Description

Uppfinnare: H W Aldrin Foreliggande uppfinning hanfor sig till en anordning vid t. ex. kanontorn for uppfordring av patroner till kanonen fra'n ett under denna befintligt ammunitionsforrad, vilken anordning är av det slag, som omfattar en for styrning av patronerna i deras langdriktning inrattad, vasentligen vertikal kanal och en hissanordning for frammatning av patronerna efter varandra genam denna kanal. Inventor: H W Aldrin The present invention relates to a device for e.g. the cannon tower for urging cartridges to the cannon from an ammunition supply existing below it, which device is of the type comprising a substantially vertical channel arranged for guiding the cartridges in their longitudinal direction and an elevator device for advancing the cartridges one after the other through this channel. .

Hittills kanda ammunitionshissar med motordrivna kedjor eller hydrauliskt drivna skjutstanger ger en relativt langsam rorelse och anvandas for samtidig stegvis frammatning av flera patroner, som Mier tatt eller varandra i den vertikala tillforselkanalen. Uppfinningen liar till syfte att undanrOja de med sadana hissar forenade olagenheterna och att astadkomma en sa snabb uppfordring, att endast en patron at gangen behover befinna sig i den vanligen raft langa kanalen mellan ammunitionsforradet och ppsen. Vi-dare ger uppfinningen en mojlighet att aven vid relativt Tanga tra:nsportvagar halla uppfordringsmekanismen mom rimliga proportioner. Uppfinningen liar liven till syfte att losa problemet att pa ett enkelt och praktiskt satt fa en onskad jamn retardation av patronens rarelse vid overanden av den styrande kanalen. Ytterligare en fOrdel ailed uppfinningen ãr att aven vid nederanden av den styrande kanalen, vid vilken ande patroller skill inmatas, Or rorelsehastigheten hos det medbringande organet lag i forhallande till genomsnittshastigheten. Detta medfOr hi. a. att drivorganets stoppmekanism, for t. ex. styckvis frammatning av patroner, kan utforas med relativt vida toleranser. Uppfinningen mojliggor dessutom att drivorganet endast behover ha ett stopplage per uppfardringscykel, lampligen vid nederanden av den styrande kanalen, .och salunda Or flagon anordning for omkastning av rorelseriktningen hos drivorganet far Overanden av kanalen ej erforderlig. Hitherto known ammunition lifts with motor-driven chains or hydraulically driven push rods provide a relatively slow movement and are used for simultaneous stepwise advancement of several cartridges, which Mier has taken or each other in the vertical supply channel. The object of the invention is to obviate the nuisances associated with such elevators and to provide such a rapid request that only one cartridge at a time needs to be in the usually very long channel between the ammunition supply and the pps. Furthermore, the invention makes it possible, even in the case of relatively Tanga transport carriages, to maintain the urging mechanism in reasonable proportions. The object of the invention is to solve the problem of obtaining in a simple and practical manner a desired even deceleration of the pattern of the cartridge at the overhang of the control channel. A further advantage of the invention is that even at the lower ends of the guiding channel, at which spirit patrols are fed, the speed of movement of the entraining member is in relation to the average speed. This entails for hi. a. that the stop mechanism of the drive means, for e.g. piecemeal feed of cartridges, can be performed with relatively wide tolerances. The invention furthermore makes it possible that the drive means only need to have one stop bearing per drive cycle, suitably at the bottom of the guiding channel, and thus the device for reversing the direction of movement of the drive means does not require the upper end of the channel.

Enligt uppfinningen uppnas dessa syften darigenom, att en i hissanordningen ingaende, utmed kanalen styrd slade, avsedd att med ett I kanalen inskjutande utsprang verka mot patronernas st6tbotten, Or anordnad att me-deist ett system av svangande havarmar bibringas en fram- och Atergaende rorelse melIan. sina andlagen. Varje gang de svangande havarmarna vaxlar rOrelseriktning star sladen i ettdera av sina andlagen, och eftersom de svangande armarna utan sarskilda atgarder avsaktar sin rorelse innan denna omkastas, far man for sladen och armed Oven for patronen autematiskt en rorelse, som i genomsnitt kan vara hastig men som accelereras och retarderas Over en. stor del av banan, sa att massakrafterna joke Overskrider relativt begransade varden. According to the invention, these objects are achieved in that a sledge entering the elevator device, guided along the channel, intended to act with a projection projecting into the channel against the strut bottom of the cartridges, Or arranged to impart a reciprocating movement between a system of swinging sea arms . their spirits. Each time the swinging arms swing in the direction of movement, the swing stands in one of its spirits, and since the swinging arms without special action slow down their movement before it is reversed, the stroke and armed Oven for the cartridge automatically cause a movement, which on average can be rapid but which is accelerated and decelerated Over one. large part of the orbit, said that the mass forces joke Exceeds relatively limited cairn.

Vid en praktisk utforingsform av uppfinningens huvudtanke Or sladen ledbart fast vid anden av en lank, som i sin fur Or ledbart fast vid .ena armen av en i vertikalplanet rorlig havstang, vilken Or lagrad pa en vridtapp, sam Or anordnad att drivas frana och tillbaka I en cirkelbagformig bana, varjamte linden av havstfingens andra arm ár styrd i en kurva som mojliggor den anskade rOrelsen hos sladen. In a practical embodiment of the main idea of the invention, the blade is hingedly attached to the spirit of a long shaft, which in its fur is hingedly attached to one arm of a sea rod movable in the vertical plane, which is mounted on a pivot pin, which is arranged to be driven back and forth. In a circular bag-shaped path, the linden of the other arm of the sea-finger is guided in a curve which enables the desired movement of the sled.

Det angivna sattet att driva sFaden Or fOrdelaktigt Oven ur den synpunkten, att det vOl lampar sig for anvandning vid en kanal for patronerna, vilken Or krokt. I enlighet med ett sekundart kannetecken pa uppfinningen Or salunda patronkanalen, som vid tivre fin-den Or vertikal, utbildad kr8kt och i riktning nedat dragen alltmera bort frau vertikallinjen, och liar namnda kanal en snett lutande undre del, utmed vars undersida slb.den Or 2—— styrd, varjamte kanalen vid underanden och ph den mot sladstyrningen motsatta, oversidan her en oppning, genom vilken patroller kunna i lutande lage inforas i kanalen. Data kannetecken for med sig den fardelen, att hanteringen vid inmatningen av patronerna underlattas. The stated method of operating the cartridge is advantageous from the point of view that it would be suitable for use with a channel for the cartridges, which is curved. In accordance with a secondary cue sign of the invention, the cartridge channel, which at the lower end is vertical, formed curved and in the downward direction is increasingly pulled away from the vertical line, and said channel has an obliquely inclined lower part, along the underside of which 2—— controlled, with the channel at the bottom and ph the opposite of the cable guide, the upper side here an opening, through which patrols can be introduced into the channel in an inclined position. Data can carry with it the advantage that handling when feeding the cartridges is facilitated.

Ytterligare kannetecken pa uppfinningen framgar av efterfoljande beskrivning, vani hanvisas till bifogade ritningar, som visa tvá foredragna utforingsformer av ammunitionstillforingsanordningen enligt uppfinningen. Fig. 1-4 hinfor sig till en farsta utforingsform, vilken i fig. 1, 2 och 3 visas perspektiviskt snett framifran vanster och i tre olika arbetslagen, medan fig. 4 är en snett framifran h8ger tagen vy. Fig. 5 visar en. sektion tagen efter linjen VI—VI i fig. 1. Fig. 6 dr en. mot fig. 1 svarande vy av ett modifierat utforande. Further features of the invention will become apparent from the following description, taken in conjunction with the accompanying drawings, which show two preferred embodiments of the ammunition supply device according to the invention. Figs. 1-4 refer to a first embodiment, which in Figs. 1, 2 and 3 is shown in perspective obliquely from the front left and in three different working layers, while Fig. 4 is an oblique front view taken from the right. Fig. 5 shows a. section taken along the line VI — VI in Fig. 1. Fig. 6 dr en. Fig. 1 is a view of a modified embodiment.

Den pa ritningarna visade ammunitionsuppfordringsanordningen är avsedd att anvandas vid sadana t. ex. pakrigsfartyg eller i fort farekommande vridbara kanontorn, som under pjasen innehaller ett farrad av ammunition, som patron efter patron skall matas upp far att inforas i eldroret. Sjalva kanontornet visas icke pit ritningarna, men fig. 1 visar den. darpa monterade kanonen 1 med dess elevationstappar 2. Fran det undre rummet i kanontornet leder en rorformig kanal 3 (fig. 1 och 5) upp till en kring tappar 4 svangbar laddbrygga eller pendel 5, som tjanar till att iiverfora en fran overanden av kanalen 3 utmatad patron fran vertikalt lage till lampligt vinkellage for inforande i eldraret. Kanalen 3 hr upptill vertikalt eller na.stan vertikalt riktad, men kroker t. ex. efter en cirkelbagformig kurva, sâ att den i riktning nedat alltmera avlagsnar sig fran vertikallinjen genom den ovre delen av kanalen. Understa delen lutar salunda i en vinkel av t. ex. 0 mot vertikallinj en. Vid underanden ãr kanalen uppskuren pa aversidan, sit att en. oppning bildas, genom vilken: patroner kart inforas kanalen. Sasorn visas i fig. 1, korruner en genom denna oppning inford patron. 6 att genom sin tyngd vila mot den. motsatta undersidan av kanalen. For att styra den inmatade patronen 6 och hindra att den reser sig vid barjan av uppfordringen Or en matarvals 7 med korsformad tvarsektion anordnad att delvis tacka den i undera.nden av kanalen 3 upptagna oppningen. I anslutning till namnda inmatningsoppning kan ett magasin, som rymmer ett antal patroner vara utbildat. Detta magasin bildas av tva motstaende fallbara lister 8, 9, som stodjer patronerna fran sidorna, och en daremot vinkelratt riktad vagg 10, mot vilken patronernas bottnar glidande stadia vid nedmatningen. Dessa lister 8, 9 hindrar aven langsforskjutning av patronerna innan de konunit ned i kanalen 3. Tva stora plana vaggplatar 11, 12 bildar en. kapa for rarkanalen 3 och den nedan narmare beskrivna ro relsemekanismen. PA dessa platar kan halm 13 (fig. 4) for ett farstahandslager av patroner vara fastsatta, fran vilket lager man myeket latt kan plocka ned patroner i inmatningsoppning, sdsom fig. 4 visar. The ammunition requesting device shown in the drawings is intended to be used in such e.g. pack warships or in rapidly dangerous rotating cannon towers, which during the play contain a barrage of ammunition, which cartridge after cartridge is to be fed up to be introduced into the barrel. The cannon tower itself is not shown in the pit drawings, but Fig. 1 shows it. darpa mounted the cannon 1 with its elevation pins 2. From the lower space of the cannon tower a rudder-shaped channel 3 (Figs. 1 and 5) leads up to a charging bridge or pendulum 5 pivotable about pins 4, which serves to transfer one from the upper part of the channel 3 discharged cartridge from vertical bearing to suitable angular bearing for insertion into the firebox. The channel 3 hr at the top vertically or almost vertically directed, but hooks e.g. following a circular bag-shaped curve, so that in the downward direction it increasingly deviates from the vertical line through the upper part of the channel. The lower part tilts salunda at an angle of e.g. 0 to the vertical line. At the bottom, the channel is cut on the upper side, sit that one. opening is formed, through which: cartridges map are introduced into the channel. The saw is shown in Fig. 1, corroding a cartridge inserted through this opening. 6 to rest against it by its weight. opposite the underside of the channel. In order to guide the fed cartridge 6 and prevent it from rising at the beginning of the call, a feed roller 7 with a cross-shaped cross section is arranged to partially thank the opening accommodated in the lower part of the channel 3. In connection with the said feed opening, a magazine, which holds a number of cartridges, can be formed. This magazine is formed by two opposite collapsible strips 8, 9, which support the cartridges from the sides, and a rocker 10 directed at right angles to it, against which the bottoms of the cartridges slide during the feeding. These strips 8, 9 also prevent longitudinal displacement of the cartridges before they merge into the channel 3. Two large flat cradle plates 11, 12 form one. cut for the pipe channel 3 and the stirring mechanism described in more detail below. On these plates, straw 13 (Fig. 4) for a first hand layer of cartridges can be attached, from which layer cartridges can be very easily picked down in the feed opening, as Fig. 4 shows.

Det som styrningskanal f5r patronerna tjanande raret 3 har efter sin undersida en langsgh.ende slits 14 (fig. 5) och i anslutning till denna är anordnad en i form av tvit i profil hakformigt b8jda lister 15, 16 utbildad styrgejd, som stracker sig utefter roret och Mier dess loaning. I derma styrgejd är en. parullar 17 liipande slade 18 forskjutbar. Vid sladen Or fast en medbringare 19, sam genom slitsen 14 skjuter in i kanalen 3 och darigenom kan medbringa en patron i kanalen genom att verka mot dess statbotten. Fig. 1 visar sladeni 1 dess undre andlage, i vilket medbringaren 19 är ford ned bakom statbottnen av den fran magasinet till styrkanalen 3 overfarda patronen 6. Fig. 2 visar ett senare lage, i vilket sladen matat upp patronen ett stycke genom kanalen, och fig. 3 visar sladen i narheten av dess aversta lage, i vilket patronen matats ut genom kanalens Overande och overforts till laddningspendeln 5. Medbringaren 19 ar svangbart anordnad och star lampligen under fjaderpaverkan, sit •att den fares undan nar sladen vid slutet av atergangsrorelsen passerar en patron, som under tiden tagit den foregaende patronens plats vid kanalens underande och till sist kan snappa in bakom derma patrons botten. Slit-den uppbar vidare en svangbar kb o 20 (fig. 3), som samtidigt griper am patronflansen och som fasthaller patronen vid sladen under dennas retardation vid slutet av den uppatgaende rorelsen. Denna kb o frigores pa ett har icke narmare beskrivet salt frail patronen nar denna Overforts till pendeln 5, sit att sladen bar fri att git tillbaka ned mot inmatningslage. The guide channel 3 serving as a guide channel for the cartridges has a longitudinal slot 14 (Fig. 5) after its underside, and in connection therewith a guide guide formed in the form of a hook in profile in a hook-shaped bend 15, 16, which extends along roret and Mier its loaning. In this guide is one. parullar 17 liipande slade 18 displaceable. Attached to the sled Or is a carrier 19, which through the slot 14 projects into the channel 3 and thereby can carry a cartridge in the channel by acting against its state bottom. Fig. 1 shows the sledge 1 in its lower abutment, in which the carrier 19 is driven down behind the state bottom of the cartridge 6 passing from the magazine to the guide channel 3. Fig. 2 shows a later layer, in which the sledge feeds the cartridge a bit through the channel, and Fig. 3 shows the sledge near its lowest layer, in which the cartridge is discharged through the channel overhang and transferred to the charging pendulum 5. The carrier 19 is pivotally arranged and stands suitably under the spring influence, so that it moves away when the sledge passes at the end of the return movement a cartridge, which in the meantime has taken the place of the preceding cartridge at the bottom of the channel and can finally snap in behind the bottom of this cartridge. The wear further carried a pivotable kb o 20 (Fig. 3), which simultaneously grips the cartridge flange and which holds the cartridge to the sled during its deceleration at the end of the upward movement. This kb o is released on a has not further described salt frail the cartridge when this Overforts to the pendulum 5, sit that the sled was free to go back down towards the feed mode.

Mekanismen, som driver sladen i dess beskrivna bana Or vasentligen placerad i det av platarna 11, 12 inneslutna utrymmet vid underanden av kanalen 3. I denna meka.nism ingar en serie ledbart vid varandra forbundna, fram och Ater svangande armar eller stanger, namligen en lank 21, en. tvaarmad havstang 22-23 och en gaffel 24. Drivkraften erhalles fran en motor 25, som over en. koppling 26 — inrattad att vid impuls tillslas for att efter ett vary ev. Ater kunna franslas och lasas av en .magnetbroms — driver en vev 27, som medelst en lank 28 Sr kopplad med en. vev 29 .fastsatt pa en i stativet lagrad axel 30. Pa andra anden av denna axel 30 Or gaffeln 24 fastsatt. Nyssnananda vevar Or sit dimensionerade, att axeln 30 vrider sig c:a 600 i ena rotationsriktningen och sedan vander ,och gar tillbaka till utgangslaget for varje gang veven. 27 roterar ett vary. Gaff em 24 svanger darvid i vertikalplanet frit' det i fig. 1 visade undre andlaget till ett ovre andlage ungefar motsvarande laget enligt fig. 3 och sedan tillbaka — —3 3 till utgangslaget. De bada andlagena av gaffelns rorelse motsvarar dodpunkterna for vevrOrelsen, i vilka dodpunkter veven 27 och lanken 28 ligger i linje med varandra, och det ãr tydligt att vid konstant rotationshastighet hos motorn, kommer gaffelns rorelse att igangsattas mycket mjuk_t och accelereras, varefter rorelsen retarderas tills dess riktning omkastas, da rorelsen alter forst accelereras och sedan retarderas. Gaffeln 24 kan lampligen utforas krokt for att dess fria ande skall kunna svanga in bakom kanalen 3 och inta laget enligt fig. 3. The mechanism which drives the sled in its described path is substantially located in the space enclosed by the plates 11, 12 at the lower end of the channel 3. In this mechanism a series of articulated interconnected, forward and rearwardly swinging arms or rods, namely a lank 21, en. heated sea rod 22-23 and a fork 24. The driving force is obtained from an engine 25, which over one. coupling 26 - designed to be switched on in the event of an impulse in order to vary after a Again can be frayed and locked by a .net magnetic brake - drives a crank 27, which by means of a lank 28 Sr connected to a. crank 29 .attached on a shaft 30 mounted in the frame. On the other end of this shaft 30 Or the fork 24 fixed. Nyssnananda cranks Or sit dimensioned, that the shaft 30 rotates about 600 in one direction of rotation and then turns, and returns to the starting position for each time the crank. 27 rotates a vary. Gaff em 24 then swings in the vertical plane freely the lower end shown in Fig. 1 to an upper end approximately corresponding to the layer according to Fig. 3 and then back to the starting layer. The two aspects of the fork movement correspond to the dead centers of the crank movement, in which the dead points of the crank 27 and the tongue 28 are in line with each other, and it is clear that at a constant rotational speed of the motor, the fork movement will be initiated very smoothly and accelerated. its direction is reversed, as the motion alter is first accelerated and then retarded. The fork 24 can suitably be made crooked so that its free spirit can swing in behind the channel 3 and take in the layer according to Fig. 3.

Den tvaarmade havstangen 22-23 är sva.ngbar i vertikalplanet kring en tapp 31, som är insatt radian andarna av gaffelns 24 hada skanklar. Gaffeln 24 ar sa tang, att havstangsarmen 22 kan passera mellan dess skanklar. 'Aitken 21, som ocksa är rorlig i ett vertikalplan, ãr Iedbart forbunden dels med sladen 18 och dels med anden av havstangsarmen 2.2. Sasom visas av fig. 1, kan dven lanken 21 delvis dragas in mellan skanklarna av gaffeln 24. Anden av ha.vstangens andra arm 23 ar med railer 32 styrd i tva likformiga motstaende styrspar 33, 34, som ar utbildade pa insidorna av platarna 11 resp. 12. Dessa spar ha upptill en vasentligen vertikal strackning och aro med undre andarna dragna snett neat och bort frail axeln 30. Havstangens r8relse är helt bestamd av gaffeln 24 och styrsparen 33, 34, 1 det att dess vridpunkt (ta.ppen 31) beskriver en cirkelbagformig bana och all-tid intar ett Idge, som är bestamt endast av gaffelns 24 Idge, medan styrsparen tjana till att styra havstangens -vridningsrorelse kring tap-pen 31. 1 utgangslaget enligt fig. 1 ãr haystangen 22-23 ungefar horisontell, och vid svdngning av gaffeln 24 motsols reses hairstangen alltmera (se fig. 2) for att i vandlaget (ungefar motsvarande fig. 3) bli vasentligen vertikalt riktad. Anden av armen 22 fares uppat dels genom denna uppresning av haystangen, dels genom att dess vridpunkt forskjutes uppat. Sladen bibringas en annu langre och snabbare rorelse uppat, genom att Milken 21, som forbinder sladen med namnda ande av havstangsarmen 22, ocksa uppreses fran det i fig. 1 visade sneda laget till det I fig. 3 visade vertikala Idget. I den man som vinkeln mellan armen 22 och lanken 21 utratas och dessa delar blir vertikalt riktade, minskas den rorelsekomponent hos sladen, som harror fran den namnda uppresningen, vilket innebar att sladen ror sig betydligt Langsammare vid den ovre an vid den nedre vandpunkten. The two-armed sea rod 22-23 is pivotable in the vertical plane around a pin 31, which is inserted into the radius of the spirals of the fork 24's shins. The fork 24 is so tangled that the sea rod arm 22 can pass between its shanks. 'Aitken 21, which is also movable in a vertical plane, is Iedbart connected partly with the sled 18 and partly with the spirit of the sea rod arm 2.2. As shown in Fig. 1, the dowel 21 can be partially retracted between the shanks of the fork 24. The spirit of the second arm 23 of the sea rod is guided by rails 32 in two uniform opposite guide pairs 33, 34 formed on the insides of the plates 11. resp. 12. These spades have a substantially vertical tension at the top and are with the lower spirits pulled obliquely neat and away from the shaft 30. The movement of the sea rod is completely determined by the fork 24 and the guide spears 33, 34, 1 that its pivot point (pin 31) describes a circular bag-shaped path and always occupies an Idge, which is determined only by the fork 24 Idge, while the guide pairs serve to control the rotational movement of the sea rod around the pin 31. In the output layer according to Fig. 1, the hay rod 22-23 is approximately horizontal, and when turning the fork 24 counterclockwise, the hairpin is raised more and more (see Fig. 2) in order to be substantially vertically directed in the water layer (approximately corresponding to Fig. 3). The spirit of the arm 22 is raised upwards partly by this raising of the haystack, partly by displacing its pivot point upwards. The sled is imparted an even longer and faster upward movement, in that the Milken 21, which connects the sled with the said spirit of the sea rod arm 22, is also raised from the oblique layer shown in Fig. 1 to the vertical Idget shown in Fig. 3. In the man whose angle between the arm 22 and the tongue 21 is eradicated and these parts become vertically directed, the movement component of the sled, which harrows from the said erection, is reduced, which meant that the sled moves much slower at the upper end at the lower water point.

Utforandet enligt fig. 6 overensstammer 1 stort med det ,ovan beskrivna men avviker darifran genom att den dar forefintliga krokta gaffeln 24 är ersatt av en rak arm 35, som är nagot forskjuten at sidan for att kunna ga forbi patronmagasinet vid sin uppatsvangRing och icke vara i vagen for havstangens 22. —23 uppresning. Vidare svanges denna arm 35 joke medelst en motordriven vev utan me-deist en i stativet ledbart infast hydraulisk cylinder 36, vars kolvsta.ng ar ledbart fast vid ett utsprang 37 pa armen 35. The embodiment according to Fig. 6 is very similar to the one described above, but differs from it in that the existing crooked fork 24 is replaced by a straight arm 35, which is slightly offset to the side in order to be able to pass the cartridge magazine during its uptake and not be i vagen for havstangens 22. —23 uppresning. Furthermore, this arm 35 joke is pivoted by means of a motor-driven crank without a hydraulic cylinder 36 which can be articulated in the frame and whose piston rod is articulated and fixed at a projection 37 on the arm 35.
