FIG. 3a.
Fig. 4a is an elevation and Fig. 4b a sectional plan of the tool for performing the fourth operation—namely, removing the portion a*, Figs. 3, 3a, 4a, and 4b. This is done by a pair of punches, A*, corresponding in shape to the ends of the link in the rough and to the aperture shown in the bed-die, k, Fig. 4b, which has a groove, k', to admit the lower web of and to guide the rod. The beveled stop, B*, used in operating on the pair of webs, a, corresponds to the notches, b'; but in operating on the webs, a', the stop must be replaced by one corresponding to the aperture left by the removal of the portion, a*.
Fig. 5a is an elevation, Fig. 5b a plan, and Fig. 5c a longitudinal vertical section of the tool for performing the fifth operation, the work being shown in section in the latter figure. It consists of a bed-die, l, with groove, m, to receive the lower web, but terminating at a distance from the die apertures, so as to leave supports, n, for the parts, e*, of the rod to resist the downward pressure of the punches, E, which remove the portions, e, from each side of the cross stay, as shown in Figs. 5b and 5c. The correct position of the work in regard to the punches is insured by these supporting parts, n, which terminate the grooves, m.
