  Verfahren, um abgenutzt   Eisenbahnechlenen   wieder   gebrauchsfähig zu machen.   



   Den Gegenstand der vorliegenden Erfindung bildet ein neues   Verfahren, abgenützte   Fäsenbahnschienen wieder gebrauchsfähig herzustellen. Bisher war es unmöglich, die durch den Gebrauch an ihren Köpfen   ausgefransten   und abgeplatteten   Stahlschienen   durch Nachwalzen wieder in brauchbaren Zustand zu bringen, da diese Fransen   ausserordentlich   zähe sind, indem sie sich gleichsam durch einen Kaltwalzprocess bilden. Da man die Schienen behufs des Umwalzens nicht wieder der   Schweisshitze   aussetzen kann, so vereinigen sich die Fransen nicht   vollkommen   mit den abgeplatteten Theilon der Schienenköpfe, so dass

   Bei dem nachstehend beschriebenen Verfahren werden die Fransen durch Abschleifen entfernt, so dass es möglich wird, die Schienen   umzuwälzen,   wobei sie ihre   gleichmässige   Struktur ohne Sprünge und Risse beibehalten und einen   gleichförmigen   Querschnitt er-

  Process to make worn railroad hooks usable again.



   The subject of the present invention is a new method of making worn Fäsenbahnschienen usable again. Up to now it has been impossible to bring the steel rails, which have been frayed and flattened on their heads, back into a usable condition by re-rolling, since these fringes are extremely tough, being formed, as it were, by a cold rolling process. Since the rails cannot be exposed to the heat of welding again for the purpose of rolling them over, the fringes do not unite perfectly with the flattened parts of the rail heads, so that

   In the procedure described below, the fringes are removed by grinding, so that it is possible to turn the rails while maintaining their uniform structure without cracks and cracks and a uniform cross-section.

 the heat remains at which the carbon content of the steel is attacked.



   In the accompanying drawings, Fig. 1 is a plan view of the plan for abrading the

 Pulleys h set in rotation by belt g. The base plate is brought into the desired inclination by a screw spindle o and fixed by the nuts of a screw p that can be moved around a pivot pin. The frame k is brought into the desired position by the handwheel n of the screw spindle m, and the shaft f can also be set even more precisely by means of adjustable screws i.



     @ nte) Under certain circumstances, one grinding wheel may be sufficient: in general, however, it is more appropriate to arrange two such wheels so that the first is approximately up to
