3 Claims.

My invention relates to humidiers, particularly for use in connection with hot water or steam radiators in residences, oilices and all other interiors where it is desirable to increase the humidity in the air during those periods in which the rooms are heated. My humidier also can be used when the roo-ms arev not being heated, as in the summer time, to produce a circulation of washed air.

It is well-known that in the heating of rooms and buildings, particularly in winter time and during extremely cold weather, the humidity falls to a Very low point, often approaching complete dryness. This produces an atmospheric condiion at is injurious o w o worn an i t th t o d d urruture in the building, and also is not conducive to good health conditions. Various means have been suggested for adding humidity to the air under such conditions, and my present invention has for one i of its objects to provide such means which may be connected with or inserted into the customary radiators using steam or hot water, and which, therefore, being embodied in the radiator itself, will not be in any way conspicuous and will operate with a high degree of efficiency, and which is economical to build and install.

The full objects and advantages or my invention will appear in connection with the detailed description thereof, and the novel features of my inventive idea will be particularly pointed out in the claims.

Fig. 5 is a sectional plan view on line 5-5 oi Fig. l.

[is illustrated, radiator sections are of the usual construction, having upper and lower conhector nipples 11 and l2 of usual construction.

My invention is comprised in a casing 13 which may conveniently be oi a width equal to two of the radiator sections 1G, and provided with upper and lower connector nipples 14 and 15, exactly the same as the connector nipples l1 and 12 scepting that they communicate with closed tubular passageways 16 and 17 for conveying the steam through the system. As clearly shown in Fig. 2,

" webs 18 and 19 divide the space within the casing 13 into two side chambers 20 and 2l, and a central (C1, BSI-116) chamber 22. A water pipe 23 passes along the upper steam line of the radiator and through the connecting passageway 16, having branches 24 and 25 passing through packings in the Walls of said passageway 16 which terminate in spray nozzles 26 and 27 located at the top of the side chambers 20 and 21. As shown in Fig. 1, two or more of my humidifying castings may be inserted in any particular radiator, and in such case the pipe 23 will be continuous along the steam line so as to provide branch pipes for each of the sets of side chambers of each humidifier section.

The side chambers 20 and 21 terminate in a top chamber 28 which is provided with a perforated cover plate 29, as clearly shown in Figs. l and 2, with raised portions 30 to make it match in appearance the top oi the radiator sections.

The water pipe 23 is connected with a supply pipe 31 having in it a shut-off valve 32 through a filter device 33 and feeds into nozzles 26 and. 27 in a rotating manner not here claimed, delivering through a central aperture of the nozzle, all in a well-known manner. The result is sprays of water driven downward from the nozzles 26 and 27. As the spray is driven out under system pressure it will move at relatively high speed and the particles of water will catch and carry with the air under friction, drawing air through the perforations in the cover 29.

The bottom of each of chambers 20 and 21 extends into a semicircular passageway 34 and 35 formed by lower semicrcular walls 36 and 37 and a central casting 38 extending upwardly from the wall of steam passageway 17. The semicircular passageway is further accentuated by the semicircular cast segments 39 and 40, forming additional passageway systems 41 and 42. Both sets of passageways 34 and 41, and 35 and 42 discharge upwardly into the bottom of the central chamber 22, and the air drawn down by the spray is forced upwardly in that way by the deflector device thus provided. Here it enters a multiplicity of passages 43 and 44 which discharge through lateral openings 45 and 46 through the walls of casing 10 into the space between the radiator coils, as clearly shown in Figs. 1, 2 and 3. The passageways 43 and 44 with their connected lateral openings 45 and 46 are formed by curved barile plates 47 and 48, as best shown in Fig. 1. These baille plates, together with the curved bottom members 36, 37, 39 and 40 operate to trap and retain any free moisture from the spray, which descends through slits 49 and 50 in partitions 39 and 40, and 51 and 52 in partitions 36 and 37, and from there through drip openings 53 in the bottoms of the casings 10, Where the water discharges to a drain pan 54 which, in turn, discharges through an opening 55 to drain pipe 56 leading to the sewer.

From the above description the operation of my humidifier will be clear. The water pipe running through the center of the main steam feed pipe will convey the water in a heated condition to the nozzles 26 and 27. As the spray is forced downwardly air is drawn through the openings in the perforated top member 29. This air, together with the spray strikes upon the curved. bales 36, 37 and 39, 40 and is turned upwardly into the central chamber 22. There it enters the passageways 43 and 44, being turned out into the space in the room next to hot radiator sections by baie plates 47, 48 to emerge through the passageways 45, 46. During the whole of this travel the air will be in contact with the water of the spray, and with water surfaces within the passageways, by which it will become saturated with Water vapor. At the same time, the action of the baffle plates will be such as to cause deposit of all free water so that the saturated air discharges only with water vapor and without any free Water.

The advantages of my invention will clearly appear in connection with the detailed description heretofore given. Owing to the fact that it is applied in one of the regular radiators, it is not unsightly or conspicuous, and its effectiveness is very greatly increased by reason of the fact that the air is very considerably heated as it contacts with the water vapor. While it is a primary purpose of the invention to apply it in and as a part of a hot water or steam radiator of any type or shape which may be used for heating rooms, it is practicable to use my invention separate from such a radiator both for humidifying air and for washing it when that may be desired. A further advantage of my construction is this: the humidifier sections may, and in practice will, be cast so as to correspond with one or more ordi- L94avce nary radiator sections of the various types which are manufactured and installed, and which have been manufactured and installed. It follows, therefore, that my humidier may readily be inserted in the radiation of residences and other buildings already constructed and provided with steam or hot water radiation.

I claim:

1. A humidier comprising a casing with means for inserting the same into a steam or hot water radiator in communication with the upper and lower conveyor lines for the heating medium, a water pipe extending through said conveyor line and connecting with a nozzle within the chamber of the casing, and said nozzle spraying water through said chamber, and means for admitting air into said chamber adjacent said nozzle and for permitting it to escape from said chamber at another point whereby the air is caused to be drawn into the chamber and expelled therefrom in a moistened condition.

2. A humidier 'comprising a casing having a plurality of chambers, one of which is open at its end adjacent the bottom of the other, with a multiplicity of curved baffle plates forming curved passageways with lateral openings in the side of said first-named chamber, means for spraying water into the second-named chamber, means for admitting air thereto adjacent said spraying means, said spraying means acting to move the air.

3. A humidier comprising a casing having a plurality of chambers, one of which is open at its end adjacent an end of the other, with a multiplicity of curved baffle plates forming curved passageways with lateral openings in the side of said rst-narned chamber, means for spraying water into the second-named chamber, means for admitting air thereto adjacent said spraying means, said spraying means acting to move the air.
