LIVE-STEAM PU RIFIER.

SPECIFICATION 'Ofming part of Letters Patent N0. 434,324, dated August 12, 1890.

' Application tiled J une 9, 1890. Serial No. 354,736. (No model.)

To all whom it may concern.-

Be it known that I, RALPH B. DAY, a citizen of the United States, and a resident of Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Live-Steam Purifiers and Feed-Water Connections, of which the following is a specification.

My'invention relates to an improved method 1o of connecting feed-Water heaters and purifiers which employ live steam from a boiler to heat the feed-Water.

The object of my invention is to provide for the escape of deleterious gases which are I5 generated in the purifier, so as to prevent them from remaining in the purifier. I have also found from experience that when only one connection is made from the purifier to the boiler the proper circulation is not ob-' 2o tained. The deleterious gases are chiefiy evolved from the Water by the separation of the mineral deposits. These are apt to condense and corrode in the purifier unless proper means are provided for avoiding it. I therefore obtain two results, first, in preventing the corroding of the purifier, and, second, in providing' a better circulation, and consequently getting a high heat on account of the improved circulation of the water in the purifier.

The various features of my invention will be fully setforth in the description of the accompanying drawings, making a part of this specification, in whichd Figure 1 is a side elevation of my improvement applied to a boiler in position for use. Fig. 2 is a modification of Fig. l.

A A represent battery-boilers.

-B represents a steam-dome, and C the puri- 4o fier, which may be of any approved construction for purifying feed-Water.

1 represents a steam-pipe connecting the dome with the purier C. This pipe furnishes the necessary steam for heating and purifying the feed-Water.

2 represents a steam-pipe leading from the purifier to the pump D.

3 represents the feed cold-water pipe leading likewise from the pump to the purifier.

5o 4 represents a Water-supply pipe leading from the purifier to the boiler for supplying the saine With the heated and purified feed Water.

In the modification shown in Fig. 2 the same general construction and arrangement are employed; but instead of having the pump take its steam from the purifier I make a twopipe connection between the steam-pump D and the purifier O. 7 8 represent these pipes, which are connected by means of the pipe 5. 6o

6 represents a steam-pipe tapping pipe 5 and driving the pump D. This will accomplish the same result as that shown in Fig. 1, because the deleterious gases evolved from the feed-Water in the purifier O will escape through 8 into pipe 5 and be taken otf by pipe 6 to the pump. In both cases the deleterious gases pass oft with the steam tothe pump and are exhausted in the air. Owing to the high heat and rapid escape of the gases, 7o they do not condense, and hence do not Work a deleterious effect as where they are allowed to remain in the purifier.

By means of both the above-described arrangements I am enabled to secure the proper 7 5 circulation between the purifier and boiler and avoid the deleterious gases with the steam. It is obvious that pipe 1 may tap the boiler directly above the Water-line, instead of tapping the dome. I have not shown valve- 8o cocks for closing these pipes in case the pump is not employed temporarily for various purposes, as they are of ordinary form of construction and may be employed or otherwise, as occasion requires. Y 85 Having described my invention, what I claim is l. The combination,with the boiler and feed- Water purifier C, suitably connected together by steam-pipes, of the steam-pump D, having 9o a steam-.pipe connection with the purifier for carrying ott the escaping gases generated in the feed-water, substantially as herein specified.

2. In combination with the steam-boiler, the purifier O, connected thereto by a steampipe l and to the feed-Water pump by suitable pipe-connections, and the hotrfeed-Water pipe 4, connecting the purifier With the boiler below the water-line, substantially as specified.

3. In combination with the boilers A, the
