VACUUM CLEANER}.

Specification of Letters Patent. Patented 31:11. 21, 1922.

Application filed July 30, 1920. Serial No. 399,990.

To all whom it may concern:

Be it known that I, Aininaw W. ANDER- son, a citizen of the United States, residing at Enid, in the county of Garfield and State of Oklahoma, have invented certain new and useful Improvements inVacuum Cleaners, of which the following is a specification.

This invention relates to vacuum cleaners and has for an object to provide a device of this character which is susceptible of being taken apart whenever desired, thus permitting the device to be cleaned or disassembled and put to other uses.

A further object is to provide a vacuum cleaner having a suction creating element which can be separated from the body structure of the cleaner and used with or without other attachments for the cleaning of various and different objects.

As a further object the invention may be said to provide in general a vacuum cleaner of new and novel construction particularly adapted for the cleaningand sweeping of carpets, being provided with brush means connected to and driven by a fan of the suction element.

With the above and other objects in view the invention may be said to residein the details of construction, combination and arrangement of parts as will be hereinafter more fully pointed out, reference being had to the accompanying drawings wherein Figure 1 is a side elevation of a cleaner constructed in accordance with the invention.

thereof.

Figure 3 is a horizontal section taken on line 3-3 of Figure 2.

Figure 4. is a top plan view of the wheeled bottom of the cleaner.

Figure 5 is a top view of the motor and fan casing.

Figure 6 is a plan view of the bottom plate of the casing, and

Figure 7 is a view in detail of the revoluble brush.

Figure 8 is an end view of the brush.

In carrying out the purposes of the invention, the cleaner is provided first ilith a. lower body carrier I mounted on the asters Figure 2 is a vertical cross sectional view 2 so as to be easily propelled over a floor or carpet when pushed forward by means of the handle 3, the latter being attached to the carrier in any suitable manner as shown. The carrier 1 is provided upon its upper surface with an annular flan e 4 and extending upwardly and centre ly within this flange is the flared mouth or circular end 5 of a suction nozzle 6, the latter being flared at its outer end in the usual manner and bent downwardly for enga ement over the surface to be cleaned. The ower end of the nozzle is, of course, open and revolubly mounted above this opening, is a brush 7 which is designed to turn during the propulsion of the cleaner so as to loosen the grit or dirt on order that it may be more easily drawn into the nozzle b the suction created therein.

Sup )orte upon the wheeled-carrier 1. so asito removable therefrom is a suction creating element, indicated generally at 8, and comprising a motor and fan casing preferably of a single casting and including an upper cylindrical portion irovide a receptacle or motor container bemg slotted vertically as indicated at 10 and enlarged as shown at 11 in order to suitably accommodate and support the motor therein. The motor being removable whenever desired.

At the lower end of the cylindrical container there is formed a circular fan casing 12 which is designed to he closed in by a hell-shaped plate 13 This plate has an annular flange 14 which embraces the fan casing 12, hcing provided with a cut out 18' for the passage of pipe 18; bolts or other fastening means 15 being em iloyed to fasten the plate 15:- securely to tile casing. At its center the plate is provided with a circular opening 16 of substantial size and the center of the plate is )ressed inyas at 17,.to form a flared mouth portion which fits snugly over the opening 5 of the suction tube 6 when the element 8 is connected to the wheeled body or carrier of the cleaner. An outlet pipe 18 is located on one side of the fan casing and has a flange 19 for connecting to the flange Q0 of the dust collector or bag Zl. whatever dirt or grit, etc. is

the surface of the carpet, etc., in p 9 designed to one and to the shaft of the fan, and

drawn in through nozzle 6 by the suction or the rotating fan thuspasses through the fan casin and of the outlet 18 so as to finally'lodge in the dust collecting ba 21.

The an consists of a round, flat dis 22 carrying a plurality of straight, radially disposed blades 23. These blades are positioned adjacent the peripheral edge of the disk in-laterally spaced relation to rovlde an open space at the center of the disk and above thenozzle openin 5. The fan'dlsk is also provided with a short shaft 24 which projects up through thebottom wall 25 of the motor casing, being provlded abovethe wall with an etdarged disk shaped head 26." Bearings are suitably arranged about the shaft so as to iiable the fan to be turned easily within the casing, the fan being of course, actuated b the motor contained witilr in the casing. p the. fan thet'dis' are s 26 is provided wit projections 27 to be received in the recesses of the clutch head 28 of the motor drive shaft; the engagement efone with the other providin v a suitable drive connection between thq motor and the fan for the actuation of he latter within the fan casing. When the element 8 is attached to the'carrier 1 it will be seen that the flange 29-01- the bell shaped plate 13 embraces the flung: 4 of the carrier upon the outside and secured thereto by means of screws or bolts 30. The matter drawn into the tube will be discharged into the open space at the center of the fan blades and subsequently caught amlwhirled about by the revolv-, ing fan blades by which it is propelled out through the outlet pipe 18 and into the dust collecting bag 21. Projecting upwardly through the discharge end of nozzle 6, through a bearing 32, is a vertically disposedrrod or shaft suitably connected at rojectirlkg downwardly through and below the tube "6 and having a pulley 34 at its lower end. This pulley is connected to a pulley 35 of the brush 7 by means of a belt or chain 36. The brush has its axle ends 38 journaled in suitable bearings 39 provided at ear-h end of the nozzle 6 as swam in. Fignlre 4 of the drawings, and is thus rotated whenever, the fan is turned on. It may thus be seen that, as the machine is being propelled forward over a carpet or other surface to be cleaned, the dust, grit or other material collected from the surface thereof by the rotating brush 7 is drawn up through the suction tube 6 by means of the suction of the rotating fan in the manner previously described. The cleaner therefore not only acts as a suction cleaner for removing all surface dirt from carpets. etc. but is also adapted by reason of the driven brush 7 to more effecti'vely clean the carpet, etc, b

brushing the surface of'the same sufiicient y to loosen any rit or diri fiwhich may have become so 1m ordinarily or easily loosenedby mere surfacecleaning.

' An. important feature of the invention is the fact vthattheelement 8 is detachably as soeiated with the supporting bod 1 and may consequently be readily taken 03 upon loosening'the-fastening means 30 and used as an independent cleaning element, since the motor contained. within the cylindrical container portion provides the neessaryfdrivmg power andth'en'ewolvingfan and bag 21,; the necessary .s't'ictiion and receptacle means for hous'i th'e diit drawn through theifan casingrg vhen used as a separate cleaner, the brush drive connection 33,012.,

'rxthe purpose of drivin Ewould of courseyb'e disassopihted from the fan. The bellfs'b'a ed plate 13 provides attachments such as are signed 'forand used in; connection with other vacuum cleaners,; may be used equally well with this invention and with good results whether they be in the nature of scraping strips and curry of horses and cattle, or as special-nozzles adapted for cleanin of couches, walls, curtains, clothes,'-etc. i or the convenient handling of the elentent B when used separately and apart from the vacuum cleaner as a whole,, it will be dis means (not s own), Y

It is also apparent that the extent to which the element 8 may be used is large and that itis-susceptible of being applied n nu-. merous other ways then specified; In reducing it to practice, it may be feasible to adopt various modifications and corrections andalt'erations in the design, shape and size of the cleaner and it all of which changes; corrections, 'etc., arfil permissible as properly fall within the scope of the invention as defined in the appended claims. I

Having thus described the invention what I claim as new and desire to sccureby Let ters atent is 1. In a suction cleaner, the combination of a lower body carrier havin an upstanding flange centrally from WlIlCli xtends a surtion nozzle hr-nt d wnward and dared at its suction end. an integral motor and fan cusing, a hell -lmpcd plate havin its central portion bun inward to form a arcd mouth which fit ovcr said nozzle and is dctaclmbly held to said carrier. said fan casing dr-tac-hably hold to said plate. :1 fan held in said casing. and a m tor for who? a said fan, said fan casing ha ing an outlet 2.
