Abstract: 186,949. Gore, T. April 11, 1921. Drawing wire.-The drawing and forwarding drums of a continuous wire-drawing machine consist of a main portion surrounded by a floating annulus in frictional engagement therewith so that variation of the tension of the wire does not vary the frictional relationship between the drum and the annulus, whereby the annulus is capable of movement in either direction relatively to the drum, in order to compensate automatically for differences between the normal surface speed of the annulus and the speed of the wire so that slipping occurs between the drum and the annulus and scoring of drums and roughening of the wire is thus avoided. The drums 2 each consist of two halves 7, 8 keyed to and secured by a nut 9 to its driving shaft 3 and shaped so as to provide a V-groove in which the ring 11 is seated. The parts 7 and 8 are so shaped that on adjusting the nut 9 such a degree of friction is obtained between the ring and these parts that variation of the tension of the wire does not vary this frictional relationship. The shafts of the drums are shown in Fig. 1 as being connected by reduction gearing 4 and bevel gearing 5 to a motor 6.
