' AIR-cooLIN-e r.einenEarns.

To all whom it may concern:

Be it known that. I, GENNARO DRAMIS, a

lsubject of the King of Italy, a residingl at Brooklyn,"in the county olf/Kings and State of New York, have invented an Air-Cooling Apparatus, of whichthe followingis a specificatlon.

The present invention relates -tol certain new and useful improvements in -yentilating and cooling apparatus, andthe object'of the invention isl the provision of adevi'ceof this character, which embodies` novel features of construction whereby air may' be effectively. cooled and forcedlnto the .room cr'other compartment.' 'i y The invention .further contemplates a ventilating" and air cooling. device which is inexpensive inits construction,` which can be .operated at a comparatively small cost, and which can be easily and quickly installed in operative position.

l `Wit-h these and other objects in View, theinvention consistsin certain combinations and arrangements of the parts as will. more fully appearas the descriptionproceeds, the novel features thereofbelng vpointed out in the appended claims. f 1

For a full understanding of t-heinvention,

reference is to be had to the following de- Scription and WhichrfY .v

Figure 1 is a vertical. sectional` view' through .a ventilator and air cooling device constructed in accordance with the invenaccompanying drawing,l in

tion, and Fig'. 2 is a transverse sectional view on the line 2 2 of Fig. 1..

. Correspondng and like parts `are referred to" in the. following description and indicated in all the-views ofthe drawing by the same reference character. l v

Referring to the drawing, the numeral'l designates a casing4 which is substantially; cylindrical in shapefand .is provided with abase 2 which serves to-hold it normally in an upright position. 4'Ifheends ofthe, .cas`i ng are formed with suitable bear-ings l `thin y which a shaft- 3 is journaled, the Sagl-.shaft being designed to receivefmoti'onfrox a suitable motor or othersource ofV ower', and the portion `of the shaft within t e casing havmg`a centrifugalfan mounted thereon. One,`

or bothends. of the casing `are provided at apoint toward the center thereof with a series of air-inlet openings 4,'while the periphery of the casing is provided at the top thereof with-an outlet 4pipe the eentrifuf i "specification of Lett-ersrateaef' gal fano erating to suck air through .the inlets 4, an discharge it through' they outlet 5. Specifically describing the centrifugal fan',

the said Vmember vcomprises a pair of yend' plates 6. which are formedwith correspondlngradial arms 6a, the said arms'upon the two plates being connected by the transverse plates orwalls 7 so. that the fan'has a hollow formation.' It willalso be observed'that the 'central points* o ,f the endplates 6 are con.- nected by aslee've 8- whichtits Yover the shaft 3.t A. suitableopening is. rovided in the point'if one ofthe wings 4o the star shaped .fan for filling the interior of the fan with somel liquid such as water, the saidopening being normally closedingsome s?, 'tableJnanner as by ymeansofa plug-x9. 1T, -e water Aor A other liquid which may thus loe placed within the star shaped centrifugal fan will assist in changing the temperature ofthe 'air b'e-A fore it is finally dischargedlhfroni the ventilating device. y a

A' stri of'fabric or tissue A10 is extended around -t e fan and'litsclosel againstjthe' p t vPatented Dee. 6, 1910.` f-Appucationnlea nedem'ber e, 1909. semi Np. 531,738;

sides of the various blades tereof. This v strip offabric preferabl has substantially the same width' as the an' and is held in position thereon by means :of a series of re taining rods '11, 'which `are y arranged be-4 tween ythe-blades ofi the fan at .the inner ends thereo'i," Theserods '11 may ybe held in position inany suitable manner, and in thepresent instance, theendsthereof'are shown'a's enga-ging portins'of 'the lend plates a'blng'this tissue or-'fabric 10 to'beplaced in .position orzremoved therefrom as may be found desirable, -a doorv 12 isf provided in one .-side of thecasing l, the said-door being air .stight when -closed so as not to`interfere 1n any mannerwithzthe' action ofthe centrifugal fan. A .water pipe 1'3 vleads from some 10u. ysuitable receptacle tofthe topof the casing mnd ,is 'roviaed aan suitabiepoinein as receptacle is preferably placed in'an' ele length with astopcock- 14.." for contrtlling the ilow of water therethrough.; The water vated position so. ythat water'L-zwill- -flowthrough the pipe "l by thehactionf'gran-14 ity. A perforated plate or screen 15 1s provided atthe point where the-waterpipe-lii f f 9ol 6, which-are snitablyy "ezi'psfed at `thel points wherethe sides'of the variousbladesl intersect. each other. For thefpurpo'se -of -enfrom the Wet fabric l0." This evaporation centrifugal fan. A water 'outlet pipe '.416 leads from the bottom of the casing l/and 'may be suitably curved as shownso'as tol act as a Siphon and forma Water seal.,`

When the fan isinpperation, air' will be drawn into the casing-through" the Vair inlet openings 4 vfrom the 'exterior atmosphere and -will produce an evaporation of moist-urel of the Water will servel'toV absorb heat and lower thejtemperature of the air so that the -said l'air will be effectively cooledbefore .being linallyoischarged into the room` vor f apartment through the air outlet pipe v5.
