" Be it known that l, WILLIAM MAXWELL REED, a citizen of the vUnited States, residing at Louisville, State of Kentucky, have invented certain new anduseful Improvements in Air-Cleansing Devices and ventilators;
and l do hereby declare the following to be rooms or chambers wherein it is desired to ventilate the Sameand maintain a circulation of air therethrough, entirely free from dust, dirt or other foreign matter or impurities.
- Primarily, the device' is adapted to be in- Y stalled in a drying or finishing room comair therein is not constantly changed, the
same, within a short time, will become so damp and humid that it will not take up any more moisture, and, consequently, the drying process will come to a standstill, the
Y articles thereinbecoming more or less sticky, resulting in a loss ofthe gloss and lusterre-v quired of the finished article. Furthermore,
the air will. become so saturated with turpentine as to make it practically impossible for the employees to work in the room, and in some instances the ,turpentine and similar vapors will have an injurious effecten the l5 l through the drying process.
paintl and varnish on. the articles being p'u The principal object of thisinvention is to provide a device of the character indicated that will overcome the various disadvantages above noted, whereby the air is' drawn into and 'forcedI through the drying room, thus maintaining a circulation of air at all times, wmeans being provided for previously extracting all dust/'and dirt from the 'air just priorv l l view, showing the manner of positioning the lll@ to its entrance into the room.,

application led January it, i921. serial ivo. 437,182.
Anotherbject ofthe invention is the pro- I vision of an arrangement of this description which will be simple in operation and construction, cheap to manufacture, and one that `by reason of its unitary construction can be adapted to and used in connection with the Ventilating of'various plants, such as dynamo rooms, pu lic halls, and other 'places where a contin yous supply of clean fresh air is desired.v v
As hereinbefore stated, it is not only necessary that vthe air inthe drying room be renewed and a circulation maintained, buty it should also be cleansed of all foreign particles, such as dirt and the like,'and the invention. further 4 contemplates a means whereby this may be accomplished in a` simple manner, as the air is being drawn into the room, the details of which arrangement will 7E be hereinafter more" fully described.
Generally stated, the invention comprises anair cleaning and suction device, preferably positioned at an opening in lone wall of a drying room, or similar chamber, whereby air isvdrawn into the lroom and'caused to .circulate therethrough, passing out of ancomprises, preferably, a casing of square funnel shape, having its, big end closelypositioned in the opening formed in one of the walls of the room, and its small end supported upon uprights or standards, said' big end being inclosed by a frame supporting a series of narrow trays positioned between a pair of spaced wire mesh screens 'through' which the air is drawn by a suction fan mounted in the small orreduced end of the device..4 ln the space between-the vscreens and trays is a lilling of steel wool or similar reviously saturated with oil, which, having an attraction for dirt and the like, extracts uall dust and foreign particles from thev air passing therethrough intothe drying room, theftrays merely acting as drip -pans to catch the excess oil that percolates down through the saturated material.
The preferred embodiment of the invention is illustrated in the accompanying drawin s,. in whichv y ig. 1 1s a diagrammatic, fragmentary device with respect to the drying chamber.
gri
Fig. 2 is a rear vieviT of said device, showing the means of supporting the inner end vo eration of the ventilatinoarrangement.
Upon referring to l of the drawings, it will bel noted that the large end of the funnel-shaped casing is adjusted to and supported within the opening of the chamber 3, and the small end thereof, which projects inwardly of the chamber, is supported upon standards 5, provided with a supporting base 6 adapted to rest upon the floor of said chamber. This is the preferred form of support, but obviously any other means of bracing or supporting this inner end may be employed, to suit the various conditions and locations where it might be -found necessary to locate the device with respect to the drying chamber.
'llhe air cleansing and Ventilating device per se, it will be noted upon referring to the enlarged detailed views in Figs. 3 and 4C, is, as hereinbefore stated, of square funnel shape, the hollow casing 1 preferably of sheet metal havingan enlarged square end and a reduced end portion terminating in an annular extension? in which is adapted to be mounted a fan 8, preferably of the electric type, and suitably connected with the necessary source of power for operating said fan, which fan provides the means of constantly furnishing a fresh supply of air to the drying chamber and causing the continuous circulation thereof througi the drying chamber.
ln order to extract all dirt and other'foreign matter from the air before entering the drying room and to insure the entrance of only clean air thereinto, the 'enlarged or outer end of the casing 1 is supplied with a 1 frame 9 provided on its opposite side faces.
with a pair of spaced Wire mesh screens 10 and 11, the frame 9 being of sufiicient depth to permit the desired spacing of the screens 10 and 11. `Within the inclosure formed by the frame 9 and screens 10 and 11 is confined a filling or air filtering medium of steel Wool or similar material 12,l which has previously been saturated with oil or the like, and through which material the air is drawn by the fan 8 during the operationof the device,
aiiinity for dirt and other extraneous substances, the saturation ofthe air filtering material withoil, and used in the particular arrangement hereinbefore described, provides a very simple and emcient means of cleansing the air as it is drawn through the casing 1 and forced into the drying room or chamber by the fan provided for the purpose. in order to prevent the leakage of oil, which would obviously percolate down through the porous filtering material, 'there is provided a series of transversely arranged pans or trays 13, which pans are supported within the frame 9 and also inclosed between the screens 10 and 11, as clearly shown in Figs'. 3 and it. These trays will also prevent the settiing orpacking down of the nltering material as they form substantially a multiplicity of small compartments within the screens and frame.
in order to renew the filtering material when desired, and also replenish the supply of oil when necessary, the outside screen 11 is detachably secured to the frame 9 by a removable frame 14,' as clearly shown in if ig. 4. This outside screen 11 is also made detachable for the purpose of obtaining access to the pans or trays 13 and permitting the removing therefrom, when necessary, the accumulated oil at predetermined periods, which oil is obviously saturatedwith dirtand other substances extracted from the air .during its passage through the cleansing medium.
' Although the invention has been illustrated and described with particular reference to drying rooms, chambers and the like, the same is not to be so limited, as obviously the arrangement and particular apparatus is equally well adapted for the ventilation of various plants, dynamo rooms, public halls, and similar places where 'a continuous circulation and supply of clean, fresh air is desired.
What I claim is:
1. A device of the character described comprising a-frame open at the front and rear, a plurality of horizontally disposed partitions extending transversely of the frame, a screen secured over each open face of said frame, anda filling of air-filtering material confined within the frame upon said partitions and between said screens.
2. ln'an air Ventilating and circulating device,adapted for use in connection with drying rooms, chambers and the like, the combination with a fan, of a tubular casing adapted to be positioned in an opening in said room .or chamber, a frame having transverse partitions positioned Within the casing, a screen Secured to each side face of said frame, and a filling of air filtering material confined within the frame upon said partitions and between said screens.
3: In an 'air ventilatingand circulating device, adapted for use in connection with drying rooms, chambers and the like, the combination with a fan, of a tubular casing adapted to be positioned in an opening in said room or chamber, a frame positioned Within said casing, a screen secured to each side face of said frame, and a series of pans and a filling of air filtering material confined within the frame and between said screens.
' 4. In an air filtering or circulating device, the combination with a drying room, cham ber or the like, of a funnel shaped tubular casing adapted to have its large end po.si'
tioned in an opening in the Wall of said room-or chamber, means for supporting its opposite end, a frame positioned in said large end of the funnel shaped casing, a screen secured to .each side face of said frame, a series of pans and a filling of oil saturated filtering material confined Within the frame and between said screens, and a fan mounted in the small end of the funnel shaped casing for drawing the air therethrough and through the filtering material and forcing the same through and out of the drying room or chamber.
5. A ventilator comprising a casing open at both ends, a fan-disposed Within one end of the casing', a frame rsecured to the opposlte end of the casing, a plurality of horizontally arranged pans supported in the f frame, sheets of absorbent material saturated frame to hold the absorbent sheets in place and to filter the air passing' therethrough.
6. A ventilator comprising a casing open at both ends, a frame mounted in one end of the casing, a plurality of horizontally f disposed pans supported in the frame, sheets of absorbent material saturated With liquid supported in the pans, the latter serving to catch any liquid that may flow from the absorbent sheets, and reticulated sheets secured to the opposite faces of the frame to lhold the absorbent sheets in place land to filter the air passing therethrough.
\7. A device of the character described comprising a frame, a plurality of horizontally disposed troughs supported in the `\frame, one above the other, Wads of absorbent material supported by the troughs and extending from one end' of the latter to the other and also reaching from one trough to the other, and reticulated sheets removably secured to the opposite faces of the frame.
In `testimony whereof I affix my signature.
