BOlLER-CLEANER.

SPECIFICATION forming part of Letters Patent No. 710,843, dated October 7, 1902.

(No model.)

To all whom, it may concern.-

Be it known that I, JOHN W. OoNE,a citizen of the United States, and a resident of Barnesboro, in the county of Cambria and State of Pennsylvania, have invented a new and Improved Boiler-Cleaner, of which the following is a full, clear, and exact description.

My invention relates to improvements in boiler-cleaners; and the object that I have in View is the provision of a simple and efcient construction adapted to blow off impurities at the surface of the Water in the boiler and to discharge sediment at different portions along the length of the boiler at the bottoni thereof.

The improved cleaning device may be easily supplied to a boiler at a low cost, and it is provided with valve devices adapted to control the operation of eliminating the sediment at the bottom of the boiler through a series of successive collecting tubes or branches.

With these ends in view the invention consists in the construction, arrangement, and combination of parts, which will be hereinafter described, and the actual scope of the invention will be defined by the claims.

Reference is to be had to the'accompanying drawings, forming a part of this specication, in which similar'characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation of an ordinary steam-boiler, illustrating my improved cleaner devices applied thereto, the plane of the section being indicated by the dotted line 1 1 of Fig. 2. Fig. 2 is a vertical transverse section in the plane of the dotted line 2 2 of Fig. 1. Fig. 3 is an enlarged sectional elevation through the collecting and discharging devices, parts of said devices being broken away; and Fig. 4 is a vertical cross-section on the line 4 4 of Fig. 3.

In Figs. 1 and 2, 5 indicates an ordinary boiler having the steam-dome 6 and the series of dre-tubes 7; but the boiler may be of any preferred construction. In the lower part of the boiler, preferably below the series of nre-tubes 7 therein, is a horizontal discharge pipe or tube 3. This pipe or tube lies quite close t0 the bottom of the boiler at the place where the sediment is liable to collect, and the said discharge tube or pipe extends longitudinally of the boiler, preferably from one end thereof to and through the other end. The extended or projected end of this pipe or tube may be joined to one headof the boiler by any suitable water-pipe connection, (not shown,) and said extended end of the tube is carried through the masonry-wall 9 or the boiler-front, as indicated more clearly by Fig. 3. The discharge tube or pipe is provided at points along its length with a series of collecting branches 10, the same depending from the lower side of said pipe or tube 8 and curved, as shown by Figs. 2 and 4, so as to terminate in open mouths in the vertical plane of said tube 8. The curved collecting branches 10 'lit very closely to the bottom of the boiler, as shown by Figs. 1 and 2, and

these branches are thus adapted to extend into the sediment which collects at the bottom, this making provision for the thorough removal of thesediment from the lower part of the boiler.

The inner end of the tube or pipe Sis shown by Fig. 3 as having a head 11, which serves to close said end of the pipe; but the outer projecting end of the tube which is carried through the wall or lfront 9 is provided'with a depending discharge-leg l2 and with a stuifing-box 13 of any suitable construction. This dischargeleg is disposed in an inclined position to the length of the tube or pipe 8, and any sediment which accumulates in the pipe is adapted to pass through this leg.

In order to control the passage or escape of the foul matter from the boiler, I employ a valve 14 of any suitable construction, said valve being adapted to open or close the inclined discharge-leg 12.

15 designates a valve-tube, which is snugly iitted within the discharge pipe or tube S and is adapted to be shifted therein by moving the valve-tube endwise or turning it on its axis. The valve-tube is provided with a series of ports 16, which are placed at variable distances therein and in diiierent positions, so as to register individually with different collecting branches 10, and with a verticallyextending tube, which Will be hereinafter doscribed. The valve-tube l5 is furthermore provided at one end with a skeletonized head or spider 17, the latter being made fast to the IOO tube in any suitable way. From this spider extends a spindle 18, which passes through the stuffing-box 13 at the outer end of the discharge tube or pipe, and on this spindle is secured a hand-wheel 19, adapted to provide a convenient means for the operation of the valve-tube.

20 designates an upstanding pipe, which is provided with an elbow 21 at its lower end, the latter being secured to the discharge pipe or tube 8 at a point between two of the co1- lecting branches 10 thereof. The upstanding pipe 2O terminates in a horizontal branch 22, which is adapted to lie at the level of the water in the boiler, and the end of this branch 2 is open, so that any iloating refuse on the surface of the water will easily pass into the tube 22 and the pipe 20, so as to be discharged from the pipe or tube 8 and its branch 12 when the valve 14 is open.

In the service of my improved boiler-cleaner the tube 15 is adjusted by the stem 18 and the hand-wheel 19, so as to bring one of its ports 16 into registration with the lower end of the upstanding pipe 20, which is fastened to the discharge-pipe 8. This adjustment of the valve-tube allows the surface refuse to easily escape through the pipes 22, 21, 8, and 15 when the valve 14 is open in the dischargeleg 12. If it is desired to remove sediment from the bottom portion of the boiler, the valve 14 being closed the hand-wheel 18 is to be manipulated, so as to turn the valve-tube 15 or to shift it lengthwise within the discharge-tube 8. This operation brings one of the ports 16 into registration with one of the collecting branches 10, and the sediment at one particular place on the bottom of the boiler is free to pass through the branch 10 into the tube 15 through the spider 17 thereof, and thence make its exit by the inclined leg 12, the valve 14 being of course open. The valve-tube 15 may be again adjusted, so as to bring another of its ports 16 into registration with another of the collecting branches 10, and this makes provision for the discharge of the sediment from a different portion of the boiler. This ope ration may be continued until all the branches 10 shall have been brought into service, and thus the sediment along the entire length of the boiler may be removed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A boiler-cleaner provided with a discharge pipe located longitudinally in the lower part of a boiler and provided with a series of inlet branches and with exteriorlylocated discharging means, and a valve-tube snugly fitted within said discharge-pipe and shiftable endwise and axially therein, said valve-tube having openings arranged to be brought into registration individually with the inlet branches by an endwise or axial adjustment of said valve-tube.

2. A boiler-cleaner provided with a discharge pipe having an exteriorly located valve-leg, and a suitable stuliing-box which is located in the plane of said pipe, a series of inlet branches extending from the pipe and communicating with the passage therein, a valve-tube tted within said pipe and having a series of inlet-ports, and a stem which passes through said stuffing-box, and a suitable handle attached to the stem and adapted to be manipulated to adjust the valve-tube by moving it endwise or axially within the discharge-pipe.

3. A boiler-cleaner comprising a dischargetube having a series of depending curved branches, and a single valve-tube which is adjustable and shiftable within said discharge-tube and is adapted to establish communication between said individual branches and said discharge-tube.

4. A boiler-cleaner provided with a discharge-pipe having a series of depending inlet branches and an upstanding pipe which terminates in a horizontally-opening mouth at or near the Water-line of the boiler, a valvetube fitted within said pipe and provided with individual openings arranged to be brought into registration with either of said dependingl branches or with the upstanding pipe, and means for adjusting the valve-tube endwise or axially within the discharge-pipe.

5. A boiler-cleaner, comprising a dischargetube having at its exposed end a stuffing-box and a valved discharge-leg, a series of depending collecting branches spaced at intervals along said discharge-tube, an upstanding collecting branch also attached to the discharge-tube, a valve-tube shiftably and adjustably fitted within said discharge-tube and provided with ports arranged to individually communicate with said collecting branches, and a stem passing through the stuing-box and united tothe valve-tube,sub stantially as speciied.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
