Abstract
The pans of a scraper-chain conveyor are interconnected by way of a dog-bone type connector with enlarged end regions and a central shank which fits into shaped compartments in the side walls of adjacent pans. A hook-like projection on one of the end regions engages in a recess adjoining one of the pockets and a complementary web-like projection on the other end region lies in an opening adjoining the other of the pockets. A swivelling locking plate is fitted to the side wall to overlap the web-like projection and retain the connector in place.
