Abstract:

An improved link for a grate conveyor or the like, which is an elongate casting having at a first end thereof a pair of transversely spaced side walls and at the other or second end thereof a lug having a width generally corresponding to the width of the space between said walls and extending out endwise at said second end. The lug is adapted to fit between the spaced side walls of the next link in a series of links making up the chain. The side walls have aligned holes therein of circular cross section coaxial on a first axis extending transversely of the link adjacent its first end. The lug also has a hole therein of circular cross section on a second axis extending transversely of the link adjacent its second end wherein the second axis is parallel to the first axis. The link is cast of a metallic material and has inserts of a harder material extending partially around the circumference of each of the holes in said side walls at that side of each of those holes toward the first end of the link and an insert of a harder material extending partially around the circumference of the hole in the lug at that side of the hole toward the second end of the link.
