 durch die Spiralfeder 20 in um   180"umgedrehter   Lage wieder zu der Schleifwalze 1 anliegend angezogen. Nun behält es diese Lage, solange der Daumen   2-J   bei der Weiterdrehung der Kurbel 15 frei bleibt (Fig. 1), welches Spiel sich bei jeder folgenden Umdrehung der Kurbel wiederholt. 



  Damit die   Schleifrolle 1   nicht verkehrt gedreht werden kann, ist die Kurbel 15 mittelst einer Hülse   15á   auf der Wellenverlängerung 14 lose aufgesteckt und schlägt bei richtiger Drehungsrichtung gegen einen auf dem Daumen 12 befestigten Mitnehmer 16 an, welcher aus einem konzentrischen Blechstreifen von der Gestalt eines rechtwinkligen Dreieckes o. ä. besteht, dessen Hypothenuse ein Stück Schraubenlinie darstellt. Will man die Kurbel verkehrt umdrehen, so gleitet sie auf dieser Schraubenlinie in der Richtung der Achse heraus, ohne die Schleifrolle mitzunehmen, indem die Rollenreibung bedeutend grösser ist als die Kurbelreibung.

 EMI2.1
 by the helical spring 20 in a position turned 180 "back against the grinding roller 1. It now retains this position as long as the thumb 2-J remains free as the crank 15 continues to turn (FIG. 1), which play occurs with each subsequent Rotation of the crank repeated.



  So that the grinding roller 1 cannot be rotated the wrong way round, the crank 15 is loosely attached to the shaft extension 14 by means of a sleeve 15á and, when the direction of rotation is correct, strikes against a driver 16 attached to the thumb 12, which consists of a concentric sheet metal strip of the shape of a right-angled There is a triangle or the like, the hypotenuse of which represents a piece of helix. If you want to turn the crank the wrong way round, it slides out on this helical line in the direction of the axis without taking the grinding roller with it, as the roller friction is significantly greater than the crank friction.
