OHIO ADJUSTABLE AUXILIARY NOZZLE FOR SUCTION CLEANERS Application filed October 8, 1924:. Serial No. 742,315.

An object of my invention is to provide an improved means for adjusting the nozzle of a suction sweeper, wherein ease and certainty of adjustment are the rime requisites.

Other objects and advantages of'the structure herein disclosed will be evident from a description of the structure shown in the drawings, wherein Fig. 1 is a side elevation of a suction sweeper showing the application of a preferred embodiment of my invention;

Fig. 2 is a partial plan View of the structure shown in Fig. 1; and

Fig. 3 is a fragmentary view of a portion.

of the structure shown in Figs. 1 and 2.

In the drawings wherein like reference characters refer to like parts throughout, a

suction cleaner is shown which is indicated generally by reference character 10. This suction cleaner 10 comprises the usual parts such as a drum 11 defining a fan chamber, motor 12, intake nozzle or hood 13, carrier wheel 14: and castor wheel 15, all parts of an ordinary cleaner.

Depending from the drum 11 of the suction cleaner are walls or flanges 62-62 extending rearwardly from the nozzle 13 on opposite sides thereof which have bottom edges substantially in the plane of the bottom of nozzle 13. Positioned upon the flanges 62-62 are lugs 66-66 adapted to function as hereinafter described.

. Positioned within the nozzle 13 with its rear wall positioned between the depending flanges 62-62 is the adjustable auxiliary nozzle comprising end plates 60-60, strip 63 connecting the forward ends of plates 60-60 and the rear member 61 which serves as a bottom plate forming, with the walls 6262, a

an air passage leading from the nozzle inlet formed by the opening between the forward edge or lip 61 of 61 and the lower edge or lip 63 of member 63. The air passaqe is bounded on the sides-by the side walls 60-60 and on the top by the nozzle 13 and drum 11 between the nozzle inlet and the eye of the fan chamber. It is to be noted that the side walls 60-60 extend rearwardly at the sides of member 61 within the walls 62-62 and are per-' pendicular to the plane of the nozzle inlet as is the connecting strip 63. Positioned upon member 61 are lugs 64-64 so positioned relative thereto that when the auxiliary nozzle is placed in operative position in the machine said lugs are adjacent the corresponding lugs 66-66 on the flanges 62-62 of the drum 11. Extending through the pairs of lugs 66-66 and 64-64 is the pivot pin 65 which supports the rear end of the auxiliary nozzle and about which said auxiliary nozzle is adapted to pivot.

Fixedly attached to the underside of bottom plate 61 forward of the pivot pin 65 is the rod 67 which extends rearwardly through an opening in the rear wall of the hood 13. The end of the rod 67 protrudes beyond the rear wall of the hood and is threaded as at 69 and mounted thereon in threaded relation is a knurled nut 70 adapted to be rotated thereon to effect adjustment of the auxiliary nozzle.

The agitating rotor 71 is carried in the nozzle. 13 by the side Walls 60-60 which are provided with suitable agitator supportreceiving slots indicated at 72. The agitator is of the usual type being provided with a belt-receiving pulley 73 near its center which is connected by means of a belt 7 4 to the driving motor of the machine as in the usual cleanerconstruction. The agitator is so positioned relative to the auxiliary nozzle that its periphery extends substantially into the plane of the nozzle inlet formed by the lips 61 and 63 and is adapted to contact the surface covering undergoing cleaning therebetween.

When in the operation of the machine it becomes desirable to raise or lower the nozzle month relative to the floor surface covering said adjustment is obtained with ease in a cleaner embodying the present invention. It is only necessary to adjust the nut 70 upon the projecting end of the rod 67 to effect the desired adjustment of the mouth as any movement of the rod 67 relative to its opening in the hood 13 results in a corresponding adjustment of the height of the inlet mouth within the main nozzle through the pivoting of the auxiliary nozzle about its pivot point.

I The construction is such that the auxiliary nozzle fits closely within the main nozzle 13 preventing air leakage therebetween and the bottom member 61 completely closes the bottom of the nozzle except for the space between its forward edge and the member 63 known as the inlet mouth.

I claim:

1. A suction sweeper having a main frame member defining a fan chamber, a forwardly extending open bottom nozzle hood, a suction passage connecting the fan chamber and nozzle hood, the suction passage defined in part by walls depending from the fan chamber, an auxiliary nozzle intake having its forward and its side edges defined by walls substantially perpendicular to the plane of the nozzle intake, and the rear edge defined by a flat unobstructed plate member having its forward portion substantially in the plane of the nozzle intake, the auxiliary nozzle pivotally mounted at substantially the rear of the nozzle hood, the unobstructed flat portion of the auxiliary nozzle comprising in cooperation with the depending walls a portion of the suction passage, a rod fixed to said auxiliary nozzle and arranged to extend rearwardly and in close relation to a portion of saiimainirame member at a point substantially above where said auxiliary nozzle is pivotally mounted, and means adjustable in connection with said rod and co-operating with said main frame member to raise and lower said auxiliary nozzle intake with respect to said nozzle hood.

2. In a suction cleaner having an open bottomed main nozzle, an auxiliary nozzle pivoted therein and forming a bottom therefor, said auxiliary nozzle comprisin a plurality of walls extending perpendicu arly to the plane of the supporting surface and a plate member cooperating with said walls to define an intake mouth for said nozzle, and adjusting means to position said auxiliary nozzle within said main nozzle comprising a rod fixedly attached to said auxiliary nozzle and extending rearwardly therefrom through said main nozzle and adapted to be moved therethrough to pivot said auxiliary nozzle about its pivot point.
