Year: 1867

page_text: LETTERS PATENT to William Harrison, of Wharton Green, Winsford, in
the County of Cheshire, in the United Kingdom of Great Britain and
Ireland, Salt Manufacturer, for the Invention of "AN IMPROVED METHOD
OF CONSUMING SMOKE IN FURNACES."
Sealed the 4th June-1867, and dated the 20th April 1867.
COMPLETE SPECIFICATION filed by the said William Harrison at the
Office of the Commissioners of Patents, with his Petition and Decla-
ration, on the 20th April 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, in the
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

page_text: Drawings, in which the same letters of reference indicate similar parts, that
is to say:
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 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 Figure 5 by the 'letters B, B, B, B, and C, C; C, C, or B, B, G, F, B, B,
and C, C, H, I, C, C; or in Figure 2 by the letters A, B, C, D, or A, B, E,
F, C, D, may be taken up one or more flues, turned round, and be 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 side, as represented in
Figure 6 by the letters A, O, P, A, and D, D, M, N, back, as represented in
the same Figure by the letters A, A, A, A, and D, D, D, D, or A, A, O, P, A, A,
and D, D, M, N, D. D, bottom or top (with the proper quantity of air
admitted) through a flue or flues or culvert, as represented in Figure 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 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 may enter the flue or flues and then be met by the flame
and smoke from the furnace, as in Figure 5; or the smoke and flame from
the furnace, as represented in Figure 4 by the letters B, B, B, B, or
B, B, E, F, B, B, may enter a flue or flues wholly or partly carried through the
furnace, and be met at the entrance of the flue or flues by the flame and
smoke from the furnace, represented by the letters A, A, A, A, or A, A, O,
P, A, A, or as represented in Figure by the furnaces A, A, A, A, and
O, P, A, A, or as represented in Figure 7. 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 whose flame and smoke
meets the flame and smoke from the other furnace or furnaces, and 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; also openings
to admit air so that it may mix with the smoke before it comes to the flame
of the furnace. There may be openings in the flue or flues that pass through

page_text: 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
a 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.
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,
First, the flue or flues or culverts in the furnaces, no matter how carried
through the furnace.
Second, a combination of furnaces so that the smoke from one or more
furnaces may be consumed by one.
Third, a combination of furnaces so that they may consume the smoke from
each other.
In witness whereof, I, the said William Harrison, have hereunto set
iny hand and seal, this Sixteenth day of April, in the year of our Lord
One thousand eight hundred and sixty-seven.
WILLIAM HARRISON. (L.S.)
