  • Patent number: 9174269
    Abstract: A tool is provided for connecting and disconnecting links of a conveyor chain. The tool includes a base, a chain guide plate mounted on the base for supporting a length of conveyor chain in a fixed position relative to the base, and a backup block carried on the base. A pin extraction/insertion block is positioned on the base with the chain guide plate positioned between the backup block and the pin extraction/insertion block. A ram is carried on the pin extraction/insertion block for extracting a pin from a position in aligned holes in adjacent links while the chain is held in its fixed position, and an insertion rod is carried on the pin extraction/insertion block for inserting a pin in aligned holes in adjacent links.
    Type: Grant

  • Patent number: 8485351
    Abstract: Disclosed is a multi-link conveyor that includes nestable end protector links that capture and retain link pins. The end protector link includes a first link segment having an outer wall, a non-circular bore having a cross-section larger than a cross-section of one of the pins, a circular counterbore connected to the non-circular bore and having a diameter larger than the head of one of the pins, and a circular countersink connected to the counterbore and having a first diameter that equals the diameter of the counterbore and a second diameter, flush with the outer wall, having a diameter larger than the first diameter. The end protector link includes a second link segment, adapted to nest with the first link segment of another end protector link, having an outer wall in a second vertical plane and a flush non-circular bore extending perpendicularly through the outer wall.

  • Patent number: 8356709
    Abstract: A nested end protector link for capturing first and second elongate link pins of a multi-link conveyor chain that includes a first link segment having an outer wall in a first vertical plane defining a protective bearing surface having a forward-facing convex face, and 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. A second link segment is integrally-formed with the first link segment and has an outer wall in a second vertical plane defining a protective bearing surface having a forward-facing concave face. A rearward-facing convex face is provided and has a second pin access bore extending perpendicularly through the link between the forward-facing concave face and the rearward-facing convex face.
