Abstract
A bent wire link type chain wear inspection apparatus for measuring the section thickness of a chain link to determine the limit of permissible wear thereof comprising a device (1) having a plurality of slots (5-14) therein uniquely identified with respect to chain size and used to establish the continued serviceability of chains from a wear standpoint. Each of the slots has an opening smaller than the identified chain size and which is preferably equal to the minimum acceptable link section size. Acceptable chain links are therefore excluded from fitting into the opening whereas worn chain links which have been worn to a degree which equals or exceeds the limit of permissible wear slide into the opening thereby indicating that the chain should be removed from service.
