SUCTION NOZZLE Filed June 26, 1936 Z H:]VENTOR. 6

A ATTORNEY Patented Sept. 28, 1937 UNITED STATES SUCTION NOZZLE I Anders Eriksson-Jons,

Stockholm, Sweden, as-

signor to Eleetrolux Corporation, Dover, Del., a corporation of Delaware Application June to, 1936, Serial No. 87,385 In Switzerland July 2, 1935 2 Claims.

My invention relates to suction nozzles for use in connection with a vacuum cleaner and particularly to duplex nozzles provided with openings of different sizes which maybe selectively connected to the source of suction. When the larger opening is in use it will cover a larger surface, thereby increasing the speed of cleaning. However, if a concentrated suction is desired in order to remove dirt which the larger opening will not pick up, the smaller opening may be brought into use.

The objects and advantages of my invention will be apparent from the following description considered in connection with the accompanying drawing-which forms part 01 this specification, and of which:-

Fig. 1 is a cross-sectional view showing a preferred embodiment of my invention; and

Fig. 2 is a cross-sectional view taken on the line 2-2 of Fig. 1. t

Referring to the figures reference character l0 designates a hollow conduit adapted to be con-- nected to a source of suction and to act as a handle for moving the nozzle over the surface to be cleaned. The nozzle includes a cylindrical portion ll adapted toreceive conduit Ill and formed integral with an elongated hollow body portion l2. The lower part of portion I2 forms an elongated suction opening l3. The upper central part of portion I2 is formed as an inclined flat wall l4 formed with .an opening l5 adjacent the lower end thereof and in alignment with the interior of cylindrical portion H. The upper part l6 of wall I4 is solid.

Slidably mounted within openings formed in pressed detent I9 is provided for retaining handle member IT in either of two extreme positions.

With the parts in the position shown in Fig. 1, the interior of small nozzle member I8 is in alignment with the opening IS in wall H, and hence with the interior of the cylindrical part I I.

Consequently, all of the air drawn through the conduit ID will pass through the small suction opening 20 in nozzle member [8, thus providing a concentrated suction.

In the event that it is desired to employ the elongated suction opening l3, handle member I! is slid to the right as viewed in Fig. 1, thus moving nozzle member I8 in the same manner. this position the nozzle [8 is in alignment with the solid portion it of the fiat walland is hence removed from communication with the interior of cylindrical member H. Due to the factv that wall I4 is inclined, this movement to the right of nozzle l8 also results in its moving up a distance sufiicient so that its lower end is above the elongated opening l3. This elongated opening is now in direct communication with the interior of cylindrical portion H, whereby the suction will be applied to the entire elongated opening.

While I have shown and described one more or less specific embodiment of my invention it is to be understood that this has been done for purpose of illustration only, and that the scope of the invention is not to be limited thereby, but is to be determined by the appended, claims viewed in the light of the prior art.

'What I claim is:--

1. A suction nozzle including a hollow body portion, defining a large suction opening and a hollow integral portion adapted to be connected to a source of suction, said nozzle being formed with a port between said portions, a small tubular nozzle member slidably mounted within said body portion, and means for sliding said member to an operative position in alignment with said port, whereby all air passes through said member, and to an inoperative position out of alignment with said port.

2. A suction nozzle including a hollow body portion, defining a large suction opening and a hollow integral portion adapted to be connected to a source of suction, said nozzle being formed with a flat wall inclined with respect to the plane of'said large section opening, said wall being formed at its lower end with a port connecting said portions, a small tubular nozzle member mounted within said body portion so as to be slidable along said inclined wall, and means for sliding said member to an operative position in alignment with said port, whereby all air passes through said member, and with the lower end of said member projecting through said elongated opening and to an inoperative position out of alignment with said port and with said member retracted within said body portion.

ANDERS ERIKSSON-JONS.
