Title: Harold R. Hall: Innovator in Glass Sheet Technology
Introduction
Harold R. Hall is a notable inventor based in Whitehouse, Ohio, recognized for his contributions to the field of glass sheet technology. With a total of 2 patents, Hall has made significant advancements that enhance the manufacturing processes of glass products.
Latest Patents
One of Hall's latest patents is the "Glass Sheet Press Bending Mold." This invention provides an improved covering for continuous surface press bending molds, allowing for selectively variable rigidity to match the requirements of bending specific parts. The mold's shaping element features a resilient body with a latticework of flexible metallic bands encapsulated within it. This resilient body is further covered by multiple superimposed sheets of fibrous, heat-resistant material, topped with a layer of fiberglass cloth. Some of these fibrous sheets are treated with a rigidizer to achieve the desired rigidity.
Another significant patent is the "Method of and Apparatus for Bending and Tempering Thin Glass Sheets." This method involves bending and tempering relatively thin glass sheets while they are supported and conveyed along a horizontal path. The process includes heating the glass to its softening point, bending it into the desired curvature, reorienting it for further processing, reheating for proper tempering, and finally chilling the sheets rapidly below the annealing temperature range.
