the water receptacle is filled to a point above the bottom of Athe clothes receptacle whereby the releasing device is immersed. When the water begins to 'boil it will follow the steam up the space between the tjworeceptacles, and said hot water/and steam Wijll,be projected through the; perforations onr to the clothesgf f Ther top of 4the' clothes receptacle is open' and thewater fromthe jets will accumulate' in the clothes receptacle.v -As the' water in the'water receptacleboils` krup" acertain pressure is exerted on the valve .or upon the end ofthe trap member` as the case maybe, and a sufiicien't amount of water Vmust Abe accumulated in the clothesA receptacle before this 'pressure-is overcome. EX- perience has shown that the 'said pressure Vwill be "overcome quicklyV 'andi-the water' in the; clothes' receptacle will v 'be Y instantly released, thereby causing .a sudden 'precipita- AtionfVNV j. y A l l1 'T heinventionj willbe more readilyunderstood from a reading of the followingspeci- -Vcationancl by reference to the accompany- `ingdrawings, in which .an v example vof the inventionA `is illustrated, and" whereinr',Figure 1 is a vertical'sectional view of an rapparatus constructed injaccordance/ with .this invention, Y-

"Theparts 17, 18 and V1 9 constitute a releasing device and, form a trap for holding water :in the 5 clothes receptacle until it is released.l The releasing ,de-

Vvice y permits of considerable variation in structure.

" In operating the wash' boiler water is placed in the receptacle 3 until it covers the bottom -15 of theclothes receptacle as .indicated by the water line. o Soap or otherwashing agents yis placed in the boiler and .the clothes to be washed `are vthendeposited in the receptacle 6. Heat is appliedunderfthe water receptacle and within the casing 1 and the water caused to boil and the soap dissolved. The water at the `lower end of the space`12 will boil first and a proportion of steam will be generated with theresult that said steam and water rise in the space 12 as "the boiling continues. The steamv and hot water willy first beprojectedfthrough the .perforations 14, but as the boiling increases thesteam and .water 'will rise in the space 12 projected throughthe perforations 13 with great intensity or force,v all of said jets converging toward the center ofthe clothes ,receptacle "and` formiiflsV Spray which acts lo'n the'clothes and spurts throughthe fabric ofthe same with considerzdile'force,v

A sthe Vwater boils av certain pressure will be exerted on the open end lof ktheelbow 19 andfthus no'water will p assfrom the clothes receptacle down" through thepartsl? and 1S until sufficient ,water has been accumu- 121t1 .ie the Clothes me'ptile119,0 Qvercqme vthe saidpressure. VWhen the pressure is overcome'and the waterfreleased the action iivltbeisuddn. Up. to the `time this relaas* ing action'takes place the jets Will continue and their intensity gradually increases; however the the water in the clothes receptacle 'is released `the jets cease and as .the water is precipitated or rushes from the yreceptacle 6 down through the parts 17 and beginsftoboil yup and is againfprojectedin jets. This action is again'followed-bythe releasing action and the yopera-tion continues as long'as'fthe heat is maintained and sutiicient water yremains f in the receptacles.

1 As stated the releasing device permits of y varied construction so long as afdepending pipe Aor tubular member is'us'ed and this invention contemplates the use of a depending pipeor tubular memberin all its l'forms'. As illustrating one of 'the variations a modified form "of-releasing deviceis show-n inFigs. 3 and 1. Allth'e parts are the same asin Figs 11and2 with theexception of `the 'omission ofthe partslS and 19. An elbow 20 is attachedto lthe lower end ofthe member 117, and the lateral end of the elbowterminatesin a flared mouth 21 covered ilpya screen 2 2 and containing a ball valve23.

Pressure .acting on the valve 2 3 seatsthe-sarne against the en'd of the elbow and'obstruets the downward flow of water through said elbow. Whenthe weight of the water -in `the clothes receptacle andy the parts Hand 20 is suiicient to overcome tlie`pressurethe ball is dislodged and rolls downl against the screen .,22, whereby the water iisY` released. lill-he vflaring mouth provides an area over which the pressure may actlaterally in seating the valve. y

The foregoing description and illustration clearly express the'invention, but itis to beunderstood .that said: illustrationpis merelyan exemplification and the invention may be carried yout in various other ways.

1. In a wash boilen' a water receptacle, a clothes receptacle mounted in the, waterv receptacle and having its bottom somel dis- Vtance above the bottom Vor the water recep-Z t'acle,y .whereby a water reservoir isr ro- ,vided below 'the clothes receptacle, the

clothes receptacle'being slightly's'pa ed l from they water receptacle;Y whereby 7 af vertical s' ace'is provided between'the receptaclesfap reservoir formed between the bottoms of the two receptacles.

2. In a wash boiler, a cylindrical water receptacle having an internal projection near its upper end, a supporting casing sur,- rounding the lower portion of the water receptacle, a gasket mounted on the projection within the upper end of the water receptacle, a cylindrical clothes receptacle having its upper ends resting on the gasket within the water receptacle, means mounted on the water receptacle for clamping the upper end ofthe clothes receptacle on the gasket whereby steam tight-joint is had, the clothes receptacle being slightly spaced from the water receptacle to form an annular vertical space therebetween closed by the steamtight joint at its upper end, the clothes receptacle having a' plurality of minute per- Eorations grouped together at the upper end of the space between the receptacles, an opening in the bottom of the clothes receptacle, and a tubular water holding and releasingkmember dependingvfrom the opening and having a laterally directed discharge opening below the bottom of the clothes receptacle. p

In testimony whereof I aHX my signature.
