Patented Mayy 1 7, 1938 UNI-TED STATES SUCTION NOZZLE Anders Eriksson-Jens, Stockholm, Sweden, as-

signor to Electrolux Corporation, Dover, Del., a corporation oi' Delaware D Application June 26, 1936, Serial No. 87,383 In Switzerland July 2, 1935 s claims. '(01. 1'5-155l The objects and advantages of my invention p will be apparent from the following description considered in connection with the accompany- 15 ing drawing which forms part of this specication, and of whichz- Fig. 1 is a cross-sectional view of a preferred embodiment of my invention;

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

Fig. 3 is a cross-sectional view similar to Fig. 1 but showing the parts in a different position. Referring to the figures, reference character lil designates a. conduit by which the nozzle.' designated generally by reference character II, is connected to a source of suction. Conduit I is preferably rigid whereby it may serve as a handle for moving the nozzle over the surface to be cleaned.

Nozzle Il includes a preferably cylindrical portion l2 adapted to receive conduit I0 and an elongated hollow body portion I3 formed with an elongated suction opening I4. An inner Wall l5, preferably integral with cylindrical portion 35 Il, includes a semi-cylindrical part I6 and a iiat part I'I. Send-cylindrical part I6 forms wittlilylindrical portion a semi-cylindrical slo Rotatably mounted on parts I1 by means of 4U a screw I9 is a small nozzle member 20 having a cylindrical portion 2| and a mouth piece portion 22, the latter forming a small suctionl opening 23. Cylindrical portion 2| is formed withi an opening 24 adapted to be aligned to the in- 45 terior of the elongated portion I3 when the parts are in the positionshown in Fig. 3. A

spring pressed detent 25 is mounted in inner wall I6 and is adapted to engage recesses formed in small nozzle member 20 in order to retain it 50 in either the position shown in Fig. 1 or -that shown in Fig. 3. f

The operation of the above described nozzle is as followsz- With the parts in the position shown in Fig. 1,

55 communication is 'established between the small Y suction opening 23 in small nomle member 20 and the interior of cylindrical portion I I to which is connected the conduit |II. Consequently, a concentrated iiow of air will take place through opening 23,v thus enabling the nozzle -to pick up either heavy articles or articles which tend to adhere strongly to the surface undergoing cleaning. .Mouth piece portion 22 is of suillcient length so that, when in this position, it extends below elongated opening I4 and hence contacts the 10 'surface to be cleaned. It will be noted that communication between the elongated opening |4 and cylindrical portion I2 is closed by cylindrical part 2| of the smaller nozzle member 20.

For ordinary cleaning the small nozzle member is rotated in either direction through 180 degrees to thegposition shown in Fig. 3, thus permitting the elongated opening I4 to come into operative relation with the surface to be cleaned. In this position the small nozzle opening 23 is closed by the inner wall I5, while the elongated opening I4 is connected through the opening 24 in the cylindrical portion 2|, whereby air is drawn in through the elongated openmg.

While I have shown and described one more or 25 less specic embodiment of my invention it is to vbe understood that this has been done for purposes of illustration only, and that the scope of the invention is not to be limited thereby, but is to be determined by the appended Vclaims viewed in the light of the prior art.

What I. claim is:-

1. A suction nozzle including a hollowbody portion formed with a large suction opening and an outlet opening adapted to be connected to a source of suction, and a small nozzle member rotatably mounted in said body portion and formed with a restricted suction opening, said body portion and said small nozzle member being formed with complementary valve structure whereby. rotation of saidA small nozzle` member establishes communication selectively between said large suction opening and said outlet opening and between said restricted suction opening and said outlet opening.

"2. A suction nozzle including a hollow body portion rigid with' respect to a hollow member adapted to be connected to a suction conduit, said body portion being formed with a large suction opening, a small nozzle member rotatably mounted in said body portion and formed with a small suction opening, a. cylindrical part ,i formed integral with said small nozzle opening, and an inner semi-cylindrical wall integral with tion in which it extends below said body position to contact the oor and to space said body portion from the floor and an inoperative position in which it is removed from the floor, and means for connecting said restricted opening with said outlet opening and closing said large opening when said small nozzle member is in said operative position and for connecting said large opening to said outlet opening and closing said restricted opening when said small nozzle member 10 is in said inoperative position.
