Definitions

  • step displacing means whereby it must be located far from said pin bed and needs additional step by step displacing means.
  • control device which is characterized in that said carriage is also provided with a second zero stop plate located under the zero pins of the left group of orders of said carriage and adapted to cooperate with a counterstop provided on each actuator of the sole' right group of actuators for disabling the non-significant orders of the right group of actuators.
  • the adding machine comprises a totalizer generically indicated by the numeral 1 and split in a right portion 2 and a left portion 3.
  • the right portion 2 is provided with a fugitive one mechanism known per se and not shown in the drawing.
  • the portions 2 and 3 are adapted to cooperate with two groups of actuators, namely a right group of actuators 4, and a left group of actuators respectively, which are differentially movable upwards under the control of a cyclically operable universal bar 6.
  • the actuators 4 and 5 are adapted to be controlled by a transversely traveling stop pin carriage 7 comprising in each order a column of settable stop pins 8 for the figures from zero to eight.
  • the actuators 4 and 5 are provided with a shoulder 9 adapted to be arrested by the set up pins 8 and are connected each one by means of a rack 10 to a typewheel 11 pivoted on a hammer 12.
  • the hammers 12 may be individually released by a corresponding zero printing control latch 14 sensing the corresponding actuator 4 or 5 to cause the wheels 11 to print the amount represented thereby on a paper platen 13.
  • Each latch 14 is provided with a projection 15 which in a known manner draws the latch 14 of next lower order to cause the significant Zeros to be printed.
  • the latch 14 sensing the lower order of the actuators 5 is deprived from the projection 15, whereby the printing device is split in two portions and comprises two groups 16 and 17 of typewheels 11 corresponding to the portions 2 and 3 of the totalizer 1.
  • the machine is provided with a conventional ten key keyboard, only one key 22 of which is shown'in the drawing.
  • Each key 22 is secured to a rearwards movable forked setting member 23 provided with a pair of projections 24 and 25.
  • the projection 24, and 25 respectively is normally located in front of a pin 8 of the first column of the group 18, and of the group 19 respectively.
  • Each setting member 23 when moved rearwards pushes a slide 26, which is provided with a projection 27 adapted to set up an escapement pin 20, whereby the carriage 7 may be moved one step leftwards.
  • Integral with the carriage 7 is a first zero stop plate or comb 28 having teeth 29 adapted to arrest the shoulders 9 of the left group of actuators 5, and a second zero stop plate or comb 30 having teeth 31 adapted to arrest a second counterstop or shoulder 32 provided on each actuator 4 of the sole right group, the actuators 5 of the left group being deprived from the shoulder 32.
  • the comb 30 is located under the zero pins 8 of the right group 18.
  • a lever 33 Fulcrumed on a stationary pivot 34 is a lever 33 comprising a locking arm 35 adapted to engage the lowest tooth of the left group of actuators 5, but normally disengaged therefrom.
  • the lever 33 is normally urged by a spring 36 to contact a pin 37 of a common member or lever 38 fulcrumed at 39.
  • the lever 38 is urged by a spring 41 prevailing over the spring 36 to contact a stationary pin 40.
  • the lever 38 may be operated by a tapered edge 42 of the stem of a conventional total taking key 43, as well as by a tapered edge 44 of the stem of a conventional subtract key 45.
  • the lever 33 is provided with a projection 46 adapted to cooperate with an end 47 of a predisposing element or slide 48 adapted to be manually set in each one of two positions I and II.
  • the slide 48 is provided with a slot 49 slida-ble on a stationary pin 50 and with an aperture having a locking edge 51 urged by a spring 52 to contact a stationary pin 53.
  • the slide 48 is also connected through a link 54 to a bail 55 fulcrumed on two stationary pivots S6 and adapted to cooperate with a projection 57 of the left group 17 of hammers 12.
  • the control device operates as follows.
  • the totalizer 1 is engaged with the actuators 4, and 5 respectively, which are now restored by the universal bar 6, whereby the set up amount is simultaneously accumulated in both the portions 2 and 3 of the totalizer 1.
  • the carriage 7 is temporarily returned at right of the actuators 4, in order to clear the carriage 7 in a known manner. Thereafter the carriage 7 is released and under the urge of its spring is arrested by the escapement dog 21 through the first left hand pin 20, whereby the carriage 7 returns in the initial position shown in the drawing.
  • the total key 43 When all the amounts relating to a predetermined transaction have been recorded on the paper and accumulated in both portions of the totalizer, the total key 43 is depressed to cause a total taking machine cycle. Furthermore, the tapered edge 42 of the key stem rocks the lever 38 counterclockwise, thus releasing the lever 33 from its pin 37. The spring 36 rocks now the lever 33 clockwise thus engaging the arm 35 with the lowest tooth of the actuators 5. Therefore during the total taking cycle, the right group of actuators 4 clears the corresponding portion 2 of the totalizer 1, while the left group of actuators 5 is locked by the arm 35 and cannot clear the portion 3 of the totalizer 1. The actuators 4 control the group'16 of typewheels 11 for printing on the paper the total of the transaction, whereas the portion 3 retains all the accumulated amounts, thus assuming the function of a grand total totalizer.
  • subtotal key operates the lever 38 in a manner similar to the total key 43.
  • the paid money is set up into the ten key keyboard and the subtract key 45 is depressed.
  • the tapered edge 44 of its key stem rocks counterclockwise the lever 38 in a manner similar to the total key 43, whereby during the subtract cycle the arm 35 prevents the left group of actuators 5 from being moved upwards.
  • the paid money is subtracted only from the portion 2 of the totalizer 1, even if it has been set up in both groups of columns 18 and 19, and it is printed on the paper.
  • the cashier may take the grand total by clearing the portion 3 of the totalizer 1.
  • the slide 48 is manually predisposed in its rearward position II shown by broken lines in the drawing. Then the link 54 rocks the bail 55 counterclockwise, thus releasing the projection 57 of the left group 17 of the hammers 12.
  • the end 47 of the slide 48 is placed into the path of the projection 46 of the lever 33.
  • the lever 33 is prevented by the end 47 from rocking clockwise, whereby the actuators 5 are not locked. Since the portion 2 of the totalizer 1 is cleared upon each transaction, now the sole left portion 3 is cleared and the grand total is thus printed on the paper.
