  • Patent number: 4570812
    Abstract: A community refuse receptacle including a flexible wall container secured at its open end in depending relation to the bottom surface of a cover overlying a well in the surface of the earth. The cover is provided with a central opening opened and closed by a hingedly connected lid. A pair of horizontally disposed tubular members are connected with the cover at opposing edges of the lid. The tubes receive lifting arms of a commercial waste disposal unit for lifting and inverting the container in an emptying action wherein the lid falls by gravity to an open position. Wall stabilizing, members depending from the lid, prevent collapse of the container when inverted.

  • Patent number: 4489810
    Abstract: In a concealed garbage can container an upwardly open housing, having a hinged lid for containing one or more refuse containers, is recessed into the surface of the earth so that only its lid is exposed. A refuse can supporting platform within the housing is moved vertically by a winch driven reversible motor to raise and lower the platform. Pivoting links, extending between the platform and lid, simultaneously opens and closes the lid with vertical movement of the platform. Rollers, mounted on the platform engaging housing supported standards, maintain the platform horizontal during its vertical movement.

  • Patent number: 4238890
    Abstract: Apparatus for field drying harvested crops, particularly peanuts, in the form of an open-topped container having sides, ends and a bottom of wire mesh fine enough to retain the crops. Tubular wire mesh conduits extend inwardly from opposite side walls and terminate inside the container. Pivoted legs support the container above the ground, oriented in a direction to direct natural currents of ambient air into the conduits and through the contained crops. Selectively usable shades and shutters permit shading from direct sunlight and exclusion of air flow or inclement weather.
