ABSTRACT:
A guide for mineral mining machines is composed of assemblies each secured to the mineral face side of a conveyor. The assemblies have angle plates secured to the side walls and structures formed with spacers separating upper and lower passages for a drive chain. Covers are detachably and pivotably mounted to the structures. The covers can be secured in a closed position covering the upper passage or swung outwardly to an open position on push-in hinge joints formed at their lower regions by interengaging components of the covers and the structures. The hinge joints have complementary projections and recesses which interengage when the covers are closed.
