Abstract
A gear rack is made up of rack segments arranged end-to-end supported by and extending along face conveyor for meshing engagement with a gear of a drive to propel a mining machine along a mine face. The teeth of each rack segment extend between longitudinal cheek sections. A thicker one of the cheek sections has a downward extending shoulder at each of opposite ends to engage in a cavity of a bracket and secured therein for limited movement by a fastener pin. A wall section of the bracket extends against a bearing surface formed by a cavity in the underside of the gear tooth at the end portion of the rack segment. The width of the wall section corresponds to the width of the bearing surface.
