Definitions

  • the invention provides, for the unidirectionally rotatable 15/411481 49 50 C, brush of a carpet sweeper, a clearer comb whose teeth are 15/142 38 spaced-apart parallel triangular plates having tips that project into the bristles of the brush.
  • An object of this invention is to obviate this difficulty and to provide a construction of clearer, as above discussed, which prevents adhesion of threads and bits of fluff to the bristles, which remains clean at all times, and maintains the entry to the dust collector always free, whilst preventing dirt or other matter from getting out of the dust collector back to the rotating brush upon backward and forward movement of the sweeper.
  • the present invention provides a clearer for clearing the unidirectionally rotatable brush of a carpet sweeper to keep it free of adherent matter and debris, which is a comb having teeth in the form of triangular plates spaced apart side-by-side in parallel planes, the tips of said teeth projecting into the bristles of the brush.
  • each tooth has a front edge which is inclined at an angle in the range from 60 to 70 relative to the horizontally disposed ones of said bristles or to the horizontal diametral plane of the brush and a rear edge which is substantially perpendic ular to the horizontally disposed bristles or to the horizontal diametral plane of the brush.
  • FIG. 1 is a fragmentary vertical longitudinal cross section showing a carpet sweeper incorporating a preferred embodiment of the clearer of the invention.
  • FIG. 2 is a fragmentary plan of the brush and clearer assembly with the top of the sweeper omitted.
  • a carpet sweeper 1 is fitted with running wheels 2 and a rotatable brush 3.
  • the brush 3 rotates unidirectionally only in the direction of the arrow in FIG. 1, so that dirt or other foreign matter picked up by radial bristles 4 of the brush are swept to the right towards the middle of the sweeper as the sweeper travels to the right so as to be received by a dust collector 5.
  • Teeth 7 of the clearer 6 are designed as thin triangular plates, as can be seen from FIG. 1,
  • each tooth 7 is so orientated that the rear edges 10 of the teeth are located'a substantial distance forward of the brush axis to locate the tips 8 thereof directed towards and preferably disposed substantially at the midpoints of the bristles 4 when the latter are projecting horizontally forward towards the dust collector 5 as shown in FIG. 1.
  • the front edge 1 l of each tooth 7 is inclined upward and forward from the forward portion of the brush and the angle 9 between the front edge of each tooth, the edge farther from the brush axis, and the bristles projecting horizontally forward advantageously is in the range from 60 to 70, formin an under bevel.
  • the rear edge 10 of each tooth 7 the edge 0 oser to the brush axis preferably extends substantially perpendicularly to the horizontally projecting bristles.
  • the clearer can be manufactured from any suitable material, but it has proved particularly successful to make it from a plastics material with the teeth integral with and projecting edgewise forward from the supporting back bar of the clearer, as shown in FlGS. l and 2.
  • the bristles 4 of the brush 3 need not necessarily be radially disposed as described, but the relationship of the comb teeth front and rear edges to the forwardly projecting horizontal brush bristles will have such relationship to the forward portion of the horizontal diametral plane of the brush.
  • a carpet sweeper comprising a rotatable brush, and a clearer comb for clearing adherent matter and debris from said brush including downwardly tapered triangular plate teeth spaced apart in parallel planes, having apexes projecting downwardly into bristles of said brush having a greater component of movement upward than rearward past said downwardly projecting teeth apexes, each of said comb teeth having an upright edge closer to the axis of rotation of said brush disposed substantially vertically and an upright edge farther from the axis of rotation of said brush inclined downwardly and toward the axis of rotation of said brush to form an under bevel inclined at an angle in the range of 60 to 70 relative to horizontal, at least the upper portion of the under bevel edge of each tooth being located above the path of movement of the brush bristles as the brush rotates, and means supporting said triangular plate comb teeth in cantilever fashion by their apexes at the upper ends of said substantially vertical edges, providing spaces between adjacent upper edge portions of said teeth unobstructed over at least the major portions of
