movement is made before going any further. Still keeping
our attention on the D key, let us follow its direction.
“ The key is attached to a steel lever which passes through
a slotted comb, then through the body of the machine, and
finally out at the rear portion, where it terminates in a
kind of hook, technically called a toe, resting on a metal
rod, which latter serves as its fulcrum. Attached to this
metal rod, but inside the body of the machine, and therefore
out of sight, will be seen, on looking closely, two oscillating
shafts, and if we again touch a key we notice that it causes
one of these shafts to move downward. Each lever affects
this shaft in a greater or lesser degree, and since the shaft
causes the cogged arm named above to rock, it follows that
the extent of the movement of the typewheel depends upon
the extent of the movement of the shaft.
