BOILER-CLEANER.

Specification of Letters Patent.

Patented May 28, 1912.

Application filed November 11, 1911. Serial No. 659,797.

To all whom it may concern:

Be it known that I, LEO JOHN BAYER; citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Boiler-Cleaners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in boiler cleaners; and it consists in the novel features of construction more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure 1 is a side elevation of a water-tube boiler showing my invention applied thereto, part of the furnace wall being broken away; Fig. 2 is a vertical cross-section through the side wall of the furnace taken on the line 2-2 of Fig. 1; Fig. 3 is a similar sectional view enlarged, of the upper portion of the illustration in Fig. 2; Fig. 4 is a combined section and front elevation of the upper portion of the hollow sectional standard through which the steam nozzles operate; Fig. 5 is a side view of Fig. 4; Fig. 6 is a top plan of said hollow standard; Fig. 7 is an enlarged hori zontal section through the side wall of the furnace on the broken line 77 of Fig. 1; Fig. 8 is a front end view of the boiler showing the header nozzles in position; Fig. 9 is a perspective (broken away) of the nozzle installation for the header, detached; Fig. 10 is a longitudinal sectional detail showing one of the side nozzles closed by a perforated plug for projecting jets to assist the draft; Fig. 11 is a cross-section on the line 1111 of Fig. 10; Fig. 12 is a front sectional elevation of a modified form of nozzle-supporting standard; and Fig. 13 is a side elevation of the same.

The object of my invention is to provide a cleaner or soot-blower for water-tube boilers having the combined characteristics of the Heine and Babcock & Wilcox type, that is to say, boilers having a shell and a water-tube section in which the latter is battled transversely, and wherein either or both water-legs (or headers) are provided with hollow stay-bolts opposite the spaces between the tubes. This type of boiler (the EdgeMoor being an example) requires the installation of a blower system partaking of features identified with systems of both the Heine and Babcock & WVilcox boilers, said features being so disposed as to work cooperatively to accomplish the object in view, that is to say to not only dislodge the soot, dirt, ashes and other accumulations on the water-tubes (and shell) but to carry the material so dislodged out of the boiler-furnace in the general direction of the draft of the boiler.

A further object is to provide means for manipulating the movable nozzles by which the transverse projection of the cleaning fluid (steam) is accomplished, such means being particularly adapted to work in conjunction with the nozzle supports as at present installed in this class of boilers.

A further object is to provide other structural features the advantages of which will be fully apparent from a detailed descriptionof the invention which is as follows Referring to the drawings and for the present to Figs. 1 to 9 inclusive, F represents the furnace (the walls being broken away in parts) of a well known type of water-tube boiler (Edge-Moor), S representing the shell of the boiler, and T the water-tubes. As well understood in the art the water-tube portion is divided off into independent intercommunicating sections by transversely disposed battle-plates a traversed by the tubes, the general draft being rearward and upward from the fire-box F. In the present example two such battle-plates and three sections are shown though such number may 'vary in practice. Disposed along one of the side walls of the furnace opposite the middle section (in the present example) is a vertical opening 0 tapering inwardly (Fig. 7) there being located at the line of convergence of the vertical tapering side walls of said opening, a hollow standard or tube 1 provided with series of off-sets or shoulders 8. Between each pair of offsets'is confined a hollow rotatable cylinder 2 which is free to rock about the axis of the tube 1, there being one such cylinder opposite a space between two superposed series of tubes T. To insert the cylinders (or bearings) 2 into the tube 1, the latter must necessarily be made of (at least) two sections separable along a vertical plane, the upper and lower ends of the respective sections having cast with them the anchors or shoes 3 set in the brick work of the fursection adjacent such leg and a set of nozzles 4 installed as quite obvious, as otherwise no means would be present to blow this section. To assist the draft in such section it is clear that the uppermost nozzle 4 of the series would be provided with a plug 11 in which the passages 1 would be turned up so as to carry the products over the first bafiie a.

The arrangement of the hollow standard 1 with its series of bearings 2 is not the only method of supporting the nozzles 4 leading from the movable riser 5; and in Figs. 12 and 13 I show a modification in the form of an outer tubular standard 1 of uniform cross-section provided with an inner tube 2 through which the nozzles may pass. In that case as in the first form the member 1 is provided with transverse slots m for the free play of the nozzles, the pipe 2 being previously inserted into the tube 1. In this modification the member 1 need not be made sectional. Like the first form the standard 1 is provided with anchor arms or shoes 3 by which it may be secured to the furnace wall.

The operation, readily understood from the foregoing may be summarized as fol lows :To clean or blow the boiler the operator opens the necessary valves V whereupon the nozzles 8 will project the "steam jets in the spaces between the tubes in a general direction parallel with the tubes, the nozzles 4 on the other hand projecting the jets between the tubes but in a general direction transverse or at an angle to the tubes. To reach every available portion of the boiler section dependent on the noz zles 4, the operator seizes and moves the handle or lever 6, thereby causing the riser 5 to sweep about the common axis of the nozzles 4, the latter oscillating about the axis of the hollow standard 1. As stated above, any section of the boiler may be cleaned independently of another section, or all the sections may be blown simultaneously. It may be stated in passing that in the event the rear water-leg had no hollow stay-bolts,.it would be necessary to install a riser 5 with its nozzles .t to blow the section adjacent this leg.

Having described my invention, what I claim is 1. In combination with a boiler having a water-tube section composed of series of tubes disposed in superposed planes, and spaced apart, terminal headers communicating with said tubes, transverse battles for the tubes, a series of nozzles disposed over the tube area at one end of the water-tubes for projecting a cleaning fluid longitudinally with the tubes into the spaces between the tubes, series of nozzles for projecting a cleaning fluid transversely across the boiler into the spaces between the tubes, the

mingled fluids and the dirt dislodged thereby following the general direction of the draft whereby the same are expelled from the furnace of the boiler.

2. In combination with a boiler having a water-tube section composed of series of tubes disposed in superposed planes, and spaced apart, terminal headers communicating with said tubes, transverse batlies traversed by the tubes whereby the boiler is divided into inter-communieating sections, nozzles mounted over the tube area in one of the headers opposite the spaces between the tubes for projecting jets of clean ing fluid into said spaces in a direction lengthwise with the tubes, movable nozzles positioned opposite a section between two consecutive battles for projecting a cleaning fluid into the spaces between the tubes in a direction transverse of the boiler, the intensity of the respective currents being regulated to cause the resultant current to follow the general direction of the draft and carry the dirt out of the furnace of the boiler.

3. In combination with a boiler having a water tube section composed of series of tubes disposed in superposed planes, and spaced apart, terminal headers communicating with said tubes, transverse battles traversed by the tubes whereby the boiler is divided into intercommunicating sections, nozzles mounted over the tube area in one of the headers opposite the spaces between the tubes for projecting jets of cleaning fluid into saidspaces in a direction lengthwise with the tubes, nozzles oscillating about and disposed across a fixed axis positioned opposite a section between two consecutive bafiies, a riser adapted to sweep about said axis and coupled to the nozzles, and means for supplying a cleaning fluid under pressure to said riser and nozzles.
