Definitions

  • My invention relates to vacuum cleanersa nd more particularly to an improved suction nozzle.
  • a nozzle having an elongated suction opening adapted for use in removing ordinary dust and dirt from a rug, or other surfaces to be cleaned, and which is provided with a pivoted member which may be swung into a position for reducing the effective cross-sectional area of the nozzle opening. This serves to concentrate the air flow at a comparatively small area, thus making the nozzle effective ior removing threads, dog or cat hairs, or other smaller objects which adhere tenaciously to the surfaces being cleaned.
  • the pivotal member In order to reduce the effective cross-sectional area of the nozzle the pivotal member is arranged to be swung into such a position that it blocks a considerable proportion of the area of the nozzle opening. When in this position the'effect of the suction is to retain it, thus reducing the ease with which it may be returned to its originalposition when it is desired to make use of the full cross-section of the nozzle. opening.
  • means are provided whereby the strongsuction which tends to hold the pivoted member in a position reducing the cross-sectional area-of the nozzle opening is broken by merely lifting the nozzle 'from the surfaces being cleaned, thereby permitting thefimember. to be returned toits inoperative-position.
  • Fig. 2 is a cross-sectional view taken on the line 2-2 of Fig. 1;
  • Fig. 3 is a view similar to Fig. 1, but with certain parts in a different position;
  • Fig. 4 is a cross-sectional view taken on the line L4 of Fig. 3;
  • Fig. 5 is a bottom view of a portion of a nozzle in accordance with a second embodiment of my invention.
  • Fig. 6 is a cross-sectional view taken on the line 6-5 of Fig. 5;
  • Fig. 7 is a cross-sectional view taken on the line 1-1 of Fig. 5.
  • reference character I! designates a nozzle body which is formed with an elongated suction opening M.
  • Thi opening is bounded in part by forward lips Ill and it and rear. lips All and it, the ends of lips it and it and lips ill and it being joined together at the ends of the nozzle.
  • Rotatably secured. to the nozzle. body ill is a hollow cylindrical-member it formed with an opening Illwhich establishes communication between the interior of thebody it and the interior of the member it.
  • aconnecting member l8 Secured to'the member lb and communicating therewith is aconnecting member l8, the opposite end of which is adapted 10 to receive a conduit leading to a source of suction.
  • the space between the forward lips l2 and i3 provides a narrow slot l9.
  • the depth of the interior of the nozzle body is indicated by the distance a, while opposite the slot E9, the depth of the interior of the nozzle body is limited only by the member 06..
  • This member is formed with a lip 2! which, when the member is in the position shown in Figs. 1 and 2, forms a continuation of the rear lips M and 15.
  • Member is formed with a central opening-22 and this opening, on the opposite side of the member from the lip 2
  • the lateral dimension of the member 20 is such that, when it is swung to the position shown in Figs. 3 and 4, a narrow passageway 24 is formed between the edge Of mGmbBI' 20 and the inner wall of the nozzle body 10, this passageway communicating with the'aforesaid slot. l9. 2 Member 20 issIightly longer. than the deep central por-.- tion of the nozzle and consequently, when the member 2.0 is in the position shown in Figs. 3 and 4, it blocks ,off flow to the central portion from the shallow end portions.
  • the extent of lip 23 is such that, when the member 2fl'is'in the position as shown in Figs. 3 and 4, this lip raises the forward lips I?
  • member 20 is caused to take the position shown in Figs. 1 and 2.
  • the nozzle is again raised from the floor, whereupon gravity causes the member to pivot as indicated by the arrow in Fig. 2.
  • a suction nozzle for cleaning a surface 45 a hollow body formed with a cleaning opening bounded by lips, and a member movable with relation to said body from a position outside said opening to a position reducing the effective crosssectional area of said opening, the dimensions 60 of said member being such with respect to those of said opening that when the member is in the second-mentioned position there is provided a small opening between said member and one of said lips, the portion of said lip adjacent to said small opening being cut away to provide a passage for flow of air over said sinface and into said small opening, said member having a passage forming an auxiliary air inlet to said hollow body whensaid member is in the second-mentioned position and spaced from said surface, the material bounding said auxiliary inlet on the side thereof which is adjacent to said surface when the member is in said second-mentioned position 5 extending downwardly to contact said surface when the nozzle is in operative position on the surface.
  • a suction nozzle for cleaning a surface, a hollow body formed with a cleaning opening bounded by lips, a member movable with relation to said body from a position outside said opening to a position within the opening, the dimensions of said member being such with respect to those of said opening that when the member is in the second-mentioned position there is provided a small opening between said member and one of said lips, the portion of said lip adjacent to said small opening being cut away to provide a.
  • said mem ber having a passage forming an auxiliary air inlet to said hollow body when said member is in the second-mentioned position and spaced from said surface, and a rim on said member 5 around said auxiliary inlet on the side thereof which is adjacent to said surface when the member is in said second-mentioned position, said rim extending downwardly to contact said surface when the nozzle is in operative position on the surface.
