stage represented by the old fashioned carpet cleaner with its wheel-driven brush rotatingin Contact vgith the surface covering and performing in a primitive fashion the cleaning function desired, to a stage characterized byV positive agitation within ai suction nozzle through which air is drawn at high velocity. The inclusion in the modern cleaner of the positive agitator and high vacuum has re.
sultedin a decrease in the effectiveness of the sweeping brushtwhen' included in the combination, until finally the brush may well -be done away with and the dislodgment of the foreign vmatter in the surface covering left entirely to the positive beating element of the agitator. It is toward an agitator for suction cleaners totally devoid o`f the usual brush sweeping'means that the present invention is directed.
It is the object of the present invention to provide a suction cleaner agitator ofsim'ple` Y construction, ldurable andeiiicient. vIt is a further object of thepresent invention to provide a suction cleaner agitator in which the usual body portion has'been omitted. furi ther object is the provision of a rotor in which l the beatlng elements comprise the onlybody portion. I Other and more specific objects will appearupon vreading the specification and taking into consideration the .drawing annexe d thereto.
Referring tothe drawing: Figure 1 is a side view of an a 'tator c`onstructed in accordance with theln'esent invention; Figure 2 is a cross section-upon theline 2-2ofFigure1; Figure 3 .is a cross section of the construce tion shown inV Figure 1 upon the 'line 3'3;
Figure 4 is a disclosure of a modified em- -bodiment of the present invention;

simplicity, comprises, as
2 which are connected at diametrically opposite points by the beater bars 4, 4 which extend helically therebetween upon the surface of an imaginary cylinder of the same diameter as the end plates 1 and 2. Beater bars 4, 4 are preferably circular in cross section, of metal, an'd of sufiicient diameter so that theypossess the rigidity and strength requisite to prevent #their distortion either by bending or twisting. End plate 2 is of considerable greater width than Plate 1 andjisProvided w .with a grooved portion 5 which forms a pulle for thev drivingbelt, the portion 5 being su ciently grooved so that the belt will not extend beyond the outer surface of the end plate when position. Supporting shafts 6 and 7 are carried by end plates 1 and 2 respectively which extend perpendicularly therefrom and are adapted to be seated in a bearing of any suitable design in order that the agitator may vbe rotatably mounted in a suction cleaner.
The'mounting for the agitator inthe bearing forms no part of the present invention'.
Referring now to Figure4 in particular, a modified form of the present invention is shown in which the end plate 2 is o f the same width as `end plate 1 and a separate pulley member is provided therebetween whichis indicated by the reference character 8.
the present modification the beater bars 4, 4 are formed with a. V-shaped inwardly deflected portion intermediate their ends and in the assembled relation of the agitator the pulley8, which also has a V-shaped cross section, is seated within the V-shaped portions of the bars 4, 4 and secured in some suitable manner as by welding'. The pulley 8 is preferably positioned relative to the bars 4, 4 before said bars'are permanently attached to the Stub-shafts 6 and 7 iixedly'carried by end plates 1 and 2, as in the first modification, provide means whereby the agi-l tator may be rotatably mounted in a suitable bearing. v

bers.
tions to raise the surface covering against the lips of the nozzle containing the agitator and the beater bars 4, 4, which are rotated at high speed by the driving motor through the driving belt, contact the uplifted surface covering and impart thereto a vibratory motion through repeated impacts. The foreign matter lodged within the surface covering is dislodged by the impacts of the beater bars and the cleaning air entering the suction nozzle carries it away to the dust receptacle. rlhe operation ofthe specific agitator is the same as the agitator now in common use and no claim is made to the method of cleaning a surface covering but what is claimed as the applicants invention is an improved and simplilied agitator construction which is character# ized by its simplicity, durability and efficiency as defined by the following claims.
I claim:
1. A suction cleaner agitator comprising spaced end members, means to rotatably support said end members and means maintaining said end members in fixed relation comprising a smooth beater element.
Q. A suction cleaner agitator comprising spaced end plates, means to rotatably support said end plates and means maintaining said end plates in fixed relative relation comprising cylindrical helically-extending beater elements.
8. A suction cleaner agitator comprising spaced end plates, means to rotatably support said end plates, said end plates being connected only by cylindrical beater bars.
4. A suction cleaner agitator comprising spaced end members, means to rotatably support said end members, said end members being connected solely by rounded bars of small cross section :spacedv radially from the axis of said supporting means to Jfunction as beater bars.
5. A suction cleaner agitator comprising spaced circular end plates, means to rotatably support said end plates and rigid beater bars extending between said end plates and connected to the peripheries thereof, said end plates being unconnected save by said bars.
6. A suction cleaner agitator comprising end plates, means .to rotatably support said wiLLis r. HUDSON.
end plates, beater bars connecting said end plates, and means to recei-,ve a rotating force, said means comprising a pulley formed in one of said end plates.
7 A suction cleaner-rotary agitator com-V prising rigid beater bars spaced radially from the longitudinal axis of rotation, members connected to and extended from said bars toward said longitudinal axis, means to rotatably support said members and means carried by one of said members .to receive a rotating force, said agitator characterized by the fact that said beater bars comprise the only part of said agitator between said mem-
