Title: The Innovative Contributions of Henry Joseph Spence

Introduction

Henry Joseph Spence is a notable inventor based in Indianapolis, IN, who has made significant contributions to the field of hydraulic coupling technology. With a total of three patents to his name, Spence has focused on developing solutions that enhance the efficiency and functionality of internal combustion engines.

Latest Patents

Spence's latest patents include the "Rolling Dam Temperature Controlled Hydraulic Coupling" and the "Temperature Controlled Hydraulic Coupling with Moveable Dam." The rolling dam hydraulic coupling is designed to couple the engine to the radiator fan of an internal combustion engine. This innovative coupling features a rolling dam adjacent to the dump hole, which connects the drive chamber containing the drive rotor with a shear liquid reservoir passageway. The dam can roll between two abutments carried by the housing cover, allowing it to assume one of two positions relative to the dump hole. This design accommodates relative rotation between the drive rotor and coupling housing in both directions, ensuring optimal performance.

The second patent, the temperature-controlled hydraulic coupling with a moveable dam, also aims to couple the engine to the radiator fan. This coupling includes a pivotable dam that can assume two angular positions upon assembly. Each position allows for relative rotation of the drive rotor and coupling housing in different directions. The pivoting action of the dam enables it to contact the periphery of the drive rotor, further enhancing the coupling's efficiency.
