Formed-on the boiler 2, adjacent the bottom thereof; is a nipple 7 which extendsthroughan opening I, 8 in the mantle 6 and'tothe outer endof which is connected 2 a water conducting; line 9, such as ahose. The hose 9 leads from asupzply tank 10 ,whichis conveniently located with respect tothe boiler and frompwhich water is passed through the hose 9' and nipple '7 to tlieinterior of the'boiler2'.

The open upper end of thefboilerfisiprovided with. a cover 11 which is'formed an'annula r, downturned flange 12'which 'depends into .a trough 13 formed e'xteriorly of the boiler adjacent the upper end thereof by meansof an angular flange 14. Seated on the cover 11 is" an insulating member 15,fupon which is seated 'a receptacle 1 16 which is .1 formed with a vertical, annular partition 17 76 whereby the interior "of the receptacle :16ifis divided intoan inner compartment 18 and an outer-compartment 19. Opening'through the cover 11 is a tube 20 which extendsupwardly from the cover throughthe insulating 'ele- 7 5 ment15'and-receptacle16.

' The partition 17 is of materially greater height than the outer wall 21 of the receptacle 16 andseated on the upper edge ofthe p'artitiont17is'the bottom 22ofa receptacle 23 which is of materially smaller diameter than the receptacle 16 and whichi's arran'ged concentrically .withfrespect theretoQ Formed on thereceptacle 23 is a downturnedannular flange 24 which dependsint'olthe outer compartment 19 ofithe receptacle16..f Q Extending through the bottom 22 of the receptacle 23 is a condenser 25' which is of elongated formation and which islforrned with'a closed upper end and an open lower end. The lower end isf'arranged in spaced relation to the bottom 26 of the receptacle 16 anddepends a substantial distance below the upper end of the tube'20 which is arranged concentrically with respect to the condenser 25. A, suitable packing 27 is interposedjbetween the wall of the condenser" 25 and the wall of the opening in the bottom; 22of the receptacle 23 through which the condenser25 extends order to provide a' water-tight joint between the receptacle 23 and condenser; 25. The upper portion of the condenser 25 is substantially star-shaped in cross section and tacle 23. Leadingintothe open upperiend ofi the tank 28 is a supply pipe 30, which is adapted to be connected with any suitable source of water supply for the purposeof conducting water to the'interiorof the tank 28. 7

Connecting theouter coinpartment19 of whatever height it is desired to water level in the boiler.

the'receptacleltlwith the trough 13 is a pi e .311 and connecting the trough with t e supply tank 10 is a pipe 32. The supply tank 10 is provided with an overflow pipe 33 by :meansof which the water in the boiler 2 may be maintained ataconstant level during the operation 'of'the apparatus. It is contemplated that the .pipe 33 will be positioned at maintain the 7 The pipe 32-opensintothe trough. 13 adj acent the upper edge thereof order to maintainja *quantity'of water innthe trough 13 constaritlyjby means of which the joint between the flange. 12 of the cover 11 and the I wall of the trough is effectively sealed. The

pipe 31.opens into the outer compartment 19 adjacent theupper edge thereofwhereby a.

quantity of water is constantly, ,maintained Jvithin the'compartment 19; to seal the joint .hetween'the flange 24 of the receptacle 23 and the bottom wall ofthe compartment 19. The opening. of the pipe31 intothe compartment 19 is materially lower than the upper; edge of the partition 17 whereby the level of the water within the compartment 19 is maintained a material distance below the upper edge of the partition 17. An outlet 34 is providedfor theinner compartment and insertedinto' the outlet 34 is a discharge pipe 35 which is formed with'agoosefneck 36;

. i In the operation ofmy distilling apparatus, water issuppliedfrom the supply tank 10,thr0ugh the hose. 9 and nipple 7 to the boiler 2. The waterwithin the boileris heat- -.ed.by means of the burner 4- and the steam generated from' ,suchYheatingl is passed through the tube 20, into the condenser 25.

' During the operation of the apparatus, water iscontinually passed through the pipe 30 into ,the'cooling tank 28 andfdue to the contact of such water with thewall ofthe condenser 25,-

the steam within the latter is condensed and fpassesfthrough the open loWer'end. of the ,condenser intothe inner compartment 18 of the receptacle 16: 1 From the compartment 18, the pure water may be drawn off. through "the discharge pipe 35. Owing to the constantoverflows from the coolingtank-55 to the Owingto'the arrangement of the pipes 31 Sand 32,- the overflowiwater'. from the cooling tank 28 in its passage to the supply tank 10 constantly maintains a supply of'water within the trough 13andouter compartment 19 as heretofore mentioned. The discharge pipe 35 is rotatable with respect. to the outlet 34 whereby the goose neck 36 may be positioned to extend upwardly asshow'n in Figuregl, or may be positioned otherwise if desired.

a Inthe embodiment shown in Figure 5,;the

boiler40lis provided adacentitsopen upper end with external threads for engagement with a threaded flange 41*which depends downwardly from the cover 42} for closing the upper end of the boiler. Thecover 42 is formed centrally thereof with an upstanding, substantially conical boss 43 which is provided on its upper face with an upstaind; ing, annular flange 44. v Spa'ced gfrom the flange44 i1theboss 43 is formed with a shoulder 45., t ereby providing in the upperface i of the boss-43, a groove 46. From the shoulder 45 the .upperfface oftheboss 43 slopes downwardly and inwardly forming, a cup 47'.

Opening through the cover 42 and extending upwardly through the, boss 43 is a tube 48 which projects upwardly from the cup 47, concentrically of-the latter. Disposed with.- in the groove 46 is the annular lower end of a condenser49, the-upper portion of which is constructed in the same manner as the condenser 25 described in connection withFigures l to 4; The lower end ofthe condenser 49 bears against the inner face of the flange 44 and is seated on a packin ring 50 disposed f within the groove46 where y a tight-jointis provided between the condenser 49 and boss 43. i

Seated on-the cover 42 is a pairof-insulating elements 51 the inner edges of which conform in contour to the outer surface ofthe boss 43. ,Seated on the member 51 is a receptacle 52, theinner annular wall 53 of which fits tightly against the outer face of the flange 44. supportedon brackets54 extending .up-

wardly from the receptacle '52 is a cooling tank 55, the construction ofwhich is similar to that of the cooling tank 28 described in connection with the form shown inFigures In the operationof the apparatus, water receptacle 52, from where it is passed through a .pipe 56 tothe supply tank 10.

t nd ng mamDetainee members 51 and through the wall of the boss 43 is a discharge pipe 57 the inner end of which opens into the cup 4:7. The discharge pipe 57 extends downwardly for connection with a receiver 58 for the pure water drawn from the cup 47 and is provided adjacent its lower end with a trap 59. The receiver 58 is provided with a faucet 60 which is disposed above the horizontal plane of the outlet for the pipe 57 in order thatthe level of the water within the receiver 58 may be maintained above the outlet for the discharge pipe 57 Adjacent the bottom thereof, the receiver 58 is provided with a drain 61 which is located below the'horizontal plane of the outlet for the discharge pipe 57. The formation of the cooling tank as show in Figure 2 is designed toprovide greater area for air contact than would be provided by a cylindrical cooling tank, which more rapidly expels any possible heat which may have been absorbed by the water in cooling tank from the vapor collecting in the condenser. The periphery of the cooling tank is, in the formation indicated, intended to provide a more extended surface for contact with the atmosphere. The periphery of the condenser, in the formation shown, is intended to provide a more extended surface for contact with the invention will be readilyia'pparent, and although the preferred embodiments of the inill vention are as illustrated and described, it is to be understood that various changes in the details of construction may be resorted to, so long as such changes fall within the scope of the invention as defined in the appended claims. 7
