  • Patent number: 6224953
    Abstract: An artificial palm tree has a trunk made from at least one tapered pole segment. Multiple trunk segments are butt connected with doweling screws threaded at both ends. A palm head in the form of a cylindrical solid is attached to an uppermost end of the uppermost segment of the trunk in the same manner as abutting segments of the trunk are attached to one another. A plurality of frond attachment holes are bored in the head. Each attachment hole is sized to accept a removable wood dowel pin. Each dowel pin, when inserted within its receiving hole, is angled to approximate the position of a frond on the trunk. Prior to assembly, each trunk segment and the palm head are individually wrapped with a layer of palm matting harvested from live palm trees. The matting layer is either stapled or adhesively bonded to the wrapped trunk segments and head. Wrapping of the palm head is performed with the dowel pins inserted within the frond attachment holes so that the dowel pins may serve to mark the location of the holes.

  • Patent number: 5221565
    Abstract: A novel mechanism and related processes for joining naturally grown and artificially produced parts to create aesthetically appealing, naturally appearing, large artificial plants, such as trees. A novel joint mechanism provides the appearance of naturally occurring outgrowth of branches and the like from proximally disposed trunks and stems. A method for bending and forming artificial foliage provides a more airy, naturally appearing leaf pattern around the crown of a plant.

  • Patent number: 5022202
    Abstract: The high strength post framed enclosure provides a subsurface mechanical room or work area that is dust free, waterproof and electrically insulated. The strong outer skin conforms to the structural frame when placed under pressure and creates a lightweight composite structural system to protect the enclosure.

  • Patent number: 4411547
    Abstract: A haunch connector for use in building trusses comprises two channels secured together at an angle and clamping means for clamping elements of the truss into the channels. The construction permits the assembly of large trusses without the need for pre-drilling old holes in the ends of the trusses, thus strengthening the points of connection of the structural elements and permitting limited adjustment of the angles of adjacent elements within desired limits.

  • Patent number: 4317316
    Abstract: The specification discloses a truss having first and second wall columns and first and second roof elements. Knee braces connect the wall columns intermediate their ends with the roof portions intermediate their ends. A center cord spans the roof sections, the latter comprising pairs of stacked wooden elements arranged vertically edge to edge bridging the point at which the knee braces join the roof elements and the point at which the center cord joins the roof elements. The construction minimizes costs and wastage of materials, and uses standard commercially available lumber while providing for adequate strength.
