Abstract
A conveyor for a flexible slurry hose of the type carried on a plurality of wheel-supported carts interconnected by an articulated linkage. The conveyor provides guidance and track means for transporting the carts and hose through a 180.degree. turn by lifting the wheels from the ground and guiding the linkage through the 180.degree. turn. The hose linkage and carts are guided through portions of an elliptical path before and after passing through an arc of a circle facilitating greater ease in negotiation of the entire turn, and a lesser degree of lateral displacement of the linkage than in systems guiding through a 180.degree. path of travel formed on a constant radius.

In a system for transporting a slurry from a mining machine in a mine having a floor and which includes at least one flexible hose supported by a plurality of spaced, wheeled carts, and further supported by a flexible linkage interconnecting the carts, which system further includes a mobile conveyor movably supporting some of the carts off the floor and a 180.degree. bend in the hose and linkage, and located between the storage section and a parallelly located active section as the need for the hose changes, the improvement comprising:
- means on said conveyor for guiding the linkage and hose supported thereon through a curving path defining said bend of 180.degree., which curving path includes a first portion having a radius of curvature which continually diminishes and a second portion having a radius of curvature which continually increases to complete said curving path.
