Definitions

  • the present invention relates to ground sweepers and has particular reference to ground sweepers of the kind comprising a wheeled frame for translational movement over surface to be swept, said frame carrying a dust receptical and a brush assembly adapted to be driven by at least one of said wheels on which the frame rides during translational movement.
  • a side brush assembly on one or both of the front sides of the machine; these side brushes have comprised an inverted cup shaped brush member having a generally peripheral bristle assembly, which member is arranged for rotation on a substantially vertical spindle, the brush member being driven by means of a belt from an appropriate drive wheel for the main brush assembly for the sweeper.
  • Forward or rearward movement of the sweeper thus results in rotational drive being transmitted from one of the wheels upon which the device moves to the cup shaped member itself, so that translational movement of the sweeper results in the driving of the brush in such a way as to sweep dust at the edges of an area to be swept into the path of the main sweeping brush.
  • a side brush assembly for a sweeper of the kind described which assembly comprises a brush member journalled for rotation about an axis at a substantial transverse angle to a surface to be swept, a bristle assembly disposed about the periphery of said member and arranged for sweeping contact with said surface on rotation of said member,
  • the side brush assembly is secured to the main frame of this sweeper by means of a support arm which is movable about a substantially horizontal axis. With the brush in the brushing position, the support arm is locked to maintain the roller means in rolling contact with the surface to be swept.
  • the brush member is generally cup shaped and has a peripheral brush assembly disposed thereabout. The mounting of the brush member is preferably adjustable to allow adjustment to take up of wear of the bristle assembly.
  • the roller means may be biased to contact the surface to be swept and the drive means may comprise an intermediate drive plate in contact with the roller means so that on rotation of the roller the drive means is rotated by virtue of friction drive between the roller periphery and an annular portion of the drive plate.
  • a locking pin may be provided between the drive plate and the brush member so that drive to the plate is transmitted to the brush member per se.
  • the brush member may be journalled for rotation on a substantially vertical rod having at its lower end, an axle portion substantially perpendicular to the axis of said rod, said axle portion carrying the roller means.
  • the annular disposition of the axle portion may be selected with respect to the forward-rearward axis of the sweeper so that the appropriate sweeping action is provided depending on which side of the sweeper brush assembly is mounted.
  • Figure 1 illustrates the main chassis and brush assemblage of a sweeper in accordance with the present invention.
  • This sweeper appears in our copending British Patent Appl No. 8013493 filed on 24th April 1980.
  • a front cross bar extending perpendicular to the upper extremity of support 19 which constitutes a cross piece upon which a movable arm is provided.
  • This movable arm is capable of rotational movement in a substantially vertical plane about an axis carried by the support referred to above.
  • the extremity of this arm has a substantially vertical bore adapted to receive an erect rod 30 (see Figure 2).
  • Rod 30 is threaded at its upper end at 31 which threaded portion is adapted to receive a sleeve portion 32 and a threaded adjustment nut 33 having a side arm 34.
  • the rod 30 is further provided with an upper portion 35 of reduced diameter, said portion 35 also being threaded and being adapted to receive a threaded locking member 36 for the purpose of securing rod 30 to the forwardly extended arm referred to above.
  • the rod 30 carries at its lower end an axle portion 37 extending substantially at right angles to the vertical axis of erect rod 30.
  • the axle portion 37 has towards its outer extremity and outer and inner annular grooves 38 and 38'. Grooves 38 and 38' are spaced one from the other, the axle portion disposed between grooves 38 and 38' carrying a wheel 39 which is retained on axle portion 37 by means of circlips located in said grooves.
  • Wheel 39 is freely rotatable upon said axle portion, and has a rubber periphery which in the operative wheel position of the arm carrying erect rod 30 and(39, is adapted to abut and be in rolling contact with the surface adapted to be swept.
  • the erect rod carries upper and lower spaced bushes 40, 41 each of bushes 40 and 41 is formed of a plastics material to act as a bearing for erect rod 30.
  • Each bush 40, 41 comprises a cylindrical portion 42 and a radially extending flange 43.
  • the upper bush is disposed with its radial flange 43 disposed uppermost and the lower bush with its radial disposed lowermost, the arrangement being such that the flange 43 of lower bush 41 is arranged to abut a stop.
  • the upper bush is juxtaposed the inverted cup shaped member 50 having a generally upper disc portion 51 and a depending side wall portion 52 which terminates towards its lower end in a flared portion 53 which later carries a peripheral bristle assembly 54 the lower extremity 55 of which is disposed in brushing contact with a surface upon which the device moves.
  • the disc portion 51 is provided with a central bore 56 and is adapted to be disposed over the cylindrical outer surface of the cylindrical portion 42 of upper bush 40.
  • the disc portion 51 is further provided with an intermediate drilling disposed outwardly of the radial flange 43 of upper bush 40.
  • the bush assembly 40 and its associated brush assembly 50 is biased upwardly against the lower extremity of sleeve 32 by means of a compression spring 57, the arrangement being such that the relative position of disc portion 51 from the surface on which the device moves may be adjusted by means of adjustment nut 33.
  • the lower bush 41 is associates with friction drive plate 60 comprising a central disc portion 61 having a central bore 62 adapted to accommodate the cylindrical portion of bush 41 said disc being retained in position thereon by means of the bias of spring 57.
  • the outer extremity of disc 61 is formed as a frustoconical portion 63 the walls of which extend upwardly and outwardly from disc 61 and terminate in an annular portion 64 which is adapted to be in contact with the upper surface 65 of wheel 39 and is biased into abutment therewith by means of compression spring 57.
  • a drive peg 66 extends upwardly of annular portion 64 at the junction thereof with frustoconical portion 63 and extends upwardly to engage with the intermediate drilling in disc portion 51.
  • the advantage of the device is that the drive for the brush assembly is independent of the drive of the sweeper per se and that when not required, the device can be hinged upwardly and with the wheel 39 out of contact with the floor and the sweeper used in the ordinary way.
