Definitions

  • My invention relates to hose or other flexible conduit and more particularly to a hose of substantial diameter in which is incorporated an electric cord.
  • a stretchable electric conductor such as that disclosed in Patent No. 2,013,- 211 issued September 3, 1935 to Karl Herkenberg, the conductor being stretched before being secured to the hose sufiiciently so that when the hose is bent with the con ductor on the inside of the bend the conductor may contract so as to retain its original straight form, except of course for the fact that it curves with the hose. If the hose is bent with the conductor on the outside of the bend it can of course stretch further, thus permitting a free bending of the hose without subjecting the conductor to any damaging stress.
  • One advantageous application of my invention is to tank type vacuum cleaners when it is desired to transmit electricity from the main unit to a motor located in a nozzle which is connected to the unit by means of a suction hose, although it is to be understood that my invention may be used with various other types of hose.
  • FIG. 1 is a side view, partially broken away, of a vac uum cleaner hose embodying my invention
  • FIG. 2 is a cross-sectional view on an enlarged scale of a section of the hose illustrated in FIG. 1 and showing a reverse bend in the hose;
  • FIG. 3 is a cross-sectional view of a slightly modified form of hose and is taken on the line 33 of FIG. 4;
  • FIG. 4 is a cross-sectional View taken on the line 4-4 of FIG. 3;
  • FIG. 5 is a cross-sectional view similar to FIG. 2, but showing my invention embodied in a different type of suction hose;
  • FIG. 6 is a view on a smaller scale and partially in cross-section of the hose illustrated in FIG. 5, but showing coupling members at the ends of the hose, the crosssectional portion being taken on the line 66 of FIG. 7;
  • FIG. 7 is a cross-sectional View taken on the line 7-7 of FIG. 6;
  • FIG. 8 is a top view of a portion of the hose shown in FIGS. 6 and 7;
  • FIG. 9 is a cross-sectional view similar to FIGS. 2 and 5, but showing my invention embodied in a third form of hose.
  • reference character 10 designates generally a flexible hose which is provided at one end with a push connector 12 for removably connecting it to a vacuum cleaner, and at the other end with a rigid tubular member 14 for connecting it to a suction cleaning tool.
  • the construction of the flexible hose 10 is shown more particularly in FIG. 2. It includes a tubular member 16 made of fabric impregnated with rubber or other suitable material to make it airtight. The fabric is preferably cut on the bias so that it is somewhat elastic in the lengthwise direction of the hose. Within the tubular member 16 is a supporting spiral wire 18 made of steel or othermaterial of suitable strength. The turns of the spiral 18 are preferably secured to the inner surface of the tubular member 16, as by vulcanizing during the construction of the hose. A cord or string of jute 20 or other suitable material is spirally wound around the outside of the tubular member 16, the turns of the string 20 being in between the turns of the spiral 18, as is clearly shown in FIG. 2.
  • a piece of stretchable two conductor cord 22 Prior to winding the string 20 around the tubular member 16 a piece of stretchable two conductor cord 22 is laid along side of the hollow body and extends in a straight line substantially parallel to the center line of the hollow body.
  • This stretchable cord may be of the type disclosed in the aforesaid Patent No. 2,013,211. Conductor cords of this type may be stretched up to 200% or more of their original length.
  • the string 20 thereupon serves to secure the conductor cord 22 to the tubular body 16 at spaced points along the length of the cord, namely at each point where the cord is held between the tubular 'body 16 and a turn of the string 20.
  • the tubular body with the conductor cord attached is provided with a braided cover 24 by means of a well known braiding machine.
  • the ends of the cord adjacent to the opposite ends of the hose are not secured in place by the string 26, but are covered by the braiding 24. However, these ends may be brought out through the braiding, -as is shown in FIG. 1, by inserting a hook shaped instrument between the strands of the braiding, catching the free end of the conductor cord and pulling it out.
  • a male plug 26 may be secured to one end of the cord, any desired length of free cord 2.2a being provided.
  • the other end 22b of the conductor cord may be secured to a receptacle 28 which is fixed to the end of the hose by means of the clamp 30'.
  • the push connector When in use, the push connector is engaged with a suitable inlet opening in the vacuum cleaner unit and the plug 26 is inserted in an electrical outlet on the unit, the free portion 22a permitting a certain amount of swiveling of the push connector 12 in the inlet opening.
  • a suitable cord from the nozzle is provided with a male plug which is inserted in the receptacle 28, thus completing the circuit from the unit to the nozzle.
  • the distance A between successive turns of the spiral 18 is approximately 7 of an inch.
  • the distance B between adjacent turns of the supporting spiral 18 at the inside of the bent portion of the hose is only about of an inch while the distance C between adjacent turns of the spiral 18 at the outside of the bend is approximately 4, of an inch. This means that if the conductor cord 22 is on the inside of the bend it must contract from %6 of an inch to ,4,, or approximately 33%.
  • the tubular body of the hose is designated by reference character 32 and is a tube of flexible plastic material. This tube is supported against collapse by the stiff spiral wire 18. Disposed between adjacent turns of the spiral and the inner surface of the tubular member 32 is the stretchable cord 22. As was the case in the previous embodiments, the cord 22 is elongated prior to being secured between the turns of the spiral and the tubular body by an amount sufiicient so that when the hose is bent with the cord on the inside of the bend it may contract and thus remain substantially parallel to the center line of the hose.
  • the plastic tubular member 32 constitutes the airtight portion of the hose, it is not practical to bring the cord 22 through it to the outside thereof adjacent to the ends of the hose, as this would permit leakage of air.
  • the cord is continued to the ends of the tubular body 32, the ends being secured within the push connector 12 and the rigid tubular member 14, respectively, as was the case in FIG. 1.
  • the cord after it emerges from the tubular member 32 is bent back on itself and extends along the outer surface of the tubular member to a point beyond the end of the push connector 12.
  • Ia semi-cylindrical member 34- of rubber or plastic is placed over the hose at this end and has a relatively thin portion 35 extending between the hose and the inner surface of the push connector.
  • the thin portion is formed with a groove 36 connecting with a channel 37 in the thicker part of member 34 within which extends the cord 22.
  • the cord is preferably provided with a free section 22a to the end of which is connected the plug 26.
  • the same construction may be employed at the opposite end of the hose, with the exception that the free section 22b of the cord is connected to a receptacle 38.
  • the hose comprises an inner tubular member 40 of airtight flexible plastic material and an outer body 42 of similar material between which is disposed a reinforcing fabric 44.
  • the stretchable cord 22 is disposed between the fabric 44 and the inner tubular member 40, it having been elongated prior to being secured therein, as previously described.
  • the cord may be brought out through openings formed in the outer tubular body 42. adjacent to the ends of the hose, similar to the manner shown in FIG. 2, inasmuch as the inner body 40 is airtight and would prevent leakage.
  • the cord may be continued to the ends of the hose and brought out through semi-circular members as is illustrated in the previous embodiment.
  • stretchable cord 22 has been referred to as having two conductors, it is to be understood that it may have any desired member from one up, depending upon electrical considerations. Also, even though my invention has been described in connection with various forms of suction hose, it is equally applicable to flexible conduits of other types.
  • a hollow tubular body made of flexible material, a stretchable elastic electric cord extending substantially parallel to the center line of said body, and means for securing said cord to said body at closely spaced points, said cord being in sufficiently elongated condition when secured to said body so that when said hose is bent with said cord on the inside of the bend the cord contracts and remains substantially parallel to said center line.
