To all whom it may concern.

' Be it known that I, FREDERICK WHITE, a

South Boston, in the county of Sufiolkand State of Massachusetts, have invented certain new and useful Improvements in Ap aratus for Treating Air, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention is an improvement on Frede'rick Whites prior apparatus for drying or in dwellings, hospitals,

moistening and purl 'ng or medicating air stores, ofiices, factories, restaurants, &c. The prior apparatus is the subject-matter of patents or patent ap- .plications in many countries.

' As generally installed the prior and pres- I cut apparatus take air from near the ceiling and force the air. over a large number of gravitating films of water or other liquid ofany desired kind and temperature and then force the air back into the room, the air being continuously moved with maximum obtainable rapidity in a plurality of currents overa plurality of films of liquid. The velocity, with' which the man-currents pass through the'apparatus is a matter of utmost importanceformaintenance of constant and efficient treatment or modification of the air, and it is necessary to maintain the liquid in film-like form and to distribute the liquid slowly in order to prevent the liquid from choking the interspaces between cylinders on the Walls of which the liquid-films are formed, because if such interspaces were choked with liquid the free and continuous passage of the air through the interspac'es would be obstructed. It is the apparatusshould operate without spattering liquid outwardly and with a mini mum ofQnoise. If the liquid films are colder than the'air passed over them, then moisture in the air deposits on the colder films, and the air is thus dried by deposition of its moisture. If the liquid films are warmer than the air, then the air takes up moisture The apparatus in all cases purifies the air,

because air in passing through the apparatus of a new liquid-distributer detache is an enlar tor-wheel and air-fan.

Verti'calhhaft 4 carries motor-wheel 5, driven b a liquid jet from nozzle 6, having a regu ating-screW 7 controlling the amount of liquid discharged against and also the s eed of the wheel; From casing 1 liquid fall; into distributor 8, fast on the lower end of sleeve 9, which incloses shaft 4 and is threaded into a ballbearing device that comprises stationary ring 10, having an annular exterior circumferential shoulder a resting on collar 11, con- 7 The upper side of ring 10 supports balls b,-on which rests rin'g12, threaded on annular nut 13, in the lower end. of which sleeve 9 is threaded. Sleeve 9, carrying'distributer 8, is free to rotate on balls 1). Auxiliary balls between ring 10 and flange d of nut l, a so support and serve to steady sleeve 9'1n its rotation; Ring 12 carries four thread-socketed radial arms 14, on the outer ends of which inclined vanes 15 are fast and'against which liquid falling from the wheel strikes to rotate the distributer, the liquid falling past vanes 15, through than that ol' the wheel and tan.

rotatable distributer on a stationary part of" the apparatus inst ad ot on a collar fixed on shaft 4, as heretol'ore, is to prote t shalt t l'rom being cut into and weakened by grinding action of grit in the liquid, and herein is an important improvement on prior apparatus of this type.

Distributor-arms 17 are now trouglnshaped in cross-section, prel'erably tapering outwardlylromtheir junction with central cup 16. The sides ol the troughed arms now have alternating solid parts is and exitnotehes l l), the solid parts to ol' each side being eppositeanotch19in the opposite wall. The under side of each distributing-arm is formed with a downwardly-extending projection 20 below each notch it) and with a lownwardlyextending notch 21 below each solid part l8, there being a central lengthwise groove 22 along the under side of each distrilnitingarm, which preferably has an end .liseharge port 23. l;l 1e purpose ol this construction oi" the listril'urting-arms is to secure a distribution ol" liquid from the distributer in a great number of separate streams, which are formed by passe "e of liquid through notches it) in the sides ol the tr'oughed arms. The separate streams flowing out through notches 12) would run together and form continuous sheets below the lower outer corners of the arms it'it were not for the projections 20 and notches 21, which maintain the separate streams intact when they fall on, over, and between the subjacent concentric sheetmetal cylinders 26, which are apt to become choked with lluid l'al'ling in sheet l'orm trout the distributer. Groove 22 secures two rows of separate streams from each arm. This construction secures a maximum number 01 these separate streams from each side of each (.listributer arm.

Casing l is supported on open frame 24-, resting on open-ended cylindrical shell 25, within which said cylinders are mounted and separated by small blocks 27 at intervals 'apart to keep the cylinders stationary. The

cylinders rest on an open cross-frame. 28, last to shell 25, shalt t passing downwardly through. the inner cylinder and carrying immediately below l'rame 28 a sound-deadening arrangement ol inclined raiHal-separated battle-plates 2), the outer ends ot which have cars 30, through which fasteners 31 pass into slllOll 25. The upper edge of each battle p ate has a depending lip 32 eXt6IKllD f1'0Hl end to end ol the plate to prevent liquid on its upper edge from running down its under side and from directly striking on the subjacent air-v lan. The lower edge of each baffle-plate has an upturned lip 33, which extends from end to end of the plate and prevents unimpeded llow of liquid down the upper side of the plate. Therefore when the liquid falls from the cylinders it does not strike directly. a ainst the vanes ot the air-fan, and noise From such cause is diminished. The inner ends of plates 29 are secured to a central ring 34, which is fast to central ring. 34* of frame 28,

shaft 4 passing freely through both rings.-

An air-fan having blades 35 is fast to the bottom of shaft 4, which rests on a ball-bearing 36. The air-fan pulls air through the interspaees of the cylinders over gravitating lluid lilms thereon. Ball-bearing 36 is indirectly supported on conical frame 37 in pan 38. sheetanetal bowl-like deflector 39, the outer margin of which is-secured t0 the edge of the pan at 40, has a bottom portion 41, which lines the bottom of the pan, and this deflector, together with the pan side and bottom, terms a dead-air space 42 around the lower corn er ol the pan. This dead-air space tends to prevent the deposition of moisture from exterior atmosphere on the outside of the pan, and consequently to prevent dripping from the machine.

An 0utwardly-extending annular deflector L3 is last to the bottom of shell 25, and its. upper side supports the ornamental open ended cylindrical casing 44, through which l'asteners 45 passand engage shell 25 to hold the casing in place. Casing 44 may be omit ted; but it is desirable and extends Well above the cylinders and shell to prevent liqaid from being spattered out at the upper end of the apparatus. The lower edges of shell 25 and delleetor 43 rest on ledges a: in the bottom of an annular trough 46 in 0 en cross-frame L7 being clamped therein by asteners 1 From the bottomof the trough vertical discharge-tubes 18 depend, diseharging into the pan liquid which runs down the shell into the trough. A liquidsupply pi )e 49 extends from any suitable source under head to jet-nozzle 6. 50 is the liquid-discharge pipe trom the pan.

Between deflectors 39 and 43 an annulus of inclined ballle-plates51 is mounted, the in into openings through which the supply and 29 overhangs its subjacent plate and An upwardly and outwardly extending wardly with "iolenee and would tend to muse outward spattering were it not for the T he'crosswise arrangement tends to prevent liquid from being; spattercd out between the b aille-plates. The air-fan expels air freely out between the ballle-plates, the air being deflected by cover 54 and deflectors 39 and 43 through space 55. By carrying the lower ends of tubes 48 below the lower edge of battle-plates 5], the air-blast does not drive the liquid (falling from the tubes) through the space 55, as might otherwise happen.

The apparatus is adapted for overhead use, and 56 indicates a tubular standard on wh ch the apparatus may be supported near the for the upper bearing of the shaft.
