Compressed, Wedged Float Glass Bottom Structure

US Patent:
5007950, Apr 16, 1991
Filed:
Dec 22, 1989
Appl. No.:
7/455046
Inventors:
Bert K. Krushinski - Murrysville PA
Robert A. Lawhon - Chehalis WA
Francis A. Radecki - Ross Township, Allegheny County PA
Ronald L. Schwenninger - Ridgely WV
Assignee:
PPG Industries, Inc. - Pittsburgh PA
International Classification:
C03B 1802
US Classification:
651825
Abstract:
In a float glass chamber, particularly in a region operating at higher than usual temperatures, integrity of the bottom structure is sustained by employing wedge shaped bottom blocks that are maintained in compression by externally applied mechanical forces. The arrangement permits the use of a bi-layer bottom construction with a high alumina upper course and a clay bottom course.
