From this point onwards care must be borne, \ i \ 'as in turn causes a corresponding accuracy and thus sweeping costs in the production *

It has been shown that, with the otherwise identical design of the ballpoint pen according to the Häiptpatent, a simplification and improvement can be achieved »if, according to the invention, the guide piece to be arranged in the front part of the ballpoint pen is secured against axial displacement, but freely rotatable on the lower face with grooves, recesses formed o _e the like, and provided .Axialnocken necks is "this means that this F-'iirungsst ^ ck, which ine in the locking of the L'st write latching causes RECOVERY, on assembly of the liigel recorder or" upon insertion of which it automatically adjusts itself to the correct position in the direction of rotation, this adjustment is particularly facilitated when the axial cams of the sleeve on both sides of a flat surface are in alignment with the
