PROVISIONAL SPECIFICATION.
Improvements in Apparatus for the Consumption of Smoke.
1, HUDSON WILSON, of Water Pitts Mill, Windhill, Shipley, in the County of
York, Worsted Spinner, do hereby declare the nature of this invention to be as
follows:-
My invention relates to certain improvements in the construction of apparatus
in such a manner as to be suitable for combining with boiler and other furnaces,
and has for its object, the arrangement of the apparatus so that smoke from the
coal or other fuel is to a great extent consumed within the furnace or flues, and
thereby to prevent volumes of smoke being emitted from the chimney.
I accomplish my object in the following manner :-The space in front of the
furnace beneath the fire bars is fitted with a plate for the exclusion of the atmo-
spheric air required for the combustion of the fuel. The air is collected and
distributed in a novel manner and is accomplished by means of a steam pipe
which is conducted from the boiler through the heated flues, by which the steam
passing through same is superheated, and is allowed to escape through a jet into
a pipe having one end open to the atmosphere, the other end being connected to a
box having a number of tubes or hollow bars attached thereto or a combination
of both tubes and hollow bars which are also connected to another box placed
behind the furnace door frame.
The air is forced through the tubes by the steam jet and in passing, is heated to
a high temperature and allowed to escape from the last mentioned box into the
space under the fire bars, thus supplying heated air for the combustion of the fuel
and prevention of the formation of smoke.
The box behind the furnace door frame is provided with an outlet above the
fire and is fitted with a door opening inwards, which may be opened or closed when
desirable; opposite this door is another steam jet and a pipe coupled to a supply.
of heated petroleum which, on opening the steam jet causes the petroleum to enter
the furnace in the form of spray and is there ignited, thereby assisting in the
prevention, in the formation, of, or in the combustion of smoke.

COMPLETE SPECIFICATION.
Improvements in Apparatus for the Consumption of Smoke.
I, HUDSON WILSON, of Water Pitts Mill, Windhill, Shipley, in the County of
York, Worsted Spinner, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My invention relates to certain improvements in the construction of apparatus
in such a manner as to be suitable for combining with boiler and other furnaces,
and has for its object the arrangement of the apparatus so that smoke from the
coal or other fuel is to a great extent consumed within the furnace or flues, and
thereby to prevent volumes of smoke being emitted from the chimney.
In order that my invention may be fully understood I will describe the same in
detail by making reference to the accompanying sheet of drawings in which
Fig. 1 represents a longitudinal section through a portion of a steam boiler with
my improvement added thereto.

page_text: Fig. 2 is a front view partly in section.
Figs. 3 and 4 are enlarged details.
In the front end of the furnace A of a steam boiler B. I secure
a hollow
box C. to which an ordinary fire door D may be mounted, or to a plate in the
usual manner, in which case the hollow box C rests upon a dead plate. At the
back end of the furnace supporting the bridge E is a second hollow box F.
provided at its front side with a hinged door G. Air is admitted under the
furnace bars J which passes into the box F and through openings H into and
through the hollow fire bars J where it is heated, then to the hollow box C at
the front of furnace, from which it escapes through the opening C¹ on to the
fire; thus by these means air is heated and supplied to the furnace for the more
effectual combustion of the fuel and the prevention of smoke.
To the back end or other convenient part of the boiler I connect a steam
pipe K. and conduct same through the heated boiler flue L. by which the steam
on passing through same is superheated, the pipe is conducted under the fire
bars J. and the superheated steam delivered through a jet M into the hollow
box F. thereby encouraging the current of air to enter the said box and pass
through the fire bars J to the hollow box C. from which it escapes and is deflected
by the plate P fixed in front of the opening.
In order to assist in the consumption of smoke immediately after supplying
the furnace with fuel, I may secure a tank or cistern N containing petroleum
to the front of the boiler or in any convenient position, the said tank having a
pipe N' for the discharge of the oil. The steam pipe K. is continued by a
branch K provided with a tap O. and terminates in the hollow box C. Upon
the said tap being opened, the steam escaping from a jet at the end of pipe K'
in the hollow box C. it causes the petroleum to be discharged on to the fire in the
form of a fine spray, and is there ignited, thereby assisting to ignite the gases
emitted from the fuel immediately after supplying the furnace with fuel, and before
the latter is burnt through.
To the hinged door G of the hollow box F. 1 attach a rod R for opening or
closing same when required, which may be connected to any well known automatic
apparatus for closing the door on the expiration of any predetermined period
of time.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same may be performed, what I declare and claim as
my invention is-
1. In a furnace the combination of the hollow box F with the hollow fire bars J
and hollow box C provided with an opening for allowing the beated air to escape
into the furnace all arranged substantially in the manner as described and for the
purpose as herein before set forth.
2. The combination of hollow fire bars J. with a distributing box C at the front
end of the furnace so constructed as to deflect the heated air on to the top of the
fuel laying on the fire bars for the purpose as hereinbefore described.
