Title: The Innovations of Jonathan E Mccallum
Introduction
Jonathan E Mccallum is an inventive mind based in Edmonton, Canada. He has made significant contributions to the field of fan technology, particularly with his innovative designs for variable pitch fans. Although he currently holds no patents, his work showcases a deep understanding of mechanical engineering principles.
Latest Patents
Mccallum's latest patents include the "Blade For Variable Pitch Fan" and "Variable Pitch Fan Having A Pitch Sensor." The first patent describes a fan blade mounted on a shaft that can vary in pitch through rotation about a pitching axis. This design features a center of mass offset from the shaft, which effectively reduces torque around the shaft or pitching axis. The second patent outlines a compact variable pitch fan equipped with a drive fluid pitch change mechanism. This mechanism allows a pitch change piston to follow reciprocating motion under drive fluid control within a peripheral hub, from which the fan blades extend outward. A pitch change sensor is also integrated with the rotary union.
