Improvements in the Mode, Means, and Apparatus for Treating
Smoke for the Extraction of the Carbon and other Residual
Products Resulting from Imperfect Combustion.
I, WILLIAM MESSE WARD, of Newton Villa Claremont Road, Handsworth, in
the County of Stafford, Gentleman, do hereby declare the nature of my said
invention to be as follows:-
My invention has for its object improvements in the mode, means, and
apparatus, for treating smoke for the extraction of the carbon, and other residual
products resulting from imperfect combustion. Attempts having the same object
in view have been made by previous inventors such for instance as by Samuel
Elliott in his Specification No. 12,460 A.D. 1889 and subsequently, but my present
invention has for its object a very much more simple mode and apparatus for
accomplishing the same result, the nature of which I will now proceed to make
known:-
I form in the flue leading to the chimney, or immediately beyond the junction
of a number of flues, a chamber of sufficient capacity to deal with the smoke
effectively without curtailing the chimney draft, or the effectiveness of the flues,
and this chamber may be constructed or lined with brickwork, wood, iron, or such like
material or substance as will best resist the effect of acid contained in, or formed
by the treatment of the smoke. My chamber is formed with a recessed bottom
for holding water and with suitable doors or covers communicating therewith for the
abstraction of the residual products obtained from the smoke and for the
examination of the inside generally. Inside this chamber or in its outside walls is
hung a beater, in such a manner that a portion of the beater is immersed in the
recessed bottom of the chamber. The beater is revolved in a direction towards the
current of the smoke in the flues, so that the arms or vanes of the beater carry down
the smoke or fumes into, and through the chamber of water or other liquid
through which the smoke is thus forced and carried by the revolving beaters for
the extraction of the residual products it contains, and so as to wash and purify
the smoke by its contact with the water or its equivalent liquid. The beater is
constructed with external vanes or arms, and is driven rapidly so that a certain
amount of water is continually carried round by the arms or beaters and delivered
on the side where the smoke enters. The flue or flues may be so formed' at their
delivery end, into the chamber as to deliver the smoke or fumes in the direction of
the recessed bottom thus assisting the easy passage through the chamber to the
chimney. Over or around the revolving beater I may fix removeable covers, or
sieves, of a curved or other form, which may be either agitated or cleaned with a
brush or brushes, either constantly, or from time to time. It will thus be seen
that the gasses or smoke is operated upon by my plan without injury to the
chimney, and without the intervention of a blower, fan, exhauster, or other inter-
mediate arrangement for drawing the smoke from the chimney after its entrance

Improvements in the Mode, Means, and Apparatus for Treating
Smoke for the Extraction of the Carbon and other Residual
Products Resulting from Imperfect Combustion.
I, WILLIAM MESSE WARD, of Newton Villa, Claremont Road, Handsworth, in
the County of Stafford, Gentleman, do hereby declare the nature of my said
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 for its object improvements in the mode and means and
apparatus, for treating smoke for the extraction of the carbon and other residual
products resulting from imperfect combustion. Attempts having the same object
in view have been made by previous inventors such for instance as by Samuel
Elliott in his Specification No. 12,460 A.D). 1889 and subsequently, but my present
invention has for its object a very much more simple mode and apparatus for
accomplishing the same result, the nature of which I will now proceed to make
known-
I form in the flue leading to the chimney or immediately beyond the junction of the
flue or a number of flues, a chamber of sufficient capacity to deal with the smoke
effectively without curtailing the chimney draft, or the effectiveness of the flues,
and this chamber may be constructed or lined with brickwork, wood, iron, or such like
material or substance as will best resist the effect of acid contained in or formed
by the treatment of the smoke. My chamber is formed with a recessed bottom
for holding water and with suitable doors or covers communicating therewith for the
abstraction of the residual products obtained from the smoke and for the
examination of the inside generally. Inside this chamber or in its outside walls is
hung a beater in such a manner that a portion of the beater is immersed in the
recessed bottom of the chamber. The beater is revolved in a direction towards the
current of the smoke in the flues, so that the arms or vanes of the beater carry down
the smoke or fumes into and through the chamber of water or other liquid
through which the smoke is thus forced and carried by the revolving beaters for
the extraction of the residual products it contains, and so as to wash and purify
the smoke by its contact with the water or its equivalent liquid. The beater is
constructed with external vanes or arms and is driven rapidly so that a certain
amount of water is continually carried round by the arms or beaters and delivered
on the side where the smoke enters. The flue or flues may be so formed at their
delivery end into the chamber as to deliver the smoke or fumes in the direction of
the recessed bottom thus assisting the easy passage through the chamber to the
chimney. Over or around the revolving beater I may fix removable covers
sieves of a curved or other form, which may be either agitated or cleaned with a
brush or brushes either constantly or from time to time. It will thus be seen
that the gasses or smoke is operated upon by my plan without injury to the
chimney, and without the intervention of a blower, fan, exhauster, or other inter-
mediate arrangement for drawing the smoke from the chimney after its entrance
thereto, and that a considerable saving in plant and power is thus effected and
much greater simplicity in the process obtained.

page_text: In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto three sheets of drawings illustrating
an example of the same, but it will be distinctly understood that the arrangement
will be suited to the particular position of the boilers or other furnaces and the
chimney, but the principle of conducting the operation by means of the chimney
without a fan exhauster, etc., will be the same.

beaters or arms R are constructed from frame work or any material most suitable
for the purpose and best adapted to withstand the chemical action of the liquid
or residual products obtained from the smoke or fumes as they pass through the
water in the washing process. These arms are by preference made by framing
with nanels perforated and mounted in recesses in the framing and the panels
may of course be of any desired size and shape to suit the chamber. Over the top
of the revolving beaters I place perforated covers or scrubbers C which may be
curved. These scrubbers may if desired have a motion imparted to them, but in
any case the resultant fumes remaining after the washing process find their way
through these covers into the upper chamber and thence through the flue 13
into the chimney S without the intervention of any fan or exhauster by the
simple draft due to the height of the chimney which is due to all boilers furnaces
and similar apparatus where fuel is consumed.
It will be observed that the smoke enters the chamber K from the flue F in
the direction of the arrows which indicate the direction in which the beaters R
revolve and it is then carried through the water W at the bottom of the chamber K
which is kept as shallow as possible compatible with the efficiency of the apparatus.
While the operation proceeds water issues through the inlets k which may be
perforations in fire brick or a perforated pipe. Water is also discharged on to
the perforated scrubbers or covers through the pipe or pipes w in such a manner
that the smoke is effectually robbed of its objectionable properties which are
deposited at the bottom of the chamber K from whence it is drawn into the tank T
through the pipe t¹. The lid E gives free access to the chamber K and to the
beaters and apparatus generally, but I may add supplimental doors to any part
of the chamber or apparatus as may be found necessary. In case of accident the
damper may be dropped and the damper f5 raised, so that the smoke would
then be carried direct to the chimney S by the bye pass flue 13. It will be thus
seen that I do not use either a fan exhauster or hollow shaft and that my improved
mode of dealing with the smoke is of such a character that the beaters carry the
smoke onwards towards the chimney.
Having now particularly described and ascertained the nature of
my said
invention and in what manner the same is to be performed, I declare that what
I claim is:―
CLAIMS.
First. The improvements in the mode, means and apparatus for treating smoke
for the extraction of the carbon and residual products resulting from imperfect
combustion by means of a beater mounted in a chamber K in the flue F the draft
being operated in the usual manner by the chimney S substantially as herein set
5 forth and shown upon the three accompanying sheets of drawings.

page_text: Second. In apparatus which is the subject of the first claim the chamber K
with the beaters and shaft mounted therein and operated as herein set forth by
the chimney draft.
Third. In apparatus which is the subject of the first and second claims the
perforated covers or scrubbers C whether stationary or active substantially as 5
