WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Fifteenth day of De-
cember (One thousand eight hundred and forty-nine), in the thirteenth of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Alfred Dalton, my exors, adiñors, and assigns, Her especial licence,
full power, sole privilege and authority, that I, the said Alfred Dalton, my
exors, admors, and assigns, or such others as I, the said Alfred Dalton, my
exors, adññiors, or assigns, should at any time agree with, and no others, from
time to time and all times during the term of years therein expressed,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "IMPROVEMENTS
IN REVERBERATORY AND OTHER FURNACES;" in which said Letters Patent is contained
a proviso that I, the said Alfred Dalton, shall cause a particular description of
the nature of my said Invention, and the manner in which the same is to be
performed, by an instrument in writing under my hand and seal, to be inrolled
in Her Majesty's High Court of Chancery within six calendar months
next and immediately after the date of the said in part recited Letters Patent,
as in and by the same, reference being thereunto had, will more fully and at
large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, 1, the said
Alfred Dalton, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had to
the Drawings hereunto annexed, and to the figures and letters marked
thereon, that is to say :-
My Invention is applicable to furnaces wherein atmospheric air is intro-
duced above the fire bars at the sides of furnaces. Many furnaces have been
made with numerous openings at the sides, in order to admit currents of air
into the fires above the fire bars, and the material usually employed has been
fire brick or stone, and the openings have been obtained, either by setting the
bricks apart, or else by having the sides made of lumps of fire clay, or of stone'
with numerous perforations through the same to admit air to the fuel above
the fire bars; but in those cases it has been found that, in consequence of the
great heat to which some furnaces are liable, parts of materials of which the
roofs and sides of the furnaces are composed melt; and run down the sides,
which, together with the clinkers formed by the fuel, stop up the holes. Now
my Invention has for its object, amongst other improvements, to obviate this
prejudicial effect by causing the sides to stand back or in recesses, so that the
matters melting at the roof and upper parts of the sides of a furnace, in place
of running down the sides and into the holes or openings for the passage of air,
such melted matters drop down without coming to those parts of the sides of
furnaces, so that the sides stand off' from such dropping, and therefore the holes
or air passages therein are not so liable to become.filled up; and this is the
case whether the sides of furnaces are made of fire bricks, fire lumps, or
tiles, or fire stone, or of iron; but such recessing or setting back of the sides of
furnaces is most beneficially applicable when using the fire bricks or fire lumps,
or tiles or stone; I prefer, however, to use iron in forming the sides of furnaces,
and that the iron should be in the form of perforated plates, but the same may
be used as bars or other forms, so that they are suitable for the passage of
several streams of air on any side of a furnace, the sides being set or recessed
back where the streams of air enter, so that any melted matter running down
from the roof or upper parts of the sides of a furnace, the same will drop down into
the furnace without running into the holes or air passages so as to fill them up.
Another part of my Invention is applicable to puddling, re-heating, and
other similar furnaces used for heating and melting iron, and consists of
forming the sides of iron with suitable means for introducing streams of air
into the furnace above the fire bars; this may be best done by having the
sides of iron plates, with perforations; but other forms of iron, such as bars

with spaces between them, to admit of streams of air passing freely to the fuel
above the fire bars, may be used, this part of my Invention consisting of the
use of iron for the sides of fuanaces, when those sides are so formed as to
admit streams of air to the fuel above the fire bars.
:
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a section of the fireplace of a puddling or other like
furnace, having the sides thereof of iron, perforated with holes for the passage
of air to the fuel above the fire bars. The sides are shown as being set back
or recessed, so that any melted matters running down from the roof and from
the upper parts of the sides will not run on the sides where the streams of
air enter, but will drop as soon as they come to the part'a; a'; but it is not
essential, when using iron, that the sides of a furnace (where the streams of
air come through) should be recessed or stand back. Figure 2, shows a
longitudinal section across the line A, B; Figure 3, a longitudinal section
across the line C, D; Fig. 8*, a longitudinal section across the line E, F ;
Figure 4, a transverse section across the line G, H; Fig. 4*, a transverse
section across the line I, J; and Figure 5, a plan in section of a puddling
furnace where perforated plates of iron are used for letting in streams of air
at the sides of a furnace above the fire bars, and the perforations are such as
I prefer; but the same may be varied, and other forms of plates, with perfora-
tions, may be used, and even bars of iron, with spaces between, may be
employed.
Having thus described the nature of my Invention, and the means of
performing the same, I would have it understood that what I claim is,―
First, the mode of constructing the fire places of furnaces when streams of
air are admitted at the sides or any of them, by recessing or setting back the
parts of the sides through which the streams of air pass:
Secondly, I claim the forming of the parts of sides of the fireplaces of
puddling and similar furnaces used for heating and melting iron, of perforated
plates of iron, and of iron in the form of bars:
And, thirdly, I claim the combining the arrangement of flues shown with
the use of iron sides of such fireplaces, whether perforated, or in the form of
bars.
In witness whereof, I, the said Alfred Dalton, have hereunto set my hand
and seal, this Fifteenth day of June, One thousand eight hundred and
ALFRED (L.B.) DALTON.
