BOILER-CLEAN ER.

SPECIFICATION forming part of Letters Patent No. 662,524, dated November 27, 1900.

Application filed Febrnaryti, 1900. Serial No. 4,261. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. DAMMANN, a citizen of the United States, residing at Athens, in the county of Menard and State of Illinois, have invented certain new and useful Improvements in Boiler-Cleaners, of which the following is such a full, clear, and exact description as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to boiler-cleaners of that class in which the steampressure within the boiler is utilized 'to remove from the boiler the sediment accumulated therein by blowing out the same through a suitable blow-off pipe.

The purposes of my invention'are toprovide a boiler-cleaner so constructed and arranged as to remove simultaneously from different parts of the boiler-surface the sedimentaccumulated thereon, to provide simple and effective means to guide the sediment into the blow-off pipe, to provide means of improved construction for supporting the boiler -cleaner within the boiler, to provide a boiler-cleaner having a multiplicity of branches, and to provide means whereby one branch or member of the boiler-cleaner may be operated independently of the other branch or branches thereof.

With these ends in View my invention consists of the novel features of construction and combinations of parts shown in the annexed drawings, to which reference is hereby made.

Referring to the drawings, Figure 1 is a side elevation of the complete boiler-cleaner in position in a boiler, only so much of the boiler being shown in sectional view as is necessary to illustrate the connection of the boiler-cleaner therewith. Fig. 2 is a vertical longitudinal section through the boilercleaner. Fig. 3 is an enlarged detached perspective View of one of the induction-plates. Fig. 4 is an enlarged vertical longitudinal section through one of the supports on the line 4 4: of Fig 1.

Similar letters of reference designate like parts in all of the views.

The boiler-cleaner may be applied to and used with any of the types of boilers in common use.

In the drawings I have illustrated a boilercleaner having two branches parallel to the lower surface of the boiler and having two induction-plates; but the boiler-cleaner may be constructed with a single outlet-pipe and a single induction-plate or three or more pipes having corresponding induction-plates may be used without departing from my invention or sacrificing any of the advantages thereof.

The boiler-cleaner in its preferable form consists of two parallel outlet-pipes A, one above the other, as shown. Nipples I; extend through the boiler-head C and through a reinforcing-plate D, which is suitably secured to the boiler-head. Pipes A and A screw into the body of globe-valves E. OouplingsF connect the pipes A and A with the nipples B, and one of the couplings binds on the inner surface of the boiler-head and the other coupling binds on the outer surface of the reinforcing-plate D, so as to form a steamtight connection of the pipes with the boiler. The induction-plates G are cylindrical for a part of their length and have a reduced screwthreaded part 9 and a broadened and slightlyconcaved forward part g integral with the bodyof t-heinduction-plate. Screw-couplings G connect the induction-plates G with the pipes A. An elbow A screws onto the outer extremity of the upper pipe A A T-coupling A screws onto the outer end of the lower pipe. A pipe A screws into the lower end of the elbow A and into the upper end of the T-coupling A. A blow-off pipe A screws into the lower end of the T-coupling A.

Rectangular plates H, having their upper surfaces shaped to conform to the inner sur' face of the boiler-shell, are suitably secured to the boiler-shell. Rings H 'fit loosely around the pipe A, and rods 11 screw into the plates H and into the rings H and serve to support the pipes A within the boiler, so as to prevent accidental displacement thereof, but so as to permit longitudinal movement of the pipes due to the contraction or expansion of the pipes.

It will be observed that the supports de scribed support the pipe from the upper part of the boiler-shell. There is practicaladvantage in thus supporting the pipes, because if the supports were placed on the lower surface of the boiler-shell contiguous to the fire-surface they would interfere with water circulathe induction-plates arrest the upward movement of the sediment and guide the sediment into the pipes A.

There is practical advantage in employing a multiplicity of pipes and induction-plates in that the operation of the boiler-cleaner may by this means be localized and made more effective and also in that those parts of the boiler which are most subject to fouling-for example, the sheets which are directly over the fire-boxmay be cleaned expeditiously and With the least waste of steam and water.

In case a boiler-cleaner having two induction-plates, as shown, is used one of the induction-plates is preferably placed directly over the fire-box and the other over that part of the boiler immediately behind the fire-wall.

By employing two valves E either one of the pipes A may be used independently of the other, or both may be used together, as occasion may require.

In practical operation the valve or valves E are opened, permitting the escape of steam through the pipes A and A to the atmosphere, thus agitating the water in the boiler and stirring up the sediment under the induction-plates and causing it to rise into contact with the plates, by which it is guided into the pipes A and is thence blown out through the pipe A After cleansing the boiler, as described, the valves E are again closed.

Having fully described my'invention, what I claim as new, and desire to secure by Letters Patent, is v 1. In a boiler-cleaner, the combination of a reinforcing-plate secured to the boiler-head, nipples passing through the boiler-head and through said plate, couplings at the ends of said nipples abutting against the boiler-head and said reinforcing-plate, pipes screwing into the couplings inside of the boiler, curved induction-plates, and screw-couplings connecting said induction-plates with said pipes, as set forth.

2. In a boiler-cleaner, the combination of nipples passing through the boiler-head and through a reinforcing-plate secured thereon, couplings screwing onto said nipples and abutting against the boiler-head and against said reinforcing-plates, pipes screwing into the couplings within the boiler, induction plates connected with said pipes, pipes screwing into the couplings external to the boiler and having a common outlet, and valves controlling the opening and closing of said pipes, as set forth.

In witness whereof I have hereunto subscribed myname at Athens, Illinois, this 23d day of December, 1899.

GEORGE W. DAMMANN.
