A machine to remove gob from railroad tracks, between rails, and to a distance
of 48 in (1.2 m) from the track centers. Digger plates remove gob to the top of
ties, while wings on either side of the machine gather it from the sides of the
track into the track, to be moved by conveyors to a car at the machine's rear.
One person operates the towing motor and observes the digging, while another
controls the digging plate height, adjusts wing plows, and observes loading. Best,
