Title: The Innovative Contributions of Evan Griffiths
Introduction
Evan Griffiths is a notable inventor based in Newington, CT (US). He has made significant contributions to the field of wire drawing technology, holding a total of 3 patents. His work reflects a commitment to advancing manufacturing processes and improving efficiency in wire production.
Latest Patents
Griffiths' latest patents include a "Method and apparatus for drawing and cooling wire." This invention features a dry lubricated wire drawing and cooling apparatus that comprises a die holder supporting a pair of dies in coaxially aligned and axially spaced relation. The design allows for a cooling chamber through which cooling liquid is circulated, ensuring that the drawn wire is effectively cooled. A sensing device is integrated to detect the approach of a wire end, which operates a mechanism to shut down the apparatus and expel cooling liquid from the chamber before the wire end reaches the first die.
Another significant patent is the "Multiple stage wire drawing machine." This invention includes a final stage draw block and multiple step draw capstan assemblies. Each assembly features a plurality of coaxial draw capstans of increasing diameter, which are rotatably mounted on a drive spindle. The system is designed to be driven at a fixed angular rate relative to the final stage draw block, with independent drive capabilities through friction disc slip couplings.
