ABSTRACT:
A railroad tie adzer has a cutter head and means for rotating the cutter head to surface the tie plate area of a tie. A cutter guard extends peripherally about the path of rotation of the cutter head, and there is a vacuum duct opening into the cutter guard to remove debris during the adzing operation. A volute deflector is positioned within the cutter guard and extends partially about and outside of the path of movement of the cutter head. The volute deflector extends from adjacent the vacuum duct circumferentially in the direction of cutter head movement. There is an inclined ramp adjacent the entrance to the vacuum duct to direct debris from adzing, moving in a volute or spiral pattern, as defined by the deflector, into the vacuum duct. The vacuum duct is connected to a fan which in turn is connected to a separator from which the separated dust and debris are discharged away from the adzer.
