Title: The Innovations of James H. Lucas
Introduction
James H. Lucas, based in Milwaukee, Wisconsin, is a notable inventor recognized for his contributions to mechanical engineering, particularly in the field of transmission systems. With a total of four patents to his name, Lucas has focused on innovations that optimize the functionality and efficiency of power shift transmissions.
Latest Patents
His latest patents encompass two significant inventions:
1. **Detent Mechanism and Transmission Speed Range Selector Valve** - This invention features a transmission speed range selector valve that is pressure-biased toward the high-speed range while being spring-biased toward the low-speed range. The design includes a detent mechanism that retains the valve in the low-speed range, which effectively arrests the valve's movement when the pressure biasing fluid decreases. This allows the spring to shift the valve towards the low-speed range, facilitating a downshift in the transmission when fluid is throttled to the speed range selector valve.
2. **Mechanical Detent for Three Speed Power Shift Transmission** - In this invention, Lucas has developed a mechanical detent release system for a power shift transmission selector valve. Operating through a mechanical linkage connected to the clutch pedal for the inching valve, this system releases the detent in response to a spring engagement with a cam on the clutch pedal. This coordination permits the selector valve to return to its low-speed position once the inching valve is activated.
