Title: The Innovative Contributions of William P. Cathers
Introduction
William P. Cathers, an accomplished inventor based in Allison Park, PA, has made significant strides in the field of glass manufacturing. With a remarkable portfolio of 11 patents, Cathers continues to push the boundaries of innovation, particularly in the design and processing of glass sheets.
Latest Patents
Cathers' latest patents showcase his commitment to improving the glass bending process. One of his notable inventions, "In-lehr press bending," outlines a method where glass sheets are meticulously positioned on a shaping rail before navigating through a heating lehr. This innovative technique allows for preliminary sag bending before the mold, now equipped with selected press surface areas that extend beyond its perimeter, lifts the glass sheet. As the lower mold elevates, portions of the shaping rail adjust to enable smooth passage, culminating in a flawless pressing between the upper and lower molds.
Another significant contribution is his "Method and apparatus to reduce tip curl of a glass sheet on a bending." This invention addresses the challenges posed by sag bending on intricate glass shapes. A pivoting assembly, equipped with a glass edge roller, skillfully maintains contact with the glass edge while traveling through the heating lehr or bending mold, effectively biasing the glass against the bending rail to minimize tip curl.
