PROVISIONAL SPECIFICATION.
Improvements in Smoke-consuming and Smoke-utilizing Apparatus.
I, GEORGE HEWITT, of 24, Attercliffe Common, Sheffield, in the County of
York, Merchant, do hereby declare the nature of this invention to be as follows:-
My present invention relates to means or apparatus employed for consuming and
utilizing smoke and has for its object means for burning the smoke which in
ordinary cases would leave the furnace fire box grate or combustion chamber
unconsumed and would pass out of the chimney or vent thereby generally causing
a smoke nuisance. To attain the object therefore of my invention I fix or secure
in a suitable part of the furnace flue fire box or combustion chamber the suitable
part preferably being in a place immediately beyond the burning fuel-a perforated
box plate or plates which is or are arranged in such a manner that the unconsumed
smoke passing from the fire is somewhat retarded or baffled in its passage towards
the chimney or vent and I so arrange said perforated box plate or plates that it
or they will not prevent the requisite draught needed for the support of combustion
within the furnace.. Immediately in front of the said perforated box plate or plates
I arranged two or more pipes which terminate in nozzles which are placed in such
a manner that they direct certain elements hereinafter specified in due proportions
towards said box plate or plates. One such pipe communicates with a cistern or
reservoir containing water under pressure and another pipe communicates with a
cistern or receptacle containing paraffin or other combustible oil or element.
This paraffin receptacle is preferably arranged with a suitable air pump in
order that air may be pumped into the same and mix with the paraffin or other
oil so that the same may be supplied to my improved apparatus in as inflammable
condition as possible.
Suitable taps are arranged between the water reservoir and furnace and between
the paraffin receptacle and furnace in order that the supply of each element may
be controlled automatically or at will. The water is caused to flow towards the
perforated box plate or plates in the form of spray by which means the smoke is
condensed or deposited and the paraffin or oil and air is used in order to burn up
such deposit or soot within the perforated box plate or plates. By this means the
smoke which would otherwise escape and cause a nuisance is entirely consumed
and thereby utilized for creating further heat within the furnace as will be well
understood.
Where preferred the receptacle containing the paraffin or oil may also contain
water and the whole may be mixed up with the air and supplied to the front of
said perforated box plate or plates in the form of spray in this case the separate
water reservoir may be dispensed with.

COMPLETE SPECIFICATION.
Improvements in Smoke-consuming and Smoke-utilizing Apparatus.
I, GEORGE HEWITT, of 24, Attercliffe Common, Sheffield, in the County of
York, Merchant, 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 present invention relates to means or apparatus employed for consuming and
utilizing smoke and has for its object means for burning the smoke which in

page_text: ordinary cases would leave the furnace fire-box grate or combustion chamber
unconsumed and would pass out of the chimney or vent thereby generally causing
a smoke nuisance.
In order to attain the object before referred to I employ the means and
apparatus hereinafter more particularly described by the aid of the accompanying
sheet of drawing in which
Fig. I is a longitudinal sectional elevation of a furnace arranged in accordance
with my present improvements and
Fig. 2 is a front view of the same.
Fig. 3 is a longitudinal sectional elevation of a furnace arranged with a modi-
fication of my present improvements and
Fig. 4 is a cross sectional elevation taken on line a a of said Fig. 3 and
Figs. 5, 6 and 7 are longitudinal sectional elevations of the bridge part of a
furnace representing various ways of arranging the perforated box plate or plates.
Like letters of reference denote corresponding parts in each view.
I fix or secure in a suitable part of the furnace flue fire-box or combustion
chamber B-the said suitable part in most cases being preferably in a place
immediately beyond the burning fuel-a perforated plate as shown at Figs. 1
and 2 or plates C as shown at Fig. 7 or suitable perforated boxes C as shown at
Figs. 3, 4 and 6 and in each case the said box boxes plate or plates C is or are
so arranged that the unconsumed smoke passing from the fuel or fire D is some-
what retarded or baffled in its passage thereby towards the chimney or vent but
the said box boxes plate or plates C are also so arranged that they will not
prevent the requisite draught needed for the support of combustion within the
furnace B. Each plate or box C-is supplied with crude petroleum paraffin or
other like oil in proportion consistent with the size of the fire and the quality of
the fuel being burned in the furnace B and each plate and box C is also where
found of advantage supplied with a certain amount of water the supply of both oil
and water being varied to suit circumstances as will be well understood. The
paraffin crude-petroleum or other like oil is conveyed to the plate or box C by
the pipe G-Figs. 3 and 4-which communicates with the supply tank H and the
water is conveyed to each said plate or box C by the supply pipe J which leads
to a suitable reservoir K.
Where preferred the paraffin receptacle H may be arranged with an ordinary
air-pump P and a required quantity of water may be mixed with said paraffin and
air pumped into the receptacle H so that oil and water will be supplied through
one and the same pipe G to the plate C as shown at Fig. 1.
Suitable taps and k' are situated between the reservoir K and the furnace B
and between the petroleum receptacle H and furnace B in order that the supply
of each substance may be controlled by any ordinary automatic appliance or
at will.
It is preferable that the water and oil should impinge in or on each box or
plate C in the form of spray and for this purpose it will be obvious that any
ordinary perforated nozzle such as a-Fig. 7-may be fitted to the discharge ends
of the pipes G and J respectively.
By the application to furnaces which burn solid fuel of my hereinbefore
described improvements the smoke is condensed or deposited upon the plate or
box C and the paraffin or other oil mixes therewith and by the aid of the heat in
said plate or box C the mixture is burnt and the smoke consequently prevented
leaving the furnace B unconsumed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. In apparatus for consuming or utilizing smoke the use of a perforated plate
or box C arranged immediately beyond or thereabouts of the burning fuel D and

page_text: supplied with paraffin crude-petroleum or other like oil intermixed or otherwise
with water and atmospheric air substantially as described and in part set forth in
the accompanying drawings.
