Title: Joseph J Fisher: Innovator in Glass Shaping Technology
Introduction
Joseph J Fisher is a notable inventor based in Oakmont, PA (US), recognized for his contributions to glass shaping technology. He holds a total of 3 patents that showcase his innovative approaches in the field. Fisher's work has significantly impacted the manufacturing processes of glass sheets, particularly in the automotive industry.
Latest Patents
Fisher's latest patents include groundbreaking technologies such as the "In-lehr glass sheet press bending using pressurized gas." This invention involves positioning glass sheets on a shaping rail of an outline mold as they move through a heating lehr, followed by preliminary sag bending. The process utilizes a pair of vertically aligned pressing molds, where the lower mold features a full surface press face that corresponds to the desired curvature of the glass sheet. The upper mold, equipped with a peripheral shaping surface, uses pressurized gas to shape the glass effectively.
Another significant patent is the "Mold alignment means for glass sheet shaping apparatus." This apparatus is designed for shaping glass sheets into complex forms, incorporating both longitudinal and transverse bending components. It includes an outline mold that aligns the glass sheets for proper orientation while allowing gravity sagging to create the necessary bends. The innovative design ensures that when two glass sheets are shaped simultaneously, they conform perfectly to each other, facilitating the creation of laminated windshields that fit precisely within vehicle frames.
