HUMIDIFYING DEVICE Filed Nov. 28, 1930 INVENTOR ZEEEET 3 c/OYDfl/Y BY w mug ATTOR N EYS Patented Sept. 6 1932 PATENT OFFICE LEIBEBT E. lrommn, or MINNEAPOLIS, mascara mmmrrrms DEVICE Application filed November 28, 1930. Serial No. 498,629.

This invention relates to an auxiliary heater and an auxiliary humidifyiug device adapted to be used in connection with a furnace. While the device is applicable for use with various types of furnaces, itparticularly is designed for use in connection with an oil burning furnace. There is often insuflicient radiating surface to properly-use the heat generated in an oil burner, and undesirable stack temperatures often result. It is desirable to have the airsupplied to living rooms at a certain degree of humidity, and the importance of this is emphasized today by heating engineers. It is an object of this invention to provide a simple and eflicient device for receiving the products of combustion from a furnace, using the heat thereof to heat air which is supplied to living rooms and at the same time supply humidity to said air. I

i It is another object of the invention to provide a device comprising a casing containing a water pan or receptacle, means for direct ing air over the water means for heating said 2 air from the products of combustion of the furnace, said device having a chamber into which said air is delivered, and from which conduits lead to the rooms to be supplied with heated air.

It is more specifically an object of the in vention to provide a device comprising a casing, a water container in said casing,'a plurality of spaced conduits having 0 n ends one of whichis disposed adjacent t e water in said container, said conduits communicating with a common chamber in said casing, a pair of conduits communicating with sald device at-opposite sides, and adapted to be connected respectively to the smoke pipe of a furnace and to the chimney, the gases passing through said last mentioned conduits passing around said water container to heat.

the water therein and the air passing through said first mentioned conduits.

These and other objects and advantages of the invention will be fully set forth in the following description made in connection with the accompanying drawing, in which like'reference characters refer to similar parts throughout the several views, which Fig. 1 is aperspective view of the device, certain parts being broken away to show the interior thereof;

Figure 3 is a horizontal section taken on line 33 of Fig.2; and

Fig. 4 is a vertical section taken on line 4-4 of Fig. 3. Y

Referring to the drawing, a device is shown comprising a casing 10. While this casing might be made of various forms, in the em bodiment of the invention illustrated it is shown as of rectangular form and elongated.

A conduit 11 communicates with the bottom 55 of casing 10 centrally thereof, said conduit having a flan e 11a secured to the bottom of casing 10. asing 10 has a pair of spaced partitions 10a secured to its ends, the same shown as having out-turned flanges at their ends secured to the ends of casing 10. These partitions 10a are connected at their bottom by a plate 100, the plates 10a and 100 thus forming three sides of a rectangular casing, and the plate 106 extends between plates 10a a short distance below their top edges, this plate extending to the ends of casing 10. A

rectangular casing 12 extends downward from the central portion of plate 106, said casing 12 being adapted to form a water receptacle, and the water may also be contained in the pan formed between the plates or partitions 10a and the ends of casing 10, the water being represented in Fig. 4 as 12a. The plates 10a, 10b and 100 form a rectangular casing disposed within casing 10. It is desired to maintain a certain level of water in casing 12 and the pan thereabove. While a suitable means may be used for maintaining such level, in the'embodiment of the invention illustrated a float 13 is used, secured to a lever 14 pivoted at 16 to a valve and bracket 17 secured to a pipe 18 extending through the end of casing 12 and through the end of casing 10. This pipe will be secured to the end of casing 10 by a suitable coupling 19. A motor 20 illustrated as of the electrical type is mounted upon a suitable supporting means such as the legs 21, which will rest upon the floor or other supporting surface.

v vertically extending passages 24 between the dMotor2O has a fan 22 secured its shaft which is located axially below theconduit l1 asshown in Fig. 2. a The partitions 100 form 1 through an opening in the plate 10a to which it is secured. Casing 12 has a conduit 12?) extending between its sides, said' conduit being axially alined with the conduits 2'1 and 28 and being controlled by a damper member 25 secured to a rod 25a having a crank on its end which in turn is pivotally secured to a. handle rod 26 extending through a tube 264 secured in one plate 10a and one side of the casing 10. Rod 26 has a ring 266 at its outer end and tube 26ais provided with a packing nut 260 at its outer end. It will be seen that damper 25 can be regulated by the rod 26. The conduit 27 is adapteddso be connected to the smoke pipe 29a of a furnace 29 and the conduit 28 is adapted to be connected to a. chimney 30. A conduit 31 has an out-turned flange 31a secured to the top of casing 10 and communicates with the 1n-.

tcrior of the casin 10 through an opemng in the top thereo conduit 31 preferably being'axially alined with conduit 11. .7

i In operation the conduit 31 will extend to one or more rooms to be heated, and motor20 will be driven. Air will be forced into conduit 11 and this air will be deflected by the plate 100 and will pass around the partitions 10a and into the chamber at the topof casing 10 over the water in the pan at the top of casing 12 and out through the conduit 31 as .indicated by thelarrows 32, The hot prod nets of combustion from furnace 29 will pass through'conduit27 and the same will pass around the bottom and ends of casing 12 as indicated bythe arrows 32 and will then pass out through conduit-28 to the chimney. The casing 12 will be heated as will the water therein, and the plates 10a and 100 will also be heated. Part of the water will be evaporated and will pass out with the air passing through conduit 31. This evaporation will be assisted by the air passing up around the plates 10a and over the top of thewater, so that the air passing out through conduit 31 is well humidified. The air passing in through conduit 11 will also beheated byits passage around the plates 10c and 10a so that warm humidified air is supplied to the rooms through conduit 31. The desired level of water will be maintained by the float 13 regulating the valve 17. If a stronger or more direct draft is desired through the device, the damper 25 can be opened by manipulating the operating rod 26; If this is done, the products of combustion can pass directly through the conduit 12?) and will not have to pass around casing 12. The damper 25 will normally be closed.

From the above description it is seen that applicant has provided a very simple heating and humidifying device. The excess heat in the products of combustion from the furnace is utilized tovheat the air which is delivered to the rooms to be heated, and to evaporate water to supply the desired humidity- The apparatus is quite efiicient, as it uses only heat which would otherwise pass into the chimney and be lost. The device is simple in construction, can be inexpensively made and installed, and results in quite a saving of fuel. The device has been amply demonstrated in actual practice and found to be very successful and eflicient.
