APPARATUS FORSTERILIZING AND PURIFYING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 546,015 dated September 10,1895.

Application filed December 20, 1894:- Serial No. 332,485. (No model.)

To aZZ whom it may concern:

Be it known that I, LEICESTER P. KING, of Cincinnati, county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Apparatus for sterilizing and Purifying Liquids, of which the following is a specification, reference being had to the are companying drawings.

The object of my invention is to produce an improved condenser, reboiler, and filter adapted to form a part of an .ice machine and to thoroughly purify the water required to be converted into ice.

In the accompanying drawings, Figure I is a side elevation of my apparatus. Fig. II is a longitudinal vertical section thereof. Fig. III is a section on the line 3 3 of Fig. I; Fig. IV, a section on a line at 4 of Fig. I.

Referring to the figures on the drawings, 1 indicates a filter-chamber, which is preferably made of galvanized sheet-iron of suitable shape and dimensions, and 2 indicates a similarly-constructed reboiler. As a feature of construction the outer walls of the filterchamber and reboiler are preferably provided with abutting annular flanges 3 and 4, by which they may be joined together. For the purpose of uniting them"angle-pieces and angle-heads 6 upon legs 7 may be employed, the angle-pieces and angle-heads being respectively united by bolts 8, which serve to draw the flanges 3 and 4 together and firmly unite them. A bottom 9 may be riveted into the walls of the reboiler a little above the flange 3. A common transverse partitionplate 10 is provided above the reboiler for the bottom of a steam-condensing chamber 11. The steam-condensing chamber is provided with abutting annular flanges 12 and 13, which, with the partition-plate 10, are united together, as by angle-pieces 1A and bolts 15. The partition-plate extends a suitable distanee beyond the outer wall of the steam-con densing chamber and is provided with an upturned edge 16, to which, is secured, as by rivets, a Water-tank wall 17, which may be reinforced at its upper edge by a heavy ring 18. The steam-condensing chamber is, of course, steam-tight and maybe provided with a coniadapt it as a spray-head. It is supplied from a pipe 22 through branch pipes 23 that communicate with a source of water-supply. (Not illustrated.) The branch pipes 23 are, through parts of their respective lengths, submerged in water that is contained Within the tank 17.

A cock 24 controlsthe supply of water from branch pipes through the pipe 22 to the sprayhead. The pipe 22 may be severed, as indicated at 25, for convenience of connection with the cap-union 26. The level of the water within the water-tank is regulated by an overflow-pipe 27. It entirely envelopes the side Walls of the steam-condensing chamber and is kept supplied with fresh cold water from any suitable source. (Not illustrated.)

The purpose of the employment of a watertauk is not only to provide for the cooling of the water supplied through the pipes 23, but also to reduce the temperature within the steam-condensing chamber. This chamber receives steam from a source of steam-supply (not illustrated) though a perforated annular exhaust-pipe 28, that is supported Within the chamber, as by sheet-iron hangers 29 on ,two sides and on a third side by a branch pipe 30, which, passing through the wall of the steam-chamber, by means of a steam-tight joint 31 of suitable construction communicates with a steam-pipe 32. A suitable twopart union 33, secured to the wall of the Water-tank, as by bolts 34, may be employed for uniting the pipe 32 to the branch pipe 30.

In the manufacture of ice itis-customary to employ condensed steam as the material from which to produce ice, and as a matter of economy to take the steam exhausted from the engine. In some types of ice-machines, however, a certain percentage of the condensed water used for making ice must be supplied direct from the boilers, because an insufficient quantity of steam is exhausted from the engine to supply the necessary amount of Water for making the ice. By my invention, however, I economize in the amount of'steam required by supplying to the steam-condensing chamber an additional quantity of Water in the form of a spray, the spray mingling with the steam supplied from the pipe 28 within the steam-condensing chamber and by the action of the heat of the chamber is evaporated, and is thus rendered as available for the purposes of ice manufacture as the water condensed from the steam itself would be. The water of condensation accumulates in the bottom of the steam-condensing chamber and is discharged through a pipe 35, slightly elevated above the bottom. or partition plate 10, entering the reboiler 2. The purpose of the reboiler is to totally exclude air from the water and is for that purpose provided at a proper level with an overflow-pipe 36, which is preferably provided with an tip-turned mouth 37, that is designed to receive the water from its upper level and to act as a skimmer, which carries away any of the impurities which may accumulate upon its surface. The overflowpipe is provided with a trap 38, that allows the outflow of water and air under pressure from within the reboiler,but excludes the inflow of air under outside atmospheric pressure. Heat may be supplied to the interior of the reboiler, as by a steam coil-pipe 89, located in the bottom of the reboiler and communicating, by means of a pipe 40, with a source of steam. (Not illustrated.) A suitable joint 41 may be employed for conducting the pipe 40 through the Wall of the reboiler and for supporting it therein.

In order to keep the trap 38 in good operative condition, it is desirable to preserve the level of the water within the reboiler practically on a level with the mouth 37. For this purpose I employ suitable automatic valve mechanism for preventing the outflow of water from the reboiler into the filter-chamber. .A simple form of mechanism for this purpose may consist of a valve-seat 43, that forms a discharge-port through the bottom of the reboiler into the filter-chamber. This valve-seat is normally closed by a valve 44, whose stem 45 carries upon its upper end at a proper level a metallic fioat 46. The stem may be sustained in the vertical position, as by a sleeve 47, supported by arms 48, for example.

Beneath the bottom 9 of the reboiler the fil-.

ter-chamber is filled with any suitable filtering material 50, and upon the upper surface thereof a perforated sheet 49, as of galvanized iron, may be employed to confine the filtering material within the filter-chamber.

51 indicates a discharge-orifice, and 52 a perforated protecting-cap, separating the filtering material from the discharge-orifice.

In practice pipe connections are provided for conveying the purified Water from the discharge-orifice 51 to the place where it is to be used; but this is not necessary to illustrate.

In operation, steam being supplied through the pipes 32 and 40 to the interior of the steam-condensing chamber and the reboiler, respectively, water is admitted through the spray-head 2O into the steamcondensing chamber and is there evaporated and condensed. Passing thence into the reboiler, it is heated to the boiling point by the steam from the pipe 39, and as it rises within the reboiler sufficiently high to open the valve 44 it escapes into the filter-chamber and, percolating through the filtering material 50, finds its exit through the discharge-orifice 51.

I do not confine myself to the details of construction herein shown and described, having merely suggested in many respects those forms which now appear to me to be preferable, and reserve the right to modify and vary the details of construction and arrangement of the same within the scope of my invention.

What I claim is-- 1. The combination with a filter chamber, a superimposed reboiler and superimposed steam condensing chamber communicating with a source of steam supply, the filter chamber, reboiler and steam condensing chamber communicating in consecutive order from the condensing chamber down, substantially as set forth.

2. The combination with a steam condensing chamber and steam supply pipe, of a reboiler and an over-flow trap communicating therewith, a filter chamber, and an interme+ diate, automatic valve mechanism, substantially as set forth.

3. The combination with a filter chamber, superimposed reboiler, and superimposed steam condensing chamber, of a water tank surrounding the same, a steam supply pipe communicating with the steam condensing chamber, a spray head within the steam condensing chamber, and a Water supply pipe communicating with the spray head through the water tank, substantially as and for the purpose specified.

4. The combination with legs, a filter chamber and a reboiler and means for uniting them, of a partition plate and a steam condensing chamber, and means for uniting it to the reboiler, all substantially as set forth.

5. The combination with a reboiler and a superimposed steam condensing chamber, of a partition plate extendingbeyond the flanges, means for securing the flanges and partition plate in a tight joint, and a water tank wall secured to the periphery of the partition plate partition plate adapted to be secured in a tight joint between the said flanges, and means for uniting the parts together, substantially as set forth.

In testimony of all which I have hereunto subscribed my name.
