Y

The objectof the invention is to provide a fixed blower for.- this type -of boiler which is so positioned andv articulated that it may be readily inserted through and withdrawn A from the openings commonly, provided in the boiler setting and which is so construct- 'ed as to blow over part of the boiler and may be quickly and easily manipulated.

'An-"eyev Steam isi 'then turned*l on yby mulation" iof sootstherefroinf The section 11' is then blown from `the top,of the drum at this side of the wall by-a. like manipulation .of the nozzle.

In, a boiler setting where there are no clean out doors opposite the top of the mud drum as where there is a bank of boilers placed side by side, the tubes and the top of thedrum may be blown by means of a hang- 'ing nozzle, which is projected through openingsl and 17 inthe 'front and rear sides respectively of the wall above the top of the fire arch 'l8fcovering the fire chamber which opens into theforward side of the -boiler setting. team is supplied to this nozzle through a branch pipe 19 leading laterally from the supply pipe 6 and around to the forward side of the setting above the cpening. This supply pipe-19 leads into the lower'end of a casing 2O andleading laterally from this casing is a. short branch 21 having 'a swiveled connection with the cas# ing tofturnupon its longitudinal axis. A tube section 22 is 'connected to the short section 2l by an elbow and extends downward at right angles-thereto to swing upon the axis of the section 2l. At its ylower end vthe 'of steam at an angle.I turnedjto project the steam in `any. desired section 22 is bent laterally. and to this laterally bent end a tubular section 23 is attached by means of a swivel head 24-and extends parallel with the line of the section- 22. The extreme lower end of the section 23 is provided with'a'head 24 having an end wall 25 formed .with an opening. to receive a rotatable jet 'nozzle 26. The' wall 25 is;

formed at an angle to thelongitudinal axis of `the tube section so that' the nozzle` will set at'v an angle to the tube to project a jet The jet. nozzleis direction, by means of a rod 27 having a loose connection at itis lower' endl with the nozzle and in `extending upward through the tube' section 23 and outward. through. the

swivel head 24 which also forms an' elbow for connecting. the

sections

22 and 23. The outer end'ofthe rod'27isprovided .with a crank handle '28 by means of which the -ro'd is turned to .turn the jet nozzle. When not in use thetube section 22 is swungv upward turning upon the longitudinall axis'of the branch 2l, into the position shown .in dotted lines in Fig. l and the tube section 23 is permitted to hang. downward-alongside of the wall `where vit will be out of .the way.

rI his hanging nozzle is vbrought-into operative position by turning' the tubesection, 22

downward .to bring itsx'lower ,end opposite the 'opening 16 at the same time projecting l the 'section 23 4through the` opening and -downward between the rows of lboiler tubes. A brace or laterally extending arm 29 is adjustablysecured to the head 'or fitting 24 toV engage 'the lower. sid-e ofthe opening- 1 6 in the'wall-and hold the nozzle' in operative position. vWhen so insertedand the steam l turned o n,.every-part of the lower .ends ofl thebo'ii. r tubes at one side of the .wall Sand the top of the mud drum may be thoroughly cleaned by the jet-'of steam issuingthrough ,the jet nozzle 'which is turned by means of the handle 28 to direct the steam into every part of the lower end of the boiler setting. `The same construction of hanglng nozzle may be applied to the rear side of the boiler setting in a position to be projected through the opening 17 in order that the space at the rear side of the battle wall may be cleaned when .there are no openings at the rear side of the setting near the top of the drum.

. A- short vertical pipe 30 extends upward from the fitting 20 and is attached thereto by a suitable swivel' connection and a tubular section 3l-is connected thereto by an elbow and extends laterally therefrom. rllhis tubular section 3l ijs ofjsukiicient-length to extend t va point opposite either of two openings 32 in the wall of the boilersetting, said .openings being arranged .substantially onequart'er of the way around towardeach side from the'front centerline to the wall, The outer end of this tube 'section31-1s turned vupwardly and mounte' upon this upturned end` isa fitting 33carry ng an extension tube Set-'adapted to project throughthe opening V .in the wall. The inner end of the extension Sais 4provided witha `headr35 forming a jet nozzleto projectv steam across vthe boiler tubes opposite'saidopening. The-fitting 33 is so attached l,to the tube 3l that it may be turned freely thereon and thus the extension t tube 34 maybe swung from side toside within the opening or turned Rto' engagethe similar opening 'at the opposite side of the bring it opposite said opening.
