This inventionk relates V:to .boiler cleaners and refers more .particularlyto boiler'cleaners lofthe generaltype .in which the blower pipe is provided with aiplurality ofnozzles '4* distributed lthroughouty 1 its 1 longitudmal length` and through, which steam or other cleaning fluid is discharged against thehoiler tubesor other surfaces to be cleaned.

This `blowa` er, pipe lprojects through Ya wall hoX A23 mounted in the boiler wall 24 andv'its inner end vis Vsupported `by vsuitablebrackets frorn`k the boiler tubes 22. l' Y Turning movement; toA the pipe -20 is parted by means of a sheave wheel 25 yoverV which extends a chain 26 so that asthechain 26 is pulled, it will rotate the blower `pipe 20v and direct the ets from the nozzles 2l against differentportions of the boiler tubes. Steam, toA the pipe is furnished through the inlet 27k which opens into the Ablower head 28. f
1Within a casing or housing 28 ofthis, head iso-located a'sleeve29having a port 30 cooperatingwiththe portBl in the'slee've orL pipe extension 32. LIt will be noted that this i pipe extension v32 as well as the blower pipe 20 arescrew-threaded into thesheave wheel so that ineifec't theport Blis formedin2 a valve member that is in Xed relation to the blower. pipe. Therefore, `as the latter is A rotated the port 3l will. register with the port 30 so'that at certain predetermined rotative positions ofthe blower pipe 20 it will be open to'steam or like supply through the ports 30 andl `and head28and inlet 27 ,while at other positionsV the supply of steamzor thelile t?L the blower lpipe 20 is; automatically` cut o f Owingrtolthewarpingm'ovementof the y blower pipel 2() due to difference in expansion Vand to various other causesfthe construction as so ,fardescribedv would beV inoperative for any vpracticalv purposes vsincethe valvefmemo ber 32 would bindiin the sleeve 29,?butin the present novel, construction, this difficulty is overcome in lthe following manner. Y The. Y sleeve 29 at its inner end has a spheriealhead 33 with seats on a sphericalbearing ,blocky 34 ony which; it rocks to take Vcare of any rocking movement.` 'The bearing block 34 iskk itself slidably mounted to takecare of any vertical or lateral movement between the blower pipe 20 and the head 28, which latter is secured by bolts 36 or the like to the wall box 23. At `its outer end there is provided an end thrust bearing 37 and a steam tight connection is made by employing a corrugated type of flexible joint such as is produced by the corrugated lexible member 38. It will thus be seen that by the novel construction andl mounting of the valve member and its supports it is possible to form the movable valve member 32 rigid with the blower pipe 20.
In the modification shown in Figure 2, the blower pipe 20 is continued out to form the movable valve member 46 and this valve member'46 is mounted ina sleeve 47 which sleeve Y is connected at each end to 'the `blo-wer head 28a by means of corrugated flexible members or diaphragms 49. An end thrust bearingO is provided, whichbearing is formed in a slidable seat v51, so that in this construction as well as in that shown in Fig. 1, movement in every'direction is provided for.
' In Figure 3 is shown a still further modifi-- cation including a blower head 28?) and assolciated therewithisa'conical valve head 57 seating in a conical valve seat 58 formed in the'header or ygoose-neck 59. This conical valve 57 is rigidly connected to the `blower pipe 20'but thelatter itself `is formed in two parts connected by a ilexible diaphragm 60.
By this arrangement any deflection of the' blower pipe 2 as by the warping of the boiler tubes 61 on which the blower pipe is mounted 'by brackets62, is prevented from.
c bein transmitted to the movable valve member 5 Vbecause of thefflexibility in the blower pipe itself.
In Figure 4, 28o-represents the blower head, the general 'arrangement of the valve 57 and -the conical valve seat 58 in the goose-neck 59- being similar to that shown in Figure 3. The blower pipe 20 in thisr case is formed of two separate sections which are connected together by adriving lug 63 which has sufficient cleari ance to permit of some play. Vertical or .lat-
eral movement is taken care of by a thrust bearing 64 while any rockingmovement is taken care of by a spherical bearing 65' mounted in a. seat 66 which is itself slidingly mounted-to take care of 'vertical or lateral movement.
A still/further modification is shown inv Fi re 5 in whichfthe blower pipe20 is provi ed with a telescopic arrangement in the form of a slip joint 82totak'e care of any longitudinal `movement of the blower pipe 20 with relation to the stationary blower-head 83. f* The valve 84 is mounted in a seat 85 yinV the stationary head 83 and any rocking move-` ment is taken care of by the sphericalbearing 86 mounted ontheblower'pi'pe 20 and seating on the spherical bearing seat 86a.y The sheave wheel 90 may be mounted rigidly on the valve part 84, while the sleeve`82 maybe keyed tothe end 20a of the blower pipe `20 as by a key 91. The blower pipe 20 is rotatably supported from the boiler tubes 22 by means of bearings 87 and longitudinal movement of the blower pipe 20 1s substantially prevented by collars 88 on opposite. sides of the bearing portion 89.
I do not, however, desire to limit the invention to the particular constructions shown, since various changes and further modifications will be apparent from a disclosure of they particular `constructions described.
