Latest Patents
One of his latest patents is for a rotor designed for an axial flow rotary separator. This invention features radially extending finger-like crop-engaging elements that are individually and obliquely journaled on a fixed eccentric shaft. The design allows for push bars, spaced 90 degrees apart, to rotate about the axis of the separator, driving the fingers in a manner that maintains crop material in an annular mat. This mat is kept in contact with the inside wall of the casing, propelling it spirally downstream. Additionally, the finger element bearing housings are split for convenient assembly and repair.
Another significant patent involves a torque-responsive disconnect for a V-belt driven element in a combine harvester's threshing cylinder. This invention automatically adjusts drive belt tension based on the torque being transmitted. A linear hydraulic actuator, integral with the drive sheave, allows for the adjustment of an axially movable sheave half. This mechanism varies the effective diameter of the sheave, thus controlling the driven speed. The design includes a pressure switch that senses oil pressure, providing protection to the threshing cylinder and drive components from damage due to overload.
