  • Storage vessel and method of assembly
    Patent number: 4616465
    Abstract: A storage tank, such as a water tower is disclosed, made by bolting rows of glass-coated steel plates together. The plates overlap each other side to side and above and below. The contact with plates at the diagonal corners is not an overlapping contact but an abutment contact, and the lines of abutment contact are staggered row to row. This arrangement leads to a very efficient use of material, and to an inherently leak proof structure when the plates are arranged to form a double skin in the lower regions of the tower.

  • Plastic insert for storage vessel
    Patent number: 4591067
    Abstract: Bolted plate water towers have a potential for leakage at abutment joints between the plates, if the gap between the abutting edges is large, and if the water pressure is high enough to extrude the jointing compound out of the gap. But the gap must be wide enough to ensure the edges do not touch. In the invention, a compressible plastic insert (8) is placed between the abutting edges (5,6) to keep the gap from being so variable. Hence, water towers can be built to greater height.
