Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
193 words
A mobile apparatus for distributing and shaping the ballast of a railroad bed whereon there are supported two track rails, comprising 1. a frame, 2. two undercarriages mounting the frame on the track rails for mobility thereon, 3. two ballast plows mounted on the underside of the frame between the undercarriages, a. each plow being associated with a respective one of the track rails and comprising b. two transverse plates spaced apart in the direction of the associated track rail, c. the two transverse plates of each plow extending obliquely to the associated rail, d. opposite ones of the transverse plates of the two plows extending in common planes, e. the planes wherein the opposite transverse plates of the plows extend intersecting in a vertical line of intersection intermediate the two track rails, and f. the transverse plates defining a transverse space therebetween extending longitudinally of the track rails, 4. an intermediate ballast guiding part comprising a plurality of ballast guiding plates pivotal about the vertical line of intersection, and 5. means for pivoting the ballast guiding plates to close the traNsverse space between selected ones of the transverse plates of the plows.
