  • My invention relates to a vacuum cleaner and more particularly to an improved cleaning device for use in connection therewith.
  • one or more brush members are movably mounted within the mouth of a nozzle member and so arranged as to be moved relative to the nozzle body when the nozzle as a whole is moved back and forth over a surface to be cleaned.
  • FIG. 1 is a bottom view of a nozzle in accordance with my invention
  • Fig. 2 is a cross-sectional view taken on the line 2 2 of Fig. 1;
  • Fig. 3 is a cross-sectional view taken on the line 3-3 of Fig. l.
  • reference character I designates a nozzle body, which may be made of wood or metal, and which is provided with an outlet II to which is secured a suction conduit connecting member I2 adapted to be connected to a suction conduit I3. If desired, a rubber Abumper I4 may be disposed around the edge of body I0 in order to serve as a protection against marring furniture or the like.
  • Member I0 is opened at the bottom and has a hollow interior l5 of the shape illustrated in Fig. 1, that is, comparatively wide in the middle and tapered towards each end.
  • Pivotally mounted within space I5 are a pair of brush members IB and I l, each of which carries brush bristles 23.
  • Members I6 and Il include rigid backs and may be pivoted to the body in any desired manner, as by the studs I8.
  • the free ends of members I6 and Il are formed with cut-away recesses I9 and 20, respectively, 'thus permitting overlap' ping of the ends of the members in all pivotal positions.
  • the suction conduit I3 is con- ⁇ nected to a suitable vacuum cleaner unit provided with a'source of suction and a dust sepa- 4rating member.4v
  • a suitable vacuum cleaner unit provided with a'source of suction and a dust sepa- 4rating member.4v
  • the ⁇ bristles 23 carried by brush members I6 and I1 contact the surface and offer a certain amount of frictional resistance to movement thereover. Consequently, when the nozzle is moved in a forward direction, .this frictional resistance causes the brush members to be pivoted to the rear of the nozzle, as shown in dotted-lines in Fig. 1. Movement of the nozzle in the opposite direction causes the brush bristles to be pivoted to the forward part of the nozzle, as shown in full lines in Fig. 1.
  • the brushes are always adjacent to the trailing edge of the nozzle and in a position to dislodge dirt which suction alone has been unable to pick up.
  • the outlet open.- ing Il is unobstructed so that air may ow free thereinto.
  • the brushes is shifted, they pass directly under the outlet opening II, and across the center line of the nozzle where the suction is the greatest and Moreover, each time the position of thus are eifectively cleaned by the inrushlng air.
  • a suction nozzle for cleaning a surface, a hollow body formed with a suction intake opening,'a brush member including a rigid back carrying brush bristles, and means pivotally mounting said brush member about an axis at right angles to the plane of said opening and within said hollow body with said bristles projecting through said opening, said pivotal means being located closer to one end of said brush member than to the other, whereby said brush member is pivoted within said body about Vsaid axis as the nozzle is moved back and forth over the surface.
  • a suction nozzle for cleaning .a surface, a hollow body formed with an elongated suction intake opening, a pair of brush members each in. cluding a rigid back carrying brush bristles, and means for pivotally mounting said members about axes at right angles to the plane of said opening and within said hollow body with said bristles projecting through said opening, one of said pivotal means being located adjacent to one end of each brush member and adjacent to the opposite ends of said elongated opening, whereby said brush members are pivoted within said body about said axes as the nozzle is moved back and forth over the surface.
  • a suction nozzle for cleaning a surface, a hollow body formed with an elongated suction intake opening, narrow at the ends and wider at the center, a pair of brush members each including a rigid back supporting brush bristles, and means for pivotally mounting said members about axes at right angles to the plane of said opening and within said hollow body with said bristles projecting through said opening, one of said pivotal means being located adjacent to one end of each brush member and adjacent to the narrow ends of said elongated opening, the free ends of said brush members being disposed in said wider central portion of said opening, whereby said brush members are pivoted within said body about said axes as the nozzle is moved back and forth over the surface.
  • a suction nozzle for cleaning a surface, a hollow body formed with an elongated suction intake opening, a pair of brush members each including a rigid back carrying brush bristles, and
  • a suction nozzle for cleaning a surface, a hollow body formed with a suction intake opening on one side and a suction outlet opening on an opposite side, a brush member including a rigid back carrying brush bristles, and means for pivotally mounting said brush member about an axis at right angles to the plane of said opening and within said hollow body between said openings with said bristles projecting through said intake opening, said pivotal means being located closer to one end of said brush memberthan to the other, whereby said brush member is pivoted within said body about said ⁇ axis as the nozzle is moved back and forth over the surface.
