M. M. JOHNSON, JR., BROOKLINE, MASS., AMERIKAS FORENTA STATER. Avfyringsmekanism for automatvapen. M. M. JOHNSON, JR., BROOKLINE, MASS., UNITED STATES OF AMERICA. Automatic firing mechanism.

FOreliggande uppfinning avser avfyrningsmekanismen vid automatvapen, sarskilt kulsprutegevar for militart bruk. Vid uppfinningsforemalet kan varje slags slutstyckemekanism anvandas. The present invention relates to the firing mechanism of automatic weapons, in particular machine guns for military use. In the object of the invention, any kind of bolt mechanism can be used.

Huvudforemal for uppfinningen as att a.stadkomma en avfyrningsmekanism av enkel och billig konstruktion, som iir tillforlitlig och varaktig, som latt kan hopsattas och sondertagas, som hastigt och latt kan omstallas fran sakrat tillstand, vid vilket eldhandvapnet ej kan avfyras, till endera automatisk eller patronvis eld, som later slutstycket forbli i slutet lage efter -varje med patronvis eld avgivet skott och som fasthaller slutstycket i tillbakadraget lage efter automatisk eld. The main object of the invention is to provide a firing mechanism of simple and inexpensive construction, which is reliable and durable, which can be easily assembled and probed, which can be quickly and easily converted from a secluded state, in which the firearm cannot be fired, to either automatic or cartridge-like fire, which leaves the bolt in the end layer after each shot fired and which holds the bolt in the retracted shaft after automatic fire.

Uppfinningen omfattar en anordning for att fasthalla slutstycket i tillbakadraget 'age efter automatisk eldgivning, varigenom f a-ran for oavsiktlig explosion av patronens drivladdning undvikes, vilken explosion el-jest skulle kunna uppsth nar en patron kvarlamnas i ett upphettat patronlage, jamte organ for att Ora fasthallningsorganen overksamma vid patronvis eld, sa att slutstycket är reglat fore siktiningen och eldgivningen samt forblir i reglat Lige mellan skotten. Det senare organet besthr av en handmanovrerad omstallare, vilken är installbar i lagen for automatisk eller patronvis eld, och som lampligen aven är installbar i ett sakrande lage, i vilket eldgivning forhindras. Gevaret kan aven vara fOrsett med en utlosare som är paverkbar av slutstyckets rorelse fran Oppet till slutet läge, varigenom hammaren utilises. Ut16- saren manovreras aven av omstallaren, sh att utlosaren fungerar, da omstallaren befinner sig i lage for automatisk eld men är satt us funktion,omstallaren befinner sig i lage fOr patronvis eld. The invention comprises a device for holding the bolt in the retractable position after automatic firing, thereby avoiding the risk of unintentional explosion of the cartridge propellant charge, which explosion could otherwise occur when a cartridge is left in a heated cartridge layer, or means for The holding members are inactive in the event of a cartridge-like fire, so that the bolt is regulated for sighting and firing and remains in control straight between the shots. The latter means consists of a hand-operated switch, which is installable in the law for automatic or cartridge-like fire, and which is suitably also installable in a sacrificial layer, in which firing is prevented. The rifle can also be provided with a trigger which is affected by the movement of the bolt from the Open to the closed position, whereby the hammer is used. The switch is also maneuvered by the switch, so that the trigger works, as the switch is in position for automatic fire but is set to function, the switch is in position for cartridge fire.

The rear end of the actuator P has a longitudinally sliding bore 42 in which Or inserts a buffer piston 43, which is retained by a stud 44, which protrudes into a recess 46 ph the side surface of the piston, saint a buffer spring 47, which normally holds the piston in its rear bearing. as shown in Fig. 8. When the bolt recoils, the narrower rear end of the maneuvering piece P in the above-mentioned For slides into the piston 6, and the buffer piston 43 faces the inside of the screw cap 7.

Verkningssattet beskrives med ledning av fig. 15 pa foljande sad: DO gevaret avskjutes, rara sig pipan 1, slutstycket B och manoverstycket P tillsammans bakat, tills pipans bakre ande stater ,emot anslagsytan 2. Under denna korta rarelse griper kamytan 19 in mot den motsvarande kamytan pa mekanismladan, varvid slutstycket vrides motsols till uppreglat lage, i vilket rullen 21 hammer mitt for sparet 22, och klackarna 13 pa slutstyckets huvud komma mitt for mellanrummen mellan klackarna 14 ph pipan. Av sin troghet fortsatta slutstycket och manoverstycket P till sina bakre andlagen. DO Grater manoverstycket P av manoverfja.dern RS fares framat, slar kamytan 24 an mot kamytan 18 ph slutstycket, varigenom detta vrides medsols till reglat lage, sedan rullen 21 lamnat framanden av sparet 22, och slutstyckets klaekar 13 passerat mei- — —a Ian pipans klackar 14. Avfyrningsmekanismen bestar av en avtryekare T, som Sr svangbart lagrad i underbeslaget R' pa en bult 48, som sticker ut genom oppningar 49 i tva uppstaelide arm 51 pa avtryckaren och genomgar nnderbeslagets R' sidovaggar (fig. 10 on 11). Avtryckaren Sr IA sin Nanstra sida fOrsedd med en framatriktad forlangning 52, vilken griper in mot .ena grenen 53 av en tvagrenad bladfjader 54 (fig. 12 och 13). Avtryckaren liar vid sin bakre ande en bakatvand klack 56 (fig. 22) med en baked riktad andyta 57, varvid klackens vanstra sida Sr avfasad vid 58 f Or att minska avtryckarens vikt (fig. 22). Avtryckarens ovre yta Sr snedskuren vid 59 for att lamna plats for en del av avtryckarstangen, sasom nedan skall beskrivas. Avtryckarens av fjadern 53 framkalla-de svangningsrorelse kring 48 begransas av en ansats (51 pa underbeslaget R' (fig. 10). The mode of action is described with reference to Fig. 15 in the following manner: DO the vessel is fired, the barrel 1, the bolt B and the control piece P are baked together, until the rear end of the barrel, against the abutment surface 2. During this short movement the cam surface 19 engages against the corresponding the cam surface of the mechanism barrel, the bolt being turned counterclockwise to the raised bearing, in which the roller 21 hammers in the middle of the groove 22, and the lugs 13 on the head of the bolt come in the middle of the spaces between the lugs 14 ph the barrel. Out of their loyalty, the end piece and the maneuver piece P continued to their hindquarters. DO Grater the maneuvering piece P of the maneuvering spring RS is moved forward, the cam surface 24 strikes the cam surface 18 ph the bolt, whereby this is turned clockwise to the control bearing, after the roller 21 has left the front of the groove 22, and the bolt 13's have passed with barrel lugs 14. The firing mechanism consists of a trigger T, which is pivotally mounted in the lower fitting R 'on a bolt 48, which protrudes through openings 49 in two raised arms 51 on the trigger and passes through the side walls of the lower fitting R' (fig. 10 on 11) . The trigger Sr IA has its Nanstra side provided with a forwardly directed extension 52, which engages against one branch 53 of a two-branch leaf spring 54 (Figs. 12 and 13). At its rear end, the trigger has a rearward-facing heel 56 (Fig. 22) with a bent-directed end face 57, the left side Sr of the heel being chamfered at 58 f Or to reduce the weight of the trigger (Fig. 22). The upper surface of the trigger is cut obliquely at 59 to leave space for a part of the trigger rod, as will be described below. The oscillating motion of the trigger of the spring 53 about 48 is limited by a shoulder (51 on the lower fitting R '(Fig. 10).

En avtryckarsparr TR Sr svangbar kring en bult 62 i underbeslaget och fOrsedd med en nä-so 63, som griper in mot den bakatriktade andytan 57 p5 avtryckaren for att forhindra oavsiktlig rorelse hos avtryckaren. Avtryckarsparren TR Mlles- i det a. fig. 8 och 9 visade verksamma laget medelst en fjader 64, som verkar mot baksidan av -ett finger, som sticker ut genom en oppning i handgreppets 4 framsida. handgreppet 4 fattas for avfyrning av gevaret, fares genom handens fattning om clef utsthende fingret avtryekarsparren TR automatiskt tillbaka till overksamt lage. A trigger guard TR Sr is pivotable about a bolt 62 in the lower fitting and provided with a nose socket 63 which engages against the rearwardly facing end face 57 of the trigger to prevent accidental movement of the trigger. The trigger guard TR Mlles- in the active team shown in Figs. 8 and 9 by means of a spring 64, which acts against the back of - a finger, which protrudes through an opening in the front of the handle 4. the handle 4 is taken for firing the rifle, is passed through the grip of the hand if the clef protrudes the finger the trigger guard TR automatically returns to inactive position.

I mellanrummet mellan de bagge uppstaende broiler,. 51 pa avtryckaren Sr avtryckarstangen S svangbart anordnad pS bulten 48 (fig. 8, 9 och 10) for att medsols svangas frail det rage, i -vilket den lasthaller hammaren till ett framre lage, i vilket hammaren frigives. Avtryckarstangen liar i ovre delen tvenne hakar 67 och 68 far ingrepp med motsvarande hakar pa hammaren H, varvid haken 67 hailer hammaren i tillbakadraget lage, da avtryckaren befinner sig i normalt lage, medan haken 68 fasthaller hammaren, om avtryckaren befinner sig i tillbakafort laze, da hammaren Sr spand. Comhammaren griper in i ha-ken 68, sa kopplar den automatiskt Over till haken 67, om avtryckaren friges. Avtryckarstangen Mlles eftergivande i normalt lage, sas.om fig. 8, 9 och 10 visor, medelst en fja-der 69, som utgor den andra grenen av ovannamnda tvagreniga bladfjader 54. For eld patronvis frikopplas avtryckarstangen ur ingrepp med slaghammaren .darigenom att ytan 71 av a.vtryckaren (fig. 22) trycker uppat mot den bakre anden av avtryckarstangens undre yta. Sfisom fig. 9 visar, finnes .ett avsevart glapprum Indian dessa bagge far samverkan med -varandra avsedda ytor, sa att avtryckaren kan foras tillba,ka ett kort stycke utan att paverka avtryekarstangen. Da delarna aro installda for automatisk .eld, begransar en stoppanordning avtryckarens rarelse bakat till det lage, som visas pa fig. 10, i vilket lage -avtryckareti kommit i kontakt med avtryckarstangen men annu ej forskjutit densamma. In the space between the ram standing broiler ,. 51 on the trigger, the trigger rod S is pivotally arranged on the bolt 48 (Figs. 8, 9 and 10) so that it is pivoted clockwise from the rage in which it loads the hammer to a front bearing in which the hammer is released. The trigger rod is in the upper part two hooks 67 and 68 engage with corresponding hooks on the hammer H, the hook 67 holding the hammer in the retracted position, when the trigger is in the normal position, while the hook 68 holds the hammer, if the trigger is in the retracted position, da hammaren Sr spand. The comhammer engages the hook 68, then it automatically switches Over to the hook 67, if the trigger is released. The trigger rod Mlles yields in the normal position, as shown in Figs. 8, 9 and 10, by means of a spring 69, which forms the second branch of the above-mentioned two-branch leaf spring 54. 71 of the trigger (Fig. 22) presses upwards against the rear end of the lower surface of the trigger rod. As shown in Fig. 9, there is a considerable gap space between these rams in interaction with the intended surfaces, so that the trigger can be brought back, a short distance without affecting the trigger rod. Since the parts are set for automatic fire, a stop device limits the trigger's movement back to the position shown in Fig. 10, in which position the trigger has come into contact with the trigger rod but has not yet displaced it.

Hammaren H Sr medelst en lageryta (ett faste) 71' (fig. 20) sviingbart lagrad I underbeslaget R' pa en tapp 72, varvid lagerhylsan Or fOrsedd med en frarnatriktad forlangning 73, som ingriper med en uppatriktad yta underbeslaget R' for att, da underbeslaget R' avtages fran mekanismladan R, begransa hammarens svangningsrorelse till nagot forbi avfyrningslaget.

Med omstallaren i detta lage vilar bakre klacken 95 av avtryckarstangens utlosare mot bottnen ay sparet 105 ungefar yid punkt 111 (fig. 6), sa att den byre anden 96 av utlosaren fortfarande Or ur banan for utlosningsbulten TP (fig. 9 och 24). Delen 108 lyfter manoverorganet CC for slutstyckets spiinnhavstang BC upp ur sparet 194, varvid denna svanges till overksaint lage, och varvid slutstycket, om det drages tillbaka i detta ogonblick, kan fOras till reglat lage, och det djupa urtaget 115 star mitt fiir avtryckarens bakre andyta 57, sa att avtryckaren kan foras till silt bakersta lage. Under forsta hfilften ay avtryckarens tillbakadragning tillslutes mellanrummet mellan avtryckarens overdel och avtryckarstangens underdel, och under den senare hfilften ay tillbakadragningen svanges avtryckarstangen S kring bulten 48, sa att hammaren frigives (fig. 24), varefter .slagfjadern HS svfinger hammaren till anslag mot slagstiftets FP bakre an- — — de. Nar slutstycket kastas bakat, for en yta 121 (fig. 9) hammaren tillbaka till ingrepp med avtryckarstangen. Om avtryckaren frigivits, griper hammaren haken 67, men om avtryckaren fortfarande Mlles i tillbakadraget lage, halles hammaren av haken 68 tills avtryckaren friges, varefter hammaren kopplas over till haken 67. Ndr slutstyckets spannhavstang BC Mlles i overksamt Idge, under det att delarna dro installda for patronvis eld, sâ framfores och reglas slutstycket efter varje skott, och avtryckaren maste anyandas for varje skott. For cartridge fire, turn the switch W until the handle 103 reaches the layer S 0 fig. 96 of the trigger is still Or out of the path of the release bolt TP (Figs. 9 and 24). The part 108 lifts the actuator CC for the spindle holding rod BC of the bolt out of the groove 194, whereby it is swung to the overcurrent position, and whereby the bolt, if retracted at this moment, can be moved to the regulated position, and the deep recess 115 is in the middle of the rear face of the trigger 57, said that the trigger can be moved to the silt rearmost layer. During the first hfilft ay the trigger retraction the space between the trigger part and the trigger rod lower part is closed, and during the later hfilften ay the retraction the trigger rod S swings around the bolt 48, so that the hammer is released (fig. 24), after which the striker HS FP hits the hammer bakre an- - - de. When the bolt is thrown back, a surface 121 (Fig. 9) brings the hammer back into engagement with the trigger rod. If the trigger is released, the hammer grips the hook 67, but if the trigger is still Mlles in the retracted position, the hammer is held by the hook 68 until the trigger is released, after which the hammer is switched over to the hook 67. for cartridge-by-fire fire, the bolt is advanced and adjusted after each shot, and the trigger must be different for each shot.

For automatisk eld ãr omstallarens W handtag 103 svdngt till det bakre med F fig. 1 betecknade lfiget. I detta lase ãr klacken 89 i ingrepp med urtaget 90, som befinner sig Overst a fig. 7, varvid den utstaende anden av bulten 113 hindrar ytterligare vridning av omstallaren i denna riktning. Enligt fig. 10, som visar delarna installda for automatisk eld, kan man8verorganet CC for slutstyckets spannhavstang fritt falla in i sparet 104, om avtryckaren fores tillbaka, varvid fjadern A kan fOra spfinnhaystangen BC till det ldge, i vilket den hailer slutstycket i tillbakadraget Idge. Det grunda urtaget 116 (fig. 5) befinner sig mitt f8r avtryckarens bakre kant 57, sa att avtryckaren endast kan f8ras sa langt tillbaka som erfordras for att tillsluta mellanrummet mellan avtryckarens overdel och avtryckarstangens underdel, men ej lfingre. Harigenom verkar ej avtryckaren direkt mot avtryckarstangen for att frigora den Iran hammaren. Emellertid Or detta korta tillbakaforande av avtryckaren tillräckligt for att medelst manoverorganet CC fora spannhavstangen BC ur ingrepp med slutstycket. Bakre klacken 95 pa avtryckarstangens utlosare ST vilar mot omstallaren W ungefar vid punkt 1(fig. 6), varvid bryggan 96 pa avtryckarstangens utlosare ST Mlles i utlosningsbultens TP bana. Da slutstycket uppnar sitt reglade lige for utlosningsbulten nedtryckes hdrigenom avtryckarstangens ST fran det heldragna ldget till det prickade laget (fig. 10), varvid avtryckarstangens S framande tryekes ned tillrackligt mot verkanfjadern 69 for att frige hammaren fran avtryckarstangen. Sa ldnge avtryckaren halles i detta halvt tillbakaforda ldge far att halla slutstyckets spann- hdvstang SC fri fran slutstycket, fortsatter slutstycket att ga fram och tillbaka fOr automatisk eldgivning. Ndr avtryekaren slutligen frigives, Rims spannhavstangen upp och fast-hailer slutstycket i tillbakadraget lage. For automatic fire, the switch 103's handle W is swung to the rear with the fig. In this lock, the lug 89 is engaged with the recess 90, which is located at the top of Fig. 7, the protruding spirit of the bolt 113 preventing further rotation of the switch in this direction. According to Fig. 10, which shows the parts set for automatic fire, the actuator CC for the bolt rod of the bolt can freely fall into the groove 104, if the trigger is moved back, whereby the spring A can move the pin rod BC to the length in which it holds the bolt in the recess Idge . The shallow recess 116 (Fig. 5) is located in the middle of the rear edge 57 of the trigger, so that the trigger can only be moved back as far as required to close the space between the upper part of the trigger and the lower part of the trigger rod, but not the finger. As a result, the trigger does not act directly on the trigger rod to release the Iranian hammer. However, this short return of the trigger is sufficient for the means of the actuator CC to disengage the span sea rod BC from engaging the bolt. The rear lug 95 on the trigger rod trigger ST rests against the switch W approximately at point 1 (Fig. 6), the bridge 96 on the trigger rod trigger ST Mlles in the TP path of the release bolt. When the bolt reaches its bolt straight in front of the release bolt, the trigger rod ST is thereby depressed from the solid edge to the dotted layer (Fig. 10), the front of the trigger rod S being pressed down sufficiently against the action spring 69 to release the hammer from the trigger rod. As long as the trigger is held in this semi-retractable position, keep the bolt SC clamp lever SC free from the bolt, the bolt continues to reciprocate for automatic firing. When the trigger is finally released, Rims the sea rod up and fastens the bolt in the retracted position.

Hdrigenom lamnas ej nagon patron i del heta patronldget efter sista skottet. Om avbrott eldgivningen intraffar pa grund av brist pa ammunition i magasinet i stallet for att avtryckaren friges, sd kommer slutstycket att stanna i sitt framre age. As a result, no cartridge is left in the hot cartridge compartment after the last shot. If the interruption of the firing occurs due to a lack of ammunition in the magazine in the stable for the trigger to be released, then the bolt will remain in its forward age.

Av det foreghende framgar tydligt, att slutstycket ej stannar i det frdmre, reglade ldget efter en period av automatisk eld, da en lad-dad patron eljest skulle kvarbliva i ett heft patronlfige, vilket fir farligt. From the foregoing it is clear that the bolt does not remain in the front, regulated after a period of automatic fire, when a loaded cartridge would otherwise remain in a heavy cartridge compartment, which is dangerous.
