To all whom it may concern: i

Be it known that I, WILLIAM E. TAYLOR, a citizen of the United States, residing at the city of Toledo, county of Lucas, State of Ohio, have invented certain new and useful Im rovements in A paratus for Tempering an( Purifying Air, o which the following is a specification.

This invention relates to improvements in apparatus for washing, puriiying and tempering air to the proper degree of heat and unidit i The ohjects of thi invention are: first, to

,provide an improved apparatus *for removing A structure embed 'ng the features of my i invention is clearly il ustrated in the acconpanying drawing, formi'ng a part of this specification, in which:

l igure 1 is a sectional plan view of my improved apparatus taken on a line corresponding to line 1-`1 of Iiig. 2; and Fig. 2 is a vertical sectional elevaton taken on a line correspondin r to line 2-2 of l ig. 1.

ln the rawing similar nunerals of refer-` ence refer to similar parte throughout the several views.

Considering the numbered parte of the drawing, I would state that my improved apparatus is intended for purifyng, tempe'ing and regulating the humdity of' air that may be delivered to an ofiice building, factory, auditorium, dwelling or the like.

It consists of a series of comnartments or rooms through which the air is delivered.

An intake 1 takes the air from the outside and is controlled by the damper or door i', the air entering a room 2 from which it delivers to a conpartment or room 5. A temring coil 4 is provided in anopenin in the wall between these two rooms, and a amper 3 controls an aperture heneath the tempermg coil, so that, by controlling the dam er 3,

which may be automatically controlle by a suitable thermostat, if desired, the temperature of the air is very readily regulated independent of the temperature of the coil 4 through which a portion or all of the air may be iorced to pass, depending on the position of the damper 3. The air thus tempered to any predeternined temperature is received in conpartnent 5, and n the Winter time it is very necessary that this temperature be well above tl1e"freezing point n order ,to secure proper results. In the summer time a tempering coil 'isunnecessary to protect from outside influences of the air. `he air thus tempered in thechanher 5 is passed through the ilue 6 where it is directed against the regularly recurved wall 7, and its direction entirely reversed when it delivers backwardly against the recurved wall 10.

A Water "pipe 9 is provided With spi-ay heads arranged to deliyer a double curtain of water across the current of advancing air, and a similar water pipe 12 With spray head 11 is rovded in the passage, where it is re- Verse, so that any air passing from the chamber 5 Will be substantially reverted on V itself twice. The complete curtain of water efi'ectively dampens and carries down any ordinary particles of dust, but the peculiar lamp-black soot from soft coal, and other light, ieathery impurities are not all thus efectively collected. The spray completely moistens the'recurved surfaces, and the air in passing through these ourved surfaccs gradually reverts, so that substantially the entire column of air, Where it is passed through one curved surface and then. reversed to another curved surface', comes in contact with the thoroughly moistened surface, and as the air z is passing ra idly along these sui-faces, the the light, featliery soot and other similar light dust is brought into contact With the wet surface, and the flow of Water down over the same washes it down the surface of tle wall of the compartment '13 into the tank 13' bellO supply means is provided for maintaining the water at the`proper level in this tank, as a suitable fioat or other means. 'l`he water from the tank is used over and over a ain, and passs through the spray heads, as will herenafter indicate, the spray heads being provided with means for throwing them o en to flush out and wash away any sediment t at might tend to clog the same. A tempering 'coil 30 is placed in this tank 13' to warm the water in Winter or to cool it in summer, some refrigerating fluid being circulated through the same in the summer time. head feature is not detailed here, as this i-nvention does not pertain to its structure in detail. The air in passing from chamber 13 passes 'through battle chamber '14, which is provided With the angular shaped upright baflie plates 1'5, the same being sta gered in their relation to each other with t e angles pointingl in the direction of theflow of the air, so t at the open-tear sides collect the free moisture in the air and deliver it downwardl onto the ledge and back into the tank 13'. he air, without free moisture, thus enters the chamber 16 from which it is free to circulate and pass to the chamber 19, heating coils 17 being provided in the intervening wall with a damper 18 beneath, whereby the flow of air can be regulated and its temperature controlled. The air thus enters the chamber 19 where it is taken up by the fan or inexpensve.

desire to remark that t e details of this a paratus and structure can be greatly vared without departing from my invention. I have provided an electric motor 29 for actuatin a pump 25 for circulating the water from t e tank throu h the spray heads, but it is clear that any ind of amotor can be used for that purpose, and tha-timy pressure can be supplied for the sprayheads; and also that the water can be drained awayndused but once Where for any reason the air is especially impure, or water is very abundant or The dampr or tempering coilwhich {have shown between the compartments I find to be best for the u'rpose,' but other 'means might eflectively e used fortem ring the air, though it might not, of course, e so read- I controlled as by the meais'which I` have strated, because here the degree of the temperature 'can "be controlled through a The spray wide degreeb merel .controlling the damper, which w' compe more or lessof the air to crculate over the tenperin'g coil.

The tempering coils provided are for v controlling the temperature of the air, and the temperature may be raised by a circulation of stean or hot -water in these coils when the air is colder than desired, and when the air is warmer than is desired, its temperature can be lowered by the circulation of suitable refrigerating mixtures or by cold water or brme, as the case may be. I desire to remark, however, that the humidity and temperature of the air for use in a dwelling room is best controlled by saturat- `ing the air with moisture at a lower temperature than is desired and then expanding the air somewhat by heat in-the temperng coil 17, which has the eiect of e iminating dampness and insuringthe exactly correct degree of humidity. e I I 'l`he reverted passage-wa for the air with the curved sides can e a-ranged in different positions so long as the air is The term curtain of water, as here used,`

is-intended to embrace 'a spray which extends substantially across the passage to 'thoroughly m'oisten the air and prevent an of the air passing without Contacting wit the water. i
