ABSTRACT:
Wire drawing apparatus for ease in manually drawing precious metal wire is formed by an elongated base having a forward end portion transversely supporting a draw plate through which wire stock may be drawn and a downturned rearward end portion having a pivotally connected upstanding lever moveable at its upper end portion toward and away from the draw plate by pivoting about a horizontal axis. A wire grip for grasping wire dawn trough the draw plate is attached to the lever by a link chain extending through a keyhole slot in the depending end portion of the lever for edgewise nesting one link of the chain prior to manually moving the lever in a direction opposite the draw plate.
