Definitions

  • the cartridge is provided with ribbon guide means which correspond to the ribbon guide means of the writing machine whereby upon insertion of the cartridge with the ribbon into the writing machine the ribbon is transferred from the guide means in the cartridge to the guide means in the writing machine.
  • the cartridge further includes a bottom with open ended apertures for insertion into the writing machine and with releasable interlocking means whereby the empty cartridge may be removed from the writing machine.
  • the present invention relates to a ribbon Cartridge, especially for writing machines.
  • the present cartridge is suitable not only for typewriters but also for any other writing machine employing a carbon ribbon, whereby the cartridge may be used in connection with woven ribbons as well as with plastic film ribbons.
  • ribbon exchange ribbon cartridges which are suitable not only for the storage and transporting of the ribbon but which are also intended to facilitate the insertion of the ribbon into the writing machine.
  • cartridges which permanently contain the new ribbons and which remain in the writing machine until the entire ribbon has been used up whereupon the cartridge as well as the ribbon are discarded.
  • this typeof cartridge requires still a substantial skill for the insertion of the ribbon into the guide means which define its path through the writing machine.
  • the ribbon exchange always involves the drawback that not only the operators fingers but also the clothing and the entire environment of the writing machine may become soiled as a result of a ribbon exchange.
  • the cartridge shall also be removable, at least partially, preferably completely from the machine as soon as the new ribbon has been inserted in order to avoid any influence or interference of the cartridge with the proper operation of the writing machine;
  • a writing ribbon cartridge which has a cartridge housing and a ribbon guide path between a ribbon supply roll and a ribbon take-up roll which guide path corresponds substantially to the path of ribbon travel through the writing machine.
  • the housing of the cartridge has a cover member and a bottom which are removable from the writing machine just as soon as a new ribbon has been inserted into the machine.
  • the cartridge bottom comprises a plurality of open ended apertures separated by finger shaped portions of the cartridge bottom which fit or engage respective slots in a side wall of the cartridge cover member so that by withdrawing the fingers from said slots the bottom of the cover member may be removed separately from the writing machine.
  • FIG. 1 is a top plan view of a cartridge according to the invention made of transparent plastic material
  • FIG. 2 is a side view of the cartridge according to FIG. 1 as seen in the direction of the arrow B in FIG. 1, however, with the top of the cartridge facing downwardly;
  • FIG. 3 is a side view of the cartridge according to FIG. 1 as seen in the direction of the arrow A in FIG. 1, with the top of the cartridge facing upwardly;
  • FIG. 4 is a top plan view of the cartridge bottom
  • the present cartridge comprises a housing 1 including a cover member 2 and a bottom member 3 best seen in FIG. 4.
  • a first bobbin 4 supported on a journal pin 5 carries a roll 6 of unused ribbon 7.
  • the supply roll 6 is rotatable counter-clockwise as indicated by the arrow 8 to pay out the ribbon 7 through a pay out ribbon slot 9 in a side wall of the cover member 2.
  • the ribbon 7 emerges from the slot 9 and is guided along the outer surface of the side wall to a guide pin 10 arranged in a corner of the somewhat V-shaped side wall 11 of the cover member 2 whereby a guide slot is provided between the surface of the side wall 11 and the pin 10.
  • the just mentioned guide slot is open at its upper end.
  • the ribbon 7 then continues to be guided along the outer surface of the side wall 11 of the cover member 2 until it reaches an infeed slot 12 in the side wall 11.
  • guide means in the form of guide pins 13, 14, 15, 16, and 17.
  • These guide pins l3, l4, l5, l6 and 17 are arranged according to the invention in such positions as to substantially duplicate the path of the ribbon 7 through the writing machine, whereby such path is defined by guide means (not shown) located in the writing machine.
  • These guide pins 13 to 17 guide the ribbon 7 inside the cartridge toward a second bobbin 18 supported on a journal pin 19 where the used ribbon 7 is taken up to form a roll 20 which rotates clockwise as indicated by the arrow 21.
  • the supply bobbin 4 and the take-up bobbin 18 need not necessarily be arranged on journal shafts or'studs which are re ceived in respective recesses in the writing machine, but that the bobbins 4 and 18 may be hollow for receiving respective journal studs located in the writing machine.
  • the guide pins l3, 14, 15, 16 and 17 are attached to the cover member 2. These guide pins 13, 14, 15, 16 and 17 may be located so that the respective guide means in the writing machine will be positioned in parallel to the guide pins 13, l4, 15, 16 and 17 of the cartridge for transferring the ribbon 7 from the guide pins 13, 14, l5, l6 and 17 of the cartridge to the guide means of the writing machine when the cartridge is removed after insertion of the ribbon 7.
  • the guide pins 13 to 17 may also comprise tubular members into which respective ribbon receiving guide means of the writing machine may fit for receiving the ribbon 7 upon removal of the cartridge.
  • FIG. 2 illustrates a view in the direction of the arrow B shown in FIG. 1 whereby the top wall 22 of the cover member 2 faces downwardly.
  • the cover member 2 comprises slots 23 along its bottom edge 24. These slots 23 provide releasable engagement means for the cartridge bottom 3 to be described in more detail below.
  • the cover member 2 may further comprise reinforced edges 25. Incidentally, the cover member 2 may have portions of different heights, interconnected by a preferably slanting top wall member 36.
  • FIG. 3 illustrates a view of the cover member 2 in the direction of arrow A as shown in FIG. 1.
  • This view illustrates the other longitudinal wall 26 of the cover member 2 which may, for example, be provided with a cut out 27 to enable grasping of the cover member 2, to facilitate the removal of the cartridge from a writing machine.
  • the lower edges 25 of the shorter side walls may be provided with inwardly facing grooves 28 and 29 which may receive the lateral edges of the bottom 3. These grooves 28 and 29 may cooperate with the slots 23 and the bottom member 3 for forming releasable engagement means between the cover member 2 and the bottom member 3.
  • the grooves 28 and 29 may be provided without the addition of the slots 23.
  • FIG. 4 illustrates a top view of the bottom member 3 which comprises a plurality of fingers 30 forming a somewhat comb-shaped configuration since the fingers 30 are spaced by apertures 31 which are preferably open ended to facilitate the insertion and withdrawal of the cartridge relative to the writing machine.
  • the finger tips 32 fit into the slots 23 as described above.
  • the lateral edges 33 and 34 of the bottom member 3 fit into the grooves 28 and 29 also as described above.
  • the bottom member 3 may be provided with a handle 35 extending along its rear edge for facilitating the insertion and/or removal of the bottom member 3 from the cover member 2 of the cartridge.
  • FIG. illustrates a rear view of the bottom member 3 showing specifically the handle 35.
  • the position of the handle 35 is not critical and could be located in any other position convenient for the insertion or withdrawal of the bottom member 3 from the cover member 2.
