claims.

`1 l This invention relates to evaporative air cooling apparatus and more particularly to water elevating and distributing means for evaporative coolers of the multi-filter type.

The principal object of the invention is to provide improved means for delivering water in substantially equal volume to each of a plurality of angularly related lter mats in an evaporative cooler such as described in U. S. Letters Patents Nos. 2,296,155 and Re. 22,675 wherein side mats converge rearwardly towards a rear mat disposed transverse to the stream of air caused to pass therethrough by means of a blower situated between the side mats. To avoid the conventional but impractical method of elevating Water by pump action and distributing the same by means of troughs located along the upper edges of the filter mats, the present invention provides a water elevating unit disposed in the water basin of the cooling apparatus which consists of two discs of different diameters, one being partially submerged in the water Vof the basin to elevate and transfer water to the other. By virtue of the high speed of rotation of these discs, water is discharged tangentiallyv off the perimeter of the discs upwardly, the direction of thrust from the larger of the discs being predetermined and controlled by an adjustable baiiie adjacent its periphery while the discharge from the companion disc `is controlled by causing water collected off the face of the larger disc to impinge the confronting face of the said companion disc at a predetermined point thereon.

Another object of the invention is to provide an arcuated water collecting and distributing plate disposed above the filter mat assembly against which water thrown upwardly by the discs impinges at preselected points. To complete the assembly, the invention further provides water sheds or baffles alongside the side mats into the rear ends of which water is discharged from the collecting plate for distribution onto the said side mats to saturate the same.

With the foregoing objects as paramount, the invention has further reference to certain features of accomplishment which will become apparent as the description proceeds, taken in connection with the accompanying drawing wherein: Y

Figure 1 is a rear perspective view of an evaporative cooling apparatus showing the water e1- evating and distributing assembly installed.

Figure 2 is a detail perspective View of the arcuated collecting and distributing plate per se.

` Figure 3 is a fragmentary perspective view of istv one of the side mats, showing a Water shed and the relationship therewith of the collectingr and distributing plate, the latter being fragmentarily shown in dotted lines.

Figure 4 is a perspective view of the Water elevating unit.

Figure 5 is a side elevational view thereof on enlarged scale, and

Figure 6 is a rear elevational view of the water elevating unit.

Continuing with a more detailed description `of i the drawings, reference is primarily made to Figures 1 to 3 wherein numeral I0 denotes a cabinet of conventional design and also conventional are the air iilter mats II and I2. The mat II is disposed at the rear and the side mats I2 are disposed at relative angles and converge rearwardly, thus defining between their outer surfaces and the side walls of the cabinet substantially triangular spaces serving as moisture collecting chambers. The mat assembly is mounted removably on skids I3.

As stated. it is the intent of the invention to provide for equal distribution of water on the mats II and I2 from a single point without the aid of a pump and distributing troughs usually situated above the mats or along their upper edges. Due to the necessity in many cases for mounting the cooling unit outdoors, it is impossible to obviate collection of foreign matter in the water of the basin I4 and this foreign matter not only causes frequent fouling of the pump but if elevated with water delivered by the pump, such foreign matter collects on the mats and in the case of animal and vegetable matter decaying thereof gives rise to unpleasant odors difiicult to remove.

As will become apparent presently, the invention provides a single unit for elevating and distributing water to all of the mats simultaneously and the very minimum of foreign matter reaches the mats by virtue of the fact that gravity will cause the heavier of the particles of solid matter to precipitate out of the streams of water as they are projected upwardly to be transported in part to the side mats and caused to enter the rear mat under influence of the blower.

Accordingly, the water elevating unit consists of a base I5, the rear portion of which is formed with Va narrow cavity having a curved bottom a (Fig. 5). A portion of the base extends forwardly and is disposed rearwardly of a disc I6 which may, for identication purposes, be referred toY hereinafter as the major disc while a smaller disc I'I, mounted on the samev axis I8wil1 be re1- ferred to as the minor disc. It is to be noted in Figure that the perimeter of the major disc conforms nearly to the contour of the bottom a of the cavity in the base into which part of the major disc extends. The shaft I8 of the two discs is journaled in bearings I9 mounted or formed on the top of the base element I5.

The base I5 is provided with supporting arms 20 which are bolted or otherwise secured to the skid I3 supporting the rear mat I I and by which the said base is mounted.

Mounted on one side of the base I5 is a stripping tube 2| whose end nearest the major disc I6 is of greater width than the discharge or nozzle end b which is in juxtaposed relation to the confronting face of the minor disc I'I and spaced inwardly from the perimeter thereof. Moreover, it is pointed out that the tube 2| is disposed at an angle to the plane of the face of disc I'I for the purpose to become apparent presently.

The stripping tube 2| has a lip 2v2 overreaching the edge ofthe cavity in the base in which the major discY I6 operates and this lip is in near contiguity with the face of said' discr I6 and parallel therewith.

The base I5 is but partially submerged in the water of the basin. I4 to a depth insulicient to permit the minor disc I1 to enter the' water. The water level at its peak is suggested byV the dotted line crossing Figure 5 and is show-n' to be below the minor disc I1 but the disc I5 is shown asbeing partially submerged.

A motor 23 (Fig- 1V) adequately sealed against moisture is disposed' inwardly of the rear mat Il and drives shaft I8 at a high rate of speed', causing the discs I6 and ILI to revolve at the same speed. Water is elevated by the disc I6 by surface tension and is stripped off by the lip 2.2 of tube 2i and caused thereby to be projected through the tube 2I onto theface of the rapidly revolving disc I'i. The water is discharged tangentially olf the disc II, taking the path substantially as shown by arrows in Figure l or towards the upper left hand cor-ner ofthe cabinet 91 and in impinging the downwardly curved portion c of a collecting and distributing plate 24, the water follows the curve of the-plate and fallsupon the' extendedV end25 (Fig. 3) of a shed or baffle 2B.

As shown in Figure 3, the sheds 25 which are identical in construction and-position on each side of the cabinet, occupy the triangular moisture collecting chambers between theside pads l2 and side walls of the cabinet. The sheds are-slightly inclinedtowards the rear of the cabinet as welll as laterally towards the side mats I2 and their inner or discharge edges lie in recesses il' (Fig. '3i in the outer surfaces of the mats. Hence, the water delivered onto the ends of these sheds by the collectingplateZwillflow at oncetowards the forward end ofthe shed andoithedischarge edge thereof' throughout its length to enter the adjacent mat and maintain saturationthereof.

Simultaneous with the foregoing function a separate discharge ofwate-rvis made off theperirmeter of the major ,disc Iwhichtales-the courseshown by the arrows to the right4 inFigu-re l, i. e., upwardly towards and against the-'downwardly curved endvd ofthe collecting platel, to be discharged thereby onto theeXtended end 2550i the opposite shed Y 2" and similarl.v distributed along the outer surface of the companion sidey padnear its top, shown. Y

It is to be particularly observedthat the curva'- ture of the colllecti-ng-platet do'esn'otrepresent a true centered arev but instead is distortedv to dispose the portion e having the deepest curve nearer the right of the rear mat. The object in so doing is to insure that water in adequate quantities will be transferred by surface tension and gravity along the gradually sloping undersurface of the plate 2d' to the downwardly curved end c and onto the water shed 26. It is less difficult to adequately supply the shed to the right of the cabinet, hence the arrangement described. Obviously, there will be a radial discharge from both discs I5 and I'l throughout the effective radius but the greater discharge will be as described and shown, i. e., towards the upper corners of the cabinet.

While not shown, it is understood that a conventional blower is disposed between the side i mats I2 and forwardly of the rear mat il to cause air to be drawn through the mats and to discharge the same at the front of the cabinet into a room or enclosure. Suction of the blower will constrain water thrown upwardly by the discs to enter the rear mat I I', saturating the same and also into the moisture collecting chambers at each side of the cabinet where the water will, in part, be influenced to enter the side mats supplementing'that precipitated by the sheds 26, as described.`

In order to control the direction of discharge as wellV as the quantity of water thrown by disc I6, a baiiie 28, consisting of a small, curved plate, so identified', is mounted adjacent the point of the greatest discharge of disc I6 and is supported adjustably by an armv 29, attached by means of screw 3Q tothe base mounting I5. It is apparent that this baille 28 may be moved towards and away' from the periphery of the disc I5 to respectively decrease and increase the quantity of water dis-` charged 'thereby' as well as to change slightly' the direction o'fdischarge. It isfuriher apparent that the confined. space in. which the disc it' is constrained to'operate',.combined with the curved bottoma ofthe cavity, limits the width of the discharge.. the said'. curved bottom' a being especially effective to establish ahead of water which remains Vconstant so long as the level in the basin is constant. v
