However, The relationship of the various parts is such it will be understood that the invention is not that the sections may be assembled and suplimited to the details disclosed but includes all ported one on the other in stacked relation. Fursuch variations and modifications as fall within ther, owing to the structure described a humidi 55 er including the desired number of these sections may be conveniently mounted in a stack between the adjacent ends of sections of the stack the humidier when thus mounted forming a portion of the length of the stack. In assembling the humidifier between the adjacent ends of the sections 22 and 23 of the stack the lower section 10 of the humidier is mounted on the upper end portion of the lower stack section 22. The relationship'iis'such that the upper end'of stackxpiece or section 22 engages the lower outershoulder 21 of humidier section 10 and the upper end portion of said stack section is embraced by the pore. tion of inner wall 15 below said shoulder 21.. VvThis is as clearly shown in Fig. 3,
Next, the humidifier section 11.isstolbe:a'dded and it is simply disposed on the section 10 with its bead or rib 17 arranged'` at* the inner sides" of the upstanding projections or lugs 18 0L section? 10 and with its shoulder 21 resting on the upper edge-offtheinner wall 1`5fof 'section 10E The upper end portion'of this inner wall of-'sectioni lOlis-embraced by that portion of the=innerI wall of section'fll belowtheshoulder v21 ofsai'd section 1l.

With this arrangement it willbe-notedthat each added humidiiier' section i'sfsupport-ed'? by the previously mountedhumidiiier section and? that thevarious sections#ofthehumidifier/'eachfornra port-ion of the stack into which they are introduced and that the upper' stack: section is supported againstl the lastaddedihumidi'er section. v

The-heat will1 of course, bel transmitted tothewater i'n' the A various sections or receptacles with-l tl 1e'resultL that theewater 'will be rapidly evaporated thus adding considerable moisturetoth'e atmosphere.
The various? sections orA receptacles 10 lthrough 131may'be' divided into` compartments 2o'i as4 by mea-nsof radiallyextending'walls or ribs 25 ex'- tending between the inner andiouter wallsl 15 and 1'6 of the' sections'. The'sedividi'ng orpartitioning walls 25 lwill', of" course; corrduct heat from' the inner waiisiof'f .thereceptacleto the water in' the receptacle thereby further' heating the' waterf'to increase evaporation. In its bottom wall 14 in each of its compartments 26 each humidifier section (with the exception of the irst or bottom humidifier section 10) is provided with an opening 27 which may be elongated as shown and about each such opening there is provided an upstanding flange or wall 28 each such ange or wall being somewhat greater in height than are the partitioning or dividing walls 25 forming the compartm'ents.
The openings- 2'7l together with the upstanding flanges or walls 28 provide overflows, the function of which will later more fully appear. Here,
however, it is pointed out that while such walls kwalls ofthe'various sections l0 through 13. Certain of-th'efradially extending partitioning Walls 25 may be provided with enlargements 29 having openings therethrough for thepassage of bolts.
Also; enlargements 30 maybe' formed between thefinner'wa'llsl of the various sections andi the various up'st'anding flanges or' walls 28 forming the overiiows. TheseA` latter enlargements 30'are also provided with vertical openings andl when the various sections are assembled. to form the humidifier certain of the openings are brought intore'gi'stry and bolts 31 may be passed through them andi the nuts on the ends of such bolts may be tightened to draw the sections against oneanother'and secure them intheir proper assembled relationship; When the sectionsare assembled they are so=arranged relatively that the openings??Y in the bottom of each section is out of registryf'with the openings in the bottom wall ofthe next adjacent section.
They watersupply means includes a housing havingaA thickened wall portion 33 provided with a relativelyf'srna'llwater inlet openingr 34 and va valve 35'arranged'when seated-'toclose said water' inlet; A supply pipe V36- connected with any suitable source' of supply is arranged to deliver water tothe smallinlet or passage 34 and when the"valve-35 is off? itsV seat water from the supply pipe36fpasses` to a pipe or tube 37 which has its upper end portion connected with an L-tting 37a extending through the outer wall of the uppermosthumider section whereby todischarge water into such humidierlsection.
As the water Ain the upper humidifier section 13A reaches the upper end ofthe overflows represented-:by the openings 27' andthe tubular walls 28, the water passes downwardly through such overflows andiinto the next lower humidier'section, which' in the drawings is the section 12. The overflow' openings in section 12 are as above stated out of.` registry with the overow openings of section. l3` and the section 12 will therefore iill. When the water reaches the proper level in'.sectionzlfadditional watersupplied to the section Will overflow through the tubular walls 28 of: saidY section andpass to the next lowermost section or'to the ysection 11 as shown in the drawings.
On section 11 becoming sufciently lled the water overflows to the bottom section 10 and this .section through a fitting or nipple 38 communicates with the float chamber of the housing 32 as clearly shown in Fig. 3. When the water in section 10 reaches the desired predetermined level it Willhave reached this same level in the float chamber of housing 32 with the result that thefloat 39 in said chamber will be lifted to seat the-'valve-B'and"therebycut off the further supply of the-water; (Nipple 38 communicates direct'-, 1y withbut one ofthe compartmentszdofgthe lower section 10 and `this compartment is designated 26a and as clearlyr shown in Fig. 5 isprovided with a seriesof radially extendingns 40 formed with the inner walls.15 ofthe section.
- These ns 40 will. serve to conduct heat from the inner wall of section 10 outwardly'into the compartment 26a of said section. Thus thewater in this particular compartment will be evaporated more rapidly than will the water in the other compartments and as soon as the level of the water descends, float 39 willv drop andvalve 35 will be raised off its seat whereby vadditional water will be supplied to the uppermost section or receptacle. The water will Loverow from ,one section to the next as abovedescribed until the water in compartment 26a reaches the desired level when the valve will againbe seated;
From the foregoing it will be .understood that the water in the compartment 26awill by its level control the opening and closingof thevalve 35; 'I'his is true since such compartment is in communication with the float chamber through the nipple or fitting 38 and an increased evaporation or the more rapid rate of evaporation is provided for by the fins 4U. Of course, it will be understood that fins corresponding with the fins 40 may, if desired, be provided in each ofthe compartments of each section. In the event this is done thenV a greater'number of fins should be provided in the compartment 26a since toinsure a supply of water in all of thesections the water should preferably be evaporated more rapidly from the control compartment. l It will also be `noted that these additional iins are necessary in this particular compartment since there is an increased supply of water` to be'acted on, this increased supply being represented-by .the water int the float chamber.
The housing 32 may'have its upper wall 41 removably securedsin place as by screws' 42 and in its lower or bottom wall it may be` provided with a clean-out opening 43 normally closed as by a plug44. The overflows of the various sections' in addition to providing means whereby a lower section is lled'by water Aoverflowing from an upper section, also provides` for the circulation of` air from one section to the next. Of course, the openings 19 in the upper edge portions of the outer walls of the section provide for the circulation of air between thesections andr over their open upper sides. Air may also circulate upwardly through the .overflow openings. It is furtherto be understood .that vif desired the bottom Vor initial `section of the humidifier'may be of the same construction as the upper sections. That is, it may be provided with an overow and in such instance the iioat chamber would'be so arranged that the oatwould operate to close the control `valve .and shut off the supply of water before the waternin the lower section reached overflow level. 1 l
Figs. 6, 7 and' 8 show various installations of the improved humidifier. In Fi'g.' 6 a boiler; or furnace is indicated at 45 and is provided cen-` trally with a stack 46 between the adjacent ends of adjacent sections of which the improved humidier may be inserted as generally suggested at 47. In Fig. 7 the furnace or boiler isdesighated '48 and has a stack connected with its rear side, the stack including a short rearwardly 'ex. tending section 49 and a vertically extending section 50 in which is mounted the humidifier gener` ally indicated at 51.5' The boiler or furnace ofl Figi, 8 is generally .designated 52 and hasconnected with it a horizontally extending stack portion, 53.into-which may be introduced a T-iitting 54 `on thevertically extending stem portion of which the humidifier may be mounted as at 55. With this kconstruction a suitableibaiile 56-may be introduced to deflect the hot gases upwardly into the humidifier and to prevent the escape of such gases a `closure 57 may be applied to the upper end of thetting or to theupper end of the humidier. Y l
In Fig. 9 the humidier generally designated 58 and including the sections 10, 1l, 12 and 13 vis shownvas enclosedvin a casing 59 which may be of sheet metal or the like and the upper side or top of the casing isclosed as by one of the cover members 57.shown in,Fig..8. Conduits 60 and` 6.1 communicatev with the interior of the casing 59 and the conduits 60 may be used for supplyingy 10 is provided about its upper edge with an in- 5 clined annular flange or lip 63 whereby any condensation formingon the interior of the casing 59 will drain into` the lowerA humidifier section. Further, each humidifier section, when encased as in Fig. 9, may on its outer surface be pro- 5..
vided with ribs or fins 64 to absorb and conduct heat to the water of the section, when heated airy isblown into the casing. l y f It will now be `understood thatvthe humidifier asY installed includes a greater or lesser number of sections or units depending o n the size of the buildings to be treated. On this basis once the device is installed there is no occasion for regulating it since the iioat 39 will operate the valve 35 to keepk the proper water level in each -of the sections of the, humidifier.` jWith the humidifier installed on a stackY in a basement of. a dwelling the moistened air will penetrate to all parts of the dwelling. When the humidifier is encased as in Fig. 9 a forced circulationof air through thehumidifier Awill provide air of the desired humidity to a relatively large structure. Assuggested in Figs. 6, "l and 8 the humidifier may be installed in a number of Ways and the invention is not limited to any precise manner of installing the humidifier or to a humidifier of any particular number of sections. As suggested above the lower section 10 of the humidier need not be structurally different from the other sections although it is preferred that the lower section have an imperforate bottom Wall.VV .The moisture given oli keepsthe floors of the building from drying out, and as this humidifier is placed on the smoke pipe from the heater it is very beneficial. Also,- the water absorbs considerable heat and gives it oif into the' dwelling, which represents a 'considerable saving as it is waste heat which would otherwisebe lost up the chimney.
