HEARTHS OR COOKING APPARATUS."
PROVISIONAL SPECIFICATION left by the said Alphonse René le Mire de
Normandy at the Office of the Commissioners of Patents, with his
Petition, on the 15th April 1864.
I, ALPHONSE RENÉ LE MIRE DE NORMANDY, of Odin Lodge, 5, King's Road,
Clapham Park, Surrey, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN SHIPS' HEARTHS OR COOKING APPARATUS," to be as
follows:-
My improvements .consist in a method of constructing cooking hearths,
which improvements are illustrated in the annexed Drawing. The Drawing
represents a sectional elevation of one of my hearths provided with a side;flue
for receiving the waste heat from a steam, boiler, with which we will suppose
it to be connected.
A, side flue; B and C, ovens ; D and E, boilers or pots; F, flues of hearth,
the products of combustion move in the direction shown by the arrows; G
and H, dampers for regulating the heat; I, chimney; J, fire-place. This
hearth is constructed principally of cast iron, and the plates are held in place
by suitable flanges; K, K, K, and wedge pieces L, L, L, so arranged that
only six long bolts M or stays are required to hold the plates together, as will

page_text: be seen in the annexed Drawing. The oven plates may if desired be made of
wrought iron, and the long bolts M, instead of pulling against a loop N cast
in the bottom plate, as shewn in the Drawing, may be terminated by an ordinary
SPECIFICATION filed in pursuance of the conditions of the Letters Patent
and of an Order of the Lord Chancellor, by the said Alphonse Normandy
in the Great Seal Patent Office on the 7th November 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALPHONSE
NORMANDY, of Montague Place, Clapham Road, in the County of Surrey, Son
and Administrator of Alphonse René le Mire de Normandy, of Odin Lodge,
5, Kings Road, Clapham Park, Surrey, deceased, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of April, One thousand eight
hundred and sixty-four, in the twenty-seventh year of Her reign, after reciting
that the said Alphonse René le Mire de Normandy did by his Petition
humbly represent to Her said Majesty that he was in possession of an
Invention for "IMPROVEMENTS IN SHIPS' HEARTHS OR COOKING APPARATUS," which
the Petitioner believed would be of great public utility, that he was the first
and true Inventor thereof, and that the same was not in use by any other
person or persons to the best of his knowledge and belief, the Petitioner
therefore most humbly prayed that Her said Majesty would be graciously
pleased to grant unto him, his executors, administrators, and assigns, Her
Royal Letters Patent for the sole use, benefit, and advantage of his said
Invention within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, for the term of fourteen years, pursuant
to the Statute in that case made and provided, and reciting that the said
Alphonse René le Mire de Normandy departed this life on the Tenth day of
May, One thousand eight hundred and sixty-four, and that letters of adminis-
tration, with the will annexed, were granted to me, the said Alphonse Normandy,
on the Twenty-fourth day of June last, and that Her said Majesty being
willing to give encouragement to all arts and inventions which might be for
the public good, was graciously pleased to grant to me, the said Alphonse
Normandy, as such Administrator as aforesaid, Her Royal Letters Patent, and
did give and grant unto me, the said Alphonse Normandy, my executors,
administrators, and assigns, Her especial license that I; the said Alphonse
Normandy, my executors, administrators, and assigns, or such others as
I, the said Alphonse Normandy, my executors, administrators, or assigns,

page_text: should at any time agree with, and no others, from time to time and at
all times thereafter during the term of years therein expressed, should and
lawfully might make, use, exercise, and vend the said Invention within the
United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, upon the condition (amongst others) that I, the said Alphonse
Normandy, should by an instrument in writing under my hand and seal
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 on or before the Seventh day of
November, One thousand eight hundred and sixty-four.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Alphonse Normandy, do hereby declare that the nature of the said Invention,
and in what manner the same is to be performed, are particularly described
and ascertained in and by the following statement thereof, that is to say:-
In constructing ships' hearths or cooking apparatus, according to the
Invention, cast-iron plates are by preference used, though wrought-iron plates
may be employed in place thereof; such plates are made with flanges and
inclines or wedge pieces in such manner that all the plates forming the ovens,.
fire-place, and exterior case will support each other in place without any bolts.
being required, but I prefer using a few long bolts or stays (which pass from
top to bottom), and by screw nuts the whole structure is held more firmly
together, and consequently by this arrangement the hearth can be quickly put
up or taken down. The exterior case is of rectangular form, the upper plate
or plates having openings through it or them to receive kettles, boilers, or
cooking vessels. The fire-place is lined with fire-brick, and the bottom below
the ash-pit is closed, leaving a space between the interior of the case and the
bottom of the ash-pit, by which provision is made for the passage of the
products of combustion under the fire-place. The fire-place may have an
oven applied on one or on both sides of it, and is made of cast-iron plates
with flanges, so that when placed in position within the outer case the plates
are kept in place by each other and by the flanges and inclines on the plates
of the outer case. When two ovens are used, the products of combustion pass
from the fire over one oven and down at the side or end, then under the oven, and
next under the fire-place, afterwards under and over the second oven, and thence
away to a chimney; or the products of combustion may be divided and pass
over both
ovens, then down and under each oven into the space below the ash-
pit, and thence to the chimney, the waste heat when desired

oven is employed, then the products of combustion, after passing over and
being in either

applied when' desired to heat a boiler as before described; and both single and
double oven hearths may when desired' be provided with a damper, so as to
allow more or less heat to pass to the chimney without circulating round the
ovens, so as either to regulate the heat or generate more steam when fitted
with a boiler. Sometimes also the products of combustion pass direct from
the space under the ash-pit to a chimney fixed on the back or end plate of the

apparatus constructed and combined according to the Invention; Figure 2 shews:
a vertical transverse section taken through the fire-place, and Figure 3 shows:
another vertical transverse section through one of the ovens of one of the
double oven hearths with a split draught. The sectional plan of both halves
of this hearth, either on the right or left of the centre line B¹, B¹, would be
similar to that part of the sectional plan, Figure 5, which is to the left of the
centre line A, A', through the fire-place. A is the fire-place, a lining of
fire-brick Q is interposed between the interior of the fire-place and the exterior
of the oven, and also on the top of the ovens. on either side; B; B, are ovens,
which are each composed of plates of cast iron cast with flanges so that they
go together without other fastenings than those of the exterior case, on which
there are certain supports or projections for the parts of the ovens as hereafter.
described; C is an outlet for the passage away of the products of combustion,
to which would' be attached a chimney, as in Figure 8, if there be no boiler
over it, as shown at W, which at its back has one or more tubes or flues U, U,
as shown, up through which the products of combustion rise after quitting. the
ovens and beat the contents of the boiler; V, V, are manholes or openings with
suitable covers; D is a damper, which when in the position shown in Figure:2
causes the products of combustión to pass in the directions indicated by the
arrows; Figure 1, but when drawn back more or less of the products. can pass
direct to the space C leading to the chimney; F are flues by which the products
of combustion circulate around the ovens, as indicated by the arrows; H are
wedge pieces or inclined projections, and K are flanges which retain the plates:
of the outer case in position, and there are other like. projections H and
flanges K which receive and support the plates of which the ovens are
composed in position. These projections, together with the flanges! K. formed.

parts securely together and in their proper places; I prefer however using also
long screw bolts G, so as to hold the plates more firmly, and the heads which I
prefer should be recessed in and come flush with the upper surface of the top
plate, whilst the nuts come below the bottom plate. M, M, are the oven doors;
N is the fire-door; O, fender, hooked on to projection P; a soot hole is made

serves as usual as a hot plate, and whether in one or more pieces it has
openings in it to receive boilers or cooking vessels T. When the draught is
not split the plate Y, damper D, and flue at the back of the fire-place F is
dispensed with, and the fire-bars are lengthened so as to reach from front to
back of hearth, the back plate being protected by fire-brick similarly to the
side oven plates. In this case also the opening to the chimney is over either
one of the ovens, direct communication with the chimney being regulated by a
damper situate between the opening and fire-place, as at Z, drawn in blue,
Figure 1; the waste heat may also be used to generate steam, as in the former
case. Figure 4 shows a plan, Figure 5 is a horizontal section; Figure 6
shows a front elevation; Figure 7 is a front elevation in section; Figure 8 is
a transverse section taken through the fire-place, and Figure 9 shows a front
elevation in section, and Figure 10 a sectional plan with flue leading to
chimney at the side of fire-place instead of the back thereof. In these
Figures the same letters are used to indicate the like parts to those previously
described, and the description before given applies to this arrangement, wherein
only one oven is employed, and consequently need not be repeated here. In
this and the other arrangements there are at the angles small pillars X, X, for
carrying guard rails for the boilers.
Having thus described the nature of the Invention, and the manner of
performing the same, I would have it understood that I make no claim to the
mechanical parts separately, but I claim the combined arrangements herein
described.
In witness whereof, I, the said Alphonse Normandy, have hereunto set
my hand and seal, this Seventh day of November, in the year
of our Lord One thousand eight hundred and sixty-four.
A. NORMANDY. (L.S.)
