Title: Paul A Charles: Innovator in Gear and Composite Technologies
Introduction
Paul A Charles is a notable inventor based in Rockford, IL (US), recognized for his contributions to the fields of gear manufacturing and composite materials. With a total of four patents to his name, Charles has made significant advancements in the methods and mechanisms used in these industries.
Latest Patents
Among his latest patents is a method of generating involute tooth forms with a milling cutter. This innovative technique involves positioning a rotating milling cutter to cut an involute external tooth profile into the periphery of a gear blank. The process ensures that the cutter's path is perpendicular to the plane of action of the desired base surface, allowing for precise generation of the involute profile as the base surface rolls upon the plane of action. This rolling action enables the generating line to traverse the blank effectively, ensuring the desired length of the active profile is achieved.
Another significant patent by Charles is the tape-laying head, which discloses a mechanism and method for constructing sheet layments of composite resin-embedded filamentous material in incremental tape form. This innovative design features a pair of tape-laying heads mounted side by side for simultaneous operation, allowing for efficient and controlled movement of the tape-laying subcarriage. The mechanism enables lateral indexing while drawing out the tape, ensuring a seamless laying process without the need for the entire mechanism to move.
