.UNITED STATES GEORGE 0. BROWN, or woRcnSTER, MASSAoHUsETTs I EUMIDIFYING APPARATUS Application filed May 28,

This invention relates to apparatus for humidifying the air in a dwelling-house and in other buildings. heated by steam or hotwater. It is well known that the air in such buildings is commonly lacking in moisture, and that a substantially lower temperature will be found comfortable and satisfactory if the moisture content of the air is increased.

It'is the general object of my invention to provide an improved and more effective humidifying apparatus for such purposes, which apparatus may be easily manufactured and installed and which will be found reliable and satisfactory in use.

With this general object in'view, important features of the invention relate to the provision of removable evaporating units of an improved design and construction, and to the provision of improved means for supplying moisture to Said evaporating units.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claim.

A preferred form of the invention is shown in the drawing, in which Fig. 1 is an end elevation of a steam or hot-water radiator having my invention applied thereto;

Fig. 2 is a side elevation of the radiator and humidifying apparatus, looking in the direction of the arrow 2 in Fig. 1;

Fig. 3 is a partial perspective view of thewater supply and spray pipes;

Fig. 4 is a side elevation of one of the evaporating units with a portion of the covering broken away, and

Fig. 5 is an end view of one of the upper evaporating units, looking in the direction of the arrow 5 in Fig. 2.

Referring to the drawing, I have shown a radiator R of an ordinary commercial design and formed of sections, each having a plurality of openings 10 formed therein. These 45 openings are arranged in parallel vertical series and are aligned in the different sections to provide continuous passages through the full length of the radiator.

My improved evaporating units E are 50 placed in the aligned openings 10. Each unit 1931. Serial No; 540,701. 7

E. preferably comprises a bag orcasing 2O of some suitable woven material, preferably linen, and an open frame-work 21 adaptedto be inserted inthe bagor casing 20 andto' hold the same in fiat distended condition.

The frame-work 21 may conveniently be provided with a handle portion 22 at one end, by which insertion and removal of the evaporating unit in the opening 10 is facilitated.

g The moisture for'the evaporating units E is provided byasupply pipe (Fig. 2) which may be in the basement of the build ingand may be connected to the usual water main. I. have shown the supplypipe 3O as connected to a shut-ofiv valve 31', a filter 32, and a reducing valve'33, all of usual commercial construction. I i

' A pipe 34 leads upward from the reducing valve 33 tov a needle valve 35, and a pipe 36 extends upward from the needle valve to a fitting 37conneoted to forked or branched sprayp'ipes38. i e v One of these spray pipes 38 is rovided for each'vertical series of openings 10 in the radiator'R. 'These spray'pipes 38 are provided with suitablesmall' openings, spaced throughout their length and delivering water inthe form of drop so'r a finespray tothe evaporating units. V I Preferably, the casing 20 of each upper evaporating unit is provided with ajsmall opening at the closed end of the casing, permitting the casing to be slipped over the free end of a spray pipe 38, so that'the spray pipe is disposed within the casing, as clearly shown in Fig. 5.

Having described the details of construction, the operation andadvantages of my improved humidifying-apparatus' will be readilyapparent." The reducing valve 33 provides low pressure water for the needle valve 35, which may be setto allow thewater to pass through the valve at any desired slow rate. This water is distributed through the spray pipes 38 to the upper evaporating units E and the surplus water drips down to the lower evaporating units.

If the radiators are cool or if for any other reason the water is not all evaporated, the

several important advantages.

surplus Water drips into a pan 40 which is placed on the floor under the radiator R and which may be connected to a suitable Wastepipe 41.

The apparatus as above described possesses It provides a continuous and definite supply of Water for evaporative purposes, which water is. distrib uted under'conditions mostadvantageous for evaporation. The linen casings 20 readily receive this Water? andrhold itgelqsely adja; cent to the hot radiator surfaces. The evaporating upits E may be readily removed2when desired and the casings 20 may be easily slipped oft of the frames-21- f0I'--W&Sliihg0ireplacement.
