Abstract
A chain link plate including a pair of enlarged end parts joined by an intermediate constricted part. Each end part has an opening therethrough. The link plate is symmetrical about a first axis which extends longitudinally of the link plate and passes through the centers of the openings. The link plate is also symmetrical about a second axis which extends perpendicular to the first axis and perpendicular to the axes of the openings. Each end part has a convex curved exterior edge surface generated about a first radius which is centered on the first axis. The intermediate constricted part has upper and lower concave curved exterior edge surfaces each defined about a second radius which is generated about a center point located in sidewardly spaced relationship from the link plate. The second radius is equal to the first radius. The concave curved exterior edge surface of the constricted part merges with the convex curved exterior edge surface of the adjacent end part along a common line which is tangential to both curved exterior edge surfaces.
