VACUUM-CLEANER N OZZLE Application led Marchr 30, 1928. Serial No. 265,869. l
This invention relates tok a vacuum cleaner nozzle.
An object of the invention is to provide a vacuum cleaner nozzle which will roll up threads and similar articles so that they will becaught by the current of air and carried 0H from the oor or other surface.
Another object is to provide means in a vacuum cleaner nozzle which will centralize the air currents and, therefore, more efliciently carry off the dirt.
Another object is to provide a vacuum cleaner nozzle which may be moved in different" angular positions with respect to the operating handle, so as to fa ilitate working around and under furnitur Other objects and advantages will become apparent as the description proceeds.
embodiment of the invention is illustrated in the accompanying drawing, wherein,
Figure 1 is a perspective view of the nozzle disclosing the underside of the same.
Figure 2 is a bottom plan view. i
Figure 3 is a sectional view taken onlin 3-3 of Figure 2, the nozzle being shown as passing over a rug or carpet, and
Figure 4- is an end elevation of the nozzle. The nozzle comprises an elongated hollow portion 10 forming a main suction chamber provided with an elongated slot on the side which engages the surface to be cleaned, and gradually increasing in depth toward the center thereof, at which point it merges into a connecting pipe 11. y This pipe extends from the portion 10 at approximately a 45 angle, and may be either integral with such portion or a separate member attached thereto. An elbow 12 having a reduced end 13, adapted to have a swivel fit within the pipe 11, is used for connecting the nozzle to the operating handle and the other parts .of the vacuum cleaner. The angularity of the elbow is such that when the same ismoved into certain positions the operating handle will be ina pol sition so that the nozzle may be run around or beneath furniture or other low objects in the room. One of the last vmentioned positions of theelbow is clearly shown in Figure 3, and it should be apparent that when the v threads same isrevolved 180 that the free end there of will be projecting substantially vertically. The main suction chamber or elongated hollow portion 10 of the nozzle is provided' with a relatively wide lip 14 across its lower 55 front edge and a relatively narrow lip '15 across its lower rear edge, said lips being `connected at theoppositeends ofthe suction chamber by curved lip portions 15a. The lip 14 is provided 4with a4 series of longitudi- 60 nally extending ribs 16 of less length thany the` lip forming between the same grooves 17, the height of the ribs 16 being substantially the same as the height of a bead or rib 18 adjacentto the junction point between the lip and the portion 10 of the nozzle; However, the forward part of the lip 14 is inclined at a slight angle upwardly as shown in Figures 3 vand 4, so that there will be a small clearance between the front end of such lip and the surface upon which the nozzle is resting. This angle is shown in Figure 4 by the lines A, B, its apex being indicated at 18a. The-pur ose of this arrangement will be later descri ed.
Adjacent each end of the lip 14 but in- 75 wardly therefrom are annular or other de pressions 19, 4having apertures 2O extending through the lip and communicating with the exterior of the nozzle. Since the ribs 16 and grooves 17 communicate with the depressions S0 19, it is quite clear, because of the apertures 20 and a centrally arranged transversely and vertically extending groove 2l communicating with the main suction pipe 11, that a limited amount of air will be free to pass through the apertures 20, the
The lip 15 adjacent the rear edge of the nozzle has its forward ed e rounded, as shown jat 22, while its rear e ge is provided preferably at the middle portionthereof with a relatively elongated longitudinally. extending notch 23. This notch is transversely aligned with the notch 21 in the kfront lip, and is also arranged beneath the pipe 11, as clearly shown in Figure 2.
' en the nozzle is pushed across the surface being cleaned,as shown in Figure 3,
and other articles will `pass under -the lip because'of the inclination'ofits front chamber fat the edge and the ribs 16, when the nozzle is forwardly tipped about the point 18a, will act as a comb to roll them into thread-like form so as to be more readily carried away'by the air currents. The groove 21 connecting the grooves 17 with the hollow portion 10 permits of a limited suction action which helps to twis and roll such loose matter into stringlike orm as the nozzle is shoved over the surface being cleaned.
When the nozzle is at the position shown in Figure 3, the lips 14, 15 and 15a surrounding the slot of the main'suction chamber or hollow* Yportion I10 form a seal entirely around the same, except for the small air current passing\ through the apertures 20,
order to break this seal and tocentralize the suction action of the device it is merely necessary to tip the nozzle backwardly about the rear edge of the lip 15, raising the lip 14 from the surface whereupon the groove or notch 23 serves as a free opening or valve for the ingress of air into the suction chamber or hollow portion 10.
As this notch is arranged at the middle portion of the device and adjacent to the pipe 11, it will be quite apparent that the a1r current thus brought about w1ll be concentrated and of greater eiiciency than were it spread out over the entire extent of the nozzle. Although a preferred embodiment of the nozzle has been shown and described, it should be understood that the invention is susceptiblev of various modifications and adaptations within the scope of the following claims; and 'that the ribs and grooves might be on the rear lip, the notch 23 differently located, or other changes made without departing therefrom. .Y l
Having thus described my lnventlon, I claim is:
1. A vacuum cleaner nozzle having a main what . suction chamber and a suction slot, a lip arranged on an edge of such slot having ribs and grooves extending longitudinally thereof whereby as the nozzle is passed across a surface loose articles w1ll be curled or rolled up. 2. A vacuum cleaner nozzle having a mam i suction chamber therein and an elongated slot in the side of the nozzle in communication with the chamber and which engages the surface to be cleaned, said slot being surrounded by lips adapted to make sealing engagement with the said surface, and one of said lips being provided with a series of ribs and grooves extending substantially parallel with said slot.
3. A vacuum cleaner nozzle havin a main suction chamber therein and an e ongated slot formed therein extending transversely of the direction of movement of the nozzle on the surface to be cleaned, said slot being surrounded by lips which engage the surface to be cleaned and one of said lips being relatively wide and having a series of ribs and grooves extending substantially parallel with said slot. j
4. A vacuum cleaner nozzle having a main suction chamber therein and an elongated suction slot formed in the side of the nozzle communicating with the chamber and which engages the surface to be cleaned, said slot being surrounded by lips making sealing engagement with said surface, one of said lips which extends longitudinally of said slot being relatively wide and having its working face in an inclined plane making a small angle with the working face of the other of said lips, and said first-mentioned working face having ribs and grooves therein extending longitudinally of said slot.
5. A vacuum cleaner nozzle having a-main suction chamber and a slot formed therein, a lip arranged adjacent an edge of such slot and adapted to rest upon a surface to' be cleaned, said lip havin longitudinally extending ribs formed on 51e underside thereof and a groove formed therein, transversely disposed with respect to said ribs and communicating with said slot and main suction chamber.
6. A vacuum cleaner nozzle having a main suction chamber and a slot formed therein having forwardly and rearwardly extending lips adjacent the opposite longitudinal edges, said forwardly extending lip being provided with longitudinally extending Lribs on its underside and said rearwardly extending lip having formed therein adjacent to its rear edge a notch adapted to admit air to said chamber when the nozzle is rocked about said rear edge to raise said forwardly extending lip from the surface being cleaned.
