Fiber Forming Bushing Construction
US Patent:
4155731, May 22, 1979
Filed:
Jan 11, 1978
Appl. No.:
5/868611
Inventors:
Gregory W. Byrnes - Eugene OR
Richard E. Ralls - Eugene OR
Richard E. Ralls - Eugene OR
Assignee:
The Greickor Company - Eugene OR
International Classification:
C03B 3702
US Classification:
65 1
Abstract:
In apparatus for heat-softening and attenuating glass material into fibers, an improved low temperature electrical resistance bushing having extremely thin side walls and other electricity conducting components running from end to end in the bushing, relative to the base plate for both direct and marble-melt bushings. The thin side walls enable a low temperature bushing to operate with temperatures less than 2250. degree. F. , because the thin side walls draw proportionately less current than the base plate. Additional improvements for providing a low temperature bushing include, for a marble-melt bushing, a funnel which is mounted on the top wall and a cooling tube mounted adjacent a bottom portion of the funnel. Another improvement includes the use of auxiliary end plates mounted adjacent the end walls of the bushing for channeling electrical current to the base plate. A further improvement in a marble-melt bushing includes the provision of opposed side walls which are inclined outwardly as well as extend upwardly from the base plate.
