATION.
Improvements in Cooking Ranges.
I, JOHN EYRE RUSSELL of Peel Foundry Derby in the County of Derby,
Stove Grate and Kitchen Range Manufacturer do hereby declare the nature of
this invention to be as follows:-
My invention consists in forming a collapseable oven on the hot plate of a
cooking range by means of loose folding iron plates, which when opened out
form a complete oven heated by the fire passing under the hot plate, and which
hot plate also acts as the bottom of the oven, these folding doors or plates are
closed when the oven is not required and leaves the hot plate free and open for
other purposes, the oven now described may be fitted up as a gas oven.

COMPLETE SPECIFICATION.
Improvements in Cooking Ranges.
I, JOHN EYRE RUSSELL of Peel Foundry, Derby, in the County of Derby,
Stove Grate and Kitchen Range 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 :-
My invention consists in forming a collapsible oven on the hot plate of a
cooking range by means of loose folding iron plates which when opened out form a
complete oven heated by the fire passing under the hot plate and which hot plate
also acts as the bottom of the oven. These folding doors or plates are closed
when the oven is not required leaving the hot plate free and open for other
purposes.
The accompanying drawings illustrate my invention and the manner of carrying
it out.
Figure 1 is an elevation of a cooking range fitted with my collapsible oven.
A is the oven door, B B the folding plates which form the side of oven next the
fire. C is a fixed side or support for the folding doors to work on; it is attached
to the back coving D. E is the oven top. F is a plate which covers up the front
of flue and also holds the two side plates together. G is a loose swinging plate
against which the top of the oven door fits to form a joint. H is the side
coving to which the oven door is hinged, it also forms one side of the oven.
J is the damper
II are two soot doors for cleaning out the flue on top of oven.
and flue for working the top oven. K is the damper and flue for the bottom
oven L.
Figure 2 is an elevation of the same cooking range with the top oven folded up
or collapsed.
A is the oven door pushed back against the side coving H. BB are the
folding doors folded back against the back coving D. C is the fixed plate or
support for the folding doors B B to work against, D is the back coving, E the
oven top, F is the plate which forms the front of top oven flue and also holds the
side plate H and the plate C together, G is the loose swinging plate which forms a
joint for the oven door to rest against. H is the side coving to which the oven door
is hinged. II are the two soot doors for cleaning the top oven flue. J is the
damper for working the top oven. K the damper for working the bottom oven,
L is the bottom oven.

Figure 7 is a loose piece fastened to the side coving H and to which the oven
door is hinged.
Figure 8 is the fast plate F connecting the side plates H and C shewing
the hollow or groove in which the swinging plate G works.
Figure 9 is the swinging flap G against which the oven door rests.
Figure 10 is the fixed plate C against which the folding plates B B rest.
Figure 11 is the inside of the plate C one of the folding plates B is hinged
through the holes N N.
Figure 12 is the oven top E showing the flue space O through which the heat
and flame passes to the damper J in Figures 1 and 2.
Figure 13 is the front folding plate B.
Figure 14 is the back folding plate B and shews the round studs P P which
work in the holes N N in Figure 11.
Figure 15 shews the two plates B B joined together.
Figure 16 is the back coving D.
Figure 17 is a section of the top oven showing by the arrows the course of the
heat round the oven.
Having now described the various parts shewn on drawings, the manner of
working the oven is as follows:-To close the oven up, the folding plates B B are
pushed back against the back plate D the swinging flap G is lifted up and the
oven door A pushed back against the side coving H. To make the oven up again,
the door A is first brought forward and then the folding plates B B are drawn out
and fastened by means of a catch or by any suitable means to the side plate C
thus a complete oven is formed. Although I have explained the plan which I
think the best for forming this collapsible oven yet the same thing may be
accomplished by various other means for instance the two plates B B may be in
one or more parts and instead of being hinged to the plate C they may be hinged
to the back plate D or may be hung from the top instead of the side or may be
made to slide either upwards or backwards or they may be a fixture or
they may be quite loose and taken away when the oven is not required. I also
prefer to hinge the oven door to the front edge of the side plate H which
is the outside plate of the range but it may be hinged on the reverse side to the
plates B B and either folded up with them or the plates B B may be fix and the
door close inwards on that side the same as is done on the other side as shewn in
drawing or it may be made to slide sideways or upwards. I also prefer to
construct the oven with a flue around it as shewn in Figure 17 but this flue can be
dispensed with and the oven heated only from the hot plate M. The other parts
shewn on drawing may be altered in detail to answer the same purpose.
This oven
may also be fitted up with gas and used as a gas oven.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what. I
claim is :-
1. An oven substantially as described formed upon the hot plate of a cooking
range by means of loose moveable plates as herein set forth.
2. An oven formed upon the hot plate of a cooking rauge and having its door
closing inwards to the side when the oven is out of use, so that the hot plate of the
range may be clear for other cooking purposes.
