Abstract
A machine for automatically setting rail tie plates includes a frame adapted to be propelled along a rail bed having one or both rails removed, the frame including a hopper adapted to store a plurality of randomly oriented plates therein, a crane for transferring plates to a plate sorting conveyor which sorts the plates as to specified length-to-width orientation and deposits the oriented plates upon an inclined conveyor where they are sensed as to specified top-to-bottom orientation, with improperly oriented plates being automatically inverted; the sensed and inverted plates are then manually disposed as to proper high-to-low side orientation, from where they are stored for eventual automatic deposition upon the tie by a reciprocating pusher assembly.
