Definitions

  • Fig. 2 is a longitudinal sectional View taken on the line II-II of Fig. 3 showing a preferred form l5 of the invention
  • Fig. 3 is a side view of a preferred form of radiator tool.
  • Fig. 4 is a section taken on the line IV-IV of Fig. 3.
  • My new radiator tool is applicable to any kind of vacuum cleaner but I have shown it attached to the hose II of a vacuum cleaner of the kind having a cleaner unit Ill adapted to be -pulled on the floor by means of the hose.
  • a flattened tubular member I6 of known construction which may have an oblique opening as shown in Fig. 3 at 30.
  • Member I6 is preferably made of metal so that it will not distort.
  • a brush tool 30 or radiator tool or nozzle designated generally by numeral I2.
  • Tool I2 includes attened side members I3 vwhich have projections I4 on the sides which are crimped together to form the shank portion fitted over the tool I6.
  • the sides may be 35 separated at 3
  • the side members I3 are formed with rounded parts I8 which are generally circular and the circumferential periphery 40 of which extend for the greater part of a complete circle. The diameter of the circle is considerably wider than the width of the shank portion.
  • the outer edges of the parts I8 are bent or flanged obliquely outwardly at I I.
  • the outside edges of the flanges I1 are preferably in the same plane as the flat portions of the side members I3.
  • pieces I9 which are arcuate in shape and which are tightly se- 50 cured to the parts I8 in any desired manner as by tongues 20 pressed out of the pieces I9 and extending through slots in the side members I3.
  • 'I'he pieces I9 are flanged at 2l.
  • likewise extend obliquely outwardly from the gen- 55 eral path of flow formed within the tool, which is longitudinally thereof in the embodiment disclosed.
  • knobs or projections 25 may be'provided in the pieces I9 adapted to press against the complementary piece and prey vent reduction of the nozzle opening beyond a given amount.
  • 'I'he bristles may be mounted on twisted wire 24 which is clamped between the flanges I'l and 2l by pressing these anges together.
  • 'I'he wire may be passed through slots in the members I3 and I9 and bent over to hold 20 the same in place or other fastening means may be employed.
  • the parts I1 and 2l form oblique grooves for the bristle rows.
  • auxiliary openings 26 are provided in the side parts I8 by aperturing the side members and also the pieces I9 should they overlap at the places where it is desired to have the auxiliary openings.
