Definitions

  • the top of the dust bag is closed by means of a plate member, which may be of stiff cardboard, and the member is provided with an aperture.
  • a plate member which may be of stiff cardboard, and the member is provided with an aperture.
  • the diaphragm has an aperture which is in register with the aperture in the plate, but is of smaller size, and to achieve the seal connection between the inlet tube and the dust bag, the inlet tube end is simply forced through the aperture-in the diaphragm, and the expansion of the diaphragm aperture and its resiliency effects a seal against the inlet tube. This seal is necessary to prevent the escape of dust, fluff and other material collected by the vacuum cleaner bag.
  • the flexible sheet diaphragms referred to above are epxensive, and cost almost as much as the plates to which they are attached.
  • the labour cost involved in applying the diaphragms to the plates is substantial, and as a result, the plate and diaphragm is an expensive item of the whole dust bag.
  • any small cost saving per bag will represent a large saving in total.
  • the rubber latex or the like is applied in liquid form as a coating extending over the edge of the aperture, and the liquid latex or the like which overlaps the aperture is supported by a metal insert.
  • the coating may be applied by spraying a jet of the material radially towards the centre of the aperture and by rotating the spraying device through 360° thereby to form a ring of the coating which overlaps the metal insert and overlaps the sealing member to which the coating becomes bonded when it has cured.
  • the metal insert can be removed to leave a diaphragm of the rubber latex or the like material extending across the aperture.
  • the head has two side by side outlets from which drips issue simultaneously, and subsequently coalesce when they land, with adjacent drips to provide a continuous ring of latex.
  • a vacuum cleaner dust bag comprises three components namely a filter bag 10 which is closed at the bottom (not shown) end, a closure plate member 12 which also forms the means for location of the dust bag in the vacuum cleaner, and a flexible sealing diaphragm 14 which is in the form of a thin sheet of rubber latex.
  • the plate member 12 has an aperture 16 for receiving the end of the vacuum cleaner inlet tube, and the diaphragm 14 has an aperture 18 of smaller size than aperture 16, and through which the end of the inlet tube is forced to provide a seal as will be explained.
  • Fig. 2 shows the completed dust bag, and it will be seen that the filter bag 10 is in fact flattened and the bottom end is sealed by folding same on itself and adhering the fold portions one to another.
  • the bag As shown in Fig. 2, it is inserted in the appropriate position in the vacuum cleaner, the plate member 12 forming the location and support means for the bag, and the inlet tube is simply pushed through aperture 18 and the'diaphragm, which expands and by its resilience forms a seal around the tube end.
  • the motor 38 is stopped by sending a signal over control line 56, the pump 50 is caused to supply composition to the heads 44 via a control signal over line 58, and finally a further control signal is sent over line 60 to a displacement device 62 in the form of a piston which displaces a horizontal rack 64 which co-operates with each of the heads 44 in a manner to rotate the dispensing portion for the effective distribution of the composition as will be explained hereinafter.
  • Fig. 5 by virtue of the surface tension of the composition it takes up a humped cross-section tapering to substantially zero thickness at the inner and outer edges 80A and 80B, and when the holder the plate and composition pass through the oven chamber the composition cures to form a flexible diaphragm of substantially the same shape as illustrated in Fig. 7, the cured composition bonds to the plate but not to the insert.
  • Fig. 6 also shows the plate with the composition applied, but in perspective elevation.
  • any suitable composition to provide a flexible diaphragm may be provided, but a preferred material is a latex composition sold by under the name , and the applicator heads preferably are set to rotate at a speed of revolutions per minute with a composition drip rate of cc per revolution.
  • the cure time for composition applied to such quanity is in an oven chamber maintained at a temperature of .
  • the resulting plate members with the flexible diaphragm are attached to the dust bags by conventional means.
  • the manner of functioning of the mould can be readily understood, because the mould parts are shown in assembled relationship with the plate member 100.
  • the recess,118 forms a cavity 120 to which the composition, again suitably rubber latex, can be injected through passages 122 in the member 104, and 124 and 126 in the, member 102.
  • Passage 124 is an axial passage located centrally of member 102, and leads to radial distribution passages 126 to ensure that when the latex is injected through passages 122 and 124, it is evenly distributed throughout the cavity 120.
  • the cavity 120 is defined partly by the top surface of the plate member 100, and partly by the top surface of intermediate section 108 of the male member 102.
  • the surface tension effects on the rubber latex or the like material as related to contact with the metal of the washer 104X ensures that the coating flows freely on the washer, and as the spraying device 108X is rotated as indicated by the arrow 114X, so an annulus of the coating as shown in Fig. 13 is formed which overlaps an edge region of the plate member 100X and becomes adhered thereto and also overlaps the washer 104X, as shown in Fig. 12.
  • the annular coating 116X has been cured, (for example as described previously), the washer 104X is removed leaving the arrangement as shown in Fig. 13 in which the coating extends across the edge 102X defining the plate aperture thereby to provide a diaphragm which is substantially as shown in Fig. 7 and which acts as a seal upon a tube or conduit of larger diameter than aperture 106X and inserted into the aperture 106X of the diaphragm.
