  • the present invention relates to ribbon lifting arrangements for typewriters and the like.
  • the ribbon is extended between a pair of ribbon guides proximate the typing zone and is selectively elevated by a ribbon lifter which subjects the lower edge of the ribbon supported by the ribbon guides to substantial stress.
  • the ribbon is never taut at the printing zone and tends to slide up and down thereby preventing a precise feeding of the ribbon. This is particularly troublesome when the feed increments are very small.
  • FIG. 1 is a top view of a ribbon arrangement for a typewriter or the like
  • FIG. 2 is a side view of the ribbon arrangement illustrated in FIG. 1 taken from the left side thereof;
  • Flg. 3 is a magnified view partly in section of a portion of the ribbon lifting arrangement illustrated FIG. 2;
  • FIG. 4 is an oblique front view of a portion of the right-hand corner of the ribbon arrangement illustrated inFIG. I.
  • the typewriter ribbon arrangement for a typewriter or the like which is illustrated in FIGS. 1 to 4, is operated with each actuation of a type key and includes a structure for defining the ribbon circuit, a ribbon lifter and a ribbon feed arrangement for advancing the ribbon along the ribbon circuit and through the ribbon lifting arrangement.
  • the ribbon feed arrangement includes a supply spool 10, a take-up spool 12 and a feed roller 14, which is selectively and conjointly driven with the take-up spool 12 in a known manner to unwind the ribbon 16 from the supply spool 10, to advance the ribbon 16 about the ribbon circuit and to rewind the ribbon on the take-up spool 12.
  • the supply spool 10, take-up spool 12 and feed roller 14 are, as shown in FIG. 2, suitably mounted on the underside of a support plate 18 adapted to be mounted on a single element typewriter carriage (not shown), which is selectively traversed across a typewriter platen or the like.
  • the ribbon circuit is defined by a pair of ribbon vibrator levers 20, 21, each of which includes an integral ribbon guide assembly 22 at one end thereof.
  • One of the ribbon vibrator levers 20, is pivotally secured at the other end by means of a pin or the like 24 extending from a depending ear 25 of mounting bracket 26,
  • the other end of the second ribbon vibrator lever 21 includes as best seen in FIG. 3 a vertically oriented fork member 28 which has a downwardly depending element 30 and an opposite upwardly projecting element (not shown).
  • a deflection roller 34 is fixedly located intermediate these opposing elements and has an inner diameter selected to permit the insertion of one leg 36 of a wire hinge clip 37.
  • the other leg 38 of the wire clip, which extends in a direction perpendicular to the axis of the deflection roller is received in a channel defined by a plurality of alternatively oriented grooves in the legs 39 of the down wardly projecting tab portion 40 of a second mounting bracket 42 also suitably secured to the other end of the support plate 18.
  • intermediate deflection rollers 50, 52 which are mounted on the vibrator levers 20, 21 at the locations where the ribbon direction is changed, have a fixed orientation with regard to the vibrator levers 20, 21.
  • the first mounting bracket 26 also has an integral depending member 61 having a knife-edge 62 for supporting a non-rotatable, self-adjusting slotted cylindrical ribbon guide or deflector member 64 having a knife-edge receiving groove 66.
  • the self-adjusting deflection member 64 about which the ribbon run 67 is directed as shown in FIG. 1 will automatically angularly adjust about the knife edge 62 as the vibrator arms 20, 21 carrying the ribbon is elevated about pivots 24 and 38.
  • the drag at the ribbon guide 64 is small thereby permitting the utilization of a non-rotatable cylindrical member 64
  • the drag at the deflection roller 34 is substantial thereby making it preferable for a roller to be utilized.
  • the ribbon is only twisted at one location, that is, between the comer deflection roller 34 and the feed roller 14 and such twisting only takes place about its center line or neutral fiber. No deformation of the ribbon l6 occurs at other locations and ribbon 16 is not subjected to any uneven stress except at this location. Additionally, since the pivot axis of the ribbon circuit defined by pin 24 and wire leg 38 is situated at the farthest rearward location on the carriage assembly, the actual angular movement of the ribbon circuit proximate the pivot axis is very slight, and accordingly, even at the deflection roller 34 the ribbon is subjected to very minor stressing.
  • a ribbon guide arrangement for business machines comprising support means,
  • said means! for directing said length of ribbon including a ribbon deflector member adjacent the pivot of said first vibrator lever to direct ribbon from said supply spool to said guides on said vibrator levers, and means on said support means for pivotally supporting said deflector member about a point intermediate its ends whereby on movement of said vibrator levers to elevate ribbon opposite said printing zone said deflector will adjust its position to accommodate ribbon stresses.
  • said means for directing said length of ribbon further including a roller deflector mounted on the pivot end of said second vibrator lever and a pivot wire supporting by said roller deflector and extending at right angles therefrom, and means on said support means for supporting said pivot wire.
  • a ribbon guide arrangement as recited in claim 1, said means for directing said length of ribbon further including ribbon deflectors supported on and intermediate the ends of said vibrator levers.
  • said deflection means comprising guide rollers.
