BOILER-CLEAN ER.

SPECIFICATION forming part of Letters Patent No. 625,207, dated. May 16, 1899.

Application filed April 4,1898. Renewed March 15, 1899. Serial No. 709,200. (No model.)

To all whom it may concern:

Be it known that I, GoTTLoB F. SoHMID, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Improvements in Boiler-Cleaners, of which the following is a specification.

Myinvention relates to improvements in automatic boiler-cleaners, and has special reference to improvements in the device shown in Letters Patent No. 511,064, granted .to me December 19, 1893.

The present invention consists in certain novel features hereinafterfirstfnllydescribed and then specificallypointed outinthe claims.

In the drawings, Figure 1 is a perspective view of my improved cleaner attached to a water-tube boiler, parts of the wall and the steam-drum being broken away. Fig. 2 is a view showing the manner of attaching the cleaner to a series of boilers. Fig. 3 isaview of thecleaner detached,showin g a slight modification; and Fig. 4 is a detail view of the pan.

In carrying outmyinvention I employ three drums or cylinders A A A the lower horizontal drum A being provided with a blow-0E cook or valve B, as shown. Above the'drum A is arranged the smaller horizontal drum A, which is connected with the drum Abya short pipe or coupling 0. A pipe D, leading from the steam-drum of the boiler, enters the end of the sediment-drum A at the end opposite the blow-off cook or valve and is provided at a convenient point with a valve E. Just before it enters the drum the water-pipe D is joined by a mud-pipe F, also leading from the steamdrum of the boiler and provided with a valve G. These pipes D and F are connected with a pan H within the steam-drum, to which the water is supplied by the feed-water pipe I. This pan is supported on the bottom of the steam-drum by suitable legs or brackets in an inclined position, so that the Water will be forced to flow toward the back end of the pan and cannot stagnate therein. The top of the pan is open, except at the lower end, where it is provided with a skimming-plate J. This plate J serves to skim or separate the impure water containing the heavy sediment or impurities from the less impure water.

purer water will pass over the plate and into the water-pipe D, which is connected to the boilers.

The

pan at the rear end of the same and just above the lower edge of-the plate, while the heavy impurities and mud will be deflected into the mud-pipe F, leading from the bottom of the pan. This partial separation and precipitation of the impurities is accelerated by the heating of the feed-water, which occurs in the steam-drum.

From the pan the water and mud are carried into the sediment-drum A,where the mud and other. impurities are deposited on the bottom, the water rising into the reservoir-drum A, where it is collected. In this reservoir-drum there will be a still further purification of the water, as the impurities remaining therein naturally settle at the bottom. From the top of the reservoir-drum an elbow-pipe K leads into the vertical distributing-drum A at a point near the top of the same, and at the bend of the said pipe K, I connect the end of a steam-pipe L, leading from the steam-drum of the boiler and provided with a Valve M.

From the top of the distributing-drum a pipe N, having a valve 0, leads to the mud-drum of the boiler,so as to convey the purified water thereto. From the mud-drum the water circulates through the boiler in the usual manner. The bottom of the distributing-drum is connected with the top of the sediment-drum bya short pipe P, provided with a valve. Q, and the blow-off cock B may discharge into the open air, or, as preferred, into a suitable waste-pipe. The efficiency of the device will be increased if a valved connection be made between the return water-pipe N and the Waste-pipe; but this connection is not necessary.

If the cleaner is to be used in connection with a series of boilers,the steam-pipe is provided or formed with a series of branches R, leading from the steam-domes of the several The return water-pipe N will lead to a branch pipe S, communicating with the mud-drums of the several boilers and provided with check-valves T, so that the water may flow readily to each boiler, but cannot flow from one boiler to another. The branch pipes will also be provided with valves U, so

that the water may be shut off from any boiler of which will be provided with a valve V to control the flow of the water and cut out any one boiler without interfering with the use of any of the others.

If the device is to be applied to a boiler of the ordinary pattern, the pipe D will lead from the boiler near the Water-line and the return water-pipe will enter the same at or near the bottom thereof, the pan and the mudpipe being omitted.

The operation of the device will be readily understood. The Water enters the pan and, being there raised in temperature, will be partly relieved of its impurities, which will flow separately to the sediment-drum. In the sediment-drum further purification will take place and the water will rise into the reservoir-drum, the impurities tending constantly to fall to the bottom of the Water. From the reservoir-drum the Water passes into the distributing-dru m and thence into the boiler, as will be readily understood. WVhen it is desired to remove from the cleaner the impurities collected therein, the valves E, G, and O are closed and the valves B Q are opened. Steam will then pass from the steam-pipe through the several drums and drive the accumulation therefrom and out through the blow-off cock into the waste-pipe.

By connecting the steam-pipe directly to the elbow-pipe I secure the action of the steam-pressure directly on the accum nlations in the reservoir and sediment drums, where the deposit is greatest, and consequently obtain a rapid cleansing of the drums.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

l. A cleaner for steam-boilers consisting of a sediment-drum provided with a blow-0E cock at one end, a feed-Water pipe leading from the boiler to the opposite end of the sediment-drum, areservoir-drum above the sediment-drum and connected therewith, a distributing-drum above the sediment-drum and having a valved connection therewith, a pipe connecting the reservoir and distributing drums, a steam-pipe connected to said pipe and leading from the steam-space of the boiler, and a return Water-pipe leading from the dis-. tributing-drum to the boiler.

2. The combination with the battery of drums-consisting of a sediment-drum, a.rescr-.

voir-drum and a distributing-drum suitably connected, a pipenonveyi'ng the water from the distributing-drum to the boiler, a steampipe adapted to convey steam from the boiler to the drums, a pan within the steam-drum of the boiler, a feed-water pipe leading into the said pan, a water-pipe leading from said pan to the sediment-drum, and a mud-pipe leading from the pan to-the sediment-drum.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
