A dis the inner side of the end wall 16d coaxial ther with and the smaller end of an inner-casing "surrounds said peripheral flange and is secured thereto to be supported thereby. Casing 40 is prises an outer casing 16a shown as of elongated A plug 29 (see Fig. 5). is threaded into the valve 23 and pipe 22 to the nozzle 21.

when not in use. As shown in *Figs. 1 and 4-, the lower block 32 contains a.

like. platej39 having a peripheral flang is secur ed to also in theshape of a frustuin of a cone and has an open large end disposed somewhat adjacent end wall 16%;, the inner end of nozzle 21 being located substantially at the end of casing 40. Casings 16a and to have openings 15c and 40a at one side, extending lengthwise thereof, these openings being alined in the two casings and said openings are spanned by a plurality of members 41 extending tn reac The members 41 are in the shape or'tlie segment of the frustum of a cone and the same have a slightly inturned flange 41a at their larger ends. Members 41 have their smaller ends directed towards the smaller-end of easing 16a and at their ends ongage and are connected to plates 43 which are parallel to the diametral plane extending centraily of the openings in casings 16a and 40.

The plates 43 have one sideeistending along the outer side of casing 40 and secured thereto and their outer edge is bent at an angle and embraced by-the folded end 16f of easing 16a extending alon the side of opening 156. A plate 40?) eaten s across opening 16c at the larger end their of: andbetw'een casings 16a and 40. The member lat thoflarger end of the opening engages this plate lob. Casing 18a has a plurality of openings 16; in its lower side, these openings being in form of elongated slots with semicircul ar ends.

mercoid control'ineinber 44 has connected thereto. {a tube or casing 45 secured in and pass-- ingthrougl 'a plug 46 in the end of the radiator oppositev plug 29, said tube 45 extending some distaniee into the radiator and containing a thern'iostatie element. Tnernercoid control 44 is'provided for regulating the solenoid valve 23 and will be'suitably connected thereto.

In operation, radiator 10 will be as usual provided with a heating medium and as stated, tube 30' will'be connected to a source of water under pressure. The members 44 and 22- will be arranged so that upon the attainment of a certain temperature in the radiator, control member l l'will act to open the solenoid valve 23. The water from tube 30 will be heated in coil or tube 28 so as tobe more readily evaporated .andw'ill pass through strainer-25 so as to be cleared ofall solid matter. When said ature has'been attained, water can pass temperthrough Liquid is projected by nozzle 21 lengthwise of casings 16a and 40 in the form of a very fine mist. Air rising, from radiator 10 passes into casing 16a through the openings 16g and thence to the open end of casing 40 and into said casing. The movement of theair into casing 40 will be induced and assisted by the spray from the nozzle 21. The warm air passing into casing 40 mixes with the finely divided liquid or mist sprayed thereinto and'a good portion of this liquid will be evaporated and pass with the air out between .the' plates 41. "Someof the liquid projected in side thereof, at its smaller end, whichblocks are the fornrof mist will engage the conical surface of the'pl'atesal and as unit 16 including these the air and inlet is thus obtained and the air passing out of casings 40 and 1664 between plates 41 carries the desired amount of evaporated liquid. Any liquid not evaporated and carried out with the air will collect on the bottom of casing 40 at the inner sidethereof and will orain to the large end of easing a0 and drop into the large end of casing 16a as illustrated in Fig. 4. Any such liquid collecting in the larger end of easing 16a will pass out through the nipple 34 into the drain pipe 36 and will be carried away to a suitable drain. The humidified air passing out of easing 16a or unit 16 will pass through the grid 14g and through opening 14 in casing 14. to the rooms to be humidified.

In Figs. 6 and '7 the unit 16 is shown as applied to a radiator of the well known copper plate type. In these figures a casing is shown similar to the casing 14, the same being mounted upon the legs 49. A radiator 51 is provided which is of the type comprising headers 51a between which extend the tubes 51b. The tubes 51?) carry a multiplicity of thin plates 52 of copper or other metal of high conductivity. The plates 52 are shown as being enclosed at the sides in thin metal casings 53. Coupling plugs 54 are threaded into projecting hubs on the headers 51a and the inlet pipe 55 is connected with one of these plugs, the same having connected thereto the shut-off valve 56. The outlet pipe 57 connects with the other plug 54, the same having inserted therein the trap 58. Supplemental end walls or partitions 59 extend from the topof casing 56 downwardly parallel therewith, said partitions terminating at the top of headers 51b and having flanges resting on said headers. The front of casing 50 has an opening 50a therethrough adjacent its top and this opening preferably has a grid 59b therein. The side walls of casing 50 extend down in line with the top of legs 49 so that an opening is provided at the bottom of the casing through which air may enter. A humidifying unit 16 shown in Fig. l-is disposed in the chamber in casing 50 within the. walls 59 and it will be noted that it is disposed with the members 41 and the openings 16c and 40a at the top instead of at the side as in Fig. 1. Rods 60 extend across casing 50, being secured to the sidewalls thereof in any suitable manner and these rods are embraced by the hooks 20 and 19. A liquid supply pipe 61 is provided connecting with an L-coupling 62 threaded into a plug 63. There is one of the plugs 63 threaded into the outer side of each of the headers 51a; A pipe extends between the plug 63 and through one of the radiator pipes 51b. The other plug 63 is connected by-pipe connections 65 to a strainer member 66, a right and left coupling 6'7 being inserted in the pipe 65. Strainer 66 is connected by the pipe connections 68 to a solenoid valve 69 which is in turn connected by a pipe '19 to the nozzle 21 of unit 16. An elbow v'71 is disposed beneath a drain nipple 34 and a drain pipe '72 leads from the nippie 71 to a suitable drain.

In operation heat will be supplied to the radiator 51- and the air in casing 59 particularly within partitions 59 will be heated. The unit 16 will be brought substantially to the temperature in this chamber. The solenoid valve 69 will preferably be controlled by a humidistat in the -.rooms to be humidified. When the humidity falls to a certain point, valve 69 will be opened and when the humidity rises to a certain point, said valve will be closed. Said valve will, of course, be connected to the humidistat by suitable electrical conductors. Said valve could also be connected to a thermostat in the rooms to be humidified so that it would not open unless the temperature in the rooms was at a certain point. Assuming that valve 69 is open, water will be sup- :plied through tube 61 and will be heated in the radiator 51. This water willpass through pipe "through the spaces between members 41.

69 tostrainer 66 and through valve 69 and pipe.

'70 to the nozzle 21. The liquid will be projected lengthwise of casings 16a and 40 as already described and the air rising through the openings 16g in the bottom of the unit 16 and will pass into the open end of casing 40. The air will commingle with the mist projected into said cas ing and a good portion of the liquid so projected will be evaporated and carried with the air out This air will pass out through the grid 5% into the room. As above set forth, any moisture which might strike or collect on the surfaces of members il will be evaporated and will pass out with theair. Should any moisture collect in casing 19, it will drain to the larger end thereof and into casing 16a and will pass out through drain nippic 34 into member '71 and through drain pipe 72. The water supplied to nozzle 21 will be heated in passing through radiator 51 so that it will be the more easily evaporated.

From the above description it is seen that applicant has provided a humidifying structure which can be easily and efliciently used in combination with a radiator or other heating unit. The humidifying unit is simple and compact and yet functions to supply a'large amount of moisture to the places desired. The unit can be readily removed by simply disengaging the hooks which. v

support it. The nozzle 21 can be withdrawn from the sleeve 16c and the unit is then entirely de tached. It can very easily again be placed in operating position. The same is easily and inexpensively made and assembled.

It is possible in some places to use the device without the outer casing 16a. The air then enters the large end of the casing 40 withoutfirst passing through the openings in the bottom of the casing 16a. When casing 16a is used, the air passing upwardly from the radiator passes through the openings in casing 16a and a more uniform movement of the air is secured.

The device has been amply demonstrated in actual practice and found to be very successful and eificient.

It will, of course,.be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the scope of applicants invention, which generally stated, consists in a device capable of carrying out the objects above set forth, in the parts andcombinations of parts disclosed and defined in the appended claims.
