  • Dust collecting compartments I9 and 19 are provided in front of and to the rear of the first roller brush 5 and in proximity thereto.
  • the above mentioned is a construction of a typical conventional rotary type carpet sweeper.
  • a first dust removing brush member 10 which is slidable horizontally on guide rails 14 and 14' back and forth between an end frame b of the main body A and a stopper wall 17 positioned above the dust collecting compartment 19.
  • the first dust collecting member 10 has numerous inclined short bristles 12.
  • the guide rails 14 and 14 are connected to and extend along the opposite side walls of the inner frame 0 (see FIG. 3).
  • the first dust removing member 10 is a secondary dust removing stationary brush member 1 l fixed, at its opposite ends, to the opposing side walls of the inner frame c.
  • the second dust removing member 11 is provided at its face with numerous inclined bristles 13 engageable with the bristles 12 on the first dust removing member 10.
  • the bristles l2 and 13 are inclined in the same direction, i.e., to the left, as are the bristles 8 on the second roller brush 7.
  • a cushioning plate 15 In contact with the upper face of the first dust removing member 10, there is provided a cushioning plate 15 within which is arranged an elastic sponge or like sheet material 16.
  • This plate 15 with elastic sheet 16 is interposed between the main body cover 18 and first dust removing member 10, so as to make it possible to elastically automatically adjust the sliding relation of the first dust removing member 10 with respect to the second roller brush 7 and also relative to the second dust removing stationary member 11.
  • Indicated with 21 is a handle which is pivotable around a connecting pin 20 by the operator.
  • the second roller brush 7 rotates in the counter-clockwise direction at a reduced speed, while pushing the first dust removing slider member 10 toward the stopper wall 17 by the frictional contact between bristles 8 and 12. Since the bristles 8 on the outer peripheral surface of the second roller brush 7 are inclined in the counter-clockwise direction, the bristle 8 merely slide along the surface of the carpet in a slipping manner when the main body A travels in the direction of the solid arrow. Accordingly, the first roller brush 5 alone performs cleaning during the first forward movement of the sweeper or when the main body A moved forward direction of the solid arrow shown in FIG. 1.
  • the drive wheels 1 and 1' rotate in the direction opposite to that of the dotted arrow, permitting the first roller brush 5 to sweep up relatively coarse dust from the surface of the carpet into the dust collecting compartment 19 with its bristles 6 while being driven by the driven wheel 3 in the direction of the dotted arrow.
  • the second roller brush 7 rotates in the clockwise direction or in the direction opposite to that of the dotted arrow, namely opposite to the direction of advance of the main body A.
  • the fluff, lint or fine dust caught among the group of inclined bristles 8 is raked off and taken up by the bristles 12 on the face of the first dust removing member 10 (now stationary due to engagement with the frame b) as if by combing, this rendering the bristles 8 on the second roller brush 7 clean and ready for the subsequent brushing operation.
  • the first roller brush 5 sweeps relatively coarse dust and the like from the carpet into the dust collecting compartment 19' as already described with respect to the first forward movement of the sweeper, while the second roller brush 7 rotates at a reduced speed while simply sliding on the carpet in a slip ping fashion.
  • the first dust removing member 10 is advanced to the position of the stop wall 17 due to the frictional engagement with the roller brush 7 and is then stopped as it abuts the stop wall 17.
  • the bristles 12 on the under face of the first dust removing member 10 are inclined in the same direction as the bristles 13 on the upper face of the secondary dust re- 7 without being combed off by the bristles 13, although the bristles 12 and 13 are in contact with each other during this forward movement of the member 10.
  • the first roller brush again sweeps up relatively coarse dust from the carpet into the dust collecting compartment 19. While the second roller brush 7 takes up fluff, lint or fine dust from the carpet into the bristles 8, the first dust removing member moves backward in contact with the brush 7 stops at the position of the end frame b, thereby permitting the bristles 12 on the first dust removing member 10 to take off the dust and the like retained in the bristles 8 by combing as already described.
  • the dust and the like caught among the bristles 12 during the preceding backward travel are scraped off by and transferred into the bristles 13 on the secondary dust removing stationary member 11 by combing by virtue of the engagement between the bristles 12 and 13.
  • the dust and the like thus lodged among bristles 13 are then pushed forward by the subsequent forward movement of the first dust removing member 10, and eventually discharged into the dust collecting compartment l9 automatically.
  • the bristles 6 on the first roller brush 5 sweep relatively coarse dust from the surface of the carpet into 19 and 19 respectively, whereas the second roller brush 7 takes up fluff, lint or relatively fine dust remaining on the carpet only during the backward movement.
  • the dust or the like taken up by the second roller brush 7 is then raked off from the bristles 8 and transferred to the bristles 12 on the first dust collecting member 10 which is in sliding contact with the bristles 8.

  • the dust or the like retained among the bristles 13 is progressively pushed out by the bristles 12 and finally discharged into the dust collecting compartment 19 automatically.
  • the carpet sweeper according to this invention disposes of relatively coarse dust by utilizing the characteristics of the conventional bristle roller brush.
  • fluff, lint or relatively fine dust adhered to the pile surface of carpet which can not be removed by the conventional type of bristle roller brush 5 is caught by the inclined bristles 8 on the second roller brush 7 and is ultimately pushed into the dust collecting compartment automatically.
  • the drawback of the conventional carpet sweepers can be eliminated.
  • the position of the first roller brush 5 relative to the second roller brush 7 will be reversed. If the handle 21 in this position is pushed to advance the main body A in the direction of the dotted arrow, the first roller brush 5 will achieve exactlythe same result as explained before. However, the operation and effect of the second roller brush 7 will be exactly the reverse of the above description. Thus, the cleaning operation is conducted only during the forward movement of the sweeper. More specifically, the advance of the main body A in the direction of dotted arrow rotates the second roller brush 7 at a reduced speed as if being dragged on the carpet due to the friction with the first dust removing member 10.
