1936, Serial No. 112,624

In Germany November 26, 1935 1 Claim.

relates to vacuum cleaners and more particularly to improved suction nozzles for use with vacuum cleaners.

One of the objects of my-invention, -1s 5 vide a nozzle including gularly movable with to. protwo parts which are anrespect to each other in order that the part including the suction mouthpiece may independen extend in practically any direction tly of the direction ofthe other part,

which is conveniently connected to the suction conduit.

A further object vision of a of my invention is the pronozzle of this type which is of sturdy,

simple and cheap construction and easily assembled.

Further objects and advantages of my invention will'be apparent from the following description considered in connection with the accompanying drawings forming part of the specification and of which:

Fig. 1 is a view of a preferred embodiment of my invention in use in conjunction with a vacuum cleaner;

Fig. 2 is suction nozzle shown in Fig.

Fig. 3 is with the parts chiefly in cross-section of a a view of a nozzle found in Fig. 2 in a different relative position;

a view,

Figs. 4, 5 and 6 are detailed views of portions of the nozzle shown in Fig. 7 is other embodiment of Fig. 8 is with the pa Fig. 9 is bodiment of my Referring fmore particularly to Fig. 1, reference chara cter 9 designates a vacuum cleaner unit to which is connected a hollow, rigid suction conduit I l by means of a flexible hose l0. Se-

cured to the end of conduit H is the nozzle [2 which forms the subject invention. Figs. 2

low members l3 at one end with a adapted to of conduit matter of the present Referring now more particularly to through 6, the nozzle l2 includes two holandv l4. Member 13 is formed tapered bore l5 which is receive and engage the tapered end H. The other end of member I3 is formed as a hemispherical portion iii, the circular edge of which lies in a plane oblique with of bore 15. Member I4 is similar hemispherical portion H,

the circular edge of which is likewise disposed in a plane oblique with respect to the axis. The edge of hemispherical portion I6 is formed with a shoulder l8 which fits within the circular open- (Cl. ass-96,8

ing in hemispherical portion I1, thus preventing radial displacement of the two members. The edges of hemispherical portions l6 and I! are retained in contact with each other bymeans of an arcuate resilient band l9 overlying the exteriors of the hemispherical portions and provided with projections 20 at either end which engage recesses 2| formed in the exterior of the hemispherical portions, as shown in Fig. 5. The recesses 2| are formed at opposite ends of a diameter which extends normal to the plane of the mating-edges of the, hemispherical portions. The band I9 is also normal to this plane. Consequently, the hemispherical portions are relatively rotatable with respect to each other about an axis which coincides with the above mentioned diaimeter.

The resiliency of band l9 holds the two hemispherical portions together in substantially airtight relationship and also permits easy assem bly. To assemble the parts, the band i9 is sprung sufficiently for the projections 20 to pass over the outer surface of the hemispherical portions, and its resiliency causes it to contract and engage the projections 20 within the recesses 2|.

The end of member H opposite from hemispherical portion l6 constitutes anozzle opening 22. Brush bristles 23 surround this opening and are held within a metal retaining ring is disposed partly. within an formed in member M. A rubber ring 26 is preferably placed around a shoulder 21 formed on member l4 and extends downwardly to conceal retaining member 24 and also serves to hold the retaining member in the recess 25. A hollow cylindrical member 28 is preferably disposed within the brush bristles 23 and serves to prevent the bristles from being drawn into the suction opening 22 by the inflowing air.

i3 and i4 may be retained in any desired position, one, of the hemispherical portions is provided with one or more detents 29 adapted to be re-" ceived in one of a series of recesses 30 formed in the edge of the'other hemispherical portion, as is'shown' more particularly in Fig. 4. The re;- siliency of band l9 permits the slight separation of the two edges necessary for the detent to pass from one recess to the next. v When the detent is received in a recess, band I! maintains a substantially air-tight joint between the 24 which annular groove 25 U the edge of ators hand. The parts l3 and it of the nozzle may be placed in any desired angular relation to each other. Fig. 1 shows the use of the nozzle for cleaning a ledge or moulding disposedabove the operators head. As here illustrated, the two parts of the nozzle are rotated to a position in which the angle between them is less than 90 degrees, thus making it possible for the part Id to be in a substantially vertical position 8.!- though the part l3 and the conduit ll connected thereto extend downwardly from the nozzle.

In the embodiment shown in Figs. 7 and 8, the parts l3 and IE are formed cylindrically with the edges of their mating-ends disposed in a plane oblique to their axis. An outwardly extending flange 35 is provided around the oblique edge of member 03, while a similar flange 36 is provided around the edge of member H3. These flanges are retained in contact with each other by means of a channel-shaped resilient ring 31 which is split, as is shown at 38 for the purpose of assembly. Means, such as the detent 29 and recess 30 shown in Fig. 4 may be employed to retain the members in any desired angular position.

In the embodiment shown in Fig. 9, the parts l3 and It are formed with hemispherical ends it and E7 in the same manner as described in connection with the embodiment illustrated in Figs. 1 through 6. Each hemispherical portion is provided with a groove adjacent to the circular edge and a resilient channel-shaped ring ii, similar to ring 37 shown in Figs. 7 and 8, has its flanges engaging within these grooves. Ring 4i serves to retain the members in rotatable re lation in the same manner as described in connection with the previous embodiment. The inner surfaces of the hemispherical members are aaoaqse provided with ribs 42 which are disposed in plane parallel to the air passages formed in their respective members. The purpose of these ribs is to reduce swirling of the air as it passes through the hemispherical space formed by the two hemispherical portions. This swirling, under certain conditions, results in an undesirable noise. The presence of ribs 42 tend to cause the air to pass through the spherical space without swirling.

While I have shown and described three more or less specific embodiments of my invention, it is to be understood that this has been done for purposes of illustration only and that the scope of my invention is not to be limited thereby, but

is to be determined by the appended claim viewed in the light of the prior art.

What I claim is: In a suction nozzle including a first member having an air passage adapted to be connected to a source of suction, a second member having an air passage communicating with a nozzle opening, each of said members formed with a hemispherical end having a circular edge in a plane oblique with respect to the respective air passage, means to secure together said sections in coupled relation comprising an arcuate resilient band overlying said hemispherical ends and removably engaging the hemispheres at the opposite ends of the diameter normal to the plane of said edges, and means to retain said band in engagement with said hemispheres to resiliently hold said hemispherical ends together in sub-' stantial air-tight relation while permitting them to be pivoted relative to each other through a relatively wide angle, the resiliency of said band retaining the edges in abutting contact.
