J. H. WALBRIDGE BALLAST REMOVING MACHINE Filed Sept. 15, 1932 2 Sheets-Sheet l INVENTOR ATTORNEYS When it is desired to move the scraper to inoperative position, for example, when the machine is advanced through turn-outs or permanent highway crossings, the scraper members are disconnected as described above and swung into inverted position on top of the guide membe s as described above.

From the above description, it will be apparent to those skilled. in the art that I-provide an improved ballast removing machine which is highly effective in operationthe machine being provided with means for maintaining the true grade of the road bed. While I have not gone into detail concerning the means for controlling the operation of the various power units,'it will be understood that conventional controls are used. l j in order to facilitate the adjustment of the apparatus to a predetermined grade, pointer fingers 34 are provided which project laterally from some fixed part of the frame into position-to cooperate with a grade stake or the like.

I have illustrated and described my improve ments in an embodiment which I consider very practical. I haven-0t attempted to illustrate or describe other embodiments or adaptations, as it is believed this disclosure will enable those skilled in the art to embody or adapt my imadvancing said carriages.
