PROVISIONAL SPECIFICATION.
A New or Improved Method of and Means for Preventing the
Emission of Smoke from Mill or other Chimneys.
I, FREDERICK ROBERT JONES of Lane Ends, Crosland Moor, Huddersfield, York-
sbire, District Registrar of The High Court of Justice, do hereby declare the nature
of this invention to be as follows:-
My invention has reference to a new or improved method of and means for
preventing the emission of smoke from mill or other chimneys, the object thereof
being to keep the atmosphere free from the soot and impurities with which it is now
charged in consequence of the large amount of dense black smoke which is now
emitted from mill chimneys and from the chimneys of houses and other buildings.
In order to carry out my invention I employ two or other number of pipes, each
of which communicates with the interior of the chimney or flue, and are so arranged
that the mouths of the said pipes are opposite each other. One of these pipes I
connect to the exhaust steam pipe or to any other convenient source from which
steam may be obtained, and a valve is employed so that steam may be blown through
the said steam pipe whenever desired. The second pipe is connected with the main
drain or other suitable conduit.
When smoke is ascending the chimney or flue, the valve on the steam pipe is
opened, thereby allowing steam to be blown therethrough, which, coming in contact
with the ascending smoke carries or forces it into the pipe on the opposite side and as
the steam condenses it is absorbed by the anhydrous or dry substances of the smoke,
and becomes thereby moist and heavy and descends or falls down the said last
mentioned pipe and is deposited into the drain. Where desired, suitable tanks could
be made to receive or collect the deposit from the chimney, from which tanks it
could be easily taken and utilized for manuring purposes.
By the method and means above described all the smoke passing from the fire up
the chimney or flue will be arrested, and conveyed in a moist or paste form into the
drain; and any smoke which may escape through the steam and pass from the
chimney will be in a filtered or purified state in consequence of having been brought
into contact with the steam, whereby the atmosphere will be kept free from the dirt
and impurities at present conveyed thereto in the form of smoke, and will thereby be
rendered much healthier.

COMPLETE SPECIFICATION.
A New or Improved Method of and Means for Preventing the
Emission of Smoke from Mill or other Chimneys.
I, FREDERICK ROBERT JONES, of Lane Ends, Crosland Moor, Huddersfield, York-
shire, District Registrar of the High Court of Justice, 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 has reference to a new or improved method of and means for
preventing the emission of smoke. from. mill or other chimneys, the object thereof
being to keep the atmosphere free from soot and impurities with which it is now
charged, by reason of the large amount of dense black smoke emitted from mill
chimneys and from the chimneys of houses and other buildings.
In order to carry out my invention I employ two or other number of pipes, each of

page_text: which communicates with the interior of the chimney or flue, and are so arranged
that the mouths or orifices of the said pipes are opposite each other. One or more of
these pipes are connected to the boiler or to the exhaust steam pipe, and a valve is
employed so that steam may be blown through the said pipe or pipes whenever
desired. The remaining pipe is connected to the fire box of the boiler, or with the
underside of the fire, or it may be connected to a tank or receiving vessel. When
smoke is ascending the chimney or flue, the valve in connection with the steam pipe
is opened, thereby allowing steam to be blown therethrough, which, coming into
contact with the ascending smoke, arrests or intercepts such smoke and carries or
forces it into the orifice and down the pipe on the opposite side.
To enable my invention to be more fully understood, I herein make reference to
the annexed sheets of drawings wherein Fig. 1 is sectional elevation of a chimney
having my improvements applied thereto, and Fig. 2 is plan of same taken on
line 1-2 of Fig. 1. Figs. 3 and 4 are similar sectional elevation and plan views
respectively, of a modified arrangement of my improvements.
a is the chimney shewn in section, and 6 is the flue leading from the furnace or
fire to the lower portion of the interior of the chimney, and by which the smoke is
conveyed to the said chimney. C is a vertical steam pipe, the lower end of which is
connected to the steam boiler, exhaust steam pipe, or other source of supply near at
hand, the upper end of such said pipe being provided with two branch pipes d and e,
of unequal lengths, the piped passing through the stone or brickwork, and terminating
just within the chimney, so that its open end or orifice commands the area thereof;
the pipe e also passes through the stone or brickwork and extends across the shaft
near to the opposite side of the chimney; both pipes being inclined or converging
towards each other with their open ends pointing or being directed to one common
centre. On the contrary or opposite side of the chimney is a pipe f of larger
diameter than the pipe c, the upper end of which said pipe fis bent inwards at right
angles, and is inserted into a corresponding opening in the stone or brickwork of the
chimney, formed directly opposito the mouths of the branch pipes de. Connected in
any suitable part of the pipe c is a valve g which is opened and closed by means of
hand wheel, or by a key, for the admission or otherwise, of steam.
When dense smoke is being given off by the fire, the valve g is opened to allow
steam to pass and issue from the open ends of the branch pipes d and e, such said
steam escaping in the form of spray. The jet of steam from the pipe d intercepts
the ascending smoke and forces it across the chimney into the pipe f, whilst the jet of
steam from the pipe e assists in drawing the smoke from the chimney into the pipe f
and further forces such smoke down the said pipe, by which it may be conducted to
the fire to be consumed; or if the intercepted smoke is too moist by the absorption of
the condensed steam, I may pass the smoke through an ordinary condenser and thus
render it in a fit condition to be consumed by the fire.
Instead of consuming the smoke, I may deposit it into a tank or receiving vessel,
from which it can be taken and treated for manuring or for other purposes, such as
the production of gas and ammonia.
In Figs. 3 and 4, I shew that a single jet of steam may be employed for arresting
or intercepting the ascending smoke and forcing it into the pipe f. In this case, one
of the branch pipes is dispensed with, or both are removed, and the upper end of the
pipe c is bent and passed through the wall of the chimney somewhat as shewn in the
drawings.
The means and method herein described for preventing the emission of smoke
from mill chimneys, will answer for all descriptions of chimneys to which my improve-
ments may be applied, but in the case of chimneys connected with dwelling houses,
it would be more economical to supply steam to a number of such chimneys from one
boiler.
Although I have herein described the use of steam for intercepting smoke and
forcing it into a fall pipe as it ascends the chimney, it will be obvious that air, water,
or other suitable gas or liquid could be employed and blown or drawn across the
chimney by fan, bellows, or suction pump, either in conjunction with or independently

page_text: of the jet or jets of steam, for the purpose of producing the same result as that
already described with reference to steam alone; but as steam is nearly always at
hand, and no special means required to obtain it, I have therefore specified its use in
preference to other gases or liquids.
The arrangement and construction of the several pipes herein referred to may be
altered or varied to suit various descriptions of chimneys, and if found necessary,
three or more jets of steam, or other gas or liquid, may be employed.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is :-
Firstly. The use and employment of a jet or jets of steam or other gases or liquids
for arresting or intercepting smoke and forcing it into a fall pipe, as it ascends a
chimney, in the manner substantially as herein shewn and described.
Secondly. In combination with the steam or blow pipes for preventing the emission
of smoke from chimneys, of a pipe or its equivalent for receiving and conveying
away the intercepted smoke, substantially as herein described.
Dated this 26th day of August 1889.
