Abstract

1491926 Writing appliances CHROMATIC CORP 4 Aug 1975 32569/75 Heading B6P Relative rotation of the clip-bearing and body parts of a pen in one direction causes one of strap-linked writing units 73 to be pushed downwards by pressure of cam 59 on the respective cam follower 46. The other writing unit is correspondingly retracted by flexible strap 42, which passes over a support at the upper end of an internal support linked to body part 12. The pen may be so arranged that rotation in one direction advances one writing unit and rotation in the other the other, with an intermediate position in which both units are retracted.
