THE YOKES of the right and left pin wheel assembly
straddle the knife and holder assembly thereby assuring
that a protruding pin will always be adjacent to the knife
and holder assembly in its rotation about the platen, and
at the same time keep the form in its original registration.
THE LIFTER STOP STUD is located just below and to the
rear of the tab rack on the carriage side frame. Its function
is to limit the upward travel of the platen so that the
upper arm will not travel past its toggle point (Figure 2).

THE RIGHT AND LEFT SPRING ARM AND LATCH
ASSEMBLIES latch the knife and holder assembly in its
normal position. When the platen is raised and the spring
latch arms are released, the knife and holder assembly
will drop away from the platen, allowing the form
to
be
inserted easily from the rear of the machine.
THE LINE GAGE HOLDERS have been relieved to prevent
the pins from striking them. (Figure 3).
