Description

Uppfinnare: F R Henriksson En utminuteringsapparat for vatskor liar foreslagits, vilken är forsedd med ett mane,- verorgan for en ventil for omvaxlande slutande och oppnande av ett tillopp till ett portioneringsrum och ett avlopp fran portioneringsrummet. Enligt den silunda foreslagna anordningen ar ventilen dessutom anordnad att omvaxlande sluta och oppna forbindelse mellan portioneringsrummet, it ena sidan, och dels en expansionsledning, dels alien ett inluftningsror, it andra sidan. Inventor: F R Henriksson A minimizing device for water chutes has been proposed, which is provided with a mane, - means for a valve for alternately closing and opening an inlet to a portioning room and a drain from the portioning room. According to the silunda proposed device, the valve is further arranged to alternately close and open a connection between the portioning space, on the one hand, and partly an expansion line, partly an aeration pipe, on the other hand.

Den. namnda expansionsledningen har forsta hand till andamal att m8jligg8ra avlopp for luft, som vid en tidigare -Vanning av portioneringsrummet introngt i detta. Man kan emellertid icke undvika, att med den uttrangande luften normalt aven folja vissa kvantiteter av den vdtska, som skall utminuteras, och for den skull liar man. anordnat expansionsroret tamligen langt, sit att ett hydrostatiskt tryck skall byggas upp i detta ror, vilket ar tillrdckligt for begransande av maximal mangd av den utminuterade vatskan, som kan tranga upp i expansionsroret. The. The said expansion line has the primary purpose of enabling drains for air, as in a previous irrigation of the portioning room intronged in this. It is inevitable, however, that with the expelling air normally also follow certain quantities of the liquid to be mined, and for that reason one liar. arranged the expansion pipe quite far, so that a hydrostatic pressure must be built up in this pipe, which is sufficient to limit the maximum amount of the mined liquid which can penetrate into the expansion pipe.

En sadan anordning är visserligen av mycket god funktionsduglighet, men i manga fall kan den av sarskilda orsaker stklla sig olamplig. Such a device is admittedly of very good functionality, but in many cases it can, for various reasons, prove unsuitable.

Sasom exempel kan namnas, att den ifragavarande anordningen kan vara avsedd fOr utminutering av varma drycker sasom kaffe och liknande, men det kaffe, som tranger upp expansionsroret kommer mellan en foregaende och en efterfoljande utminutering att kallna, varigenom det forlorar en avsevard del av sitt varde. As an example, the device in question may be intended for minimizing hot beverages such as coffee and the like, but the coffee which pushes up the expansion tube will cool between a previous and a subsequent minimization, whereby it loses a considerable part of its value. .

Som ett andra exempel kan namnas, att vid en utfOringsform av den. ifragavarande utminuteringsapparaten utminuteringen fullfolj es I tva etapper eller laser. Under den en.a bor portioneringsrummet fyllas, men for sakerhets skull aro anordningar vidtagna for att tvangsmassigt astadkomma ett visst tidsavbrott mellan denna fas och den andra fasen, under vilken portioneringsrummet aterigen tommes pa sitt innehall. Om nu tidsmellanrummet skulle bli alltfiir langt, sit Kan en tamligen avsevard kvantitet ay den utminuterade vatskan tranga upp i expansionsr8ret, och om detta icke ar tillrackligt voluminost, kan skvalning bliva foljden. As a second example, it may be mentioned that in an embodiment of it. In the case of the minuteing device, the minuteing is completed in two stages or laser. During one, the portioning space should be filled, but for the sake of safety, devices are taken to forcibly effect a certain time interruption between this phase and the second phase, during which the portioning space is again emptied of its contents. If the time interval were to become too long, a fairly considerable quantity of the depleted liquid could penetrate into the expansion tube, and if this is not sufficiently voluminous, swelling may follow.

A andra sidan kunna svarigheter foreligga att inom apparatens omkrets harbargera ett tillrackligt langt expansionsror, detta sit mycket mer som en nivaskillnad mellan vatskeniva i behallaren for den utminuterade vatskan och hogsta punkten pa expansionsroret maste finnas, motsvarande forefintligt tryck i den namnda behallaren. On the other hand, there may be similarities in harboring a sufficiently long expansion tube within the circumference of the apparatus, this is much more like a level difference between the water level in the container for the depleted liquid and the highest point on the expansion tube must be, corresponding to existing pressure in the said container.

Foreliggande uppfinning avser salunda en utminuteringsapparat for varma vatskor, vilken dr forsedd med ett manoverorgan for en ventil far omvaxlande slutande och Oppnande av ett tillopp till ett portioneringsrum och ett avlopp frail portioneringsrummet. En. avluftningsledning fir forbunden med ventilen pa sadant sail, att kommunikation bestar mellan avluftningsledningen och portioneringsrummet endast i huvudsak samtidigt med att kommunikation bestar mellan tilloppet och portioneringsrummet. The present invention thus relates to a minimizing apparatus for hot water shoes, which is provided with an actuator for a valve which alternately closes and opens an inlet to a portioning space and a drain from the portioning space. One. vent line for connected to the valve on such a sail, that communication exists between the vent line and the portioning space only substantially at the same time as communication exists between the inlet and the portioning space.

Enligt uppfinningen Or i avluftningsledningen i omedelbar narhet ay portioneringsrummet anordnad en flottorventil med en volym, som dr liten i forhallande till portioneringsrummets volym och med sadan verkan, att densamma genomslapper luft men tillslutes for all stromning, sedan vatska trangt upp I flottorventilens arbetsrum till en given hojd. According to the invention Or in the vent line in the immediate vicinity of the portioning chamber a float valve is arranged with a volume which is small in relation to the volume of the portioning chamber and with such an effect that it permeates air but is closed for all flow, then liquefied into the float valve working space to a given hojd.

Utelamnandet ay avluftningsroret innebar en avsevard forenkling ay apparaten, detta i forsta hand ay den. grund, att oppningen till avluftningsroret vanligen icke kunde appliceras vid portioneringsrummets hogsta punkt. The omission of the vent pipe meant a considerable simplification of the apparatus, this primarily of the device. due to the fact that the opening to the vent pipe could not normally be applied at the highest point of the portioning room.

Uppfinningen kommer nedan att narmare beskrivas i samband med bifogade ritning, pa vilken fig. 1 visar en langdgenomskarning av apparaten i dess helhet, under det att fig. 2 och 3 visa de olika lagen, som den. i appa- 2— — raten ingaende ventilen under bruk kan intaga. The invention will be described in more detail below in connection with the accompanying drawing, in which Fig. 1 shows a longitudinal section of the apparatus in its entirety, while Figs. 2 and 3 show the different layers as it. in the appliance 2— - the rate the valve during use can take.

Pa. fig. 1 antages apparaten vara myntautomatmanovrerad, men det ligger i uppfinningens natur, att den aven kan manOvreras pa annat salt. Den egentliga utminuteringsapparaten ar darvid betecknad med 10 och myntautomaten med 11. Myntautomaten kan vara av en var for andamalet lampad konstruktion, och den skall darfor endast beskrivas i korta drag. Den ar inrymd mom ett holje 12 och ar forsedd med en myntoppning 13. Omedelbart under myntoppningen 18 ar en vals 14 anordnad, sa att myntet, da det faller ned genom myntoppningen, upptages i en ficka valsen 14, dar det astadkommer koppling melIan valsens axel 15 och en utgaende axel 16 till utminuteringsapparatens portioneringsdelar. Axeln 15 stracker sig ut genom holjet 12 till en manOverratt 17; under det att axeln 16 medelst en medbringare 18 och en koppling 19 ar forenad med axeln 20 till portioneringsapparaten. Pa. Fig. 1, the apparatus is assumed to be coin-operated, but it is in the nature of the invention that it can also be operated on other salt. The actual minuteing machine is then denoted by 10 and the coin machine by 11. The coin machine can be of a construction which is otherwise lighted, and it must therefore only be described in brief. It is housed in a housing 12 and is provided with a coin opening 13. Immediately below the coin opening 18 is a roller 14 arranged so that the coin, as it falls down through the coin opening, is received in a pocket of the roller 14, where it provides coupling between the axis of the roller 15 and an output shaft 16 to the portioning portions of the minuteing apparatus. The shaft 15 extends through the housing 12 to a maneuvering wheel 17; while the shaft 16 is connected by means of a carrier 18 and a coupling 19 to the shaft 20 of the portioning apparatus.

Portioneringsapparaten innehaller i forsta hand ett portioneringsrum av avmatt rymd, utat begransat av en rorformig vagg 21 och tva gavlar 22 och 23. Gaveln 22 ar ansluten till inre kanten pa den rorformade vaggen 21 under inkoppling av en tatning 24 samt forsedd med ett centralt hal 25 med tatning 26 for axeln 20. Gaveln 23 är anordnad att fOrhinclas med portioneringsapparatens stativ 27, vilket exempelvis kan utgoras av -vaggen till en behallare for den dryck, som skall portioneras tit, exempelvis en kaffeberedare. Anslutningen sker medelst en del 28, som är framstalld i ett styeke med vaggen 23, och som innehaller vissa for anordningens funktion vitala delar. The portioning apparatus primarily comprises a portioning space of measured space, externally bounded by a tubular cradle 21 and two ends 22 and 23. The end plate 22 is connected to the inner edge of the tubular cradle 21 while connecting a seal 24 and provided with a central hall 25. with seal 26 for the shaft 20. The end 23 is arranged to be pre-hooked with the rack 27 of the portioning apparatus, which can for instance be constituted by the cradle of a container for the beverage to be portioned, for example a coffee maker. The connection is made by means of a part 28, which is made in a styeke with the cradle 23, and which contains certain parts vital to the function of the device.

Salunda loper centralt genom delen 28 en kanal 29 fOr tillforsel av den utminuterade vatskan. I omedelbar narhet av portioneringskarlets hagsta punkt befinner sig i vaggen en oppning, som kommunicerar med den enligt uppfinningen anordnade flottorventilen Over en kanal 30, vilken avslutas med en anslutningsbussning 31. I den undre halften av gaveln 23 ar ett avtappningshal forhundet med en avtappningsledning 33 for den portionerade vatskan. De tre oppningarna taekas av en vridbar ventilskiva 34, vilken medelst en bussning 35 Ur fast pa axeln 20, sa att den kommer att rotera vid vridning av handtaget 17. I skivan ar en radiellt riktad appning 36 upptagen av sadan bredd, att den i huvudsak ansluter sig till diametern pa oppningama till ledningarna 29 resp. 33. Salunda runs centrally through the part 28 a channel 29 for supply of the exhausted liquid. In the immediate vicinity of the highest point of the portioning vessel there is in the cradle an opening which communicates with the float valve arranged according to the invention. Over a channel 30, which ends with a connection bushing 31. In the lower half of the end 23 a drainage hall is obstructed by a drain line 33 for the portioned liquid. The three openings are taken by a rotatable valve disc 34, which by means of a bushing 35 is fixed on the shaft 20, so that it will rotate when the handle 17 is rotated. In the disc a radially directed opening 36 is occupied by such a width that it connects to the diameter of the openings to the wires 29 resp. 33.

I anslutningsbussningen 31 är en nippel 32 inskruvad, vilken uppbar den egentliga flottorventilen, vars hus 37 upptill Kr tackt av en overfallsforskruvning 41. I centrum av forskruvningen 41 ar ett avluftningshal 42 anordnat. I det mom holj et 37 fOrefintliga nottorkammarrummet är en flottor 43 anordnad. Screwed into the connection bushing 31 is a nipple 32, which carries the actual float valve, the housing 37 of which is at the top of Kr thanks to an overflow fitting 41. In the center of the fitting 41 a venting hall 42 is arranged. In the existing 37 room of the notary chamber, a fleet 43 is arranged.

Den uppbar pa sin oversida en ventilkropp eller liknande tatningsorgan 44 fOr samverkan med ett pd undersidan av forskruvningen 41 anordnat ventilsate 45, dd flottoren av intrangande valska lyftes upp till viss niva. Yentilkroppen 44 kan exempelvis best& av en metallring med en innanfOr anbragt packning. It carried on its upper side a valve body or similar sealing means 44 for co-operation with a valve set 45 arranged on the underside of the screw connection 41, when the float of penetrating roller is lifted up to a certain level. The yen body 44 may, for example, consist of a metal ring with a gasket arranged inside.

Anordningen fungerar pa foljande salt: Under senaste avtappning av dryck fran portioneringsanordningen har ventilskivan 34 overforts till det lage, som framgar av fig. 2. Ventilskivan 34 pressas normalt av en fjader till tatande anliggning mot gaveln 23. Med trycket frail fjadern samverkar aven vatsketrycket i det inre av portioneringsrummet. Dessa hada tryck aro tillrackliga for att astadkomma tatande anliggning mellan ventilskivan 34 och gaveln 23. Da ventilskivan Over-fares till det i fig. 2 visade laget kommer emellertid slitsen 36 att kommunicera med avtappningsledningen 33. Harvid upplitir det hydrostatiska trycket Iran portioneringsrummet mot ventilskivan 34, men daremot uppkommer ett try& frail ledningen 29 mot ventilskivan, vilket bestammes av den hydrostatiska hojden i kaffebryggningsapparaten eller den behallare, fran vilken vatska skall avtappas. Delta leder i sin fur till att ventilskivan 34 lyftes obetydligt fran gaveln 23, sa att en spalt Oppnas, genom vilken vatska kan lacka ut fran flottorrummet, kanalen och spalten till kanalen 33. For farhindrande av att vatska samtidigt lacker in i denna spalt fran kanalen 29 är kanalen 29 vid sin mynning forsedd med en elastisk tatning eller pack-fling, exempelvis av gummi. FOljden harav blir salunda, att samtidigt med att flott8rrummet tommes pa vatska flottoren sjunker till sitt understa lage. Ventilen 44 kommer salunda att oppnas for att slappa in den luft i portioneringsrummet, som har till andamal att genom spalten mellan gaveln 23 och ventilskivan 34 samt oversta delen av slitsen 36 komma in i portioneringsrummet och dar forhindra uppkomsten av undertryck eller vakuum under den portionerade vatskans utstromning. Portioneringsrummet har salunda tomts pa den portionerade vatskan, och i stallet har luft tillforts. The device operates on the following salt: During the last draining of beverage from the portioning device, the valve disc 34 has been transferred to the bearing shown in Fig. 2. The valve disc 34 is normally pressed by a spring to a tangential abutment against the end 23. The pressure of the spring also cooperates with the pressure in the spring. the interior of the portioning room. These had pressures are sufficient to provide a tactile abutment between the valve disc 34 and the end cap 23. When the valve disc is transferred to the layer shown in Fig. 2, however, the slot 36 will communicate with the drain line 33. In doing so, the hydrostatic pressure Iran occupies the portion space against the valve disc 34 , but on the other hand a try & frail line 29 arises against the valve disc, which is determined by the hydrostatic height in the coffee brewing apparatus or the container from which liquid is to be drained. Delta leads in its furrow to the valve disc 34 being lifted insignificantly from the end wall 23, so that a gap is opened, through which liquid can leach out from the float chamber, the channel and the gap to the channel 33. To prevent liquid from simultaneously leaching into this gap from the channel 29, the channel 29 is provided at its mouth with an elastic seal or packing flake, for example of rubber. The result is that at the same time as the float room is emptied of the liquid float, it sinks to its lowest level. The valve 44 will thus be opened to let in the air in the portioning space, which has the purpose of entering the portioning space through the gap between the end wall 23 and the valve disc 34 and the upper part of the slot 36 and thereby preventing the formation of negative pressure or vacuum under the portioned water tank. outflow. The portioning room has thus been emptied of the portioned liquid, and air has been supplied instead.

Insattandet air ett mynt i myntoppningen 13 medger nu, att ventilskivans axel vrides runt med hjalp av handtaget 17, varvid forst avtappningsoppningen 33 tamligen snabbt slates till. The insertion of a coin into the coin opening 13 now allows the shaft of the valve disc to be rotated by means of the handle 17, whereby first the draining opening 33 is closed rather quickly.

Efter fullbordandet av ett halvt varvs vridning kommer ventilskivan att sta. i det lage, i vilket den visas i fig. 3. Portioneringsrummet kommunicerar nu dels med roret 30 for anslutning till flottorkammaren, dels aven med roret 29 for tillforande as, ytterligare valska och for pafyllning av portioneringsrummet. Om eventuellt nagon del as, den vatska, som vid en. tidigare pafyllning tillforts portioneringsrummet, alltj amt skulle kvarsta —3 flottorkammaren eller i ledningarna till denna, sa kommer denna vatskekvantitet nu snabbt alt aterforas till portioneringsrummet. Samtidigt fylles detta genom vatska, som till-cores genom roret 29. Alit efter som portioneringsrummet ph detta salt fylles med vatska, undantringes den i rummet tidigare befintliga luften genom roret 30; anslutningsmuffen 31, flottOrkammaren innanfor holjet 37, ventilen 44-45 och avluftningsoppningen 42. Det är under sista fasen av phfyllningsperioden, som en mindre kvantitet av vatskan tranger upp genom roret 30 och anslutningsmuffen 31 till flottorkammaren. Denna vatska kommer, sedan den natt tillracklig hojd i flottorkammaren, att astadkomma flottorens 43 lyftning, varvid ventilkroppen 44 kommer till tatande anliggning mot ventilsatet 45, och kers-Edende utrymme i flottorkammaren bildar en luftkudde, vars successiyt stegrade tryck forhindrar, att ytterligare vdtska tranger upp i flot- torkammaren. I varje fall har yid detta tillfalle med betryggande sakerhet portionerings- rummet blivit fyllt med den vatska, som skall portioneras ut. After the completion of a half turn rotation, the valve disc will stand. in the layer in which it is shown in Fig. 3. The portioning space now communicates partly with the rudder 30 for connection to the float chamber, partly also with the rudder 29 for supplying ash, further rolling and for filling the portioning space. If possibly any part as, the vatska, as at a. previously filling has been added to the portioning room, everything would remain —3 the float chamber or in the pipes to it, so this quantity of water will now be quickly returned to the portioning room. At the same time this is filled by liquid, which is added through the tube 29. After the portioning space ph this salt is filled with liquid, the air previously present in the room is excreted through the tube 30; the connecting sleeve 31, the float chamber inside the housing 37, the valve 44-45 and the vent opening 42. It is during the last phase of the filling period that a small quantity of the liquid pushes up through the tube 30 and the connecting sleeve 31 to the float chamber. This liquid will, since that night sufficient height in the float chamber, bring about the lifting of the float 43, the valve body 44 coming into abutting abutment against the valve seat 45, and curved space in the float chamber forming an air cushion, the successively increased pressure of which prevents further liquid pressure. up in the float chamber. In any case, yid this case with reassuring certainty the portioning room has been filled with the liquid to be portioned out.

Sedan portioneringsrummet pa detta satt blivit fyllt, fortsfittes vridningen av ventilskivan ytterligare ett halvt vary till det lage, som visas i fig. 2, varvid kommunikation oppnas mellan portioneringsrummet och utloppsledningen 33, och den utminuterade vatskan bSrjar rinna ut genom denna ledning. Ledningen 33 Mr darvid vara av sadan vidd, att nagon ytspanningsbarriar lake uppkommer i ledningen. Skulle namligen inluftningen genom spalten mellan gaveln 23 och ventilskivan 31 vara otillracklig, sâ kommer luft Oven att tillairas till portineringsrummet i motstrOmning mot den utrinnande vatskan, tills all vatska runnit ut, och portioneringsrummet blivit taint. Darefter har utminuteringen fullbordats, oth hela apparaten har atervant i det vilolage, som den intog narmast fore de ovan skildrade funktionerna togo sin borjan. Det Or synbarligen av betydelse att erforderlig tid star till buds for vatskans instromning i portioneringsrununet, vilket agar rum i huvudsak under den tid, i vilken ventilskivan star i sitt i fig. 3 visade lage, dvs. efter ett halvt varvs vridning fran det i fig. 2 visade vilolaget. For att sakerstalla att ventilskivan icke vrides forbi detta lage alltfor snabbt, kan man anordna apparaten sa., aft den tvangsmassigt bringas att stanna viss tid I det angivna laget. Ett sarskilt enkelt sat att astadkomma derma verkan är alt inratta myntautomaten sa, att ilaggandet av tvh mynt Or erforderligt for vridning av ventilskivan ett halt vary, namligen ett forsta mynt for vridning av ventilskivan det forsta halva varvet och ett andra mynt for vridning av ventilskivan det andra halva varvet. Vid en sadan anordning bar myntOppningen pa sedvanligt salt vara hegransad sa, ail den endast kan mot- taga all mynt, men det kan vara bekvamt att anordna den sO, att det andra av de tva myn- ten kan instickas i myntoppningen och kvarhallas dar utan att falla ned, tills det forsia. myntet lamnat myntspringan och faller ned' i den under myntautomaten befintliga behal-- laren, samt darefter valsen vrides tillbaka till utgangslaget for att frail myntoppningen mottaga det andra myntet. liven andra anord-• ningar kunna forekomma for samma anda, mai. After the portioning space has been filled in this way, the rotation of the valve disc continues for another half to the layer shown in Fig. 2, communication being opened between the portioning space and the outlet line 33, and the exhausted liquid begins to flow out through this line. The line 33 Mr thereby be of such a width that any surface tension barrier lake arises in the line. Namely, should the ventilation through the gap between the end wall 23 and the valve disc 31 be insufficient, then air will be supplied to the porting room in countercurrent to the flowing liquid, until all liquid has run out, and the portioning room has become tainted. After that, the minimization has been completed, and the whole apparatus has returned to the state of rest, which it took almost immediately before the functions described above took their beginning. It is apparently important that the necessary time is available for the inflow of the liquid into the portioning rune, which takes place mainly during the time in which the valve disc is in its position shown in Fig. 3, i.e. after half a turn rotation from the resting layer shown in Fig. 2. In order to ensure that the valve disc does not rotate past this layer too quickly, the apparatus can be arranged so that it is forcibly brought to a certain time in the specified position. A particularly simple way of achieving this effect is to set up the coin dispenser so that the insertion of two coins is required for rotating the valve disc a variable amount, namely a first coin for rotating the valve disc the first half turn and a second coin for rotating the valve disc there. second half lap. In such an arrangement the coin opening on ordinary salt should be screened so that it can only receive all coins, but it may be convenient to arrange it so that the other of the two coins can be inserted into the coin opening and retained there without to fall down, until it forsia. the coin leaves the coin slot and falls into the container under the coin machine, and then the roller is turned back to the starting layer to receive the second coin from the coin topping. life other devices • may occur for the same spirit, mai.

Portioneringsanordningen kan givetvis anvandas i annat sammanhang an med en myntautomat. liven i detta fall Or det emellertid av betydelse, att ett uppehall i kringvridningen av ventilskivan sker, da portioneringsrummet skall fyllas, sa att erforderlig tid erhalles for fyllandet. I detta fall kan man exam-pelvis anordna handtaget sh, att det endast kan vridas ett halvt vary i taget. Kopplingen 19 Mr dd. Tara sd. utford, att den under vridningen ay handtaget medtager axeln 20 i sin rorelse, men under atergangen av handtaget skall genom en sn.apphakekonstruktion eller liknande axeln 20 kvarhallas i det intagna laget. DO darefter handtaget for andra gangen vrides ett halvt vary, medtages aterigen genom snapphakens funktion axeln 20, sa. att ventilskivan kommer att vridas aterstoden for fullbordande av ett halt -yam rotation, dvs. ventilskivan overfores under det forsta halva varvet fran laget enligt fig. 2 till laget enligt fig. 3 och under det andra halva varvet Aterigen fran laget enligt fig. 3 tillbaka till laget enligt fig. 2. The portioning device can of course be used in another context than with a vending machine. life in this case However, it is important that a pause in the rotation of the valve disc takes place when the portioning space is to be filled, so that the required time is obtained for filling. In this case, the handle sh can be arranged, for example, so that it can only be turned half a turn at a time. The coupling 19 Mr dd. Tara sd. challenge that during rotation of the handle it carries the shaft 20 in its movement, but during the return of the handle it must be retained in the intake layer by means of a snap-hook construction or similar shaft 20. DO then the handle for the second time is turned half vary, is again included by the function of the snap hook shaft 20, sa. that the valve disc will rotate the remainder to complete a halt -yam rotation, i.e. the valve disc is transferred during the first half turn from the layer according to Fig. 2 to the layer according to Fig. 3 and during the second half turn Again from the layer according to Fig. 3 back to the layer according to Fig. 2.

Apparaten kan for kontroll ay antalet utminuterade enhetsvolymer forses med ett rakneverk. For andamalet Or pa axeln frhn kopplingen 19 ett kugghjul 39 pasatt, vilket befinner sig I ingrepp rued ett kugghjul 40, vilket med ph ritningen icke visade medal Over-for sin rorelse till rakneverket. The device can be equipped with a rake for control of the number of mined unit volumes. For the second part Or on the shaft from the clutch 19 a gear 39 is fitted, which is in engagement with a gear 40, which with the ph drawing did not show medal Over-for its movement to the rake.

Uppfinningen Or givetvis icke inskrankt till den sarskilda utforingsform, som ovan beskrivits och shsom utforingsexempel pa uppfinningen askadliggjorts pa ritningen, utan olika modifikationer kunna fOrekomma inom uppfinningens ram. The invention is of course not limited to the particular embodiment, as described above and as an embodiment of the invention has been rendered harmless in the drawing, but various modifications may occur within the scope of the invention.
