an article being manufactured.
In the manufacture of shoes by the so-called
rink system, a plurality of machines are arranged
in series in the order of operations which are to
10 be performed. An operator of a preceding ma~
chine, for example operator number 1, as fast
as he completes his operation on a shoe, places
the shoe upon a support which is accessible to
operator number 2 of the succeeding machine.
15 Operator number 2 takes the shoes one by one
from this support, operates upon them and places
them upon a. second support which is accessible

These and other features of the invention, in
eluding certain details of construction and com

in an illustrated construction and pointed out
