As the latter moves up and down the pins play upon the under side of the lower arm of the rocking-lever, thus canting it and pushing the type-wheels to the right or left, as the case may be.
This is accomplished through the movements of a three-arm rocking-lever attached to the wheel-sleeve at the end of the shaft.
As the arm lifts upward, the pin moves along the under side of the lower arm of the rocking-lever, thus causing it to cant and shift the type-wheels to the right or left, as desired.
Meanwhile the type-wheels are rotating, carrying with them the rocking-lever, and current is pulsating over both circuits.
When the type-wheels have arrived at the proper point the rocking-lever has been carried to a position where its lower arm is directly over one of the pins on the arm extending from the platen of the press-lever.
