Patented Aug. 30, 1938 UNITED STATES PATENT oFFicE . 2,128,878 WATER _ELIMINATOR FOR CO0LING Waldo ltr-Kell, Kansas City, Mo., assignor to The Marley Company, Kansas City, Mo., a corpo ration of Missouri . Application september 15, 1937, serial No. 164,003 s emma.' (ci. lss-_15) This invention relates to water eliminators'for use at the top of cooling towers and has for its general object to produce an eliminator assembled lin sections or units‘of a plurality of'serpentine 5 or zigzag passageways, so- that the eliminators may be placed in or removed from operative po sition for repair or other purposes, without neces sitating the services of a carpenter or other ex terial. Each pair of spaced bars I-2 is, by preference, provided with stop or connecting por tions 3 at their angles, for a purpose which will hereinafter appear. ' In the drawing, the plate-like members, which pert workman. 10 more or less loosely receive in threaded relation louver boards or slats, as by 'providing pairs of spaced bars I and 2, or, of course, the passage-ways might be cut or punched out of sheet ma Another object of the invention is to produce a construction in which the louver slats or boards are in threaded relation to spacers and supports. ,and are more or less loosely held in position, since it has been found that this permits the boards to accommodate themselves to warping with the result that there is less breaking, split ting or crackingof the boards and their lives are materially prolonged. A further object of the invention- is to produce 20 an eliminator which does not depend on the for convenience may be referred to as grills, are 10 so formed that each pair of bars I-2 are con nected to adjacent pairs of bars by end pieces 4. In the construction shown the grills are of such length and width respectively, as to provide eliminator units capable of receiving in threaded 15 relation seven rows of slats or louver boards i arranged three deep or on three diiîerent levels, thus providing two breaks or changes in the di rection of air currents passing up through the eliminator. The proportions of parts` is such that strength of driven or threaded metal parts for its each slat is more or less loosely held to permit it to warp or move slightly along its entire length, life, since it has been found that wooden elimi nators as at present constructed, have a life _since it has been found that if such a slat is rigidly held at a plurality of points, it quickly limited by the fastening means employed. A still further object of the invention -is to splits and cracks in the endeavor to accommodate provide an eliminator of such nature that the ~ itself to the unequal strains set up by the warping turbulence of the air passing out through the of the boards in service. Of course, the grill units may be made to provide a larger number of rows eliminator is increased, thus inducing more com f plete deposition of moisture before the air exits in either depth or in numbers countedv horizontal 30 through the top of the labyrinth, this object being ly, if desired. Each grill, if made as here shown. accomplished by a spacing of the boards or slats is formed with male and female ends for inter locking engagement with adjacent grills. as will hereinafter appear. With the general objects named in view, and The pairs of bars |--2 are spaced apart such others as will hereinafter appear, the invention distances that air passing up _between the slats 5 35 consists in certain novel and useful features of . must change its direction of travel as previously construction and combinations of parts as herein mentioned. thus causing the air to deposit its ' after described and claimed; and in order that it moisture on the inclined faces of the louver slats. may be fully understood, reference is to be had to the accompanying drawing, in which: In the preferred construction, the edges of ad jacent louver boards or slats I are spaced apart by the stops I. and although this construction has 40 Figure 1 is a top plan view of an eliminator embodying the invention. ' Figure 2 'is an enlarged cross-section through a portion of the eliminator as shown in Figure 1. Figure 3 is an enlarged perspective view of one 45 end of an eliminator slat-supporting grill member. Figure 4 is a section through the upper end of a cooling tower taken longitudinally of the water eliminator bridging the tower. In the drawing, where like reference characters 50 identify corresponding parts in all of the figures, a plate-like member, which may be of anydesired material, guage orv thickness, length and width, as will hereinafter more particularly appear, is formed to provide a plurality of serpentine or zig-zag cross passageways of lsuch width as to - been found non-essential, it is desirable as it in creases the turbulence of air passing through the eliminator and thereby increases the deposition of moisture.y With a construction embodying the invention the louver slats 5 may be assembled in threaded loose relation with 'the desired number of grills, depending on the lengths of the slats which is de termined by the span to be bridged or the width of the cooling tower. In the construction shown in Figure l, four grills are illustrated in support ing and spacing relation with each span or section of the eliminator. In practice, it has been found that by providing shelves or supporting surfaces 6 at the top of a cooling tower 1 and placing the 55 _ y a,1as,eve - endmm mus adjacente ma shelves to atmen ' the ends o! the louverslats. each unit of the slats and out of direct contact tower structure. l _ A eliminator may be placed in-position on the 2.Acoollngtowerhavin_gsnopenupperend ' shelves without necessitating of employing secur y ing or hold-down means of any kind as the weight and provided along two of its opposite sides with _supporting shoulders, said open end of the tower being closed by a water eliminator »comprising s ` o! each section is distributed over the ends of all v l - o! the slats of the lowermost row.
