    Abstract: A cyclically operable high speed data printer comprising a plurality of type wheels supported and yieldably driven by a drive shaft, each wheel having character position stops and a home stop. The drive shaft is driven through two revolutions in the same direction for each cycle. During the first revolution, stop devices are spring actuated at different times to engage certain of the character position stops to arrest the type wheels in different type printing positions. Printing occurs after the first revolution, and during the second revolution, the stop devices are positioned to arrest the home stops whereby to locate the wheels in their home positions.

    Abstract: A pin carriage for adding and calculating machines embodying settable escapement pins for stepping the carriage, the pins each having a camming edge which cams the carriage in a retrograde direction upon movement of the pin from a carriage-arresting position, in engagement with an arresting element, to a nonarresting position. This produces a detenting action of the pin which is in arresting location without requiring the usual individual pin detents.
