Patent ID: 8322522

Claim:
A multi-link conveyor chain, comprising: (a) a plurality of conveyor links interconnected in a lengthwise direction and a widthwise direction by a plurality of laterally-extending pairs of link pins positioned in respective pairs of bores therethrough to form a conveyor having a horizontal supporting surface for transporting successive items downstream in a processing line by engagement with a driving element; (b) a plurality of end protector links for capturing and retaining the plurality of link pins and for being engaged by wearing surfaces past which the conveyor moves and protecting enlarged heads of the link pins to exposure to said wearing surfaces, comprising: (i) a first link segment having an outer wall in a first vertical plane defining a protective bearing surface having a forward-facing convex face, a rearward-facing concave face and a first pin access bore extending perpendicularly through the link between the forward-facing convex face and the rearward-facing concave face; (ii) a second link segment integrally-formed with the first link segment and having an outer wall in a second vertical plane having a forward-facing concave face, a rearward-facing convex face and a second pin access bore extending perpendicularly through the link between the forward-facing concave face and the rearward-facing convex face; (iii) the forward-facing convex face of the first link segment and the forward-facing concave face of the second link segment having respective complementary arcuate shapes adapted to nest with and move relative to a respective rearward-facing concave face and rearward-facing convex face of a like end protector link forward of the end protector link to which the end protector link is nested in the conveyor chain; (iv) the rearward-facing convex face of the second link segment and the rearward-facing concave face of the first link segment having respective complementary arcuate shapes adapted to nest with and move relative to a respective forward-facing concave face and forward-facing convex face of a like end protector link rearward of the end protector link to which the end protector link is nested in the conveyor chain, a top half and bottom half of the end protector link being mirror images of each other on either side of a notional longitudinal axis bisecting the first and second access bores, wherein the end protector link may be utilized on opposite side edges of the conveyor chain by rotating the end protector link 180 degrees about the notional longitudinal axis bisecting the first and second pin access bores while maintaining the forward-facing convex face in its forward-facing orientation; and (c) the enlarged heads of the link pins extending through and captured in respective ones of the first and second link pin access bores.
