Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
142 words
Apparatus for grinding a railway wheel in an upright position comprising a grinding station, an entrance rail and an exit rail leading respectively to and from said station, a plurality of supports mounted at said station, a pair of opposed frames connected to said supports and vertically movable with respect thereto, a grinder pivotally suspended from each frame, power means for urging each grinder against a wheel, a pair of rollers beneath and between said frames and said grinders said rollers being adapted to rotatably support a wheel in an upright position, means for rotating at least one of said rollers, means for adjusting the vertical position of each frame on said supports to enable chamfering of said wheel, and means for stopping a wheel on said rollers entering from said entrance rail and thereafter ejecting said wheel onto said exit rail.
