Definitions

  • rlFhis invention relates to new and useful improvements in manifolding devices which may be readily attached to any standard typewriting machine without changing such machine in any material respect, and embodies certain improvements over the,con struction disclosed in the co-pendng application of Gustave O. Degener, Serial No. 491,558,51ed Oct.. 27, 1930.
  • the invention like that of the invent-ion of the Degener application is designed for the purpose of writing on continuous forms of work sheets which are frequent- 1y in lengths of several hundredfeet.
  • the invention includes a carriage having a non-rotatable platen past whichwork sheets are fed, and a collating frame which supports the platen and is mounted on the carriage to swing forwardly and rearwardly, thereby moving the platen rearwardly to relieve the normal tight contact relation between the platen and the work sheets, and forwardly to resume said tight contact relation.
  • a plurality of carbon strips or ribbons extend in front of the platen and in interleaved relation with the work sheets, and these strips are fed from individual spools which are rotatably mounted directly on the main frame of the machine. These strips are fed by a feeding means located at one side of the carriage, and onv the other side of the carriage between the spools and th platen, these strips pass through a tensioning means which is giadually increased' during the feeding movement f the strips.
  • Mounted on the collating frame is a line spacing mechanism for the work sheets and a driving connection between the collating frame and the strip feeding means Jis provided.
