  • 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. In most cases, 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 ribbon and the operators hands. Furthermore, because of the varying level of the ribbon on the take-up spool, during the feed operation 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.
  • Another object of the invention is to provide a ribbon cartridge in which the ribbon will not become entangled in the ribbon feed members.
  • FIG. 1 is a perspective view of a fabric ribbon cartridge 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. I or FIG. 3, showing the integral ribbon guides within the cartridge housing; and
  • FIG. 5 is an exploded perspective view of the feed gears and oscillating packing fingers of FIG. 2a.
  • FIGS. 1 through 5 show the ribbon supply and its lift and feed mechanism as particularly applied to a printing machine having a single multi-character print element 42 movable laterally over the surface of a 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 recesses or notches 9 (only one shown in FIG.
  • each cartridge 1,61 is formed in the sidewall 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 1a 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 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 projecting members 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) through an exit opening 56 of cartridge 1 to present successive fresh surfaces of ribbon 8 as the active ribbon portion between the multi-character single print element 42 and the usual record medium 14 supported on a platen 15, the ribbon movement resulting from rotation of feed rotors in the form of feed gears 11 and 12, described in detail subsequently.
  • Gears 11,12 near an entrance opening 56a to chamber 7, stuff the recently used, now inactive portion 8b of ribbon 8 into chamber 7.
  • 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 previouslyentered sections of ribbon 8 from being prematurely forced out of chamber 7.
  • Guide pair members 47,48 have a gap between them equivalent to the thickness of ribbon 8, which gap forms the exit opening 56 of cartridge 1.
  • the inner guide pair members 45,46 are spaced slightly further apart than the outer guide pair members 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, a respective one of the pair forming part of sidewall 6 in the area of projecting members 13a, 13b.
  • Chutes 580, b may be provided with flanges 59 for better control, if desired (see FIG. 2a). Ribbon feed-in gear 11 (see FIG.
  • gear 2b fixed on a vertical shaft 55a, has two spaced eccentrics 49 (for a purpose explained subsequently) and its teeth 17a mesh loosely with teeth 17b of gear 12, fixed on a parallel shaft 55b, and identical to gear 11 except that gear 12 has an extra two teeth 17b.
  • the distance between the shafts 55a, 55b and the gear 11, 12 sizes are such that space 16 between gears 11,12 is approximately the thickness of ribbon 8 so as to insure proper feeding of ribbon 8 between gears 11,12 during the gear drive operation for re-entry of now inactive ribbon portion 8b into chamber '7.
  • Fixed to shaft 55a is a drive ratchet 53, the teeth 50 of which cooperate with a feed pawl 38 to rotate feed gear 11 in the counterclockwise direction.
  • Spring 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.
  • the detent 63 can'be formed integral with a wall 6a of the projecting member 13a from a plastic.
  • the pair of spaced eccentrics 49 are eccentric with respect to shaft 550 similar eccentrics 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 on eccentrics 49 by means of their arcuate clasp members 52. A sliding fit between clasp members 52 and eccentrics 49 thus tends to oscillate fingers 51a, 51b not only together and apart, but also back and forth as eccentrics 49 rotate with shafts 55a, 55b.
  • Friction between clasp members 52 and eccentrics 49 and/or the pressure of the inactive 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 11,12 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 eccentrics 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 inactive 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 preloaded and 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 theamount 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 stud 5, bellcrank 18 being in the form of an inverted V with arms 19,22. Arm 22 of bellcrank 18 has an ear 39 formed into its upper margin (as seen in FIG. 1), ear 39 being of such length as to project under and give support to cartridge 1.
  • a lower extension 28 of bail 26 has 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 camming slot 38 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 the single 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 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 of support bracket 3. Arm 36 of feed bellcrank 21 terminates in pawl 38, previously mentioned.
  • Gear 32 having a diameter exactly twice the diameter of gear 33, each clockwise revolution (one cycle) of gear 33 therefore rotates gear 32 counterclockwise one-half revolution,
  • the first quarterrevolution, say, of gear 32 (a half-cycle of gear 33) displaces cam roller 29 from its dwell 54a to a first cam lobe 43, this lobe 43 being the higher one of two lobes 43,44 in camming slot 30, both these lobes 43,44 including a constant radius portion at their peaks so that ribbon 8 may be held still during printing, in known fashion.
  • ribbon feed bellcrank 21 being pivotally mounted about pivot 20 fixed to arm 19 of bellcrank 18, and having its pivoting motion further controlled by cooperation between camming slot 37 in its arm 35 and stud 41 fixed to bracket 3, also pivots counterclockwise, preparatory to a feeding engagement between pawl 38 and the next tooth 50a of ratchet 53.
  • Camming slot 37 is shaped such as to aid in limiting the travel of pawl 38 to an amount sufficient to pick up just the one tooth 50a.
  • FIG. 2b it will be noted that during counterclockwise rotation of bellcrank 21, the furthest retracted position of pawl 38 (shown by a dotted outline) is shifted to the left that is, behind the next tooth 50a of ratchet 53.
  • the design of the drive mechanism may be made such that a ribbon 8 motion of half a character space occurs in each cycle (as would be illustrated by staggered arrangements of the letters I-I marked on the ribbon 8 of FIG. 2a), or such that a ribbon 8 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 (not illustrated).
  • the latter type of feed motion could be achieved, for instance, by choosing dimensions of the respective bellcranks 21,18 and the shape of slot 37 such that the second movement of bellcrank 18 would be insufficient to bring pawl 38 behind tooth 50a.
  • the power roll clutch is disengaged, of course, rendering power roll shaft 34 and lift and feed bellcranks 18,21 stationary until another character imprint is desired, at which time the abovedescribed operational sequence is repeated upon depression of a further keybutton.
  • a spoolless ribbon cartridge for printing machines with at least one print element comprising a. a housing having a first chamber with an entrance opening and a second chamber with an exit openb. a roll of carbon ribbon preloaded in said second chamber, said carbon ribbon having an active portion and an inactive portion and said inactive portion being storable in said first chamber,
  • An improved cartridge for a ribbon for a printing machine having a print element, means for pivotally mounting the cartridge, and means for oscillating the cartridge on the pivotal mounting means, the cartridge having a housing containing a chamber for the ribbon and two projecting members on the housing with free ends and openings in the free ends for the ribbon to span the projecting members to receive impacts of the print element, wherein the improvement comprises:
  • a detent that engages the ratchet so that the ratchet can rotate in only one direction.
