SUCTION NOZZLE Filed July 27. 1938 ATTORNEY.

assignmto Electrolux Corporation, Dover, Del., a corporation of Delaware Application July 27, 1938,. Serial'No. 221,509 In Germany August 2, 1937 3 Claims. -(Cl. 285-21) My invention relates to vacuum cleaners and more particularly to an improved suction nozzle for use in connection with a vacuum cleaning unit of the type wherein means are provided for detachably connecting the suction nozzle to a hollow rigid handle and a flexible hose.

With a nozzle of this type it is desirable to have the hollow handle extend therefrom at an angle of approximately 45 when the nozzle is being used for cleaning a floor. ,However, when it is desired to clean underneath 10w furniture, or to clean a surface which is above the level on which the operator is standing, it is preferable to have the handle extend substantially parallel to the floor or other surface being cleaned. Heretofore, this has been accomplished by connecting the handle to the nozzle by means of some type of pivoted or swivel connection. However, this entails a rather expensive construction and also tion will be apparent from the following description, considered in connectionwith the accompanying drawing, which forms a part of this specification, and of whichi Fig. 1 is 'a cross-sectional view of anozzle in accordance with my invention; and

,Fig. 2 is a rear view of the nozzle shown in Fi ure 1. A Referring to'the drawing, reference character Ill designates a hollow body formed with a lower elongated inlet opening II, which may be surrounded by brush bristles l2. A strip of rubber l3 .may be provided around the body l and serve both as abumper and as a means for supporting the bristles H. The space-within the body ID, to which the elongated inlet ll opens, converges to a centrally located circular opening It in the upper face of the body In.

Secured to the body by means of screws I5 is a hollow connection member l6, Member I6 is formed with two intersecting bores, one of which is'bounded by a slightly conical surface l1, while the other is bounded by a similar conical surface l8. These two surfaces intersect along a line I! which forms a portion of an ellipse. A hollow rigid handle member 20 has one end formedslightly conical and is adapted to be received within either of the bores. As shown in solid lines in Fig. l, the handle is received in the bore which is bounded by the surface ll andin this position extends at about 45 to the surface 6 with which the nozzle is in contact. It will be seen that in this position the handle 20 completely blocks off the bore which is bounded by the surface I8. If it is desired to use the nozzle under low furniture or for any other use in 10 which the handle should extend substantially parallel to the surface being cleaned, the handle is removed from the position shown in full lines and placed in the position shown if. broken lines, where it engages the bore which is bounded by the surface l8. In this latter'position it completely blocks off the other bore.

in order toprovide a somewhat better bearing for the handle in the nozzle when it is inserted in the full line position, which is the position in which it is chiefly used, a supporting member 2| may be provided-which engages the lower upper side of the handle. The surface 22 on the member 2| which contacts the handle is made slightly conical. As will be seen from the drawing the 26 member 2! is further provided with a surface contacting the under side of the handle when it is inserted in the nozzle in the broken line position, thus forming an improved bearing for the handle in said position. The member 2! should be com- 80 paratively narrbw so as not to interfere materially with the flow of air when the handle is in the broken line position.

It will thus be seen that I have provided a nozzle and handle which may have different relative 86 angular positions without requiring the use of any pivoted joint. While I have shown one preferred embodiment in my invention this has -been done for purposes of illustration only, and

has not intended to limit its scope, which is to 40 be determined by the appended claims viewed in the line of the prior art.

vI claim:

'1. In a suction nozzle, a hollow body formed with an inlet and a plurality of outlets, said outlets being in the formof mutually intersecting bores, and a conduit member having an open end and a solid side wall receivable in any of said bores, the relationship of the intersecting bores being such that when said conduit member is received in any bore the solid side wall thereof extends across the remainder of said bores to thereby close. the latter.

2. In a suction nozzle, a hollow body formed with an inletand twointersecting outlet passages, a conduit member receivable in either of said passages, the relationship of the passages being such that-when said conduit member is received in either passage it blocks 01f flow through the other passage, and a projection within; said hollow' member provided with a surface which is aligned with the interior surface of one of said passages sowasto contact and support said conduit member when the latter is received in said one of said passages.

3. In a suction nozzle, a hollow body formedwith an inlet and two intersecting outlet passages,

, either of said passages.
