  • Connector for attaching items to a chain for a packaging machine
    Patent number: 5857558
    Abstract: A connector for attaching items to a chain typically used on packaging machines. An elongated body spans two extended link pins of a chain, and has at least one hole for attaching items. Offset tabs on each end of the body receive a link pin and allow tabs of adjacent connectors to overlap and pivot on the same link pin. A series of connectors can be installed adjacently on an endless chain to create a top and bottom surface to which items can be attached. The connectors manually install across two link pins of a chain and can be easily replaced if needed without untensioning or disassembling the chain. Retainers are not needed for the connectors when chains are used in pairs and items are attached between the two chains.
