Title: Innovations by James E. Humphries in Air Driven Pumps

Introduction

James E. Humphries is a renowned inventor based in Hesperia, CA, with a remarkable portfolio that includes two patents. His work primarily focuses on the development of air-driven pumps, showcasing his expertise in mechanical engineering and innovative design.

Latest Patents

One of his latest patents encompasses an air-driven double diaphragm pump. This innovative design features two opposed pump chambers complemented by an air motor with air chambers in between. The configuration of the pump chambers and air chambers forms distinct pumping cavities that are divided by diaphragms. Each pump chamber is equipped with an inlet ball valve and an outlet ball valve, ensuring efficient flow management. The inlet manifold is strategically placed below the pump chambers, while the outlet manifold is positioned above them.

Tie-rods are a critical aspect of this design, extending across the pump from one chamber to the other, placing the entire assembly under compression. Additionally, tie-rods extend from the outlet manifold through the pump chambers to the inlet manifold, with feet mounted below for stability. The design incorporates two plates flanking the air motor, which connect to grooves in both the inlet and outlet manifolds as well as the pump chambers, providing structural integrity.

An outlet manifold facilitates remote air exhaustion, enhancing usability. The innovative ball valves feature small diametrical clearances and limitations on lift for improved performance, and they are sealed with O-rings and finely polished surfaces for optimal function. Belleville washers are utilized to mitigate thermal stress on the tie-rods, ensuring durability. The diaphragms are integrally molded, incorporating complex features for attachment that prevent air chamber contamination, demonstrating a high level of engineering sophistication.
