Howse and Frank Bowers, Detroit, Mich., assignors to Diamond Power Specialty Corporation, Detroit, Mich, a corporation of Michigan Application December 27, 1932, Serial No. 649,104 ' - I Renewed October 18, 1937 6 Claims. 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.
