ABSTRACT:
A system for repairing a continuous loop chain includes a plurality of pairs of chain links, each link having a pair of straight, substantially parallel side bars. Each pair of chain links has an outer link having a first width between the outer link side bars, and an inner link having a second width between the inner link side bars. The second width is less than the first width such that the side bars of the inner link are adapted to fit between the side bars of the outer link. The outer links and inner links are pivotally joined to each other. A repair link having a pair of offset side bars is adapted to connect on one end to the inner link of one of the pairs of chain links and on the other end to the outer link of another one of the pairs of chain links. In this way, a defective link, or a pair of defective links, can be replaced by one or more of the repair links. Such a system, apparatus, and method provides means useful for repairing a linked chain in a tobacco bulk silo utilized in manufacture of smoking articles.
