5 Claims.
My invention relates to suction nozzles and more particularly to a suction nozzle of the type having a lip agitator.
An object of the invention is to provide an improved nozzle of the above type which will more efficiently remove surface litter from a rug.
What I consider to be novel and my invention rmay be better understood by reference to the following specification and appended claims when considered in connection with the accompanying. drawing, in which Fig. 1 is a front view of the nozzle partly in section;
Fig. 2 is a bottom View of the nozzle; Fig. 3 is alsectional view taken along the line 3 3 of Fig. l;
Fig. 4 is an enlarged detail view of the securing an agitator I3 in the rear lip. Two arched gliding surfaces I4 are provided at.each end of suction slot II. Body IIJ is provided with a tubular extension I5 communicating with the interior and adapted to receive a hose connection, not shown. for communication with a source of suction such as a vacuum cleaner. Agitator `I3 is rotatably secured to body I by a fixed pivot pin I6 at one end (Fig. t)v and a threaded pivot pin I1 at the other end (Fig. Agitator I3 carries a stop pin I8 which extends into a recess I9 in body I0. Transversely extending teeth depend from the central portion of a f'lat face 2l of agitator I3 adjacent a longitudinal slot 22. Arcuate projections 23 depend from another at face 24 of agitator I3 spaced circumferentially 90 from face 2I. Projections 23 are spaced apart longitudinally along agitator I3 a suflicient distance to provide relatively large grooves 25 communicating with suction slot II.
In normal operation, the suction nozzle is reciprocated back and forth over a rug with lip I2 and agitator I3 in contact with the rug surface. As the nozzle moves forwardly in the direction indicated by the arrow in Fig. 3, the teeth 20 in face 2| comb the surface of the rug loosenl ing and moving forward any surface litter on the rug. Upon forward movement of the nozzle,
stop pin I8 engages the left end of recess I9 as shown in Fig. 3. When the forward movement stops and the rearward movement begins, agitator I3 is rotated on pivot pins I6 and I1 by the friction between the rug surface and agitator I3 to the position indicated in Fig. 6 with stop pin I3 engaging'the right end of recess I9. In this position, face 24 is -presented to the rug surface with depending projections 23' holding the rug pile spacedfrom the major portion of agitator I3. As the agitator I3 rotatesto this position, surface litter pinioned on teeth 20 is removed therefrom by the inrush ofair in enlarged spaces provided by grooves 25. Also any surface litter remaining on the rug surface that has been pushed ahead of agitator by teeth 20 is quickly carried into body II) by this inrushing air. It
-has been found that this inrush of air at the commencement of rearward stroke will remove surface litter collected by the agitator teeth 20 which may remain on the rug surface for several strokes of the nozzle if the agitator is xed in position. On a succeeding forward stroke the agitator I3 is again rotated to the position of Fig. 3 presenting teeth 20 to the rug surface.
It is to be understood that while a preferred form of the invention is illustrated, the invention l is not limited to the details of construction as shown but the scope of invention as pointed out in the appended claims.
What I claim is:
l. A suction nozzle including a body member having an elongated suction slot. a tubular extension on said body member communicating entially from said first-mentioned face, and stopk means for limiting rotation of said agitator so as to present said teeth to said surface upon movement of the nozzle in one directionand to present said projections to said surface upon movement of the nozzle in the opposite direction.
2. A suction nozzle including a body member having an elongated slot, a tubular extension on said body member communicating with theinterior of said body member and the suction slot,`
a smooth lip extending along the forward edge of the suction slot, a rod rotatably mounted at the rear edge of the suction slot in contact with a surface to be cleaned, whereby movement of the nozzle over said surface tends to cause rotation of said rod, an agitator surface formed in one face of said rod, grooves formed in another face of said rod spaced circumferentially ninety degrees from said first-mentioned face, and stop means for limiting rotation of said rod to 90's0 as to present said agitator to sait. surface upon movement of' the nozzle in one direction and to present said second-mentioned face to said surface upon movement of the nozzle in the opposite direction.
3. A suction nozzle including a body member having an elongated sucti'on slot, a smooth lip extending along one edge of the suctionslot, a rod pivotally mounted at the opposite edgelof the suction slot turnable from one position to another depending upon the direction of movement of the nozzle, a toothed agitator surface formed on one face of said rod presented to the surface being cleaned upon movement of the nozzle in one direction, and a second face having a grooved surface to permit relative free ow of air over the surface being cleaned and presented to the surface being cleaned upon movement of the nozzle in the opposite direction.
4. A suction nozzle including a body member having an elongated vsuction slot, a smooth lip l extending along the forward edge of the suction slot, a. rod pivotally mounted in the rear edge of the suction slot reciprocable Vfrom a rst position upon forward movement' of the nozzle to a second position upon rearward movement of the nozzle, one face of said rod having depending teeth presented to the surface being cleaned upon forward movement of the nozzle, and a second face having spaced depending projections between elongated grooves presented to the surface being cleaned upon rearward movement 'of the nozzle.
5. A suction nozzle including a body member having an elongated suction slot, a smooth lip extending along the forward edge of the slot, a rod pivotally mounted at the -rear edge of the slot reciprocable oy frlctional engagement with a surface being cleaned from one position upon movement of the nozzle in one direction to a second position upon movement of the nozzle in the reverse direction, one face of said rod .being formed with depending teeth presented to the surface being cleaned upon movement of the nozzle in one direction, and a second face of said rod having depending projections between elongated grooves presented to the surface being cleaned by the movement of the nozzle in the reverse direction.
