A communication from abroad by the INTERNATIONAL SMOKE CONSUMER COMPANY,

Street, in the City of Boston, in the State of Massachusetts, United States of
America.
I, ALFRED GFORGE BROOKES, of 55 & 56, Chancery Lane, in the County of
London, Chartered Patent Agent, do hereby declare the nature of this invention
and in what manner the same 18 to be performed, to be particularly described and
ascertained in and by the following statement
-
This invention is for improvements in means or apparatus known as "smoke
consumers," having for its object the provision of means for consuming the smoke,
and at the same time economising the consumption of the fuel by the heat
developed in the process of the smoke consumption, the invention also including
means for deadening the noise usually accompanying this class of devices, and
also includes further improvements which will be mentioned and explained herein-
after
The details of construction of the invention, the operation and further advantages
thereof, will appear more fully in the course of the following description, and the
invention will be more particularly defined in the appended claims, reference being
had to the accompanying diawings also formung part of this specification
In the diawings in which are shown a preferred embodiment of the invention,
Fig 1 18 a vertical longitudinal section of a furnace provided with my apparatus,
the latter being shown in central, vertical longitudinal section
Fig 218 a side elevation thereof, parts being bioken away, in order more clearly
to show the construction
Fig 3 is a central horizontal section thereof
The furnace A having a giate a, steam pipes a¹, boiler a², and ash pit a³, may be
of any usual or preferred kind, the present invention being intended for use with
any furnace, heater or other source of fuel combustion
The smoke consumer B is herein shown as located in the head at of the furnace,
or boiler, and is connected by a pipe b with the dome of the boiler or other source of
steam supply under pressure, à dip pipe 6 and cock 63 being provided in order
that dry steam may be had if required One or more smoke consumers as desired
can receive then steam supply from a supply pipe 6. provided with a supply valve b',
and preferably also each provided with a regulating valve b
The steam from the supply pipe 63 passes through the regulating valve b³ to
within a discharge chamber 68, in which is concentrically extended a discharge

page_text: nozzle b' which has an open end 68 terminating a considerable distance within the
discharge chamber, for a purpose presently to be explained.
At its outer end the dischaige chamber 6 is provided with an air box 69, shown
as laterally extended and provided on its inner walls with a plurality of interrupted
diaphragms on staggered partitions 610, the au having access to the au box at bi
Refering further to Fig 3, it will be seen that the discharge chamber 6 18
secured for convenience by a shouldered nut or union 6 to a nipple on the an
box, and that it has an extension 1, shown as telescopically mounted on its inner
or forward end at 61, this provision being a preferable one for the purpose of
enabling the apparatus to be accomodated to vaiying thicknesses of furnace walls
or to other conditions
At its forward end the discharge chamber cares an adjustable deflector 616,
flared at its horizontal sides as indicated at b, Fig. 3, and converging at its top and
bottom sides, as shown at 61, Figs 1 and 2
This deflector 18 adjustable angularly with relation to the discharge chamber,
in order that the steam and air may be properly commingled and directed at the
precise part of the fire box where it will be of the most seivice
As herein shown, this adjustment is attained by providing the discharge chamber
with curved upper and lower wings 619, receiving reversely curved flanges 20 on
the adjacent end of the deflector, one or both of these being slotted to receive
fastening bolts 2 for clamping the deflector in any adjustment
The aim in this device has been to provide means for producing more perfect
combustion than has been possible hitherto, and my correspondents have found
that by extending the discharge nozzle a considerable distance within the heated
portion of the discharge chamber, that the an and the super heated steam coming
together, as they necessarily do under such circumstances in an exceedingly hot
chamber, and then impinging against the top wall 618 of the deflector and being
directed by the adjustable deflector in the precise duection and portion of the fie
box where they will meet the products of combustion to the best advantage, develop
combustible gases to a remarkable extent and perfection
Also, my correspondents have found that by constructing the free end of the
discharge nozzle entirely open and preferably slightly flared, as shown at ³, there
18 a superior spraying effect, and the discharge nozzle is automatically maintained
open and clear of foreign clogging matter
This 18 of special advantage in a device of this kind, and it is found that it
materially enhances the free and uniform working of the smoke consumer
Leaving the discharge nozzle entirely open permits the discharge of the steam
without hindiance, so that it has no tendency to condense, and also it has a
superior force, the result being that when the commingled an and div steam
strike forcibly against the opposing wall of the deflector, a diy spray is driven out
over the fire in a most effectual manner
I wish also to lay especial emphasis upon the air box feature of this improved
smoke consuinei
As 18 well known by all who are practically conversant with these matters, the
noise of the injector type of smoke consumers 18 exceedingly objectionable; and
accordingly, the removal of this noise is of great advantage and value
By providing the interrupted passage way for the entrance of the air, as it is
sucked in by the steam blast this noise is stopped, and the apparatus works sub-
stantially noiselessly
By adjusting the regulator, the proportion and amount of steam and air may
be vaued as desired, and it is to be noted that the relations of the parts particularly
the location of the valve 65 are such that the steam is without interruption or
tendency to condense, so that a cutting down of the amount of steam does not
produce a wet steam, but leaves the diy steam blast the same as before, this is of
considerable advantage
Various changes in details of construction and combinations of parts may be
resorted to within the spirit and scope of the invention
