Definitions

  • the pinions of the wheels of like denomination of the counters are connected by lengthwise movable racks having teeth meshing with the pinions and longitudinal setting movements of the racks effect synchronous setting of the counters
  • the setting movements of the racks are made by a stepped setting pawl which is selectively engaged with setting teeth formed on the racks.
  • This invention relates to a selector and stepping device for the synchronous operation of at least two multi-denominational counters in a machine such as a cash register capable of effecting printing operations.
  • a selector and setting device for the synchronous operation of at least two multi-denominational counters in a machine such as acash register capable of effecting printing operations, comprising for each counter rotatable, denominational counter wheels each having a pinion rotatable therewith, a rack for each denomination, each rack being supported for longitudinal movement and having teeth engaged with the teeth of pinions of like denomination in each of the counters, a stepped setting pawl engageable with setting teeth on the racks to effect longitudinal movements of the racks and incremental rotation of the counter wheels connected therewith, and selector means operable to control engagement of the setting pawl with the setting teeth of the racks.
  • the selector device comprises a rotatable selector shaft 1, a control lever 2, and a connecting lever 3 by means of which a stepped pawl 6 is controlled.
  • the setting device comprises a rotatable drive shaft 4, a stepping lever 5, the stepped pawl 6, and toothed racks 7 which are disposed in parallel side-by-side relation and are mounted to be slidable lengthwise on two fixed rack supports 14.
  • a locking pawl 8 cooperates with each rack 7, and each of the pawls 6 cooperates with a support or latching lever 9.
  • the teeth at the opposite ends of the toothed racks 7 engage in pinions rotatable with counter wheels 10 which are provided in the counters and which are rotatable on stationary shafts 15, so that synchronous setting movements of the two counters installed in a cash register, is ensured.
  • the setting of the counters takes place in each case shortly before the issue of a ticket by the cash register, that is to say when the latter performs a total-taking function.
  • the setting of the wheels 10 is prevented by the selector device in a manner described below.
  • the selector shaft 1 is controlled from the keyboard of the cash register so that every operation thereof is transmitted to the selector shaft 1.
  • a cam la is rotatable with the selector shaft 1.
  • the control lever 2 is urged by a tension spring 2a against the outer periphery of the cam la and is held in contact therewith.
  • the movements of the control lever 2 are transmitted to the connecting lever 3 which is provided with a slot 3a.
  • the stepped pawl 6 is provided with a pin 6a which projects into the slot 3a. By means of the pin 6a the selector device controls the engagement of the stepped pawl 6 in the teeth 7a of the rack 7.
  • control lever 2 In the position of the selector shaft 1 illustrated in FIG. I, the control lever 2 is urged by the tension spring 2a against the smaller diameter of the cam la and the connecting lever 3 as sumes its lowest possible position, in which position the slot 3a frees the stepped pawl 6 to such an extent that during a setting movement the pawl 6 can engage in the teeth 7a of the racks 7 and advance the racks to effect setting of the counters 10.
  • the selector shaft 1 turns to such an extent that the control lever 2 is engaged by the hump lb of the cam In, as illustrated in FIG. 2.
  • the connecting lever 3 then assumes its highest position and the pin 60 is so engaged by the slot 30 as to lift the stepped pawl 6 to an extent such that during the setting movement the pawl 6 cannot engage in the teeth 7a of the racks 7. In this position of the selector shaft 1 no setting of the counters is possible.
  • the setting lever 5 When on the rotation of the main shaft of the cash register the setting lever 5 performs a rocking movement about the pin 50, the curved extension 60 of the stepped pawl 6 first slides along the cross-bar 11. After the extension 60 has left the cross-bar, the tension spring 6b comes into action so that the stepped pawl 6 is engaged with one or more of the teeth 7a of the racks 7, provided that this is permitted by the selector device. In this case the racks engaged by the stepped pawl 6 are displaced by one tooth division forwards (to the left as viewed in FIG. 3).
  • a locking lever or pawl 8 has a bent end 8a which, when engaged in the teeth 7a, prevents the racks 7 from performing a rearward movement after each forward step due to the action of a return spring 7b.
  • the setting lever 5 and the stepped pawl 6 are returned to the starting positions thereof by the tension spring 5b.
  • the curved extension 6c again underlies the cross-bar 11 so that in its starting position the stepped pawl 6 is again held out of engagement with the teeth 7a.
  • a checking slide 13 is arranged to prevent any further forward setting movement of the racks by making it impossible for the stepped pawl 6 to engage in the teeth 7a.
  • the checking slide 13 which is disposed at the side of and parallel to the first rack 7, is provided with a cam13c, FIG. 1, and a stop 13a which extends over all the racks 7.
  • the checking slide 13 is pulled by a tension spring 13b into the starting position thereof shown in FIGS. 1,2, and 3 in which position it engages a stop 14.
  • a nose 72 provided on the rack engages the stop 13a and displaces the checking slide 13, against the action of the tension spring 13b out of its starting position by one tooth space in the forward direction (to the left in FIG. 4).
  • the tension spring 13b restores the checking slide to its starting position, so that the forward setting movements can be performed once again without hindrance from the checking slide 13.
  • a selector and setting device for the synchronous operation of at least two multi-denominational counters in a machine such as a cash register capable of effecting printing operations comprising for each counter rotatable denominational counter wheels each having a pinion rotatable therewith, a rack for each denomination, each rack being supported for longitudinal movement and having teeth engaged with the teeth of pinions of like denomination in each of the counters, a stepped setting pawl engageable with setting teeth on the racks to effect longitudinal movements of the racks and incremental rotation of the counter wheels connected therewith, and selector means operable to control engagement of the setting pawl with the setting teeth of the racks.
  • a device including a curved extension on the setting pawl and which in the starting position of the setting pawl is operable to hold the pawl out of engagement with the setting teeth of the racks.
  • a device including locking pawls one for each rack engageable with the setting teeth of the racks and operable to'prevent return movement of the racks following a setting movement thereof, and a pin movable with each rack and operable during the tenth forward movement of a rack to lift the locking pawl associated therewith out of engagement with the setting teeth of the rack.
  • a device including for each locking pawl a pivoted latching lever operable to retain the locking pawl in the position thereof in which it is disengaged from its rack, and a pin carried by each rack and operable to engage the locking pawl associated therewith just before the rack reaches the starting position thereof thereby to rock the latching lever out of engagement with its locking pawl to permit re-engagement of the locking pawl with its rack.
  • a device in which a spring is operable to restore the racks to the starting positions thereof, said spring being connected at one end thereof to the latching lever and at its other end to the racks.
  • a device including a checking slide arranged in parallel side-by-side relation with the racks and provided with a cam arranged to prevent the stepped setting pawl from engagement with the setting teeth of the racks'after the tenth forward setting movement of the racks and before the racks have been restored to the starting positions thereof.
  • a nose carried by each of the racks is operable on the tenth forward setting movement of a rack to engage an abutment carried by the checking slide and to move the checking slide forwards by one tooth space thereby to cause the cam on the checking slide to disengage the setting pawl from the setting teeth of the racks.
