5 Claims.

The present invention relates to suction cleaners in general and particularly to a new and improved suction cleaner construction in which a dusting tool, for use in off the floor cleaning, is permanently embodied in the construction. More specifically the invention comprises an improved arrangement of parts in a suction cleaner which embodies both means 'for on the floor cleaning and means for 011 the floor cleaning.

The desirability of having the dusting tool hose permanently attached to the suction cleaner unit where it is readily available for use in cleaning drapes, curtains, .and other articles which are positioned above the floor, is well recognized. Heretofore it has been unfeasible to provide a suction cleaner construction in which a suction cleaning unit for on the floor cleaning of suflicient' size and power for all around general efliciency was combined with a permanently attached dusting tool. According to the present im zntion a suction cleaner unit of the standard size and construction, in which no sacrifice has been made of cleaning effectiveness for the purpose of making possible the incorporation of the dusting tools, is provided. The dusting tools are permanently attached to the suction-creating unit and are carried in such a manner that they in no way encumber the operator in the use of the machine nor is it necessary to lift or move the machine proper in their use.

It is an object of the present invention to provide a new and novel suction cleaner construction. It is a further object to provide, in a suction cleaner, a new and novel arrangement of parts in which the dusting tools for use in oiI the floor cleaning are attached to, and carried by, the usual suction cleaner construction for on the floor cleaning. It is a further object to provide a suction cleaner construction in which the dusting tools are connected to' the suctioncreating unit and are carried by the handle of the machine. Other and more specific objects will appear upon reading thefollowing specification and claims and upon considering in connection therewith the attached drawings.

In the drawings, in which a preferred embodiment of the present invention is disclosed:

Fig. 1 is a side elevation of a suction cleaner embodying the present invention,

Fig. 2 is a front view of the cleaner disclosed in Fig. 1,

Fig. 3 is a partial s'ection upon Fig. 2,

Fig. 4 is a section upon; the line 4-.-4 of Fig. 2,

Fig. 5 is a partial section upon the line 5-5 of Fig. 2,

- Fig. 6 is a view upon the line 6-6 of-Fig. 2 showing the dust-bag-tensioning mechanism.

In the drawings,'a preferred embodiment of the present invention is disclosed and comprises a the line 3-3 of suction cleaner including a nozzle 1; a fan chamber 2 which houses a fan 2a and is provided with an inlet 3 opening from the nozzle 1, and with an outlet 4 opening to the dust bag 5; a motor casing 6 which houses a suitable driving motor for the suction-creating fan within the fan chamber 2, neither the motor or the fan being shown but being of the usual and well known types; front supporting wheels 7, 7 and a rear. supporting wheel 8, which movably support the cleaner upon the surface undergoing cleaning;' a handle 9 which is U-shaped, being pivoted upon opposite sides of the nozzle 1 at its lower end, and being provided with a grip portion 10 at its upper end. According to the present invention the pivotallyattached dusting tool can comprise a flexible tubular hose section 11, a rigid metallic section 12 which is detachably connected to the section 11 by suitable and well known securing means 13, and a nozzle 14 which is detachably secured to the Opposite end of the rigid metallic unit 12 as by common and well known securing means 15 which are preferably of the spring-pressed detent type. The dusting tool, the name generally applied to the length of hose including the flexible and rigid sections and the nozzle 14, is seat-' ed within the arms of the handle 9, which are U-shaped in cross section, and is resiliently and resistingly secured therein by means of spring members 16, 16 etc. which are carried by handle 9 at spaced intervals throughout its length.

At its inner, or suction-cleaner end, the dusting tool is detachably secured, as by means 1'7, which are similar to the means 13 and 15, to the lower end of the handle 9 which is tubular immediately adajcent the nozzle 1 and carries a sleeve 18 which is rotatably mounted upon the extended end of the transversely-extending conduit 19 within the nozzle 1. Conduit 19 connects to the inlet 3 of the fan chamber at its inner end and forms a passageway between the cleaner-end of the dusting tool and said chamber. In order to-prevent the suction-creating means of the cleaner, comprising the suctioncreating fan and fan chamber, from drawing air through the dustingtool at all times, a rotatable cylindrical valve 20 is provided in the nozzle 1 which is operable by the user and which, in one position,.seals the conduit 19 from the inlet 3 and, thru being provided with a cut-away portion 21, connects the lower end and mouth of nozzle 1 with the inlet 3. When rotated 180 degrees, however, the cut-away portion 21 contacts a wall of the nozzle 1 functioning to seal said portion, and so the interior of valve 20 from the nozzle, and instead an opening 22 in said valve faces the conduit 19 thereby functioning to interiorly connect that conduit, and so the dusting tool, with the fan chamber.

T e lower end of the handle 9 carrying the 9 as in a usual and well known manner.

According to the present invention the dust bag 5 is supported between the arms of the handle 9 there being provided, at its upper end, a frame 26 on which are mounted plungers 27, 27 which are spring-pressed to the sides of the bag by coil springs 28, 28. The outer end of each plunger 27, as is clearly shown in Figures 3 and 6, extends within a vertically extending guideway 29 into a socket member 30 which is resiliently held at the top of guideway 29 by means of a coiled spring 31. A guide pin, 32 is attached to each seat 30 and extends downwardly through the lower end of guideway 29 for the purpose of preventing undue tilting or movement of seat 30 and also any misalinement of the spring. The resilient mounting by the seat 30 of plunger 27. and so the, frame 26 and the upper end of dust bag 5, is extremely desirable as it permits longitudinal movement of the bag relative to the handle upon the pivoting of said handle, a movement which is verynecessary to prevent undue strain in the bag as the handle is pivoted. To disconnect the bag from the handle it is o necessary to force the plungers 2'7, 27 inwardly against the for of the springs 28, 28 withdrawing them from their seats 30, 30.

In the present suction cleaner the incoming power lead 33 to the motor is carried by the handle in a suitable channel 34 which extends along the underside of one of the arms thereof between the switch 35, adjacent the grip 10, and the-motor. The presence of the dust bag 5 between the depending arms of the handle in no way interferes with the disposition of an extra length or coil of the current carrying lead there being provided-the usual wrapping posts 36, 36 etc. on the underside of both arms making it possible to wrap an even longer lead thereabout than in the usual suction cleaner construction.

In the operation of the present suction cleaner in its on the floor cleaning capacity the rotary valve 20 is positioned so thatthe nozzle 1 is connected to the fan chamber and the dusting tool within the confines of the handle and offers no obstruction or hindrance to the operator in propelling the machine over the surface covering. Upon completing the cleaning of the carpets and rugs etc. if the operator desires to clean the drapes, curtains and other articles which w positioned above the main supporting surface it is only necessary to manually rotate the valve 20 until the conduit 19 is connected, through the opening 22 in the valve, with the inlet 3 of the fan chamber, which operation also effects the sealing of thenozzle 1 from said inlet. In this relationship the dusting tool is provided with suction and cleaning air is drawn through the nozzle 14. The operator needonly exert a slight pull to withdrawn the dusting tool from its seat within'the handle against the retaining force of the springs 16, 16, etc. With the dusting tool so withdrawn from its seat it is available for use at all points which can be reached by the nozzle 14, the unit being movable relative to the cleaner through the section 11 of the hose being flexible.

1 If it is desired to "xtend the nozzle 14 to a still greater distance from the cleaner it is only necessary to insert another section of dusting tool hose at any of the joints found between, the sections, as at 13 or at 15. Upon the completion of thework requiring the use of the dusting tool it is only necessary to replace theunit within its seat in the handle, rotate the permanently carried valve 20,-and the cleaner is again ready for use upon the surface covering proper.
