Definitions

  • the invention is an improvement on copending application Ser. No. 597,962, and now U.S. Pat. No. 3,457,575, filed Nov. 30, 1966 by Gunter Bienek, entitled Sweeper For Carpeted and Smooth Floors," and assigned to a common assignee.
  • a pair of rotatable brushes are provided, with the dust pans disposed either between or outside the brushes.
  • Each brush rotates unidirectionally to continuously sweep dust and debris into its respective dustpan, no matter whether the sweeper is being translated in a fore or aft direction over the floor, which may be either carpeted or smooth.
  • the sweeper is translated in one direction, one brush is driven while the other freely rotates.
  • the formerly driven brush freely rotates and the formerly freely rotating brush is driven.
  • the present invention is directed to the addition of combs for the brushes of the above-identified sweeper.
  • a comb is positioned adjacent each brush and normally hangs substantially free of the'brush while the sweeper is at rest.
  • inertial forces will cause one of the combs to move into engagement with its adjacent driven brush to comb the same, and will cause the other comb to remain substantially free of its freely rotating brush. Reversal of movement of the sweeper will cause the comb positions to reverse.
  • FIG. 1 is a perspective view of a floor sweeper constructed in accordance with the invention
  • FIG. 2 is a top plan view of the sweeper with portions of the cover removed;
  • FIG. 3 is a transverse section taken on line 3-3 of FIG. 2, when the sweeper is at rest;
  • FIG. 4 is a section taken on line 4-4 of FIG. 3 and showing the comb mounting and stop means
  • FIG. 5 is a section similar to FIG. 3, and showing the position of the combs when the sweeper is moving left;
  • FIG. 6 is a section similar to FIG. 3 and showing the position of the combs when the sweeper is moving right.
  • the invention is embodied in a carpet sweeper having a frame which includes sidewalls I and a cover 2, as well as strengthening crosspieces 3 and a transverse web 4.
  • a suitable bail 5 is attached to the frame, and has the usual handle, not shown.
  • a pair of spaced rotatable sweeper brushes 6 and 7 are mounted to the frame. Each brush is fixedly mounted on an axle 8, 9 mounted in suitable bores in sidewalls l.
  • Axle 8 is provided with a coupling means, such as wheel disposed between each outer brush end and the respective sidewall 1.
  • axle 9 is provided with a coupling wheel 11 disposed between each outer brush and the respective sidewall. Both pairs of wheels are freely rotatable on their respective axes. Wheels 10 and 11 are continuously engaged and driven by two pairs of sweeper drive wheels l2, 13 which support the sweeper on the surface for reciprocating translation thereover. Drive wheels l2, 13 are fixedly mounted on respective rotatable axles 14, 15 which are supported by and extend through crosspieces 3.
  • Frictional engagement means are provided between adjacent coupling and drive wheels. As shown in the drawings, the frictional engagement means comprises a rubberlike surface layer 16 on coupling wheels 10 and a similar layer 17 on drive wheels 12. If desired, the friction layer could be disposed on all drive wheels and/or on all coupling wheels without departing from the spirit of the invention.
  • Brushes 6 and 7 are adapted to sweep dust and debris from the surface of a floor 18 into suitable receptacles.
  • a pair of dust pans 19, 20 are disposed between the brushes and are pivotally mounted adjacent drive wheel axles I4, 15 respectively.
  • Pans I9 and 20 are provided with a closed floor, but are open at the top and along the side facing the respective brush.
  • An inclined lip 21 on the open side of each respective pan assists the adjacent brush in its sweeping action.
  • an inclined fluff trap 22 is secured to axles I4 and 15 to prevent debris from escaping the pans.
  • Brushes 6 and 7 are so constructed and controlled so that they continuously rotate in one direction only and thus sweep dirt and the like into their respective pans at all times, regardless of the direction or change of direction of reciprocal translation of the sweeper over a floor surface.
  • each brush is adapted to rotate freely in one direction so that contact of the brush with floor 18 during translation will cause the brush to sweep into its respective pan.
  • the direction of permissible free rotation for one brush is, however, opposite to the direction of free rotation for the other brush.
  • brush 6 will rotate freely in counterclockwise direction during leftward sweeper translation
  • brush 7 will rotate freely in a clockwise direction during rightward sweeper translation.
  • a coil spring 23 is circumferentially wrapped counterclockwise about each end portion of brush axle 8 and is held in place within the bore in sidewall l.
  • a second coil spring 24 is similarly wrapped counterclockwise about axle 8 inwardly from each spring 23, and is held in place within a bore in freely rotatable coupling wheel T0, with one spring end engaging the wheel.
  • Clockwisewrapped coil springs 25 and 26 are similarly mounted about axle 9.
  • inertia-operated means which cooperate with the continuously unidirectionally rotating brushes to clean threads and other debris from the brushes.
  • an elongated comb 27 is disposed slightly inwardly of and on the dust pan side of brush 6.
  • Comb 27 is parallel to brush 6 and disposed adjacent the upper inner quarter of the brush, and is provided with suitable teeth 28 along its lower edge.
  • comb 27 is bent along its upper edge to form a lip 29, and tongues 30 extend from the ends of the bend into opposed openings 31 in crosspieces 3 to pivotally support the comb thereby.
  • a second comb 32 similar to comb 27 is disposed slightly inwardly of and on the dustpan side of brush 7.
  • Comb 32 has the same elements as comb 27 and is parallel thereto.
  • stop means comprising an opening or slot 33 in each crosspiece 3 adjacent each comb end.
  • An ear 34 extends from each comb end and into each slot. Ears 34 extend generally parallel to but spaced downwardly from tongues 30.
  • slot 33 The opposed edges of slot 33 are engaged by cars 34 to limit the comb movement.
  • One limit of comb position is such that teeth 28 are positioned just free of the tips of the bristles of the brush.
  • the other limit is such that teeth 28 are positioned within the bristles.
  • the inventive concept may also be usable in a sweeper having only a single unidirectional, alternately driven and freely rotating brush.
  • said brush being mounted to contact and freely rotate on the floor in a direction to deliver dust to the dust-receiving area upon translation of the sweeper in one direction
  • a floor sweeper comprising, in combination:
  • each said brush being mounted to contact and freely rotate on the floor in a direction to deliver dust to the dust-receiving area upon translation of the sweeper in one direction, c. means to positively drive each said brush in the same direction as its aforementioned free rotation upon translation of the sweeper in the opposite direction,
  • the sweeper of claim 4 which includes stop means to limit the extent of pivotal movement of each comb.
  • a floor sweeper comprising, in combination:
  • each said brush being mounted to contact and freely rotate on the floor in a direction to deliver dust to the dust-receiving area upon translation of the sweeper in one direction
  • each comb b. and an ear extending from each comb into said opening for contacting said edges.
