Foot for upright cylindrical vessel - has top curved edge welded to top cylindrical section of vessel bottom and bottom edge welded to footplate

摘要

The foot (4) is for a metal vessel with domed or flat bottom, and tapers from the top to a bottom edge resting on a footplate. Its top edge (5) curves to the same radius (6) as that (7) of the vessel (2), and is welded to a top cylindrical portion (9) of the vessel bottom (3) and which forms an extension of the vessel casing (8). The curved sidewalls (10, 11) of the foot end at a bottom edge (12) on a part-circle inside the vertical projection of the top edge (5) and tangential to it. ADVANTAGE - Avoids transmission of reaction forces due to the full and empty weights of the vessel into its bottom.
