Definitions

  • This invention relates to a high speed set up device for a ten key adding or like machine comprising a set up carriage provided in each order with a column of settable stop pins and adapted to be transversely displaced step by step, under the control of means cooperating with a predetermined one pin of said columns upon setting up each order of an amount, and comprising a group of setting members individually connected with a corresponding numeric key stem and adapted to be moved from a rest position to an operated position for setting a corresponding stop pin plus said predetermined one pin of each one of said columns.
  • the setting device which is characterized in that a projection integral with each one of said key stems normally enters a notch provided on the corresponding setting member to positively move this latter to said operated position at the depression of the corresponding numeric key, each setting member being integral with a cam element adapted to engage a stationary member for disengaging said notch from said projection when said setting member approaches said operated position to cause a spring tensioned between said setting member and the corresponding key stem to restore said setting member independently from said key stem.
  • FIG. 1 is a left hand partial longitudinal sectional view of a ten key adding machine incorporating a high Speed set up device according to the invention
  • FIG. 2 is a partial plan view of the set up device
  • FIG. 3 is a transverse sectional View of a detail of the set up device.
  • the set up device is incorporated in a conventional ten key adding machine and comprises a group of ten keys 3 (FIG. 1) adapted to set up an amount order by order on a set up carriage 4.
  • This latter is provided in each order with a column of settable stop pins, comprising a pin 6 for the figure zero, eight pins 7 for the figures 3,417,917 Patented Dec. 24, 1968 ice from one to eight, and a settable escapement pin 12.
  • the set pins 6 and 7 are adapted to differentially arrest a projection 9 provided on each one of a set of actuators 8, which are cyclically movable upwards.
  • the carriage 4 is transversely slidably on a stationary bar 11 and is urged leftwards (downwards in FIG. 2) by a spring not shown in the drawing to contact with the leftmost unset pin 12 an escapement dog 13.
  • Each key 3 (FIG. 1) is secured to a stem formed of a lever 14 pivoted on a stationary shaft 15, four shafts 15 being provided for the ten keys 3.
  • Each lever 14 is connected to a corresponding setting member or a slide 17 having a rear end guided in a corresponding notch of a stationary comb plate 30, which is located near the carriage 4.
  • the slides 17 are movable rearwards from the rest position shown in the drawing to an operated position.
  • each slide 17 is provided with a finger 21 (FIG. 2), all the fingers 21 being vertically aligned in front of the first left hand unset column of pins 6, 7 and 12.
  • Each slide 17 is also provided with a shoulder 22 adapted to cooperate with a vertical universal bar 23 (FIG. 1) integral with a slide 24. This latter is longitudinally slidable on the comb plate 30 and on a stationary plate 26 and is normally urged by a spring 25 to contact the plate 26.
  • the bar 23 is provided with a finger 27 adapted to engage an escapement pin 12 and with a projection 28 adapted to engage a rack 29 (FIG. 2) provided on the carriage 4.
  • each lever 14 and the corresponding slide 17 Tensioned between each lever 14 and the corresponding slide 17 is a spring 16 normally urging the lever 14 to contact one side of a stationary bar 18.
  • the forward end of each slide 17 is provided with a bent lug 19 normally urged by the spring 16 to contact the opposite side of the same bar 18.
  • the bar 18 is adapted to arrest a shoulder 20 of the lever 14 when the corresponding key 3 is depressed.
  • Each slide 17 is also provided with a notch 32 normally entered by a projection 33 (FIG. 3) integral with a bent lug 34 of the lever 14 and adapted to engage a rear edge 31 (FIG. 1) of the notch 32.
  • the rear end of each slide 17 is provided with a cam element formed of an inclined bent lug 39 adapted to engage the bar 18 when the slide 17 is displaced rearwards to its operated position.
  • the lever 14 is provided with a pair of elements, comprising a tooth 36 and a projection 37 (FIG. 3) of the lug 34, which normally embrace the slide 17 so as to guide same longitudinally and to prevent its transverse displacement.
  • the tooth 36 is also provided with a lug 38 adapted to limit the downward movement of the slide 17 about the corresponding notch of the comb plate 30.
  • the high speed step device operates as follows:
  • the lug 39 engages the bar 18, thus causing the slide 17 to rock about the corresponding notch of the comb plate 30, until disengaging the projection 33 from the notch 32 of the lever 14, whereby the slide 17 is released.
  • the slide 17' is now quickly restored to return forwards by the spring 16, While the spring restores the universal bar 23, even though the key 3 is held depressed, whereby the slide 17 is restored independently from the key 1.
  • a high speed up device for a ten key adding or like machine having a group of numeric keys, a set up carriage provided in each order with a column of settable stop pins, means adapted to cooperate with a predetermined one pin of said columns for controlling a step by step movement of said carriage upon setting up each order of an amount, a group of setting members movable from a rest position to an operated position for setting a corresponding stop pin plus said predetermined one pin of each one of said columns, a key stem secured to each one of said numeric keys, and comprising in combination:
