摘要:
La présente invention concerne un totalisateur à tambours coaxiaux rotatifs du type connu comprenant : un bati (350) qui loge, un arbre principal, une pluralité de tambours coaxiaux rotatifs (200) montés sur l'arbre principal, munis de chiffres sur leur périphérie externe et pourvus sur chacune de leurs faces transversales à l'arbre principal, d'une part de dents d'entraînement, d'autre part de dentures d'indexage (240), un ressort (100) exerçant un effort axial sur les tambours pour maintenir en contact les dentures d'indexage prévues sur les faces en regard de chaque paire de tambours adjacents, un arbre secondaire parallèle à l'arbre principal, et une pluralité de pignons d'entraînement coaxiaux rotatifs montés sur l'arbre secondaire respectivement en regard des dents d'entraînement des tambours de sorte qu'après une révolution complète, chaque tambour entraîne le tambour d'ordre supérieur par l'intermédiaire d'un pignon associé, caractérisé par le fait que le ressort (100) est formé d'une lame engagée sur l'arbre principal, à l'une des extrémités de l'empilement de tambours, immobilisée à rotation autour de l'axe de cet arbre principal sur le bati et munie de dentures d'indexage (140) aptes à coopérer avec les dentures d'indexage liées à la face en regard du tambour d'extrémité adjacent.

A gear arrangement includes a first gear wheel 10 having a section 12 with missing teeth. A second gear wheel 14 is arranged to mesh with the first gear wheel 10. The first tooth 16 on the first gear wheel 10 to engage with the second gear wheel 14 (following the missing teeth section 12) is resiliently movable inwardly within a radial slot 18 to withdraw when engaging an opposing tooth 22. A spring 20 urges the tooth 16 outwardly to one side of the opposing tooth 22 and into a gap on that side of the opposing tooth 22, so as to align the first and second gear wheels. Such a gear arrangement has particular use in a geared value setting mechanism provided on a print drum shaft of a postage meter.

An electrical impulse operated number wheel counter with coaxial number wheels (2); transfer pinions (8); a reciprocable pawl (12) engaging the first number wheel and a solenoid (20) driving the pawl, has a series of leaf springs (33) carried on the solenoid armature (24). In the rest position the leaf springs (33) engage bosses (9) on the transfer pinions to ensure that the number wheels (2) are correctly aligned but when the solenoid (20) is energised to effect a count, the movement of the armature (24) lifts the leaf springs away from the transfer pinions (8) which can therefore rotate unhindered. An additional effect of the leaf springs is to reduce the power consumption of the counter and this effect can still be achieved with other spring arrangements. A shock resistance element (50) is freely rotatably mounted in the path of the pawl (12) so as to be struck in the event of shock induced movement of the pawl, substantially to eliminate spurious shock induced counts.

An indexing mechanism comprising a body (10) mounted so as to be rotatable about an axis; means (3) for rotating said body about said axis; first cam means (9, 10) for displacing said body along said axis away from an axial rest position during rotation of said body in a first direction; biassing means (11) for restoring the body to its axial rest position on completion of a rotation or a predetermined portion thereof of the body; means (8a) for detecting the axial movement of the body when it is being restored to its axial rest position; and second cam means (2, 9) permitting said body to be rotated in a second direction opposite the first direction.

A bi-directional snap-action register mechanism for an odometer-type mechanical register display. The mechanism includes at lease one register display wheel (61) and a bi-directional cam (17) mounted coaxially along a common shaft (1) with the register display wheel. The bi-directional cam (17) engages a helical groove (15) formed along the shaft to allow lateral displacement of the bi-directional cam in a direction parallel to a rotational axis of the shaft (1). A pin (i4) is biased by a spring into contact with the bi-directional cam. Rotation of the shaft causes the bi-directional cam to be moved with respect to the pin. The cam abruptly rotates through a predetermined angular distance when the point of contact of the biased pin with the cam moved from a smooth portion to a step transition portion of the cam. The abrupt rotation of the cam is communicated to the register display wheel to cause a new display position to be moved into view.

Un compteur a roues a numeros est commande par des impulsions electriques et possede des roues a numeros coaxiales (2), des pignons de transfert (8), un linguet a mouvements alternatifs (12) engageant la premiere roue a numeros et un solenoide (20) entrainant le linguet, et possede une serie de ressort a lame (33) portes sur l'induit solenoidal (24). Dans la position de repos, les ressorts a lame (33) engagent des bossages (9) sur les pignons de transfert pour assurer que les roues a numeros (2) sont correctement alignees, mais lorsque le solenoide (20) est excite pour effectuer un comptage, le mouvement de l'induit (24) souleve les ressorts a lame en les eloignant des pignons de transfert (8) qui peuvent ainsi tourner librement. Un effet supplementaire des ressorts a lame est de reduire la consommation d'energie du compteur et cet effet peut aussi etre obtenu avec d'autres dispositifs a ressorts. Un element de resistance de choc (50) est monte en rotation libre dans le chemin du linguet (12) de maniere a ce qu'il soit heurte dans le cas d'un mouvement du linguet induit par un choc, essentiellement pour eliminer les faux comptages engendres par des chocs.

The invention relates to a meter that comprises a body (460), first and second rotary counting means (410, 420) assembled in said body (460), said first counting means (410) interacting with an actuation member (1430) upon each actuation, said first counting means (410) comprising interconnection means of said second counting member (420), the interconnection means being actuated every tenth actuation, the first counting means (410) being provided with a first portion of a peripheral edge (412) comprising counting indices and with first teeth, said second counting member (420) being provided with a second portion of a peripheral edge (422) comprising counting indices and with third teeth, said peripheral edge portions (412, 422) being radially coplanar and non-concentric, said counting members (410, 420) rotating about parallel and offset rotation axes, said counting members (410, 420) being urged into contact together at a point located at a common counting and/or display area.

The abrupt rotation of the cam is communicated to the register display wheel to cause a new display position to be moved into view.
