IMPROVEMENTS IN KITCHENERS
Year: 1862

page_text: LETTERS PATENT to Thomas Attwood, of Lewes, in the County. of Sussex,
Ironmonger, for the Invention of." IMPROVEMENTS IN KITCHENERS."
PROVISIONAL SPECIFICATION left by the said Thomas Attwood at the
Office of the Commissioners of Patents, with his Petition, on the 21st
April 1862.
I, THOMAS ATTWOOD, of Lewes, in the County of Sussex, Ironmonger,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
KITCHENERS," to be as follows:-
The improvements in the kitchener are as follows:-1st, I make the oven
the doors
door in two parts; and so arrange the fittings that when.open
stand at right angles with the front. On the inside I form ledges or rests in a
direct line with the ledges or rests of the oven, so that when the doors are
set open they form a continuous slide, on which the meat or anything that
may be cooking may be drawn out of the oven, so that basting, flouring, or
changing may be carried on with the greatest possible facility. One door
might also be so fitted, if the sliding piece on the opposite side projected
sufficiently far back to support that side of the plate when it is drawn out.
2ndly, a new mode is adopted in the construction of the oven. The
bottom, stops or flue plates are formed of the same piece of metal as the
bottom, which gives a greater amount of conduction for the heat to that
part, consequently a greater amount of bottom heat is obtained.

slides laterally behind the front plate of the boiler. This is a great advantage,
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Attwood in the Great Seal Patent Office on the
21st October 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
ATTWOOD, of Lewes, in the County of Sussex, Ironmonger, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of April, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Thomas Attwood, Her special licence that I, the said Thomas
Attwood, my executors, administrators, and assigns, or such others as I, the
said Thomas Attwood, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
KITCHENERS," upon the condition (amongst others) that I, the said Thomas
Attwood, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that J, the said Thomas Attwood, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, reference being had to the Sheet of Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say): :-
•
My improvements in the kitchener are as follows:-According to my
Invention I make the oven door in two parts, and so arrange the fittings that
when open the doors stand at right angles with the front. On the insides of
the door I form ledges or rests, which with the doors in the open position
above mentioned are in a direct line with the ledges or rests of the oven,

page_text: and in such manner that when the doors are so set open they form a con-
tinuous slide, on which the tray or shelf on which the meat or anything that
may be cooking is placed can be drawn out of the oven, for the purposes
of basting, flouring, changing, or otherwise, which can thus be carried on
with the greatest possible facility. An oven furnished with one door only
might also be so fitted, to enable which I project a sliding piece on the
opposite side of the shelf or plate sufficiently far behind to support that side.
of the plate when it is drawn out.
•
The second part of my Invention relates to a new mode of construction
of the oven, which consists in making, the lower flue stop and, the bottom
plate of the oven of one and the same piece of metal, which affords a greater
amount of conduction of heat to the bottom of the oven, consequently the
desideratum of a greater amount of bottom heat is obtained.
The third part of my Invention relates to making- the firedoor simply to
slide instead of being hung with hinges as usual. For this purpose I construct
and fit the fire door to the kitchener so as to slide laterally behind the front
plate of the boiler. This is a great advantage both when such door is used
as a regulator, and for roasting in front of the fire.
DESCRIPTION OF DRAWINGS.
Fig. 1 represents a front view of a close kitchen range, or kitchener:, a, a,
are the oven doors represented open; it will be seen, they stand out from the
face of the range at right angles thereto, their hinges being so constructed as
to prevent them opening beyond that point, or this may be insured by other
suitable stops; b, b, are ledges of the oven, on which the trays or shelves c
rest as in ordinary; on the same level as these ledges I form ledges or grooves
d, on the inside of the oven doors, which are narrow and take up little room
in the oven when closed, when open these ledges form, continuations of the
ledges b, and therefore give support to the shelves c, when withdrawn from
the oven, which offers great convenience in cooking either for inspection,
turning, basting, or otherwise treating the edible substances under operation,
as they may be at the time wholly withdrawn from the oven without the
inconveniences attendant upon removing them, as in ovens fitted in the
ordinary manner.
I
Fig. 2 represents an oven fitted with one door only, the ledge d being
therefore on one side only for the support of the oven shelf c; to ensure the
proper support of the shelf I carry a projection e back behind the opposite
side of the shelf, which projection is never to be withdrawn from the groove
b of the oven side, so that with this bearing for the shelf on one side, & that of

page_text: the door ledge or groove d on the other, it will be sufficiently supported
although withdrawn from the oven.
is only in one direction,
Fig. 3 represents a lateral vertical section of an oven with the flue stops
constructed according to my Invention. I make the body of the oven of plate
or sheet iron, as at f,f; in its construction I throw out of the same piece
of metal the stop g of the flue, this may either be of a single thickness
In the case of its being
as at Fig. 3, or it may be double as at Fig. 4.
single as at Fig. 3, the conduction of the flue heat
there being a junction of the metal at the stop, and therefore the heat is so
conducted only to the one half of the oven bottom, whereas as shown at
Fig. 4, in which the stop is double, the whole of the oven bottom and stop
is of one piece, and the heat conducted throughout its entire area.
might be also acquired although the stop were of a single thickness, by making
the stop at the side of the oven instead of in the middle, but this is an incon-
venient position for the flue stop, and the heat has to be conducted further by
the metal.
This
The third improvement according to my Invention is represented at Fig. 1,
the fire-door in which, it will be seen, is fitted to slide laterally, and to pass
behind the plate in front of the boiler instead of being hinged as usual, and as
will be readily understood.
Having described the nature of my Invention and the manner of performing
the same, I declare that what I claim as my Invention to be protected by the
herein-before in part recited Letters Patent, is,-
First, fitting and furnishing the oven doors of kitcheners with slide
ledges or supports for the shelves, as and for the purposes herein-before
described.
Secondly, I claim making the flue stops herein-before mentioned in one
and the same piece with the bottoms of the ovens of kitcheners, as and for the
purpose herein-before described.
Thirdly, I claim making and fitting the fire doors of kitcheners to slide
instead of being hinged, as herein-before described.
In witness whereof, I, the said Thomas Attwood, have hereunto set my
hand and seal, this Eighteenth day of October, in the year of our Lord
One thousand eight hundred and sixty-two.
THOMAS ATTWOOD. (L.B.)
