Automatic Boiler Cleaning Apparatus.
We, SPENCER ROBERT UDELL and HENRY BOEHMER, both living at 71, S. Water
Street, City of Chicago, United States of America, do hereby declare the nature
of this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement:-
Our invention has relation to an automatic boiler cleaning apparatus.
Our object is to provide a device of this character, which will overcome the ob-
jectionable features of the boiler cleaners now in existence, and at the same time
be durable and efficient in use.
Referring to the drawings forming a portion of our specification
Figure 1 is a side elevation of our device showing the mauner of its connection
to the boiler.
Figure 2 is a sectional elevation of the boiler cleaner proper, and
Figure 3 is a sectional elevation of a modification thereof.
In the drawings 1 indicates a boiler, constructed in the usual manner. Tapped
into the boiler at 2 is a water pipe 3, provided at one extremity with a skimmer 4,
having upturned ends as at 5. A pipe 6 connects the water pipe 3 to one of the
precipitating cylinders 7 of the cleaning apparatus, which will now be described.
Generally speaking, the boiler cleaner consists of two or more precipitating
cylinders 7 and 8, each provided with an upper head 9 and 9" and a lower head 10
and 10° appropriately secured thereto.
l'assing through the head 9 of cylinder 7 is a water pipe 11, whose discharge
end 12 is so arranged with reference to a deflector 13, secured to the lower end of
the pipe 11, that water issuing from the pipe is spread over the surface thereof,
for a purpose to be hereinafter set out. It will be observed that in Figure 2 we
have shown this deflector 13 as being of the general contour of a double cone,
while in Figure 3 we have shown it to be conical in shape, the apex of the angle
being near the point of discharge from the water pipe. We desire it to be under-
stood however, that the general outline and contour of the deflector may be
changed at will without in the least departing from the spirit of our invention.
A hood 14 is so arranged on the pipe 11 that it may, by means of a collar and
the bolt 15 be adjusted in any desired position thereon. It will be observed that
the adjustable hood is so disposed that it surrounds the deflector in such a manner
as to leave a space between it and the deflector, as well as between the inner sur-
face of the cylinder, and the outer side of the hood.
The cylinder head 9 is connected by means of a pipe or passage way 16 to the
head 9 of the precipitating cylinder 8. A suitable water pipe 17 provided with
a cock 18, leads to the lower part of the boiler. Attached to that end of the pipe
in the cylinder 8, is an adjustable hood 14 and deflector or guide 13 similar to
those heretofore described in connection with precipitating cylinder 7, but whose
effect as will hereafter appear, is the reverse of the one formerly alluded to.
The cylinders 7 and 8 are suitably connected at their lower ends to mud drums 19
and 20, each of which is provided with a blow off valve 21 and 22 of any well
known construction.

page_text: In the modification shown in Figure 3, we have provided a cone shaped deflec-
tor 23 in the precipitating cylinders 7 and 8, as is apparent, while the adjustable
hoods 29 and 29" are provided with decidedly sloping sides 24, a conical deflector 25
and 25% being arranged at the bottom of the pipe 11 and 17, as will be apparent
by reference to the drawings.
The operation of the device is as follows:-
The mud and scale" making material in the water of the boiler passes with
some of the water into the skimmer and through the pipe 6 to the precipitating
cylinder 7, by means of pipe 11, where it is spread over the deflector 13, passing
through the space between the deflector and the hood 14, when a portion of the
mud and other heavy materials is precipitated from the deflector and falls to the
bottom of the precipitating cylinder, and thence to the mud drum 19.
The water thus relieved of a portion of its material passes upward, between the
hood and the cylinder as shown by the arrows and out through the cylinder head 9
and by means of the passage 16, into the cylinder 8, through the opening in the
cylinder head 9, when it is again spread this time over the outer surface of the
hood 14 in the cylinder E. The water then passes downward between the hood
and the cylinder and is then relieved of the remaining portion of heavy material,
which falls to the bottom of the cylinder and thence to the mud drum. The water
then passes upward between the hood and the deflector and guided by the deflec-
tor 13, goes into the pipe 17 and is then conveyed to the boiler.
The mud and precipitates deposited in the drums are blown off when necessary.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what'
we claim is:-
-
1. A boiler cleaner, comprising precipitating cylinders, mud drums connected
therewith, a pipe arranged in one of the cylinders adapted to discharge water
over a deflector, a hood in said cylinder, means for conveying water from one cylin-
der to the other and discharging it therein, and means comprising a hood and a
deflector in the second cylinder, for directing the water to the boiler.
2. A boiler cleaner comprising precipitating cylinders, mud drums connected
therewith, a pipe arranged in one of the cylinders, adapted to discharge water over
an adjustable deflector, an adjustable hood in said cylinder, means for conveying
water from one cylinder to the other and discharging it therein, and means com-
prising an adjustable hood and an adjustable deflector in the said second cylinder,
for directing water to the boiler.
3. A boiler cleaner comprising precipitating cylinders, a pipe provided with
means for collecting water and material from the water in the boiler and adapted
to pass it into one precipitating cylinder, a deflector in the cylinder, beneath the
pipe, a hood over said deflector means for conveying water from one cylinder to
the other, and discharging it therein, a deflector in the paths of the said discharging
water in the said last named cylinder, means for directing the water from the
last named cylinder, to the boiler and mud drums connected to each cylinder for
the purpose of collecting the precipitated material. *
3 %.
4. A boiler cleaner comprising precipitating cylinders, heads on said cylinders,
a pipe provided with a skimmer located in the boiler and passing through said
head into the precipitating cylinder, a deflector at the bottom of said pipe, an ad-
justable hood, arranged over and around' said deflector, a passage from one cylin-
der head to the other a deflector located in the second cylinder and provided with
a surrounding hood, a pipe above said deflector for conveying water to the boiler,
and mud drums connected with cylinder for the purpose of collecting the precipi-
tated material.

cipitated material, and provided with blow off valves for the purpose of emptying
them.
6. A boiler cleaner comprising precipitating cylinders, means for admitting

rounding said deflectors, a passage from one cylinder to the other, and means for
conveying water from the last named precipitating cylinder to the boiler.
