' A TTORNE Y Patented Aug. 26, 1952 UNTED STATES PATENT srirroarrne AsgE This invention relates to evaporative coolers and it has particular reference to supporting fabrication designed to retain the cooler operatively in relation to a window opening.

The principal object of the invention is to reduce materially the cost for erecting supports for window coolers, especially above the ground floor and to provide internal structure which makes feasible installations of large evaporative cooler units in double hung windows without the necessity for additional external support. As a general rule, the weight of the unit is such that sub-bracing is needed, bearing against the building wall to support the cooler. Such bracing is unattractive and expensive and falls far short of providing adequate support. The invention affords a support which is not only strong and durable but of pleasing appearance.

Another object of the invention is to provide a window enclosure assembly adapted to embrace the duct through which air enters the room after penetrating the filter mats of the cooler, said assembly being adjustable to accommodate the same to windows of various widths. by virtue of a longitudinally adjustable supporting strap within and adjacent each side of the cooler and which extends from a lower outer corner thereof to the window enclosure assembly, the cooler is stabilized against lateral stresses as well as alleviating undue strain on the duct assembly. Broadly, the weight of the mass is distributed uniformly within the supportingfabrication and much of the Weight is borne by compression bolts carried by the lower support assembly of the cooler and which beara'djustably against the building wall below the window.

With the foregoing and other objects in View, the invention has further reference to certain features of accomplishment which willbecome manifest as the description proceeds, taken in connection with the accompanying drawings wherein:

Figure 1 is a vertical sectional view of a cooler shown mounted in a window.

Figure 2 is a perspectiveview of the cooler supporting assembly on a reduced scale, in which the cooler is shown in dotted lines.

Figure 3 is a longitudinal sectional view taken on line 3-3 of Figure 1.

Figure 4 is a fragmentary perspective view of the upper support, and

Figure 5 is a fragmentary detail view of one of the angular supporting strap assemblies in longitudinal section.

of the drawing, reference numeral Ill denotes the cooler housing whose side and rear walls are louvered and removable for readly access to fibrous filter mats. therein, which have been omitted from the drawing. The housing is adapted to contain a blower effective to influence air through the filter matswhich are kept saturated by waterelevated by a pumpynot shown, from the reservoir inthe bottom of the housing, in the usual'manner. ,The air is cooled by its passage through theflmats and is discharged through an opening, I I, embracedby a duct assembly [2, which latterv conveys the air into a room. Directional control of the air as it emerges fromthe duct .lZlisv accomplished by vertically and-horizontallyarranged and adjustable louvers l3... r I v The window enclosure assembly of the invention is comprised primarily of an upper support in the form of a plate 14, the'inner end of which is flanged upward at l5, and secured. by screws 16 to the inner face of .the lower window .sash frame I! which is lowered against the plate M in the manner revealed in Figure 1. 'Theplate I4 is of the samewidth as the duct l2 and its outer end is upwardly flanged at [8 and is apertured to receive bolts .19- which, extend through the front wall of the cooler housing, serving jointly to secure the plate [4 to the housing and to anchor the upper end of the supporting strap assembly, consisting of theaxially aligned straps The upper section 20 of thesupporting strap assembly is attached at its upper end to a support angle 22, the latter being secured by the bolt [9. The lower section2l of the strap assembly is secured at itslowerfend to a lower support angle 23 which extends along the bottom of the housing adjacent the rear wall thereof. Two assemblies such as. above described are required, one being adjacent each side of the housing but thesefassembli'es',lthat is, the

straps

20 and 2|, are sufficiently spaced apart to accommodate the-blower and motor, not

shown, which; are support'edon the parallel rails compensate for slight variations in relationship of companion elements of the support assembly as a whole or for minor inaccuracies in manufacture.

Mounted for lateral adjustment on the plate I4 is a pair of reinforcing angles 21 (Figs. 2 and 4). These angles are each slotted longitudinally at 28 to receive spaced apart bolts 29, anchored in the plate 14, so that the angle memher 21 may be moved inwardly or outwardly, depending upon the width of the window in which the unit is being installed. The end of each angle member is turned upwardly at 36 and secured by wood screws to the window frame, in the manner shown.

The lower supporting assembly is made up of a plate 3| below and parallel with the plate I4 of the upper support assembly and lies under the air duct l2. The inner end of the plate 31 is broken downwardly, thence forwardly at such an angle that it will lie flush against the sill 32 of the window '(Fig. l), to 'which'it is secured by wood screws 33. The plate '3l is bent intermediate its ends to .form a'vertica'l .portion 34 which bearsfiush against .the front of thehousing l .and is turned outwardly atits lower ends, thence upwardly and again outwardly, the end thereof engagingthe bottom of the cooler housing. The plate and the vertical portion 34 thereof are each provided with side flanges 35,

the inner ends of which are joined by a gusset plate 36, to reinforce the support assembly.

Theparticular manner inwhich'the lower end of the vertical portion 34 of'the .plate 3| is formed, as above described, creates a channel 3'! under the forward end of the housing I!) and is reinforced by a gusset plate 38 at each end. The flanges of this channel have aligned apertures near each end through which are passed carriage bolts 39. vA nut 40 is threaded onto each bolt against which rests a portion of the weight of the'housing since the heads 4.! of the bolts bear against the wall 42 of the "buildin underneath the window.

The full weight of the'housing 1-0 is distributed between the upper and lower supports, the upper support together .with the supporting strap assembly, being under tension while the bolts 39 are under compression, as imposed throughthe lower support.

After the upper support is installed as described, the housing is elevated into position so that duct vI 2 will be disposed in the window opening. The side reinforcingangles 21 are set "into position after first centering the duct with respect to the window. .Theiower'supportis positioned so thatthe inner edge of the plate 3| will bear againstthe window stool and is secured by the screws .33. The window sash frame I; is brought down against :thetop of'the duct l2 and the upturned .flange of plate 14 is secured to the sash frame by screws 16.

A spirit level isfplacedon the housing It! and adjustment is made in the length of the strap assembly 2l until the housing is made level. At the same time,thejnuts on the compression bolts 39 are moved "to insure that these bolts assume at least apart of "the load with the housing In in a level position in order to relieve undue strain on the window sash frame l7.

It is obvious that any adjustments interiorly of the cooler housing-maybe made from within the room, which is a desideratum when the cooler is installed in windows above the ground floor. After installation and following any required adjustments, the louver assembly I3 is installed along with side extension panels 42, which are mounted vertically behind the window sill and sash frame (Fig. 2) on each side of the duct l2 to close the space not occupied by the duct.

Manifestly, the construction as shown and described .is capable of some modification and such modification as may be construed to fall within the scope and meaning of the appended claims is also considered to be within the spirit and intent of the invention.
