CLASS B 65 f PATENTARY TIME FROM 24 OCTOBER 1956 PROVIDED ON 4 MAY 1961 PUBLISHED 4 JULY 1961 Ans. 9625/1956 on 24/10 1956Miran a drawing A STIHL, NEUSTADT B. WAIBLINGEN, THE FEDERAL REPUBLIC OF GERMANY For barbaric, motorized chain saws intended stone sawing chain Priority begtird frail October 24 and December 31, 1955 and June 21, 1956 part edge, to use saw chains provided with grinding elements, 'which are inlaid in V-shaped grooves in lankaina and convexly crooked Orval in lank-arms langdriktning .som tvaniktning. Stone saw chains of the delta type, however, are not usable for insert sawing, since the side surfaces of the laths would then soon be worn down by the stone.

Uppfinningen liar till andamal att Ostadkomma en for barbara, motordrivna kedjes& gar anvandbar stensagkedja, som -ar lamplig for sa-val skarning som instickningssagning i hard sten. En 'sadan kedja Or lagd over en styrskena och .minst .ett kedjehjul och Or sammans:att .av lankar, vilka omvaidande uppbara slipelement .och 'dessas ingreppsdjup begransande element, varvid slipelementens arbetsytor bestâ av hard karbid, diamantsplitter eller hardmetall. Del for denna kedja kammtecknande Or, att ,slipelementen :aro pasatta pa 'sina respektive kedjelankar och att deras arbetsytor utskjuta utanfor lankarnas mot kedjehjuleris axlar vinkelrata sidoytor samt ph i och for .sig kant silt Oro konvext avrundade i saval lankarnas langdriktning som tvarriktning. Lampligen kunna A.tminstone en del av de ,djupbegransande -elementen pa 'samma sat som 'slipelementens arbetsytor vara konvext avrundade ,saval i lankarnas langdriktning som tvarriktning. The invention has for its object to provide a stone-saw chain which can be used for barbaric, motor-driven chains, which is suitable for both cutting and plug-in sawing in hard stone. Such a chain Or laid over a guide rail and at least one sprocket and Or together: that of slats, which extensively support abrasive elements. Part for this chain comb-drawing Or, that, the grinding elements: are fitted on their respective chain anchors and that their working surfaces protrude beyond the shafts of the shafts towards the shafts of the sprocket at angular side surfaces as well as ph in and .sig edge silt. At least some of the deep-limiting elements can be convexly rounded in the same way as the working surfaces of the grinding elements, both in the longitudinal direction of the laths and in the transverse direction.

Slipelementen ha sadan form, att de vid skiirning av- en plan skara komma till anliggming utefter en star del av sin langd, medan de vid en krokt skara ej endast haka i med ena kanten utan Oven dar tangera den krokta skaran langs ett visst avsnitt. Sagkedj an konstrueras fullstandigt symmetriskt, sa att den lid efter an:nan kan upplaggas p0 styrskenan i omvand riktning. Harigenom erhalles den fordelen, att de efter en viss tid snedslitna slipytorna ater automatiskt skarpas. The grinding elements are shaped in such a way that when cutting a flat group they come into contact along a rigid part of their length, while in a crooked group they not only hook in with one edge but above touch the crooked group along a certain section. The saw chain is constructed completely symmetrically, so that it can be supported one after the other on the guide rail in the opposite direction. This gives the advantage that after a certain time the sloping grinding surfaces are automatically sharpened again.

Enligt uppfinningen anordnas vidare sa, alt utryrnme for avsattning av stenmj51 erMlles ej endast mellan kedjelankarna utan Oven i sjalva slipytorna. Stenmjolet kvarstannar emellertid ej i dessa utrymmen utan bortslungas pa grund av kedjans stora lophastighet samt p5. grund av centrifugalkraften vid kedjans gang runt det med relativt ii-ten diameter fiirsedcla kedjedrivhjulet. Genom kedjelankarnas rorlighet I fOrhMlande till varandra uppnas, att vid vane vary f Or kedjan alltid nya slipkorn komma till ingrepp ph sail-ma stalle i skaran. Skarans riktning blir darfor aldrig exakt likformig, i det att slipkedj an. verkar som en fil, yid vilken man efter varje slag avsiktligt andrar filningsriktningen nagot for att uppna battre ingrepp. Just genom derma Ella forskjutning av de olika kedjeankarna i forhallande till varandra skar sagkedjan skaran nagot bredare On sin egen bredd och fOrhindrar darigenom fastklamning. According to the invention, it is further provided that all the space for depositing stone flour is formed not only between the chain anchors but also in the grinding surfaces themselves. However, the stone flour does not remain in these spaces but is thrown away due to the chain's large running speed and p5. due to the centrifugal force at the passage of the chain around the relatively small diameter of the sprocket. Through the mobility of the chain anchors in relation to each other, it is achieved that, as usual, new abrasive grains always come into engagement with the chain in the crowd. The direction of the joint therefore never becomes exactly uniform, in that the grinding chain. acts as a file, yid which after each stroke is deliberately changed the filing direction slightly to achieve better engagement. Precisely through this Ella displacement of the various chain anchors in relation to each other, the saw chain cuts the crowd somewhat wider on its own width and thereby prevents clamping.

Enligt en utforingsform av -uppfinningen besta. slipelementen av parlformade slipkroppar, vilka Oro roterbart monterade ph. som ha-rare tjanande kedjelankar. Vid kedjans drift komma alltsa dessa slipkroppar att hela ti-den vrida sig langsamt, sh. att stancligt nya slipkorn komma till inverkan, varvid slipkroppens hela yta avnotes likformigt. Vidare uppnas, att slipkropparna med sina runda ytor anligga i skaran i stenen utan att intranga i sprickor eller hal. De parlformade slipkropparnas montering och demontering Or mycket enkel, cla man for detta andamal endast behover insatta eller urta.ga bultar. According to one embodiment of the invention. the grinding elements of pearl-shaped grinding bodies, which Oro rotatably mounted ph. as ha-rare serving chain links. During the operation of the chain, all of these abrasive bodies will constantly rotate slowly, sh. that constantly new abrasive grains come into effect, whereby the entire surface of the abrasive body is delineated uniformly. Furthermore, it is achieved that the abrasive bodies with their round surfaces abut in the groove in the stone without penetrating into cracks or slippery. Assembly and disassembly of the pearl-shaped abrasive bodies Or very simple, cla for this purpose only need to insert or remove bolts.

Enligt uppfinningen kunna de parlformade kropparna uppbyggas av en jarnkarna med 2— — en bela.ggning av mjukare bararmassa, I vii-ken. ett mycket finkornigt hart material ar inbaddat. Soni barannassa kan lampligen hardmetall anvandas, men man kan aven anvanda en annan, mjukare metall eller ett an-flat material, exempelvis plast, eftersom det egentliga slipningsarbetet ej utfOres av bararmassan utan av de i denna inbaddade kornen. Slipkornen besta av hard karbid, diarnantsplitter eller hardmetall. Sarskilt lamplig är diamant pa. grund av dess hoga hardhet. En slipkropp med en belaggning av en massa innehallande fina diamantkorn har salunda en betydantle hallbarhet, och sagkedjan kan da tillatas att arbeta med mycket hog rotationshastighet, exempelvis 20-40 m/sek. According to the invention, the bead-shaped bodies can be built up of an iron core with a coating of softer bar mass, in the vii-ken. a very fine-grained hard material is embedded. Soni barannassa can be suitably cemented carbide, but you can also use another, softer metal or a flat material, for example plastic, since the actual grinding work is not performed by the bar mass but by the grains embedded in it. The abrasive grains consist of hard carbide, diarnate splinters or carbide. Particularly suitable is diamond pa. due to its high hardness. An abrasive body with a coating of a mass containing fine diamond grains thus has a considerable durability, and the saw chain can then be allowed to work at a very high rotational speed, for example 20-40 m / sec.

Genom alla dessa atgarder blir den bar-barn, motordrivna kedjesagen ett verktyg, med vilket man kan saga aven den hardaste sten, och detta galler ej endast natursten utan aven konststen, betong och jarnbetong. Exempelvis kan kedjesagen med fordel snabbt insattas i katastroffall och vid pionjarsarbete. Through all these actions, the bare-child, motor-driven chainsaw becomes a tool with which one can saw even the hardest stone, and this applies not only to natural stone but also to artificial stone, concrete and reinforced concrete. For example, the chain saw can advantageously be used quickly in the event of a disaster and pioneering work.

Vid upprymningstanden enligt fig. 1 bestar sjalva lanken 1 av plat saint är pa kant satt forsedd med hal 3 for nitar och en medbringarnock 2 vid undre kanten. Vid den ovre kanten är platen forsedd med flikar 4, som aro vikta omkring- en bult 5, pa vilken en parl formad slipkropp 6 Or vridbart monterad. Den parlformade slipkroppen är sakrad mot farskjutning i langdriktningen med hjalp av brick.or eller ringar 7. Den parlformade slipkroppen 6 bestar enligt detta exempel pa kant satt av t. ex. mjukt gotstal, och pa. dess klotformade yta aro hardmetallkorn p0. kant salt fasta genom svetsning, pressning e. d. Sasom framgar av fig. 3, bestar bulten S av ett skaft 8 med ett huvud 9 vid ena anden. Vid den andra Auden finnes en rilla 10 for mottagande av en lasring. Bulten kan emellertid Oven. yarn utformad pa annat satt, exempelvis som en glatt nitbult, vars bada andar efter monteringen uppstukas till hu-vuden. Bulten 5 befinner sig vagratt, dvs. paralIellt med skarningsriktningen, sasom framgar av fig. 1, da. styrskenan uppbar en hrytrulle for instickningssagning. Sa lange den parlformade slipkroppen 6 laper Over styrskenan, kommer den knappast aft vrida sig, eftersom den glidande och ratlinigt ingriper mot stenen. DA den daremot kommer upp pa. brytrullen, vrider den sig nagot, eftersom stentrycket har verkar snett mot bultens axel, och slipkroppen alltsa ingriper mot stenen ej endast upptill utan Oxen med sin ena 'sida. Om instickningssagning ej ager rum, halles bulten lutande en vinkel a mot horisontalplanet. Slipkroppen kommer da att vrida sig nagot Oven vid glidningen Over styrskenan, om den ingriper mot skaran i stenen endast pa ena sidan, dvs. om den har en liten excentricitet e, sasom visas i fig. 5. Denna excentricitet Ar Oven onskvard far att skaran skall bliva bredare an slipkroppens diameter, dvs. for att mojliggora friskarning. Lanken 11 i fig. 4 och 5 ãr ej farsedd med nagon medbringarnock 2. At the reaming stand according to Fig. 1, the tongue itself 1 consists of a flat saint and is fitted on the edge with a hall 3 for rivets and a carrier cam 2 at the lower edge. At the upper edge the plate is provided with tabs 4, which are folded around a bolt 5, on which a bead-shaped abrasive body 6 is rotatably mounted. The pearl-shaped abrasive body is secured against longitudinal shear with the aid of washers or rings 7. According to this example, the pearl-shaped abrasive body 6 consists of edges set by e.g. soft gotstal, and pa. its spherical surface aro carbide grains p0. edge salt fixed by welding, pressing, etc. As can be seen from Fig. 3, the bolt S consists of a shaft 8 with a head 9 at one end. At the second Auden there is a groove 10 for receiving a laser ring. However, the bolt can Oven. the iron is designed in another way, for example as a smooth rivet bolt, whose two spirits are mounted to the heads after assembly. The bolt 5 is located horizontally, ie. parallel to the cutting direction, as shown in Fig. 1, da. the guide rail carried a shroud roll for insert sawing. As long as the pearl-shaped abrasive body 6 laps over the guide rail, it will hardly turn, as it slides and steers linearly against the stone. DA it, on the other hand, comes up on. the breaking roller, it turns slightly, because the stone pressure has acts obliquely against the shaft of the bolt, and the grinding body thus engages against the stone not only at the top but the Taurus with one 'side. If plug-in sawing does not take place, the bolt is inclined at an angle a to the horizontal plane. The abrasive body will then turn slightly. if it has a small eccentricity e, as shown in Fig. 5. This eccentricity. to enable recovery. The link 11 in Figs. 4 and 5 is not fitted with a carrier cam 2.

Kedjelankarna monteras som en vanlig trippellankkedj a for trasagar. I ett spar i styrskenan 12 glider upprymningselementets 13 nock, medan kedjelankarna 14 och 15 styras pa skenan, och alla tre Oro sammanhallna av nitar 16. The chain anchors are mounted as a standard triple chain for trasagar. In a groove in the guide rail 12, the ridge of the reaming element 13 slides, while the chain anchors 14 and 15 are guided on the rail, and all three Oro are held together by rivets 16.

For att Oka antalet slipkroppar per kedja kan varje kedjelank vara forsedd med tva parlformade slipkroppar, sasom framgar av fig. 7. Kedjelanken Or da Oven forsedd med en mittre omvikningsflik 17. Om flera, t. ex. fyra, parlformade slipkroppar skola anbringas pa. en kedjelank, är det nodvandigt att Oka delningen, sfisom visas i fig. 8. For att alla fyra slipkropparna skola komma till ingrepp, da de befinna sig Over brytrullen, maste i detta fall de bada mellersta slipkropparna 18 oeh 19 ha stOrre diametrar an de bada yttre 20 och 21. Detta Or emellertid ogynnsamt i de fiesta fall, och sasom visas i fig. 9 anvander man for detta andamal hellre en pa. lanken 22 monterad, krokt eller av flera delar bestaende bult 23. Vid instickningen tagas harvid alla fyra slipkropparna samtidigt i ansprak, me-dart endast de bada mellersta komma till inverkan vid glidningen Over styrskenan. In order to increase the number of abrasive bodies per chain, each chain link can be provided with two bead-shaped abrasive bodies, as shown in Fig. 7. The chain link Or da Oven is provided with a central folding flap 17. If several, e.g. four, pearl-shaped abrasive bodies must be applied. a chain link, it is necessary to increase the pitch, as shown in Fig. 8. In order for all four abrasive bodies to engage, as they are above the breaking roller, in this case the two middle abrasive bodies 18 and 19 must have larger diameters than the both outer 20 and 21. However, this is unfavorable in most cases, and as shown in Fig. 9, a pa is preferably used for this purpose. The tongue 22 is mounted, hooked or bolted in several parts.

— — For att undvika en far kraftig in.pressning stenskaran kan man enligt fig. 10 och 11 mellan tva arbetande kedjelankar infoga en lank, som begransar ingreppsdjupet. Derma djupbegransande lank 24 Sr upptill forsedd med en takformigt krokt yta 25, som exempelvis är 0,2 mm lagre an slipkropparna. Darigenom forhindras„ att slipkropparna for varje gang intranga djupare an 0,2 mm i stenen, varigenom overbelastning undvikes. According to Figs. 10 and 11, in order to avoid a heavy pressing of the stone cut, a tongue can be inserted between two working chain anchors, which limits the depth of engagement. This depth-limiting tongue 24 Sr is provided at the top with a roof-shaped curved surface 25, which is, for example, 0.2 mm lower than the abrasive bodies. This prevents the abrasive bodies from penetrating deeper than 0.2 mm into the stone each time, thus avoiding overload.

Shgkedjan enligt uppfinningen kan exempelvis vara anordnad sá, som visas i fig. 12. Sedd fran vanster i fig. 12 best Sr sh.gkedjan av en lank 26 med en slipkropp, 'som Sr placerad till hoger om sagkedjans vinkelratt mot kedjehjulens axlar giende mittplan, en lank 27 med ett djupbegransande element, en lank 28 med en slipkropp placerad till vanster om namnda mittplan, en lank 27 med djupbegransande element, en Iank 26 med 'slipicropp belagen i namnda plan, och slutligen en lank 27 med djupbegransande element, varph samma ordningsfoljd upprepas. Det bar observeras, aft de lankar, som uppbara excentriskt anbragta slipkroppar, aro insatta parallella med blindlankar 29. The chain according to the invention may, for example, be arranged as shown in Fig. 12. Seen from the left in Fig. 12, the chain of the shaft 26 consists of a tongue 26 with a grinding body, which is located to the right of the saw chain's perpendicular to the sprockets' axes. , a lank 27 with a deep-limiting element, a lank 28 with a grinding body placed to the left of said center plane, a lank 27 with deep-limiting elements, a Iank 26 with a grinding body coated in said plane, and finally a lank 27 with deep-limiting elements, warp the same sequence is repeated. It should be noted that the strands, which support eccentrically arranged abrasive bodies, are inserted parallel to blind strands 29.

En annan konstruktion visas i fig. 13. Sedd frau vanster i figuren Sr sagkedj an har gammansatt av en lank 30 med tva parlformade slipkroppar, som aro placerade excentriskt pa ena sidan om sagkedjans vinkelratt mot kedjehjulens axlar gh.ende mittplan, en s. k. upprymningstand 31 med parlformad slipkropp belagen i namnda plan, en lank 33 med tva parlformade slipkroppar anordnade excentriskt ph andra sidan cm namnda mittplan samt en upprymningstand 31 med parlformad slipkropp belagen i mittplanet, varph. ordningsfoljden upprepas. De lankar, som uppbara slipkropparna, aro Sven har hopparade med blindlankar 32. Another construction is shown in Fig. 13. Seen from the left in the figure. with a pearl-shaped abrasive body coated in said plane, a lane 33 with two pearl-shaped abrasive bodies arranged eccentrically on the other side cm of said central plane and a reaming tooth 31 with a pearl-shaped abrasive body coated in the middle plane, warp. the order is repeated. The longs that support the abrasive bodies, aro Sven has jumped with blind longs 32.

I stallet for de djupbegransande elementen 27 kan man aven anvanda lankar med avnatta parlformade slipkroppar eller lankar med parlformade kroppar utan hardmetallbelaggning. Manga andra kombinationer kunna Sven astadkommas med hj alp av de beskrivna kedjelankarna. Givetvis kunna kedjor med dylika kedjelankar anvandas far skarning i hada riktningarna. For hopnitningen kan man anvanda saval solida nitar som haLnitar. De vanliga styrskenorna behova ej andras varken nar det gdller dubbellankskedjor eller trippellankskedjor, och ej heller behova nagra and-ringer vidtagas betraffande den motordrivna kedjesacfbens kedjedrivhjul eller &riga delar. I stalletfor trippellankskedjor kunna ph liknan.de satt aven dubbellankskedjor forses med dylika parlformade 'slipkroppar. Instead of the depth-limiting elements 27, it is also possible to use tongues with abrasive pearl-shaped abrasive bodies or tongues with pearl-shaped bodies without cemented carbide coating. Many other combinations can be achieved by Sven with the help of the described chain links. Of course, chains with such chain links can be used for cutting in different directions. For riveting, you can use both solid rivets and half rivets. The usual guide rails do not need to be used by others, neither in the case of double-link chains nor triple-link chains, nor do any need for any changes to be made to the sprocket or other parts of the motor-driven chain saw. Instead of triple link chains, ph liknan.de can also be set with double link chains provided with such pearl-shaped 'grinding bodies.

I fig. 14 visas som utforingsexempel en kedj a med lankar barande slipelement. Slipytorna bildas darvid av en. fast, med diamant- eller karbidkorn genomgaende blandad slipmassa, som Sr formad sa, att den utan skarpa kanter med stor yta effektivt anligger mot skarslarans botten. Styrskenan 43, som har for en- kelhetens skull Sr -visad som ett bagformigt: element utan brytrulle, Sr tangs omkretsen ut-- bildad med ett rannformigt spar 45 ph samma satt som vanligen Sr fillet vid trippellankkedjor. I motsats till de Janda styrskenorna ar den forsedd med kanaler 44 far tillforsel av spolvatten eller kylvatten. Sj diva kedjan be-star i sitt enklaste utforande av endast tva slags lankar, namligen slipelement barande lankar 35 och dessa farenande lankar 48. Lankarna sammanhallas av i och for sig kanda, mycket latt utbytbara halnitar 34. Lankarnas utforande ar det i saraband med halnitar vanliga, dvs. de aro utbildade med inat vanda koppformiga urtagningar for upptagande av dragkraften. Varje 'slipelement Sr nedtill for-sett med medbringarnock 46 (fig. 1'5-18) och Over denna ett liv 11 med Mit Utbytbara ringer 42 'samt overst en flansdel 36. En. med dia.- rnantkorn blandad mas'sa 37, som p5 vanligt satt kan hesta av hardmetall, stSl, brons, Oast eller nagon specialmetall, Sr genom svetsning, 18dning eller pa annat slit fast vid derma flans 36. Fig. 14 shows as an exemplary embodiment a chain with string-bearing grinding elements. The grinding surfaces are then formed by one. solid, mixed with diamond or carbide grains through mixed abrasive mass, as Sr shaped said, that it without sharp edges with a large surface effectively abuts against the bottom of the skarslar. The guide rail 43, which for the sake of simplicity has Sr -shown as a bag-shaped: element without a break roller, Sr tang circumference formed-- formed with a rim-shaped groove 45 ph the same set as usual Sr fillet at triple link chains. In contrast to the Janda guide rails, it is equipped with channels 44 for the supply of flushing water or cooling water. The seven-chain consists in its simplest design of only two types of links, namely grinding element-bearing links 35 and these traveling links 48. The links are held together by kanda, very easily interchangeable tail rivets 34. The design of the links is in saraband with tail rivets common, ie. they are trained with inat vanda cup-shaped recesses for absorbing the traction force. Each 'grinding element Sr is provided at the bottom with a carrier cam 46 (fig. 1'5-18) and above this a life 11 with Mit Interchangeable rings 42' and at the top a flange part 36. A. with dia.- rnant grain mixed mass'a 37, which in the usual way can be made of cemented carbide, steel, bronze, Oast or any special metal, Sr by welding, 18dning or on other wear attached to this flange 36.

Om sliptanden 35 gives det i fig. 15 visade tvarsnittet, skar den sig sjalv fri p5 grund av slipvinkeln a', -silken dock kan vara tamligen liten. If the grinding tooth 35 is given the cross-section shown in Fig. 15, it cuts itself free due to the grinding angle α ', however, the silk may be rather small.

Vid utforandet enligt fig. 16 utskjuter den med diamant belagda slipmassan 37 pa hada sidor om flansen 36, varigenom en annu battre friskarning erhalles. In the embodiment according to Fig. 16, the diamond-coated abrasive mass 37 projects on either side of the flange 36, whereby an even better fresh cut is obtained.

Sasom visas i fig. 14, kunna slipta.nderna 35 framstallas med genomghen:de 'slipytor. Vid starre kedjor avbrytas dock slipytorna genom spalter 40, som aro avsedda att tillfalligt mottaga det avrivna stenmjalet. Sliptanden enligt fig. 17 lampar sig i synnerhet for instickningsskarning med stor radie pa brytrullen eller det bagformiga elementet och anligger dli samtidigt med hela sin overyta mot skarans -batten. Om man samtidigt skill utfora saval raka skaror som instickningsskarning, anvandes t. ex. sliptanden enligt fig. 18. I skarans raka del, alltsa vid .styrskerrans framsida, komma slipytorna 39 da att helt anligga mot skaran. Over brytrullen 'eller det bagformiga elementet komma emellertid dessutom Sven de ph bada sidor om slipytorna 39 anbragta avrundade ytorna 38 till anliggning mot stenen. Under ett vary for kedjan bliva pa sa salt samtliga slipytor satta i arbete. As shown in Fig. 14, the grinding surfaces 35 can be made with the through grinding surfaces. In the case of rigid chains, however, the grinding surfaces are interrupted by slots 40, which are intended to receive the torn stone flour by chance. The grinding tooth according to Fig. 17 is particularly suitable for insertion cutting with a large radius on the breaking roller or the bag-shaped element and thus abuts at the same time with its entire upper surface against the cutting edge. If at the same time a distinction is made between sawing straight rows as insert cutting, e.g. grinding teeth according to Fig. 18. In the straight part of the group, i.e. at the front of the guide force, the grinding surfaces 39 then come to abut completely against the group.
