This invention rebates to improvcmcius in still will suffice. The generator 1 comprises \vucr stills and more lullllttllllll) to an irru. hollow body which, in the present illusproved construction of condenser for such a -truted embodiment of the invention is of still undmcuns for supplying cooling water rectangular form and comprises-surrounding thereto and one of the objects of the prrswalls 5 and other walls 6 which are spaced out invention is to provide a condenser inwardly from the walls 5 and connected constructed as to insure of rapid-21nd ecotherewith by a bottom 7, forming a preheatuoniicul condensation of the water vapors ing chamber 8 into which water is introwith a minimum waste of water for cooling duced by a supply pipe 9 provided at its top purposes and which condenser. will present wvith a funnel 10, the purpose of which will he presently explained. A bottom wall 11 is arranged within the bounds of the. walls (5 and defines, in conjunction with the upper portions of said walls 6, a enerator chamber indicated by the numera 12, the walls 6 having openings 13, formed therein to provide for the passage. of preheated water from the ireheuting chamber 8 into the gen eruting chumber 12, whereby a constant shallow level of water is maintained upon the bottom ll and rapidly converted into steum, the apparatus being, of course, arranged with thcopen bottom of the generator above a sourccof heat as, for exumplc, a cooking range. A plule 14-- is arranged within the generator to rest upon the upper-edges of the wells 6 and is formed with perforations 15 u d 16 located respectively .above and communicating with the preheating chamber 8 and generating chamber 12, so that the steam generated in these chambers and especially in the chamber-12, may pass upwardly through the open top of the generator.

The receiver 2 comprises a hollow rectangulcir body 17 provided in its upper portion with 1:. receiving pun 18 having a number of short nipples or spouts 19 extending upwardly Ewni its surface and establishing comnmnicelion between the spaces above and below the pun .A Will-("1' outlet pipe 20 leads from the lowermost portion of the pan, the pun beinginclined from all sides toward its mid-portiomand serves to carry off the distilled water. 'lhc body of the receiver is rcumvubly,disgaoscd upon the top of the body oi the generator. and the condenser 3 is, in turn, supported upon the top of the receiver.

The condenser 21 comprises a hollow rectangular body including surrounding walls indicated by the numeral 21, the body being disposed at its open lower end to rest upon the opcn upper end of the receiver 2, as clcurly shown in Figure 1 of the drawings. Arranged within the body of the condenser 3 above thenipen lower end thereof is a b lotlic vapors to becondcnscd. usnaxinium pooling or condensing surface within a given space.

Another object of the invention is to so construct the condenser that obnoxious volutile impurities in the water ill be carried off so as not to contmninatc the dis ilate,

Another object of the invention is to so coiwtruct the inc-ens provided for supplying co. r water to the condenser that the wutcr wi 1 be initially introduced into the condenser at a point where its cooling effect will prove most effective and in such uuumcr that the exchange of heat will tulrc place in u way to insure of complete condensation of the water vapors or steam in the most e-fl'ectivc manner.

Another object of the invention is to provide, in connection with u'condenscr,-a novel construction of reservoir and means associated therewith for supplying cooling water to the cooling water chambers of the condenser.

The still embodying the invention conr ises, gcucrully speaking, a generator which is indirzdcd in ueucrul by the numeral 1, a receiver indicated in gcncrul by the numcrul .u, .i condenser iudiculcd in gcncrzil by the numeral 3, and in cooling water reservoir indicated in general by the numeral 4. 'l'hc grncrutor l and receiver 2 arcv of tho coir strucli n illustrated and described in urv ropcudinc application Scriul Nu. (Jul-5!. lilcd December 4. ill-33, and, consequently. u brief description of thcsc riuupoucnt pulls ol' the 22, which is formed at intervals throughout means to be presently described, and it wi l its area with parallel longitudinal slots 23 into which are fitted and secured, in a fluidtight manner, the open lower portions of condensation chambers indicated in general by the numeral 24. Each of these chambers.

comprises side walls 25, end walls 26, and a closed top 27, and the arrangement of the chambers is best illustrated in Figure 2 of the drawings, It will be observed by reference to this figure and Figure l of the drawings, that thechambers are spaced 'so that coolin water chambers 28 are provided between eac two adjacent ones of the chamhers 24, and that similar cooling water chambers 29 are provided between the side walls of the endmost ones of the series of chambers 24 and the corresponding side walls 21of the body of the condensen'the' end walls 26 of the chambers 24 being likewise spaced from the other side walls of the body of the condenser to provide cooling water chambers 30. Water isto be introduced into the "cooling water chambers b be evident at this point that steam rising through the nozzles 19 will enter the condensation chambers .24 and be condensed upon comin in contact with the cooled walls of the

chambers

28, 29 and 30 the condensate dripping onto the surface of the pan 18 of the receiver 2 and flowing 'out through the pipe 20. The tops 27 of the-condensation chambers 24 are spaced below the open top of the body of the condenser3, and vent pipes 31 are fitted at their lower ends into openings in the said tops. 27 of the condensatwo chambers and extend above the chamhers to a point spaced slightl below the up r edges of the walls 21 of t ie condenser bo y. These pipes, as best shown in Figure 4 of the drawings, are closed at their upper ends, as indicated by the numeralli32, exce t that in their sides, immediately below their upper extremities, they are formed with a circumferential series of openings indicated by the numeral 33, through which any obnoxious volatile impurities in the water or, more s ecifically the 'watervapprs enerated in t e generator, may pass t .roug portion of condenser body, these gases findin exit by way of aseries of openings 34 which are formed i'n'th'e walls 21 of the body of'the condenseri'n a plane above the plane occupied by the closed upper ends of the vent pipes 31, the said' openings '34 establishing communication between upper ortion of theinterior of the condenser ody and the atmosphere.

Water is supplied to the condenser from the reservoir 4 which comprises ahollow rectangular body including side walls 35, end walls 36, a closed top 37', and a bottom 38, the ieservoir being removably disposed the P1181? at'its lower side upon the upper ed es of the walls 21 of the body of the con enser 3. The bottom 38 of the reservoir 4 is preferably in the form of "a relatively thick metal late which, as best shown in Figure 3 of' t e drawings, is formed in its under side at suitable intervals, with threaded openings 39 which extend part way through the plate, the plate being further formed, centrally of each opening 39, with a smaller opening or vent 40 communicating with the opening 39 and o ening through the upper side of the said p ate. The arrangement of the

openings

39 and 40 is preferablysuch that one, two, or any other desired number of such openings 39 will be located directly above the open upper end of the cooling water chambers 28 and 29, as best illustrated in Figure 2, and a distributin pi is threaded at its upper end and tte into each 0 ning 39,'the upper extremity of the pipe a utting firmly against the upper wall of the respective opening and the connection of the pipes with theplate 3S comprising the bottom of'the reservoir 4, being in this manner firmly established. Itwill be observed by reference to Figure 3, that-the openings 40 are of considerably less diameter than the openings 39 and the bores of the respective pipes 41, so that, byreason of this construction, no sediment or 'particles of foreign matter can enter the pipes ll which would be of a size to clog the pipes. Anotheradvantage-resulting from this peculiar manner 0 connecting the pipes with the bottom plate 38 is that there is no possibility of the upper ends of the pipes 41 projecting above the surface of the plate so that thesaid surface of the-plat'e is left entirely smooth, therebyproviding for an equal (llStllblltlOfl'Of water to all the pipes. and preventingthe accumulation of sediment or foreign matter.

A water supply pipe 42 is fitted at through one of the side Wal s 21 of the con n the top of the condenser 3 denser body and has its inner end turned 7.

downwardly, as at 44, and this pipe leads to any suitable-point of discharge as, for example, a kitchen sink, and manually adjustable out-0d or reljulating

valves

45 and 46 are arranged in the pipes 42 and 43 respectively, so that the supply of water to the reservoir 4 and the discharge of water through the outlet pipe 43 may be proper- 1y regulated to maintain the proper water level within the condenser. At this point,

it will be evident that cooling water is continuously supplied to the condenser and permitted to overflow from the same after it has served its purpor'e and that the water is upplied to the cooling water chambers at their portions which are subjected to the highest degree of temperature, the water initially supplied being. or course, at a lo\v er temperature than the water overflowing from the condenser. "Therefore, the walls of the condensation chambers 24 are equably cooled to correspond to the temperature variations prevailing over ditl'erent portions of their areas.

As in my previously mentioned co-pcnding application, a second overflow pipe 47 is led from the side of the condenser body 8 with its lower end entering the mouth of the tunnel ltl,-and a cut-oil valve 49 is interposed in this pipe and may be adjusted to permitof a regulated flow of Water through the said pipe 41' to the funnel 10 and from the tunnel through the pipe 9 to the preheating chamber 8. As the water in the condenser is heated throug i the exchange of heat between it and the walls of the condensation chambers. and rises to the overflow, this partially heated water is delivered to the preheating chamber, thereby effecting an economy in fuel.

In the wings, the apparatus is illustrated as of general rectangular form but it will be readily understood that it may be of cylindrical form and that the coin densation chambers and water cooling chambers may he made annular or cylindrical. as this general idea is embraced in my ctr-pending a 'iplication Serial No. 678.45%), filed December 4, 19:33, and it is obvious that the water reservoir of the pres-.rnt application might be employed in connection with the condenser of the said (a pending application with the necessarymodification.
