ABSTRACT:
A scraper-chain conveyor is composed of a series of channel sections arranged end-to-end with shaped components on one side defining a guide for a machine such as a plough. Each component has a tubular track or rail at its upper end and these rails are spaced apart to receive coupling devices. Each device has a cylindrical body matching the rail profile and located between adjacent rails. Spigots engage with clearance in these rails; one spigot being integral with the body and the other spigot being slidable within the body so as to retract or extend therefrom. A recess in the body receives a block which is detachably secured to the body to prevent the slidable spigot from retracting.
