Uppfinnare: C. A. Johansson. Inventor: C. A. Johansson.

Foreliggande uppfinning hfinfOr sig till raknemaskiner, kassaregister och dylikl for utfOrande av sayal additions- som suhtraktionsoperationer. The present invention relates to razors, cash registers and the like for performing both addition and subtraction operations.

Uppfinningen har till andamal att vasentligt forenkla maskiner ay denna typ och samtidigt gra dem sakrare i drift. Speciellt skola enligt uppfinningen organen for gfingartomstallningen forenklas och farbilligas. The object of the invention is to substantially simplify machines of this type and at the same time make them safer in operation. In particular, according to the invention, the means for finger conversion are simplified and approved.

Uppfinningen hanfor sig salunda till en anordning yid raknemaskiner, kassaregister och dylikt med ett eller flera rakneyerk, manoyrerhara till tva eller flera gangarter (t. ex. addition, subtraktion, sub-total och totalsummatagning, non-addition etc.) under kontroll ay ett forskjutbart huyudskiftorgan, pa vilket ett antal av gangartstangenter installbara skiftarmar aro yridbart lagrade och forskjuthara tillsammans med huyudskiftorganet, som fir fOrskjutbart till tya. (eller flera) olika lagen under inyerkan ay en medbringare pa maskinens huvutdaxel eller en darav driyen axel. Uppfinningen kannetecknas 1 huyudsak ay att endast tva skiftarmar aro direkt paverkbara av tie gangartstangenter, under det att andra ay skiftarmarna aro anordnade att payerkas ay flagon eller nagra av de En' gfingartstangenterna direkt payerkbara skiftarmarna. The invention thus relates to a device for razors, cash registers and the like with one or more rake machines, maneuverers for two or more gaits (eg addition, subtraction, sub-total and total sum taking, non-addition, etc.) under the control of a displaceable height-shifting means, on which a number of gait keys installable shift arms are movably mounted and displaceable together with the high-displacement means, which is displaceable to tya. (or more) different layers under the inner shaft on a carrier on the main shaft of the machine or one of which is a rotating shaft. The invention is mainly characterized in that only two shift arms are directly actuated by ten gear keys, while other ay shift arms are arranged to be mounted on the flag or some of the finger keys directly payable by the shift arms.

The machine Or shown in the drawing is hand-driven, in that for each raking operation the lever 11 mounted on the main shaft 10 (Figs. 3 and 4 is manually imparted a reciprocating oscillating movement. However, the machine can of course also be set motor-driven p0 UM.

Tangentbord. Keyboard.

Den pa ritningen visade maskinen Or utford sasom en tiotangentmaskin med tio sif- fertangenter, markta '09 (fig. 4). I tangent- bordet finnas dessutom ftiljande tangenter: Subtraktionstangent 12 markt SUBTRACT Sub-totaltangent eller transportsummatan,ient 13 markt SUBTOT Totaltangent eller slutsummatanuent 14 markt TOT Non-additionstangent 15 markt NON-ADD Backslagstangent 16 markt BACKSPACE Repetitionstangent 17 markt REPT Korrektionstangent 18 markt CORRECTION Installningsverk. The machine shown in the drawing Or challenges as a ten-key machine with ten number keys, marked '09 (fig. 4). The keyboard also has the following keys: Subtraction key 12 markt SUBTRACT Sub-total key or transport sum, ient 13 markt SUBTOT Total key or sum sum key 14 markt TOT Non-addition key 15 markt NON-ADD Reverse key 16 markt BACKSPACE Repetition key .

Pa siffertangenterna 0-9 Oro stift 20 (fig. 2) fasta, vilka verka direkt p0 vinkelhavstanger 21, som Oro vridbart lagrade kring de fas- — —:3 ta tapparna 22 i maskinstativet (namligen monteringsplatarna 26). Siffertangenten 0 verkar med sin nedre ande direkt pa den tillhorande vinkelhavstangen 21. Dessa vinkelhdystanger 21 aro medelst tappar 23 ledbart forkmdna med skjutstanger 24. Tangenterna aro genom tapp- och sparfOrband vid 25 styrda till ratlinig vertikalrorelse. Skjutstangerna aro belastade av dragfjadrar 27, som tjana till att aterfora respektive tangent, sedan operatOren slappt den med fingret, och am fOrskjutbara i slitsar i en stationar styrplat 28. Denn.a Sr medelst skruvarna 29 fast pa vinkelstycket 30 pa maskinens bottenplatta. Fixed on the number keys 0-9 Oro pins 20 (fig. 2), which act directly on angular sea rods 21, which Oro rotatably mounted around the phase pins 22 in the machine frame (namely the mounting plates 26). The number key 0 acts with its lower spirit directly on the associated angular sea rod 21. These angular height rods 21 are articulated by means of pins 23 with push rods 24. The keys are by pin and spare connections at 25 guided to rectilinear vertical movement. The push rods are loaded by tension springs 27, which serve to return the respective key, after the operator has released it with the finger, and are displaceable in slots in a stationary guide plate 28. This is fixed by means of the screws 29 on the elbow 30 on the bottom plate of the machine.

Nar flagon av siffertangenterna 0-8 nedtryckes, forskjutes alltsa motsvarande skint-slang 24 bakat (at hoger i fig. 2) och verkar darigenom direkt pa motsvarande stoppstift (stallstycke) 31 i en vagn 32 (fig. 1), varvid dock nedtryckningen av siffertangenten 9 har icke flagon inverkan pa stoppstiften 31, endr de mot siffertangenten 9 svarande stoppstiften aro utelamnade. Siffertangenten 9 motsvaras i stallet av ett langsgaende fast aiming 33 pa vagnen 32. When the flag of the number keys 0-8 is pressed, the corresponding leather hose 24 is displaced backwards (to the right in Fig. 2) and thereby acts directly on the corresponding stop pin (stable piece) 31 in a carriage 32 (Fig. 1), whereby, however, the pressing of the number key 9 does not have a slight effect on the stop pins 31, otherwise the stop pins corresponding to the number key 9 are omitted. The numeric key 9 corresponds instead to a longitudinal fixed aiming 33 on the carriage 32.

Denim vagn 32 med stoppstiften 31 samvertar pa i och for sig kant salt med 'typstanger 35 rasp. med till dessa typstanger kopplade kuggstanger 34, som hejclas av det eller de framtryckta stoppstiften 31 (rcsp. av det motsvarande fasta anslaget 33, nar siffertangenten 9 nedtryckts 1 motsvarande decimal-position). En detaljeracl beskrivning av denna kanda mekanism är overflodig; det fordo vara tillrackligt att namna, att de i vertikalled rorliga kuggstangerna 34 pinta de pit dem rorligt anbragta typstangerna 35 (for tryckning av beloppen) dragas uppat i lyftfjadrar (dragfjadrar) 36 for att hejdas av stoppstiften 31 eller anslaget 33. Varje typstang 35 dr vridbart lagrad pa motsvarande kuggstang 34 inedelst en tapp 37 °eh fastpinnen 38 for den nedre anden av fjadern 36 ligger p5 sidan om denna tapp. Detta medfor, att fjadern 36 stravar icke blott att lyfta typstangen 35 uppat utan Sven att -vrida den riktning bort Iran tryckvalsen 39. Denim trolley 32 with stop pins 31 converges on per se edge salt with 'type rods 35 rasp. with toothed rods 34 connected to these type rods, which are hoisted by the pre-pressed stop pin 31 (rcsp. of the corresponding fixed stop 33, when the numeric key 9 is pressed in the corresponding decimal position). A detailed description of this kanda mechanism is superfluous; it should be sufficient to mention that the vertically movable racks 34 pinta de pit the movably mounted type rods 35 (for printing the amounts) are pulled upwards in lifting springs (tension springs) 36 to be stopped by the stop pins 31 or the stop 33. Each type rod 35 dr. rotatably mounted on the corresponding rack 34 inside a pin 37 ° and the fixed pin 38 for the lower end of the spring 36 lies on the side of this pin. This means that the spring 36 not only strains to lift the type rod 35 upwards but Sven to turn that direction away from the pressure roller 39.

De for ingrepp med kuggstangerna 81 avsedda rakneverkshjulen 40 aro lagrade pa en axel 411 sidogavlar 42 (fig. 3 och 6), som i sin tar aro svangbart lagrade kring en stational. axel 43 (fig. 2 och 3), som Sr fast i de for hela rakneverksgruppens sammanfogning avsedda, med varandra stelt forbundn,a sidogavlarna 44 (fig. 3 och 5). Rakneverkshjulen 40 arc forsedda med var sin tiooverfOringstand 45 (fig. 6 och 8) pa den ena (vanstra) sidan av hjulet; spetsen av tiooverforingstanden 45 befinner sig (sett i axelns 41 riktning) mitt emellan tvenne kuggar pa rakneverkshjulet 40. The razor wheels 40 intended for engagement with the racks 81 are mounted on a shaft 411 side ends 42 (Figs. 3 and 6), which in turn are pivotally mounted around a station. axis 43 (Figs. 2 and 3), which is fixed in the side gables 44 (Figs. 3 and 5) intended for the joining of the whole rake network group, interconnected. The rake network wheels 40 are provided with their respective ten-position tooth 45 (Figs. 6 and 8) on one (left) side of the wheel; the tip of the ten transmission tooth 45 is located (seen in the direction of the shaft 41) midway between two teeth on the rake wheel 40.

Sidogavlarna 42 aro fast forbundna med varandra genom de mellan gavlarna anbragta slitsade styrplatarna 46, 47, 48, 49, 50 (se speciellt fig. 2). I slitsarna i styrplaten 46 aro tiooverforingsutlosarna 51 styrda pa sadant satt, att de komma mitt for rotationsplanet for motsvarande tiooverfOringstand 45; dessa utlosare aro vridbart lagrade kring den i gaylarna 44 fasta axeln 52 (fig. 2 och 8). Fjadrar 53 draga tiooverforingsutlosarna 51 moturs till anliggning mot bottnen av de ovre styrsparen i styrplaten 46, sa att spetsen eller tanden 54 pa utlosaren 51 normalt befinner sig pa liimpligt avstand fran rakneverkshjulens centrum. Nar en tiooverforingstand 45 under en riikneoperation passerar (roterar) forbi en tioOverforingsutltisares 51 tand 54 (se fig. 2, 7 och 8), vrider tanden 45 denna utlosare 51 at hager (medurs) sh lSngL att utlosarens nedre ombockade ande eller utsprang 55 gripes och fastlases av den kring axeln vridbart lagrade sparrarmen 56; denna Sr fOrsedd med ett hak 57 och belastad av en dragfjader 58, sO. alt vid den nyss namnda vridningen av utlosaren 51 medurs haket 57 snapper in pa sidan cm (bakom) utspranget 55. Sparrarmarna 56 aro i axiell led styrda slitsar i styrplatarna 49, 50. Nar en tiotalsutlOsare p5 detta salt vridits medurs och sparrats av sin sparrarm 56, Sr en tiooverforing forberedd vid den ifragavarande decimalpositionen. The side ends 42 are fixedly connected to each other by the slotted guide plates 46, 47, 48, 49, 50 arranged between the ends (see especially Fig. 2). In the slots in the guide plate 46, the ten transfer triggers 51 are controlled in such a way that they come in the middle of the plane of rotation of the corresponding ten transfer position 45; these triggers are rotatably mounted about the shaft 52 fixed in the gills 44 (Figs. 2 and 8). Springs 53 pull the ten transmission triggers 51 counterclockwise to abut against the bottom of the upper guide pairs in the guide plate 46, so that the tip or tooth 54 of the trigger 51 is normally at a reasonable distance from the center of the rake wheels. When a ten-transmission tooth 45 during a straightening operation passes (rotates) past the tooth 54 of a ten-transfer trigger 51 (see Figs. 2, 7 and 8), the tooth 45 rotates this trigger 51 so as to move clockwise so that the lower bent spirit or protrusion 55 of the trigger is gripped. and is secured by the pivot arm 56 rotatably mounted about the shaft; this Sr is provided with a hook 57 and loaded by a tension spring 58, sO. alt at the just mentioned rotation of the trigger 51 clockwise the hook 57 snaps in on the side cm (behind) the projection 55. The ratchet arms 56 are axially guided slots in the guide plates 49, 50. When a tens trigger on this salt is rotated clockwise and sparred by its ratchet arm 56, Sr a ten transfer prepared at the decimal position in question.

En fOrberedd liaverfOring fullbordas forst, nar rakneverkshjulen 40 foras Over till ingrepp med kuggsektorerna 59 (fig. 7), som arc vridbart lagrade pa den stationara axeln 60, vilken är fast mellan gavlarna 44. liuggsektorn 59a for entalskugghjulet 40a (fig. 6) kan dock icke vrida sig kring axeln 60, eniir en ombockad del (flik) 61 pa denna kuggsektor 59a ingar i en urtagning i sidogaveln 44; kuggsektorn 59a hair darfor icke till uppgift att fullborda flagon tiooverforing, vilket ju icke !can she till entalshjulet 40a, utan endast att astadkomma lagesbestamning for detta hjul, d. v. s. att hada delta hjul i riktigt vinkellage fOr korrekt ingrepp med kuggarna motsvarande installningskuggstang 34. A prepared transmission is completed only when the razor wheels 40 are brought over to engage the gear sectors 59 (Fig. 7), which are rotatably mounted on the stationary shaft 60, which is fixed between the ends 44. The bearing sector 59a of the singular gear 40a (Fig. 6) can however, do not rotate about the shaft 60, a bent part (tab) 61 on this tooth sector 59a engages in a recess in the side end 44; the gear sector 59a does not, therefore, have the task of completing the flap tenover transmission, which of course it can not to the singular wheel 40a, but only to provide a legal determination for this wheel, i.e. to have the wheels in the correct angular position for correct engagement with the teeth corresponding to the installation rack 34.

I fig. 7 visas kuggsektorerna 59 i sina neutrallagen (vilolagen), van i de kvarhallas av var sin motsvarande kuggsektorsparr 62, som da med sin ovre ombockade del eller utsprang 63 ingriper i ett mittspar 64 i en i kuggsektorn 59 anordnad urtagning 65 under laverkan av dragfjadern 66. Varje sparr 62 Sr svangbar i samma plan som motsvarande hoOverforingsutlOsare 51. Nar darfor en utlosare 51 ph ovan angivet satt svanges medurs av tioOverforingstanden 45 for fOrberedande av en tiooverforing, kommer denna utlosare under den fortsatta maskingimgen, nar rakneverkshjulen 40 frikopplas fran kuggstangerna 34 och overforas till ingrepp med motsvarande kuggsektor 59, att sla an mot sparren 62, sit att aven denim svanges medurs (i fig. 5, 4- - 7 och 8) och harigenom dess utsprang 63 frikopplas fran mittsparet 64 i kuggsektorn 59. Fig. 7 shows the gear sectors 59 in their neutral laws (rest laws), accustomed to being retained by their respective gear sector rafters 62, which then with their upper bent part or projections 63 engage in a central pair 64 in a recess 65 arranged in the tooth sector 59 during the lowering of the tension spring 66. Each ratchet 62 is pivotable in the same plane as the corresponding head transmission trigger 51. Therefore, when a trigger 51 ph above set is pivoted clockwise by the ten transmission gear 45 to prepare for a ten transmission, this trigger comes during the continued machine turning when the rake tool wheels 40 the racks 34 and are transferred to engagement with the corresponding gear sector 59, to strike against the ratchet 62, so that the denim is also pivoted clockwise (in Figs. 5, 4-7 and 8) and thereby its projections 63 are disengaged from the center pair 64 in the gear sector 59.

Det kanske sarskilt bar papekas, att nar rakneverkshjulen 40 jamte tiooverforingsutlosarna frikopplas fran kuggstangerna 34 och foras over till ingrepp med kuggsektorerna 59, de ay tiooyerforingsutlosarna 51, som icke payerkas (svangts) av tioaverforingstanderna 45, icke ná fram till sparrarna 62 utan himna dessa sparrar opayerkade i deras laslage. I de decimalpositioner, diir flagon tioaverforing icke forbereas, slier salunda heller icke flagon tioaverforing (savida icke under sjalva tiooverforingens fullbordande till MIN ax en da utford tiooyerforing i en lagre decimalposition en ny tiooyerforing fiirberedes och fullbordas i en hogre dechnalposition). It was perhaps especially noteworthy that when the rake wheels 40 and the ten transmission triggers are disengaged from the racks 34 and passed over to engage the gear sectors 59, the other transmission gears 51, which are not paid (swung) by the ten transmission gears 45, do not reach the rafters 62. opayerkade in their laslage. Thus, in the decimal positions where the thioferposition is not prepared, the phaglio is not slipped either (except during the completion of the thiotransfertion itself to MY axis, then a thioureability in a lower decimal position is prepared and completed in a higher dechnal position).

Det fir att obseryera, att yisserligen -Hooverforingsutlosarna 51 am svangbara i samma plan som motsvarande sparrar 62, meii att den till en sadan utlosare 51 harande kuggsektorsparren 62 med sitt utsprang 63 ingriper i och samverkar med kuggsektorn 59 for narmast hagre decimalposition, alltsa med den nfirmast till yfinster (fig. 3) om kuggsektorsparren 62 befintliga kuggsektorn 59. Varje tiooverforingsutlosare 51 kommer, Mir den syanges ay tiooyerforingstanden 43 for en -kiss decimalposition salunda att frigbra kuggsektorn 59 for Mirmast hOgre decimalposition. Urtagningen 65 i vane kuggsektor 59 an sa star, att den genom anslag mot utspranget 63 pa sparrarmen 62 begransar tiooverforingsrorelsen (yridningsyinkeln) has kuggsektorn till en kuggdelning I additiv riktning respektiye en kuggdelning i subtraktiv riktning, raknat fran mittsparet 64. It is to be noted that the main transfer triggers 51 are pivotable in the same plane as the corresponding rafters 62, in that the gear sector latch 62 having such a trigger 51 engages with its projection 63 and cooperates with the gear sector 59 for the nearest decimal position, i.e. with the nfirmast to yfinster (fig. 3) about the gear sector spar 62 existing gear sector 59. Each ten-transfer trigger 51 will, Mir den syanges ay tiooyerforingstanden 43 for a -kiss decimal position salunda to free the gear sector 59 for Mirmast hOgre decimal position. The recess 65 in the usual tooth sector 59 states that, by abutment against the projection 63 on the spar arm 62, it delimits the tenover transfer movement (rotation angle) if the tooth sector has a tooth pitch in the additive direction or a tooth pitch in the subtractive direction, straight from the center pair 64.

De organ, som astadkomma den for tioaverforingen erforderliga -yridningen ay kuggsektorerna 59, urn visade t. ex. i fig. 5, 7 och 9. The means which provide the ride required for the transmission in the gear sectors 59 are shown e.g. in Figs. 5, 7 and 9.

Varje spar 75 ligger i samma, mot omkopplingsaxeln 68 vinkelrata plan som det tillhorande armparet 76 och motsvarande utsprang 78. Dragfjadrarna 77 tjana saledes dels till att kyarhalla armarna 76 i sparen dels till att hiilla dessa armor fran hada sidor mot utsprangen 78 pa kuggsektorerna 59, .sa att kuggsektorerna medbringas (vridas), nar armarna 76 yridas. In bearing bushings 67 (Fig. 3), which are fixedly connected to the side ends 44, a switching shaft 68 parallel to the rake iron shaft 41 is mounted (Figs. 3, 5, 7, 9). At the ends of this shaft, two arms 69 are rigidly fastened, which support an Indian string 70 attached to them. At the right end of the switch shaft 68, a disc 71 (Figs. 3 and 18) is fixed by a pin 72 passing through the shaft. This disc carries two pins 73, 74. Peripheral grooves 73 (Fig. 7) are suspended in the switching shaft 68, in which armor 78 (Figs. 3, 5, 7, 9) are loaded the load of the pair; these armor are cut out on their side edges facing each other in a circular manner, so that they all fit against the switching shaft 68. Between the two pairs of arms 76 there is a tension spring 77 bucket, which presses the free tips 76 to abut against the upwardly projecting projections. 78 pfl gear sectors 59. Each groove 75 lies in the same plane perpendicular to the switching axis 68 as the associated pair of arms 76 and corresponding projections 78. The tension springs 77 thus serve partly to keep the arms 76 in the grooves partly to keep these arms from having sides towards the projections 78 on the gear sectors 59, .sa that the gear sectors are brought (rotated) when the arms 76 are rotated.

The curry pair 81 is so designed that when the main axis 10 with the curve ski 80 is in-bearing wear in Fig. 19 shown, the haystang 83 is located in the lower layer and the length 79 is lowered, which means that the switching pin 68 via the arms 76 carries the extended tooth sectors 59 after completion of the lining to their central layer (middle layer), -rani de anyo lasas ay the spiers 63 , which snap into the middle pairs 64 and read the gear sectors 59 until the next ten-year experience is performed.

Den oyan beskriyna tioiiverforingen fir den vid additionsoperationer utferda. Vid subtraktion bringas daremot rakneyerkshjulen 40 i ingrepp med kuggstangerna 34 redan under forsta delen ax vridningsrorelsen has huvudaxeln 10 och forbliva i ingrepp under kuggstangernas lyftningsrorelser. Emellertid pa, borjas Oxen under samma tidsmoment Ater- — — foringen av omkopplingsaxeln 68 till dess i fig. 7 visade neutrallage.

For detta andamal ãr pa den i sidogavlarna 42 vridbart lagrade axeln 88 en bygel 89 fast. Bygeln stracker sig i axiell led tvars over samtliga kuggsektorer 59 och svangas till ingrepp med de pa kuggsektorernas baksidor (hogra sidor i fig. 2, 5, 7, 9, 10, 20, 22) forefintliga tapparna eller tanderna 90 av dragfjadern 91, sedan lasningen av bygeln upphavts. For detta andamal Or pa huvudaxeln 10 en (Oven for tryckningen avsedd) kamskiva 92 (fig. 3 och 25) fast nara utsidan av den vanstra gaveln 93. Pa denna kamskiva Or en tapp 92a fast, vilken verkar pa den ovanfor befintliga vinkelhavstangen 94, nar kamskivan roterar.

SO snart som spetsen 103a (fig. 10) av armen 103 till foljd, av den nyss namnda motursvridningen av sparrarmen 99 glider av ansatsen 99a ph denna sparrarm, drages bygeln 89, som genom ett nay Or stelt forbunden med armen 103, av sin fjader 91 till ingrepp med utsprangen 90 pa kuggsektorerna 59. Aterforing av armen 103 .och. bygeln 89 sker medelst vinkelhavstangen 104, som med ett utbockat utsprang 105 in-griper i ett spar i armen 103. Vinkelhavstangen 104 aterfores av tappen 200 (fig. 1 och 15) skiftarmen 111. The oyan describes the thiollivering for that performed in addition operations. In subtraction, on the other hand, the rake wheels 40 are brought into engagement with the racks 34 already during the first part of the rotational movement of the main shaft 10 and remain engaged during the lifting movements of the racks. However, at the same time, the Taurus begins the retraction of the switching shaft 68 to its neutral position shown in Fig. 7. For all that, the gear sectors 59 should not cancel (turn back) the (additive) thiotransferences that are necessary in the next preceding rake operation, as is necessary, because these gear sectors are initially loaded. For this purpose, a bracket 89 is rotatably mounted on the shaft 88 rotatably mounted in the side ends 42. The stirrup extends in the axial direction across all the tooth sectors 59 and is pivoted into engagement with the pins or teeth 90 of the tension spring 91 present on the rear sides of the tooth sectors (right sides in Figs. 2, 5, 7, 9, 10, 20, 22), then the lasing of the jumper was originated. For this purpose, a cam plate 92 (Figs. 3 and 25) (Figs. 3 and 25) (fixed for printing) is fixed near the outside of the left end cap 93. On this cam plate a pin 92a is fixed, which acts on the angular sea rod 94 above, when the cam disc rotates. If the main shaft 10 jam-Le this cam disc rotates the angle a (Fig. 25) Iran the starting layer, the angular sea rod 94 is lifted, which Or is rotatably mounted around the pin 95 on one end of the arm 96, the other dude Or fixed on the shaft 88. The second arm of the sea rod 94 projecting to the left in Figs. 25 (and 11) abuts against the underside of a pin 97. The lifting action of the pin 92a on the angle sea rod 94 thus produces one. rotation of the shaft 88, and this rotational movement ceases at the moment when the arm abutting the pin 92a on the left-hand rod 94 is pushed so far to the right that the engagement on the pin 92a ceases due to the counteracting action of the pin 97 on it. other arm of the same angle sea rod. The arm 98 (Fig. 10) fixed to the opposite end of the shaft 88 thereby affects the spar arm 99, which is rotatably mounted around the pin 100; this pin Or stationary fixed ph angle plate 86 (Fig. 3). As a result, the ratchet arm 99 pivots to the left (counterclockwise) in Fig. 10 against the action of the tensioning spring 101 clamped between the ratchet arm and a fixed pin 102. The pin 102 is fixed on the right-hand end 93 (Fig. 3). As soon as the tip 103a (Fig. 10) of the arm 103 is followed, by the just mentioned counter-rotation of the ratchet arm 99 sliding off the shoulder 99a ph this ratchet arm, the stirrup 89, which is rigidly connected to the arm 103 by a spring, is pulled by its spring 91 to engage the projections 90 on the tooth sectors 59. Retraction of the arm 103 .and. the jumper 89 takes place by means of the angular sea rod 104, which with a bent-out projection 105 engages in a groove in the arm 103. The angular sea rod 104 is returned by the pin 200 (Figs. 1 and 15) to the shift arm 111.

Den ovan namnda vridningsrorelsen hos axeln 88 utnyttjas Oven shsom aterforingsroraise for de tiooverforingsutlosare 51, som pa ovan beskrivet salt sparrats i forberett lage far tiooverfOring enligt fig. 8. For detta anda mai Or en bygel 106 (fig. 2 och 9) vridbart upphangd pa de pa axeln 88 fasta armarna 107. Den nedre, horisontala delen av denna by-gel stracker sig under samtliga sparrar 56. DO axeln 88 med armarna 107 svanges pa nyss angivet satt, lyfter alltsa bygeln 106 upp samtliga sparrar 56, sa aft tiooverforingsullosarna 51 frigoras och aterforas till sina vilolagen 53. Harvid fir bygeln 106 styrd i vertikalled av spar i ett stationart stod 108 (fig. 2 och 8). En fjader 109 (fig. 11 och 25) gerfor vinkelhavstangen 94 och armen 96 till deras i fig. 11 visade utgangslagen till anliggning mot den stationara (ph vanstra gaveln 93 i fig. 3 anbragta) stopptappen 110. The above-mentioned rotational movement of the shaft 88 is also used as a feedback rotaise for the ten-transfer triggers 51, which on the salt described above are sparred in the prepared layer for ten-point transmission according to Fig. 8. For this spirit, a stirrup 106 (Figs. 2 and 9) may be rotatably suspended on the arms 107 fixed to the shaft 88. The lower, horizontal part of this stirrup extends below all the rafters 56. DO the shaft 88 with the arms 107 is pivoted in the manner just indicated, thus the stirrup 106 lifts up all the rafters 56, so that the ten transfer loops 51 is released and returned to its resting layers 53. At this point the stirrup 106 guided in the vertical direction by tracks in a stationary type stood 108 (Figs. 2 and 8). A spring 109 (Figs. 11 and 25) connects the angular sea rod 94 and the arm 96 to their starting layers shown in Fig. 11 for abutment against the stationary (ph left end end 93 in Fig. 3) stop pin 110.

The main shift means 111 and the shift arms 112, 113, 114 (Figs. 5-7, 11-48) in the shift mechanism are movable (rotatable) relative to each other, but at the same time constitute a cohesive unit which receives displacement movement of the carrier 115 fixed on the main shaft 10. 112, 113, 114 Concerns rotatably mounted on the pin 129 fixed on the main arm 111. In its normal position, i.e. when none of the gait keys 12-15 are depressed and the machine is thus installed for addition, the shift arm 113 is located. with its rear (hogra in Figs. 5-7 and 11-18) tip against the ph main arm 111 fixed pin 130 under the influence of the tension spring 131, which Or spanned between the 6 - arms 111 and 113. An Indian arms 111 and 112 spanned tension spring 132 holds the arm 112 in the normal layer (for addition). Furthermore, the arm 114 is connected to the arm 112 by the tension spring 133 which is spun between them, which pulls the arm 114 with its rear (hogra in Fig. 5) formed to a spike 114a abut against the ninth pin 134 next to the ph arm 112. In the arm 111 In an elongate groove 135 is received, which encloses the pin 136 fixed on the stationary frame 30. In its second dude, the arm 111 is guided on the shaft 10 for rectilinear movement. Furthermore, two hooks 137 are accommodated on the underside of the arm 111, which co-operate with the stationary spring rafter 138, which thus serves to releasably retain this arm in its outer layer.

For enkelhets skull ma antagas, att talet »9» redan hr inregistrerat i rakneverket (40) och att daretter siffertangenten 2 intryckts fOr att talet »2» skull inforas i rakneverket. Hdrvid kommer alltsa en tiooverforing att aga rum. For additionsoperationen f8r operatoren spaken 11 fram och Ater i den sedvanliga vaggningsrorelsen. Under framatrorelsen av denim spak sker pa vanligt satt lyftning av kuggstangerna 34 (medan rakneverkshjulen 40 aro frikopplade darifran). Ndr sedan spaken 11 anyo fOres bakat och harigenom huyudaxeln 10 yrides medurs, star den pa derma axel fasta medbringaren 115 riled sin ombockade spets 115a an mot haket 113b pa skiftarmen 113 (fig. 7), varigenom denna arm 113 och harigenom iiven huvudskiftorganet 111 medbringas ratlinigt bakat (at hoger i fig. 7) en stracka L, som hr lika med avstandet mellan de hada 'taken 137, innan ingreppet mellan niimnda delar 115a och 113h upphor, vilket sker i det moment, som ãr visat i fig. 7. Under denim ingreppstid %rider sig axeln 10 en yinkel 13' medurs (fig. 7). Den vid huvudskiftorganet 111 fasta tappen 119 forflyttas harvid strackan L och genom silt ingrepp i kurvsparet 118 vrider den salunda armen 116, som darvid OverfOr yridningsr5relsen till axeln 117 (fig. 5 och 12), armarna 120, 121, axeln 122, Iankarna 125, 126 och tapparna 127, 128 och harigenom till rakneverkets sidogavlar 42, vilka upphara de pa axeln 41 lagrade rakneverkshjulen 40. Dessa konnua salunda nu i ingrepp med kuggstangerna 34, innan dessa aterforas nedat yid maskingan gen. The machine performs an addition operation when none of the gait keys 12-15 have been pressed and therefore the main shift member 111 and the shift arms 112, 113, 114 assume their normal laws. For the sake of simplicity, it must be assumed that the number »9» is already registered in the rake (40) and that the number key 2 is then pressed for the number »2» to be entered in the rake. In this case, a ten transfer will take place. For the addition operation, the operator moves the lever 11 forward and Ater in the usual rocking motion. During the forward movement of the denim lever, the racks 34 are normally lifted (while the razor wheels 40 are disengaged therefrom). When the lever 11 is then moved backwards and through which the huyud shaft 10 is rotated clockwise, the carrier 115 fixed on this shaft rests its bent tip 115a against the hook 113b on the shift arm 113 (Fig. 7), whereby this arm 113 and thereby the main shift member 111 are carried rectilinearly baked (at right in Fig. 7) a distance L, which is equal to the distance between the hada 'roofs 137, before the engagement between said parts 115a and 113h ceases, which takes place in the moment shown in Fig. 7. During denim engagement time%, the shaft 10 rides an angle 13 'clockwise (Fig. 7). The pin 119 fixed to the main shift member 111 is then moved the distance L and by silt engagement with the cam pair 118 rotates the salunda arm 116, which thereby transmits the sliding movement to the shaft 117 (Figs. 5 and 12), the arms 120, 121, the shaft 122, the anchors 125, 126 and the pins 127, 128 and thereby to the side gables 42 of the razor, which terminate the rake wheels 40 mounted on the shaft 41. These can now be engaged with the racks 34, before they are returned downwards to the machine.

Vid den fortsatta vridningsrorelsen hos huvudaxeln 10 fOrskjutes nu entalskuggstangen 34 nedat de tva steg, somn den blivit upplyft. Entalsrakneyerkshjulet 40a vrides alltsd en vinkel, motsvarande tva kuggdelningar, da ju enligt antagandet talet »2» skall adderas till det pa detta hjul redan registrerade talet »9». Ella" ju harvid en tioOyerforing skall ske, passerar tiooverforingstanden 45 forbi spetsen 54 pa tioOverforingsutlosaren 51, som darvid pa ovan angivet salt svanges ut och lases i silt i fig. 8 visade lage (forberedd tiooverforing). TiooverfOringen hr salunda nu registrerad i tiooverforingsutlosaren 51 for ental; overforingen av densamma till 'limeverkets tiotalshjul (alltsa rakneverkshjulet i Mirmast hogre decimalposition) sker under den fortsatta widningen av huvudaxeln 10. Harvid frikopplas namligen rakneverkshjulen 40 frau kuggstangerna 34 och aterforas till sitt utgangslage. Detta sker genom att den andra ombockade linden (utspranget) 115h pa medbringaren 115 stiller emot det utbockade utspranget 111a pit huvudskiftorganet 111, sa att delta at erfores (strackan L) framat (at vanster i fig. 7) och harigenom rdkneverkshjulen 40 aterforas till ingrepp med kuggsektorerna 59 via de nyss beskrivna kopplingsanordningarna (119, 118, 116, 117, 120-122, 125-128, 42). Tiooverforingen fullbordas, ndr tiooverforingsutlosaren 51 Hied sin bakre kant stater emot den dartill horande sparren 62 och pressar ut derma ur mittsparet 64, sa att pa ovan beskrivet slat den nu frigjorda kuggsektorn 59 -vrides i additiv riktning (medurs 1 fig. 7) ett steg under inverkan av fjaderns 77 tryck pa kuggsektorutspranget 78. With the continued rotational movement of the main shaft 10, the singular rack 34 is now displaced down the two steps as it has been raised. The entalsrakneyerkshjuler 40a is thus turned an angle, corresponding to two tooth divisions, since according to the assumption the number «2» must be added to the number already registered on this wheel «9». Otherwise, in the case of a ten-transfer, the ten-transfer tooth 45 passes the tip 54 of the ten-transfer trigger 51, which is then swung out on the salt indicated above and read in silt shown in Fig. 8 (prepared ten-transfer). The ten-transfer is now registered in the ten-transfer release 51. For the singular, the transfer of it to the lime wheel's decimal wheel (i.e. the razor wheel in Mirmast's higher decimal position) takes place during the continued widening of the main shaft 10. Namely, the razor wheel 40 is disengaged from the racks 34 and returned to its starting position. the protrusion 115h on the carrier 115 abuts the bent-out protrusion 111a of the main shift member 111, so as to participate in the forward (distance L) forward (left in Fig. 7) and thereby return the redneck wheels 40 to engagement with the gear sectors 59 via the coupling devices just described ( 119, 118, 116, 117, 120-122, 125-128, 42) .Tiooverforingen fullbor das, ndr tiooverforingsutlosaren 51 Hied sin rear edge states against the associated raft 62 and pushes it out of the middle pair 64, so that on the above described beat the now released tooth sector 59 -turned in additive direction (clockwise 1 fig. 7) one step below the effect of the spring 77 pressure on the gear sector projection 78.

Sub-total- och totalsummatangenternas lasning. Reading the sub-total and total sum keys.

Vid den beskrivna maskinen ar det noclvandigt att Ora ett sarskilt slag i tomgang med manOverspaken 11, innan subtotalsummatangenten 13 eller totalsummatangenten 14 kan nedtryckas. Nat- en additions-, subtraktionseller non-additionsoperation utforts, (d. v. s. efter det att nagon av siffertangenterna 0-9 blivit nedtryckt), forbliva alltsa tangenterna 13 och 14 lasta, tills lasningen upphaves genom tomgangsslaget. Rent principiellt ãr anordningen av detta slag i -tomgang icke nodvandigt, men bar liar likyal denna anordning vaIts for ernaende av en saker funktion. Mekanismen for lasning av dessa tangenter 13, 14 liar stallts i beroende av stoppstiftvagnens 32 lage, &Isom framgar av fig. 1: Pa den stationdra (vid bottenplattan 87 fasta) monteringsgaveln 139 for gangartstangenterna 12-14 är en sparrskena 140 forskjutbart lagrad under dessa tangenter och i samma plan som dessa. Skenan 140 tjanar till att lasa de hada summatangenterna 13, 14. De pa gaveln 139 fasta stiften 142 ingä i avlanga spar 141 i denna sparrskena, som harigenom styres till en ratlinig horisontalrorelse. Vid den bakre (hogra i fig. 1) anden av skenan 140 hr en tapp 143 fast, kring 'vii-ken lanken 144 or vridbart lagrad. Denim -- - lank -vrides av en dragfjader 145 till anliggfling (underifran) mot platen 146 pa stoppstilts- eller siffervagnen 32. En klack eller ett utsprang 147 ph lanken 144 ligger harvid an mot den ombockade kanten av platen 146 och skenan 140 Mlles salunda i sitt i fig. 1 visade vanstra andlage, i vilket summatannee terna 13 och 14 aro fria och kunna nedtryckas. Om nu flagon av siffertangenterna 0-9 nedtryckes och till f8ljd harav siffervagnen 32 sidoforskjutes (at va.nster i maskinen), drages skenan 140 ur ingrepp med klacken 147 och fjadern 145 drager nu skenan 140 bakat (at hoger i fig. 1), sã att de uppskjutande klackarna pa derma skena komma rakt under tangenterna 13, 14 och dessa foljaktligen icke kunna nedtryckas. Dessa tangenter kunna sedan frigoras endast genom ett extra tomgangsslag med spaken 11, sasom ovan namnts. Harvid vrides namligen den pa en stationar tapp 148 vridbart lagrade havarmen 149, i det att denna hay-arms ovre del pfiverkas av kanten av kamskivan 80 (fig. 21), ndr denna roterar. Ndr salunda havarmen 149 svanges medurs i fig. 1, forskjuter den nedre anden av derma arm lanken 144 framat (at vanster i fig. 1), tills klacken 147 anyo snapper in under platen 146 och sparrskenan 140 hdrigenom lases i sitt vanstra lage i fig. 1, sa att tangenterna 13, 14 ater bliva fria. In the described machine, it is necessary to perform a special stroke at idle with the control lever 11, before the subtotal sum key 13 or the total sum key 14 can be pressed. If an addition, subtraction or non-addition operation is performed (i.e., after any of the number keys 0-9 have been pressed), the keys 13 and 14 will remain loaded until the loading is started by the idle stroke. In principle, the device of this kind is not necessarily necessary, but only if this device is chosen for the purpose of a function. The mechanism for loading these keys 13, 14 is set depending on the position of the stop pin carriage 32, & As shown in Fig. 1: On the stationary (fixed to the bottom plate 87) mounting end 139 for the gait keys 12-14, a ratchet rail 140 is slidably mounted under these keys. and in the same plane as these. The rail 140 serves to read the hot sum keys 13, 14. The pins 142 fixed on the end 139 are included in elongate grooves 141 in this ratchet rail, which is thereby guided to a rectilinear horizontal movement. At the rear (right in Fig. 1) spirit of the rail 140 hr a pin 143 is fixed, around the viiken ken 144 or rotatably mounted. Denim - - lank - is twisted by a tension spring 145 to abut (from below) against the plate 146 on the stop or number carriage 32. A lug or a projection 147 ph the lank 144 rests against the folded edge of the plate 146 and the rail 140 Mlles salunda in its left-hand base shown in Fig. 1, in which the sum units 13 and 14 are free and can be depressed. If now the flake of the number keys 0-9 is pressed and as a result the number carriage 32 is displaced laterally (at the left in the machine), the rail 140 is pulled out of engagement with the lug 147 and the spring 145 now pulls the rail 140 backwards (to the right in Fig. 1). so that the projecting lugs on this rail come directly below the keys 13, 14 and consequently these cannot be depressed. These keys can then be released only by an extra idle stroke with the lever 11, as mentioned above. Namely, the sea arm 149 rotatably mounted on a stationary pin 148 is rotated, in that the upper part of this hay arm is actuated by the edge of the cam disc 80 (Fig. 21), when it rotates. Thus, when the sea arm 149 is pivoted clockwise in Fig. 1, the lower end of this arm displaces the tongue 144 forward (at left in Fig. 1), until the lug 147 snaps under the plate 146 and the ratchet 140 is thereby read in its left bearing in Figs. 1, said that the keys 13, 14 become free again.

For laming .av gangartstangenterna 12, 13, 14, 15 i nedtryckt lage are lasskenor 150, 151 (fig. 1, 11, 23) anordnade i samma plan som respektive tangenter och forsedda med lastander 153 mitt for dessa tangenter (men daremot icke vid tangenterna 16, 17). Dessa lasskenor aro forsedda med avlanga spar, i -vilka de stationara tapparna 142, 154 inga, sa att dessa skenor aro forskjutbara i sin langdriktning (horisontalt). Skenorna 150, 151 aro hopkopplade till gemensam forskjutningsrarelse medelst tva armar 155, 156, som are ledbart forbundna med dessa skenor och stelt forbundna medelst en axel 157, vilken är vridbart lagrad I maskinstativet (mellan gaylarna 139 och 158, fig. 241. Armen 156 är paverkad av en dragfjader 159 (fig. 23). Gangartstangenterna 12, 13, 14, 15 aro forsedda med utsprang eller lastander 12a, 13a, 14a, 15a, for samverkan med lastanderna 153. Vid nedtryckning av en av dess tangenter snappar motsvarande lastand 153 pa simian 150 eller 151 in Over tangentens lastand under inverkan av fjadern 159, sa att tangenten lases i nedtryckt age. Om harvid tidigare an .annan gangartstangent varit nedtryckt, utloses den pa. kant ,satt och fares upp till slit vilolage igen under inverkan av sin tangentfja.der 160. For paralysis of the gait keys 12, 13, 14, 15 in depressed lower load rails 150, 151 (Figs. 1, 11, 23) arranged in the same plane as the respective keys and provided with load stands 153 opposite these keys (but not at keys 16, 17). These welding rails are provided with elongate grooves, in which the stationary pins 142, 154 do not, so that these rails are displaceable in their longitudinal direction (horizontally). The rails 150, 151 are connected to a common displacement movement by means of two arms 155, 156, which are hingedly connected to these rails and rigidly connected by means of a shaft 157, which is rotatably mounted in the machine frame (between the girders 139 and 158, Fig. 241. The arm 156 is actuated by a tension spring 159 (Fig. 23) The gait keys 12, 13, 14, 15 are provided with projections or load teeth 12a, 13a, 14a, 15a, for co-operation with the load teeth 153. When depressing one of its keys, the corresponding load tooth snaps 153 pa simian 150 or 151 in Over the key's load position under the action of the spring 159, so that the key is read in depressed age.If in the case of another gait key has been depressed, it is released on the edge, sat and driven up to worn rest position again under the impact of its tangent feather.der 160.

Totalsummatagning. Total sum taking.

For denna operation nedtryckes totalsummatangenten 24 och lases pa nyss angivet satt i nedtryckt lage, sasom visas i fig. 11. Pa tangenten 14 ãr en tapp 161 fast, som vid tangentens nedtryckning medbringar shiftarmen 114 nedat. Mot slutet av nedtryckningsrorelsen slar tappen 161 an. mot skiftarmen 113, som dock vrider endast en liten vinkel. Harigenom fores spetsen 114a pa skiftarmen 114 nagot moturs och denna skiftarm medbringar nu i sin fur skiftarmen 112 moturs via fjadern 133. Fjadern 133 dr starkare (har langre hdyarm) an fjadern 132. Harigenom lyftes den bakre (i fig. 11 hogra) ändeu av armen 112, sa att utspranget 112a pa denna arm fores fran sitt normallage uppat till ingrepp med utspranget 115b pa medbringaren 115. Skiftarmen 112 sviinges harvid av fjadern 133 moturs, tills denna skiftarm med sin ovre kant star an mot utspranget 111a pa huvudskiftorganet 111. For this operation, the total sum key 24 is depressed and is read in the manner just indicated in the depressed position, as shown in Fig. 11. On the key 14 a pin 161 is fixed, which when the key is pressed brings the shift arm 114 down. Towards the end of the depression movement, the pin 161 strikes. against the shift arm 113, which, however, rotates only a small angle. As a result, the tip 114a of the shift arm 114 is moved slightly counterclockwise and this shift arm now carries in its fur shift arm 112 counterclockwise via the spring 133. The spring 133 pulls stronger (has a longer right arm) than the spring 132. This lifts the rear (in Fig. 11 right) end of the arm 112, so that the projection 112a on this arm is moved from its normal position upwards to engage with the projection 115b on the carrier 115. The shift arm 112 is then swung counterclockwise by the spring 133, until this shift arm with its upper edge abuts the projection 111a on the main shift member 111.

Nar nu huvaclaxeln 10 vrides vinkeln 19 moturs i fig. 18, fo5rskjutes organet 111 strackan L i sin langdriktning (horisontalt bakat), enar utspranget 115b vid medbringarens 115 vridning slar an mot utspranget 112a pa skiftarmen 112, sá att hela skiftarmsgruppen f Orskjutes bakat (at hager i fig. 11) till den position, som framgar av fig. 13. Under den fortsatta vridningsrorelsen hos huvudaxeln 10 moturs stoter utspranget 115a pa medbringaren 115 mot spetsen 113a pa skiftarmen 113, sa att skiftarmsgruppen ffirskjutes strackan L tillbaka till sitt utgangslage, medan lut- Tudaxeln vrider sig vinkelnfig. 7 och 13. When the hood shaft 10 is now turned the angle 19 counterclockwise in Fig. 18, the member 111 is displaced the distance L in its longitudinal direction (horizontally baked), the projection 115b at the rotation of the carrier 115 strikes the projection 112a on the shift arm 112, so that the whole shift arm group f at hooks in Fig. 11) to the position shown in Fig. 13. During the continued rotational movement of the main shaft 10 counterclockwise, the projection 115a of the carrier 115 abuts against the tip 113a of the shift arm 113, so that the shift arm group moves the distance L back to its initial position, while the tilt- Tudaxel rotates angularly fig. 7 and 13.

Enar vid nedtryckning av totalsumnaatangenten endast en liten vridning av skiftarmen 113 astadkommits, befinner sig spetsen 113b av denna skiftarm utanfor rotationsbanan av utspranget 115a pa medbringaren 115. Nar medbringaren 115 svanges tillbaka medurs under returvridningsrorelsen (fig. 14) hos huvudaxeln 10, verkar dadar lake under vinkeln utspranget 115a pa skiftarmsgruppen. Ddremot befinner sig vid denna returvridningsrorelse (vinkeln fl fig. 13) spetsen 112a pa skiftarmen 112 i rotationsbanan for utspranget 115b, varfor skiftarmen 112 fjadrar undan for utspranget 115b, enar ju denna arm är fjddrande forbunden med den mot tappen 134 anliggande skiftarmen 114. Once only a slight rotation of the shift arm 113 has been achieved by depressing the total sum key, the tip 113b of this shift arm is outside the path of rotation of the projection 115a on the driver 115. When the driver 115 is pivoted back clockwise during the return rotation movement (Fig. 14) of the main shaft 10, at an angle protruding 115a on the shift arm group. On the other hand, in this return rotation movement (the angle in Fig. 13), the tip 112a of the shift arm 112 is in the path of rotation of the projection 115b, so that the shift arm 112 springs away from the projection 115b, since this arm is resiliently connected to the shift arm 114 abutting the pin 134.

Under denna fram- och atergaende forskjutningsrorelse hos huvudskiftorganet 111 och skiftarmarna 112-114 forflyttas den pa huvudskiftorganet 111 fasta tappen 119 (fig. 5) i kurvsparet 118. Harigenom hringas rak- neverkshjulen 40 i resp. ur ingrepp med kuggstangerna 34 pa ovan beskrivet satt. (Se analog forflyttning under rubriken addition). Totalsummatagningstangenten 14 ar aven fOrsedd med ett ombockat utspring 162 (fig. 4, 11 och 12), som vid tangentens nedtryck- ning verkar pa armen 163, vilken dr fast pa den ena (hogra) anden av den i maskinstati- vet vridbart lagrade axeln 164. Pa denna .axels andra (vanstra) dude är en arm 165 fast, 'vil- 8— — ken Overt'Or den genom tangentens nedtryckning astadkomna vridningsrorelsen till en trearmad havstang 166. Denna bar i ytteranden av sin framre (i fig. 11 vanstra) arm ett op-pet spar, som omsluter en tapp 167 pa armen 165 och ãr vridbart lagrad pa den stationara tappen 168. Den bakre (i fig. 11 hOgra) armen 166a av denna havstang verkar med sin spets pa undersidan av den framat (at vans-ter i fig. 11 och 12) utskjutande delen av nollagesvaggan 169, som ãr vridbart lagrad pa en axel 170, yilken ãr fast i stoppstiftsvagnen 32. Denna vagga tjanar till att lhsa de kuggstanger 34 i deras nedersta lage (nolllage), for vilka wagon siffertangent icke blivit intryckt. Nar armen 166a vrides moturs i fig. 11, svanger den undan nollagesvaggan 169 fran dess kuggstangerna 34 sparrande lage. Den vertikalt uppskjutande armen 166b (fig. 11, 12) pa havstangen 166 är ledbart forbunden med lanken 171, sout är styrd i sidled av ett spar i den stationfira styrplaten 172 och drages nedat mot bottnen av detta spar. Nar totalsummatangenten 14 nedtryckes, fOrskjutes sitlunda lanken 171 framat (= at vanster i fig. 11, 12 och 25) frau det I fig. 25 visade laget till det hige, som är vi-sat i fig. 11. Den bakre delen (spetsen) 171a pa denna lank shipper sitt stodlage mot overkanten av haken 174 och drages nedat mot bottnen i sparet i styrplaten 172. Haken 174 ar vridbart lagrad ph den stationara (1 gavein 93 fasta) tappen 175 och är belastad av dragfjadern 176, som trycker haken till anliggning mot ett stationart stift 177. Fjadern 176 är spand mellan haken 174 och en arm 178, som är fast pa axeln 122 och vilar mot knaggen 171b pa oversidan av lanken 171, oeh denna fjader tjanar saledes iiven till att hahn lanken 171 trycht mot bottnen av sparet i styrningen 172. Nar pa detta salt liinken 171 forskjutes till foljd av nedtryckningen av totalsummatangenten 14, svanges alltsh armen 178 och damned aven axeln 122. Pa denna axel ar en bygel 179 fast (intill och mellan armarna 120, 121) och vid den nyssnamnda svangningen av axeln 122 vrides denna bygel (moturs i fig. 11) till ett sadant att bygelns med axeln 122 parallella del faller ned till ett lage nagot nedanfor de oversta spetsarna av tiooverforingsutlosarna 51. During this reciprocating displacement movement of the main shift member 111 and the shift arms 112-114, the pin 119 (Fig. 5) fixed to the main shift member 111 is moved in the cam pair 118. As a result, the razor gear wheels 40 are rotated in resp. out of engagement with the racks 34 in the manner described above. (See analog transfer under the heading addition). The total summing key 14 is also provided with a bent-out projection 162 (Figs. 4, 11 and 12), which upon pressing the key acts on the arm 163, which is fixed to one (right) end of the shaft rotatably mounted in the machine frame. 164. On the second (left) dude of this shaft is an arm 165 fixed, 'which- 8— - ken Overt'Or the torsional movement brought about by the pressure of the key to a three-armed sea rod 166. This bore in the outer edge of its front (in fig. 11 left) arm an open recess, which encloses a pin 167 on the arm 165 and is rotatably mounted on the stationary pin 168. The rear (in Fig. 11 right) arm 166a of this sea rod acts with its tip on the underside of the forward (at the left in Figs. 11 and 12) projecting the portion of the zero bearing cradle 169, which is rotatably mounted on a shaft 170, which is fixed in the stop pin carriage 32. This cradle serves to loosen the racks 34 in their lower bearing (zero bearing). ), for which the wagon number key has not been pressed. When the arm 166a is rotated counterclockwise in Fig. 11, it pivots away from the zero bearing cradle 169 from its rack 34. The vertically projecting arm 166b (Figs. 11, 12) on the sea rod 166 is hingedly connected to the line 171, soot is guided laterally by a groove in the stationary guide plate 172 and is pulled down towards the bottom of this groove. When the total sum key 14 is depressed, the string 171 is displaced forward (= left in Figs. 11, 12 and 25) from the layer shown in Fig. 25 to the hige shown in Fig. 11. The rear part (tip) ) 171a on this link shifts its strut against the upper edge of the hook 174 and is pulled down towards the bottom of the groove in the guide plate 172. The hook 174 is rotatably mounted on the stationary (1 gavein 93 fixed) pin 175 and is loaded by the tension spring 176, which presses the hook for abutment against a stationary pin 177. The spring 176 is clamped between the hook 174 and an arm 178, which is fixed to the shaft 122 and rests against the hook 171b on the upper side of the link 171, and this spring thus serves to push the link 171. the bottom of the groove in the guide 172. When on this salt the link 171 is displaced as a result of the depression of the total sum key 14, the whole arm 178 is pivoted and down also the shaft 122. On this shaft a bracket 179 is fixed (next to and between the arms 120, 121) and at the newly named In the pivoting of the shaft 122, this stirrup (counterclockwise in Fig. 11) is rotated to such an extent that the part of the stirrup parallel to the shaft 122 falls down to a position slightly below the uppermost tips of the ten transfer triggers 51.

Fig. 11 och 13 visa bygeht 179 i det lage, som densamma intager vid totalsummatagning, alltsa sedan tangenten 14 nedtryckts. Bygelns med axeln 122 parallella del ligger da lagre An och bakom tiooverforingsutlosarnas 51 owe spetsar och hindrar alltsa dessa frau att svangas baliat (medurs). Figs. 11 and 13 show buoyancy 179 in the position which it occupies when taking a total sum, i.e. after the key 14 has been pressed. The parallel part of the yoke with the shaft 122 then lies on the bearing An and behind the owe tips of the ten transfer triggers 51 and thus prevents these women from being swung baliat (clockwise).

Yid totalsummatagning bringas alltsa re-don vid borjan av maskingangen rakneverkshjulen 40 i ingrepp med kuggstangerna 34, innan dessa borja lyftas. Lyftfjadern 36 lyfter nu respektive kuggstangs- och typstlingsaggregat 34, 35 uppat, tills tiooverforingstan den 45 hos det med kuggstimgen hopkoppIade rakneverkshjulet 40 sliir an mot och stop-pas av spetsen 54 pa motsvarande flayed& ringsutlosare 51, som ju lasts i sitt vilolage av bygeln 179, redan vid nedtryckning av tangenten 14. Typstangerna 35 komma alltsa att stoppas i det hojdlage, som motsvarar det i respektive ralmeverkshjul registrerade beloppet och totalsummabeloppet tryckes nu ph kant satt, kuggstangerna 34 frikopplas Iran de nu nollstallda rakneverkshjulen 40 och aterforas till sina vilolagen (nedersta lagen). I den sista delen av returvridningsrorelsen has huvudaxeln 10 erhaller axeln 157 pa kant salt en kortvarig vridningsrorelse (rnoturs i fig. 1 och 11), sa att armarna 150, 151 forskjutas framtit (= at vanster i fig. 1 och 11) och harigenom den nedtryckta gangartstangenten (t. ex. 14) utloses och upplyftes av sin fjader 160. Thus, in total summing, at the beginning of the machine entrance, the razor wheels 40 are brought into engagement with the racks 34, before these begin to be lifted. The lifting spring 36 now lifts the respective rack and pinion assembly 34, 35 upwards, until the transmission of the 45 of the rack-coupled rake wheel 40 slides against and is stopped by the tip 54 of the corresponding flattening trigger 51, which is loaded in its rest position 17 by the jumper 17. , already when the key 14 is pressed down. The type rods 35 will thus be stopped in the height position corresponding to the amount registered in the respective frame wheel and the total amount is now pressed ph edge set, the gear rods 34 are disengaged from the now zeroed razor wheels 40 and returned to their rest layers. layers). In the last part of the return rotation movement, the main shaft 10 has the shaft 157 on the edge salt a short rotation rotation (rotation in Figs. 1 and 11), so that the arms 150, 151 are displaced forward (= to the left in Figs. 1 and 11) and thereby the the depressed gait key (eg 14) is released and lifted by its spring 160.

Efter slutford totalsummatagning livarstiir bygeln 179 i sitt nedre, tiooverforingsutlosarna 51 Ihsande lage och maste dad& f8re nasta additions- eller subtraktionsoperation Ater-Bras till sitt (upplyfta) Ifige, i vilket den lainnar tiooverfi5ringsutlosarna 51 trio (se t. ex. fig. 5). Detta sker vid nasta maskingang -enom Milken 171. After the final sum total, the jumper 179 lives in its lower, ten-transfer triggers 51, which is lowered and must carry the next addition or subtraction operation Ater-Bras to its (raised) Ifige, in which it loosens the ten-transfer triggers 51 trio (see, e.g., Fig. 5) . This takes place at the next machine entrance - via Milken 171.

Sasom ovan beskrivits, erhaller under huvudaxelns 10 vridningsrorelse -vinkeln a yinkelhavstangen 94 en hojningsrorelse (lyftes av tappen 92a, fig. 25). Nar totalsummatangenten 14 utloses och atergar till sitt utgangslage, aterfores aven Milken 171 at hoger i fig. 11, sa att dess nedatriktade, ombockade hogra ande 171c kommer att befinna sig raht Over vinkelhaystiingens 94 ovre del 94a. Nar vinkelhavstangen 94 salunda lyftes, kommer den att medbringa den hogra (bakre) Auden av lanken 171 uppht, sa all sparrhaken 174 under inverkan av sin fjader 176 snapper in Over spetsen 171a pa denna lank, som alltsa lases i detta lage. As described above, during the rotational movement of the main shaft 10, the angle α of the angular sea rod 94 receives a rising motion (lifted by the pin 92a, Fig. 25). When the total sum key 14 is released and returns to its initial position, the Milken 171 is also returned to the right in Fig. 11, so that its downward, folded right 171c will be located directly above the upper part 94a of the angle lift 94. When the angle sea rod 94 is thus lifted, it will bring the right (rear) Auden of the line 171 up, so that all the ratchet 174 under the influence of its spring 176 snaps in over the tip 171a of this line, which is thus read in this layer.

Transportsummatagning (subtotal). Transport sum taking (subtotal).

Nar transportsumma- eller subtotaltangenten 13 nedtryckes, blir verkningssattet VAsenthigen detsamma, som ovan beskrivits under rubriken totalsummatagning. Emellertid verkar vid nedtryckningen av tangenten 13 den darpa anbragta tappen 180 pa en upphojd del eller ham 181 pa skiftarmen 113 (fig. 15), som harigenom vrides moturs kring tappen 129. Detta inedfOr, att spetsen 113a pa armen lyftes sA myeket, att den gar fri for utspranget 115a pit medbringaren 115, nar derma vrides, sasom visas i fig. 16. Nar sedan huvudaxeln 10 atergar till sitt vilolage, slier salunda aterforingen av skiftorgangruppen 111-114 under vinkeln g i fig. 16. Under den fram- och atergiende vridningsrorelsen hos huvudaxeln 10, komma salunda rakneverkshjulen i ingrepp med kuggstangerna 34 vid saval dessas hojningsrorelse som de- — --9 ras sankningsrorelse. Tryckning av transportsumman sker, nar kuggstangerna 34 stannat vid slutet av htijningsrorelsen, och under sankningsrorelsen aterforas rakneverkshjulen 40 till sina utgangslagen, sa att efter transportsummatagningen det registrerade be1oppet star kvar i rakneverket. When the transport sum or subtotal key 13 is depressed, the effect set is substantially the same as described above under the heading total sum taking. However, when the key 13 is depressed, the tapered pin 180 acts on a raised part or shaft 181 on the shift arm 113 (Fig. 15), which thereby rotates counterclockwise around the pin 129. This means that the tip 113a of the arm is raised so much that it When the main shaft 10 returns to its resting position, the return of the shift member group 111-114 slides at the angle given in Fig. 16. During the forward and return direction, when the main shaft 10 returns to its resting position, the return shaft of the shift member group 111-114 slides. the rotational movement of the main shaft 10, the razor wheels thus come into engagement with the racks 34 at both their raising movement and their lowering movement. Pressing of the transport sum takes place when the racks 34 have stopped at the end of the hoisting movement, and during the lowering movement the razor wheels 40 are returned to their initial positions, so that after the transport sum collection the registered amount remains in the rake.

Subtraktion. Subtraction.

Vid nedtryckning av subtraktionstangenten 12 verkar den pa denna fasta tappen 182 (fig. 17 och 18) pa skiftarmarna 113, 114, sa att dessa relativt medbringaren 115 intaga samma lagen, som de fa efter intryckning av totalsummatangenten 14 (se ovan under rubriken totalsummatagning). When the subtraction key 12 is pressed, it acts on this fixed pin 182 (Figs. 17 and 18) on the shift arms 113, 114, so that these relative to the carrier 115 assume the same law as the few after pressing the total sum key 14 (see above under the heading total sum taking) .

Vid subtraktion skall ju tiooverforingen ske negativ riktning, alltsa i motsatt riktning mot additionstiooverforingen. For att astadkomma detta är pa subtraktionstangenten 12 annu en tapp 183 (fig. 1 och 11) anbragt, som vid nedtryckningen av denna tangent vrider -vinkelhaystangen 184 moturs mot verkan av den pa derma arm arbetande dragfjadern 185. Vinkelhavstangen fir vridbart lagrad pa den stationara tappen 180 (som är fast pa. gavel. 139) och med vinkelhavstangen är den ena anden av en lankarm 187 ledbart fOrbunden. Den motsatta anden av denna lankarm är forsedd med ett avlangt spar, vari en tapp 188 pa lanken 79 ingar. Mellan donna tapp och en pinne 189 pa lankarmen 187 Or en dragfjader 190 spand, som normalt hailer tap-pen 188 i anliggning med den yanstra (framre) anden av sparet i lankarmen 187, sasom visas i fig. 1. Fjadern 185 hailer nor-malt, alltsa nar subtraktionstangenten 12 icke Or nedtryckt, lankarmen 187 i doss bakre (1 fig. 1 hOgra) lage, i vilket sparet 79a i den Ovre anden av lanken 79 musluter-tappen 73. Nar nu subtraktionstangenten nedtryckes och lases i ncdtryckt lage (genom att sparren 153 snapper in Over utsnranget 12a, fig. 1), komma delarna att intaga de lagen, som visas i fig. 17. (Delarna visas alltsa i fig. 17 i de ',igen, solid de intaga often nedtryckning av subtraktionstangenten men fore maskingangens borjan, alltsa innan vridningen av huvudaxeln 10 borjat). Nar harvid lankarmen 187 drages at va.nster i fig. 17 (framat i maskinen), spannes fjadern 190 ytterligare. SOsom tidigare beskrivits, erhaller Milken 79 under maskingangen en upp- och nedgaende fOrskjutningsrorelse frau kurvskivan 80 (fig. 19). In the case of subtraction, the ten transfer must take place in a negative direction, ie in the opposite direction to the addition ten transfer. To achieve this, a pin 183 (Figs. 1 and 11) is arranged on the subtraction key 12, which, when this key is depressed, rotates the angle lift rod 184 counterclockwise against the action of the tension spring 185 acting on it. The angle sea rod is rotatably mounted on the stationary the pin 180 (which is fixed to the gable 139) and with the angular sea rod one of the ends of a long arm 187 is hingedly connected. The opposite spirit of this long arm is provided with an elongate groove, in which a pin 188 on the long arm 79 ings. Between the donna pin and a pin 189 on the long arm 187 Or a tension spring 190 bucket, which normally holds the pin 188 in abutment with the left (front) spirit of the groove in the long arm 187, as shown in Fig. 1. The spring 185 hails nor- malt, that is, when the subtraction key 12 is not Or depressed, the lane arm 187 in the doss rear (1 fig. 1 hOgra) layer, in which the spare 79a in the upper end of the lane 79 musluter-pin 73. When now the subtraction key is pressed and read in the pressed position ( by the ratchet 153 snapping in. Over the nozzle 12a, Fig. 1), the parts will occupy the layers shown in Fig. 17. (The parts are thus shown in Fig. 17 in the ', again, solid they often take depression of the subtraction key but before the beginning of the machine entrance, i.e. before the rotation of the main shaft 10 has begun). When the long arm 187 is pulled to the left in Fig. 17 (forward in the machine), the spring 190 is further tensioned. As previously described, Milken 79 receives an upward and downward displacement movement from the cam disk 80 during the machine entrance (Fig. 19).

Den nedatgaende forskjutningsrorelsen paborjas, sedan huvudaxeln 10 vridit sig vinkeln och has fullbordats efter ungefar halva den framatgliende (moturs) vridningsr5- relsen hos derma huvudaxel alltsa efter vinkeln ô i fig. 19. I detta ogonblick hat. omkopplingsaxeln 68 ungefar natt sitt neutrallage (i vilket tapparna 73, 74 ha sina centrumlinjer i samma horisontalplan) och fjadern 190 kan darfor nu draga Milken 79 at vans-ter (moturs) i fig. 17, sa att tappen 74 kommar in i och tappen 73 lamnar sparet 79a. Den uppatgaende rorelsen has lanken 79 bOrjar sa gott som omedelbart efter det att bottenlaget uppnatts och pagar under vinkeln a'. Detta tidsmornent Or avsett for overforing av rakneverkshjulen 40 till deras hogra (bakre maskinen) lage i fig. 22, som visar delarnas Jägen efter fullbordad tioOverforing. I detta Nigro_ lage Oro ju rakneverkshjulen 40 i ingrepp med kuggsektorerna 59. Harvid utfores tiaverfOringen pa analogt satt som vid en additionsoperation (se ovan under rubriken addition), men i negativ (subtraktiv) riktfling, beroende p0 att omkopplingsaxeln 68 vrides i motsatt riktning (medurs) mot forlidllandet rid addition, enar tappen 74 och icke tappen 73 Or i ingrepp med sparet 79a i Milken 79 under dennas rorelse uppat. (Sedan gar axeln 10 vinkeln y', tills den nar vandningspunkten). Vid ittergangen passeras vinklarna y', (5', 6, 7 i ornvand ordning. The downward displacement movement is started after the main shaft 10 has turned the angle and has been completed after about half the forward (counterclockwise) rotational movement of this main shaft, i.e. according to the angle δ in Fig. 19. At this moment hat. the switching shaft 68 approximately at night has its neutral bearing (in which the pins 73, 74 have their center lines in the same horizontal plane) and the spring 190 can therefore now pull the Milken 79 to the left (counterclockwise) in Fig. 17, so that the pin 74 enters and the pin 73 leaves the save 79a. The upward movement has the length 79 begins almost immediately after the bottom layer has been reached and pag at the angle a '. This time is Or intended for transferring the razor wheels 40 to their hogra (rear machine) bearing in Fig. 22, which shows the Jägen of the parts after completed tenTransmission. In this Nigro_lage Oro the razor wheels 40 engage with the gear sectors 59. In this case the transmission is carried out in an analogous manner as in an addition operation (see above under the heading addition), but in a negative (subtractive) direction, due to the shift shaft 68 being rotated in the opposite direction ( clockwise) towards the forearm rid addition, units the pin 74 and not the pin 73 Or in engagement with the spar 79a in the Milken 79 during its upward movement. (Then the axis 10 goes the angle y ', until it reaches the watering point). At the entrance, the angles y ', (5', 6, 7 are passed in the order of water.

Av fig. 20 och 22 framgar Oven Ifigena hos den rakneverkets omkoppling styrande skiftmekanismen. Sedan returvridningsrorelsen has huvudaxeln 10 fullbordats och darmed subtraktionstangenten 12 utlbsts och ntergatt till sitt vilolOge, kvarsta lanken 79, lankarna 187 och vinkelhaystangen 184 i sina loge. for subtraktion trots dragningen Iran fjadern 185, enar ju lanken 79 fortfarande stoder mot tappen 73, sasom visas i fig. 21. Delarna 79, 187 och 184 aterforas darfor av fjadern 185 fors.t rid nasta maskingang, nar man anyo farsatter manoverspaken 11 i rorelse. Nar rid derma nastfoljande maskingang lanken 79 anyo nOtL sitt bottenlage och ornkopplingsaxeln 08 sitt nentrallage (tapparna 73 och 74 ha sina centrumlinjer i samma horisontalplan), kan tappen 73g0 in i sparet 79. och delarna 79, 187, 184 aterfOras. Figures 20 and 22 show the Oven Ifigena of the switching mechanism controlling the switching mechanism. After the return rotation movement, the main shaft 10 has been completed and thus the subtraction key 12 is released and returned to its rest position, the remaining link 79, the links 187 and the angle high link 184 in its boxes. for subtraction despite the pull Iran spring 185, the unit 79 still stands against the pin 73, as shown in Fig. 21. Parts 79, 187 and 184 are therefore returned by the spring 185 fors.t ride the next machine entrance, when anyo maneuver the control lever 11 in rorelse. When riding the next machine entrance link 79 anyo nOtL its bottom bearing and the coupling shaft 08 its nentral bearing (pins 73 and 74 have their center lines in the same horizontal plane), pin 73g0 can enter the groove 79. and parts 79, 187, 184 can be returned.

Non-addition. Non-addition.

Nar non-additionstangerden 15 nedtryckes, skall det 1 tangentbordet inslagna beloppet (Wet) lake registreras I rakneverket. Rakneverksbjulen 40 forbliva dart& kopplade till kuggsektorerna 59, men dessa rakneverkshjul skola under huvudaxelns 1 fram- och atergaende vridningsrOrelse icke inkopplas till kuggstangerna 34 under dessas upplitoch nedatgaende rorelse. Detta astadkommes genom att rid nedtryckning av non-addtan. genten 15 denna trycker pa en arm 191 (fig 23, 24), som Or fast pa den ena anden av tvargiiende, I monteringsgavlarna 139, 158 yridbart lagrad axel 192. Med tangenten ett stilt 193 stelt fOrbundet, vilket Mika rid tangentens nedtryckning slar an mot airmen 191 och harigenom yrider denna medurs i fig. 23. P0 den andra anden av axeln 192 Or en arm 194 stelt fast, som rid den namnda vridningsrorelsen medbringar den under — — armen befintliga, vid skiftarmen 113 stelt fasta tappen 195. Harigenom bibringas denna skiftarm en motursvridning av sadan storlek, att spetsen 113a ay skiftarmen 113 kommer helt utanfor rotationsbanan for utspranget 115a och medbringaren 115. Vid nedtryckning av non-addtangenten payerkas icke skiftarmen 114 utan denna och skiftarmen 112 fOrbIiva i sina normallagen. Till foljd harav fOrblir hela skiftorgangruppen 111-114 och foljaktligen liven rakneverksaxeln 41 optiverkad yid maskingitngen for non-addition. RRneyerkshjulen komma darfOr att under hela maskingangen fOrbliya i ingrepp med kuggsektorerna 59. Det i tangentbordet inslagua beloppet kommer darfor att tryckas utan att rakneverkshjulen herOras daray. Rakneverkshjulen 40 payerkas ej av huggstangerna 34 under hela maskingangen. Nagon tiooverthring sker icke, enar ju rakneyerkshjulen 40 icke komma i ingrepp med kuggstangerna 34. When the non-addition key 15 is pressed, the amount (Wet) lake entered in the keyboard must be registered in the rake. The razor blades 40 remain dart & connected to the gear sectors 59, but these razor wheels should not be connected to the racks 34 during their upward and downward movement during the forward and reciprocating rotational movement of the main shaft 1. This is accomplished by riding the depression of the non-addtan. This means presses on an arm 191 (Figs. 23, 24), which is fixed to one end of the transverse shaft 192 in the mounting gables 139, 158. The shaft is rigidly connected with the key 193, which Mika rides on. towards the airmen 191 and thereby rotates it clockwise in Fig. 23. On the second end of the shaft 192 Or an arm 194 rigidly fixed, which rides the said rotational movement carries the existing - - arm existing, at the shift arm 113 rigidly fixed pin 195. Thereby is provided this shift arm is counter-rotated to such an extent that the tip 113a of the shift arm 113 comes completely outside the path of rotation of the projection 115a and the carrier 115. When the non-add key is depressed, the shift arm 114 is not paid without it and the shift arm 112 remains in its normal position. As a result, the entire shift member group 111-114 remains, and consequently the razor shaft 41 is activated by the machine gear for non-addition. The wheels will therefore remain in engagement with the gear sectors 59 throughout the machine entrance. The amount entered in the keyboard will therefore be pressed without the rake wheels being rotated. The razor wheel 40 is not paid for by the chopping rods 34 during the entire machine entrance. No thinning does not occur, since the rake irons 40 do not engage the racks 34.

Enar kopplingarna friii skiftmekanismen till rakneyerkshjulen 40 tdforligt beskriyits ovan, fir del nu endast att beskriva de avyikande anordningarna av skiltarmarna for astadkommande den ratliniga forskjutningsrorelsen L., genom medbringarens 1115 payerkan pa huvudskiftorganet 1111 och skift- eller manoverarmarna 1110, 1112, 1113 och 1114 yid de olika gangarterna. Pa sit satt som ovan utforligt beskrivits frankopplas rakneverkshjulen 40 fran tiooverforingskuggsektorerna 59 och kopplas till kuggstangerna 34 i installningsverket, nfir skiftorganaggregatet 1110-1114 forskjutes strackan L bakat (at hoger i fig. 26-37), och vice versa, Mir detta aggregat aterftires strackan L, frantat (------- at vanster i fig. 26-37). The modification shown in Figs. 26-37 is intended to provide a functionally more advantageous time schedule for the coupling and uncoupling of the rake wheels 40 to the racks 34 in the installation and the gear sectors 59 in the ten-transmission mechanism, respectively. In the embodiment according to Figs. 1 ---- 25, in total summing, the razor wheels 40 are brought into engagement with the aforementioned ten transmission gear sectors Si) during the last part of the advance of the shaft axis 10 (counterclockwise movement in Fig. 13), while in the embodiment according to Fig. 26 re-feeding occurs yid huyudaxelns return movement. One of the couplings of the shift mechanism of the rake gear wheels 40 has been briefly described above, in order now only to describe the deviating devices of the shield arms for effecting the linear displacement movement L. the different gaits. In the manner described in detail above, the razor wheels 40 are disconnected from the ten transmission gears sectors 59 and connected to the racks 34 in the installation, before the shifter assembly 1110-1114 is shifted the distance L backwards (to the right in Figs. 26-37), and vice versa. L, frantat (------- at vanster in fig. 26-37).

The pin 119 is coupled to the razor wheels 40 and their harrow members are described above (see under the heading shift mechanism above). This pin is fixed to the main shift member 1111 of the shift mechanism 111., 1113, 1114, 1114 and 1110. The shafts are rotatably mounted on the pin 1129 of the shift member 1111 and the shift arms are thus rotatable relative to each other, but still form a coherent unit which receives displacement movement of the carrier bearing 1115 fixed on the main shaft 10 of the machine. The shift members are connected to each other by means of tension springs in the following manner: A spring 1131 is a span between 1111 and 1113.

Armen 1110 drages av fjadern 300 alt med sitt ombockade utsprang 1110a anligga mot undersidan av armen 1113, och nar nu totalsummatangenten 14 svanger armen 1113 moturs i fig. 31, yrides foljaktligen Oxen armen 1110 moturs tills sistnamnda arm star an mot och hejdas av det utbockade utspranget 1111b pa. organet 1111. Omedelbart vid h&- j= av maskingangen slar nu det ombockade utspriinget 1115b an mot utspranget 1112a pa skiftarmen 1112, sä att skiftarmsaggrega- tet forskjutes strackan LA bakedhoger i fig. 31). Detta sker under vridningsvinkeln moturs hos huvudaxeln 10 under dennas framatslag. Under forsta delen av denim axels atergangsslag medurs aterfOras skiftarmarna any° strackan LA framat (at vanster i fig. 31 °eh 32) genom alt haken eller utspranget 1115c pa medbringaren 1115 slar an mot utspranget 1110b pfi. skiftarmen 1110, s0.som visas i fig. 32, och harigenom fOrskjuter skiftarmsaggregatet under vridningsvinkeln 4(1 hos huvudaxeln. 10. For this operation, the total sum key 14 is pressed and read on the above set in the depressed position, as shown in Fig. 31. The pin 161 on this key brings the shift arms 1113 and 1114 down by pressing the key. The spring 1133 which spans between the arms 1112 and 1114 is stronger (has a longer sea arm) than the spring 1132 which spans between the members 1111 and 1112, which is why the counter-rotation caused by the depression of the key, the arm 1114 the arm 1112 follows, in that the spring 1133 hails the arm 1112 for abutment against the Iran main shift member 1111 bent out protrusion 1111b. The arm 1110 is pulled by the spring 300 or with its bent-out projection 1110a abutting against the underside of the arm 1113, and now when the total sum key 14 swings the arm 1113 counterclockwise in Fig. 31, consequently the Taurus arm 1110 is rotated counterclockwise until the latter arm faces and is stopped by the bent-out sprung 1111b pa. the means 1111. Immediately at h & - j = of the machine entrance, the bent-out projection 1115b now strikes against the projection 1112a on the shift arm 1112, so that the shift arm assembly is displaced the distance LA bakedhoger in Fig. 31). This occurs at the angle of rotation counterclockwise of the main shaft 10 during its forward stroke. During the first part of the return stroke of the denim shaft clockwise, the shift arms are returned any distance LA (that left in Fig. 31 ° eh 32) through all the hook or projection 1115c on the carrier 1115 abuts against the projection 1110b pfi. the shift arm 1110, as shown in Fig. 32, thereby displacing the shift arm assembly below the angle of rotation 4 (1 of the main shaft. 10).

Transportsummatagning (subtotal). Transport sum taking (subtotal).

Nar man nedtrycker suhtotaltangenten 13, verkar dess tapp 180 (fig. 27 och 33) endast pa skiftarmen 1114, som alltsa svanges moturs i fig. 33. Pa det satt, som i foreghende stycke beskrivits for totalsummatagning medbringas harvid skiftarmen 1112, som svanges uppat (moturs) och alltsâ till anliggning mot det utbockade utspranget 1111h pa skiftorganet till (under inverkan av fjadern 1133). I borjan ay huvudaxelns framatslag moturs kommer under vinkeln pB utspranget 1115b pa medbringaren 1115 att genom anslag mot utspranget 1112a pa. skiftarmen 1112 fOrskjuta skiftarmsaggregatet strackan LA bakat, d. v. s. at hoger i fig. 33. Under sista delen av huvudaxelns 10 atergangsslag medurs (yinkeln i3B) aterfores skiftarmsaggregatet strackan LA framat (at vanster) genom att utspranget 1115b pa medbringaren 1115 slar an mot kanten 1111d pa organet 1111, pa liknande salt som ovan beskrivits under rubriken addition (fig. 30). When the suction total key 13 is depressed, its pin 180 (Figs. 27 and 33) acts only on the shift arm 1114, which is thus pivoted counterclockwise in Fig. 33. In the manner described in the preceding paragraph for total sum taking, the shift arm 1112 is pivoted upwards. (counterclockwise) and thus to abut against the bent-out projection 1111h on the shift member to (under the influence of the spring 1133). At the beginning of the forward axis of the main shaft counterclockwise, at the angle pB the projection 1115b on the carrier 1115 will abut against the projection 1112a pa. the shift arm 1112 Displaces the shift arm assembly straight LA backwards, i.e. to the right in Fig. 33. During the last part of the main shaft 10 return stroke clockwise (angle i3B) the shift arm assembly is stretched back LA forward (to left) by the projection 1115b on the carrier 1111 striking the edge 1111 the member 1111, on a similar salt as described above under the heading addition (Fig. 30).

Subtraktion. Subtraction.

Subtraktionstangenten 12 nedtryckes och verkar med sin tapp 182 (fig. 34, 35) pa skiftarmen 1114, som alltsa vrides moturs. I denna roreise medfoljer armen 1112 under inverkan av fjadern 1133, sa att dess anslag 1112a kommer in i rorelsebanan for utspranget 1115b p0. medbringaren 1115. Yid bOrjan ay huvudaxelns framatslag moturs forskjutes alltsa aggregatet 1110-1114 hakat (at hoger) frail det i fig. 31 till det i fig. 36 visade laget, alltsa strackan LA. Vid denna forskjutning slar armen 1113 an mot tappen 182 pa subtraktionstangenten och svanges harigenom moturs. Under forsta delen av huvudaxelns titergangsslag medurs (fig. 36) aterfores aggregatet 1110-1114 anyo strackan LA framat (at vanster i fig. 36) genom att utspranget 1115b p0. medbringaren 1115 slar an mot utspranget 1110b ph skiftarmen 1110 och salunda forskjuter skiftaggregatet under vinkein /313. The subtraction key 12 is depressed and acts with its pin 182 (Figs. 34, 35) on the shift arm 1114, which is thus turned counterclockwise. In this rudder travel, the arm 1112 follows under the influence of the spring 1133, so that its abutment 1112a enters the rudder path of the projection 1115b p0. the carrier 1115. Yid bOrjan ay the main axis' forward stroke counterclockwise, the assembly 1110-1114 is displaced hooked (at right) from the layer shown in Fig. 31 to the layer shown in Fig. 36, i.e. the distance LA. During this displacement, the arm 1113 strikes the pin 182 on the subtraction key and is thereby pivoted counterclockwise. During the first part of the titer stroke of the main shaft clockwise (Fig. 36), the assembly 1110-1114 is returned to the distance LA forward (at the left in Fig. 36) by the projection 1115b p0. the carrier 1115 strikes against the projection 1110b ph of the shift arm 1110 and thus displaces the shift assembly below the winch / 313.
