When the operator desires

he depresses a
foot pedal 50, which, through the medium of a
link 5I interposed between the pedal and the
lever 28, raises the clamp 2l out oí engagement

ator then raises the forms out of contact with the
pins 24 and draws them forwardly. Simultane

openings 25. as the forms are drawn iorwardlyf50
This is accomplished as' shown in Figs. 1 and. 3,
