Definitions

  • the present invention relates to work wheels and more particularly to a flap wheel having increased density at its radially outer end.
  • FIG. 1 is a side elevational view of a flap wheel embodying features of the present invention
  • FIG. 2 is an enlarged sectional view of the wheel of FIG. 1 taken generally along the lines 2-2;
  • FIGS. 3 and 4 are enlarged sectional views of FIG. 2 taken generally along the lines 3-3 and 4-4, respectively;
  • FIG. 5 is a view similar to FIG. 2 of a modified form of the invention.
  • FIG. 6 is an enlarged view of FIG. 5 taken generally along the lines 6-6;
  • FIG. 7 is an enlarged sectional view of FIG. 5 taken generally along the lines 7-7.
  • a flap wheel 10 has a hub assembly l2 and a plurality of finger assemblies 14 secured thereto at their radially inner ends.
  • a finger assembly 14 includes a long finger 16 which is notched at its radially inner end 18 to matably fit within grooves in the radially outer end 20 of the hub assembly 12 whereby the finger assembly 14 will be held to hub assembly 12.
  • Each finger assembly 14 includes a short finger 22 which is secured at its radially inner end 24 to the long finger 16.
  • the finger I6 (and finger 22) can be made of sisal 24 wrapped in cloth 26 with the short finger 22 being stitched at inner end to finger 16.
  • FIGS. 5-7 in which components similar to like components in the embodiment of FIGS. l4 have been given the same numeral designation with the addition of the letter postscript a.
  • the flap wheel 10a has a plurality of finger assemblies 14a which are secured at their radially inner ends to hub assembly 12a.
  • Each finger assembly 14a includes a long buffing finger 16a (identical to finger 16 of FIGS. l4) which has a plurality of long abrading fingers 17 secured thereto as by staples at 19; fingers 17 are also individually secured to hub assembl 12a.
  • a plurality of short abrading fingers 21 and a plurality of short buffing fingers 22a are secured to long fingers 160 by stitching 23 and staples 25 at points removed from the hub assembly 12a.
  • the result is a fiap wheel having a dense compact structure at its radially outer end which provides for improved performance.
  • the abrading fingers l7 and 21 can be abrasive coated paper on cloth. Note that the smooth (nonabrasive) surface on one of the abrading fingers is provided to engage each buffing finger adjacent a group of abrading fingers to prevent premature wear.
  • the fingers at the hubs (I2 and are compactly assembled with-adjacent fingers engaging each other so that a wheel of maximum density can be constructed.
  • a flap wheel comprising a hub, a plurality of finger assemblies secured to said hub and extending radially outwardly therefrom, said finger assemblies comprising at least one long finger member and at least one shorter finger member secured to said long finger member at a point radially spaced from said hub and extending substantially over its length coextensively with the associated one of said long finger members, each said long finger member having its radially inner end secured to said hub, said plurality of finger assemblies having a number of said long finger members to define a compact, dense structure circumferentially at the point of securement to said hub whereby with the addition of said shorter finger members to said long finger members a dense flap wheel structure as provided from its radially inner to its radially outer end.
