Definitions

  • a spoolless ribbon cartridge containing either an endless fabric ribbon or a roll of single-pass carbon ribbon and having projecting members which hold a portion of ribbon accessible for printing.
  • the cartridge has built-in rotatable drive members for forcing used ribbon into a chamber of the cartridge where it is stored in random, multi-folded fashion.
  • the drive members are rotated under control of a ribbon lift mechanism, which positions the cartridge such that printing occurs alternately from the upper and lower halves of the ribbon. Such rotation mayeffect a half character movement of the ribbon in each printing cycle or a full character movement of the ribbon in every other print cycle, depending on the design.
  • This invention relates to a ribbon mechanism for an office machine, such'as a typewriter, and more particularly, to a ribbon cartridge and a lift and feed mechanism therefor.
  • Ribbon cartridges are known (from US. Pat. Nos. 2,902,136, 3,008,561, 3,151,724 3,260,344, and 3,356,202, for example), but these all have disadvantages-Most have a multiplicity of parts such as supply and take-up spools, and drive means for both.
  • cartridge insertion in the machine requires careful location and a steady hand to pass the ribbon between the forks of the usual ribbon vibrator, or worse, requires manual stripping of a portion of the ribbon for such purposes, thus involving messy contact between the ribbonand the operators hands.
  • the load on the ribbon tends to increase to the point of breakage, again involving a handling of the ribbon with consequent soiling of the operators hands.
  • the present invention solves the above-mentioned problems by providing a ribbon cartridge which is very simple'in structure because it obviates the need for supply and take-up spools and their interrelated drives; eliminates need for a separate, variably positionable ribbon support mechanism; and incorporates a ribbon feed which stores the ribbon in the cartridge in random folds and may precrease it for more compact storage.
  • the cartridge may contain inked ribbon, carbon ribbon, or the like and is readily interchangeable with similar cartridges.
  • Spool herein refers to a flanged ribbon bobbin.
  • FIG. 1 is a perspective view of a fabric ribbon car tridge according to a first embodiment of the invention, including a lift and feed mechanism;
  • FIG. 2a is an enlarged perspective view of the ribbon feed entrance of the cartridge of FIG. 1, showing the ribbon disposed between dual feed gears with oscillating packing fingers for moving the entered ribbon away from the feed gears, while FIG. 2b is a plan view of same including a feed ratchet, pawl and detent;
  • FIG. 3 is a perspective view of a carbon ribbon cartridge according to a second embodiment of the invention, again including a lift and feed mechanism;
  • FIG. 4 is an enlarged perspective view of the ribbon supply exit of the cartridges of FIG. 1 or FIG. 3, showing the integral ribbon guides within the cartridge housing.
  • FIGS. 1 through 4 show the typewriter ribbon supply and its lift and feed mechanism as particularly applied to a printing machine such as a typewriter having a single multi-character print element 42 movable laterally over the surface ofa record medium 14 supported on a laterally fixed platen 15, although the concept is equally applicable to typewriters having a laterally movable document carriage and multiple typebars.
  • a fabric ribbon cartridge 1 in FIG. 1 is a first embodiment of the invention, and a carbon ribbon cartridge 61 in FIG.
  • Cartridges 1 and 61 are each pivotable about pivot studs 4, 5 fixed to vertical side flanges 2b, 2a of support bracket 3.
  • the studs 4, 5 enter notches 9 or 109 (only one shown in FIG.
  • each cartridge 1, 61 is formed in the sidewall 6 or 106 of each cartridge 1, 61 for purposes of ready insertion and removal by a simple drop-in/lift-out technique and for locating the ribbon 8 or 66 with respect to the platen 15.
  • a latch (not shown) may lock the cartridge 1 or 61 down.
  • Fabric ribbon cartridge 1 is in the form of a roughly U-shaped housing enclosing a chamber 7. Sidewall 6 of cartridge 1 is of sufficient depth to permit chamber 7 to accommodate the vertically oriented ribbon 8. Similarly, the base 10 of chamber 7 is of sufficient area to accept a predetermined length of fabric ribbon 8.
  • Two projecting members or parts 13a, 13b of cartridge 1 which form the arms of the U function as supports and guides for the active portion 8a of fabric ribbon 8. The spacing between portions 13a, 13b and their length is such as to accommodate the entry of print element 42 into printing position relative to the active ribbon portion 8a.
  • fabric ribbon 8 is an endless web, supplied with and prethreaded in cartridge 1 so that during typing operation, ribbon 8 is pulled to the right (as shown by the arrow on portion 8a in FIG. 1)
  • cartridge 1 contains within it fixed, integral exit guide pair members 45, 46 and 47, 48 (best seen in FIG. 4), oriented to insure smooth egress of ribbon 8 from cartridge 1 and to prevent previously entered sections 8b of ribbon 8 from being prematurely forced out of chamber 7.
  • Guide pair members 47, 48 have a gap 56 between them equivalent to the thickness of ribbon 8, which gap 56 forms the exit of cartridge 1.
  • the inner guide pair members 45, 46 are spaced slightly further apart than the exit guides 47, 48 so that the exiting portion of ribbon 8 is funneled from a multiple ribbon thickness at the entrance to guide members 45, 46 to a single ribbon thickness at guide members 47, 48 to insure proper egress.
  • Ribbon 8 may be guided in this traverse by means of a pair of chutes 58a, b, (158a, lS8b in cartridge 61) a respective one of the pair forming part of sidewall 6 in the area of projections 13a, 13b.
  • Chutes 58a, b may be provided with flanges 59 for better control, if desired (see FIG. 2a). Ribbon feed-in gear 11 (see FIG.
  • Spring member 57 has a formed end 60 adjacent feed-out guide chute 58b and is fastened to sidewall 6 by rivets 62, or the like, the length of end 60 being such that spring 57 is under stress when fastened to sidewall 6. If cartridge 1 is plastic, spring 57 may be integrally molded. Ribbon 8, being inserted between the formed end 60 and guide chute 58b, is therefore clamped between the two and subject to friction force exerted by spring 57. Ribbon 8 is thus held substantially taut since on the other side, feed gears 11, 12 are locked against reverse rotation by interaction of a detent 63 and ratchet 53 on top of gear 11.
  • the pair of spaced grooves 49 may be made eccentric with respect to shaft 55a, similar grooves 49 on gear 12 being likewise eccentric with respect to shaft 55b (note that the upper portion of gear 11 has been removed in FIG. 2a for better visibility of the members next described).
  • a pair of fingers 51a, 51b are each mounted in eccentric grooves 49 by means of their arcuate clasp members 52. A sliding fit between clasp members 52 and grooves 49 thus tends to oscillate members 51a, 51b not only together and apart, but also back and forth as eccentric grooves 49 rotate with shafts 55a, 55b.
  • Friction between clasp members 52 and grooves 49 and/or the pressure of the entered ribbon portion 8b keeps ends 64 of fingers 51a, 51b in contact with the inside of sidewall 6 (not shown in FIG. 2a).
  • fingers 51a, 51b projecting inwardly into chamber 7 serve to strip ribbon 8 from gears ll, 12 and oscillation of these fingers 51a, 51b pushes the creased ribbon 8 away from the area near gears 11, 12.
  • the oscillation may be omitted, if desired, in which case though not illustrated grooves 49 may be made noneccentric and fingers 51a, 51b are then fixed barriers which only assist in stripping ribbon 8 from gears 11,12.
  • a similar cartridge 61 having external dimensions identical to those of cartridge 1 is partitioned into two chambers 65a, 65b, the first chamber 65a being of sufficient area to accept the used portion 66b of a carbon ribbon 66 from a spoolless" supply roll 67 which supplies the active portion 66a of the carbon ribbon 66.
  • Roll 67 confined in the second chamber 65b, has a flangeless bobbin 67a and is rotatable around a pin 69 located in a slot 68.
  • the purpose of slot 68 is to enable the operator to judge the amount of ribbon 66 remaining on roll 67 so that its exhaustion will not catch the operator unawares.
  • a lift bellcrank 18 is rockably supported on pivot 5, bellcrank 18 being in the form of an inverted V with arms 19, 22.
  • Arm 19 of bellcrank 18 has an ear 40 formed into its upper margin (as seen in FIG. 1), ear 40 being of such length as to project under and give sup port to cartridge 1.
  • a lower extension 28 of bail 26 has a cam follower in the form of a cam roller 29 rotatably mounted at the free end of extension 28 (Le, remote from stud 27). Bail 26 is adapted to rock back and forth because cam roller 29 lies within the symmetrical, approximately elliptical path defined by a cam in the form ofa camming slot 30 cut into a face 31 of a gear 32.
  • Gear 32 also mounted on the support for print element 42 is in mesh with a like-mounted actuating gear 33 driven by a power roll shaft 34
  • An axial slot 70 on the surface of shaft 34 and a mating tooth 71 on gear 33 provide lateral slidability of gear 33 on shaft 34 (only in the case of thesingle print element typewriter of the example, gear 33 being laterally fixed in the case of a conventional typewriter).
  • arm 19 At its free end (i.e., remote from pivot 5), arm 19 supports a pivot 20 upon which is rockably mounted a feed bellcrank 21, which has two arms 35, 36.
  • Arm 35 sinuous in contour, has a slot 37 which controls movement of feed bellcrank 21 during the latters operation by reason of cooperation with a projecting stud 41 fixed to flange 2a oflift bracket 3.
  • Arm 36 of drive bellcrank 21 terminates in pawl 38, previously mentioned.
  • the design of the drive mechanism may be made such that a ribbon motion of half a character space occurs in each cycle (which would result in staggered arrangements of the letters I-I marked on the ribbon of FIG. 2a), or such that a ribbon motion of a full character space occurs only after two impressions have been made on record medium 14, that is, only in every other cycle of gear 33 (resulting in the aligned arrangement of the letters H not illustrated in FIG. 2a).
  • the latter type of feed motion could be achieved, for instance, by choosing dimensions of the respective bellcranks 18, 21 and the shape of slot 37 such that the second movement of bellcrank 18 would be insufficient to bring pawl 38 behind tooth 50a.
