1 Claim.
This invention relates to suction cleaners of the type employing a disposable dust-collecting bag which, after being filled to the proper level, is replaced by a fresh bag, and an object is to improve and simplify suction cleaners of this type enabling the adoption of an inexpensive dust-collecting bag which can be readily and conveniently mounted or removed without the use of special tools or appliances.
Another object is to produce a simple and ef' ficient dust-collecting bag for suction cleaners which is simple in construction, inexpensive to manufacture, and is adapted to be conveniently attached or removed from the suction cleaner.
Other objects and advantages of the invention will hereinafter appear, and for purposes of illustration but not of limitation, an embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a perspective view of a suction cleaner;
Figure 2 is an enlarged vertical sectional elevation of the upper portion of the suction cleaner shown in Figure 1 showing a portion of the dustcollecting bag and its connection to the under side of the hinged cap; and
Figure 3 is a side elevation of the dust-*collecting bag.
The illustrated embodiment of the invention comprises a suction cleaner having a base It containing an electric motor (not shown) controlled by a switch button II, the motor operating a suction fan which draws air through a nozzle H2 in the cap :3. The cap I3 closes the open upper mouth or a casing is. It will be understood that a fiexile hose (not shown), is connected to the nozzle i2 and such hose is connected at its opposite end to the usual wand carrying the hoor tool. Detail illustration and description Of the suction cleaner is not considered necessary to a full understanding of this invention, the above being sumcient generally to describe the wellknown suction cleaner structure. In this instance the cap 13 is ningedly connected at l5 to a sleeve it which is suitably secured to the upper edge portion of the casing Hi. Integral with the inside of the cap 13 is an annular flange ll which is adapted to bear against a rubber sealing ring 13 when the cap is closed. The cap is securely held in its closed position by a suitable latch I5.
The nozzle I2 is swivelly mounted on the cap I3 so that it may be readily turned from one position to another and in alignment with the inner end of the nozzle 82 is a second noZZle or tube 26,
the upper end of which is flanged outwardly and secured to the cap by screws 2|. The lower portion of the nozzle is somewhat reduced in diameter as indicated at 22, and adjacent the lower end of the tube 29 is an inwardly extending annular groove 23.
Fitting the inwardly extending nozzle or tube 20 is a neck portion 24 of a dust-collecting bag 25. The bag is retained on the reduced portion 22 of the nozzle 20 by an annular coil spring 26 which resiliently urges the engaged portion of the bag neck 24 into the annular groove 23. When it is desired to remove the bag 25, the cap I3 is tilted about its axis I5 sufficiently to enable the spring 26 to be slipped upwardly to clear the free end of the bag neck 24 whereupon the neck may be slipped outwardly from the reduced nozzle portion 22.
The dust-collecting bag 25 is of air pervious sheet material such as paper, such as to enable the dust free air to pass through the walls of the bag, the interstices, however, being such as to retain the dust and foreign matter within the bag. Preferably when the bag is in operation, the walls extend outwardly into engagement with or close proximity to a foraminous sleeve 27 which is preferably spaced from the inner wall of the casing M, the upper end of the sleeve 27 being flanged outwardly and suitably secured in Place. Thus the air, after passing through the walls of the bag 25, may pass through the openings in the sleeve 2'! and through the space between the sleeve 27 and the inner wall of the casing, and be suitably discharged through a suitable opening (not shown) in the base of the cleaner. It will be observed that the casing I4 is formed with a series of longitudinal flutes and air passes between the flutes, as will be readily understood.
As shown in Figure 3, the bag 25 may be formed from a continuous tube of paper formed by folding a strip of sheet material upon itself and adhesively securing the free ends along the seam 28. The continuous tube thus formed is then severed in such manner as to provide the reduced neck portion 24 and formed with sewed seams 29, 30 and 3| to provide a closed bag except for the open end of the neck 24. Means other than sewed seams, such as adhesive or tape, may be employed to effect the closed seams, it being desirable to produce the bag as inexpensively as possible and still produce seams which will militate against the passage of dust from the bag during the operation of the suction cleaner.
From the above description, it will be manifest that I have produced an exceedingly simple and inexpensive device for collecting the dirt in a suction cleaner. The bag can be manufactured inexpensively in quantity production, and can be easily applied and secured in position of use. Furthermore, the bag can be removed in an extremely simple manner and after being removed, the neck may be folded to insure against spilling of the dirt contained Within the bag.
It is to be understood that numerous changes in details of construction, arrangement and ope-r ation may be efiected without departing from the spirit of the invention especially as defined in the appended claim.
What I claim is:
The combination of a suction cleaner having a casing provided with an open mouth, a cap closing said mouth, wall means on said cap to register with said casing mouth, means to effect an airtight seal between said wall means and casing mouth, means hingedly connecting said cap to said casing, conduit means on said cap through which dust la-den air is adapted to pass into the casing, nozzle means on the inside of said cap 2 and communicating with said conduit means, a reduced inner end portion on said nozzle having an annular groove adjacent the free end thereof, an air pervious bag of sheet material within said casing, said bag having a closed end and side Walls, a reduced neck integral with the other end of the bag fitting said nozzle, and an annular spring for clamping said bag neck to said nozzle means and fitting said annular groove, the bag being released by slipping said spring out of said groove and along said reduced end portion to clear the bag neck.
