Stouder, Ardmore, one. Application'lti arch 15, 1935, Serial No. 11,305 l 2 Claims. (cl. 261-91) This invention relates to an air conditioner by means ofwhich air may be cleaned andcooled.

One ,object of the invention is to provide a device of this character of such construction that it may 5 be readily transported from-one part of a room or building to another and thus air in all portions of a large room conditioned, or the air in a number of rooms successively treated.

Another object of theinvention is to so form the conditioner that when it is in use, air will be drawn through an inletinto the body lportionof the device where itwill be passed through a spray of fine water particles before passing out of the device and thus dust and other foreign matter removed from the air and also the temperature 01' the air reduced by contact with the water spray. Another object of the invention is to retard outward movement 01' the air from the body by contact with a plurality of baflies whichalso serve as stop's against wln'ch moisture in the outgoing air will catch and be prevented from passing out with the cleaned and cooled air.

Another object of the invention is to provide improved means tor controlling the path of move- 5 ment of the airas it passes from the conditioner and cause the blast of cleaned and cooledair to be distributed throughout a room. r

Another object of theinvention is to provide improved means for taking up water from the lower portion of the conditioner and causing this water to be thrown upwardly in a very fine spray or fog through which the air passes and to further so mount the water sprayer that a sump may be providedbeneath' it wherein dirt in the'water will collect and thusmake frequent changing of the water not necessary.

The improved air conditioner is illustrated in the accompanying drawings, wherein Figure 1 is a'view showing the improved condi- 40 tioner' in front elevation with portions broken away. a s

Figure 2 is a sectional view taken vertically through the conditioner.

Figure 3 is a sectional view taken transversely through the upper. portion of the conditioner along the line 3 3 of Figure 2. y

'Figure 4 is a transverse sectional view taken through the lower portion of the conditioner along the line 4 -4 of Figure 2. Figure 5 is an enlarged view line 55 of Figure 2. z i This improved air conditioner has a body portion consisting of a casing which extends vertically and hasv an upper ,section I, the lower end of which telescopes into the cylindrical neck! of taken along the I a lower section 3; downward movement of the upper section into the lower section being limited by an outstanding head 4 which rests on the upper edge of the neck 2. Casters 5 are provided for the lower section at its corners in order that the 6 conditioner may be readily moved from one room to another or from one portion or a room to another in case it is-used in a large room. The upper and lower sections .are formed oi. 'any materialdesired, although strong sheet metal is 10 preferably used and walls of the lower sectionj are lined, as shown at 6, to strengthen the same and r by forming this liner of rust-proof material, rusting and ,corroding of the lower section will be prevented.

The upper section I is cylindrical in shape and of slightly less diameter than the lower section which is rectangular in cross section and this" upper section is open at its upper and lower ends but at its upper end carries a head or cover 20 formed with a depending flange which fits tightly about the walls of the upper section so that a, tight joint will be formed. The central portion of the head is cut out and the material of the head bent to vform an annular seat 8 into which 35.

is secured the upper end of a cylindrical sleeve 9. This sleeve or cylinder is 01 greater length than the upper section andwhen the upper section is in place, the lower portion extends downwardly into the converging portion III of the 30 lower section, as shown in Figure 2. As the upper end of the cylinder is firmly secured in the seat 01' the head or cover, this cylinder may be drawn outwardly by grasping the cover and exerting lifting movement. Between the cylinder and walls of the upper section there have been arranged a plurality of baflles ,or deflectors H which extend vertically, as shown in Figure 1, and are disposed radially of the cylinder and upper section, as shown in Figure 3. These bai- 40 fies maybe formed of sheet metal bent to assume the desired shape, and referring to Figure 1 it will be seen that each baflle has diagonally. extending portions I 2 which are disposed at right angles to each other. It should be further noted 45 that one end or each of the diagonally extending portions has been extended to form a lip l3. By this arrangement, tortuous passages will be defined between the bafiles and as air passes up-' wardly between these bailles, moisture in the 'air 50 'will be deposited upon'the lips and diagonally a motor 14 which is disposed vertically in the cylinder axially thereof and to the projecting lower end of the motor shaft is firmlysecured a fan I5. The motor is supported in the sleeve or cylinder bya yoke l6 having its bridge 11 extending diametrically through the sleeve and its arms. l8 extending upwardly from the bridge against walls of the sleeve. In spaced relation to the bridge the arms are bent toward each other, as shown at I9, and then upwardly to provide portions which are secured against the motor by bolts 2i, and above the motor the .arms are again bent to form flaring portions 22,

the upper ends of which are again bent'to form feet 23 overlying the seat 8. Through the seat are passed bolts or rivets which firmly secure themupon the bead, and'in order to prevent rattling noises, rubber pads 24 are tween the seat and feet. i

The yoke not only serves as a carrier for the motor, but also as a support for a shaft 25 which extends axially through the sleeve 9 with its upper end rotatably received in a bearing 26 formed midway the width of the bridge I! of the yoke. The upper end of the shaft is connected with the lower end of the motor shaft 21 by a flexible provided beconnection 28 formed of rubber tubing or any other suitable material and firmly secured about the two shafts by clamps 29. .The lower end of the shaft 25, which may be referred to as a pump shaft or sprayer shaft, is journaled in a bearing 30 which fits into an opening formed in the hub of a spider 3i, and referring to Figures 2 and 5v it will be seen that the spider is disposed in .bridging relation to an opening formed at the center of the bottom of the lower section. Be-

neath this opening is mounted a sump 32 in which dirt is to collect and in order to hold the spider in its proper position the legs of the spider are equipped with depending arms or brackets '33 carrying rubber pads 34 which frictionally engage walls ofthe sump. There have also been provided pads 35' upon the legs of the spider which rest upon the bottom of the lower section.

By this arrangement the spider will be firmly held water is necessary before the lower section of the conditioner needs to be cleaned. This watermay be of any depth desired from the bottom of the lower section to the opening but is preferably of the depth indicated in Figure 2.

This water is to be sprayed upwardly and form a fog through which air passes and in order to do so there has'been provided a pump or sprayer 38 carried by the shaft 25. This sprayer is of conical shape and has inner and outer walls 33 and 40, the upper edges of which are joined by an annular wall 4! having openings 42 formed through the outlet as clean and cooled air. As.

therein. The shaft extends through a sleeve 43 which is axially alined with the apex of the sprayer and at the top of the sprayer therehas the shaft 25 by a pin 46. It willthus be seen the temperature of the air.

manent location.

that the sprayer will be firmly secured to the shaft to rotate therewith. The lower end portion of the sprayer is immersed in the water and when the shaft and sprayer are rotated, water will pass through openings 41 formed about the apex of the outer wall and centrifugal force will cause this water to move upwardly through the space between the walls of the sprayer to the upper end thereof where it will be discharged as a spray through the openings 42 in the marginalwalls M. The fact that the'sprayer is rotating at a rapid rate of speed will cause the sprayed water to be thrown upwardly and outwardlyas very fine water drops thus forming a thick fog which fills the lower section of the air conditioner. During this operation the fan draws air inwardly through the sleeve or cylindrical column 3 and forces. the air downwardly through the sleeve to the open lower or inner end thereof where it passes into the lower section of the air conditioner. Upon entering causes dust and other foreign substances to be taken up by the water drops andv also reduce During upward movement of the air about the sleeve 3 it passes through the tortuous passages. between the baffles ii and moisture will be deposited upon the lips and end portions of these bailies. It will thus be seen that the water fog will be confined within the air conditioner and the water which will accumulate upon the baiiies and walls of the upper and lower sections will flow back into the bottom of the lower section where dirt will gravitate through the water to the bottom of the lower section and into the sump. The bailes terminate in spaced relation to the upper end of the upper section I, and above the baiiles the upper section is formed with an outlet opening surrounded by a collar or neck 43. Blades or I louvers 49 are pivotally mounted in the neck 48, as shown in Figures 2-and 3, and inner end portions of the blades carry arms or brackets 49. pivoted to a cross bar or strip .50 to cause the blades to move simultaneously about their pivots when reciprocating motion is imparted to the cross bar by a. link II extending from the outer end of a lever 52. This lever is pivoted upon a hanger 53 and'has a fork I4 at its inner end engaging the eccentric pin ll of a gear Bl meshing with a. small pinion 51 carried by the shaft of the motor and, therefore, the lever will be rocked about the hanger as a pivot to impart oscillating movement to the blades when the conditioner is in use. Since thue blades swing about their pivots of the outlet neck or mouth 48, air which passes out through this mouth will be directed toward different 'portions of a room as the blades move. .It will thus be seen that warm and dusty air in a room may be drawn into the conditioner where it is passed through a water fog to remove dust and reduce its temperature and then returned to the room the device is provided with it may be very easily moved from one of a large room to another or transferred from one room to en'- other. It will be obvious that an air condition constructed in accordance with this disclosure may be erected as an immovable device in a per- 'lower end spaced from the bottom of the casing,

a yoke in the sleeve having a bridge extending transversely across the sleeve and arms extending upwardly through the sleeve against walls thereof, the arms having their upper portions bent to converge upwardly and being then extended upwardly in spaced parallel relation to each other and then bent to diverge upwardly and having their upper ends secured at the top of the sleeve, a motor secured between the spaced parallel portions of the arms of said yoke in a vertical position with its shaft disposed axially of the sleeve, a fan carried by the motor shaft for drawing air inwardly through the inlet and forcing the air through the sleeve into the lower portion of the casing for passage upwardly about the sleeve to the outlet, a bearing at the bottom of the casing, a sprayer shaft disposed vertically with its lower end mounted in the bearing and its upper portion bridge of the yoke and connected with the shaft of the motor to rotate therewith, a sprayer carried by the sprayer shaft for spraying water upwardly in the casing and forming a water fog through which the air passes, the motor, fan,

journaled through the tion from said motor, and an sprayer shaft and sprayer being removable upwardly through the sleeve with the yoke as a unit, and means about the sleeve for extracting water from air passing upwardly about the sleeve, to the outlet.

2. An air conditioner comprising a casing having an air inlet at its top and an outlet in its upper portion, a sleeve leading from the inlet and having its lower end spaced from the bottom of the casing, means for passing air through the inlet and sleeve into the lower portion of the casing including a motor mounted vertically in the sleeve, a sprayer in the lower portion of the casing for spraying water and forming a water fog through which the air passes, means for extracting water from air as the air passes upwardly about the sleeve toward the air outlet, blades in the air outlet spaced from each other and movably mounted for directing discharge of air from the outlet, the blades being connected,

for simultaneous movement, and means for imparting movement to said blades including a bar pivotally mounted for oscillating movement and having one end portion extending into the sleeve transversely thereof and formed with forks, a gear rotatably mounted and receiving rotary moeccentric pin carried by said gear and engaged between forks of the shaft for imparting oscillating movement thereto as the gear rotates.
