"IMPROVEMENTS IN THE MEANS AND APPARATUS FOR PURIFYING STEAM AND OTHER
BOILERS, FEED WATER HEATERS AND OTHER SIMILAR VESSELS AND PROMOTING
THE GENERATION OF STEAM THEREIN
"
This Invention has for its object improvements in the means and apparatus for
purifying steam and other boilers, feed water heaters and other similar vessels and
promoting the generation of steam therein and relates particularly to boilers for
generating steam but it is also applicable to feed water heaters and other boilers or
vessels when heat is employed for precipitating, extracting and collecting mud,
chemicals, and other extraneous substances from water and other liquids
The object of this invention is to cause a continuous movement of the water or
liquid by applying fire or heat to the boiler or other vessel and thus to force the
water or liquid upwards and through a tube or tubes into an inner vessel or
collector placed inside of the boiler or outer vessel, and by this ineans causing the
substances or matter to separate from the water or liquids and to precipitate
deposit and collect in the inner vessel
In order to accomplish this and carry my improvements into effect I fix suitable
vessels or collectors of various or any shape or form with one or more tube or
tubes having a cap or hood attached inside of the boiler or vessel and for the
purpose of cleaning I connect an ordinary cock or valve with pipes to the said
collector and to the outside of the boilers or vessels and blow out the said
substances or solid matter by the pressure of the steam in the said boilers. Or I
take the collectors out when the boilers or vessels are cold and clean them in tho
ordinary way
By the use and application of this invention it will collect all dirt, mud and
solid matter and prevent incrustation in boilers by precipitating the mud or dirt
when in the act of boiling into the collector and not allowing it to rest at any
time on the plates of the boiler or vessel, and it will also contribute very much
to the generating of steam by causing immense circulation of the water

"IMPROVEMENTS IN THE MEANS AND APPARATUS FOR PURIFYING STEAM AND OTHER
BOILERS, FEED-WATER HEATERS AND OTHER SIMILAR VESSELS AND PROMOTING
THE GENERATION OF STEAM [THEREIN]
This Invention has for its object Improvements in the means and apparatus for
purifying steam and other boilers, feed water heaters, and other similar vessels and
promoting the generation of steam therein and relates particularly to boilers for
generating steam but is also applicable to feed water heaters and other boilers or
vessels where heat is employed for precipitating extracting and collecting mud,
chemicals, and other extraneous substances from water and other liquids
The object of this invention is to cause a continuous movement of the water
or liquid by applying fire or heat to the boiler or other vessel and thus to force
the water or liquid upwards and through a tube or tubes into an inner vessel or
collector placed inside the boiler or other vessel and by this means cause the
extraneous substances or matters contained in the water or other liquid to separate
therefrom and to be precipitated, deposited and collected within such inner vessel
or collector
In order to accomplish this I fix one or more of such vessels or collectors of any
convenient form and fitted with one or more tube or tubes with a cup or hood
attached inside a boiler or other similar vessel
In order to enable such vessels or collectors to be cleansed when requisite I
connect an ordinary cock or valve and pipe to each collector and to the outside of
the boiler or other vessel wherein it is fitted and blow out the extraneous
substances collected therein by the pressure of the steam in the boiler-Or I
take out such collector from such boiler or vessel when cold and clean it in the
ordinary way
And in order that my said invention may be better understood and readily
carried into effect I will now proceed with the aid of the accompanying drawings
to more particularly describe the same
Figure 1 of such drawings represents a vertical section and Figure 2 a plan view
of my improved apparatus as applied to boilers or vessels for precipitating
extracting and collecting the impurities contained in the water or other liquid
Such apparatus may be made either of cast or wrought iron or steel copper or
brass, or any other suitable metal and either round oblong square or of any other
shape most convenient to allow of its being properly adjusted inside the boiler or
other vessel to which it is to be fitted-A is the collector B the tube-C the
dish or trap cover-and D the cup or hood-Such collecting apparatus may be
made complete in one casting or in separate parts and subsequently fitted together
as may be most convenient
The mode of application and the operation thereof is as follows-The collector
A is fitted inside the boiler or other vessel containing the water or liquid and so
adjusted as to be over and above any part or parts where the action of heat or
fire is applied, after which the water or other liquid is heated to a sufficient tem-
perature to cause the impurities and other foreign matters contained therein to be
precipitated
The tube B, causes a continuous circulation or movement of the water or other

page_text: liquid to take place and such liquid rushing in at the bottom of, ascends through
such tube until it comes in contact with the cup D and so causes the impurities
contained therein to be precipitated into the collector A wherein they are imme-
diately trapped by the dished cover C and kept quiescent thus not only effectually
preserving the boiler or other vessel from incrustation but greatly promoting the
generation of steam therein owing to the continuous violent agitation of the water
or other liquid already described
With respect to this application of my invention I would here remark that the
collector A can in some instances be used either with or without the dished
cover C and cup D
In order to cleanse my improved collecting and purifying apparatus I prefer
when requisite to remove it from the boiler or other vessel to which it is applied
and clean it in the ordinary manner
Figure 3 of the drawings shews a view partly in section and partly in side
elevation of a feed water heating apparatus constructed in accordance with my
invention for precipitating, extracting and collecting the impurities from the water
before it is forced into the boilers-Such improved apparatus is made partly of
wrought iron, cast iron, and brass or copper tubes either plain or corrugated and
may be either square oblong round or hexagon (but preferably with an oblong
base) and with heaters or collectors in one or more sections or parts as required to
heat the water and precipitate the impurities therein
A portion of these sections is heated with exhaust steam until the water or liquid
is brought to as high a temperature as possible while the remaining sections are
heated to as high a temperature as the water in the boilers by live steam
Figure 4 shews a plan view of such improved feed water heating apparatus In
these Figures A represents the inlet for the water-B the vertical pipe or passage
for the same-C the brass tube for the exhaust and live steam to pass through―
D the collector-E the exhauster-F the live steam inlet G the exhaust steam
outlet-H the condensed water from the live steam outlet-I the delivery pipe or
passage from one collector to another and K the delivery pipe or passage from the
water to the boiler
The mode of operation is as follows-The apparatus is fitted in any convenient
position between the feed pump and the boilers and consists of one or more separate
heaters and collectors heated by the combined action of the exhaust and live steam
or either Or by the application of heat from boiler or furnace flues or hot air or
by other suitable means- -The water being forced in at A passes up the inner
vessel or vertical pipo B and is heated by the exhaust and live steam or hot air
passing through the tubes C to a sufficient temperature to cause the deposition of
the impurities and other foreign matters contained therein-thence from pipe B the
water passes up against the underside of the chambers E' and F¹ which act as
hoods or caps to precipitate and carry the impurities contained in the water into
the collector D where they are collected and remain quiescent during the pumping
of the water and from whence they are subsequently blown out by the pressure of
the steam in the boiler through ordinary or other suitable Cocks or valves at D¹-
The water then passes from each heater through the pipe I until it finally passes
through the outlet pipe K into the boiler in a purified state
Having thus particularly described and ascertained the nature of my said
invention and the manner of carrying the same into effect I would have it under-
stood that what I claim as novel and of my invention is
Firstly The fitting a boiler or other similar vessel internally with a collecting
and purifying apparatus constructed and fitted substantially in the manner and for
the purposes herein before described and illustrated
Secondly-The improved construction of feed water heating apparatus sub-
stantially in the manner and for the purposes herein before described and
illustrated

page_text: Thirdly The promoting the increased generation of steam by means of a
continuous violent agitation of the water or other liquid induced and sustained
substantially in the manner hereinbefore described and shewn

seal this second day of March in the Year of Our Lord One thousand
eight hundred and eighty three
