eferring to the drawings, particularly Figs. 1 to 3, a device is shown comprising a heating element 10 in the form of a radiator. While any form of radiator might be used, in the embodiment of the invention illustrated, a radiator of the type having pipes conducting a heating medium and metal plates such as copper plates extending transversely thereof, is shown. Said radiator comprises the end members or headers 10a and 10?) between which extend the pipes 100 whi h pass through and support a multiplicity of transverse thin metal plates 1001. An inlet or supp y pipe 11 is connected to the header 10a, the same being equipped with a regulating valve 12. A discharge pipe 13 is shown connected to the header 1%, the same being equipped with a trap member 14:. A pipe or conduit 15 is provided connected at one end by the coupling 16 to the header 10a and connected at its other end to a T- member 20, connected to the top of the header 1%. A relief valve 21 is connected to the top of T-member 20. An aquastat or thermostat 17 of the so-called surface type is secured to conduit 15 adjacent T-member 20. Said member has projecting lugs at its ends about which and the pipe 15 pass the clips 19 securing member 1'? to said pipe. A connection 22 is screwed into the side of T-mernber 20 to which is connected a supply pipe 23 for liquid such as water, and this pipe passes through member 2i conduit 15. An elbow connection 2% is screwed into the fitting at the end of conduit 15 to which a connection pipe 220. is secured. Pipe 22a extends from member 24 to the strainer member 25, and another short pipe 22b forming a continuation of pipe 22a extends from strainer member 25 to a solenoid valve 25. A housing 2'? encloses the radiator 10 having a rear wall 27a, a front wall 271) and end Walls 27c extending between the walls 27a and 2%, said housing thus being substantially rectangular in horizontal cross section. Casing 27 has openings 27d at the bottom thereof forming air inlet openings and the front wall 272) is provided with a multiplicity of openings 27c forming outlet openings for air. Said front wall 2'21) has a depressed panel in which openings 276 are located and also a depressed panel below said panel, said panels being disposed between portions 27; and 275/. A member 27h extends about i the top of casing 2? also forming an ornamental bead and forming the top of said casing. Partitions 28 extend vertically between the front and rear walls 27a and 2712 some distance from the latter, said partitions extending from the top A of the housing 27 and having outwardly extending horizontal portions at their bottoms engaging the tops of the headers lea and 182) respectively. As shown in Fig. l, the partitions 28 form chambers at the ends of housing 27 in which are disposed the members 20, 21, 22, the strainer 25 and the fitting 16. A casing 30 is provided, disposed in housing 27 between partitions 28, said casing having a lower portion 30a extending longitudinally of housing 27 and radiator 10. While casing 30 might be variously formed, in the embodiment of the invention illustrated it is shown as tube-like or tubular in form. Portion 305: has an opening at its right hand end as seen in Fig. 1 and a nozzle 31 is connected to valve 26 in position to have a discharge aperture directed into and lengthwise of portion 30a centrally there of. Nozzle 31 is constructed and arranged to direct a fine spray or mist into portion 38a. Casing 3b is formed with a return bend. or reverse bend or elbow 30b and an upper portion 300 extends from portion 301) above portion 390! and thus longitudinally of the housing 27. The lower portion 30a inclines downwardly somewhat toward its left hand end as seen in l and a drain pipe 32 is connected to the 10*; est por ion of casing, the same extending through one partition 28 and downwardly through the bottom of housing 27. Portion 39c turns upwardly and has secured thereto an upwardly extending flaring portion 36d, the upper portion of which is quite elongated and in the shape of an elongated rectangle in horizontal cross section. A discharge portion or nozzle 306 extends from the top of portion 380? and as shown. Figs. 1, 2 and l 3, this portion extends laterally and has a discharge opening or slot of elongated and oom-- ing 30 has a pair of lugs 30h extending from its top adjacent portion 30d into which are secured the hooks 33. Bars as extend across casing 2'7 adjacent the top thereof having iianges engaging the sides 27a and 2% respectively and secured thereto by suitable bolts or rivets. Rolls 35 extend downwardly from the bars 34, said rods having eyelets at their upper ends through which pass the headed and nutted bolts 36 secured in the bars 341, said rods 35 also having eyelets at their lower ends into which hooks The portion 30a of casing 30 has a hook 3? secured in its top adjacent its open end and said hook ongages over a rod 38 extending between walls 2% and 27b and supported in lugs 38;: thereon. Casing 30 is thus supported so that it can be readily removed by disengagement of the hooks and 37.

In operation the pipe 22 will be connected to a source of water under pressure such the city mains. A heating medium will be supplied to radiator 10 through the pipe 11. The aquastat 17 will be electrically connected to the solenoid valve 26 so that when the temperature of the medium in conduit 15 is at a certain point, the valve 26 will open water will be projected from nozzle 31. Valve 26 also be controlled by thermostat or humidistat disposed in the rooms to be heated. his water will be projected in the form of very fine spray or mist longitudinally of the portion 0a of casing 30. The mist is projected preferably in the form of a cone having its apex at the nozzle and its base substantially at the wall or portion 380.. When the radiator is heated, the temperature within the casing 2'? and within the chamber between partitions 28 will be quite high and the air in said chamber will be heated as will also the casing 30. There will be a tendency for the air to rise through the casing 30 and the movement of the ir through said casing will be augmented by the spray from nozzle 31. The mist or liquid thus moving through the casing 30 will be thoroughly mixed with the air and tak n up thereby and the moisture laden air will pass to the top of casing 30 and be discharged through the opening in nozzle 30c. This air will pass through the openings 276 into the rooms to be treated. The air housing 27 between partitions 28 is heated by radiator 10 and the air thus rises and passes out through openings 27c, air entering through the bottom openings 27d. This air passing through the housing 2'! mingles with the moisture-laden air ng from the nozzle Bee and as stated, both pass out through the openings 27c. Any surplus moisture in the form of liquid will drop to the bottom of portion: 30a and 302) or will drain back to the portion 361) from the bottom of portion 300 and this moi"- ture will out through the Should any moisture collect on the walls of portions 39d and 306, will also drain back in the portion 300 and pass out through drain pipe 32. The bottom of portion 300 slo es downward V somewhat towards portion 30b. lip 3dr; at the end of the nozzle 30c will act somewhat as a baille to preven any moisture out at the lower edge of the discharge opening or dripping from said edge. When. the radiator 10 contains a heating this medium will pass in conduit 15. This temperature will actuate the aquastat 17 so that valve 26 will be operated to-supply water to nozzle 31 at the desired temperature. The water supplied by pipe 22 passes through strainer 25 where all solid matter will be removed. The movement of the air through casing 30 is thus caused both by the natural draft or the natural movement of the heated air upwardly and by the induction of the air caused by the spray from nozzle 31. The air passing out through the openings 276 is thus effectively humidified without any danger or" it carrying any excess moisture. By means of the temperature control it is assured that the liquid will not be sprayed by nozzle 31 when there is no chance of its being taken up by the air.

In Figs. 4, 5 and 6 a modified construction is shown. In these figures a radiator 40 is shown and this radiator is illustrated as of the type comprising vertically arranged sections connected at top and bottom, which type has been in common use for heating dwellings. Such a radiator is usually much taller than the type shown in Figs. 1, 2 and 3 and with the housing 2'7 of substantially the same height there would thus be a smaller chamber in the housing above the radiator. The housing 27 encloses radiator 40 and said housing has the partitions 28 which parts are the same as already shown and described in Figs. 1 to 3. A casing 41 is provided, disposed in the chamber above radiator 40 within the partitions 28 and said casing has a lower portion 41a extending longitudinally of the radiator 40 and housing 2'? above said radiator. While casing 41 might take various forms in the embodiment of the invention illustrated it is shown as tube-like or substantially tubular in form. Portion 41a has its bottom sloping downwardly somewhat toward its left hand end as shown in Fig. 4 and a drain pipe 42 leads from the lowest point of portion 41a through one partition 28 and then downwardly out of housing 27 between one partition 28 and one end wall 27c. The casing 41 has a return bend or reversely bent portion 41b and the portion 410 extends from this portion 411) above the portion 41a. Portion 41c also extends longitudinally of the housing 27 and as illustrated is disposed above portion 41c. Portion 41c tapers toward its right hand end as shown in Fig. 4 and said portion has extending from one side thereof a nozzle 41d rectangular in transverse cross section and said nozzle has a discharge opening of comparatively narrow and elongated form disposed adjacent the openings We in the front wall 2%. The bottom of nozzle 41d projects somewhat beyond the remainder of the nozzle and a lip 41c extends vertically across the bottom, said lip extending vertically a short distance. The portion 410 is closed at its right hand end as seen in Fig. 4 and the portion 41a is open at its right hand end as seen in said figure. The nozzle 43 is disposed in the end portion of portion 41a, the same being connected to a magnetic valve 44. A water supply pipe 45 is connected to the valve 44. The supply pipe 45 preferably passes through the top of radiator 40 as shown in Fig. 3 so that the water therein will be heated by said radiator. Said pipe also has disposed therein a strainer member 46 disposed between one partition 28 and an end wall 270. An aquastat or thermostat 4'7 is secured to the radiator 40 at one end thereof and this will be connected by electrical conductors (not shown) to the magnetic valve 44. Said valve 44 can also be controlled by a thermostat or humidistat in the rooms to be treated. The casing 41 has secured to the top of portion 410 hooks 48. The hooks 48 are engaged by eyelets at the lower ends of supporting links 49 having eyelets at their upper ends through which pass headed and nutted bolts 50. The bolts 50 pass through and are supported by the bars 51 secured to the side walls 27a and 27b in any suitable manner, as by welding or riveting. The portion 41a of casing 41 also has a hook 52 secured to its top at its free end and this hook engages over a rod 53 supported at its ends on the lugs 54 secured to the inner sides of the walls 27a and 2%.

In operation heat will be supplied to the radiator 40 and (he pipe 45 will be connected to some source of water under pressure such as the city mains. When the temperature in the radiator 40 reaches the desired point, the valve 44 will be opened by action of the thermostat or aquastat 47 and liquid such as water will be sprayed into nozzle 43 and directed into the open end of portion 41a in very finely divided condition or in the form of said liquid preferably being projected in the form of a cone having its apex at said nozzle and its base at the peripheral wall of portion 410.. As already described, the housing 27 has openings at its bottom and the air in the chamber between partitions 28 will be heated and will pass upward and out through the openings 276. Air will also naturally pass through the casing 41 and the movement of the air through the casing will be augmented by the spray from nozzle 43. The finely divided water mixes wi h the air passing through casing 41 and highly humidified air passes from nozzle 41d. This air passing from the nozzle mixes with the air passing up through the casing and out of the openings 27c. Any surplus moisture which might be directed into the casing 41 will drop to the bottom of portion 410,, portion 41b, and portions 410 and 41d and will drain back to the lowest point in said casing and drain out through pipe 42. Pipe 42 will be connected to any suitable drain. The lip 41c at the end of the nozzle 41b insures that no moisture will be carried over the edge so as to drip therefrom. The water sprayed from nozzle 43 passes through the strainer 46 and all solid matter is removed therefrom. Any clogging of the nozzle 43 is thus prevented.

From the above description it is seen that applica-nt has provided a very simple and emcient humidifying device. In both forms shown the interior of the casings, namely casings 30 and 41, will be continuously moist when the device is in operation. This prevents any accumulation of sediment which might be formed from 'i he matter in solution in the water. The shape and size of the casings gives ample opportunity for the moisture sprayed thereinto to thoroughly mix with the air before being discharged. The humidified air being discharged from '1 he nozzles a short dis-- tance from the openings in housing 27 gives opportunity for a further mixing of the humidified air with the air passing through the housing which is not humidified. This insures that there will be no possibility of air passing out from housing 2'! and being oversaurated. The casings 30 and 41 are arranged so that they can be readily removed when desired. It is only necessary to disconnect the drain pipe and then lift the cam j ings from the supporting means. The hooks by which the casings are supported are readily disengaged frorn the supporting members. It is apparent that the device can easily and conveniently be installed over standard radiators now in use. An apparatus which is pleasing in appearance and unobjectionable as living room equipment is thus provided. The device has been amply demonstrated in actual practice and found to be very successful and efficient.
