Definitions

  • An object of the invention is to provide a new and improved surface-cleaning tool. Another object is to provide a cleaning tool having a resilient body for attaching thereto a brush and a conduit. Another object is to provide a swivel joint between a conduit and the cleaning tool. A further object is to provide a cleaning tool having a resilient body which acts to secure thereto a swivel joint.
  • Figure 1 is a top plan View partly in section of the cleaning-tool
  • Figure 2 is a front view partly in section
  • Figure 3 is a section along the line 3-3 of Figure 2;
  • Figure 4 is a section along the line 4-4 of Figure 2.
  • Figure 5 is a section along the line 5-5 of Figure 2.
  • the cleaning tool herein disclosed is of the type adapted to be connected at one end of a dusting tool hose which is secured to a suction cleaner.
  • the nozzle includes an upper body portion I formed of a molded resilient rubber or plastic to which is attached a lower body portion 1 I forming a brush assembly.
  • the resilient por tion It comprises an integrall formed socket I2 having an arcuate side wall I3 and a front wall I4, both of which merge with an elongated top wall I having a depending peripheral side wall I6 terminating in an inwardly projecting shoulder I! which cooperates with the side wall I6 and the adjacent edge portion I8 of top wall I5 to form a channel-shaped seat or recess I9 extending along the side wall I6.
  • the brush assembly II includes an elongated brush back or frame having a peripheral shoulder 2
  • a swivel joint is provided between the socket I2 and an angular conduit 4
  • the swivel joint comprises a pair of semi-cylindrical metal members 42 and 43,
  • each of which has its opposite ends 44 in abutting engagement to form a cylindrical member having an outside diameter slightly larger than the in side diameter of the socket I2 so that the latter frictionally secures the members 42 and 43 against rotation.
  • Longitudinal movement between the socket I2 and the members 42 and 43 is prevented by providing flanges 45 and 46 on the opposite arcuate ends of the members, the flanges 45 abutting a shoulder 41 on the socket I2 and the flanges 46 abutting the extreme end 48 of the socket I2.
  • Rotatably mounted within the members 42 and 43 is a reduced portion 49 of the conduit 4
  • the semicylindrical members 42 and 43 are arranged about the reduced conduit portion 49 between the shoulders 50 and 5
  • the operator moves the nozzle over the covering to be cleaned with the bristles 26 and 21 in contact with the covering to dislodge the dirt into the air stream, and the dirt-laden air stream passes through the elongated brush inlet 28, restricted nozzle inlet 24, air passageway 23 and the outlet 25 into the chamber 20, and then passes through the conduit 4
  • a coupling comprising a rigidtub-ular mem ber having spaced annular flanges which define 2.
  • a nozzle body having a tubuar portion formed of resilient material; "a rigid conduit extending from said nozzle body, saidrigid conduit maving space'd flanges defiiiing a .recess .therebetwee'n, a pluralityof: measure members each having an arcuate sunfac'e and spaceduarcuateflang es iso definean a ienate recess therebetween, .s'aid arcuate members nestedin said conduit recess- Withsaiid rigid" arm-rate:- faces and arcuate flanges rotatably engage'd respec-tively with said recess-and conduit flanges, and said resilient t'ubular portion of said nozzle expanded into -saii
