PROVISIONAL SPECIFICATION.
Improvements in Means for Consuming Smoke.
I, RICHARD CUNLIFFE, of 61, Darby Road, Weaste, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in means for consuming sinoke and has
for its object to perform the same in a more effective and simple manner than
heretofore has been the case.
To this end I form behind the ordinary fire bridge a second combustion chamber,
by employing at a suitable distance apart thereof, a porous bridge and admitting
between the said bridges a mixture of super-heated air and steant from a jet or jets
suitably arranged.
The said porous bridge I may form of any suitable fire-proof material, in such a
manner as to leave an opening in the flue communicating with the space below the
fire-bars.
The said jet or jets consist of a pipe arranged in communication with the steam
space of the generator and injector like with another pipe employed in the fire
space of the furnace, in such a manner that the steam from the generator enters and
draws fresh air through the said pipe, which air and steam in its passage to the
aforesaid second combustion chamber gets super-heated by the furnace heat.
Dated this 27th day of August 1891.

COMPLETE SPECIFICATION.
Improvements in Means for Consuming Smoke.
I, RICHARD CUNLIFFE, of 61, Darby Road, Weaste, in the County of Lancaster,
Engineer, 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 :-
This invention relates to improvements in means for consuming smoke and has
for its object, to perform the same in a more effective and simple manner than
heretofore has been the case.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings, representing a longitudinal section of
a boiler fitted with my improved means for consuming smoke.
In carrying out my invention, I form behind the ordinary fire bridge a, a second
combustion chamber b, by employing at a suitable distance apart thereof, a porous
or perforated bridge and admitting between the bridges a & c a mixture of super-
heated air and steam from a jet or jets d suitably arranged.
The porous or perforated bridge c I may form of any suitable fire-proof material,
in such a manner as to leave an opening in the flue ƒ corresponding with the
space g below the fire-bars h.
If deemed necessary I may employ more than one of the said porous or perforated
bridges o, so as to form more than one of the said combustion chambers, as shown
in dotted lines.
The air and steam jet or jets d I form respectively by arranging a pipe d², one end
of which is in communication with the steam space i of the generator and the other
end injector like with the pipe employed in the fire space k of the furnace, in such
a manner that the steam from the generator enters and draws fresh air through the

page_text: pipe, which air and steam, in its passage to the second combustion chamber b,
gets super-heated by the furnace heat.
By preference I employ two of the said air and steam jets d, one near each side
of the furnace flue f.
Having now particularly described and ascertained. the nature of this inven-
tion and in what manner the same is to, be performed;. I declare that what I
claim, is-
"In means for consuming, smoke."
1st. The general arrangement and combination of parts constituting my improve-
ments operating substantially as and for the purpose specified.
2ud. The employment of a jet or jets d for the admittance of superheated air and
steam behind the fire bridge a, substantially as and for the purpose set forth.
Dated this 27th day of May 1892.
