IM- PROVEMENTS IN FURNACES OR FIRE-PLACES
Year: 1843

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Civil Engineer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Fourth day of November, in the seventh year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William Edward Newton, Her especial licence, full power, sole privilege and
authority, that I, the said William Edward Newton, my executors, adminis-
trators, and assigns, and such others as I, the said William Edward Newton,
my executors, administrators, or assigns, should at any time agree with, and
no others, from time to time, and at all times during the term of years therein
mentioned, should and lawfully might make, use, exercise, and vend, within
England, Wales, and the Town of Berwick upon Tweed, my Invention of "IM-
PROVEMENTS IN FURNACES OR FIRE-PLACES," being a communication from a foreigner
residing abroad; in which said Letters Patent is contained a proviso obliging
me, the said Williamı Edward Newton, by an instrument in writing under my
hand and seal, particularly to describe and ascertain the nature of the said
Invention, and in what manner the same is to be performed, and to cause the
same 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, I, the said
William Edward Newton, do hereby declare that the nature of the said Inven-
tion and the manner in which the same is to be performed, is particularly
described and ascertained in and by the following description thereof, reference
being had to the Drawing hereunto annexed and to the letters and figures
marked thereon (that is to say) :-
The Invention of Improvements in Furnaces or Fire-places, which has been
communicated to me by my correspondent abroad, and for which I have
obtained Her Majesty's Royal Letters Patent as aforesaid, consists of a novel
construction or form of fire bars intended to constitute the grate of a furnace
whereby a considerable economy is effected and other advantages are obtained.
The peculiar form of fire bars which is intended to be claimed under this
Patent is shewn in the Sheet of Drawings hereunto annexed, in which Fig. 1
represents an end elevation of one of the improved fire bars, and Fig. 2 an
end or front elevation of several of these bars arranged or combined in the
manner they would be placed to constitute a grate; Fig. 3 is a sectional
representation of the same taken transversely across the bars; and Fig. 4
represents the under side of two or a pair of the bars. It will be seen upon
referring to Figs. 2 and 3, that the upper surfaces of the bars are inclined at
an angle to the horizon and are arranged in pairs, the surface of each single
bar being placed at an opposite angle to its fellow or adjoining one. By these
means the surface of the grate or bed of the furnace is indented, so that a
portion of the fuel lies between the bars in angular recesses and the remaining
part of the fuel above them. It will also be seen on inspecting the sectional
view, Fig. 3, that the inclined bars are furnished with feet a, a, a, or deep bars
below for the purpose of affording strength and supporting them in the places
on the cross bar b, b, Fig. 2, and that the lateral edges of the bars are set at a
little distance apart, so as to form long narrow slits or openings c, c, and d, d,
between them for the admission of air from the ash pit through the grate in
order to support the combustion of the fuel. By means of this construction
and arrangement of bars, air is admitted to the interior of the fire at two
different altitudes, and the fuel is more regularly and economically consumed
than in grates of the ordinary construction. When the fire bars are arranged
in the proper manner on the cross bars b, b, they are retained in their
respective places and proper positions by means of the end plates e, e, e, Fig. 2,
one of which is shown detached at Fig. 5, and which also rest on the cross
bars b, b.
Having now described the Invention that has been communicated to me as
aforesaid, I wish it to be understood, that I am aware that grates have been

page_text: already constructed in which the fuel rests on the angular sides of the bars. I
do not, therefore, intend to claim this as constituting any part of the present
Invention except when the same is combined with the other parts of the
improvements; but I claim as the Invention secured to me by the herein-before
in part recited Letters Patent, constructing the grates of furnaces or fire-places
in such a manner that the air to support combustion may be supplied between
the fire bars at different planes, altitudes, or elevations, as above described.
In witness whereof, I, the said William Edward Newton, have hereunto
set my hand and seal, this Fourth day of May, in the year of our Lord
One thousand eight hundred and forty-four.
