Abstract
A mining apparatus has a longitudinally extending conveyor, a guide-rail assembly secured to the conveyor and forming an upwardly open cruciform passage, a drive chain in the passage, and a mining machine displaceable along the assembly and having a toothed drive wheel engageable in the chain in the passage. The rail assembly is formed by a main rail fixed to the conveyor and forming a portion of the passage and a secondary rail fixed to the main rail and forming the rest of the passage. The secondary rail forms offset from the passage a horizontally outwardly open and longitudinally extending slot and the mining machine has a foot received in and longitudinally displaceable along the slot.
Claims8
In a mining apparatus having
- a longitudinally extending conveyor;
- a guide-rail assembly secured to the conveyor and forming an upwardly open cruciform passage extending a full length of the assembly;
