Abstract

1,181,050. Heating tubing by passage of current. CALUMET & HECLA CORP. 23 Dec., 1968 [19 Feb., 1968], No. 61008/68. Heading H5H. [Also in Division C6] Tubes are annealed by passage between a pair of electrical contact wheels 14 and 16, a pair of guide wheels 10 and 12 being positioned to cause the advancing tubing to be bent around both contact wheels so as to have extended contact therewith. The contact wheels, at least one of which has its peripheral portion formed of spark suppressing material, are supplied with current so as to heat the portion of tubing therebetween and the tubing is continuously advanced by rotating the wheels. As shown in Fig. 2, a contact wheel comprises a metal wheel 38 attached to a flange 40 on driving shaft 32. A contact ring 44, having a peripheral groove 46 to carry the tubing, is attached to wheel 38 by means of mounting ring 48, the other side of the wheel having a support ring 54. Heat is dissipated from the contact wheel by a water spray from nozzle 58, the water being prevented from reaching the groove 46 by a dished guide plate 60 screwed to the wheel. Current may be supplied to the wheel through the shaft 32 or through contact brushes 62 urged against mounting ring 48 by compression spring 64 the thrust of the brushes being balanced by diametrically opposite rollers 72.
