These two return arms 24 are subjected to a returnresilient action by a coil compression spring 25 located inside a hole 26 provided in the body 16 of the support 15 and connecting the two opposed openings 17, 18. This spring 25 tends to spread apart these two return arms 24.
  • Control arms 27 extend towards the inside of the support 15.
  • the ends of the two corresponding arms 27 are located approximately in a middle longitudinal plane of the support 15, this plane containing also the axis of the shaft 7.
  • the ends of these corresponding arms 27 comprise a lateral dog 28.
  • These arms 27 extend within the space located between the support 15 and the ciphered wheels 8 and are maintained in rest position, against the action of spring 25 in a manner to be described herebelow.

  • In rest position shown in the drawing, defined'by the return spring 25 the end of this working arm 32 rests on the lower surfaceof the upper face of the body 16 of the support 15.
  • the working face 31 of this actuating lever 30 is located in the path of elements, set in active position, of the storing device.
  • the driving shaft 7 driven by aforementioned direction reverser and gear train (not shown), is driven for example in direction of the arrow f which tends to drive the ciphered wheels 8 also in the direction of this arrow f.
  • these ciphered wheels 8 are locked in an angular position which is determined by the ends'of the stop arms 29 against one of which, according to the direction of rotation of the totalizer, abuts one or the other of the abutment members 13 or the carryover abutment l4.
  • This intermediate lever 36 comprises further a control arm 33 a part of the upper surface 42 of which is located under the two lateral dogs 28 of the control arms 27 whereas its extremity constitutes a stop 43 which can be placed in the path of the abutment member 13 of a ciphered wheel 8.
  • This intermediate lever 36 is subjected to the action of a return spring 45 tending to displace the stop 43 towards the ciphered wheel 8 but lever 36 is maintained in rest position by the carryover lever 37 and i shoulder 40 of arm 41 tends to apply the upper arm 38 front of the locking device, this element enters in contact with the working face 31 of the actuating lever 30 and causes a tilting of it in direction of the arrow g around the axis 20. This tilting causes an upward displacement (FIG. 1) of the end of the working arm 32 of the said lever 30 which drives, against the action of the return spring 25, the control arm 27 of the locks 23 in its displacement.
  • the action of the elements of the storing device on the actuating lever 30 is very short, the locking device is free during this period which is less than the period necessary for the ciphered wheel 8 to effect a tenth of revolution so that it can be displaced for each actuating of the lever 30 only of the value corresponding to the passage of one cipher to the next.
  • the upper arm 38 of the carryover lever 37 enters in contact through its free end with the surface of the corresponding ciphered wheel 8.
  • This free end presents a rounded shape acting as a cam.
  • This free end is located in the path of the carryover abutment 14 but not in the path of the abutment members 13.
  • the cam constituted by said free end causes under the action of the passage of the carryover abutment 14 the tilting in the direction of the arrow k of the carryover lever 37.
  • the upper arm 38 of the carryover lever 37 rests on the periphery of a ciphered wheel 8 corresponding to a given decade, but that the lower arm 39 of this same carryover lever 37 acts during an angular displacement of this upper arm 38 to release the lever 36, which tends' to swing control arms 27 on the locks 23 relative to the ciphered wheel 8 of the immediately upper decade.
  • This calculating device comprises further a cycle control cam 46 carried and rotated by the shaft 2.
  • This cam comprises three parts approximately equal in angular amplitude.

  • This cam 46 comprising the parts A, B and C, cooperates with the end 47 of an arm 48 of the carryover stirrup 49 pivoted on the axle 20.
  • This carryover stirrup 49 extends across the whole width of the calculating device and comprises an abutment 50 cooperating with the end face of the intermediate carryover lever 36. According to the position of the cam 46 this stirrup 49 may be placed in three distinctive positions:
  • FIG. 3 An advanced position (FIG. 3) for which it enters into contact with the arm 41 and displaces the inter- Mediate carryover lever 36 further away than the rest position against the action of the return spring. This position corresponds to the rearming of the calculating device.
