HUMIDIFIER.

.Application led March 19, 1226. Serial No. 95,903.

My invention provides a simple and ecient humidifier for application to steam and hotl water radiators and, generally stated, consists of the novel devices, combinations of devices and arran ement of parts hereinafter described and de ed in the claims.

The humidifer includes a spraying nozzle in fanshaped water or vapor film in a plane parallel and adjacent to one sideof the radiator; and this spraying nozzleis associated with an u right shield that operates as a "splash boar and is connected at its bottom to a drip pan.

The shield is preferably located just back of the radiator or between the radiator and the wall and the vapor lm is projected in lthe space between the shield and the back of the radiator. The above and other minor but important features will appear in the following description of the invention as illustrated in the drawings.

Referring to the drawings wherein like characters indicate like parts throughout the several views,

Fig. 1 is a ,front elevation view showing an ordinary steam or hot water radiator, the circulating pipes thereto and therefrom and the valves therefor not being shown;

Fig. 2 is a vertical section taken on the line 2-2 of Fig. 1;

Fig. 3 is a perspective showing the shield and drip pan removed from working position;

Fig. 4 is a detail partlyin elevation and partly in axial section showing a filteringI device interposedin the water supply pipe to the spraying nozzle;

Fig. 5 is a detail view partly in front elevation and partly` in axial section showing the spraying nozzle and coupling to which it is attached;

Fig. 6 is a detail in section on the line 6--6 of Fig. 5;

Figs. 7,18 and 9 are detail views in elevation illustrating progressive steps in the making of the spraying nozzle; and

Fig. 10 is a ragmentary elevation illustrating a plural arrangement of spraying nozzles.

rihe numeral 10 indicates an ordinary steam or hot water radiator made up of sections connected in the customary way and as usual mounted adjacent to a wall A. Arranged just back of the radiator and between the same and the wall is an upright shield l1 preferably of sheet metal formed with upright side flanges 12 and with a flanged upper portion 13. In-the preferred arran ement, this shield is, at its lower portion, t'

ted into a drip pan 14, and it will be notedl that the side anges 12 are fitted against the end flanges 14a of said drip pan.

By reference to Fig. 1, it will be seen that the drip pan and shield are slightly shorter than the radiator so that the pan will pass between-the longitudinally spaced legs of the radiator and the side flanges 12 will align with lspaces between the extreme end-and adjacent radiator sections. By reference to Fig. 2, it will be notedthat the drip pan is so set that it underlies most of the radiator and that the vertical iianges 12 will project slightly into .the spaces between theradiator sections, thereby producing an underlapping of said ilanges 12 with the radiator sections. The drip pan 14 is shown as provided with a drain pipe 15 to carry off surplus water.

The nozzle employed for producing the very thin fan-like spray of water is so located that the vapor spray thereof will be projected in a vertical .plane in the space directly between the shield and the radiator. This nozzle is formed with an externally threaded tubular shank 16 and with a head 17, which latter has a very narrow diametrical discharge passage 18. The nozzle may be supported 1n various different ways and connected to any suitable source of water supply ed under pressure. As shown, its threa shank 16 is screwed into theupturned ni ple of a i"'coupling 19 into the opposite en s of which horizontal

coupling pipe sections

20 and 21 are tted. rlhe outer end of the pipe 21 is closed by a cap 22. The extendedA end of the pipe 20 is connected to the casing of a valve 23-that receives water from a suitable source under pressure such as the city water main connection, through a pipe 24.

The discharge passage 18 of the nozzle is so thin that it might be plugged by even quite small objects carried in the water and, hence, to remove such objects from the water, I preferably use a lter. This lter, as shown, is afforded by a filtering material 25 contained in a. tube 26 that is lnterposed in the pipe 20, and is connected thereto by a reducing coupling 27 and by'a pipe union 28. This discharge passage 18 is primarily formed by sawing a slit 18 through the head 17, asbest shown in'Fig. 7. rlfhis slit 18 will beformed by a very thin saw. Then of a mist.

the slit head is pressed together, as shown in Fig. 8, and then the extreme sides of the head are closed by solder 18", as best shown in Figs. 5 and 9. The thickness of the slit 18a and the formed discharge passage 18 is much exaggerated in the drawings. In fact, the discharge passage 18 is so extremely thin,

less than that of ordinary writing paper), t at the spray of water dischar ed therefrom in the angle between the ra iatin arrows marked on Fig. 1 Ywill be in the orm This mist-like thin fan-shaped spray will be projected primaril in the space between the radiator and t e shield and will be stopped by the vertical flanges 12, but some of the mist will be lodged on the radiator, and the latter, being hot, will increase the rate oiievaporation. The hot air in the space between the radiator and shield will, of course, move upward, and as the water spray is projected in an upward direction and is of mist-like form, the evaporation will be rapid and. the vapor will be carried upward and into the room. The rate of evaporation is increased to a maximum and the precipitation of the water into the drip pan will be decreased to a minimum by the fact that the spray is projected upwardly and into the upwardly movingfhot air current. With the flanges 12 interlapped with the sections of the radiator, no space is left through which any part of the spray can be projected directly out of the space between the radiator and shield and hence the water discharged from the nozzle must either be evaporated and carried u ward with the air current or be precipitate onto the drip pan.

The eliciency of this humidifier has been demonstrated in practice. It has been the common fault with humiditiers hitherto rovided that they lack capacity to pro uce that kind of moisture that is required in a room or building heated by steam, water or vapor. By means of the valve 23 the supply of water to the nozzle and hence the amount and when the water de 'very is set for a maximum the evaporation of water into the air will be correspondingl increased to meet any requirements. The liumidilier has the further advantage that it may be readily applied to the radiator of any hot water, vapor or steam heating system, and is of low cost.

By reference to Figs. 1, 2 and 3, it will be noted that the water supply pipe 20-21 is extended through the side flan es 12 of the shield 11 and is supported there y, with the cap 22 and the valve casing 23 just outside of the shield.

Fig. 10 illustrates a modified arrangement in which several of the s raying nozzles 17 are connected by T-coup ings 29 to a supplemental water supply pipe 30, which, 1n turn, is connected b a short pipe section 31 to the water supp y pipe 20-21.

Noclaim is herein made to the specific form of operating nozzle, and so far as this invention is concerned, an suitable spraying nozzle .may be cmployed What I claim is:

1. The combination with a radiator and an upright shield located adjacent to one side thereof, of a nozzle arranged to project a spray upwardly in the space between said radiator and shield, and means for supplying water under pressure to the nozzle.

2. .The combination with a radiator and an upright shield located adjacent to one side thereof, of a nozzle arranged to project a spray upwardly in the space between said radiator and shield, means for supplying water under pressure to the nozzle, and a drip pan extending from the bottom of said shield and under the radiator.

3. Ihe structure defined in claim 2 in which said drip pan and shield are independently formed, but in which the former tits within the latter.

4. The structure defined in claim 2 in which the shield has flanges' and in which the means for supplying water to the nozzle under pressure includes a cross pipe seated in the angesof said shield.

In testimony whereof I afiix my signature.
