Amy, OakPark, 111., assignor to Vulcan- Soot 'Blower Corporation, a corporation of Pennsylvania Application The present invention relates to soot blowers oreleaners inwhich the tubular blower or clean-. ing element swings about an axis other than its own long axisand :has for its object to simplify and improve constructions of that type.
Viewedin one :of its aspects, the present in- 'vention maybe said te havefor its-object to -simplify and improve soot blowers adapted .to clean vertical tubes or lines installations-such,- for example, as air pr'eheaters -for furnac'es or the like I The various features' of novelty whereby my invention a is "characterized" will hereinafter 'be' pointed out with 3partici1larityin the claims; but, for a full understanding of myinvention and of its objects "and advantages, reference may be had to the following detailed description taken in connection with the accompanying -drawing, wherein'r v a Figure 1 is a vertical'section through an air preheater equipped with soot blow-ing apparatus embodying the present invention; Fig. '2 is a sectiorron line 2- 2 of Fig. l; 3 is-a topqilan viewyon a 'larger'sca-le, of one'endof the blower element, the flues being indicated "in dotted lines; and FigJ4 iS 'a transverse section, on instill larger scale, through the main portion-of the 'blower -element.- g A Referring to the drawing;A represents the-cas ing or housing of a heat interchanger which is shown as-being divided -day 'a vertical partition *B into two-compartments one bf which constitutes an ai-r duct,-and the other of which 'contains many vertical tubes or flues C arranged in transverse rows.

As is %customary in lCDIlStI'llCti-OIIS of this type, theverticaltubes or ,flues in=each transverse nrow are staggered with respectxto jthose ,invthe two adjacent rows. Thus, each nfithe oddxnum- .r-bered :tubes or flues, readingfrom the fileitiin Fig. 1, may he indshe Jfront row, while athe: others :are

as viewed in Fig. 1. The arrangementiof {the znozz'lesrii-snoi icfoursegrsueh: that :the vblower.ele- Ement my. be iplacedinzcleaning lorgblowingqposi tion with respect to two adjacent transverse rows of vertical tubes or flues'and thus cause these tubes or flues to be cleaned two rows at a time.
In moving the blowerelement across its entire sweep so as to cause all of the vertical tubes or flues within its range to be cleaned, the direction of the jets discharged by the nozzles will naturally vary according to the point at which the blower element happens to be in its arc of'travel, if this element be fixed to the supportingarms.
Obviously, this would prevent the jets from being discharged properly into all of the vertical tubes or flues; I have therefore provided means for turning the blower element relatively to its supporting arms, while these arms are swinging back and forth about the axis of the pipe I, whereby the jets will always be discharged in the proper direction to enterthe vertical tubes orcorresponding stationary pair of ears I! is arod or strut l8,'pinned to both pairs of ears. Conse-' quently, when the pipe I turns, the connections for the lower -ends=of-.the rods or struts l8 being fixed, theblower element must turn about its long axis. In other words, if a radiusfrom the axis of the blower element through the pointo-f con.-
nection between one of the rods or struts and the ears I 5 is horizontal in a given position of the parts,this radius will always remain horizontal throughout the entire range of swinging movements of the'device, and the directions in which the jets-are discharged will always be parallel with the directions in any other position of the blower. element. I
The pipe. I is provided with a second pair of radial arms l9, l9 exte'ndingdownwardly therefrom; thesearms being provided with weights, as indicated at 20, at their lower ends. The weighted arms balance the tubular'blowing element'and the means for supportingtheysame from the pipe I, so that the device'as a whole tends to remain in any. angular position into which it may be moved.
\ Some of therverticaltubesor flues along the sides. of the" compartment"lcontaining the same or flues that cannot be reached by the overlie what may be termedthe hollow supporting heads 2| onthe upper ends of. the tubular arms II. In order thatwthese tubes tor flues .may be properly blown, I provide the main blower provided with suitable nozzles -231that discharge jets into the lower ends of thosevertical tubes jets from the main blower element.
While I have'illustrated and described with particularity .only a single preferred form of my Iinvention,I do not desire to be limited to the exact structural details thus illustrated and'described; but intend to cover all forms and arrangements which come withinthe definitions. of
my invention'con tituting the appended claims.
