Patent number: 11045972Abstract: A flail chain link comprises a plurality of adjacent link sections including a pair of oppositely disposed end link sections. Each end link section has an internal surface, and a first axis passes through the center point of the link and the center of each end link section. A second axis, which is not coincident with the first axis, passes through the center point and the center of at least two link sections. The first axis and the second axis together define a central plane through the center of each link section. An orthogonal plane passing through each of the end link sections is perpendicular to the central plane. A radius of the internal surface of each end link section that is measured in the central plane is equal to a radius of the internal surface of such end link section that is measured in the orthogonal plane.Type: GrantFiled: April 10, 2019Date of Patent: June 29, 2021Assignee: Astee Industries, Inc.Inventors: Nathan Anderson, Arnold Neil Peterson
