Claims16
Apparatus for sealing between edge control machines and forming chamber sidewalls comprising support means, collar means mounted to said support means and slidably surrounding the barrel of said edge control machine, means mounted between said edge control machine and said collar for maintaining movement of said collar in a vertical plane relative to said support means in order that it does not bind during movement of said barrel of said edge control machine, and a flexible sleeve fastened to said collar and to said forming chamber sidewall.
In an apparatus for making flat glass wherein the position of a marginal portion of a body of glass supported on a pool of molten metal in a chamber is controlled to establish and maintain a desired width and thickness of the glass, the combination comprising:
- (a) structural support means mounted outside said chamber,
- (b) a carriage, including a carriage frame, adjustable mounting means and a mounting platform on said structural support
- (c) an elongated member mounted on said mounting means and being extendable through a side wall and over the pool of molten metal
- (d) means for engaging glass supported on said molten metal mounted on said elongated member and providing means for applying a force to the glass wherein said elongated member is capable by means of a carriage movement and adjustable mounting movement of moving said means for engaging the glass in directions upward, downward, upstream, downstream, into said chamber and out of said chamber;
- (e) collar means slidably surrounding said elongated member, means between said mounting platform and said collar for maintaining movement of said collar in a plane vertically aligned with said elongated member and a flexible sleeve fastened to said collar and to said chamber sidewall.
