of the link in the
rough and to the aperture shown in the bed-die, _k_, Fig. 4_b_, 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. 5_a_ is an elevation, Fig. 5_b_ a plan, and Fig. 5_c_ 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. 5_b_ and 5_c_. The
correct position of the work in regard to the punches is insured by
these supporting parts, _n_, which terminate the grooves, _m_.

Fig. 6_a_ is an elevation of the winch for performing the sixth
operation.

Fig. 7_a_ is an elevation and Fig. 7_b_ a plan of the tool for
performing the seventh operation. P P are the punches for trimming the
outside and Q Q those for trimming the inside of the ends of the
links. The links adjacent to the one to be operated on are brought
together into the position shown in dotted lines, the bed-die having
an aperture in it to admit of this, so that both ends of the link to
be trimmed may be operated on together.

The tool for performing the eighth operation consists of a pair of
swages, the bottom one only being shown in Fig. 8_a_. The swages
correspond to the intended rounded sectional form of the ends of the
link, which is placed in position between the swages in a similar
manner to that described for Fig. 7_b_, so that both ends are rounded
or finished off at once.

Fig. 9_a_ is a plan of the bottom swage of the tool for performing the
ninth operation, the upper swage corresponding thereto at least in so
far as the middle part of the link to be operated on is concerned.

The tool for performing the tenth operation is represented in
elevation and plan in Figs. 10_a_ and 10_b_. It consists of a pair of
bed-dies, R, fitted to slide together and operated by the cams, s, on
the guide rods, S, the operation being similar to that of the tool
shown in Figs. 2_a_ and 2
