Title: The Innovative Contributions of Donald G. Davey
Introduction
Donald G. Davey is a notable inventor based in Oregon, Ohio, recognized for his contributions to the field of glass manufacturing. With a total of 2 patents, he has made significant advancements in the technology surrounding cathode ray tubes and glass processing.
Latest Patents
One of his latest patents is titled "Method of and apparatus for press forming cathode ray tube faceplate." This invention features a cathode ray tube faceplate press equipped with an indexing table that rotates around a column normal to the table. The design includes a circular array of female molds that are concentric with the column. The indexing speed of the table is optimized by a barrel cam drive, which allows for smooth acceleration and deceleration that can be tolerated by the molten glass in the molds. A cam dwell precisely registers the table work stations, eliminating the need for register pins and the delays they introduce. The acceleration and deceleration peak at about the one-eighth and seven-eighths positions of the drive cycle, following a generally sinusoidal form.
Another significant patent is the "Multiple gob shearing apparatus." This apparatus is designed for severing gobs that issue from a glass feeder. The shearing mechanism consists of two sets, or pairs, of shear blades mounted from diametrically opposed positions relative to the bowl of the feeder. A single cam drives through multiple linkage mechanisms to operate the two pairs of shear mechanisms in synchrony, ensuring that the gobs are all sheared at the same instant. The links in the linkage mechanism are adjustable in length to provide the necessary adjustments after setup, ensuring the proper operation of the shears.
