Title: Innovations by John A Louw
Introduction
John A Louw is a notable inventor based in Rancho Palos Verdes, CA (US). He has made significant contributions to the field of manufacturing, particularly in the development of fluted pin fasteners. With a total of 6 patents to his name, Louw's work showcases his innovative approach to engineering and design.
Latest Patents
Louw's latest patents include a Rotary Drum Holder and a Five Spindle Fluting Machine. The Rotary Drum Holder patent describes a new machine and method for manufacturing fluted pin fasteners. This invention utilizes a circular grinding arrangement with multiple grinders to create flutes in threaded pins. An internally threaded collar threads onto the pin, and as it engages a workpiece, resistance to further threading increases. When sufficient resistance occurs, the driver deforms the collar's lobes radially inward, allowing material to flow into the flutes of the pin, effectively locking the collar, pin, and workpiece together. The grinding apparatus includes a vibratory feed bowl and a four-station rotary drum assembly, which operates simultaneously to enhance production efficiency.
The Five Spindle Fluting Machine patent also focuses on manufacturing fluted pin fasteners using a similar circular grinding arrangement. This machine operates with a vibratory feed bowl and a rotary drum assembly, ensuring high production rates by grinding multiple pins at once.
