Cappotto, Syracuse, NY.
  • the ribbon can break or become frayed along its heatsealed top edge and break later. Using eight yards of ribbon instead of the maximum capacity of ten yards to decrease the pressure in the storage chamber does not eliminate clogging completely.
  • Another object of the invention is to provide a stuffed ribbon cartridge for a ribbon in accordance with the foregoing object in which the ribbonwill not break.
  • Another object of the invention is to provide a stuffed ribbon cartridge for a ribbon in accordance with the foregoing objects in which the ribbon will not fray.
  • Another object of the invention is to provide a stuffed ribbon cartridge for a ribbon in accordance with the foregoing objects capable of using all kinds of ribbons such as ribbons having widely varying coefficients of friction, widely varying kinds and amounts of ink, and widely varying kinds and qualities of material.
  • Another object of the invention is to provide a stuffed ribbon cartridge for a ribbon in accordance with the foregoing objects capable of storing a maximum length of the ribbon.
  • Another object of the invention is to provide a stuffed ribbon cartridge for a ribbon in accordance with the foregoing objects in which a single strand of the ribbon will always exit from the storage chamber with very little disturbance of other portions of the rib bon in the storage chamber.
  • Another object of the invention is to provide a stuffed ribbon cartridge for a ribbon having an exit shroud in accordance with the foregoing objects in which a single strand of the ribbon will always exit from the storage chamber substantially radial to or at right angles to the shroud.
  • a shroud is positioned near the exit area of the cartridge.
  • the shroud is a ridge on the floor of the storage chamber. The distance from the top of the shroud to the ceiling of the storage chamber is less than the width of the ribbon so that only one strand of the ribbon will be withdrawn from the storage chamber at a time.
  • the shroud is formed around the exit roller in an are shaped so that the single strand of ribbon being withdrawn from the storage'chamber will cross the shroud substantially at right angles to the shroud from any direction that it is pulled from inside the storage chamber so that none of the ribbon remaining in the storage chamber will be greatly disturbed. Convolutions of ribbon in the storage chamber remain poised in an are around the shroud. Stuffed ribbon cartridges incorporating the invention have used ribbons with high coefficients of friction and the maximum length of ten yards of ribbon without clogging the exit areas and without fraying.
  • FIG. 1 is a perspective view, partially broken away, of a stuffed ribbon cartridge embodying the invention.
  • FIG. 2 is a detail view of the cartridge of FIG. 1 with the ribbon extended around the exit roller.
  • FIG. 3 is a section view taken substantially along with line 3 3 in FIG. 2.
  • FIG. 4 is a section view taken substantially along the line 4 4 in FIG. 2.
  • the invention is shown embodied in a stuffed ribbon cartridge for a machine such as a typewriter.
  • the typewriter is not shown except for part of a cartridge support 10 and part of a feed mechanism 12.
  • the feed mechanism I2 has a gear 14 for interaction with the cartridge as hereinafter described.
  • the cartridge is of the type disclosed in the copending US. Pat. application Ser. No. 288,830 of Samuel D. Cappotto et al., filed Sept. 13, 1972.
  • the cartridge has an arm 16 for guiding an endless loop of ribbon 18 toward a print point, which is not shown, of the typewriter.
  • the arm 16 is connected to a housing 20.
  • the housing 20 includes a base 22 and a cover 24 connected to the base 22.
  • a platform 26 is mounted on the base 22 to provide a storage chamber, indicated generally at 28, for the ribbon 18.
  • the platform 26 has a wall 30 and 32 around most of its periphery to confine the ribbon 18 in the storage chamber 28.
  • the inner surface of the platform 26 serves as a floor 34 for the storage chamber 28, and the inner surface of the top of the cover 24 serves as a ceiling 36.
  • the distance between the floor 34 and the ceiling 36 is only slightly greater than the width of the ribbon 18.
  • the housing 20 also has an entrance area, indicated generally at 38, and an exit area, indicated generally at 40.
  • the entrance area 38 has a knurled feed roller 42 and an integral gear 44 rotatably mounted on the housing 20 with the gear 44 in mesh with the gear 14 of the feed mechanism 12 of the typewriter when the cartridge is in operating position on the support 10 on the typewriter.
  • a knurled idler roller 46 is rotatably mounted on a bell crank 48 that is pivotally mounted on the housing 20.
  • the idler roller 46 is biased in a counterclockwise direction against the feed roller 42 by a spring lever 50 on the bell crank 48.
  • the idler roller 46 squeezes a strand 18a of the ribbon l8 entering the storage chamber 28 from the arm 16 against the feed roller 42.
  • the exit area 40 has a barrel-shaped exit roller 52 rotatably mounted on a vertical pin 54 on the floor 34 of the platform 26. As shown in FIG. 2, the roller 52 is used to change the direction of a strand 18b of the ribbon 18 being withdrawn from the storage chamber 28. After passing the roller 52, the strand 18b of ribbon 18 traverses an exit ramp, indicated generally at 56, on its way to the arm 16. Projections 58 are formed along the sides of the exit ramp 56 to guide the exiting strand 18b of ribbon 18.
  • a shroud 60 is formed around the exit roller 52.
  • the shroud 60 is a ridge on the floor 34 of the storage chamber 28. As shown in FIGS 3 and 4, the distance from the top of the shroud 60 to the ceiling 36 of the storage chamber 28 is less than the width of the ribbon 18.
  • the height of the storage chamber 28 is 035510.010 inch
  • the height of the shroud 60 is 007010.005 inch
  • the width of the ribbon l8 varies from 0.305 to 0.320 inch.
  • the distance (0.365 0.065 0.300 inch) from the top of the shroud 60 to the ceiling 36 of the storage chamber 28 is 0.005 inch less than the minimum width of the ribbon 18.
  • the shroud 60 also has an inclined surface 62 sloping toward the storage chamber 28 at a 20 angle.
  • the angle also is only an example. However, if the angle of the inclined surface 62 is too gradual, the shroud 60 has to be very wide and thus will take up too much space from the storage chamber 28. If the angle is too steep, convolutions of ribbon 18 in the storage chamber 28 will be too tightly packed around the shroud 60. It is best to have a moderate angle so that each convolution of ribbon 18 will find its own level on the shroud 60 and not all of them will be at the same level. As shown in F168.
  • the shroud 60 is formed around the exit roller 52 in an arc shaped so that the strand 18b of ribbon 18 being withdrawn from the storage chamber 28 will cross the shroud 60 substantially radial to or at right angles to the shroud 60 no matter what direction it is pulled from inside the storage chamber 28 so that none of the ribbon 18 remaining in the storage chamber 28 will be greatly disturbed.
  • the gear 44 of the feed roller 42 is in mesh with the gear 14 of the feed mechansim 12 of the typewriter as shown in FIG. 1.
  • the feed roller 42 pulls the strand 18a of ribbon 18 one character width from the arm 16 and stuffs the strand 18a, of ribbon 18 into the storage chamber 28 of the housing 20.
  • the strand 18a of ribbon 18 forms the convolutions of ribbon 18 in the storage chamber 28.
  • the convolutions of ribbon 18 form an arcuate front with the crest of the are pointing toward the exit area 40.
  • the strand 18b of ribbon 18 is being pulled from the storage chamber 28 to the arm 16 at the exit area 40.
  • the strand 18b of ribbon 18 is pulled across the shroud substantially radial to or at right angles to the shroud 60 no matter what direction it is pulled from inside the storage chamber 28. Since the strand 18b of ribbon 18 crosses the shroud 60 substantially at right angles to the shroud 60, the convolutions of ribbon 18 remaining in the storage chamber 28 are only slightly disturbed by the withdrawal of the strand 18b of ribbon 18. ln crossing the shroud 60, the strand 18b of ribbon 18 might collapse to conform to the cross section of the shroud 60 as shown in FIG.
  • An improved stuffed ribbon cartridge for a ribbon having a storage chamber for the ribbon with a floor and a ceiling substantially perpendicular to and farther apart than the width of the ribbon and an exit area for a single strand of the ribbon to exit from the storage chamber, wherein the improvement comprises a shroud on the floor of the storage chamber near the exit area and an inclined surface on the shroud rising from the floor toward the exit area until the distance from the top of the shroud to the ceiling of the storage chamber is slightly less than the width of the ribbon to restrain all but the single strand of ribbon from being fed from the storage chamber.
  • exit area includes a roller to change the direction of the single strand of ribbon exiting from the storage chamber and the shroud is formed around the roller.
  • An improved stuffed ribbon cartridge for a ribbon having a storage chamber for the ribbon and an exit area for a single strand of the ribbon to exit from the storage chamber, wherein the improvement comprises a shroud formed in an are near the exit area for confining the width of the ribbon to a space less than the width of the ribbon to restrain all but the single strand of ribbon from being fed from the storage chamher.
  • the storage chamber has two substantially parallel surfaces greater than a ribbons width apart to confine the ribbon in the storage chamber with the width of the ribbon substantially perpendicular to the surfaces, and the shroud is a ridge on one of the surfaces with the distance from the top of the ridge to the other surface less than the 6 width of the ribbon.
  • exit area includes a roller to change the direction of the single strand of ribbon exiting from the storage chamber and the shroud is formed around the roller.
