GENRY A. CHAPMAN, OF STRAWBERRY POINT, IOWA.

BOILER-CLEANER.

SPECIFICATION forming part of Letters Patent No. 273,026, dated February 2'7, 1883. I

Application filed May 11, 1882. (No'modelJ To all whom it may concern Be it known that I, GENRY A. CHAPMAN, of Strawberry Point, in the county of Clayton and State of Iowa, have invented certain new and useful Improvements in Boiler-Cleaners, of which the following is a full, clear, and exactdescription. I

My invention consists of a pipe-connection of the boiler through the end or side, at or about the low-water level, with an outside drum, which is below the top of the water in the boiler, said drum being connected to the boiler at the bottom in'any simple way, with stop-valves in connecting-pipes when necessary, and blow-offcock to the drum, the object being to establish a circulation of water from the surface, or thereabout, out into the drum and back into the boiler, for taking off the sediment thrown up to the surface of the water in the boiler by the ebullition of the water into the drum, where it will settle to the bottom in the more quiet water, from which it may be blown off from time to time. The circulation thus provided for will be constant and uniform as long as there is any fire in the furnace, so that all the water contained in the boiler will flow through the drum, and the purifying process will be continuous and eflective. The pipe entering the boiler at the waterline may be continued inside of the boiler to the center, and terminate with a funnel-mouth opening in the direction to receive the water in which a current may set. While the outflow-pipe should enter the boiler about at the low-water line, so that water will pass instead of steam, still no harm will be done in case the water mayfall too low to flow, for no waste of steam occurs. The apparatus maybe arranged in various ways, according to circumstances of the case or the judgment of the constructer, as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a transverse section of a horizontal tubular boiler, with my improved sediment-removin g apparatus according to one arrangement in which it'may be applied. Fig. 2 is a side elevation of a fire-box boiler, showing another form of apparatus adapted to it; and Fig. 3 is a side elevation of an upright boiler withan arrangement adapted to it.

A represents the boiler, and B the outflowpipe, said pipe being connected to the side of the boiler at the low-water line, or thereabout, and either terminating thereat orextending inward, as shown at O, and terminating in a tunnel-mouth, D. In Fig. 1 this outflow-pipe enters the upper end of a stand-pipe, E, on Which a deflector, F, sends the water downward before passing on through pipe G to the drum H, and said stand-pipe has a blow-off cock, I, for discharging the mud. The drum is connected by the pipe J. with the bottom of the boiler, and it will have a blow-01f cock and hand-holes for cleaning it out.

The stand-pipe may be dispensed with, the pipe 13 connecting directly with the drum, which, in the case bf the fire-box boiler, Fig. 2, may be located under the waist of boiler, and connected to the bottom of the fire-box.

In the upright boiler the mud-drum may stand by the side thereof and connect with the boiler, as shown in Fig. 3, or in any other approved way. 1 do not limit myself to any particular arrangement.

'I have ascertained by practical use of this improved sediment-remover that it will effectually prevent the deposit of scale, and will also cause the removalof scale already formed by carrying off the particles detached by the action of the heat and water, along with the matters flowing in with the feed-water, and carried off as above described.

Having thus fully described my invention, I

.elaim as new and desire to secure by Letters Patent- In a boiler-cleaner, the combination, with the boiler A and drum H, having a discharge pipe and arranged beldw the boiler, and connected to the bottom thereof by the pipe J, of the open-ended water-pipe B, having the funnel-shaped mouth I), and arranged about on the same plane with the low-water level of the boiler, its outer end being connected, through a settling-chamber, to the pipe G, leading to the mud-drum H, all constructed, arranged,

and operating as shown and described, and for the purpose set forth.

GENRY A. CHAPMAN.
