Abstract
Linear induction motors are mounted above the bath of molten metal employed in the production of a float glass ribbon to direct dross from the surface of the metal into dedrossing motors are suspended from a retracting mechanism mounted on the upper external bath structure so that they can be quickly raised from their operative position when desired, thus permitting unhindered access therebeneath to the side areas of the bath.
Claims8
In apparatus for producing float glass including an elongated tank containing a bath of molten metal upon which the glass is floated in ribbon form, an enclosed chamber over said tank including a roof structure spanning opposite side walls, said opposite side walls being spaced above corresponding walls of said tank to define an access opening therebetween, and regulating means extending through said access opening into said enclosed chamber, the improvement comprising a retractable carrier suspending said regulating means entirely from above whereby said regulating means can be vertically raised while retaining its original attitude from a lowered operative position along said tank to an elevated storage position permitting unhindered access therebeneath to said chamber, and means defining an opening in the side wall communicating with the corresponding access opening and extending upwardly toward said roof structure for receiving said regulating means as it is raised to said elevated storage position.
