Ce dernier comporte des butees en no#mbre egal au nombre de frap- pes correspondant ä 1a longueur du cylin- dre et destinees ä coo-perer avec des organes darret manoeuvres au moyen de touche s. Las butees sont generalement constituees par des organes coulissant entre les dents d'un peigne ou d'un räteau dispose parallelement au cylin- dre et rendu solidaire du ahariot mobile. La mise en Position active et 1e retrait des butees peuvent etre effectues soit manuellement, soit automatiquement, par la manceuvre de touches. Ces tabulateurs ne donneat pass en- tiere satisfaotion, car ils necessitent un tra- vail tres soigne et precis dans 1a fabrication des butees et du räteau, afin d'eviter des jeux nuisibles ä la precision de la Position darret du chariot. En d'autres termes, les butees doivent etre guidees de fagon tres. pre- cise, iafin de coulisser parallelement ä elle@s- mAmes sann jeu et sann risque de coincement. Machirre to write with tabulator. All jaws ä. modern typewriters are equipped with a tabulator. The latter comprises stops in a number equal to the number of strikes corresponding to the length of the cylinder and intended to cooperate with stop members operated by means of key s. Las stops are generally constituted by members sliding between the teeth of a comb or a rake arranged parallel to the cylinder and made integral with the mobile carriage. The placing in the active position and the withdrawal of the stops can be carried out either manually or automatically, by operating the keys. These tabulators do not give entire satisfaction, because they require very careful and precise work in the manufacture of the stops and the rake, in order to avoid play harmful to the accuracy of the stop position of the carriage. In other words, the stops must be very guided. precise, in order to slide parallel to itself with no play and no risk of jamming.

La presente invention a. pour objet une machirre ä ecrire ä tabulateur, ce dernier com- portant un nombre de butees egal au nom- bre de frap:pes eorrespondant ä la longueur du cylindre et destinees ä cooperer avec des organes darret mont'es sur la Partie fixe de la machirre, les butees etant portees par 1--in räteau dispose parallelement au cylindre et relie rigidement au chariot mobile, la mise en place et 1e retrait desdites butees etant command@s par des touches. The present invention has. the object of a typewriter with a tabulator, the latter comprising a number of stops equal to the number of strokes corresponding to the length of the cylinder and intended to cooperate with stop devices mounted on the fixed part of the machirre, the stops being carried by 1--in rake arranged parallel to the cylinder and rigidly connected to the movable carriage, the establishment and the first removal of said stops being controlled by keys.

Cette machirre tend ä eliminer 1'inconve nient cite par 1e fait que les butees sont cons tituees par -des organes basculants,, montes sur un axe commun"chaque organe bas-culant etant guide entre deux deute du räteau et saumis ä 1'action :d'un ress ort dispose dann 1e fond du gulde par lesdites dents, 1'organe basculant et 1e ressort etant conformes et disposes de maniere que 1'action du ressort Lende ä maintenir 1'organe basculant dann chacime des deux positions, extremes definies par 1'entree en Prise -d'une Partie de cet or organe avec une Partie du räteau. This machirre tends to eliminate the drawback cited by the fact that the stops are constituted by tilting members, mounted on a common axis, "each tilting member being guided between two blades of the rake and subjected to the action : of a spring disposed in the first bottom of the gulde by said teeth, the rocking member and the spring being in conformity and arranged so that the action of the Lende spring maintains the rocking member in each of the two positions, defined extremes by the entry into engagement of a part of this organ with a part of the rake.

Le dessin annexe montre, sch6matique ment et ä eitre d'exemple; une forme d'exe cution de la machirre faisant 1'objet de 1'in vention. The attached drawing shows, schematically and by way of example; a form of execution of the machirre forming the subject of the invention.

La fix. 1 est une vue en perspectzve du räteau partant et guidant les butees. The fix. 1 is a perspective view of the rake starting and guiding the stops.

La fix. 2 est une vue en coupe faite au travers dudit räteau: La fix. 3 est ime vue semblable ä la fix. 2, mais dans laquelle sont representes sch6ma tiquement les organes de commaude de la mise en place et du retrait des butees et des arrets. The fix. 2 is a sectional view taken through said rake: The fix. 3 is a view similar to the fix. 2, but in which are schematically represented the control bodies for the installation and removal of the stops and stops.

Le tabulateur de la machirre representee au dessin comparte un räteau 1 fixe rigide ment au chariot mobile c. Ce räteau est dis pose parallelement au cylindre r. Les dents 2 -de ce räteau forment entre elles un nombre de guides 3 egal au nombre de frappes oor respondant ä la longueur du cylindre. The tabulator of the machirre represented in the drawing compares a rake 1 fixed rigidly to the mobile carriage c. This rake is arranged parallel to the cylinder r. The teeth 2 of this rake form between them a number of guides 3 equal to the number of strikes corresponding to the length of the cylinder.

Dans chacun -de ces guides est logs un organe basculant 4, dont une Partie d'entre eux seulement est repr6sent6e. Tour ces or ganes ba=sculants 4 sont montes sur un age commun 6 fixe rigidement sur 1e räteau. Un ressort 5, constitue par une laure, est loge dans 1e fond des: guides B. Ces ressorts 5 pre sentent, ä;1'une ide leurs extremites, une Par tie recourbee 8 desbnee ä etre engag6e dans un logement 7 du räteau. In each of these guides is housed a tilting member 4, of which only a part of them is represented. In turn, these rocking bodies 4 are mounted on a common beam 6 fixed rigidly to the first rake. A spring 5, consisting of a laurel, is housed in the bottom of the guides B. These springs 5 present, at their ends, a curved part 8 designed to be engaged in a housing 7 of the rake.

Chaque organe basculant presente deux bras 10 et 11 et une gatte 12. Cette derniere esst destinee ä coop6rer avec 1e ressort 5, afin de znaintenir 1'.organe basoulant automatique ment dans chacune de ces deux positiöns eg tremes, dopt Tune est definie par fentree en Prise :d'une Partie :du bras 10 avec 1e fond du guide 3 et Pautre par 1'entr6e en Prise dune -Partie du bras 11 avec 1e fond du guide 3. Each tilting member has two arms 10 and 11 and a gate 12. The latter is intended to cooperate with the first spring 5, in order to keep the basing member automatically in each of these two positions, for example, one is defined by the window in Engagement: of a Part: of the arm 10 with the 1st bottom of the guide 3 and the other by the entry in Engaging of a -Part of the arm 11 with the 1st bottom of the guide 3.

Le bas.culement de ces orgänes de Tune de leurs positions extremes dans leur autre Posi tion extreme est commande au moyen de deux totiches 14, 15 de la machine. La touche 14 est reliee par des. organes de transmission ä un levier 16. pivot6 sur un.axe 17. L'extremit6 libre 18 de ce levier agit sur un oregane de commande 19 pivote sur un axe 20. Cet Or gane de commande presente un bec 21 destin6 ä deplacer angulairement forgane basiculant de sa Position @de retrait (Position indiquk en traits interrompus) jusque dans sa Posi tion- active ou de misse en place des cavaliers (Position indiquee, en traits pleins).- Des que la gatte 12 -a. subi un d6placement angulaire dune amplitude suffisante pour la faire pas ser sur 1e cöte oppose du plan perpendiculaire au ressort 5 et paissant par faxe 6, 1e ressort provoque automatiquement 1e basculement de l'organe 4 jusque ;dans. sa Position active (Po sition representde en traits pleins), et main tient Porgane 4 :dann cette Position active. Il en est,de meine lors du retrait de forgane 4. La touche 15 -est reli6e m6cäniquement par des Organes @<B>de</B> liaison ä un Organe d'action nement 22 pivote sur faxe 17 et comportant "un doigt 23 deshn6 ä actionner 1'organe bas- The bas.culement of these organs of Tune from their extreme positions to their other extreme position is controlled by means of two totiches 14, 15 of the machine. Key 14 is linked by dice. transmission members to a lever 16. pivoted on an axis 17. The free end 18 of this lever acts on a control member 19 pivoted on an axis 20. This control member has a beak 21 intended to move the member angularly basiculant of its Position @de withdrawal (Position indicated in broken lines) until in its Position- active or of installation of the jumpers (Position indicated, in full lines). - As soon as the gate 12 -a. suffered an angular d6placement dune amplitude sufficient to do not ser on the first side opposite the plane perpendicular to the spring 5 and grazing by fax 6, the first spring automatically causes the first tilting of the member 4 until; in. its Active Position (Po sition shown in solid lines), and hand is holding organ 4: in this Active Position.

Les organes basoulants, places en posi tion active, sont destines ä entrer en Prise avec un Organen darret 25, monte sur la Par tie fixe de la machine de maniere ä etre ,d@e plagable verticalement entre deux positions extremes. Cet org-ane darret est relie m6ca niquement ä une touche de commande 26 et est soumis ä 1'action d'un ressort tendant ä 1e maintenir .en Position eclipsee (Position re pr6sent6e ä la fix. 3). En pres s'ant sur la touche 26, fusager peut deplacer cet organe 25 vers 1e haut et placer son extremiM supe rieure sur 1e chemin du bras 11 d'un organe 4 place en Position active. The basoulant organs, placed in the active position, are intended to come into engagement with a stop organ 25 mounted on the fixed part of the machine so as to be vertically plagable between two extreme positions. This org-ane stop is mechanically connected to a control button 26 and is subjected to the action of a spring tending to maintain it .in the eclipsed position (Position represented at the fix. 3). By pressing the button 26, the fuser can move this member 25 upwards and place its upper extremity on the first path of the arm 11 of a member 4 placed in the active position.

Le fo.nctionnement de la maehine decrite est 1e suivant: La mise en Position active d'un organe basculant 4 est obtenue de la maniere sui vante: L'usager place premierement le chariot dann la Position longitudinale daus laquelle il Usire obtenir farret du chariot. Par ma noeuvre de la tou che 14, il piovoque 1e bascu lement de Vorgane 4 de sa Position repr6sen tee en traits interrompus jueque dann sa Po sition representee en traits pleins. Lorsque fusager @d6sire par la suite amener 1e chariot de droite ä gauche automatiquement dans la Position choisie, il lui ruffit alors d'agir sur une touche 26 reliee mkaniquement, dune Part, ä farret 25 et provoquant la mise en Position active de ce dernier (Position repre sentee ä la fix. 2) et, -d'autre- pari, au cliquet de retenue (non repr6sent6) et provoquant la lib6ration du ehariot. Ce dernier, Bons 1'ac tion de son ressort,de rappel, se deplace alors de droite ä gauche jusque dans une Position The operation of the machine described is as follows: The placing in active position of a tilting member 4 is obtained in the following manner: The user first places the carriage in the longitudinal position in which he uses to obtain the fart of the carriage . By my operation of key 14, it triggers the tilting of organ 4 from its Position represented in broken lines to its Position represented in solid lines. When the fuseger subsequently wishes to bring the carriage from right to left automatically into the chosen position, he then only has to act on a key 26 mechanically connected, on the one hand, to farret 25 and causing the latter to be placed in active position. (Position shown at fix. 2) and, -on the other hand, at the retaining pawl (not shown) and causing the release of the trolley. The latter, Good 1'action of its spring, return, then moves from right to left until in a Position

longitudinale definie par 1'entree en Prise de 1'arret 25 avec 1e -bras 11 de 1'organe 4. longitudinal defined by the entry into engagement of the stop 25 with the first arm 11 of the member 4.

La. mise en Position inactive d'un Organe 4 (Position reTresentee en traits interrompus) est abtenue en plaqant 1e chariot mobile dans une positian lon.gitudinale correspondant ä la Position dudit Organe 4, puis en agissant sur 1a, touche 15, afin de provoquer 1e bascu lement dudit Organe 4 de sa Position repre sentee en traits pleins jusque dans sa Posi tion representee en traits interrompus. The inactive position of a Body 4 (Position shown in dashed lines) is achieved by placing the mobile carriage in a longitudinal position corresponding to the Position of said Body 4, then by acting on 1a, key 15, in order to cause the first tilting of said member 4 from its position shown in solid lines to its position shown in broken lines.

Enfin, afin de permettre 1e retrait simul tane d'un nombre quelconque d'organes bas culants 4 en position active, un Organe d'a.c tionnement 27 est prevu. Ce dernier est cons t..itu6 par une pla,que 28 dont l'une des extre mit6s e.st recourbee, disposee parallelement au räteau et id'une lo@ngueur egale ä ce der nier. Cette Plaque 28 est fixee par un axe 29, pivote dans ]es parois laterales du cha riot mobile, et portant 1'organe de manceuvre 27 qui, maneeuvre dans 1e sens de la fleche F, provoque 1e retrait de tour les Organes 4. Finally, in order to allow the simultaneous withdrawal of any number of rocking bottom members 4 in the active position, an actuation member 27 is provided. This last is cons t..itu6 by a pla, that 28 of which one of the extrem mit6s e.st bent, placed parallel to the rake and id'une lo@ ngueur ega to this last deny. This Plate 28 is fixed by a pin 29, pivots in] the side walls of the mobile carriage, and carrying the maneuvering organ 27 which, maneuvering in the first direction of the arrow F, causes the Organs 4 to withdraw from their turn.

De ce qui precede et de 1'examen du des sin, an voit que, gräace au fait que les Orga nes 4 sont basoulants et montes sur un axe, leur guidage est beaucoup plus aise ä realiser et leur fonetionnement plus sür que lorsque, comme dann les machirres connues, ces Orga nes executent un mouvement de translation. En effet, aucun risque de coincement n'est ä craindre. From what precedes and from examination of the drawing, it can be seen that, thanks to the fact that the Organs 4 are basoulant and mounted on an axis, their guidance is much easier to achieve and their operation more sure than when, as in the known jaws, these Organs execute a translational movement. Indeed, no risk of jamming is to be feared.

De plus, les positions desdits Organes sont nettement definies et ils sont maintenus dann chazune de leurs positions (active et de re- trait) par 1'action d'un simple ressort plat pla:ce dans 1e f ond des rainures du räteau. Furthermore, the positions of said Organs are clearly defined and they are maintained in each of their positions (active and withdrawn) by the action of a simple flat spring placed in the bottom of the grooves of the rake.
