Title: The Innovative Contributions of William L Hillis
Introduction
William L Hillis is a notable inventor based in Lawrenceburg, TN (US), recognized for his contributions to gas valve technology. With a total of 4 patents to his name, Hillis has made significant advancements in the design and functionality of gas valve assemblies.
Latest Patents
Hillis's latest patents include the Staked Dual Valve Assembly, which features a gas valve assembly designed for use with gas grills. This innovative assembly incorporates a t-shaped manifold with an inlet fluid port that branches into a pair of valve ports. Each gas valve is equipped with an outwardly extending neck that fits into the manifold's valve ports. The design includes a stop means that positions the valves at a predetermined distance from each other, enhancing manufacturability. Additionally, an anti-rotation feature minimizes any rotation between the valves and the manifold, ensuring stability and reliability.
Another patent for the Staked Dual Valve Assembly describes a gas manifold assembly that connects to at least one gas valve. This assembly also features an inlet fluid port that branches into a delivery port. Each delivery port receives a protrusion from the valve, which is crimped together to form a collar. A stop offsets the valves to improve manufacturability, while a flattened portion of the protrusion engages the fitting, creating an anti-rotation feature once crimped. Seals between the fitting and the valve enhance joint integrity, further improving the assembly's performance.
