Definitions

  • the present invention relates to suction cleaners in general and particularly to new and novel improvements in means to reduce the noise of cleaner operation. More specifically the invention comprises a suction cleaner in which no relative movement takes. place between the cleaner exhaust outlet, the cleaner dust bag, the cleaner handle, and a rigid muiiier element,
  • a still-further object is the provision of a-suction cleaner having a mufiier which extends. within the cleaner dust bag and which expands therein.
  • Figure 1 is a side view of the suction cleaner constructed in accordance with the present invention, certain parts being broken away;
  • Figure 2 is a partial side view of the cleaner with the and muilier unit removed there-,
  • Figure 3 is a front elevation certain parts being broken away, of the body of the cleaner shown in Figure 1;
  • Figure 4 is the cross-section through the- Figure 10 is a section through the muiiier of Figure 8 upon the line l0ll
  • Figure 11 is a section throughthe muiiier element of Figure 8 upon the line ll-I I; 1
  • the cleaner nozzle I is mounted upon a frame which is supported by spaced pairs of front and rear wheels 2, 2 and 3, 3, respectively.
  • the driving motor 4 is positioned with its'axis parallel to the nozzle Land its shaft carries at one end a pulley 5, and at its opposite end a suction-creating fan 6.
  • a power-transmitting belt 1 connects the pulley 5 to a rotating agitator 8 within the nozzle I, while the fan 6 is effective, in the operation of the cleanerytoereate a reduced pressure in nozzle I through being directly connected thereto.
  • the combination motor casing and fan chamber l carries the motor 4 and fan 6' and is itself rotatable about the motor axis through being provided with sealed bearings I 0 and -l l' at its opposite ends on the rearwardly-extending side channels of the nozzle I.
  • the exhaust outlet I! of the fan chamber is formed rigidly on the casing 9 and is provided at its end with a flange and bag-clamping means iii.
  • the handle of the cleaner is indicated by the reference character l4 and is rigidly'connected to the casing 9, as shown in Figures 1 and 2.

  • the open-upper end of the bag is folded and held in a closed and sealed relationship by means of an enclosing U-sh aped chanmetallic casing 22 and an inner liner or sleeve 23 of sound-absorbing material such as felt or sponge rubber which extends substantially the entire length of the outer body 22.
  • a collapsible valve '25 preferably of cloth or fabric.
  • Valve functions, in the operation of the machine, to prevent, by collapsing to close the end of the mufller, the return into the muifler of foreign matter by 'an air current set up by the bag back pressure when the suction-creating means or fan has ceased to rotate at the 'end of a cleaning operation.
  • a second preferred embodiment of the' invention is dis closed.
  • the muwerr is indicated by the reference character 26 and is secured integrally to theexhaust outlet 2 of the cleaner by means of rivets 21, 21.

  • the bag 32 telescopes downwardly and encloses the muiller 26 being provided with'a second lower bag ring 34 at a a point adjacent the outer end of the exhaust outlet serve to seat and lock the ring 34 in place.
  • This construction has the advantage that the bag may be removed without removing the muffler by disconnecting the two bag rings. 84 and 3
  • the upper end of the bag is supported from the cleaner handle as in the first embodiment.
