Introduction
Martin W. Coleman is an accomplished inventor based in Independence, MO (US). He holds a total of 2 patents that showcase his contributions to the field of hydraulic systems and agricultural machinery.
Latest Patents
One of his notable inventions is the "Closed-loop combine header height control." This innovation allows for the adjustment of the header height of a combine harvester from the operator's platform without the need to stop the machine. The system utilizes a variable capacitance that generates a continuous electrical header height signal, which is compared to a desired setpoint to maintain optimal height. The operator can easily control the height with a single switch, enhancing efficiency during operation.
Another significant patent is the "Hydraulic system combining open center and closed center hydraulic." This system features a single variable displacement pump that supplies hydraulic fluid to both open and closed center circuits. It ensures that the open center circuit receives a constant flow, while the closed center circuit only receives flow when needed. This design minimizes wear on the pump and allows for efficient operation at lower power inputs.
