Definitions

  • This invention relates to apparatus for defining characters on impression-receiving material, e. g. paper.
  • apparatus comprising a platen, a plurality of styluses supported for independent axial movement towards the" platen, a reciprocating member co-operating with the marking ends of said styluses to reciprocate said marking ends lengthwise of the platen in paths which determine the max mum widths of characters to be defined by the styluses, actuating means for each stylus operable during movement of the marking end of the stylus by said reciprocating member to apply discrete impulses to the stylus to effect lengthwise movements thereof to cause its marking end to make character-defining marks on the impression-receiving material, and feeding means to feed the material between the platen and styluses with a linear speed which determines the maximum height of the characters, and the present invention is an improvement to such an apparatus.

  • webs 10, 11 of transfer media I such as a carbon ribbon or the like although it will be readily understood that, if desired, the original copy 8 may, in known manner, bear a transfer media on the reverse side thereof thus avoiding the necessity for the web 11.

  • the feeding apparatus for the web The marking ends 3 of reciprocating guide member 12, the wires passing through apertures 13, Fig. 3, in the guide member.
  • the member 12 is supported for lengthwise movement by fixed guides 14, 15, Fig. 2, and is connected by an eccentric strap 16 with an eccentric 17 rotated by any suitable means, not shown.
  • the eccentric throw is such that the amplitude of reciprocation imparted to the marking end 3 of each stylus 1 by the member 12 is equal to the maximum width of a character to be defined thereby as illustrated in Figs. 5 and 6.
  • the member 12 makes eleven reciprocations 18, Figs. 5 and 6, during the definition of a character, however as can be seen from Figs. 5 and 6 the arrangement is such that discrete impulses are applied to the wires 1 only during the first eight of a cycle of eleven reciprocations 18, the remaining three reciprocations of the cycle being idle and representing the interval during which selection is made from a plurality of continuously rotating character-determining discs 19, of which one is illustrated in Fig. 4, to control the operation of solenoids 6, and during which line spacing is effected.
  • Each character-determining disc 19 is electrically connected with each solenoid 6 and is provided with peripheral electrical contacts 19a-19cc for co-operation with brushes, not shown, so that at intervals and for periods determined by the contacts the solenoid 6 is energised and imparts discrete impulses to wire 1 causing the wire to be moved lengthwise to impinge against the web 10 so that, according to the length of a contact, a dot or a line is marked on the webs 8, 9.
  • the reference numerals 19a-19cc indicate the contacts and the dots or lines marked as a result thereof, the contact 19p resulting in the marking of a line.
  • Figs. 4 the reference numerals 19a-19cc indicate the contacts and the dots or lines marked as a result thereof, the contact 19p resulting in the marking of a line.
  • the two vertical lines indicate the end positions of the stroke of the marking end 3 of a stylus and the sloping lines indicate the approximate path traced in space by the end 3 relative to the paper webs 8, 9 due to movement thereof at a constant linear speed as aforesaid.
  • the references 360 indicate the end positions of wire end 3 in relation to the angular movement of disc 19.
  • Figs. v5 and 6 illustrate respectively the manner in which a character is simultaneously formed on an original, Fig. 5, and on a copy, Fig. 6, it being assumed that the height of characters on the copy are to be one-half that of those on the original, as indicated by the references X, Fig. 5, and
  • a stylus in the embodiment of the invention described above, has been described as flexible wires, but it will be understood that, if desired, a stylus can have a form other than that of a wire and may comprise a stylus which is provided with marking material so that it makes an impression on the web 8 by direct contact with the web thus avoiding the use of the transfer web 10. In such case, however, the transfer web 11 will be necessary unless transfer media is carried by the reverse side of web 8.
