Definitions

  • My invention relates toa suction nozzle for vacuum cleaners or the like, and more particu- Germany August 15, 1936 larly to a nozzle which is movable in two diiery ent planes to permit-it to follow the surface being cleaned.
  • An object of my invention is to provide an improved suction nozzle which readily assumes the desired position, depending upon the shape of the surface being cleaned.
  • Another object of my invention is to provide a nozzle with a ball and socket connection to a conduit, which permits the lnozzle to rotate in the plane of the working surface and permits tilting of the conduit with respect to the nozzle and working surface.
  • Another object of my invention is to provide an improved ball and socket connection for a suction nozzle of rugged construction, consisting of a minimum number of parts, which may be readily assembled together and manufactured at a. relatively low cost.
  • Figure 1 is a plane view of my improved nozzle located in position for cleaning a window
  • Figure l2 is a sectional view, on an enlarged scale, of the nozzle and connector
  • Figure 3 is a sectional view, taken on line 3-3 of Figure 2
  • Figure 4 is a bottom view of the nozzle
  • Figure 5 is a top View of the nozzle
  • Figure 6 is a perspective view'of a modified form of pivot.l
  • I0 indicates my improved nozzle connected by a connector II to a suction conduit or tubular handle I2.
  • Nozzle I0 is shown located in position on a window .it for cleaning surfaces having sharp corners,
  • the two balls Il act as' pivots for the connector I I, permitting the nozzle I2 to be inclined at a greater or lesser angle to the working surface as desired without permitting relatively loose universal movement of the handle.
  • a recess or track I8 is provided n the two parts I5 and I6 oi' nozzle Ill in a plane.
  • the connector II is provided with a passage I9, which communicates with an opening'23 in the nozzle I0 at one end, and with the hollow tubular conduit I2 at the other end. As may be better seen by.
  • the provision of. the balls Il for pivotally securing connector II to the nozzle and the track I8 cooperate to produce the desired movement of the handle I2 and rotary movement of the nozzle I0, without in anyl way obstructing the passage between the nozzle I0 and ⁇ conduit I2. Also, the assembly of the nozzle and connector simply requires that the connector be inserted in one of the two .l
  • part I6 is a To permit ready rotation of the nozzle I0 and at the same time to permit the tilting of the conduit or handle I2, connector II is provided with a balll ljoint adapted to t in a spherical cavity or socket provided in the'two parts I5 andiIG of nozzle I0.
  • the two parts I5 and I6 are secured to the ball Il of connector II by substantially flat surface of triangular shape. around the edges of which is secured an annular brush 2
  • a protective band 22 is secured around the edge of the nozzle I0 and is clamped in position between the two parts I5 and I8.
  • opening 23 of nozzle III is located substantially in the center of the nozzle, and communicates withthe ypassage I9 oi' connector II.
  • a cylindrical pin 2l as shown in Figure 6, may be used and connected to an arcuate segment 25, which is adapted to ride pin 2l may be arranged to ride directly in the track Il o! nozzle I 0 without the provision of the segment 2l.
  • an improved nozzle is provided with a connector which permits the nozzle to rotate, to permit it to travel around an irregular surface, and also permits the conduit connected to it to be inclined at any angle desired by the provision of a ball and socket joint with pivot means for limiting the movement of the joint in some respects, without at the same time interfering at all with the operation of the nozzle.
  • the connector which permits the nozzle to rotate, to permit it to travel around an irregular surface, and also permits the conduit connected to it to be inclined at any angle desired by the provision of a ball and socket joint with pivot means for limiting the movement of the joint in some respects, without at the same time interfering at all with the operation of the nozzle.
  • nozzle and' connector are provided' with a minif mum number of simple parts that may be readily a connector for connecting said nozzle to said conduit and having a ballon one end seated in the cavity in said nozzle, two pins carried at opposite sides of said ball, and arcuate segments connected .to said pins and adapted to ride in an annular track in said two part nozzle parallel to the face of the nozzle whereby the nozzle may rotate in a plane parallel to its face and the conduit may move in a. plane perpendicular thereto.
  • a vacuum cleaner including a nozzle adapted to engage a relatively flat working surface and a conduit, a ball and socket pipe joint connecting saidnozzle and conduit, meansproviding for limi-ted tilting and rotary movement between said nozzle and conduit comprising cooperating pivot and track means disposed respectively one on the ball and one on the socket with portions located in diametrically opposite positions relative to the ball and riding in said track providing for unobstructed passage through said pipe joint.
