Title: Innovations by Don Hiller: Pioneering Valve Lock Mechanisms

Introduction

Don Hiller, an accomplished inventor based in Slidell, Louisiana, has made significant contributions to the field of valve locking mechanisms. With a total of two patents to his name, his innovations demonstrate a deep understanding of mechanical design and functionality, particularly in safety and operational efficiency.

Latest Patents

Hiller’s latest patents include the "Adjustable, fusible, manually operable valve lock-open assembly" and the "Pilot valve with fusible lockout knob."

The first patent describes an actuator shaft heat-sensitive locking apparatus featuring a cylindrical housing with an axial bore. This design allows for an adjustable shaft link that can cater to gate valve actuator shafts of varying lengths. It incorporates a fusible element that can transition between a solid state, where it prevents movement of the shaft link, and a heat-responsive state, enabling movement based on temperature changes. The innovative mechanical release means integrated into the design supports remote operation, enhancing user convenience and safety.

The second patent presents an apparatus for manually locking a pilot valve in an ‘in service’ position, independent of pilot fluid pressure. This system can either be manually disengaged or automatically reset when temperatures exceed a certain threshold. A unique feature is the ‘L’ shaped locking member that secures the valve in place, with an indicating surface to show when it is locked. This locking member is made from fusible material that returns the valve to its operational mode when certain temperature conditions are met.
