Patent number: 9873570Abstract: A system and method for discharging material from a chute on a farm implement into a container or bin such that the discharged material is evenly distributed in the container or bin. The system and method includes a farm implement with a bin for holding material, a conveyor for discharging material from the bin and a chute at the end of the conveyor for directing the material discharged from the conveyor. The chute may be moved into a plurality of positions based on sensor outputs to facilitate the even distribution of material in the container or bin receiving the discharged material.Type: GrantFiled: February 26, 2016Date of Patent: January 23, 2018Assignee: Unverferth Manufacturing Company, Inc.Inventors: Michael Van Mill, Ronald J. Schlimgen, Shawn W. Gerdeman

Patent number: 9487990Abstract: A door control system for a farm implement with a storage bin having a discharge opening and a door movable by a drive mechanism between open and dosed positions relative to the discharge opening includes a dual position door control system. The system may include an arm pivotally connected at one end to the storage bin such that the arm is rotatable between at least a first operating position and a second operating position and a controller connected to the arm and to the drive mechanism.Type: GrantFiled: March 14, 2013Date of Patent: November 8, 2016Assignee: Unverferth Manufacturing Company, Inc.Inventors: Michael Van Mill, Ronald J. Schlimgen

Patent number: 8967727Abstract: A gravity wagon includes a container for storing grain or other material and a discharge for allowing material to exit the hopper via gravity. A discharge chute and kickback are used to direct the material from the discharge and are coupled via a linkage such that they can be positioned to direct the material exiting the hopper to an area generally to the side of the hopper in a first position or an area generally towards the center of the hopper in a second position. The movement of the discharge chute and the kickback between the first and second positions is facilitated by a pusher or pushing member coupled to the kickback.Type: GrantFiled: July 2, 2012Date of Patent: March 3, 2015Assignee: Unverferth Manufacturing Company, Inc.Inventors: Michael Van Mill, John Walvatne, Daryl Rubner

Publication number: 20080048414Abstract: An oscillating in-line steering system for a pulled agricultural implement includes first and second in-line axles pivotably coupled with a frame. The system also includes at least first and second in-line wheel arrangements pivotably coupled with the first and second axles respectively. Each wheel arrangement has a plurality of pivotable wheel assemblies arranged in-line and wheel linkages coupling the in-line wheel assemblies such that in-line wheel assemblies oscillate together. A right-to-left linkage couples the wheel linkage of the first in-line wheel arrangement to the wheel linkage of the second in-line wheel arrangement so that the first in-line wheel arrangement oscillates at a steering angle proportional to that of the second in-line wheel arrangement.Type: ApplicationFiled: August 21, 2007Publication date: February 28, 2008Applicant: Unverferth Manufacturing Co., Inc.Inventors: Michael Van Mill, Ron Schlimgen, John Walvatne
