ABSTRACT:
A thrust device for a coal cutter running on a sectional string of trunking of a chain conveyor comprises a pinion on the coal cutter cooperating with a rack located on the conveyor. The rack is formed of a plurality of linked sections only one of which is firmly attached to the conveyor, the other sections being guided for longitudinal movement relative to the conveyor. The purpose of this arrangement is to avoid straining the rack or producing tooth pitch variations at the junctions of adjacent rack sections when the trunking flexes due to geological disturbances.
