Title: Innovations by Patrick Frank Sawyer
Introduction
Patrick Frank Sawyer is an accomplished inventor based in Birmingham, GB. He has made significant contributions to the field of vehicle hydraulic systems and braking systems. With a total of four patents to his name, Sawyer's work reflects a commitment to enhancing vehicle safety and functionality.
Latest Patents
One of his latest patents is for a liquid level contents indicator for vehicle hydraulic systems. This innovative device features a float-operated electric switch type mechanism that includes a manually operable push-button for circuit testing. The push-button interacts with the electric circuit through a resilient diaphragm, which also serves as a return spring and provides a seal between the push-button and the cap.
Another notable patent is for vehicle load sensing arrangements. This arrangement is designed for use with vehicle braking systems and includes an input member operating in a first bore, subjected to the force of a road spring. A robust helical coil spring applies an opposing force to the input member. The system features a valve with a valve member in a second bore, which has a smaller cross-sectional area than the first bore. The elastomeric member located between the input member and the valve member ensures that only a portion of the excess road spring force is transmitted to the valve member, enhancing the vehicle's braking efficiency.
