  • Patent number: 7967595
    Abstract: An apparatus and process for shaping multiple expended thermoplastic containers, specifically plastic bottles into rock shapes by placing the expended plastic bottles into a partitioned tray which is placed onto the top surface of a lift table secured to a jack mounted on a four-wheel dolly and heating the plastic bottles to a malleable state. The lift table is then rolled into an open face shaping chamber that has angle irons secured on the interior sides near the top of the chamber to support and allow a removable tray to which real rocks of different shapes and sizes have been secured to be slid into the chamber with the rocks pointing downward from the tray into the chamber. The lift table with the heated malleable bottles is jacked upward toward and into the real rocks until the bottles take the shapes of the real rocks. Then the table is lowered and wheeled out of the shaping chamber.

  • Patent number: 7866019
    Abstract: A method for converting expended plastic water bottles and other plastic beverage bottles into artificial landscape rocks and edging blocks by cutting a flap in an empty plastic bottle, filling the bottle with empty, crushed food cans, or compacted, expended plastic bottles, sealing the flap with wire lath and screws, wrapping the bottle with mason lath or chicken wire, or coating the bottle with a bonding agent, applying a stucco coating to the bottle, brushing the wet stucco, and coloring the stucco with a pigmenting agent.

  • Patent number: 7810708
    Abstract: A combination mailbox housing, pedestal and planter is constructed of recycled materials to be all in one unit. The pedestal is constructed from four expended five-gallon buckets, which are screwed together and covered with wire lath and stucco, and artificial plastic rocks which rocks have in turn been constructed from expended plastic bottles. The mailbox housing is constructed from used cedar fence boards in a board and batten style to enclose a standard metal or plastic mailbox. When the mailbox housing and pedestal is assembled into one unit and installed, soil is put into the planter sections of the pedestal wherein plants and/or flowers can be planted.

  • Patent number: 7736703
    Abstract: An artificial hollow core boulder and method of fabrication. A plastic trash bag is loosely filled with newspaper, tied shut, and wrapped with a layer of chicken wire. The chicken wire wrapped bag is hand pressed into a boulder like shape and a hole is cut into the chicken wire at the bottom of the wrapped bag. Wet stucco mix is troweled over the chicken wire and the wire is lightly pulled away from the plastic. A second layer of stucco mix is troweled over the dried first layer of stucco. A hole is cut in the plastic bag through the hole in the chicken wire and the newspapers are removed. The hollow core artificial boulder is filled through the hole with expended, crushed, cans and plastic bottles. The hole is sealed with chicken wire and stucco. The completed boulder is sealed with penetrating acid stain or latex stain.

  • Patent number: 7600991
    Abstract: An apparatus for converting expended thermoplastic material, specifically empty plastic bottles, into artificial rocks, by placing the empty thermoplastic bottle in the apparatus between two sliding carriages, on each of which a rock has been mounted; and each carriage attached to a hydraulic jack, which, when the handle is pumped, moves the carriage toward the bottle which has been heated to malleability by heat lamps mounted above and sideways to the bottle, and the said heated, flexible bottle is squeezed between the two rocks mounted on the carriages, and then the bottle is rotated and the process repeated to give the bottle a rock shape. The rock shape may be further altered using a portable heat gun.

  • Publication number: 20090022889
    Abstract: A method of making a bonding agent to bond stucco to smooth plastic articles, specifically plastic rocks, by coating the plastic article with a water-based coal tar or asphalt emulsion, putting dry sand over the wet emulsion by hand sprinkling or spraying the sand onto the coated surface of the article, or rolling the article in the sand, allowing the sand coated article to dry thoroughly, applying a wet stucco over the dry, sand coated layer, and allowing the stucco coated article to dry.

  • Patent number: 7115178
    Abstract: A method and apparatus for converting expended thermo-plastic material, specifically empty plastic bottles, into artificial rocks, by placing the empty thermoplastic bottle in the apparatus between two sliding carriages, on each of which a rock has been mounted; and each carriage attatched to a hydraulic jack, which, when the handle is pumped, moves the carriage toward the bottle which has been heated to malleability by heat lamps mounted above and sideways to the bottle, and the said heated, flexible bottle is squeezed between the two rocks mounted on the carriages, and then the bottle is rotated and the process repeated to give the bottle a rock shape. The rock shape may be further altered using a portable heat gun.
