Abstract:
1. A tool for connecting and disconnecting links of a conveyor chain of the type wherein the links are held together by chain pins that extend transversely through aligned holes extending across a width of the conveyor chain formed by rows of interlocked links, and around which the interlocked links pivot as they travel around a conveyor circuit, comprising: (a) a base; (b) a chain guide plate mounted on the base for supporting a length of conveyor chain in a fixed position relative to the base; (c) a backup block carried on the base; (d) a chain pin extraction/insertion block for being positioned on the base with the chain guide plate positioned between the backup block and the chain pin extraction/insertion block; (e) a ram carried on the chain pin extraction/insertion block for extracting a chain pin from a position in aligned holes in adjacent links while the chain is held in its fixed position, and including a guide tip coaxially-surrounding an extraction pin carried on an end of the ram for coaxially-engaging an end of the chain pin; and (f) an insertion rod carried on the chain pin extraction/insertion block for coaxially-inserting a drive pin into a bore in the end of a chain pin in aligned holes in adjacent links.
