FEED-WATER PURIFIER.

SPECIFICATION forming part of Letters Patent No. 457,157, dated August 4, 1891.

Application filed June 30, 1888- Serial No. Z'HLGQZ. (No model.)

To all whom it may concern.-

Be it known that I, JOHN J. HOPPES, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Feedater Purifiers, of which the following is a specification.-

My invention relates to improvements in feed-water purifiers for steam-boilers; and it particularly relates to that class of purifiers which are connected to the steam-boiler and supplied with the live steam therefrom, so that the conditions to which the water is subjected in the purifier are substantially the same as I 5 those in the boiler proper.

The object of my invention is to provide means for carrying off air or gases that collect in the top of purifiers of this character from the heating of the water and the incrus- 2o tating and other substances therein contained. This I accomplish by connecting to the purifier a pipe leading to the boilenfeeder or other device requiring a steam-supply, and thus create a circulation through the purifier 2 5 by which any air or gases therein contained will be drawn off.

In the accompanying drawings, which form a part of this specification, Figure 1 is a perspective View of a feed-water-purifier mechanism embodying my invention. Fig. 2 is a longitudinal sectional view, also in perspective, of a purifier, showing the arrangement of the connections thereto.

Like parts are indicated by similar letters of reference throughout the several views.

In the said drawings, A represents a steamboiler of ordinary construction. B is a steamdrum attached thereto.

O is a purifier, which may be of any Well- 0 known construction adapted to be connected direct to the boiler and supply with steam therefrom. The purifier O is connected directly to the steam-drum B by a pipe a. The feed-water enters through a pipe I; and pass- 4 5 ing over a series of pans or shelves, as the case may be, of the purifier, is discharged into the -boiler near the bottom or below the water line thereof through the pipe-connection 0. Since the pressure in the purifier c is substantially the same as that in the boiler A, means must be provided for forcing the feed-water through the supply-pipe 5 into said purifier.

caused from thecondensation of the steam therein owing to a constant supply of feedwater to said heater. The feed water for steam-boilers contains in many cases large quantities of foreign matter, which, when heated, give off carbonic -acid gas, hydrochloric acid gas, muriatic fumes, or other gases. Inasmuch as there is a constant flow of steam from the boiler to the purifier, these gases collect in the purifier, and if not removed fill the purifier to such an extent as to materially interfere with the purifying effect of the steam therein. To overcome thisdifficulty, I provide an additional connection to the purifier C,which leads direct to the boilerfeeder or other steam-usin g device,which thus continually drives off the gases, air, or steam from the said purifier, creating a circulation therein which keeps the same at all times full of live steam adapted to act upon the feed- Water therein. In Fig. 1 the preferable method of forming this connection is shown. It consists in running the supply-pipe d, which leads to the boiler-feeder D, to the purifier 0, through a branch pipe 01, connected with a T d, which is also connected by a pipe (1 to the boiler-supply, the pipes d and (Z', respectively, beingv supplied with stop-valves d and (1 by which the steam-supply for the feedpump may be drawn either from the boiler or from the purifier, as desired, or partly from both. By this arrangement if the purifier in any event is cut oif for any reason the boilerfeeder may receive the steam-supply direct from the boiler. I preferably make the connection with the boiler-feeder, since the supply of feed-water for the purifier is dependent upon the said boiler-feeder, and as the gases collected in the purifier come from the watersupply pipe and said boiler-feeder, theaction of the pump which supplies the said gases will also furnish the means for removing the same.

Having thus described my invention, I claim 1. The co1nbination,with a steam-boiler and a feed-water purifier connected together by suitable steam-pipes, of a steam-pump having a steam-pipe connection with said purifier for producing a circulation in said purifier and thus removing the gases, substantially as specified.

2. The combination of a steam-boiler, a purifier connected thereto by a suitable steampipe and also connected to the feed-water pump by suitable pipe connections, and a discharge-pipe from said purifier connecting the purifier with the boiler below the'water-line, substantially as; specified.

3. In combination with a steam-boiler, a
