BOILER-TUBE CLEANER.
SPECIFICATION forming part of Letterslatent No. 608,418, dated August 2, 1898. Application filed January 8, 1898. Serial No. 666,022. (No model.)
T all whom, it map/concern:
Beit known that I', FRANCIS W. BRADLEY, a citizen of theUnitedStatesof America, residing at Sharpsburg, in the'county of Alle-7 gheny and State'ofrPennsylvania, have invented certain new anduseful Improvements in Boiler-Tube Cleaners, of .which the follow; ing is a speciication, reference being had therein to the accompanying drawings.
This invention relates to certain new and useful improvements in boilertube or fiue cleaners, and has for its object to provide a flue-cleaner that is forced through the tube or flue by means of a hose through which the water passes through the cleaner and into the tube to assist in the removal of the scale or other sediment that has adhered to the inner face of the tube or flue.
The principal features of my invention consist of a cylinder Vwithin which is arranged a sleeve or hub which has a turbine formed thereon, the latter, receiving lthe impulse of the water, communicating a rotary motion to the sleeve or hub.- T0 kthe ,upper end of this sleeve or hub is attached a series of pivotable arms carrying interchangeable cutters which are thrown by the centrifugal force of the sleeve or hub into contact with the inner periphery of the tube or fine for the' purpose of cutting the scale or other sediment that has accumulated thereon and which is washed out of the tube or --iiue after being loosened by means of the water passing into the cleaner. Y n
The invention aims to construct a iiuecleanerof this class provided with pivoted arms and cutters which will conform to the size of the tube or flue and which will readily permit the withdrawal of the cleaner from the flue after the same has been driven through to perform the cleaning purpose.
Vith the above and other objects in the invention nally consists in the novel conf struction, combination, and arrangement of lar parts throughout the several views, in which`-' j :Figurel is, al perspective View 'of umy improved flue-rcleaner, showing a portion of the hose attached thereto. Fig; 2 is a perspective view of the sleeveor,hubanditsturbine. Figs. 3, v4,and 5 are detail perspective views of the'interchangeable cutters or knives, the two -latterviews being modifications of Fig. 3. Fig. G'is an' end or edgeview of one of the cutters or knives. Fig. 7 is aglongitudinal sectional view of the cleaner. ;Fig. S is a similar View showing the cylinderI extended so as to limit the radius to which the arms may be extended. Fig. 9 is a transverse vertical sectional view. Fig.l l0 is a rear View showing the removable arms inposition for supporting the rear of the cleaner, and Fig. 11 is a detail perspective view of one of these removable arms.
Referring now tothe drawings ,byA reference-iigures, 1 denotes the cylinder, within which the sleeve or hub and its `turbine are arranged. In lthe rear of thisV cylinder is secureda plate 2, whichis provided witha projecting angethereby forminga means for 'securing the plate vrigidly within thecylinder by means of screws engaging ,through the saidl cylinder and Iiange-or4 anyy other 'suitable fastening means.- This plate is provided with a central aperture 4to receive the shaft 5, which carries the sleeve or hub 6, the latter having formed integral therewith at its rear end a series of buckets arranged circumferentially around the sleeve or hub, and
thereby forming a turbine 7 to receive the water as it passes through the inclined apertures 8 in the plate 2. The sleeve or hub G is provided at its forward end with suitable ball-bearings 9, the bearings l0 for which are retained rigidly in their position by means of a lock-nut 1l, and at its rear end similar ball-bearings l2 are provided for this sleeve or hub, their bearings 13 serving the triple purpose of bearing for the shaft 5, a nut to lock the same inl position, and a bushing which abuts against the inner face of the plate 2te hold the sleeve or hub away from vthe said plate, andthus retain the turbine at a properdistance to receive the impulse of the water vpassing into the cleaner, the shaft IOO 5 being retained. in its position by means of the nut 13 on its rear end. g
Formed integral with the sleeve or hub at its forward end is a series of flanges or lugs Il., arranged circumferentially around the sleeve or hub and to which the pivotable arms 15 are pivotally secured. These arms are bifurcated on each of their ends, thereby forming jaws 1G to engage the aforesaid tlanges or lugs 1l and to which the arms are secured by means of asuitable screw or other device 17. In the outer ends of these pivotable arms are pivotally secured by means of a screw or other fastening device 1S the eutters or knives 1.0, as shown in Fig. 3, or these knives may be made of the forms 2O or 2l, as shown in Figs. -land 5.
ly formingtheknives withthe four notched or serrated corners 92 and the beveled edge 223, as shown in Fig. El, these knives or cutters may be changed within the arms so as to use the four edges of the same for cutting the soot or other sediment from the inner face of the flue. It will readily be observed, however, that various forms of these knives or cutters may be employed.
Secured to the rear end of the cylinder is a cap 2l, which is held in position by means of screws or bolts 25, engaging the apertures 2G provided therefor inv the perforated plate 2, said cap having a nut 27 formed integral therewith for the reception of the nipple 2S of the water-hose tl. This construction forms a chamber 30 between the rear plate of the cap and the perforated plate 2, and as the quantity of water passing through the hose into this chamber will be greater than can be carried off through the perforations in the plate 2 the same will naturally be forced outwardly into the flue at the joint of the cap if with the cylinder, and the force of the water thus spraying outwardly around the entire circumference of the cleaner will serve to elevate this end of the cleaner and retain the same at the same height as is assumed by the forward end of the cleaner, which will of course be regulated according to the distance that the pivotable arms have been thrown outwardly by the centrifugal. force imparted to the same through the sleeve or hub and its turbine.
In Fig. 2 I have shown the lugs or flanges lt provided at their inner end with a projection It, which serves to limit the closing movement of the reversible arms and their cutters, and in Ifig. S I have shown the cylinder 1 extending outwardly at its forward end over these lugs or flanges 1.4.-, so as to limit the outward movement of the aforesaid pivotable arms and their cutters.
In Fig. S I have also shown a slight modification in the construction of the cylinder, the cap being formed integral with the cylinder, and the perforated plate 2 resting upon a shoulder 31, formed within the cylinder, where it is secured by means of screws or other suitable device. In this construction the uut Q7 is constructed in the inner instead of the outer face of the rear plate, and when the hose 2!) is connected within said nut the water-chamber 30 will be perfectly tight, so as to prevent any escape ofthe water, except through the perforated plate 2. This construction is onlyadapted for small-sized tubes or tlnes not exceeding in diameter the distance to which the reversible arms may be extended and which is limited by reason of the cylinder extending outward a short distance from the same. For the purpose of assisting in retaining the rear end of the cleaner at the same elevation as the forward end where this form of closed water-chamber is employed I provide a series of removable studs or supports 32, having a screw-threaded shank 33 on one end, which. engages apertures provided therefor at asuitable distance around the circumference of the cylinder. These may be readily detached and the cleaner used without the same when desired.
The perforations provided in the plate f3 are preferably arranged at an incline, so as to carry the water into direct contact with the buckets of the turbine, and as the pressure of this water acts upon the turbine the sleeve or hub is thereby revolved, while the pivotable arms, being pivotally connected to the sleeve or hub, are forced outwardly by reason of centrifugal forccand the cutters or knives brought into engagement with. the inner peripheryof the llne or tube, so as to effectively remove the soot or sediment therefrom.
rlhe cleaner is readily forced through the tube by means of the hose attached thereto and as readily withdrawn by the same means, while the water coursing through the cleaner and escaping into the tube serves to effectually wash out all the sediment that has been loosened by the action of the cleaner.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. Aflue-cleanercomprisingacylinderhaving a series of removable studs or supports arranged on its periphery, a plate secured. at one end having inclined apertures, a cap secured to said plate forminga water-chalnber, a water pipe connection with said waterchamber, a turbine arranged in said cylinder and operated by water passing through the water-pipe connection and perforated plate, a series of pivoted arms carrying cutters which are forced into engagement with the inner face of the flue or tube by centrifugal force attained through the operation of the turbine, substantially as herein shown and described.
