  • Patent number: 5482246
    Abstract: An anchoring device having an auger disposed circumferentially around the device and a spiral-shaped member mounted to a distal end of the device to facilitate insertion of the device into sand or loose dirt. The auger preferably includes a radially outward edge which is upwardly curved to give the auger a generally scoop-shaped configuration. This scoop-shaped configuration is capable of entering the ground and retaining earthen materials and thereby provides a significant anchoring effect. The anchoring device is either attachable to the bottom end of a device to be anchored, such as an umbrella post, or is integrally formed therewith.

  • Patent number: 4073145
    Abstract: A seawall structure adapted to combat erosion of a shoreline by wave action comprises a perforate wall arranged along and substantially parallel to the shoreline and having openings therethrough facing seaward through which the water of incoming waves may pass. Each opening through the wall forms a tortuous passage for the water so that the energy of the water is dissipated gradually as it flows through the wall, thereby enabling sand entrained in the water to be deposited landward and seaward of the wall, as well as in the openings of the wall. The wall is composed of blocks arranged in horizontal rows and vertical courses, the upper edges of the blocks in the outermost rows projecting above the upper edges of the blocks of the next adjacent rows to provide an interlocking relationship between blocks of the outermost rows and the blocks of the next adjacent rows, as well as to provide for vertical deviations in the openings through the wall.
