EVAPORATIVE COOLERS Filed May 11, 1961 INV ENT OR James D. C016 1 ATTORNEYS United States Patent Oflice 3,165,510 Patented Jan. 19, I965 3,166,610 EVAPQRATHVE tCGULERS James D. Cole, Austin, Tex., assignor to Myers K. Parsons, Austin, Tex. Filed May 11, 1961, Ser. No. 109,306 1 Claim. (til. 26129) This invention relates to evaporative coolers in which the air which is drawn into the casing is forced upwardly thereof through a curved duct and from thence into the room, and the principal object thereof is to provide mounting means at the bottom of the duct for position ing with respect thereto a fan blade operated by an electric motor which is supported by the duct itself in fixed relation, thereby greatly adding to the efliciency of the evaporative cooler.
Other minor objects of the invention will be hereinafter set forth.
I will explain the invention with respect to the accompanying drawing which illustrates one practical embodiment thereof, to enable others to adopt and use the same, and will summarize in the claim the novel features of construction, for which protection is desired.
In said drawing:
FIG. 1 is a perspective view of an evaporative cooler embodying my invention.
FIG. 2 is a transverse section through the cooler, taken on the line 2-2, FIG. 3.
FIG. 3 is a vertical section through the cooler showing the internal arrangement of parts therein, particularly the motor and fan mounting arrangement.
As shown in the drawing, my novel evaporative cooler comprises a rectangular casing 1 having in its face In a rectangular opening 1]) through which extends the outer upper end 2a of a duct 2 from which the air is forced into the room, the outer end being formed if desired with louvers or shutters 3 to direct or control the volume and duration of air delivered by the cooler.
In the face 1c of easing 1 air inlet openings in the form of louvres 1d (FIG. 1) are provided, and preferably the louvres are backed by evaporator cooling pads 1e (FIG. 2) in the usual manner. However, the details of the louvres 1d and evaporator cooling pads 1e form no part of my present invention.
The duct 2 curves downwardly within the casing 1 and its lower end 20 is open and forms a duct inlet disposed horizontally as distinguished from the vertical outlet end 2a, the lower end of the duct 2 terminating at approximately the middle of easing 1.
Disposed adjacent but below the duct inlet 2c is a bladed fan or air propeller 4 which is mounted upon the shaft of an electric motor 5 which motor has a casing preferably of circular shape. The motor 5 is removably supported at the lower end of the duct 2 by means of opposed straps 6 which have their upper and lower ends flattened and provided with holes for the reception of screws '7 or the like, the straps 6 being disposed vertically within the casing, and being disposed at diametrically opposite sides of motor 5.
At the lower end of each strap 6 is one member of a split clamp 8 which is secured by the screws 7a or the like to their respective straps 6 at the lower ends thereof, each split clamp having flanges 8a at its ends which are adapted to substantially abut and are drawn together by screws 9 or the like to securely clamp the casing of motor 5 therebetween, thereby securely mounting the motor 5 on the duct 2 itself.
The bottom of the casing 1 forms a water sump 13, and on the bottom of the casing 1 is an electrically driven water recirculating pump 14, which pump 14 may be connected to a water distributor duct or pipes 15 terminating adjacent the top of the casing at the interior thereof. Electric wires for the fan motor and the pump motor respectively may extend through a suitable electric wire harness 16, and the wiring may include a capacitor 17.
The above construction involving the use of the curved duct with the fan motor directly mounted thereon at the inlet end thereof provides a very efficient means for delivering large quantities of cool air at the lowest noise level, and the arrangement greatly adds to the efficiency of the evaporative cooler, and provides a construction or arrangement which will produce a greater c.f.m. due to the specifically designed arrangement.
I do not limit my invention to the exact form shown in the drawing, for obviously changes may be made therein within the scope of the claim.
I claim:
In an evaporative cooler provided with a rectangular casing having an air inlet in one side thereof and evaporative cooling pad means therein, and having a rectangular opening in another side thereof, a fan-duct assembly within and spaced from the walls of said casing consisting of an arcuate-shaped duct of rectangular cross-section having its air inlet end disposed horizontally adjacent the mid-height of the casing and having its outlet end extending through the casing opening and disposed vertically of the casing; means for mounting the duct in spaced relation within the casing; a pair of vertically disposed straps mounted on the air inlet end of the duct and extending below said end; a pair of split clamps disposed horizontally and mounted on the lower ends of the pair of straps respectively; a motor having a casing secured by said split clamps and having a vertically disposed shaft; a fan on said shaft between the air inlet end of the duct and the motor casing for directing the air upwardly onto the curved surface of the duct and out through the air outlet end thereof; and means for drawing the split clamp members together around the motor casing.
