the tab decelerator link which will give the desired
deceleration (Figure 13).
Carriage Return
The carriage return mechanism has been modified
to be compatible with the decimal tab mechanism
(Figure 14). Instead of the decelerator and centrifugal
governor, an air cylinder is used to cushion the shock
of the carriage return. Clutch unlatching motion is
transferred from the margin control bellcrank to the
air cylinder bellcrank to which the clutch unlatching
link is attached. A carriage return tab interlock has
been designed which is operated by the left end of the
tab lever to unlatch the clutch. A carriage return-
backspace interlock is incorporated with the back-
space bell crank. This extension of the backspace
bellcrank operates the clutch latch bellcrank to un-
latch the clutch during backspace.
Adjustments
Only those adjustments which are different from the
Model Cl will be discussed here. Refer to the carriage
return section of the Model Cl reference manual for
all other carriage return adjustments.
