CHARLES HORACE WALL REMMETT 3 Ebenezer Place Wyndham Road
Camberwell London Engineer do hereby declare the nature of this invention to be
as follows:-
:-
This oven is composed of a double jacket. The top plate being so made to
cause the heat from grate fire, gas ring, gas or any other kind of stove to pass
under bottom and up sides through flues holes and out over top into ordinary
current.
It is also supplied with a loose bottom which is so arranged in size and other
particulars that it can be removed and placed in back of oven and thus converting it
into an over fire oven.

A Portable Oven for Front or Over Fire.
CHARLES HORACE WALL REMMETT 37 Harris Street Southampton Street
Camberwell S.E. Engineer late of 3 Ebenezer Place Wyndham Road Camber-
well S.E. 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 relates to a portable oven for domestic and other purposes, and so
arranged as to be capable of attachment to the front, side or top of any ordinary
fire grate, kitchener, or gas or petroleum stove, the object of my said invention
being to utilize the waste heat radiated from such grate or stove, as a medium for
heating my said improved portable oven, without in any way interfering with, or
retarding the uses of the grate or stove to which it may be applied.
In order that my invention and the manner of using same may be the better
understood I have appended hereunto a sheet of drawings, in which,
Fig. 1 is a front elevation of the entire apparatus with the hinged door removed
for the purpose of shewing the interior of the oven proper.
Fig. 2 is a back elevation of same with the portable back plate partly raised
and shewn in dotted outline.
Fig. 3 is an under plan view of same, with the said portable plate partly in
position thereon, and shewn in dotted outline.
Fig. 4 is a horizontal section taken upon the line A B Fig. 2.
Fig. 5 is a like section of same taken upon the C D.
Fig. 6 is a vertical section of Fig. 2 taken upon the line E F.
I
carry my invention into effect by constructing from any suitable metal,
but preferably rolled sheet iron, a rectangular outer casing A, the front of
which A is partly open as at Fig. 1, and provided with lugs a b upon which
is hinged a door Bas at Fig. 6. The back of A may be partly open, or
entirely so as at Fig. 2, and provided with vertical guides a d, into which may
slide a plate C, for enclosing said back when desired. The bottom of A,
narked A", may be left wholly open, or partly so, as at Fig. 3, and provided
with horizontal guides ef, for the reception of the plate C, for enclosing ▲" when
desired, thus may be employed for closing up the bottom or back of A, as the
oven may need to be used upon the top, or at the front of the grate or stove.

page_text: Within the chamber A I fix a like shaped but smaller chamber D, the only open
portion of which is that side thereof which is rivetted or otherwise attached to the
inner surface of the front of A, the door B of which, when closed, would also
enclose the only entrance into D. The roof D' of D may be made integrally with the
sides and back of same or attached thereto as may be desired, and would be of such
a width, as to occupy the entire width of A and be rivetted or otherwise connected
to the sides thereof, the front of D' being also in like manner connected to the inner
surface of A, and provided at its corners with openings 9 h. The chamber D may
be provided with any number of plinths k, for carrying a portable shelf or
shelves m. The manner of using said oven is as follows.
If the oven is to be used in front of the fire grate, or gas or oil stove, the same may
be stood upon the usual sliding trivet provided in the front of such grates or stoves
with it back towards the fire in which case the plate C would be slid into the
grooves ef, thus enclosing the bottom A", and leaving open the back of A. The
heat given off from the front of said grate or stove would pass under the bottom
of D, and upwards between the sides of same and the outer casing A, and through
the apertures g h in D¹, from which it would be led by connection over the top
of D in a backward direction into the updraught of the grate or stove and be
carried off thereby. Thus the heat that would be otherwise wasted from the grate
or stove, is caused to pass around D as stated, and be imparted thereto, and serve
for cooking any viands that may be placed therein, and for regulating the
temperature in D, a suitable ventilator or ventilators may be provided in B in the
usual way, or the apparatus can be moved farther from the grate or stove, or
placed upon the hob or side of the top of same with its back still to the fire. Or
if desired the said oven can be placed directly over the fire in the grate, or over
the circular opening in the top plate of the kitchener, or over the top of a gas fire,
or the ring jet of a gas stove, in which cases the plate C would be slid into the
grooves cd, thus enclosing the back of A, and opening the bottom A" of same.
In this method the heat would pass up between C and the back of D. in addition to
that of the bottom and sides thereof as previously explained, before passing out
through the apertures 9 h.
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,
In an improved oven, to be used in front, or over the top of domestic fire grates, or
gas or oil stoves or gas rings, for utilizing the waste heat from same for cooking and
other purposes, the construction and use of a metallic case A, with openings at the
back, bottom and front of same, the latter enclosed by a door B, hinged to A at a l», and
provided with an inner chamber D, with enlarged top plate D' with aperture g. h,
and fixed to and within A in such a manner that an air passage exists between D
and A through g and h. The slide guides c d for the reception of a plate C for
enclosing the back of A, and guides ef for the reception of C when used for
enclosing the bottom A" of A, the whole connected, combined and operating
substantially as and for the purpose herein described and shewn by the accom-
panying drawings.
