AXE WASHER.

Application filed November 3, 1923. Serial lllmdlddhd.

or" Chicago, in the county of Cook and State of Illinois, have invented certain new and useful provemen-ts in Air Washers, of which the following is a specification.

My present invention embodies improve ments in air washers over that set forth in my co-pending application for Letters Patent for improvements in air washers, Serial No. 623,830, filed March 9, 1923, and like the invention disclosed in my said application, relates generally to improvements in air moistening, dehumidifying and purify apparatus.

ln 3, general way, the object of my present invention is substantially the same as that set forth in the aforesaid pending application, to wit: the production of an apparatus of the above named general character, which shall be simple and mexpensive in construction, compact in form, and highly eflicient in operation, wherein and whereby a continu one current or volume of air, which may or may not previously or afterwards, have its temperature raised'or lowered, is beneficially treated and caused to flow through a conduit or casing and be delivered to a suitable place or places for any desired purpose.

Specifically, my present invention is directed to an improved construction and arrangements of arts over the structure and arrangement of the parts of the aforesaid pending application, whereby the capacity of the apparatus will be greatly auented over that of my aforesaid invention, or,

in other words, a greater quantity of air can be treated by the apparatus embodying the resent invention and more efiiciently than y the apparatus disclosed in my Said application, without unduly increasing the dimen sions of the parts of the device.

l accomplish the last named objects or results by an improved construction of the moisture eliminating element of the invention as well as by the arrangement and construction of certain arts of the device which cooperate with sai elements. v

The invention consists in certain peculiarities of the construction, novel arrangement and combination otthe various parts thereof, as will be more readily elained and understood when read in. conjunction with the ancornpanyin drawin in which an 'l llll lz oi wich the invention is susthat changes and modifications ma ceptible is illustrated, it being understood be resorted to without departing from t e spirit of the invention so 10 the scope of the appen ed claims.

orresponding numerals of reference refor to like parts throughout the diilerent views of the-drawings.

'lhe conduit or casing of the device is designated as a whole by the numeral 10 and is herein shown as being rectangular in cross-section and of an elongated shape. This casing may be made of any suitable size and material but by preference of sheet metal and has its inlet end open from its top to a the.

point at a desired distance above its bottomor floor as at 10, see Fig. l of the drawings. By terminating the opening in the trout end of the casing at. a distance above the bottom thereof, it is apparent that a compartment for holding water 11 will he provided at the lower portion of the casing. charging end of the casing is provided with an inwardly extended" flange 12, the free edge of which forms an opening 13 for communication with a blower casin. designated as a whole by the numeral it w ich may be suitably mounted on the end of the we ing it) but for communication therewith as above its will be observed in 1 ol the drawings, the casing to is provided rearwardly all lllll The llll

its longitudinal middle with a transverse partition 15, thereby dividing the casing 10 into two chambers or compartments 16 and 17, the latter being of less depth than the former or front compartment and has its floor forwardly and downwardly inclined from the front portion of the blower casing 14 as at 18, see Fig. 1, to the rear wall of the compartment 16 to which said floor is secured at a point a suitable distance above the floor of the chamber 16 for the purpose to be presently explained.

Just above the floor 18 and at the front edge thereof, the partition 15\is provided with one or more openings 19 for the passage of water from the inclined floor 18.to the container 20 for water in the lower portion of the chamber 16, which container has vertically mounted therein at about its middle an overflow pipe 21 for the discharge of water when a suflicient quantity thereof has accumulated in the container 20 to enter the upper end of said pipe.

Transversely journaled in the blower casing 14 and'extended through the casing 10 is a rotary shaft 22 which is journaled at its end opposite the blower casing 14: on the upper portion of a standard 23 which may be supported on the floor of the chamber '16 of said casing. This shaft may be driven by any suitable means but in the present instance is shown as being equipped at its end adjacent the blower casing 14 with a pulley 24 to which a belt may be applied for transmitting power thereto from any suitable source.

Mounted on the shaft in the blower casing is a fan 25 of any preferred construction, which is employed to create and maintain a current or volume of air through the conduit orcasing of the apparatus and to forcesaid current through an outlet 26 of the blower casing, from whence it may be conducted to any suitable place or places and used for the desired purpose.

One of my improved water or moisture eliminating elements is mounted in the compartment 16 of the casing and comprises a hub 27 secured to the shaft 22 so as to ro- -tate therewith and having a series of blades or vanes 28 radially extended therefrom and set at angles diagonall' disposed with respect to the shaft 22, is employed for removing moisture and impurities from the a rearward annular extension 30 which closely surrounds yet without contacting therewith, a forwardly extended annular flange 31 on the front surface of the partition 15, which flange surrounds an opening of its size in thesaid partition as will be readily understood by reference to Fig. 1 of the drawing, in which View it will be seen that the rear edges of the outer p01" tions of the blades 28 terminate short of the rear end or edge of the rim 29, or in other words, are located just in front of the front edge of the flange 31 carried by the transverse and vertical partition-15. Mounted on'the inner surface of the rim 29 at the rear edges of the blades 28, is an annular cleat or bafiie member 32 which is inclined forwardly as is clearly shown in F igs.,1.and 4 of the drawings whereby an angular trough-like structure will be provided around the inner periphery of the rim 29 just forwardly of the front end of the flange or annulus 31. On that side of each blade 28 adjacent the cleat or baiiie member 32 a series of spaced fins or ribs 33 are longitudinally secured in such a way as to have a slight inclination towards the member 32 yet so -as to be disposed at acute angles to the surface of the blade 28 on which they are mounted, these acute angles bein located on that side of the members 33 a jacent the front end of the rim 29 of the eliminator wheel. Mounted on the opposite surface of each of the blades 28 and longitudinally thereof are a series of spaced fins or ribs 34 which are disposed at substantially right angles to the front edge or end of the member 32 yet so as to form acute angles between said members 34 and the adjacent surface of the blade 28 on which they are mounted. The above named construction is clearly shown in Fig. 4, in which view it will be observed that the adjacent edges of the members 33 and 34 are so disposed and secured to the blade 28 as to form corners of rectangular figures when viewed in cross-section. At the apex of each of these figures the rim 29.is provided with an opening 35 each of which openings is of sufficient size to be common to the angular spaces on each side of the blade 28 or in other words of suchsize as to provide an outlet through the .rim 29 on each side of said blade.

As shown'in Fig. 3, the fins or ribs 34 of each blade 28 are spaced substantially in parallelism with one another and on account of the fan shape of the blades 28, the intermediate ribs or fins are consecutively shortened so that they can be thus positioned on the blades. The same arrangement is carried outwith reference to the fins or ribs 33 on the opposite side of each blade.

Mounted on suitable brackets 36 extended upwardly from the floor of the chamber 17 of the casin 10 is a cone-shaped water eliminating e ement 37 which is by preference hollow and made of sheet metal. This cone-shaped member surrounds the shaft 22 concentrically as shown in Fig. 1 directly in front of the opening 13 in the flan e 12 of the rear end of the casing 10 an has its front tapered end located at the rear end of the flange 31 and concentrically therewith. The member 37 has at its enlarged upper rear portion an outwardly and forwardly disposed flange 38 located eccentrically with res ect to the axis of the member 37 as wil be readily understood by reference to Fig. 2 of the drawing. The lower portion of the coneshaped member 37 is provided at its rear edge with a forwardly and inwardly extended flange 39, which flange, together with the lower rear portion of the member 37, forms a trough-like receptacle for the collection and guidance of water collected by the flange 38 and the upper side portions of the flange 39. Communicating at one of its ends with the trough or receptacle provided by the flange 39 is a pipe 40 which 15 extended at its other end through the opening 19 in the partition 15 just above the floor 18 of the rear chamber of the conduit or casing. This pipe 40 also extends through an openin in a baffle 41 located on the floor 18 of t ierear chamber of the casin rearwardly of the partition 15 and said afie is employed to prevent water discharged by the pipe 40 being forced back into the said chamber.

Mounted on the shaft 22 near its front end, is a spraying wheel which is quite similar to the spraying wheel shown and described in my aforesaid pending application, and is designated as a whole iy the numeral 42 and comprises a hub 43 which may be fixed to the shaft 22 so as to rotate therewith, by any suitable means. Extended radially but forwardly from the hub, or rather towards the inlet end of the casing orconduit, are a lurality of spaced spokes 44 which are united at their outer portions by a band 45 which has the same inclination as the spokes 44 and is provided on its inner surface with a series of diagonally disposed spaced blades 46, (see Fig. 5) which extend inwardly from the band 45 and forwardly thereof towards the inlet end of the conduit or casing as is clearly shown in Fig. 1 of the drawing. The inner edges of the blades 46 terminate a distance from the shaft 22 and it will be understood from the above description that the spraying wheel is of an overhanging type. .Mounted around the shaft 22 preferably within the space provided by the overhang ing blades 46 of the spraying wheel, is a water distributing or ejecting member 47 which is preferably in the form of a tubular ring and has in its outer periphery a series of small perforations 48 for the discharge of water from said ring or member. This water distributor or ejector is supported in a fixed position around the shaft. 22 but independently of its movement by means of a water supply pipe 49 which has communication through one of its ends, with the member 47 and at its other end with a supply of water under pressure not shown. This supply pipe may be sup ported on the standard 23 which supports one end of the shaft 22 by being extended through a suitable opening in the upper end of said standard.

The operation of the device is as follows:The shaft 22 carrying the fan 25 and the rotary eliminator so as to rotate with said shaft, is driven as before stated. by power applied through any suitable means but usually by means of a belt supplied to the pulley 24 on said shaft. The rapid rotation of the fan and rotary eliminator will create and maintain a continuous current of air entering the inlet end of the conduit, through the same, and said conduit will be dischar ed from the fan casing 14 through its outlet 26 from whence it may be conducted to any suitable point or places. In this operation it is evident that the spraying wheel 42 will also be rapidly rotated by means of the said shaft. Now, assuming that a supply of water under pressure is admitted to the water distributing or ejecting member 47. it is manifest that it will be forced through said distributor in radially disposed jets or small streams with which the blades 46 of the spraying wheel will contact and act to force the water in spray or mist-like condition circularly at the inlet end of the casing or conduit As the blades 46 of the spraying wheel 42 areydiagonally disposed on the inner surface of the band 45, which band is flared towards the inlet end of the easing, the water will be more effectually driven forwardly by the action of said wheel than if the said bladeswere located radially on said band, as in my above named application. The current of air passing into the conduit will be subjected to theispray or mist-like sheet of water created by the rapidly rotating spraying wheel 42, and will absorb a quantity of the same. In the further progress through the casing of the air, it will contact with the rotating blades 28 and the fins 33 and 34- on opposite sides pf each of said blades and through centrifugal action, the water and impurities will be forced outwardly along the surfaces of the blades 28 and adjacent surfaces of the fins or ribs 33 and 34 until the rim 29 of the wheel is reached, from whence they will pass through the openings 35 therein and be discharged into the chamber 16 and precipitate into the water container 20 of said chamber.

- After the air has been subjected to the action of the blades 28 and their fins or ribs, the current thereof will pass through the opening provided by the flange 31 in the partition 15 and impinge against the coneshaped water eliminator 37 on which it will travel rearwardly and outwardly from the tapered portion of said member until it strikes the flanges 38 and 39, from which it will pass around the enlarged end of the coneshaped eliminator and rearwardly out through the opening 13 in the rear end of the casing and from thence into the fan from which it will be discharged through the outlet of the latter. In this operation of the current of air on the cone-shaped eliminator, it is manifestthat moisture or water contained therein will be extracted therefrom and caused to collect in the trough-like portions provided by the flanges 38 and 39, from the latter of which the water will be. drained through the pipe 40 into .mounted on and to rotate with said shaft within said casing said wheel comprising a plurality of spaced radial blades each set at an angle to its axis and provided with a peripheral rim connecting the outer ends of said blades, the said rim having a plurality of spaced openings arranged in a row at the outer end of each of said blades, said openings being of sufiicient size as to each afford outlets on opposite sides of each of said blades, a plurality of spaced fins longitudinallymounted on each surface of each of said blades and connected at their outer ends to the inner surface of said rim, the said fins being disposed at acute angles in the direction of the rotation of the wheel with respect to their blades and connected to the same in pairs at the rear portion of each of said openings in the rim, and a forwardly inclined annular cleat or baflle member secured to the inner surface of said rim at the rear outer portions of said blades, said rim having a series of spaced open-o ings at the adjacent edge of said baflle.

2. An air washer including a casing for the passage of air and a. rotatable shaft located longitudinally therein means in communicationv with an end for creating and maintaining a current of air through the casin an imperforate cone-shaped moisture e iminatin member fixedly mounted within said casi in front of its disdischarge opening wit its tapered end disposed forwardli of said casing, said member having at t e upper rear portion of its periphery a forwardly and outwardly extended fiangle and at the rear lower portion of its peri cry a forwardly and inwardly extended ange forming a trough-like receptacle on said last named ortion of said member, and a ipe extend at one of its ends through t e last named flange for draining water therefrom.
