ABSTRACT:
A drawing-in dog for a wire drawing machine has gripping surfaces formed on two opposed wedge members. Both wedge members are slideably mounted in a housing which tapers towards the aperture through which the wire is to be inserted. One wedge member is coupled by a toggle link to a lever pivoted on the housing, whereby the wedge member may be moved between a released position and a position where it is urged by the lever and toggle link into positive gripping engagement with the wire. The other wedge member is freely slideable so as to enable the dog to accommodate wire of a range of diameters.
