Definitions

  • This invention relates to an inking ribbon cartridge for a typing or printing device comprising a case having a flat base and an inked ribbon in the form of an endless belt mounted therein for transport about several parallel aligned rollers.
  • the inking ribbon has a half twist forming a Mobius 100p configuration which thereby doubles its effective length.
  • lnk deposits on the ribbon may be replenished by means of an ink pad mounted in contact with the ink ribbon.
  • the ribbon is moved by means of a drive roller which has power coupled to it from the typing or printing machine.
  • an object of this invention is to increase the rela tive lifetime of an inking ribbon by a simple and economic means.
  • Another object is to provide a more efficient and longer lasting inking ribbon for utilization in a cartridge for attachment to a typing or printing machine.
  • a ribbon cartridge was improved by placing a half twist in the ribbon between two parallel aligned rollers to form an endless belt Mobius loop configuration.
  • the effective area of utility on the ribbon surface is thereby doubled and consequently, for a given length ofink ribbon, the amount ofwear per unit of time is halved.
  • FIG. 1 is an illustration of applicant's re-inking cartridge, including a ribbon with a Mobius loop;
  • FIG. 1a is a magnified view of the half twist in the ribbon of FIG. 1;
  • FIG. 2 is a sectional view of the tension roller construction taken along line 22 of FIG. 1.
  • applicant's ribbon cartridge includes a housing, preferably of plastic material, having a flat base portion 13 and an upwardly extending sidewall 15.
  • the shape of the housing is such that it has an elongated middle portion 3 with two substantially parallel end portions 5 and 7 protruding therefrom substantially perpendicular to the middle portion and integral therewith.
  • Opposing slits l7 and 19 are formed in sidewall at the end portions 5 and 7 of the housing for permitting an ink ribbon 21 to pass outside the cartridge, through a printing area 20, and back into the cartridge housing along a single longitudinal axis, thereby obviating the need for any rib bon transport rollers outside the cartridge.
  • a plurality of transport rollers 25, 27, 29 and 31 which may be of plastic material, are rotatably mounted on base 13 for spacing and transporting ink ribbon 21 in a path parallel to base 13. Each roller is mounted with its rotational axis perpendicular to base 13.
  • a drive roller 33 having a keyed slot 35 therethrough is mounted over an aperture (not shown) in the cartridge base 13.
  • a male interposer (not shown) is inserted through the base aperture and engages the keyed slot 35 in the drive roller 33. The interposer conveys rotating motion from a power source (not shown) in a typing or other printing machine to the drive roller 33 for moving ink ribbon 21.
  • An inking pad 37 is rotatably mounted in the cartridge with perpendicular to base 13, as known in the art. As ink ribbon 2 moves past and in tangential contact with the pad 37, a layer of ink is deposited on the ink ribbon 21. Any excess ink deposited on the ribbon 21 is scraped away, as ribbon 21 moves past and in contact with wedge 23, which may be integral with the plastic housing.
  • a tension roller 39 is provided in a known manner, to insure that ink ribbon 21 is always maintained in proper tension as it wears, or changes length because of changes in environmental conditions.
  • a support block 41 with a horizontal hole 43 therethrough is rigidly attached to base 13.
  • a rod 45 is slidably inserted through hole 43 at one end and connected to a bifurcated mount 47 at the other end.
  • a helical compression spring 49 mounted around rod 45 biases mount 47 away from support block 41.
  • Bifurcated mount 47 has slots 51 and 53 in each arm for receiving the axial portions 55 of tension roller 39 which is biased into the closed end of an elongated bight 9.
  • the bottom portion of axle 55 extends through an oblong slot 57 in base 13 for maintaining tension roller 39 at a constant angular disposition with respect to support block 41.
  • ribbon 21 is formed with a half twist thereby establishing a topological configuration in the ribbon 21 which is usually designated as a Mobius loop.
  • a span of ribbon 21 containing the half twist is supported across at least half the width of the cartridge between transport roller 27 and drive roller 33, and the axis about which the twist is generated extends between rollers 27 and 33 and parallel to base 13.
  • a point 59 on the top edge of ribbon 21 at roller 27 spirals to the bottom edge at roller 33.
  • the Mobius loop configuration on applicant's inking ribbon 21 is greatly simplified over the prior art which required the ribbon to be transported out of a path parallel to the cartridge base 13. With applicant's Mobius loop configuration, the endless inking ribbon 21 can be readily mounted in a flat cartridge of minimum height. The amount of room required for the inking cartridge in the printing device is reduced, and the cartridge itself can be more economically produced.
  • rollers each rotatably mounted in said cartridge and each having a rotational axis perpendicular to the base of said cartridge and an endless belt inking ribbon supported by said rollers entirely within a plane parallel to said base, a pair of said rollers being positioned for supporting a span of said ribbon across at least half the width of said cartridge, said span of ribbon containing a half twist to form a Mobius loop in said ribbon.
  • said inking ribbon cartridge improvement of claim 1 wherein said cartridge includes a sidewall defining an elongated middle portion and two substantially parallel end portions protruding from said middle portion substantially perpendicular to, and integral with, the middle portion, said sidewall having two opposed slits for passage of said ribbon through a printing area, one of said slits being located near the tip of each of said end portions, and said rollers being entirely surrounded by said sidewall.
