DEFINITION

Classification: 408/181

(under subclass 153) Device in which the displacement of the tool is caused by a member having a helically-ribbed surface rotatable relative to a cooperating surface so that the ribbed surface and the cooperating surface are relatively displaced along the axis about which the helically-ribbed surface rotates; whereby, a tool connected to one of the surfaces is displaced; wherein, the member having a helically-ribbed surface is rotatable about an axis that intersects and is normal to the tool-axis.
