Abstract
564,010. Making nuts. DAUBIGNY, R. F., and MINCHIN, A. E. May 20, 1943, No. 8054. [Classes 83 (ii) and 83 (iv)] Parts of lock nuts, such as are described in Specification 502,477, are forged from bar stock h, Fig. 5, in 'dies f, g in a machine that presses the bar against the end i of the inner die. Current is then passed between the dies and the bars to raise the end of the latter to forging temperature, at which stage the pressure on the bar advances. it to fill the cavity between the dies, the current being cut off. The die parts are then moved relatively to expose the part of the bar when cut off is to be effected as by a sawing adjunct. The inner part is produced in a similar manner, the tapping and splitting being effected subsequently. In the case of small nuts, a number of bars are forged simultaneously.
