ABSTRACT:
This invention relates to a stop adapted for attachment to outline molds of different outline configurations defining shapes of different depths of bend desired for glass sheets to be shaped to different patterns. The stop comprises a glass engaging member of disc-like configuration having a front surface oriented to face an edge surface of a glass sheet to be mounted in engaging relation to said front surface when loaded onto a selected one of said outline molds. The glass engaging member of disc-like configuration is supported in eccentric relation to a rod supported in fixed relation relative to a localized portion of an upwardly facing shaping surface defined by a shaping rail of said selected outline mold. When the glass engaging member of disc-like configuration is rotated about an axis defined by the rod, the vertical dimension of the glass engaging member of disc-like configuration above the rod is changed to correlate with the height of stop needed to engage an edge of the glass sheet to be bent to a shape conforming to that developed by the outline mold.
The present invention makes it possible to provide an inventory of identical stops for many different production patterns to be fabricated. In addition, a simple rotational adjustment often enables a stop to be continued in use rather than requiring replacement under certain circumstances when the stop becomes damaged during use.
