Definitions

  • the present invention relates to suction or vacuum cleaners for cleaning and dusting and has for its object to provide an improved suction cleaner for cleaning by suction and agitation.
  • the suction hood of towards the end of the upward movement of the member to permit outside air to enter side suction hood and eflect a change of pressure therein to cause downward movement oi! the agitator member.
  • Fig. 1 is a section on line I-I-of Fig. '1 showing ,the suction nozzlef the agitator and the adjacent suction tube of an improved vacuum cleani Fig. la shows in detail the flexible strip, the adjacent parts of the'nozzle'and th'e agitator.
  • Fig. 2 is a plan view oi! the agitator plate seen in the direction of the arrow A oi! Fig. 1,
  • Fig. 3 is a section on line III-III of Fig. 1,
  • Fig. 4 is a section'on line IV--IV of Fig. 5,
  • Fig. 5 is a section on line V-V 01' Fig. 4,
  • Fig. 6 is a section similar to that in Fig. 1, but showing a brush applied to the agitator plate, and
  • Fig. 7 is a section-on line VlIVII of Fig. 6.
  • a plate 4 Upon the under surface oi the agitator member 3 is detachably fixed a plate 4.
  • This plate 4 has raised portions 4a andintermediate depressed portions 4b.
  • the opening 40, 3b eflects communication between the outer air and the suction chamber If.
  • Other openings 4d connect the space under the plate 4 with an outer space which is within the path of the air current mov- 5 'ing past the flexible strip.
  • the thread catcher 5 consists of a rubber strip the upper part of which is held in a sheet metal mount; 10 the latter has projecting ends which enter into the recesses 46. The thread catcher cannot drop out of the recesses because it'is secured in its position by means of two transverse webs 6.
  • thread catchers are very well known in connection with suction cleaners.
  • the thread catcher is held in the agitator by means of two transverse webs 6, and therefore cannot drop out of the recesses 4e.
  • 1 indicates a slide which is continuous around the housing which encloses the outer side of the parts la and lb of the suction nozzle, and is provided with beads la fitting corresponding grooves lg formed in the outer side of the suction hood. The slide may be moved by hand so that the beads la engage one or the other of the grooves lg and thereby raise the cleaner at different heights from the floor.
  • ll indicates a brush adapted to be applied to the undersideof the plate 4.
  • the brush may 3 be fixed to the plate 4 by any suitable device.
  • cylindrical pivot lc is provided with a suction port it and is enclosed by a socket member 8, the latter being'secured in position upon the pivot by means of two covers 9 provided with flanges 9a.
  • the pivot pin I0 is provided at both ends with recesses llc in which are lodged springs the lower ends 01. which bear against the flanges 9a of the covers, whereby the cylindrical pivot to is constantly pressed against the upper part 40 of the socket 8.
  • the openings 9b in the covers 8 through which the fixing screws l3 pass, are elongated in the vertical direction to enable the covers 9 to adjust themselves automatically with regard to the pivot pin under the action of the 4'5 springs 9 to compensate for the wear of the socket 8 or the pivot pin lo, the joint between the socket 8 and the pivot pin lc being airtight.
  • the agitator will exert a beating action upon 5 vacuum being produced in the vacuum chamber l! of the suction nozzle.
  • the vacuum draws the agitator member 3 together with the free por-- tion of the flexible strip upwards, until the latter detaches itself from its supporting flange la and snaps back.
  • the vacuum in the vacuum chamber is at least partly released and the agitator member is returned to its initial position by its own weight and by the action of the springs l2. Rapid repetition of this operation produces vibrating movement of the agitator.
  • the described apparatus may be used for various purposes.
  • the cleaner In the position shown in Fig. 1 the cleaner is used for beating and simultaneously vacuum cleaning soft supports such as carpets, cushions, fabrics and the like.
  • the opening 3b which is enclosed by the raised portions 40 on the plate 4 is substantially sealed by the support.
  • the agitator is raised air passes through the openings Ih past'the flexible strip 2 into the suction nozzle taking with it the particles of dust dislodged by the agitator.
  • the opening 3b becomes free and draws in a certain amount of dust-laden air whilst dust particles dislodged underneath the plate are also a guided by the raised portions of the plate into the openings 4d formed therein and from thence into the suction nozzle.
  • the upper bead of the slide I which latter is made of a resilient material, for instance rubber, into the middle notch of the suction nozzle, and on detaching the plate 4 from the agitator member 3, and thereby causing the opening 3bof the agitator member 3 to lie freely upon the support to be cleaned, vacuum in the vacuum chamber If 9 will be partly released owing to the fact that air will freely flow from the soft support into the space If, and the cleaner will now work with suction only. The air will then not-pass past the flexible strip and there will beno beating action.
  • the apparatus may also be used for brushing and polishing hard supports such as parquet and inlaid floor or like excessively reduces the suction action, the upperbead of the slide 1 should in this case be inserted into the lowermost notch of the suction hood lb.
  • the agitator 3 is fixed at one end by means of pins lm and during beating oscillates about this edge in a manner similar to a door turning on its hinges.
  • the under face of the agitator member 3 adjacent to the floor or other support is preferably so shaped as to slope downwards from its axis of oscillation, so that this surface will lie during vibration approximately parallel with the lower edge of the suction hood.
  • agitator member 3' might be made adjustable in size and also be provided with closure means.
  • the plate 4 preferably consists of material in which electricity of friction can be produced. 5 Such materials are, for instance, hard rubber. rubber, artificial resin, Bakelite, ebonite and so on. This material assists the suction as dust particles are attracted by the electricity of fric-, tion produced during the cleaning'movement- Instead of flxing the brush II to the underside of the plate 4, the brush might be fixed direct to the under side of the agitator member 3.
  • a suction cleaner comprising a housing having a vacuum chamber therein, a suction nozzle connected to the housing, an inwardly extending flange on the nozzle, a flexible strip connected to said flange and extending beyond the flange, an agitator having a flange resting onthe free edge portions of the strip to prevent the admission of air.
  • a suction cleaner comprising a housing having a vacuum chamber therein, a suction nozzle connected to the housing, an inwardly extending flange on the nozzle, a flexible strip connected to said flange and extending beyond the flange, an agitator swingably connected to the nozzle and having a flange resting on the free edge portions of the strip to prevent the admission of air to the vacuum chamber when the flange of the agitator is in contact with the flexible strip and to admit air to break the vacuum in the vacuum chamber when said flange is raised above the strip by suction in the vacuum chamber, and means to cause the'return movement of the agitator.
  • a suction cleaner comprising a housing having a vacuum chamber therein, a suction nozzle connected to the housing, an inwardly'extending flange on the nozzle, said nozzle having an edge which is adapted to be brought into conchamber when the flange of the agitator, is in contact with the flexible strip and to admit air to break the vacuum in the vacuum chamber when said flange is raised above the strip by suction in the vacuum chamber, and means to cause 5.
