ermany June 16, 1932 4 Claims. (Cl. 15-158) My invention relates to the vacuum cleaner art and particularly to a suction nozzle intended to be used in conjunction with a vacuum cleaner unit. 4
More particularly, my invention contemplates a suction nozzle comprising two parts which may be readily secured together or separated; One of the parts comprises brush bristles adapted to surround the other part. The other part comprises a hollow resilient suction mouth piece. When the two parts are together they constitute a suction brush. When the part including the bristles is removed the resilient mouth piece may advantageously be separately used for cleaning.
The nature of my invention will be apparent from the following description considered'in connection with the accompanying drawing, which forms a part of this specification and of which:
Fig. 1 is an elevational view showing my suction nozzle connected by means of a flexible hose with a vacuum cleaner unit; and
Fig. 2 is a view partially in cross-section, of the suction nozzle shown in Fig. 1.
Referring to the drawing, reference character l designates a vacuum cleaner unit which comprises a casing I I mounted on suitable wheels I2 and enclosing suitable dust separating means and suction producing means. A flexible hose i3 is connected to the inlet I4 of the cleaner unit and v to a rigid hollow handle member I5. The other end of handle I5 is secured to my improved suction nozzle, designated generally by reference .character I6.
Nozzle I6 comprises a plate or base member I'I made of any suitable rigid material such as wood or metal. Plate member i1 is formed with a central aperture I8. Brush bristles 9 are secured in and extend downwardly from the lower face of member I! adjacent to the periphery of the base member and around opening I8.
Reference character I9 designates a hollow member made of relatively soft resilient material, such as rubber. One end of member I9 is formed with a reenforced portion 8 which is adapted to receive and resiliently engage one end of hollow handle I5. The other end of member I9 is formed as part of a sphere 29, the lower portion being cut off, so to speak, to form a suction opening 2|. The diameter of sphere 20 is greater than the diameter of aperture. I 8 in member I1. Member I9 is formed with a bead 22 spaced a short distance above the sphericalportion 29 and the member is preferably formed so that the upper part, including reenforced portion 9 is at an angle to the vertical when member I1 is horizontal.
In order to separate members I1 and I9, the spherical part 20 of the latter may be compressed, due to the resilient nature thereof, and withl drawn upwardly through the aperture I8. Likewise, when the two parts are to be placed together, spherical part 29 may becompressed and inserted into aperture Iii. Member I1 is securely held on member I9 between the spherical portion 1 thereof and the bead 22.
In operation, when the two parts are placed together and connected, by means of the handle I5 and the hose I3, with the vacuum cleaner unit I0, and the latter is operated, air will be drawn in through the opening 2| and through the member I9, handle I5 and hose I3 tothe dust separating member within the cleaner'unit. If the cleaning member is passed over a surface to be cleaned with the bristles 9 in contact with the surface, the bristles will dislodge dirt adhering to the surface, which dirt will be picked up by the air drawn into opening 2i and carried with the air stream to the dust separating member ID. The part 29 is resilient and can be squeezed to adjust the size of the suction opening. It will be clear from what has been stated above that the base member H with the bristles 9 maybe pulled oif the member I9 and there is then provided a simple resilient nozzle.
The invention facilitates manufacture of this type of nozzle.
While I have shown and described a preferred embodiment of my invention, it is to be understood that this is for purposes of explanation only, and that the invention is to be limited only by the appended claims viewed in the light of the prior art.
What I claim is:
1. A suction nozzle comprising a base member 40 of rigid material formed with a central aperture, brush bristles secured to said base member and extending at right angles therefrom around said aperture, a hollow resilient member adapted to extend through said. aperture and resiliently engage said base member, and an annular projection on said resilient member for positioning it with respect to said base member, said resilient member being formed with means for connectin it to a source of suction.
2. A suction nozzle comprising a base member of rigid material formed with a central aperture, brush bristles secured to said base member and extending at right angles therefrom around said aperture, a hollow resilient member adapt- 55 ed to extend through said aperture and resiliently engage said base member, the portion of said resilient member extending through said base member adjacent to said bristles having a larger diameter than the rest of said resilient member and having a suction opening 'in the lower part thereof, and an annular projection on said resilient member spaced from the spherical portion, said base member being adapted to be held between said projection and said portion of larger diameter, said resilient member being formed with means for connecting it to a source of suction.
3. A suction nozzle comprising a base member of rigid material formed with a central aperture, brush bristles secured to said base member and extending at right angles therefrom around said aperture, a hollow resilient member adapted to extend through said aperture and resiliently engage said base member, the portion of said resilient member extending through said base member adjacent to said bristles being formed as a part of a sphere and. having a suction opening in the lower part thereof, and an annular projection on said resilient member spaced from the spherical portion, said base member being adapted to be held between said annular projection and said spherical portion, said resilient member being formed with means for connecting it to a source of suction.
4. A suction nozzle comprising a tube of resilient material, the lower end of which has walls of substantially uniform thickness forming an enlargement, a brush member having a substantially rigid flat back fitted. around said tube of resilient material and abutting said enlargement to limit longitudinal movement of the back in one direction, said nozzle and back being further configured to prevent accidental longitudinal displacement of the back relative to the nozzle in the other direction. r
