, Appli catic niu Q 1: .My} inventionrelates to V improvements m retion'iappa ratus for cleaning rooms particularly in 'inhabitedbuildings. V y o L I @The'primary obiect of my invention is to'pro- Vide suctionfapparatus for conveying dir tgdust and thelike from rooms being cleaned in .a building to. the outside; of the building, separating and collecting thedust and dirt from the airsucked out of ther s, filterin t e ir to r m ve odors and dust therefrom'and discharging the filtered odorless air outside the building. f

flnother object is to provide an apparatus of the character and forthe purpose above setforth adapted for silentoperation, low cost or installation and operation, and for use therewith and';-

quick easyattachment thereto of suction cleaning implements in the rooms, such as nozzles obviating handling of the usual heavy and cumbersome vacuum cleaners.

Other and subordinate objects, within the pur- 1 panyingiand forming part of this specification.

In said drawings: I

Figure 1 is a fragmentary view in vertical section, partly in elevation; of my improved suction apparatus installed in connection with a building and connected to a room therein;

Figure 2 is a fragmentary view in elevation of the suction tubing;

Figure 3 is a view in vertical section partly in elevation of the combined suction producing, dirt collecting, and air filtering unit, drawn to a larger scale;

Figure 4 is a view in horizontal section taken on the line 44 in Figure 3;

Figure 5 is a view in horizontal section taken on the line 5-5 of Figure 3.

Referring to the drawings by numerals, according to my invention, a suction line of tubing I is installed, substantially horizontally, beneath the main floor 2 of a building 13, for instance in the cellar 3. The tubing I is provided with vertical branches to the various rooms of the biulding, one of which, designated 4, is shown. as suflicient for the present purposes, and which extends upwardly to a floor socket 5 in the room 6, preferably adjacent a wall I. The floor socket 5 is of the conventional type for coupling thereto an end of a flexible nozzle implement, not shown, for suction cleaning in the room.

The suction tubing l is preferably formed of sections 8 connected together by the usual cou- SUCTIONAPPARATUS-FOR CLEANING oMs Y j Harold F. Ja'cks ongLong Beach; Califlassignor of "Qone-third to William L. Hildebrand, and, one- Robert Whitehead, Long"B each,

The suction tubing extends out of the outside or'icellar wall" l0 and is coupled,as at H to .the intakenipple l2 of a combined suction produc mg; dirt collecting and airy filtering unit 13 located outside the building 3, preferably close thereto, and in a suitablecabinet I {for protects ingithe same and provided with a hinged top' door I 5 for access to the unit l3. The combined .suctionproducing, dirt collect; ing and' air filtering unit l3hcomp-rises'f a fcyline drical casing I 6, of any suitable metal, open at its bottom andhaving an upwardly taperingtop section I! to which the nipple is suitably fixed and which is formed with an annular dished top seat I8 for a purpose presently explained" if A relatively smaller-diameter, down Ttake flue (9 depends into" the casing l6 concentrically thereof with a flaring upper end suitably fixed to said casing 16 at the bottom of the top section H. The lower end of, the down take flue i9 is spaced ,from the bottom of-the casing l 6 for a purpose presently apparent. A cylindrical pan 2| is fitted over the bottom of the casing is and detachably attached thereto by suitable nut equipped bolts 22 hinged to said pan, as at 23, to be swung-upwardly into keeper lugs 24 suitably mounted. on the casing I6. The pan 2| closes and seals the bottom of the casing Hi to hold water 25 in the bottom of said casing and in said pan, and into which the lower end of the down take flue I9 is partly submerged. Above the level of the water 25, the down take flue l9 and the casing I6 form an annular up take chamber 26 in the casing l6 and around said duct I 9 communicating at its upper end with v upper, screened, air discharge openings 21 provided in said casing [6.

An annular, downwardly tapering deflecting member 28 is fitted horizontally and suitably fixed at its upper edge in the top section I! 'of the casing l6 above the down take flue l9 and the nipple l2, and which forms with the upper end 20 of the down take flue I 9 a downwardly converging, annular suction channel 29 at the upper end of said flue I9 into which the nipple l2 discharges.

A motor 30 is suitably seated at one end in the seat I8 with the armature shaft 3| thereof depending through said member 28 and suitably down draft in the down take flue IS. The motor the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claims.

Having described the invention, what is claimed as new is: 1. A .combined, dirt collecting andairj' filtering device for cleaning a room comprising a casing having a bottom water containing receptacle for 30 may be energized from the usual building circuit, not shown, and controlled from within theroom 4 by any suitable means.

Suitable brackets

34, 35, bolted, as at36, to the cabinet l4 and to the wall In suspend the motor 30 and the casing IS in the cabinet 14.

The manner in which the described invention operates will be readily understood. With the motor running, suction is created in the-suction tubing l to draw dirt and dust from the socket end of said tubing into the suction channel 29 from which the dirt, dust and air therewith will be blowndownwardly through the down I take jflue ISVinto the water 25. The dust, dirt and like matter settle in the lower end; of ,the'casing'lG onthe pan 2| and is thereby separated from the air which passes upwardly through the water 25 and isfiltered to remove odors therefrom. The filtered and cleaned air ascends through. the uptake chamber 26 to be blown free of odors and dust out of the discharge openings 21in the cabinet L4. With the door [5 of the cabinet M'open, the cleaned and purified air escapes to the atmosphere outside the building. Thepan 2! can be detached, in a manner which will be clear, knocked downwardly off the bottom of the casing l6. and removed through a small hinged door 31, in the cabinet M for disposal of dirt and dust collected therein at will.

As w'illnow be seen, the cleaning of the room 4 is accomplished substantially noiselessly, without vibration, or lifting of heavy vacuum cleaning equipment. The apparatus is economical to install because it is simple in construction and the entire unit I3 can be formed of a light weight material rendering it easy to handle and install.

Another advantage of my invention is eliminating the handling of collected dirt in living quarters.

Theforegoing will, it is believed, sufiice to impart a clear understanding of my invention, without further explanation.

' Manifestly the invention, as described, is susceptible. of modification, without departing from collecting dirt from dirt-laden air forced into the water to escape out of the same and be filtered thereby, said casing having upper discharge openings therein for the filtered air, a suction and blower fan in the upper part of the casing, means in said casing forming therewith an annular suction channel'around said fan opening onto the same and adapted to receive dirt-laden air drawn into the same by said fan and forced downwardly-by the fan into the water, said means including a down-take duct depending into said casing and into-the water to direct the down wardly forced air into the water, said'duct having a flaring upper end forming one side of said channel and connected to said casingabove, said openings, and said ductbelowsaid upper end thereof being spacedfrom said casing to form with said casing and-said upper endof said duct an annular filtered air,up-,take chamber. leading to said openings, said channel havingtan inlet nipple adapted to be connected toa suction line leading to a room.

2. A combined dirt collecting and. air filtering device according to claim 1 whereinsaidmeans further includes a downwardly tapered deflecting member in said casing above said nipple forming the other side of said channel, and a shaft for said fan journaled in said member.
