This invention relates to a soot blower adapt
ed for use in cleaning ?uid heaters and the like.
The invention has as an object to provide a
soot blower of the above mentioned character
5 which will include a movable blower element, a
?uid pressure actuated driving mechanism for
moving the blower element, and an improved,
means for disposing of the ?uid discharged from
this mechanism.
The above and numerous other objects and
advantages of this invention will become more
apparent as the following description proceeds,
particularly when reference is had to the accom
panying drawing wherein:
,
Fig. l is a side elevational View partly in sec
tion of a soot blower constructed in accordance
with the teachings of this invention;
Fig. 2 is a View similar to Fig. 1, showing a
slightly modi?ed form of construction; and
20
ably secured to a supply pipe shown in Fig. 2
and designated by the reference character 32. A
an
valve, designated generally by the reference ,char- ’
acter 33 is disposed in the gooseneck adjacent the
lower end thereof, and controls the flow of clean
ing ?uid from the supply pipe to the goo'seneck
and thus to the blower element.
10
While the valve 33 may bev actuated in any
desired manner, it is preferably actuated in
timed relation to the rotation of the blower ele—
ment in accordance with the usual practice. For
this purpose there is provided a cam 36 ?xed for
rotation with the blower element and arranged
to actuate the stem 31 of a pilot valve 38. This
pilot valve may be in the nature of a three-way
valve of standard construction being suitably
Fig. 3 is a view similar to Fig. 1 showing a still
connected to a source of ?uid under pressure 20
and an exhaust. The arrangement is such that
when the valve stem 3'! is depressed by the cam
36, the valve 38 is actuated to admit ?uid under
pressure above piston 39 in cylinder 40. This
depresses the piston 39 and causes the stem Ill
thereof which is secured to the main. valve to 25
QO ment under pressure.
In general, it is the custom to mount these
blower pipes for movement so that the jets of
cleaning ?uid discharged therefrom may be di
rected adjacent different portions of the ?uid
heater to be cleaned. The present invention is
directed more particularly to a construction in
which a ?uid actuated motor, of any desired
character, is arranged to move the blower ele
ment and in which provision is made to conduct
the ?uid discharged from the ?uid motor through
the ?uid heater wall for discharge into the in
terior of the ?uid heater.
Referring then particularly to the drawing,
in 5
the ?uid heater the blower element has its end
suitably journalled in one end of _a gooseneck
‘ilk, the other end of this gooseneck being suit
further modi?ed form of construction.
In the cleaning of ?uid heaters such as boilers
and the like it is customary to provide a blower
element or pipe having discharge openings or noz~
zles through which a cleaning ?uid supplied to
the pipe may be discharged adjacent the por
tions of the ?uid heater to be cleaned. The clean
ing ?uid used may be steam, air, or any other
similar ?uid which is supplied to the blower ele
M)

(Cl. 122-4592)
wherein like reference characters designate cor
responding parts throughout all views, the nu
meral 25 designates a blower element which pro
jects through an opening 26 in the wall 21 of a
?uid heater (not shown). In accordance with
the usual practice, a wall box 28k is preferably
mounted in the opening 26, the blower element
passing through the opening in the wall box as
illustrated.
It will be understood that the blower element
25 is adapted to be supplied with cleaning ?uid
and that the portion of the blower element which
projects into the ?uid heater is provided with
a plurality of discharge nozzles (not shown) for
discharging cleaning ?uid adjacent the portions
60 of the ?uid heater to be cleaned. Exteriorly of
open the latter thus admitting cleaning ?uid
from the supply pipe to the 'gooseneck. It will
be understood that the cam 36 is provided with
a cut out portion so that during a portion of the
rotation of the blower element the valve 33 is
permitted to close.
.
For the purpose‘of rotating the blower ele
ment 25, there is provided a suitable ?uid act-u»
ated motor which may be of any desired char~
acter. Since the structure of this ?uid motor
forms no part of the present invention, only the
housing 240k which encloses the motor is illus
trated in the drawing, it being understood that
the motor is suitably connected to the blower ele 40
ment in any desired manner to rotate the same.
Fluid under pressure for rotating the mot-or is
supplied to the same from any suitable source
by a conduit 245k, While the ?uid exhausted from
the motor is con-ducted away from the housing
2M)k by a conduit 2411*. The housing 240k is
suitably secured to the wall box 28k as by the
bolts 5t, while ‘the interior of the housing is pro~
vided with suitable ?uid intake and exhaust pas~
sages (not shown), which communicate with the
?uid supply and exhaust passages 246k and 241k
respectively.
'
As illustrated the wall box 28k is provided with
an enlarged portion 210, and a passage 21! is
formed in this portion. One end of the passage
2H is placed in communication with the pipe
2411* while the other end of this passage is ar
ranged to discharge into the space between the
wall box and the blower element. Thus the ex
haust from the ?uid motor will be conducted
2,110,532
2
directly to the wall box and thus through the
boiler setting.
In this embodiment of the invention means is
provided for indicating whether or not cleaning
?uid is being supplied to the blower element. For
this purpose a cylinder 215 is placed in com
munication with the gooseneck 3N‘ by a pipe 216.
A piston 21‘! located within the cylinder is nor
mally held in its lowermost position by a spring
10 218. When, however, cleaning ?uid under pres
sure is admitted to the gooseneck, this ?uid acts
through connection 216 to force the piston 21'!
upwardly against the force exerted by spring 218.
Secured to the piston 21‘! is a stem 2'l9 arranged
15 to close a switch 280, this switch being normally
held open by a spring 281. This switch controls
the energization of a suitable alarm 282 which
may be a light, bell, or the like.
It will be apparent that whenever cleaning ?uid
20 under pressure is supplied to the gooseneck, the
piston 21'! will be moved to close switch 28!} and
thus energize signal 282. Thus, by reference to
this signal, the operator may be advised whether
or not cleaning ?uid is being supplied to the
25 blower element.
In Fig. 2 there is disclosed a construction quite
similar to that disclosed in Fig. 1 in that the ?uid
motor is housed in a casing 240*“ suitably secured
to the wall box 28*“. Fluid under pressure is sup
30 plied to the ?uid motor by way of a supply pipe
246m, the supply pipe being tapped into the side
of the casing.
In this embodiment of the invention the ex
haust from the ?uid motor is conducted to the
35 wall box by a passage 285 cast in the housing
240m. Obviously, the exhausting fluid will ?ow
through the passage 285 and into the space be
tween the inner surface of the wall box and the
outer surface of the blower element, the exhaust
?uid ?owing through the wall box to the combus
tion chamber.
Fig. 3 shows a still further means of disposing
of the exhaust from the ?uid motor. By refer
ence to this ?gure it will be noted that a passage
285n is cast in the casing 240". In this embodi—
ment, however, the passage 285“, instead of‘ dis
through said wall box and so connected to said
?uid motor as to be driven thereby, of means in
cluding a passage formed in the casing of said
?uid motor in communication with the wall box
for conducting the discharge from the ?uid motor
to the said wall box.
2. In a ?uid heater cleaner, the combination
with a wall box mounted in the ?uid heater set
ting, a blower element projectingthrough said
wall box, and a ?uid motor located exteriorly of 10
said setting and connected to said blower ele~
ment for driving the same, of means providing a
passage extending longitudinally of said wall box
through one side thereof, and means for con
ducting to the said passage the exhaust from‘
the ?uid motor.
3. In a ?uid heater cleaner, the combination
with a wall box mounted. in the ?uid heater set
ting, a blower element, a passage in said wall box
through which the blower element projects from 20
the exterior to the interior of the fluid heater set
ting, a ?uid motor located exteriorly of the set
ting and connected to the blower element to drive
the element, a casing enclosing the ?uid motor, a
second passage formed in the wall box, and a 25
connection between said last named passage and
the casing to' provide for the conduction of ex
haust from the ?uid motor to the wall box.
4. In a ?uid heater cleaner, the combination
with a wall box mounted in the ?uid heater set
ting, a blower element projecting through said
wall box, and a ?uid motor located exteriorly of
said setting and connected to said blower ele
ment for driving the same, of means providing a
passage extending longitudinally of said wall box
through one side thereof, and means providing a
passage in the casing of said ?uid motor, said
last mentioned passage communicating with the
passage in said wall box for conducting the dis
charge from the ?uid motor to the passage
through the wall box.
5. In a ?uidheater cleaner, the combination
with a ?uid heater wall, a wall box mounted in
the ?uid heater wall and providing a passage
through the wall, a blower element projecting
beyond said wall box, and a ?uid motor located
charging directly into the wall box, discharges
exteriorly of the ?uid heater wall and connected
into a passage 28-‘6 formed in one side of the wall
to the blower element for driving the same, of
a casing for said ?uid motor secured directly to
box. It will be understood that the passage 285
extends entirely through the boiler wall 2‘!n so
that the discharged ?uid will be conducted to
the combustion chamber.
From the above it will be apparent that the
invention provides a movable blower element, a
?uid actuated mechanism for moving this blower
element, and means for conducting the ?uid dis~
charged from this ?uid actuated mechanism to
the interior of the fluid heater. Thus the ?uid
discharged from the ?uid motor is effectively
60 disposed of and is prevented from exhausting into
the room in which the ?uid heater is located.
While several embodiments of the invention
have been described with some detail, it is to be
understood that the description is for the pur
65 poses of illustration only and is not de?nitive of
the limits of the inventive idea. The right is
reserved to make such changes in the details of
construction and arrangement of parts as will fall
within the purview of the attached claims.
What we claim as our invention is:
1. In a ?uid‘heater cleaner, the combination
with a ?uid motor located exteriorly of the ?uid
heater setting, a wall box mounted in the ?uid
heater setting, and a blower element projecting
the wall box and closing the outer end thereof, I
means providing an exhaust passage for the ?uid
motor in the casing, and a connection between
the exhaust passage and the passage provided by
the wall box whereby the exhaust from said ?uid
motor is conducted through the ?uid heater wall. K
6. In a ?uid heater cleaner, the combination
with a ?uid heater wall, a wall box mounted in
the ?uid heater wall and providing a passage
through the wall, a blower element projecting

casing for said ?uid motor connected directly to
the wall box and closing the outer end thereof,
and means providing an exhaust passage for the
?uid motor in the casing, said exhaust passage
communicating directly with the passage through
the wall box whereby the exhaust from the fluid
motor is conducted through the ?uid heaterwall.
