, To all lwhom it may coment:

Be it known that I, Gennari* BUnGnss,.a citizen of the United States of America, residing at Detroit, in the county of Wayne -and State of Michigan, have invented certain new and useful Improvements in Boiler-Tube Cleaners, of which the' `follow- Ving is a specification, reference being .had

therein tothe accompanying drawings.

This invention relates to tube cleaners for boilers, and more particularly to soot cleaners yespecially adaptedfor use in cleaning the tubes or flues of verticalboilers.

The primary object ofjny invention is to provide positive and reliable means, in a manner as hereinafter set forth, for expeditiouslysubjecting the 'tubes or ilues to the .action of steam or other luid,under pressure, whereby soot, ashes and incrustations are removed from the walls of the lues.

Another object of this invention is not only toremove soot, incrustations, and foreign matter frorn the tubes or fluesA of a boiler, but to enable the work to be done While the boiler is steaming or in use and withbut the necessity ofl opening any portion of the boiler settings, which openingr would allow of the escape of heat and cool off the boiler.

A further object of this invention is to provide a cleaner embodying a reciprocal `Huid distributing member adapted tto be placed in an operative position by uid adnait .ed to the cleaner, andretracted by fluid after a cleaning operation.

A still further object of this invention is to-provide a simple, durable and inexpensive cleaner that can be advantageously used in connection with a vertical tube boiler, .particularly of the Wickes type.

The above and other objects are attained by a mechanical. construction that will be hereinafter; specifically described and vthen claimed, .and reference will now be had to the drawing wherein Figure 1 is a longitudinal. sectional view of the preferred form of cleaner, ,partly broken away; Fig. 2 is a side elevation of a ,modified form of cleaner, partly broken .away and partly in section; Fig. 3 isa crosssectional view taken on the line III-I-JIF-of Fig. 1; Fig. 4 is a similar view taken on the line IVI V of Fig. 1; Fi 5 isa similar view taken on the line V of Fig. 2;'and

tionfnipple'a and a cap 5. The reduction nipple 4 has a short connection 6 with a T 7, which is connected to a steam supply ipe 8 provided with a controlling valve 9. he T alsoV constitutes a drain for the .tubular body or cylinder 1.

'I he cap 5 haseJ concentric opening 10 and rec1procal in said opening is a. perforated or apertured fluid distributing ipe or member 11. This member is arranged) longitudinally of the body or cylinder 1 and the outer end e ends 'thereof exteriorly screw-V DUBOIS, PENNSYLVANI, -AUDBPOBATION 4('JI thereof is closed as by a cap 12. VTheinner end of the member-11 is connected to a hollowpiston head 13 provided with packing rings 14. Within the hollow piston 13 is a valve seat 15 ffora valve 16, said valve having the stem 17 extending through a spider,

18 within the hollow piston. The end of the valve stem 17 'has a head 19 and encirclin said valve stem, between the head. 19 and the spider 18" is a coiled compression spring 20 that holds the valve 16 normally seated. In the body or cylinder 1, adjacent the cap 5, is a coiled spring 21 that encircles the member 11 and cushions a reciprocal movement of the member 11 when impinged by the piston 13. The cap 'has a connection-22 with a steam or other fluid supply pipe 23 and said pipe is provided with an ordinary valve 24 for controlling the admission of steam to the body or cylinder 1.

ln Figs. 2 and 5 of the drawings, there is 7 illustrated a slight modification of the inven tion, wherein the cleaner body orfcylinder 1 has a longitudinal enlargement 25 provided with a by-pass 26 serving functionally the same purpose asthe steam supply pipe v23 i and the connection 22.

and iiues 29. The cleaners are mounted in the boiler settinbeing sopom los a cleaner body or cylinder the piston isy moved toward the inner end of the cleaner body or cylinder, thereby projecting vthe fluid-distributing member 11. Simultaneous with this operation the steam or other .Huid

underpressure, unseatsthe valve 16 and the fluid is admitted through the passage in the` piston' to the member 11 and discharged through the perf'orations or apertures thereof'ainong the tubes of the boiler. The inward movement of the member 11 is cushioned by the spring 21 and after the flues 29 of the boiler have been blown and thoroughly cleaned, the supply 'of steam to the cleaner body oi' cylinder l is shut ofi' and the supply admitted to 'the inner end of the body orcylinderilthrough the medium of the pipe rllhe fluid under pressure then retracts the fluid ydistributing -niember 11 and restores thejsaine to normal position, the steam entrapped inback of the piston 7 when the valvewvas closed'cudiioning the piston in its return movement. 'f

v The uid distributing member of e'ach cleaner being withdrawn from the heat zone of the fire chamber and housed within 'the body or cylinder when not in use and in no wise subjected to the heat'in-fthis position is consequently fully protected from burning out, and the cleanerv or cleaners being fined in the boilersetting are ready for use at any timedesired, and require yno shutting down' of the boilerfor operation. v The distributing* pipe ybeing perforated on all sides, projects the cleaning fluid radially of the pipe in alldirections to effect a thorough cleansing of all the tubes. i,

The preferred embodiments have been illustrated, but it is to' be understood that the structural elements are susceptible to such modifications yand' variations as fall within the scope of` thek appended claims. f `that I-'claimiissl. 1`. ln a cleaner` for boilers,y a cylinder, a
