  • a suitable closure means such as a screw cap 33.
  • the bearing is thus protected from dust on one side by the closed nd of the housing.
  • On the opposite side itis protected by a cup-shaped packing washer 34 which surrounds the stud and seats adjacent the outer frace within the housing.
  • the 'washer carries a ring packing 35 of suitable material and a retaining washer 36 for the packing. The packing contacts with the stud and packs it against dust and other foreign matter which may tend to enter the bearing.
  • the brush stud 27 isconnected with the brush by a flanged or grooved head 37 which is integral with the stud and which is pressed onto the end of the brush tube.
  • the brush, grooved head, stud and inner race are thus connected and are rotatable together abouta common axis, while the housing, outer race and packing means remain stationary.
  • the housing is enlarged at it's'outer end to receive the grooved head fully within it and is of such internal diameter about the head-that only a close running clearance space i38-38 is provided between it and the head.
  • This space, together with an annular chamber 39 formed by the groove in the head provide a labyrinth packing between the dust-laden air within the nozzle and the inner packing means 34 and35.
  • the head-for the brush tube is also protected from thread winding by the housing which extends over it, that is overhangs the flange 40.
  • the above-described bearing structure may ,be considered to comprise a brush assembly which includes the brush or brush tube 19 with the heads mounted thereon, and the bearing assembly which includes the housing 2Q, bearing 23, and packing means,-together with screw 28 and washer 31.

  • the easy removal of the brush assembly from the bearing also facilitates occasional cleaning of the bearing and brush.
  • the construction has the advantage that the support for the bearing maybe located directly about the bearing, tlius eliminating vibration and wear ordinarily occasioned'by an overhung construction in which the bearing is supported hand this 24th day axially at a distance from the bearing sur-- the shouldered end of the stud is seated, means carried by the stud for engaging the inner race to hold the stud in said seated position,
