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_b_, except that there are no punches, and
that the link which lies in the cavity of the dies is merely
compressed in the lateral direction by the inward motion of the
bed-dies.
My invention further comprises a modification of the above described
process, which has for its object to enable the weldless stayed links
to be made as short and particularly as narrow as may be necessary in
order to adapt the chain to run over the sheaves of pulley blocks and
to suit other purposes for which short-link welded chain has
heretofore only been available.
