Definitions

  • the Invention relates to a resettmg device for the May 15, I970 Germany ..P 20 23 80.8 i h r ll of counters with transmission pinions I which are disconnected during the return of the cipher [52] US. Cl. ..235/144 HC rolls by resetting fingers acting upon cams of the [51] Int. Cl. ..G06c 15/42 cipher rolls.
  • the axle shaft of the transfer pinions is [58] Field of Search ..235/144 HC supported in slotted holes stationary in relation to the cipher roll axes.
  • the transfer pinions serve the purpose of stepping up the cipher roll of the next higher magnitude by one step after the preceeding cipher roll has completed one revolution.
  • the transfer pinions have to be disengagedfrom the cipher rolls during the resetting process because these cipher rolls have to be able to turn freely during the engaging of the resetting fingers on the appropriate cardioids or cam surfaces.
  • This chronological succession of the motional work cycles serves the purpose that on the one hand, the cipher rolls do not already receive a torsional moment through the resetting before the transfer pinions have been disengaged since otherwise these transfer pinions could lock or be destroyed, and that in addition thereto after their zero position, the cipher rolls are rotationally fixed before the re-engaging of the transfer pinions and can, consequently, not be moved under the influence of vibrations of the like.
  • a reset slide supported at a lateral sheet bar which can be operated either manually or eleetro-magnetically.
  • a lever arm is set up in rotary fashion which is rigidly connected with a return comb pivoting on an axle, carrying the reset fingers.
  • a pinion bridge carrying the transfer pinions is set up, likewise pivoting, on the same axle as the return comb, between the return comb and the pinion bridge, a friction coupling is provided.
  • the return comb After the engaging of the transfer pinions, the return comb is deviated in relation to the pinion bridge again so that the reset fingers leave the cardioid grooves and the cardioids. With normal stress, this counter functions in sufficiently dependable manner. In spite of this disturbances during the return process may occur. This can, for example, take place when the return slider is charged in jerky or sudden manner. In this case, the reset fingers may since their motion is necessarily coupled with the motion of the return slider engage with the cardioids before the pinion bridge has a certain inertial and its deviation is only effected over a frictional force as a function of the motion of the return slider.
  • Another known counter is constructed in similar manner and has likewise a friction coupling between its return comb and the pinion bridge carrying transfer pinions.
  • the shaft common to all transfer pinions is, in addition to being supported in the pinion bridge, still set up in slotted holes extending in the direction of motion of the return slider. In this case, these slotted holes serve exclusively as additional guideways for the axle shaft of the transfer pinions. Because of this, this counter has likewise the same previously described disadvantages.
  • the reset fingers can act upon the cardioids or cam surfaces before the transfer pinions are disengaged and that the cipher rolls are through vibrations or the like before the re-engaging of the transfer pmlons.
  • the return comb has a cam lying between two stops of the reset slider over which cam the return comb can be moved.
  • the pinion bridge set up on the same shaft as the return comb is in this case connected with the reset slider over a leg spring which is supported at the axle shaft of the transfer pinions and at the cam. This spring serves simultaneously as top dead center spring 'for the cam.
  • this counter when the reset slider is manipulated, first of all the pinion bridge is moved through the leg spring connection. Thereafter, the cam engages with one stop of the reset slider so that the return comb is moved and, consequently, the cipher rolls are brought into the zero position.
  • a return comb and a pinion bridge are likewise set up on a common shaft, in which case the pinion bridge and the return comb are pressed apart through a spring.
  • two stops are provided at the reset slider of this counter one of which stops presses the pinion bridge in the direction towards the cipher rolls when the reset slider is not operated while the other one acts directly upon the return comb when the reset slider is operated. Because of the spring, the return comb as well as the pinion bridge is moved when the reset slider is operated. In this case, the turning paths are proportioned in such a manner that the transfer points are disengaged before the reset fingers can act upon the cardioids.
  • the pinion bridge may remain in its disengaged position through jamming and possibly also through inertia and the stopping of the reset fingers may already be cancelled through the reset slider again in spite of this.
  • the cipher rolls would be, although they should not be freely rotary. in their position.
  • This invention overcomes the disadvantages of the known resetting devices and solves the tasks of attaining a positively actuated succession of the described motional processes.
  • This feature is achieved in that, after the setting to zero of the cipher rolls, the reset fingers are capable of being engaged in that position in which they rest against the cardioid segments assigned to the zero position until the transfer pinions engage with the cipher rolls again. Then the engaging of the reset fingers can be cancelled, and the axle shaft of the transfer pinions is in operative connection with a reset member in such a manner that it is necessarily removed from the cipher rolls at the time of the beginning of the motion of the reset member in return direction. The reset member only arrives at an operative connection with the reset fingers after the transfer pinions have disengaged from the cipher rolls.
  • the moving of the pinion bridge is necessarily coupled with the motion of the reset member.
  • the reset fingers hold the cipher rolls in their zero position through their catch until the transfer pinions have engaged with the cipher rolls again. Therefore, when the reset member is operated, the motional processes of (l) the disengaging of the transfer pinions, (2) the acting of the reset fingers upon the cardioids and the setting to zero of the cipher rolls, (3) the holding of the cipher rolls in their zero position through the reset finger, (4) the re-engaging of the transfer pinions and (5) the returning of the reset fingers into their rest position, follow one another chronologically by necessity.
  • the mentioned reset member is preferably a reset slide which, for example, embraces the axle shaft carried in slotted holes extending in the direction of the motion with a bore. Thereby, an operative connection is created through which necessarily at the beginning of the movement of the reset slide, the transfer pinions are deviated.
  • a further advantageous execution of the invention consists of the feature that the axle shaft of the transfer pinions seizes through slotted holes of the reset member proceeding in inclined fashion in relation to its slotted guide holes.
  • ratio of the course of the reset member or reset slide to the deviation course of the transfer pinions is greater.
  • the transfer pinions only need to be deviated for a relatively short distance and, nevertheless, a longer path of the reset member or reset slide is available for the operating of the reset fingers. This is favorable because on the one hand, as a rule, the deviation path of the transfer pinions has to be kept as small as possible in order to hold them in the proper position so that they engage into the proper positions of the cipher rolls when they are swung back again.
  • the path of the reset member should be as great as possible for the moving of the reset fingers so that not too high of a force is necessary for the resetting and the reset fingers do not engage too early with the cardioids of the cipher rolls at the beginning of the movement of the reset member.
  • a further development of the invention through which the just mentioned ratio between the path of the reset member and the deviation path of the transfer pinions can be rendered even more favorable consists of the feature that the slotted holes of the reset member consist respectively of a slotted hole extending in the motional direction of the reset member which slotted hole passes over into a slotted hole thereto.
  • the deviation path of the transfer pinions can be kept arbitrarily small and the path of the reset members can be rendered arbitrarily big. Accordingly, the transfer pinions only need to be deviated just so far that they just disengage from the cipher rolls. Since their devia' tion path can be rendered constant, they can in this position, be placed against suitable stops to secure their position.
  • a further advantageous development of the invention consists of the feature that the catch of the reset fingers can be terminated directly through the axle shaft of the transfer pinions.
  • this catch is terminated directly by the axle shaft, it is assured that the stopping of the cipher rolls in their zero positions is only eliminated after the transfer pinions have re-engaged with the cipher rolls again. If this catch is terminated through other members, it may because of manufacturing tolerances or wearing manifestations possibly be difficult to accurately determine the moment of the unlocking of the cipher rolls.
  • FIGS. 1-3 show similar longitudinal sections of a counter with a reset device according to the invention, in which case elements which are not essential for the invention have been omitted.
  • the resetting device is shown during its operation with transfer pinions completely swung out, but with reset fingers not yet engaged;
  • FIG. 3 the resetting device is shown in that position in which the transfer pinions have been deviated and the reset fingers are engaged in the position corresponding to the zero position of the cipher rolls.
  • a casing l is shown with cipher rolls 2 provided with cardioids or heart-shaped inner cam surfaces 3 designed as inner curves.
  • reset fingers 5 can move over axle journals 4 which are jointly rotary with fingers 5 around a shaft 6 as a bridge.
  • An operating lever 7 is rigidly connected with this reset finger bridge, which lever 7 is pivoted at one end of an intermediate lever 8. The other end of the lever 8 engages with a fork over a pin 9 stationary in the casing l.
  • a reset slide member 10 designed in U-shaped manner is set up in casing l in such a manner that its U- shaped legs extend on both sides of the cipher rolls 2 while the bottom of the U runs outside of and transversally to the casing 1.
  • the reset slide member 10 is pivoted at an armature l2 rotary around a shaft 11.
  • the armature 12 serves to guide reset slide member 10 and simultaneously serves as a magnetic armature which can be pulled up against an electro-magnet 13.
  • the reset slide member 10 can be manipulated manually or by electromagnet 13 toward the right in the direction of the arrows shown in FIGS. 2 and 3.
  • the reset slide member 10 has a recess 14 into which an offset 15 ofintermediate lever 8 extends.
  • reset slide 10 has at each of its legs an angularly shaped slotted hole which respectively consists of a slotted hole 16 extending in the direction of the motion of the reset slide member 10.
  • the slotted hole 16 passes over into a slotted hole running vertically thereto.
  • the reset slide member 10 embraces an axle shaft 18 over transfer pinions 19.
  • This axle shaft 18 is additionally supported in slotted holes 20 proceeding in inclined manner, stationary in relation to the axle of the cipher rolls 2.
  • these slotted holes 20 are defined in bearing ribs 21 rigidly connected with casing l.
  • a two-armed stopping lever 23 is pivotal around a shaft 22 which shaft 22 is stationary in casing l.
  • the lever 23 is provided with a nose-shaped end or catch 24 at one lever end with which it can engage over an offset 25 at the reset lever bridge. With its other free lever end 26, stopping lever 23 is directed into the range of axle shaft 18.
  • a two-armed spring 27 is placed around shaft 22 and is supported at lever end 26 and shaft ll so that nose-shaped end 24 of stopping lever 23 is biased in the direction towards offset 25 at the reset lever bridge.
  • this reset slide member is pulled back again into its initial position through a spring 29.
  • axle shaft 18 of the transfer pinions 19 arrives at the right end of slotted hole 16 again so that it has to necessarily slide up into its stationary slotted guide holes 20 again and therewith causes the transfer pinions 19 to engage with the cipher rolls 2.
  • axle shaft 18 strikes against the free end 26 of blocking lever 23 and, consequently, terminates the blocking of the reset fingers 5 at a moment at which the transfer pinions 19 are guaranteed to be engaged with the cipher rolls 2.
  • this reset slide It acts with the right edge of its recess 14 upon offset and thereby returns reset fingers 5 into their rest position again.
  • the angular slotted hole could also be setup in armature 12 or another reset member (not shown)'instead of in the reset slide 10.
