  • Patent number: 6776108
    Abstract: A planter apparatus includes a seed meter including a housing assembly with a cover releasably connected to a shell. The housing assembly includes at least one opening formed therein adjacent a seed discharge area to promote the release of seeds from a disc rotatably attached to the housing assembly. The disc divides an interior of the housing assembly to include a vacuum chamber and a seed chamber. The disc including a plurality of openings formed adjacent a periphery of the disc. The planter apparatus may also include a singulator assembly having rotatably spools, a rotatable chute door, a disc having clusters of openings for simultaneous release, and a one-piece baffle.
    Type: Grant

  • Patent number: 6514303
    Abstract: A rotary screen assembly rotatable about a rotational axis for filtering air entering an air inlet of a work machine, the screen assembly having an axially facing screen surface including an outer circumferential edge disposed around the rotational axis in radially spaced relation thereto, an elongate brush having bristles disposed along a longitudinal extent thereof in contact with the axially facing screen surface for brushing collected material and contaminants therefrom, the longitudinal extent or axis of the brush forming a chord of the outer circumferential edge spaced a distance from the rotational axis or being skewed relative to the rotational axis such that when the screen is rotated about the rotational axis in a predetermined direction a force is imparted to the collected material and contaminants by the bristles of the brush sufficient to move the collected material and contaminants radially outwardly past the circumferential edge.
