Title: The Innovative Contributions of William Workman, Jr.

Introduction

William Workman, Jr. is a notable inventor based in Spring Lake, MI (US). He has made significant contributions to the field of fluid-driven motors, holding a total of 8 patents. His inventions focus on enhancing the efficiency and safety of fluid-powered systems.

Latest Patents

One of his latest patents is a shut-off device for a fluid-driven motor. This invention relates to a device that shuts off the supply of pressurized motive fluid to a fluid-driven motor in response to a predetermined motor back pressure. The device features a housing with a fluid inlet and outlet, a passageway, and a shut-off piston that closes the passageway when necessary. Additionally, it includes an orifice of variable size controlled by a pilot piston, allowing for precise pressure management to the motor. This innovation ensures that the final shut-off torque of the motor can be accurately controlled, regardless of the load encountered.

Another significant patent is the safety shut-off mechanism for swing bar tools. This mechanism comprises a reaction torque structure that rotates in the opposite direction of the motor under load. It includes a swing-bar for restraining the reaction torque structure, a reference structure for movement tracking, and a locking structure actuated by fluid pressure. The shut-off structure deprives the motor of motive force in response to relative movement between the reaction torque structure and the reference structure upon failure of the swing-bar. This invention enhances the safety of fluid-powered motors.
