Schellens Blocking Devices?

Posted by Anonymous on Friday, February 8, 2002 9:54 PM

Does anyone know the history of the Schellens Blocking Devices (Germany)? What are they? I am doing genealogy research and came across this in connection with my Great-Grandfather, Hermann Schellens, a railroad man of the Rhine Provences, Germany in the 1800's. I would love to know more about his invention. You can reach me at: ljcarter6@austin.rr.com
