FRED L. DORNBROOK, OF MILWAUKEE, WISCONSIN, ASSIGNOB, BY MESNE ASSIGN- MENTS, TO THE VULCAN SOOT CLEANER COMPANY, A CORPORATION OF DELA- WARE.
BOILER SCOT-BLOWER.
Application filed May 15,
T 0 all whom it may concern Be it known that I, FRnn L. DORNBROOK, of Milwaukee, Visconsin, have invented Boiler Soot-Blowers, of which the following is a specification.
This invention relates to devices for removing the soot or deposited carbon from the tubes of water-tube boilers. The object which I have in view is to provide a device which can be installed in a boiler of any width at moderate expense and by a simple manipulation will effectively clean the tubes or remove the soot therefrom mechanically in a thorough manner. Heretofore devices for such purpose have been devised consisting of steam-pipes mounted transversely or parallel to the tubes and having lateral nozzles through which steam jets were delivered. These devices, however, at least such of them as are known to me, have all proved defective and unsatisfactory in use in case of boilers provided with a heavy bank of tubes either very wide or very deep, for the reason that the jets from the nozzles do not effectively reach the surfaces of the tubes in such manner as to remove the soot therefrom. It is obvious that such jets acting in an individual capacity will drive merely in straight lines between the tubes, consequently cannot reach the surfaces of the tubes which lie behind other tubes, and it is these surfaces which largely carry the soot.
It is the main object of this invention to construct such a blower upon a new principle: to wit, by so directing the several jets that they will cooperate one with another, acting in such a manner as to produce atmospheric eddies or whirls in the intertube-spaces, which therefore produce cross currents, that is to say, currents lying transversely to the jets themselves, so as to reach every part of the surface of the tubes in a forcible manner and drive off the soot which is deposited thereon. I aim furthermore so to construct the device that it will completely-remove all the soot, not merely from the tubes, but from the boiler and flue surfaces, and thereby act as a cleaner for same;
and I have proved by long continued use that it will do so.
My invention embodies not merely this new principle but also other novel construc- Specification of Letters Patent.

tions which are auxiliary thereto, as will appear from the following detailed description and are embodied in my claims.
For the better understanding of my invention I have described in the following specification some of the most improved forms thereof, illustrating the same in the accompanying drawings, wherein Figure l is a transverse section on the plane 1 of awater-tube boiler having a number of my improved soot-blowers mounted in position therein, same being taken on the section-plane l of Fig. 2;
Fig. 2 is a longitudinal section thereof on the plane 2;
Fig. 3 is a partial section on the plane 1 on a larger scale, showing the upper part of the bank of water-tubes and a part of one of the soot-blowers;
Fig. 4 is a transverse section of one of the sootblowers on the plane 4 and on a still larger scale;
Fig. 5 is a fragmentary longitudinal section through a portion of the soot-blower pipe and one of the lateral nozzles;
Fig. 6 is a fragmentary side-view of another form of soot-blower, showing a somewhat difierent disposition of the nozzles to effect the same results; and
Fig. 7 is a longitudinal section through the rotary joint at the end of the sootblower pipe.
In these drawings the several reference letters designate the same respective parts in each figure.
For the sake of illustration I have shown in Figs. 1 and 2 a common type of watertube boiler and setting, the same comprising the boiler-drums A, bank of water-tubes B, headers C and D at front and rear completing the circulation through the watertubes and drums, and a superheating device comprising another bank of tubes E with headers F mounted above the boiler-drums A which receive the generated steam from the gas-space in said drums and deliver it thence to the steam-mains for consumption. The boiler-setting comprises the side-walls G; the top-closure or roof H; the frontclosure comprising the insulated wall 1, doors i and rolling curtain-doori the rearclosure comprising insulated wall J, doors j and j', and back-wall which is provided 7 60 through which tubes 13 to the combustion-ohamber 13 which is under the drums A, thence downwardly between the baffle-plates R and S into the 15 soot-chamber 14, thence upwardly again behind the baiiie-plate S to the flue 15 which is behind the wall P, thence to the overhead chamber 16 or part of the flue which lies horizontally along the top of the drums and 20 betweenthe superheater-tubes E, and finally out to the-chimney or stack through the flueopening 7L1 in the roof H, which is governed by the damper 7L The above description, it is to be understood, relates onlyto known features and not to those of my invention. Eight of the,
. latter are shown as installed, six of which are designated as a whole '1, and the other two,
which are on the under sides of the bank of tubes'B, are designated T as they present a slight difierence in their construction.
Each of the soot-blowers comprises a pipe t which is mounted either upon or under one ofthe banks of tubes and transversely thereto, so that it will be readily seen the blower is adaptable to batteries of boilers or tubes of any width whatever; Said pipe 25 is mounted preferably in the apertures of clips U, each clip comprising a pair of 40 plates united by a bolt-u and having at one end a pair of semi-cylindrical sockets 1& adapted to engage and be clamped by the bolt u 'upon one of the tubes B, and perforated at the other end with a hole' which forms abearing for the pipe "5 which passes through it. The pipe t carries a plurality of bifurcated nozzles t the peculiarity of whichis that'the two branches thereof are directed substantially along the oblique lines of theintertube-spaces as shown in opposite directions, so that the jets of the different nozzles cross each other on their way through said inter-tube spaces; and further, that the jets do not lie in the same plane but in planes somewhat separated from each other, in such manner that in crossing each other whirls or eddies are set up, which being transverse to the directions of the jets effectively reach the jets themselves do not pass. V 7 Two ways of effecting this condition are shown in the drawings; but I do not pretend that they arethe only ways in which it may with the supply of steam.

those inter-tube spaces Such means as illustrated comprise the hollow j0int-box or steam-box V, in which rotates the cyllndrical member 1V, having on one end: a socket head 10 into which the end ofithe pipe 25 screws, and on the other end a square Q02, adapted to receive a, crank X' provided with a handle 00 for turning it. The boX V has packing glands r on its'ends and a .centralsteam-chamber o with a V screw-threaded side-outlet a to receive. the s5 steam-supply pipe Y. The member IV has a bore 20 fora part of its length which opens laterally at w intothe chamber 42 whereby the member IV, and with the pipe t can be continuously rotated by means of the crank X without'interfering For providing against endwise movement a groove 10 is formed in the member W, which is engaged by the bossedends w of the screws w". "Any'other means for accomplishing the same result of rotating or oscillating the pipe '29 while supplying steam thereto may be adopted. At its-inner end said pipe is closed by a'cap t l The soot-blowers T which are below the bank B are arranged differently from the blowers T in that the arrangementofthe nozzles it does not follow a continuous helical line around thepipeit? but said nozzlesare disposed" all on one side of the pipe, shifting their angles in a zig-zag manner, an'd'means are provided (such as for example a stop-pin inthe groove w?) for limiting the .anglethrough which pipe 25 can be turned, so that at no timecan it be turned so faras to cause the jets to blow down. into the'soot-reeeiving chamber 14, because it is not desired to disturb orstir up the soot which isdeposited in said cham- In the same manner various changes and modifications in the constructions as herein shownmay be adopted without departing from the spirit of my invention and I wish it understood therefore that the latter is not otherwise limited than .by the proper scope of my claims.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. In a flue cleaner system, a fluid distributing. pipe having openings therein-.with
v the adjacent openings in different radial 65 be accomplished so'thatthe same principle planes, and a nozzle for each opening having an axial opening terminating at the outer end in a V-shaped passage to project spaced jets from each nozzle with the adjacent jets of opposed nozzles traveling in proximity to set up a vortex of whirling motion there between.
2. In a flue cleaner system, a fluid distributing pipe having openings therein with the adjacent openings in adjacent radial planes, and a nozzle for each opening having a Y-shaped passage to project spaced jets from each nozzle, with the adjacent jets of opposed nozzles traveling in proximity and free of contact to set up a vortex of whirling motion therebetween.
3. In a flue cleaner system, a fluid distributing pipe provided with outlets spaced apart along the pipe having their axes inclined toward each other and located in parallel planes so spaced that the nozzles will project spaced crossing jets in suflicient proximity to create a whirling action in the gases between the jets.
