Anordning vid vagar. Device for scales.

For upphangning av balanserna vid vagar anvandes vanligen knivformiga eggar med rak kantlinje och pannor med rakt spar. Dylika eggar och pannor krava en omsorgsfull bearbetning, aven for hand, om flagon storre noggrannhet och kanslighet skall kunna uppnas, och stalla sig &afar relativt dyra. De ha darjamte den nackdelen, att man i praktiken aldrig kan uppna den matematiskt noggranna parallellismen mellan eggarna och tillhorande pannor, som teoretiskt erfordras for ernaende av en exakt vagning. For undvikande av dessa olagenheter har man fora foreslagit att anvdnda eggar och pannor av cirkular form, som tangera varandra invandigt. Eggar och pannor av denna form kunna tillverkas genom svarvning eller medelst roterande verktyg och kunna darvid med erforderlig grad av noggrannhet givas sin slutliga form utan bearhetning for hand. De stalla sig darfor mycket billigare i till-verkning, och aven monteringen av desamma forenklas och forbilligas. For hanging the balances at scales, knife-shaped edges with a straight edge line and pans with a straight spade were usually used. Such edges and pans require careful processing, even by hand, if greater accuracy and certainty are to be achieved, and are relatively expensive. They also have the disadvantage that in practice one can never achieve the mathematically accurate parallelism between the edges and associated boilers, which is theoretically required to achieve an exact weighing. To avoid these irregularities, it has been proposed to use edges and pans of circular shape, which touch each other internally. Edges and pans of this shape can be manufactured by turning or by means of rotating tools and can thereby be given their final shape without the required degree of machining with the required degree of accuracy. They are therefore much cheaper to manufacture, and their assembly is also simplified and cheaper.

Gentemot de kanda lagren med raka kniveggar och pannor har ett lager av namnda slag vidare den fordelen, att anliggningen Indian egg och panna blir punktformig, varigenom friktionen i lagret minskas och en storre noggrannhet i avbalanseringen ernas. Darigenom att eggens kantlinje oeh pannans bottenlinje bilda varandra invandigt tangerande cirklar, -vilka ligga i ett mot havarmarna vinkelratt plan, kan det pa eggarna upphangda systemet utfora en viss rorelse i namnda plan utan att havarmsforhallandet forandras och tack vare den punktformiga anliggningen kan aven en viss riirelse i armarnas langdriktning medgivas, varigenom av stotar eller dylikt fororsakade skadliga verkningar climineras. Compared to the known bearings with straight knife walls and foreheads, a bearing of the type mentioned further has the advantage that the bearing Indian edge and forehead becomes point-shaped, whereby the friction in the bearing is reduced and a greater accuracy in the balancing. Because the edge line of the edge and the bottom line of the pan form mutually tangential circles, which lie in a plane perpendicular to the sea arms, the system suspended on the edges can perform a certain movement in the said plane without changing the sea ratio and thanks to the point-like bearing a certain movement in the longitudinal direction of the arms is allowed, thereby eliminating bumps or harmful effects caused by such.

Ur saval tillverknings- som kostnadssynpunkt har det visat sig vara mest andamalsenligt att infasta de eirkuldra eggarna i pressgjutna delar, under det att de cirkuldra pannorna exempelvis fastas 1 av plat pressade delar. Darvid kunna vissa olagenheter uppsta vid sadana vagar, dar balansen resp. vagskalen dr upphangd pa tvenne langs samma svangningsaxel helagna par av dylika lager. Det har namligen visat sig, att yid masstill verkning av dylika vagar ett stort antal vagar kunna uppvisa skillnader i matt mellan eggarnas och pannornas centra av upp till 2 a 3 tiondels mm eller mera. Detta forhallande sammanhanger med den omstandigheten, att eggarna och pannorna ur slitagesynpunkt maste hava sa nara som mojligt lika stora diametrar. Till foljd darav kommer den minsta forskjutning av vagsystemet, som kan uppsta vid ojamn belastning och i synnerhet om lasten flyttas i sidled pa vagskalen, att medfora en avsevard forskjutning av tangeringspunkten mellan egg och panna, sh att denna flyttas i sidled och armed i riktning mot horisontalplanet genom eggens centrum. Harigenom forandras vagens balans- och lagringsfOrhallanden, sa att vagen blir missvisande och i hog grad okanslig. Dennis omstandighet har hittills icke beaktats vid tillverkningen av vagar used cirkulara eggar och pan-nor. Dennis nackdel undanroj es emellertid enligt fOreliggande uppfinning darigenom, att de pa samma svangningsaxel belagna eggarna resp. pannorna aro installbara relativt -varandra i svangningsaxelns riktning. Harigenom har man kunnat uppna en praktiskt taget 100 %-ig sakerhet for att vid fabriksmassig tillverkning av alla vagar bli Uppfinningen skall narmare beskrivas med hanvisning till bifogade ritning. Fig. 1 visar en tvarsektion genom en upphangningsanordning med cirkular egg och tappformig panna enligt uppfinningen. Fig. 2 visar samma anordning, sedd frau sidan med pannan i tvarsektion. Fig. 3 och 4 visa pa motsvarande satt en upphangningsanordning med halvcirkelformig egg och tappformig panna. Fig. 5 är en -vertikalsektion efter linj en V—V i fig. 6 av en vag, forsedd med upphangningsanordningar enligt fig. 1-4. Fig. 6 är en horisontalsektion av vagen efter linjen VI—VI i fig. 5. From both a manufacturing and cost point of view, it has proved most expedient to fasten the cold-cold edges in die-cast parts, while the circular pans, for example, are fastened 1 by flat-pressed parts. Thereby, certain irregularities may arise at such scales, where the balance resp. the scales are suspended on two along the same pivot axis integral pairs of such layers. Namely, it has been found that by mass production of such scales a large number of scales can show differences in matt between the centers of the edges and the foreheads of up to 2 to 3 tenths of a mm or more. This relationship is related to the fact that, from the point of view of wear, the edges and the pans must have as close as possible diameters as large as possible. As a result, the slightest displacement of the weighing system, which can occur at uneven loads and especially if the load is moved laterally on the weighing scale, will result in a considerable displacement of the tangent point between edge and forehead, so that it is moved laterally and armed in the direction of the horizontal plane through the center of the edge. As a result, the balance and storage conditions of the scales change, so that the scales become misleading and highly imperceptible. Dennis' circumstance has so far not been taken into account in the manufacture of scales used circular edges and pans. However, according to the present invention, this disadvantage is obviated by the fact that the edges resp. the boilers are installable relative to each other in the direction of the pivot axis. In this way it has been possible to obtain a practically 100% certainty so that in the case of factory production of all scales, the invention will be described in more detail with reference to the accompanying drawing. Fig. 1 shows a cross section through a suspension device with circular edge and pin-shaped boiler according to the invention. Fig. 2 shows the same device, seen from the side with the boiler in cross section. Figs. 3 and 4 show in a corresponding manner a suspension device with a semicircular edge and a pin-shaped pan. Fig. 5 is a vertical section along line a V-V in Fig. 6 of a vag, provided with suspension devices according to Figs. 1-4. Fig. 6 is a horizontal section of the carriage along the line VI-VI in Fig. 5.

I fig. 1 och 2 betecknar 1 eggen och 2 pannan. Eggen 1 bestar av en ring av hardat staI med cirkuldr kantlinje on triangular tvarsektionsform, vilken an inpressad i ett motsvarande hal i en platta 3, som kan utgOra en fast del av upphangningssystemet. Pannan 2 2- - bestar av en cylindrisk kuts eller tapp av hardat stal, fOrsedd med ett dari insvaryat eirku- tart spar 4 av dubbelkonisk form med betyd- ligt trubbigare vinkel an eggvinkeln. Pannan 2 uppbares av en annan del 5 av upphang- ningssystemet, yid vilken den lampligen kan fastas genom all driyas in i -ett tall passande Ml i delen 5. Den fria anden av tappen 2 har en nagot mindre diameter an eggens 1 inner- kant, sa att tappen latt kan inforas genom det ay eggen bildade halet, medan den innanfor sparet 4 belagna delen av tappen liar en nagot st8rre diameter On eggens haldiameter. Skillnaden mellan tappens diameter i pannans botten och eggens haldiarneter an relativt ringa och kan exempelyis uppga till 1 a 1112 mm. In Figs. 1 and 2, 1 denotes the edge and 2 the pan. The edge 1 consists of a ring of hardened steel with a circular border in triangular cross-sectional shape, which is pressed into a corresponding hall in a plate 3, which can form a fixed part of the suspension system. Boiler 2 2- - consists of a cylindrical cut or pin of hardened steel, Equipped with a dari insvaryat erikutartart spar 4 of double-conical shape with a much more blunt angle than the edge angle. The boiler 2 is supported by another part 5 of the suspension system, in which case it can be suitably fastened by all being driven into a pine fitting M1 in the part 5. The free spirit of the pin 2 has a slightly smaller diameter than the inner edge of the edge 1 , so that the pin can be easily inserted through the tail formed on the edge, while the part of the pin covered inside the groove 4 has a slightly larger diameter on the holding diameter of the edge. The difference between the diameter of the pin in the bottom of the boiler and the holding nets of the edge is relatively small and can, for example, amount to 1 to 1112 mm.

Den i fig. 3 och 4 visade utforingsformen skiljer sig frau den nyss beskrivna endast darigenom, att eggen 6 icke bildar en sluten ring utan an halveirkelformig, varvid upphangningsdelen 3 är forsedd med en slits 7 ay nagot storre bredd an pannans bottendiameter, i andamal all pannan 2 ma kunna inforas i sitt lage pa eggen 6 yertikalt uppifran. The embodiment shown in Figs. 3 and 4 differs from the one just described only in that the edge 6 does not form a closed ring but a semicircular one, the suspension part 3 being provided with a slot 7 having a slightly larger width than the bottom diameter of the boiler, in any case boiler 2 may be inserted into its layer on edge 6 vertically from above.

De i fig. 1-4 visade upphangningsanordningarna kunna giyetvis modifieras pa sadant satt, att eggen anbringas pa den tappfornaiga delen, vapid pannan fir ringformig och ph insidan fOrsedd med en konisk ursyarvning, som bildar sate for eggen. The suspension devices shown in Figs. 1-4 can be modified in such a way that the edge is applied to the pin-shaped part, with the forehead annular and the inside provided with a conical original inheritance, which forms a seat for the edge.

Den i fig. 5 och 6 -visade yagen ar en balansvag med skjutvikter av giingse -t7p. Den bestar av en kapa 10 av rektangular tvarsektionsform med dari anbragta balanser och upphangningsanordningar samt en yagskalshallare 11 av rektangular form och en ph denna lost anbragt yagskal 12. Vagskalshallaren uppbarcs pa i och for sig kant suit av tvenne med varandra sarnverkande balanser 13, 14, vilka aro pa kfint satt forenade med varandra genom en lank 15, som Yid andarna an utbildad till pannor 16, 17, med vilka tvenne pa balanserna fast anbragta kniveggar 18, 19 med raka kantlinjer samverka. Eggarna hallas normalt tryckta mot varandra genom vagskalens och vagskalshallarens egenvikter. Medelst pa ritningen icke visade anordningar av kant slag hindras lanken 15 att forskjuta sig i sidled ur sitt yerksamma lage. Da eggarna 18, 19 och tillhOrande pannor 16, 17 endast upptaga en ringa brakdel ay belastningen ph vagen, behova de ej -vara sa. noggrant bearbetade som de ovriga, vagskalen och belastningen uppbarande, i enlighet med uppfinningen utforda eggarna och pannorna. Naturligtvis kunna a-ven har cirkulara eggar och pannor komma till anyandning, men da balanserna bora hava en viss styrning i sidled, Or det fordelaktigt att anvanda raka eggar och pannor. The yag shown in Figs. 5 and 6 is a balance weight with firing weights of giingse -t7p. It consists of a cap 10 of rectangular cross-sectional shape with balances and suspension devices arranged therein, as well as a yagskall holder 11 of rectangular shape and a ph this loosely arranged yagskal 12. The vagskalshallar is supported on a per se edge suit by two mutually cooperating balances 13, 14, which aro on kfint sat united with each other by a long 15, which Yid the spirits an trained to foreheads 16, 17, with which two on the balances fixed knife walls 18, 19 with straight edges cooperate. The edges are normally held pressed against each other by the dead weights of the cradle shell and the cradle shell holder. By means of devices of the type not shown in the drawing, the link 15 is prevented from displacing laterally from its operative position. Since the edges 18, 19 and associated boilers 16, 17 only take up a small fraction of the load on the road, they do not need to be so. carefully worked as the others, the shell shells and the load bearing, in accordance with the invention challenge the edges and the boilers. Of course, a-ve can have circular edges and pans come to any breathing, but since the balances should have a certain lateral control, it is advantageous to use straight edges and pans.

Balansen 13 bestar av en pi hogkant anordnad plan balk ay plat, som Or anordnad att kunna svanga omkring en vinkelratt mot balken gaende horisontal axel. For detta anda mal Or balansen upphangd i kapan 10 medelst tvenne par ay eggar och pannor 20, 21 resp. 22, 23 ay det i fig. 1 och 2 visade slaget, vilkas verksamma, mot varandra anliggande delar Oro belagna i namnda horisontala syfingnings- axel. Pannorna 21, 23 Oro infasta i vinkel- stycken 24, 25, som i sin tun aro fastade ph insidan av kapan 10, medan eggarna 20, 22 Oro infastade i hal i ena skankeln 26 resp. 27 av tvenne byglar 28, 29, vilka Oro fastade yid balansen 13 pa motsatta sidor av densamma. Andarna av balansen 13 bilda vinkelbockade armar 30, 31, vilka stracka sig at genom hal i kapan 10 och pa framsidan av vagen Ore forenade med varandra medeIst en stang 32, pa vilken en vikt 33 Or forskjutbar. Sistnamnda vikt, som ar forsedd med ett delstreck 34, Or forskjutbar pa stangen 32 langs en skala 35, som Or anbragt ph kapan 10. P0 den ena 30 av namnda armar Or anbragt en medelst en skruv forstallbar tareringsvikt 86, medan den andra armen 31 uppbar en tunga 37, avsedd att samverka med ett fast nollpunktsmarke 38 ph kapan 10. For tareringsandamal finnes darjamte pa kant satt anordnad en stOrre vikt 39, som Or installbar pO. ett i byrseln 29 fast stift 40. The balance 13 consists of a flat beam arranged flat at the right edge, which is arranged to be able to pivot about an angular steering wheel towards the horizontal axis going towards the beam. For this spirit, the balance is suspended in the hood 10 by means of two pairs of edges and pans 20, 21 resp. 22, 23 in the stroke shown in Figs. 1 and 2, the operative, abutting parts of which are arranged in said horizontal axis of sewing. Boilers 21, 23 Oro fastened in angle pieces 24, 25, which in their yard aro fastened ph inside the hood 10, while the edges 20, 22 Oro fastened in slippery in one shank 26 resp. 27 of the two stirrups 28, 29, which Oro fastened to the balance 13 on opposite sides thereof. The spirits of the balance 13 form angularly bent arms 30, 31, which extend through a slide in the hood 10 and on the front of the carriage Ore united with each other by means of a rod 32, on which a weight 33 is displaceable. The latter weight, which is provided with a partial line 34, is displaceable on the rod 32 along a scale 35, which is arranged on the cap 10. On one of the said arms, a tare weight 86 is arranged by means of a screw, while the other arm 31 carried a tongue 37, intended to cooperate with a fixed zero point mark 38 ph kapan 10. For tare purposes, there is also arranged on the edge a larger weight 39, which Or installable pO. a pin 40 fixed in the case 29.

Balansen 14, som likaledes bestar av en i vertikalplanet anordnad plan balk av plat, och som Or belagen mitt under balken 13, Or upphangd i kapan medelst tvenne yertikala lankar 41, 42 samt yid findarna av dessa lankar infastade pannor 43, 44 resp. tvenne pa lanken 42 anbragta pannor, ay vilka endast den owe 45 synes i fig. 6. Namnda pannor aro anordnade att samverka med ringformiga eggar 46, 47 resp. 48, av vilka de under eggarna Oro infastade i den ena skankeln 49 resp. 50 ay tvenne byglar 51 resp. 52, som aro fast anbragta ph motsatta sidor ay balansen 14. De 6yre eggarna 46, 48 Oro insatta i vinkelstycken 53 resp. 54, vilka Oro fast anbragta insidan ay kapan 10. Medelst de undre eggarna och pannorna kan balansen 14 svanga kring en de bada eggarna tangerande horisontal axel. Tack vane lankarna 41, 42 kunna de undre pannorna 44 tvangsfritt installa sig i ratt lage i forhallande till tillhorande eggar, Oven om de Over eggarna icke skulle vara belagna noggrant vertikalt oyanfor de undre. Anordningen medgiver Oven balansen 14 att i nagon man installa sig i sidled i det for Overforing av eggtrycken gynnsammaste laget. The balance 14, which likewise consists of a flat beam of flat arranged in the vertical plane, and which Or is suspended in the middle under the beam 13, Or suspended in the hood by means of two vertical planks 41, 42 and the pans 43, 44 resp. two pans arranged on the lane 42, of which only the owe 45 can be seen in Fig. 6. Said pans are arranged to co-operate with annular edges 46, 47 resp. 48, of which those under the edges Oro fastened in one shank 49 resp. 50 ay two stirrups 51 resp. 52, which are fixedly arranged ph opposite sides of the balance 14. The 6yre edges 46, 48 Oro inserted in angle pieces 53 resp. 54, which are fixedly mounted on the inside of the hood 10. By means of the lower edges and the pans, the balance 14 can pivot about a horizontal axis tangential to the two edges. Thanks to the habit of the lanes 41, 42, the lower pans 44 can forcibly position themselves in a steering wheel position in relation to the associated edges, even if the upper edges would not be coated accurately vertically above the lower ones. The device also allows the balance 14 to position itself laterally in the layer most favorable for the transfer of the egg pressure.

Vagskalshallaren 11 Or yid bada andarna upphangd p5. resp. balanser 13 ocb. 14 forme-deist eggar och pannor ay det i fig. 3 och 4 visade slaget. Vagskalshallaren Or salunda upphangd vid balansen 13 medelst tvenne pannor 55, 56, som Oro infastade i med vagskalshallaren fast forbundna standare 57, 58 samt tvenne halvcirkelformiga eggar 59, 60, som Oro insatta i skanklarna 61, 62 av byglarna 28, 29. Tack vane de yertikala ovanfor eggarna befintliga slitsarna 63 (fig. 5) kunna — — pannorna 55, 56 inforas pa sina platser vertikalt uppifran, varigenom anbringandet och upplyftandet av vagskalshallaren 11 underlattas. For att ytterligare underlatta pannornas infOrande i ratt lage aro styrbleck 64 (fig. 5) anordnade pa skanklarna 61, 62. Pa liknande salt ar vagskalshallaren 11 vid motsatta anden upphangd i balansen 14 medelst pannor 65, 66, anbragta pa vid vagskalshallaren fastsittande standare 67, 68, samt medelst eggar 69, 70, som aro insatta i de med oppna slitsar 71 fiirsedda skanklarna 72, 73. Vagskalshallaren 11 Or yid bada andarna suspended p5. resp. balances 13 ocb. 14 shaped edges and pans of the kind shown in Figs. 3 and 4. Vagskalshallaren Or salunda suspended at the balance 13 by means of two foreheads 55, 56, which Oro fastened in stands 57, 58 firmly connected to vagskalshallaren and two semicircular edges 59, 60, which Oro inserted in the shackles 61, 62 of the stirrups 28, 29. Thank you. the slits 63 (Fig. 5) present above the edges can be inserted into the places 55, 56 vertically from above, whereby the application and lifting of the cradle holder 11 is facilitated. In order to further facilitate the insertion of the boilers in a straight line, guide plates 64 (Fig. 5) are arranged on the shanks 61, 62. On a similar salt, the shell shell holder 11 is suspended in the balance 14 by means of boilers 65, 66, mounted on stands 67 attached to the scale shell holder 67. , 68, and by means of edges 69, 70, which are inserted in the shanks 72, 73 provided with open slots 71.

Vagen bor givetvis vara forsedd med anordningar for att fOrhindra, att vagen kommer i olag vid transport. Detta kan astadkommas pa olika satt, exempelvis sasom visat i fig. 5, dar en vid skankeln 26 fastskruvad stopparm 74 hindrar pannan 21 att hoppa ur eggen 20. I och for ernhende av storsta mojliga noggrannhet och kanslighet ar det av vikt, att pannorna aro noggrant centrerade i horisontal led i forhallande till eggarna. Da vid massfabrikation de olika delarna ej kunna goras sa exakta, att detta utan vidare blir fallet, maste anordningar vidtagas, varigenom centrumavstanden mellan pannorna resp. eggarna kunna justeras. Fir detta andamal kunna exempelvis de pannor 55 och 66, sum sitta i standarna 57 ()eh 68, vara fOrstallbara i sidled genoin anordning av skruvforbindningar 75 resp. 76 och ovala hitl i standarna 57 och 68, sa. att centrumavstanden mellan de samma axellinje liggande tapparna kunna goras noggrant lika med centrumaystanden mellan tillhorande eggar, Pa liknande satt kan pannan 23 vara forstallbar medelst en skruvforbindning 77, sa att dess centrumavstand till pannan 21 kan goras lika med centrumavstandet mellan eggarna 20 och 22. The wagon should, of course, be provided with devices for preventing the wagon from becoming illegal during transport. This can be achieved in various ways, for example as shown in Fig. 5, where a stop arm 74 screwed to the shank 26 prevents the boiler 21 from jumping out of the edge 20. In order to obtain the greatest possible accuracy and probability, it is important that the boilers are carefully centered horizontally in relation to the edges. Since in mass production the various parts cannot be made so precise that this is the case without further ado, devices must be taken, whereby the center distance between the boilers resp. the edges can be adjusted. For this purpose, for example, the boilers 55 and 66, which sit in the stands 57 () eh 68, can be formed laterally by means of a device of screw connections 75 and 75, respectively. 76 and oval hitl in stands 57 and 68, sa. similarly, the center distance between the same shaft line pins can be made exactly equal to the center distance between associated edges. Similarly, the boiler 23 can be adjustable by means of a screw connection 77, so that its center distance to the boiler 21 can be made equal to the center distance between the edges 20 and 22.

Vagning sker pa kant satt genom nollinstallning av balansen 13 medelst vikten 33. Det ãr av vikt, att anliggningsstallena mellan eggarna och pannorna 59, 55 resp. 20, 21 resp. 18, 16 ligga pa samma horisontallinje, nar halansen befinner sig i silt nollage. Weighing is done on the edge set by zero installation of the balance 13 by means of the weight 33. It is important that the abutment positions between the edges and the pans 59, 55 resp. 20, 21 resp. 18, 16 lie on the same horizontal line when the tail is in zero position.
