Abstract
Abstract In a ballast treating apparatus, wherein ballast is removed from underneath a track section, cleaned on a screen which separates the removed ballast into clean ballast and rubble, and the clean ballast is returned to the ballast bed, two overlapping conveyor bands are arranged to receive the rubble from the screen and move it away in opposite directions.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
168 words
An apparatus for treating ballast and adapted to move in a working direction on a track including rails fixed to ties resting on a ballast bed, comprising 1. a frame moving on the track rails; 2. a ballast removing chain means mounted on the frame and including a stringer extending horizontally and transversely underneath the track for removing ballast from the ballast bed; 3. a ballast cleaning screen mounted on the frame and separating the removed ballast into clean ballast and rubble; 4. a conveyor system for conveying removed ballast from the ballast removing chain means, and for conveying the clean ballast from the ballast cleaning screen to the ballast bed in a conveying path; and 5. further conveying means arranged to receive the rubble from the screen and for removing the rubble, the further conveying means including a first conveyor band arranged to move the rubble forwardly in the working direction and a second conveyor band arranged to move the rubble backwardly in respect of said direction.
Claim 2
Independent Claim
168 words
