5 Claims. (Cl. 15-416) The present invention relates to suction cleaners and more particularly to a surface cleaning tool adapted to be attached to the end -of a hose connected to a source of suction.

An object of the invention is to provide a surface cleaning tool having a pair of nozzles and valve means therefor so arranged in the tool body that dirt cannot interfere with the operation of the valve means. Another object is to provide a surface cleaning tool having two nozzles and valve means therefor, the valve means being assembled through the bottom of the tool body and sealed therein from dirt by a removable cover. A further object is to provide a surface cleaning tool having a removable nozzle lip to secure valve means in the tool body. Another object is to provide a novel and improved arrangement of valve means in a surface cleaning tool. Other objects and advantages of the invention will be apparent from the following description and drawings wherein:

Figure 1 is a front elevational view partly in section of my cleaning tool;

Figure 2 is a bottom plan view with parts broken away to more clearly disclose my construction;

Figure 3 is a section along line 3-3 of Figure 2 showing the valve in different operating positions;

Figure 4 is a section along the line 4-4 of Figure 2 showing the arrangement of the valve supporting shaft; and

Figure 5 is a section along the line 5-5 of Figure 2 with parts omitted showing the valve operating member in different positions.

The embodiment of the invention herein disclosed comprises a cleaning tool body I provided with a large rear nozzle I I formed by two depending partitions I2 and I3 between which is arranged a portion of a removable cover member I having a top wall I6 which is secured to the body I0 bya pair of screws I1. The cover member I5 has side walls I8 and I9 contiguous with the partitions I2 and I3, and the wall I8 is provided with a portion defining the front nozzle lip while the real wall I9 is provided with a surface engaging face 2| for the rear nozzle I I. A gasket 22 is arranged between the nozzle front lip 20 and the partition I2, and another gasket 23 is disposed between the partition I3 and a depending rear wall 24 of the body I0 to prevent entrance Vof dirt therebetween. An opening 25 is formed in the side and top walls I8 and I6 of the cover member I5 to connect the nozzle mouth 26 with an air` passageway 21 centrally disposed in the body I0. A conduit 28 is rotatably connected to the body II) Aby a swivel joint 29 and connects the air passageway 21 with an unshown source of suction, for example, a flexible hose attached to a suction cleaner.

Forwardly of the main nozzle II is a front nozzle 39 having its mouth 3| disposed centrally ofthe body I and of less extent in widthy than the main nozzle mouth 26. The nozzle 3|] is formed by a front body wall 32 and a depending partition 33. The front nozzle 30 is connected to the air passageway 21 by a passageway 34 formed by interrupting the partition 33 at 35-35 and the partition I2 at Sii- 35, and the partitions I2 and 33 are joined by Walls 31-31 to form an opening 38 which is controlled by a valve 39. A portion of the cover member I5 covers the lower end of the partition 33 to form the front nozzle rear lip 4G and the gasket 22 prevents passage of air therebetween. A member 42 is attached by screws 43 to the body Ill and is provided with a notched edge 44 to form the front lip of the nozzle 39. A partition 45 is disposed in the nozzle 3B and its lower edge 45 is spaced above the nozzle mouth 3|. The partition 45 cooperates with the nozzle front wall 32 to provide a funnel 41 having a top inlet openingr 48 and a lower outlet 49, the latter being above the nozzle lips 40 and 44 for passage of an air stream from above the nozzle mouth 3 I, as shown by arrows in Figure 3, to the air passageway 21 and thus to the source of suction.

Communication of either of the nozzle mouths 26 and 3| with the source of suction is controlled by the valve 39 provided with notched and smooth portions 'I0 and 1| respectively for selective engagement with the surface to be cleaned. The valve 39 is rigidly attached to a shaft 50 having its opposite ends arranged in spaced valve shaft housing 5I--5l and the shaft is pivotally received in recesses 52 formed in the walls 31-31 and in spaced transverse partitions 53-53. The cover member I5 closes the housings r5I--5I and 4engages the valve shaft between the partitions 53-53 to hold the adjacent end of the shaft 59 assembled in the body I0. Arranged about the shaft 50 are gaskets 54 to prevent entrance of dirt into the valve shaft housings 5I-5i so that the dirt cannot collect about the shaft 56 and interfere with its pivotal movements. Rigidly attached to one end of the shaft 5B is a member having a recess 56 in which is disposed the bight portion 51 of a U-Shaped spring 58 having angular ends 59-59 which are tted in recesses Bil-60 formed in the nozzle body It. The member 55 has an arcuate surface 6I which rests against the cover member I5 and the latter holds through the body l and its outlet 68 is betweenf...

the nozzle mouths 26 and 3l and thus is subjected to the suction air stream passing: througheither! of the nozzle mouths to the conduit ZBto prevent accumulation of dirt in the opening (i6-f which.dif1"-t would interfere with operatioriroftheleveif 652 A brush 'i5 is disposed in a brush housing 16 and is attached to the body i {3K-by screws 11'.. Arg ranged about the body lo is a furniture guard 'l 8.

When the cleaning tool is in use theconduit-- 28 is connected to a source of suction, as for eX- ample, a suction cleaner. If it'isdesired to perform normal surface cleaning the large nozzle'- Ii is used; and its nozzle' mouth 251s connected to: the source of suction by moving the lever 65 to thev dottedV line position shown in Figure' 5, causing the valve 35 to be arranged inthe dotted line position illustrated in Figure 3 to uncoverv theopening25, and the valve is held in this po` sitionv byY the rspring 5B. In this position of the valve 39A the notched surface'lc forms part of the` nozzle front lip and the small nozzle 3lf'is dis connected from the source of suction while thel large nozzle mouth 25 is connected with' the air passageway 2l and conduit 28 and thus'tlfiesource of suction. The nozzle mouth 26 providesfor passage of a relatively large volume andA 10W' velocity'- air stream to remove non-embedded dirtfrom the surface being cleaned.

If the dirt, threads, or other litter cannot be removed by the large nozzle mouth 25 thenV the smaller nozzle mouth 3l is employed. The small nozzle mouth 3| is connected' to the source of suction by moving the lever :$53 to the fullline position in Figure 5 causing thev valve 39?. to be' moved to its full line position illustrated in Figure' 3, whereby the nozzle 3d* is connected totheair. passageway 27 and conduit 28.5 The funnel Mis also`-connected with the atmosphere above: thev nozzle body by the inlet B8 and' to the sourcezof. suction by its outlet A In this position of theV valve 39 the smooth surface 1| on the valve'contacts the surface being cleaned.

When the small nozzle mouth 3l engages the' material being cleaned an air stream. passes through the material and under thefro'nt liplMf and the portions 7| and 5G of the rear lip. The air stream passing through the small nozzle mouth 3i is of greater velocity than that which flows through the larger nozzle mouth 215 and thus functions to remove litter clinging to. the surface. An atmospheric air stream enters the funnel di' through the inlet 48 above the surface being" cleaned and' passes through the outlet 49 into the air passageway 21 to the' source of suction. This atmospheric air stream, as it passes beneath the lower end lo of the partition 45; flows at a high velocity due to thel constricted opening and enters the nap of the material exposedk in the nozzle 3l to remove the clinging litter.

In order to assemble the valve 39 inthe body l0 the opposite ends of the spring 58 are arranged in the recesses' S. and' the valve' shaft y5l-=isin sertedin the recesses 525'While the recess 56 in the member receives the spring 5B and the lever' 65 is also' inserted in the-opening Sii'. Thereafter, the cover member 5 is secured to the body I0 by the screws I1 and its inner surface contacts the arcuate face 6| of the member 55 and the shaft 50 between the partitions 53--53 to hold the valve shaft 5D in its recesses 52 to thereby assemble the parts in the body Il), The housing 5| inwhichl the' spring 58 isiarranged'isl completely sealed and? thus dirt cannot aceun'iulatev to interfere with operation of the spring 58 in holding the valve 39 in its adjusted position.

WhileI haveshown and described but a single mo'dicatiodof'my invention, it is to be understood that" 'this modification is to be taken as illustraitiveavonly andi not in a limiting sense. I dbfnot'wishstbe litnited to the particular structuresl-sldwirar'didescribed, but to include all equivalentvariations thereof except as limited by the scope ofth'e claims.
