SUCTION CLEANER AGITATOR Filed July 27, 1932 F i /V%% Patented Feb. 12, 1935 1,990,710 SUCTION CLEANER AGITATOR Frederick Riebel, Jr., Toledo, Ohio, assignor to Air-Way Electric Appliance Corporation, ledo, 01110, a corporation of Delaware '-Applicati on July 27, 1932, Serial No. 625,038

7 Claims.

' This invention relatesto-suction cleaner agitators of the type having sliding contact with a floor covering, and has as its object to improve the ability of such agitators to dislodge lint, fine hairs, etc., that may become attached to the pile of a mg or carpet. V

A further object is to attain the above end, in an agitator of a non-metallic material which not smudge the. carpet or rug which it conacts.

Another object is to provide an agitator of improved lasting and wearing quality.

With these and other objects in view my invention consists in the combination and construction and arrangement of the various parts thereof, whereby the objects contemplated are attained, as more fully set forth in the accompanying specifications, pointed out in my claims, and illustrated in the accompanying drawing, in which:

Fig. 'l' is a sectional view through a suction cleaner floor tool equipped with my improved agitators. V

Fig. 2 is an enlarged view of a portion of the working face of the agitator.

A suction cleaner employing a floor tool 10 of the type shown in Fig. .1, employs suction alone for lifting material from the floor, and the agitators 11 function to some extent to comb or part the nap fibres of the carpet, being provided with triangular shaped projections-12 for this purpose. Another function of the agitators is to provide a series of small slots 13 which direct the air in a plurality of fine streams beneath the agitaors.

The agitators 11 are in-the form of bars defining the longitudinal edges of the suction mouth of the floor tool.

The present invention aims to secure the result of dislodgment of attached foreign material by the contact of the under faces of the agitators with the naprof the carpet or rug. Present type of agitators of fibre or phenolic treated material, will wear smooth so that there is very little engaging efiect in the working faces thereof.

To this end, I provide an agitator 11 of the usual bar type, having a body 11a of hard fibre,

spears 14 are positioned transversely to the working faces of the agitators in spaced, parallel arrangement. I

The almost microscopic projections which will thus-be formed'on the faces of the agitators, will 5 engage and loosen foreign material that is attached to the nap of the carpet, yet will be of insufiicient length for lint, etc., to become attached to the agitators. Because they will re- .ceive thegreater wearing effect after having once become slightly protruded, the length of the protruding ends of the spears will remainconstaut.

The spears may be of horse hair, bamboo fibre, wire, or material of similar characteristics.

Agitators constructed according to this invention not only are more efiective in dislodging attached foreign material, but will wear longer and give more uniformly satisfactory service than former types.

I claim:

1. A suction cleaner agitator of solid nonmetallic material formed with integral agitating-teeth containing embedded spaced fibres of greater wear resisting quality than that of said material, positioned transverse to the carpet engaging faces of said teeth, both said fibres and said embedding material being adapted to simultaneously contact a fioor covering.

2. A suction cleaner agitator of solid nonmetallic material formed with integral agitating teeth containing embedded spaced fibres of greater wear resisting quality than that of said material, positioned transverse to the carpet engaging faces of said teeth and projecting a minute distance beyond said faces, both said fibres and said'embedding material being adapted to simultaneously contact a floor covering.

3. A suction cleaner agitator of solid nonmetallic material formed with integral agitating teeth containing embedded spaced metallic wires positioned transverse to the carpet engaging faces of said teeth, both said wires and said embedding material being adapted to simultaneously contact a floor covering.

4. A suction cleaner agitator of solid non- 45 metallic material formed with integral agitating. teeth containing embedded spaced bristles positioned transverse to the carpet engaging faces of said teeth, both said bristles and said embedding material being-adapted to simultaneously con 50 tact a fioor covering.

5. A suction cleaner agitator of hard fibre material formed with integral agitating teeth containing embedded spaced fibres of greater wear resisting quality than that of said hard fibre ma- 55 embedding material being adapted to simultaneously contact a fioor covering.

'1. A suction cleaner agitator of solid non metallic material containing embedded spaced fibers positioned transverse to the. carpet engaging face of said agitator; said. fibers projecting a minute distance beyond the face of said solid material and being of greater wear resisting quality than said solid material, said fibers being uniformly spaced in the solid material, whereby the fibers continue during the wearing down of both bristles and said solid material, to project a minute distance beyond the face of said solid material. g
