  • Patent number: 4489828
    Abstract: A steel connector for joining the steel cable ends of a conveyor belt is provided. The connector comprises a pair of tubular sleeves--one of which is slipped onto each cable end. Each sleeve has a bore having an inner section of reduced diameter relative to the outer section. The cable end is expanded radially, by driving a cone into its end, and then the expanded end is wedged tightly into the inner section of the sleeve to fix them together. Bridging members are threaded into the outer sections of the two sleeves to hold them together in lineal alignment. The bridging members are operative to permit the sleeves to flex relative to each other.
