Year: 1867

page_text: LETTERS PATENT to William Harrison, of Wharton Green, Winsford, in
the County of Cheshire, United Kingdom of Great Britain and Ire-
land, Salt Manufacturer, for the Invention of "AN IMPROVED METHOD OF
CONSUMING SMOKE IN FURNACES."
COMPLETE SPECIFICATION filed by the said William Harrison at the
Office of the Commissioners of Patents, with his Petition and Declaration,
on the 20th February 1867, pursuant to the 9th Section of the Patent
Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HARRISON, of Wharton Green, Winsford, in the County of Cheshire, United
Kingdom of Great Britain and Ireland, Salt Manufacturer, send greeting.
WHEREAS I am in possession of an Invention for "AN IMPROVED METHOD
OF CONSUMING SMOKE IN FURNACES," and have petitioned Her Majesty to grant
unto me, my executors, administrators, and assigns, Her Royal Letters Patent
for the same, and made solemn declaration that I am the true and first
Inventor thereof.
NOW KNOW YE, that I, the said William Harrison, do hereby declare
that the following Complete Specification, under my hand and seal, fully
describes and ascertains the nature of the Invention, and the manner in which
the same is to be performed, reference being had to the accompanying
Drawings, that is to say :-

page_text: My Invention relates to an improved method of consuming smoke in
furnaces, the merits of which are that it will give a greater amount of heat for
making salt, heating boilers, and such like applications, with a lesser quantity
of coals than can be obtained by the old method, and with little or no smoke;
that it is applicable to one or more furnaces; that the smoke from one or
more furnaces, as represented in Fig. 3 by the letters B, B, B, B, or B, G, F, B,
or in Fig. 2 by the letters A, B, C, D, or A, E, F, D, may be taken up one
or more flues, turned round, and brought again to the furnace or furnaces, or
to another set of furnaces, down one or more flues, and be turned out in a
furnace at the front, the side as represented in Fig. 4 by the letters D, D, M, N,
the back as represented in same Fig. 4 by the letters A, A, A, A, or A, O, P, A,
the bottom or the top (with the proper quantity of air) through a flue or flues
as represented in Fig. 3 by the letters D, I, C, A, wholly or partly in the other
furnace or furnaces, to be made of iron, fire-clay, bricks, or other material;
and it or they may enter the furnace or furnaces at the front, side,,back,
bottom, or top, and may cross the furnace in any direction that is desirable,
and may come out of the furnace or furnaces at the front, side, back, bottom,
or top; and it or they may be on a level with the furnace bars, raised above
them, or suspended in the furnace, according to the "quantity of heat required;
or the smoke from the furnace or furnaces, as represented in Fig. 3 by the
letters B, B, B, B, or C, C, C, C, or B, F, G, B, or C, H, I, C, may enter a
flue or flues wholly or partly carried through the furnace, as represented in
Fig. 3 by the letters A, A, A, A, (the smoke from which enters the flue or
flues without going round up the other flues) and be met by the flame and
smoke from the furnace, as represented in Fig. 3 by the letters A, A, A, A,
that does not go round, that is to say, the first furnace that the smoke comes
to. There are doors or openings to the flues for supplying the smoke with the
proper quantity of air in the furnace in which the smoke is turned loose, or in
the furnace, the flame and smoke of which meets the smoke from the other
furnace or furnaces in the flue or flues in the furnace at the front, side, back,
bottom, or top, or behind the furnace bars out of the ash-pit, or through the
jambs between the furnaces leading into the flue or flues which pass through
the furnaces. There may be openings in the flue or flues that pass through
the furnaces for the heat from the fire to pass into the flue so that it may
attain a greater heat, and the smoke thus mixed with air ignites and gives off
great deal of heat in the flue or flues that lead to the chimney; and the flue
or flues are provided with a damper or dampers at the end where it or they
go in or come out of the furnace to check the escape of smoke when the fires
are mended with fresh coals. .

page_text: Having thus described the nature of the said improvements, and the manner
of carrying the same into effect, I would have it understood that I do not
confine myself to the precise details above enumerated, as these may obviously
be modified without departing from the principle of the Invention according
to the special construction and intended applications of the furnaces in which
they are adopted; but what I claim is,—
1°. The disposition and arrangement of the furnaces according to my method
so as to have any number of furnaces combined together.
2°. The consuming of the smoke from all the furnaces by one of them.
3º. The use as a heating medium of the smoke consumed on coming out of
the flue or flues in the furnace in the flue leading to the chimney or chimneys.
In witness whereof, I, the said William Harrison, have hereunto set my
hand and seal, this Nineteenth day of February, in the year of our
Lord One thousand eight hundred and sixty-seven.,
WILLIAM HARRISON. (L.B.)
