During the travel of the chains 68 in the lower
night, the plungers 1| are maintained in re
tracted (open) position due to rails which coop
erate with the top rollers 13. When the chains
pass around the sprockets 66, the rollers 13 en
gage a horse-shoe-shaped cam 90 which causes
the plungers to move inward so that when the
rollers 13 leave thehorse-shoe cam 00, the grip

A camming surface positioned longitudinally of
the machine rcooperates with each roller- 13 to
maintain the plungers l1| in position `during the
gripping action of the gripping elements. For
preventing lateral displacement of the block as
it passes around the sprockets 66, each block is
provided with a pair of shoes 92 which cooperates
with an arcuate cam (not shown). As shownfin
