Stabilized mounting for boflike vessels

Claim 1

In a furnace vessel for processing molten metal having an outer metal shell wall and an inner refractory lining and adapted to be positioned on a pair of supports, an improved combination defined when the vessel is in a vertical upright position as follows: a trunnion ring extending in a spaced position about a substantially central area of the outer periphery of the metal shell wall, a pair of trunnions projecting from diagonallyopposite positions on a common horizontal axis from said ring for mounting the vessel on the pair of supports, a group of diagonally-opposed upper pairs of mounting assemblies in a spaced-angular relation with respect to each other about said ring, said group being connected to the shell wall on a common transverse horizontal plane adjacent an upper side of the trunnion ring, each said upper mounting assembly having an angleshaped bracket and a pair of spaced-apart cooperating keepers, each said bracket having a vertical mounting plate secured on the shell wall and having a substantially planar horizontal foot plate secured in an angular relation to said mounting plate to form a unitary construction, each keeper of said cooperating pair having a mounting portion rigidly-secured on an upper side of the trunnion ring to extend therealong and having an upwardly-offset clamping portion adapted to extend over one end portion of said foot plate of an associated bracket, a pair of angle-shaped wedge elements for each of said keepers, each of said wedge elements having an inner tapered face therealong and an opposed outer substantially planar face therealong, said offset clamping portion of each of said keepers having an inner vertical wall portion defining a complementary taper with the inner tapered face of one of said wedge elements and having an adjacent inner horizontal wall portion defining a complementary taper with inner tapered face of the other wedge element of the same pair, means adjustably-securing the one wedge element on an associated keeper with its inner tapered face in complementary wedging engagement with said inner vertical wall portion and with its outer planar face in cooperating slidable engagement with an end of said horizontal foot plate of the associated bracket, and means adjustably-securing the other wedge element of the same pair with its inner tapered face in complementary wedging engagement with said adjacent inner horizontal wall portion of the associated keeper and with its outer planar face in cooperating slidable clamping engagement with a top face of said foot plate of the associated bracket.
