History of the Typewriter

— 146 — Some “ Blick ” Models. Fig. 115 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.
