Definitions

  • This invention relates to dust separators for vacuum cleaners.
  • Fig. 2 is an enlarged cross-sectional view of la detail
  • Fig. 3 is a view looking into the cover of the vacuum cleaner with the dust separation cloth removed;
  • the vacuum cleaner illustrated includes a. cylindrical barrel 10, of metal or other air impermeable material, which is removably supported, with its axis vertical, on a lower frame member 12.
  • a motor 11 is supported on frame 12, also on a vertical axis.
  • the motor is provided with a housing lla, having a plurality of heat radiating fins formed thereon, over which the main air current of the cleaner is adapted to pass.
  • a multi-stage centrifugal fan or blower 17 is mounted on the motor shaft for drawing air over said motor and forcing the air to a discharge chamber llc, from which air is discharged through a plurality of louvers 11d or through a blower opening 21, suitable valve mechanism being provided, for this purpose.
  • the motor is enclosed in a shield 23 having a perforated top and which is spaced from housing 11a.
  • a central air tube 15 is mounted within barrel 10 in alignment with said motor and is provided with an enlarged section 16 which is adapted to 00 pass over shield 23.
  • the parts 10 and 15 are joined at the bottom and together form a dust collector.
  • a roll packing 24 is located between shield.l 23 and the enlarged section 16 to provide an air and dust seal. The arrangement is such that the dust collector 10, 15, 16 may be removed from the frame 12 in order to be emptied without disturbing or exposing the motor.
  • Frame 12 is mounted on wheels 18 and 19, by
  • .A handle 22 is mounted on cover 13, and is se- 80 cured thereto by spacing members 28 and .bolts 29, which parts are sufliciently rigid in construc-A tion to permit the entire cleaner to be moved thereby.r
  • Bracket 27 serves as a mounting for a support 30 for holding an inner end retaining ring or annular member 26 of a dust separation unit presently to be described. Parts l 27 and 30 may be secured together by rivets.
  • a 90 roll packing 25 is provided between tube 15 and annular member 26 to provide an air and dust seal and at the same time to permit said member 26 to be readily applied to or removed from said tube.
  • a pair of holding members 40 are also mounted on the cover 13 as by the bolts 29, and carry a ring 41 which is supported thereby in a xecl position.
  • -Rings 38, 39 and 41 are preferably formed of metal strips which are bent in circular form without sharp edges which would injure the separator cloth.
  • the dust separation unit comprises a cloth dust separation member 42 which is made in the form of a truncated cone as illustrated in Fig. 4 and is secured to annular member or inner ring 26 and an outer end retaining ring 43 by any suitable means, such as string or riveting or the like.
  • Ring 43 is provided with a lateral flange 43a, which carries a packing member 44 of rubber or similar elastic material.
  • Packing member 44 is adapted to engage a ringshaped flange or offset portion 45 on cover 13, and is secured between said flange and the upper part of the dust collector 10.
  • Annular member 26 with the dust separation member 42 attached thereto is adapted to slide over support 30 into the position shown in Fig. 1.
  • Support 30 is provided with spring portions 46, which are adapted to engage or snap into depressions in ring 26 for maintaining the same in assembled position. Said spring portions 46, however, may be omitted, if desired, and annular member 26 may loosely engage the support 30.
  • Cloth member 42 may be secured to rings 38 and 39 by split clamping rings 47 which are preferably so dimensioned that the rings may be applied by causing the ends to overlap and may be locked by extending the same to bring their ends into mutual engagement, and to thereby clamp the cloth member 42 between said rings and the annular flanges 48 and 49, respectively, of rings 38 and 39.
  • the cloth is folded or plaited so that it has a zigzag crosssection, as shown.
  • the edges of folding are circular.
  • the upper edges are in the same plane; likewise the lower edges are in the same plane.
  • the lower surface of the dust separation member may tend to become clogged with dust or other material which would eventually interrupt the operation of the machine if it were allowed to accumulate thereon.
  • dust or other material which would eventually interrupt the operation of the machine if it were allowed to accumulate thereon.
  • cap 35 may be readily removed by alternately pressing and releasing cap 35 (preferably quickly so as to give a snap action), whereby rings 38 and 39 are moved and vibrated and cause a corresponding movement and vibration of the cloth surface.
  • rings 38 and 39 are moved and vibrated and cause a corresponding movement and vibration of the cloth surface.
  • spring 37 causes the above members to snap back into their original position and thereby compress the air within said chamber and cause a flow of air through the dust separation member in the direction opposite to the normal flow during operation of the machine.
  • This air current assists in removing the dust particles from said dust separation member.
  • the above action is in part accomplished due to the fact that the air resistance of the motor enclosure and fan 17 is greater than the air resistance of the dust separation cloth.
  • the dust separation member may be vibrated so as to provide pulsations of air therethrough.
  • the vacuum cleaner may be operated for indefinite periods of time without requiring removal or replacement of the dust separation member, the operation being interrupted when necessary to remove the cover and empty the dust collector.
  • stem 33 is shown as carrying a pair of cross-bars 50 and 51. Said bars extend through a tube 52 whichis secured to cover 13 and is provided with slits 54 in which said bars are adapted to slide.
  • the lower part of tube 52 carries a cross-member 53 through which rod 33 is Loiseau guided.
  • spring 37 is seated and serves a purpose similar to that described in Figs. 1 to 4.
  • Tube 52 is also provided with slits 55, which permit the free passage of air therethrough.
  • Resilient clamping means 56 are f mounted on members 50and are adapted to receive the cloth member 42.
  • a support for a folded, conical dust separation member comprising end retaining rings, movable rings supporting intermediate folds of said member, and split clamping rings for clamping said member to said movable rings.
  • a support for a dust separation member comprising an annular member comprising an annular ring portion having an annular flange secured thereto and a clamping ring engaging said flange and ring portion for clamping a cloth member therebetween.
  • a vacuum cleaner of the vertical type having an annular dust collector and an internal, axially extending air pipe, a cover for said dust collector, and a dust separation member mounted between said dust collector and said cover, said member being folded into zigzag form, means to normally produce now ofv air through said dust separation member to said air pipe, a plurality of means for supporting the folds of said member, certain of said means being movable for shaking said member and compressible means adapted to be quickly released for causing a counter-current of air to pass through the dust ⁇ separation member due to expension of the compressible means during the shaking operation.
  • casing member a cover mounted thereon, a plurality of lower concentric supporting rings and a plurality of upper concentric supporting rings mounted in said cover, said upper rings being movably mounted, a dust separation member lfolded back and forth between said upper and lower rings, means for normally passing dustladen air upwardly through said dust separation member to deposit dust on the under side thereof, and resilient means associated with said upper rings for normally maintaining said dust separation member under tension.
  • a vacuum cleaner having a casing memi ber, a cover mounted thereon, a dust separation member, concentric end retaining rings carrying said dust separation member, means associated with said cover for supporting said rings, an intermediate movable ring engaging said dust separation member, and means to maintain said movable ring and thereby said dust separation member under tension, the tension being in such direction that said end retaining rings are held ma within said cover thereby.
