摘要： A mining machine movable along an armoured flexible conveyor each pan of which is provided with a rigid longitudinal guide rod for the machine, the machine having a winch-driven chain guided into a run alongside the guide rods, and each guide rod having a series of pockets housing pegs reciprocable towards and away from the run of the chain, each pocket being open to the chain and at the end remote from the chain open to a longitudinal slot along which a shoe carried by the machine is movable, and the shoe having tapering ends, so that as the shoe moves with the machine in either direction along the guide rods the pegs are urged to project from the pockets into engagement with the links of the chain in the run alongside the guide rods, to effect the driving of the machine along the conveyor.
