AIR-HUMIDIFIER.

To all whom t may concern: l Be 1t known that we, CHRISTIAN BECKER and F RANK D. KLEINHEKSEL, citizens of the United States, residing at Holland, Michigan, have invented certain new and useful Improvements 1n Air-Humidifiers, of whlch "the following isg-aspecification.

This invention relates to an improvement in air humidifiers, for use 'inu combination 'with heating furnaces.

The main objects of this invention are: First, to provide an improved air humidifier especially adapted l,to be used in connection with a hot air furnaceand adapted to utilize a portion of the waste heat usually lost through the chimney, although the humidifier maybe used to'advantage in other systems.l Second, to provide an improved air humidifier having suitable operating 'damp- 1 ers wherein the humidity of the air arising in the furnace pipes' may be regulated as desired or the amount of humidity may be regulated, no matter how delivered. Third,

tion by the devices and means described in the following specification.

modifi-cation of our humidifier` showing the arrangement of the various parts, takenl on line 9-9 of Fig. X. Fig. X is a detail horii zontal section through the modified humidifierstructure, taken on line 10--10 of Fig. IX.

In the drawing, similar reference characters Arefer to similar parts throughout ,the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section .lines.

Our humidifier is adapted toY be used in .connection with the ordinary hot air. furnace consisting of the usual cast metal fire box 1, the radiator 2, f-rom which leads the smoke pipe 3,.having a check draft 4 therein.'

The furnace is covered by the usual side casing 5, ythe conical top casing 6, invertedv cone deflector 7 and the various hot air pipes 8 lead therefrom. i

Our humidifier is adapted to be connected to the smoke pipe 3 between the furngce casing 5 and the check damper 4, as shown in Fig. I, whereby the products of combustion from the yfurnace will have to pass through the said humidifier lto heat and evaporate the water contained therein.

Referring to Fig. II, our humidifier con? sists of an -outer casing 9 and an inner casing 10 between. which casings is the heating flue space 11. On the lower side of casing 9 is an opening 12 embraced by the pipe 13 secured to said casing 9 and having the damper 14 therein. The spacesk betweenthe inner and outer casings are covered at their ends by theplates 15, see Figs. III and VIII, which are also provided with suitable central pipe fianges 16 to' connect the humidifier to the divided smoke pipe 3. The general shape ofv the casings are shown in Fig. II where the top of the same is wider than the casing body to facilitate evaporation.

Within the top of casing 10 is secured the water evaporating pan 17. The bottom of this pan is formed of a series of V-.shaped longitudinal corrugations 18, thus g1v1ng a greater area of heating surface to the said pan to absorb the heat from the passing products of combustion. At the furnace end of said pan, the bottom of the same is formed into a transversely disposed rectangular header channel portion 18, see Fig. VIII, in which terminates one end of the said V- shaped corrugations.

The to of our humidifier is adapted to inclose and) cover casing 9 and preferably is raised at the center. rlhe humidifier top is double walled, comprising

plates

19 and 20 between which is a suitable heat insulator 21, preferably asbestos wool. The said

plates

19 and 20 have a. depending outer fiange 22 which is adapted to engage and tightly cover the top of casing 9. A discharge pipe 23 is suitably secured to the said plates by the collar 24. Pipe 23 is led from the humidifier through the furnace top casing 6 and discharges centrally against the cone deflector 7, as shown` in Fig. I. Within the said discharge pipe is located a suitable damper 25. An opening 45 is provided to deliver from flue space 11 into the humidifying chamber above the pan.

From one side of the top of the humidifier extends the sheet metal hood 26, see Fig. VII, which is adapted to partially surround the smoke pipe 3, and has its bottom left open. Within the said hood is pivoted the damper 27 having the damper arm 28 secured thereto. Damper means 25 and said arm 28 are connected to be operated by chains or

cords

29, 29. The upper portion of the side wall of thecasing 10 is left open at 30 so asto permit heated air to enter the humidifier from the said hood, which will, of course, regulate the humidity. The quantity of air admitted to the humidifier may thus be regulated by the dampers 14 or 27 and the passage'of humidified air may be regulated by damper 25.

' Awafer tank 31 having a suitable cover 32 thereon is secured by the straps 33 to .the said casing 9. Water pan 17 and tank 3l are connected by the nipple 34, a water tight connection between the two being made by suitable nuts and washers, as shown in Fig. II. From the bottom of tank 31 leads a supply pipe 35. Said pipe 35 is shaped as shown in Fig. III, the samepassing-through the end plates 15, then forming a bend 35 toward the furnace inside of casing 10. This bend is connected to the water pan by the

vertical pipes

36 and 37, see Figs. III and IV, pipe 36 connecting the water pan at the center thereof while pipe 37 connects the same at the header channel portion 18 thereof. A suitable drain cock 38 is installed'in pipe 35 so as to drain the water pan and tank when desired. Water is ad? mitted to said tank 31 by the fioat controlled valve 39, which is controlled by fioat 42, Figs. I and II, which connects to the outside water circuit by pipe 40 controlled by valve 41. `The level of water to be maintained in the water pan is shown in Fig. II, where the same is slightly below the nipple 34, fioat 42 being so set to maintain this' level. To facilitate the removal of pipe 35 and pan 17, plate 15 is slotted at 43, the edges of which are bent and permits the slide plate 44 to open and. close the same, see Fig. VI.

It will be observed that when the furnace is in operation and water has been admitted to our humidifier, the waste products' of combustion will pass into the chamber formed by the casing 10 and heat-the water in the sald water pan 17. The vapor thus generated will rise up through the discharge pipe 23 into the furnace casing against the mix with the hot air from the furnace and thence pass up through the furnace pipes 8. The degree of humidity produced may be regulated by the damper 14 in the pipe 13, wherein outside air will be drawn through the said pipe and into the fiue space 11 and will thenmix with the vapors. The said fiue space therefore serves to heat this air and. thereby prevents any condensation of the said vapors. The amount of vapor rising in the said pipe 23 is regulated by the damper 25 therein.

The circulation from the supply tank 31 is through piipe 35 which connects to the horizontally sposed loop 35 disposed in the furnace end of the casing and smoke pipe. This is slightly inclined and connected to and delivers upwardly through pipe 37, and the circulation is induced by the heating of the loop 35 which takes water from the header channel 18' and circulates it downwardly and then upwardly to the pipe 36, sol that the water at the highest temperature delivers out through the vertical pipe 36 and spreads into the pan at the highest ont, and evaporation is thus greatly facilltated.

The connection we hswe indicated is much to be preferred, but very good results may be obtained by making the connections as appear in Fig. VIII, permitting the supply pipe 35 to deliver upwardly through plpe 36 into the pan and provide an independent circulating pipe system comprising the downwardly-extending pipe 37 from the bottom of the header channel 18', thence looping toward the `furnace horizontally and upwardly at 35" and rdelivering out at the cone defiector 7. Thehumidified air will` the supply tank 31'-, and When the hot water flows through at that point the colder water in the tank 31 will be displaced and be supplied into the vaporizing pan through pipes The quantity of dry air admitted into the humidifying chamber for circulation is controlled by the dampers 14 and 27 already described.,--\Vhere our humidifier is used with other heating apparatus than a hot air furnace, a pipe can deliver directly up from the top of the same to any apartment to be humidiied, as indicated by dotted lines in Fig. I.

kIn Figs. IX and. X We show amodiication of our improved humidifier, in which in place of the corrugated pan 18 We corrugate a section of pipe at 50, and surround the same with a casingl which forms an annular Water chamber 52, see Fig. IX. The heated -products of combustion circulating within the same passes into the corrugations y of the pipe 50 and heats the surrounding Water. The tank 31, pipe 35 and loop 35 are identical with those illustrated yin the preferred form,l the .loop 35 connecting to an upwardly extending pipe section 60 delivering into the top of' the annular reservoir, as seen in Figs. IX and X. This structure is suspended by the bands 54, as distinguished from the supporting rods 40', 4:0 of the preferred structure. able to insulate casing 51 by a suitable heat insulator 534 held thereto by bands 54. The top has an inturned iange 22 to fit the vaporizer tank.
