  • the vacuum cleaning appliance of the invention is shown in its upright mode of operation and it comprises a main casing 10 which is detachably fitted to the top of the casing 11 containing the electric motor and fan unit.
  • the main casing 10 is provided with a rigid U-shaped carrying handle 12 which is connected at its ends to the opposite side portions 13 and 14 of the main casing.
  • the motor casing 11 is fitted at opposite sides with a pair of supporting wheels 15 (see Figure 3B) for the appliance and the casing also includes an on-off push switch 16 for controlling the operation of the electric motor.
  • a lower cleaner head 7 for engaging a carpet to be cleaned is pivotally mounted on the motor casing 11 so that during use of the appliance the main casing may be pivoted relatively to the cleaner head 17 to allow the passage of the appliance under low furniture such as a bed.
  • the motor casing 11 is provided with an extension 18 which forms a rigid socket for slidably receiving the lower end of a tubular pipe or wand 19.
  • the pipe 19 at its upper end is fitted with a hand grip 20 and forms a handle fbr manoeuvring the appliance.
  • the pipe 19 slidably fits within a stretch, retractable flexible hose 21 which is secured at its lower end around the upper open end of the extension 18 of the casing.
  • the arrangement is such that the pipe 19 when fitted in the socket of the extension 18 enables the handle to be used for manoeuvring the appliance as an upright type machine.
  • FIGS. 3A and 3B of the drawings when taken in conjunction provide a section through the combined casing, 10 11 and 17 of the appliance.
  • this drawing is a section through the main casing 10 which provides a housing for the main cleaner unit which in the preferred embodiment consists of a pair of cyclones 22 and 23 which are located in series in the air flow through the appliance and which operate to remove by centrifugal action the dust and other dirt engrained in the air as will be in hereinafter explained.
  • the cyclones 22, 23 are located respectively in the communicating portions 13, 14 of the casing 10 and are substantially frusto-conical in shape being open at the upper smaller ends for the discharge of the engrained dust and other dirt.
  • the cyclones 22, 23 at their lower larger ends are interconnected centrally of the casing so as to provide an intercommunicating passageway 24 (see Figure 4) for the air flow through the appliance.
  • the passageway 24 is bounded by an upper wall 25 between the cyclones and which have a sleeve 26 extending upwardly therefrom providing a support for a hollow control shaft 27.
  • the hollow control shaft 27 is supported at its upper end by a further sleeve 28 which extends downwardly centrally of the junction of the portions 13, 14 or the casing 10.
  • the shaft extends through the sleeve 28 externally of the casing 10 and is provided with a manually operable control knob 29 by which the shaft is movable both slidably and rotatably within the casing 10.
  • the shaft 27 is slidably movable by the knob 29 into a lower position as shown in Figure 3A in which its lower threaded end 30 is in threaded engagement with an upstanding threaded sleeve 31 formed on the upper surface of the motor casing 11.
  • the cyclones 22, 23 are spaced from the casing 10 to form therebetween and externally of the cyclones a dirt receiving chamber 32.
  • the dust and other dirt removed from the air flow by the first cyclone 22 is discharged over the upper edge of the cyclone and falls into the chamber 32 on to the lower floor of the chamber which is provided by a flange 33 extending outwardly of the cyclones.
  • the flange 33 has a downwardly extending skirt portion 34 which seats snugly within the outer rim portion 35 of the main casing 10 so as to seal the chamber 32, the skirt portion 34 and the rim 35 also engaging a sealing ring 36 carried by the motor casing 11.
  • the cyclone 23 is located downstream of the cyclone 22 and provides a fine or secondary cleaning unit.
  • the cyclone 23 is isolated from the cyclone 22 by forming an independent dust receiving chamber 36 by means of a tubular extension 37 which projects downwardly from the upper end of the portion 14 or the casing 10 so that its lower edge 38 slidably and snugly engages the outer surface of the conical cyclone 23 in its operative position as shown in Figure 3A.
  • the control knob 29 is rotatable to unscrew the threaded end 30 of the shaft 27 from the threaded sleeve 31 on the motor casing 11. This enables the main casing 10 to be removed from the appliance by means of the U-shaped carrying handle 12. The knob 29 is then operable to move the shaft 27 slidably upwards to engage the threaded end 30 with a threaded portion 40 formed on the sleeve 26. When threadably engaged by rotation of knob 29 a downward force then exerted on the knob 29 and thereby the hollow shaft 27, is operable to separate the cyclones 22, 23 from the casing 10 thus opening the chambers 32 and 36 for the disposal of the extracted dust and dirt.
  • the casing 10 and the cyclones 22, 23 are reconnected by unscrewing the end of the shaft 27 from the sleeve 40 by rotation of knob 29, and then depressing the knob 29 to engage the screwed end 30 of the shaft 27 with the threaded portion of the upstanding sleeve 31. Rotation of the knob 29 then threadably engages the shaft and this draws the casing 10 into tight engagement with the flange 34 of the cyclones 22, 23 and also positions the assembly firmly on the motor casing 11.
  • the carrying handle 12 is retained in position on the domed ends of the portions 13, 14 of the casing 10 by connecting bolts, 41, 42.
  • the connecting bolt 42 on the portion 14 of the casing is elongated to support also an additional inverted cone member 43 located in the mouth of the cyclone 23.
  • the member 43 is intended to assist in the final extraction of the dust and dirt from the air flow during the centrifugal movement of the air in the cyclone and as shown this may also be assisted by inclining the outer edge 44 of the cyclone.
  • the arrangement shown, however, is given by way of example only and other designs and arrangements may be used for the cyclone 23 the function of which is primarily the removal of any fine dust or dirt which may have been retained in the air flow after passage through the first cyclone 22.
  • the hose 45 at its upper end is attached to a short rigid pipe 48 which extends through a horizontal plate 49, which plate is attached to and forms the top plate of the motor casing 11.
  • the pipe 48 connects with a curved entry pipe 49' so as to direct the air flow as shown by the arrows into the base of the cyclone 22 in a tangential manner (see also Figures 4 and 5), the air then spiralling up the inner surface of the curved wall of the cyclone to deposit engrained dust and dirt by centrifugal action over the top edge of the cyclone.
  • the air flow then passes centrally down the cyclone into a pipe 50 formed in the top plate 49 and then enters the transverse passageway 24 in which sleeve 31 is located (see Figure 4).
  • the air flow then enters the lower part of the cyclone 23 also in a tangential manner (see Figure 4) and is again processed in the cyclone so as to remove any further remaining fine dust and dirt.
  • the air flow then passes centrally down the cyclone 23 to enter a pipe 51 upstanding from the plate 49.
  • the air flow exits from the pipe 51 into the fan and motor chamber 52 of the casing 11, and is then discharged through an aperture 53 into the cleaner head casing 47 from which it discharges into the carpet through an elongated slot 54 (see Figure 8) formed in the casing.
  • the air flow may discharge directly into the atmosphere from a side slot in the casing.
  • the plate 49 forming the top plate of the motor casing 11 has an outer peripheral flange 55 which seats in the lip 56 of a housing 57 providing the lower part of the casing 11.
  • the plate 49 is attached to the housing 57 by connecting bolt 58 and nut 59, the bolt extending through a chamber 60 which communicates with the inlet pipe 48 by means of an aperture 61 (see Figure 38).
  • the chamber 60 also communicates with sleeve 31 and thereby the interior of the hollow shaft 27.
  • the upper end of the hollow shaft 27 is closed by a plug 62 which is rotatably mounted in the control knob 29.
  • the plug 62 has a skirt portion 63 of varying depth and which is constructed so that as the plug 62 rotates it progressively opens the end of the hollow shaft 27 to atmosphere. In this way the use of the appliance may progressively vent the inlet passageway of the appliance to atmosphere and so vary at will the degree of suction exerted on the carpet being cleaned.
  • This control of the appliance is available whether the appliance is operating in its
  • the casing 11 consisting of the top plate 49 and the housing 57 to which it is connected provides firstly the chamber 52 for the motor 64 and the fan 65, and secondly a chamber 66 in which is mounted a spring loaded reel 67 for the electric supply cable 68 of the appliance.
  • the lower cleaner head casing 47 is elongated in shape and extends across the width of the appliance having a pair of spaced upstanding arms 69 and 70 which are pivotally attached to the casing 11 by means of pivot pin 71 located within slots in the bottom housing 57.
  • the casing 47 is provided with the exit pipe 46 previously mentioned and also formed with a chamber 72 provided by walls 73 upstanding from the casing 47 and which slidably engage the lower wall of the housing 57 around the aperture 53.
  • the cleaner head casing 47 furthermore has a longitudinal open-sided slot 74 in which is located a rotatable brush unit 75.
  • the brush unit comprises opposite sets of bristles and is mounted on a longitudinal shaft 76 pivotally mounted in the end walls 77 of the casing.
  • the shaft 76 also supports the plates 78 which are toothed and one of which comprises a ratchet which is engaged by a pawl 79 during one direction of rotation of the brush unit.
  • the brush unit 75 rotates freely while in contact with the carpet, but during reverse movement as shown in Figure 10 the pawl 79 engages a ratchet tooth 80 on the corresponding plate 78 so as to prevent reverse movement of the brush unit 75 and which thereby provides a brushing effect to the carpet.
  • the opposite sets of bristles preferably pass between spaced plates 81 (see particularly Figure 3) so as to remove therefrom any accumulated fluff and other dirt which is then sucked into the appliance through the pipe 46.
  • the vacuum cleaning appliance of the invention as shown in the drawings is primarily intended for operation as an upright type cleaner, the appliance being manoeuvred by the handle 20 on the end of the tubular pipe 19 which fits the socket in the extension 18 of the motor casing 11.
  • the invention however provides that the appliance may be quickly and simply converted for operation as a cylinder type cleaner and vice versa, merely by the removal and insertion of the tubular pipe or wand 19 in the socket of the casing extension 18.
  • Figure 5 shows the pipe or wand 19 inserted in the extension 18 which provides an open socket 82 for slidably receiving the lower end of the pipe.
  • the socket 82 provides an end seat 83 for the end of the pipe 19, but in its operating mode as an upright cleaner as shown in Figure 5 the end of the pipe is held spaced from the seat 83 by a valve device shown generally by the reference 85.
  • the valve device 85 controls an aperture 84 in the side wall of the socket 82 which communicates the socket with the inlet pipe 48 of the appliance.
  • the valve device is pivotally mounted at 86 on the casing and it comprises a valve member 87 normally closing the aperture 84. At the other side of the pivot point 86 the valve device has an open sided housing 88 in which is mounted a compression spring 89 normally urging the valve device in an anticlockwise direction to open the aperture 84.
  • a switch member 90 is also mounted pivotally on the valve device and is movable relatively thereto. The switch member 90 is formed with a bore which contains a compression spring 94 acting against a slidable plunger 93.
  • valve device 85 pivots anti-clockwise under the action of its spring 89 to the position shown in Figure 7.
  • valve member 87 engages the top edge of the wall of the pipe 48 to allow the plunger to re-engage the opposite side of the line from the pivot point 86 which thus allows anti- clockwise pivotal movement of the switch member 90 relative to the valve device. This sets the switch member for subsequent engagement with the pipe 19 when the pipe is reinserted in the socket 82 for conversion to the upright mode of operation of the appliance.
  • the pipe or wand 19 is slidably mounted in hose 21 and at its inner or lower end it is fitted with a fixed sleeve 96.
  • the hose 21 is connected at its lower end to the socket 82 by a cuff 97, the hose having a PVC sleeve 98 bonded to the cuff.
  • the upper end of the hose includes a further PVC sleeve 99 bonded to the cuff 95 which includes a felt or similar seal 100 in sliding contact with pipe 19.
  • pipe 19 is shown in the inserted or upright mode of operation of the appliance.
  • the pipe 19 In order to re-convert the appliance for upright mode of operation the pipe 19 is merely reinserted slidably within the short upright tubular casing 82.
  • the manoeuvre is generally facilitated by closing the open end of the pipe handle 20 while the fan is operating, the resulting suction action to straighten the hose 21 which enables the pipe 19 to be slidably moved therein without difficulty.
  • a particular advantage of the vacuum cleaning appliance of the invention is that no dust bags are required, the dirt being discharged from the appliance by separating the cyclones from the main casing.
  • the use of a cyclone ensures that the dust discharging from the appliance is substantially dust-free and a particular advantage of the use of a cyclone is that during use the dust laden air does not pass through the previously extracted dirt thus avoiding the possible discharge of smells from the removed dirt. Filters are therefore avoided and the use of a cyclone permits the entry into the appliance of articles which would normally cause damage, such as glass and water.
  • the discharge of the dust-free air into the cleaner head helps to dislodge engrained dirt during cleaning and is more efficient than rotating brushes as the air penetrates more deeply into the pile of the carpet and so dislodges dirt and grit which is firmly engrained in the pile. Furthermore, the discharge of the dust-free air as jets into the carpet effectively muffles the fan which greatly reduces the noise during cleaning.
