IMPROVEMENTS IN APPARATUS FOR ENSURING THE COMBUSTION OF SMOKE
Year: 1876

page_text: LETTERS PATENT to William Cordingley, of Wakefield, in the County of York,
Millwright and Engineer, for the Invention of "IMPROVEMENTS IN APPARATUS
FOR ENSURING THE COMBUSTION OF SMOKE."
Sealed the 5th January 1877, and dated the 17th July 1876.
PROVISIONAL SPECIFICATION left by the said William Cordingley at the
Office of the Commissioners of Patents on the 17th July 1876.
WILLIAM CORDINGLEY, of Wakefield, in the County of York, Millwright and
Engineer. "IMPROVEMENTS IN APPARATUS FOR ENSURING THE COMBUSTION OF
SMOKE."
This Invention has for its object the construction and application of improved
and inexpensive appliance designed to ensure combustion of smoke arising from fuel
supplied to the furnaces of steam and other boilers.
The bottom portion of the furnace door the whole of its width is cut away, or
a longitudinal slot or opening is formed along the lower portion of the door, (or the
opening may be through the dead plate,) this affords a passage for the entrance of
air to the furnace.
Immediately within the furnace, and by preference attached to the door above
the clongated air passage referred to, is an adjustable deflecting plate, in length
equal to the air passage, so that as the air enters the opening it impinges against
the deflecting plate and is diverted and turned downwards upon the fuel, the air
mingles with the gases, the whole are consumed, and the escape of smoke is pre-
vented.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said William Cordingley in the Great Seal Patent Office on the 17th January
1.877.

page_text: Figure I. is a front elevation of a two-flue boiler having my improved apparatus
applied thereto.
Figure 2 is an elevation of one-flue door and improved apparatus drawn to a
larger scale, say, about one-fourth full size.
Figure 3 is a section on the line A, B, of Figure I.
Figure 4 is a section on the line CD; at C is the furnace door, the lower portion
of which is cut away when applying the Invention to existing furnace doors.'
When new doors are to be used they will be of less depth, so that in all cases the
passage D for the entrance of air to the furnace will be provided, and it must be
understood that in all cases where the doors "C" are (as shewn in the Drawings) of
less width than the furnace bars, the air passages must be continued, as shewn at
E and F, in order that by the combined use of such air passage or passages, and
the deflecting plates G, G, the air on entering impinges and is diverted and turned
downwards and upon the fuel nearest the dead plate over the width of the fuel.
The several openings are provided with doors H, H, by the use of which the
amount of air entering may be regulated and controlled. If the air passage D
is by way of an alongated slot found in the dead plate such plate and slot must,
as already herein directed and for reasons assigned be of the whole widther of the bars.
Having thus described the nature and particulars of this my said Invention,
together with the manner in which the same is to be or may be performed or carried
into practical effect, I would have it understood that I do not lay claim either to
the use of an air passage through the door of a furnace, nor to the use of a
deflecting plate; but what I claim is, the use and employment of an elongated air
passage or air passages in combination and conjunction with the deflecting plates
when arranged and constructed in the manner and for the purposes herein described
and illustrated by Drawings.
In witness whereof, I, the said William Cordingley, have hereunto set my
hand and seal, this Fourth day of January, in the year of our Lord One
thousand eight hundred and seventy-seven.
Witness,
JOHN WHITAKER,
Secretary to the Gas Company,
Wakefield.
