Title: Innovations by James G Fulmer
Introduction
James G Fulmer is an accomplished inventor based in Addison, IL (US). He has made significant contributions to the field of fastening technology, particularly through his innovative designs of thread-forming screws. With a total of two patents to his name, Fulmer's work exemplifies the intersection of engineering and practical application.
Latest Patents
Fulmer's latest patents include a unique thread-forming screw with a tri-roundular, tapered end. This design features a tapered end portion with a tri-roundular cross-section, incorporating three spaced flats and three threaded, round portions arranged alternately around the screw's periphery. The manufacturing process involves inserting a tapered blank between paired dies, which have threads with undulations that correspond to the screw's circumference. This results in a trilobular thread that spirals around the screw, enhancing its functionality. The tapered end is designed to provide relief from contact with the workpiece, facilitating easier driving of the screw while ensuring a high strip force.
Another notable patent by Fulmer is a thread-forming screw that also features a tapered end portion. This design is created by inserting a cylindrical blank between paired dies, which have both straight and tapered portions. The undulating threads on the dies form a trilobular thread that spirals around the screw. This design increases material at the tapered thread-forming location, allowing for fully crested threads and greater stress relief, which reduces the force required for thread formation.
