In the case of large cables only the metal is preferably heated for the eighth, ninth, and tenth operations.

I will now refer to the figures which illustrate the series of tools whereby the above mentioned operations are performed.

Fig. 1_a_ shows a plan (the punch being in section) and Fig. 1_b_ an elevation of the bed die of the tool by which the notches b of the first operation are performed.  The feed mechanism is not shown, but might be of any ordinary intermittent kind. g is a groove in the bed, in which lies the lower vertical web of the rod, of cruciform section, the two horizontal webs lying upon the bed with the edge of the web to be notched lying just over the die, in which works the punch, B, of which B’ is the cutting edge.  The punch is operated in the usual way, its lower end, which does not rise out of the die, acting as a guide.  B* is the beveled stop in the groove, g, which by fitting in the notches, b or b’, corrects inaccuracies of the feed.

Fig. 2_a_ is a sectional plan and Fig. 2_b_ an elevation of the tool by which the second operation is performed, the same tool being also used for performing the third operation. (Illustrated in Fig. 3_a_.) h h are a pair of bed-dies having a space h’ between them to receive the lower web of the bar, and having notches, C C and D D, in their inner ends, forming counterparts of the punches by which the pairs of mortises, c d, Fig. 2, are punched in the pair of webs lying upon the bed-dies, h.  These bed-dies are fitted to slide a little in opposite directions upon a suitable bed plate and are caused by the inclined cams, i’, on the guides, i, of the press head (which pass through corresponding apertures in the bed-dies, h) to approach each other at the moment the punches come down on the work, so as to grip the lower web of the rod and support the pair of webs being operated on close up to the sides of the lower web lying in the space h’, while when the punches rise the bed-dies move apart, so that the web is quite free in said space h’ and the rod may be easily fed forward for a fresh stroke of the press.  B* is the beveled stop in the space, k’, as in the tool first described.  The bed-dies h have a second set of notches C’ D’ at their outer ends, similar to but longer than those C D, so that by reversing the bed-dies they will form counterparts for a second set of punches corresponding thereto for performing the third operation—­i.e., enlarging the mortises, c d, as represented in Figs. 3 and 3_a_; or, instead of adapting the dies, h, to perform the two operations, separate tools may be used for the second and third operations.
