ROBERT E. JACKSON AND EDIIVIN M. JENKINS,-OF PRINCETON, WEST VIRGINIA..

FLUE BLOWER.

Application led November 16, 1921. Serial No. 515,619.

To all 'whom t may concern.' v Be it known that we, ,ROBERT E; JACKSON and 3DWIN M. JENKINS, citizens of the United States, residingat Princeton, in the county of Mercer and State of West Virginia, have invented certain new and useful Improvements in Flue Blowers, of which the i'ollowing is a specication. l

This invention'relates to improvements in flue blowers and more particularly to a de# Yvice, adapted to be attached to a boiler whereby any selected flue may be cleaned as desired.

In a prior Patent No. 1,416,209, granted May 16, 1922, we have disclosed andclainied a iiue blower in which a rotatable support is arranged within the lire box and a flue cleaning device is transversely mounted on said support and adapted to'be alined with the end of the liue to be cleaned. In the present invention, we have provided a flue cleaner in which movable parts within the boiler are eliminated. A plurality of headers are arranged transversely of the smoke box mounted on suitable supports, a header being provided for each vhorizontal row of tlues. The headers are provided with a plurality of lead lines or pipes arranged therein communicating with the individual liues of the row. Each of the headers is connected to a suitable supply of compressed air, steam, or other compressed fluid and means are provided for feeding the fluid to any selected pipe within' the header.

`The valve mechanism whereby any desired connecting pipe is connected to the sourceof supply is arranged on the outside of the boiler and is readily accessib-le at all times.

In the accompanying drawings, We vhave shown one embodiment of the invention. In this showing:

Figure 1 is alongitudinal sectional View of a portion of a boiler showing the invention applied,

Figure 2 is a transverse vertical sectional view on line 2-2 of Figure 1,

Figure 3 is ay side elevation of a portion ofV the'boiler showing the valve arrangement, A

Figure 4 is a detail view of a portion ot the header,

Figure l5- is an end elevation thereof,v Figure 6 is a detail view of the header valve casing, parts being shown in xsection, Figure 7 is a plan View ofone ot the headers, f

'Figure y8 is a sectional view on line 8 8 of Figure 6 and, Figure 9 is a detail viewfof the inner end ot one of the connecting pipes.

Referring to the drawings, .the'reterence numeral designates the smoke box ot a boiler and 2 the front flue sheet. Theboiler disclosed 1s the locomotive type', but the in'- `vention may be employed with any ltype of lire tube boiler. A plurality ot' lues 3 eX- tend Vthrough the flue sheet in the usual manner. p

'Ilie'lu'e blower forming the subject matterotv the invention consists of a plurality of headers 4l arrz-ulged transversely` oil the smoke box and in horizontalalinement with each row or" lines. One end of the header is provided with grooves 5 for ythe reception oj brackets 6 secured to the wall ot the boiler. The opposite end of theheader eX- tends through an opening inthe opposite side of the boiler and` is supported byA means oi' suitable brackets. Asv shown, ths ,end of the header is enlarged, as at 7, the body portion and the enlargement being provided with flanges 8 adapted to receive boltsQ by ineansot vwhich the sections are held tothe stem is square, asat18. A plate 19 is arranged on the valve casing, the platebeing provided with a circular opening for'the passageA of the circular portion 17 of the valve stein. This` plate is provided witha plurality of notches 20, arranged about its periphery. A' handle 21 is arranged on the squared portion ofthe valve stem and retained in position by means ot' a pin 22. The handle extends beyond the plate 19 and is provided with a plunger 23 arranged in a recess and normally retained in position by means of a spring 24.

A plurality or connecting pipes 25- are arranged within the header, the number of connecting pipes in each header corresponding to the number of llues in the horizontal row. The ends of these pipes within the enlarged portion 7 are arranged concentrically in alinement with the opening 14 in the valve. The connecting pipes 25 extend longitudinally of the header to a point in alinement with the l'lues to which they are to be connected and are then olset, as at 26, and extend through the front of the header. The pipes or passages 25 are provided with lead pipes 27 extending into the end of the tlues (see Figure l). These lead pipes are provided with flared ends 28, the flared portion extending downwardly to direct the blast of steam or air against the lower wall othe Hue and insure perfect distribution ot' the. cleaning fluid within the tlue.

The operation of the device is as follows:

When a tine is to be cleaned, the valve is turned to connect the valve casing with the proper pipe or passage 25. Steam, compressed air or other suitable fluid is introduced into the valve casing through a pipe 29 which may be provided with a suitable valve (not shown) whereby the supply of fluid to the valve casing may be controlled. The position of the opening in the disk valve 13 may be determined by suitable indicia arranged on the plate 19 and disposed adjacent the notches 20. The plate will be provided with one more notch than the number of flues in each row, and one position of the handle 21 will indicate that the valve opening 14 is out of alinement with the pipes or passages 25, the other positions indicating that the valve opening is in alinement with one of the passages to direct fluid to a. given flue. The iuid passing through the opening in the valve and the pipe or passage 25 is directed to the lead pipe 27 thence to the interior of the flue.

lt is to be understood that the form of our invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described our invention, we claim:

1. A flue blower adapted to be arranged transversely of a boiler in alinement with a row of tlues, and being provided with a. plurality of passages corresponding in number to the number of flues, means for connecting said passages to the endsof the liues, a pipe connected to a source oit' compressed tluid, and means for connecting any one of said passages to said pipe.
