Definitions

  • ABSTRACT A mechanical counter comprises a plurality of presettable digit wheels, a plurality of counting digit wheels associated with respective ones of said presettable digit wheels, and a lever, which is movable about a [451 May 14,1974
  • Said presettable digit wheels are carried by said lever for rotation about an axis which is parallel to and spaced from said pivotal axis.
  • the lever is pivotally movable between a counting position, in which said presettable digit wheels are in engagement with said counting digit wheels and adapted to be driven thereby, and a presetting position, in which said presettable digit wheels are disengaged from said counting digit wheels.
  • a presetting mechanism for presetting each of said presettable digit wheels and has teeth on said presettable digit wheel, first and second stationary cross-bars, which are transversely spaced apart and extend parallel to said pivotal axis, a presetting slider having a stepping nose and a lug, a tension spring connected between said lug and said first cross-bar, and actuating means operable to move said slider against the force of said spring from said-first position to a second position.
  • the tension spring tends to return said slider from said second position to said first position.
  • Said first and second crossbars limit said movement of said slider to said first and second positions, respectively.
  • Constraining means are provided, which constrain said slider to move from said first position to said second position along such a path that said nose engages one of said ratchet teeth and imparts a predetermined angular movement to said presettable digit wheel when said lever is in said presetting position, and which permit said nose to skip said ratchet teeth as said slider returns from said second position to said first position when said lever is in said presetting position.
  • . 1 M CHANICAL COUNTE are in mesh with stepping wheels, whichare disengageable when resetting is desired, presettable digit wheels,
  • the resetting or zero-setting operation In presettable counters, the resetting or zero-setting operation must be reliably controlled and the presetting mechanism is of like importance for the satisfac tory operation so as to avoida wrong presettingas a result of malfunction and misoperation'.
  • the presetting device provided according to the invention for presettable counters of the kind defined first hereinbefore is characterized in that presetting sliders are longitudinally slidably guided on bars and provided with switching noses, and these slide'rs' are held'by respective tension springs connected between a barand a slider-operating'lever provided at the end of the slider, which spring serves to return the slider and enables it to skip a detent position. Because one spring serves two functions, the structure is -simplified and trouble is avoided.
  • the presetting sliders have guide slots, one of which serves to guide the slider for a' sliding and rotational movement for resiliently skipping the detent positions, and the second guide consists of a slot which is oversize in width and has a surface against which the slider is held by spring force;
  • the presetting sliders have lugs, into which the springs can be hooked and which have such a length as to enable the dual function of the spring, namely return and detent position skipping.
  • the presetting sliders cooperate with push-buttons which are inserted in apertures of the hood and which snap into detent positions under the action of spring elements, which are provided on and particularly comolded with said push buttons and which in said detent positions serve also to limit the return movement of the push-button.
  • FIGS. 1 to 3 show the presetting device in position of rest and in two operating positions, during forward and return movements, respectively.
  • FIG. 1 shows the embodiment of the invention in a state in which it is ready to count.
  • a plate 1 carries crossbars 2 and 3, which serve as guides for the preset ting sliders 4, which are urged by respective tension springs against the cross-bar 3 in position of rest.
  • Each presetting slider 4 is provided at its end with a lug 6, into which the tension spring 5 is hooked. The hooking of each spring in a lug 6 and the guiding cross-bars 2 and 3 determine the spring action on the presetting slider 4 in the longitudinal direction to return the pushbutton and in a radial direction for skipping adetent position.
  • the cross-bar 2 serves also as a pivot bearing.
  • FIG. 3 shows the bridge 10 in the same position and indicates how the'stepping nose 19 of the presetting slider 4 skips over a ratchet tooth 18 of the associated presettable digit wheel 7 during the return movement of the presetting slider 4.
  • the slot 23 which is oversize in width and engages the cross-bar 3 permits of an outward pivotal'movement of the presetting slider 4 about the cross-bar 2 against the force of the tension spring 5.
  • each push-button 20 is separate from the associated presetting slider 4 and is mounted in a guide 24 in the cover hood 25. Because the push-button has an enlarged head, it can be inserted from above so that the two locking springs 26 integrally connected to the bushbutton snap into position. These detent springs 26 serve also to limit the returnmovement of the pushbutton.
  • the embodiment which has been selected by way of example consists of a presettable adding counter.
  • Such counter can be preset in that the presettable digit wheels are swung off and set and that the counting mechanism is set to zero at the same time by an operation of the zero-setting key. This sequence of operation is enforced because the presettable digit wheels cannot be swung out for a presetting unless the zero-setting key has been operated. This is known and has not been specifically shown. Other known functions for the generation of a signal have also been omitted because they are not related to the presetting device according to' the invention.
  • said tension spring is arranged to urge said nose a tension spring connected between said lug and said 0 toward said ratchet teeth.
