Description

Uppfinnare: H Burni Prioritet begtird frdn den 30 september 1957 (Schweiz) Det är vid projektiltandare med tandstift kant att i en forsdnkning i spetsen anordna en smaltkropp, vars frdmre yta dr utsatt for luftstr8mmen, och som, intill dess att den =alter, sakrar tandstiftet mot forskjutning. Inventor: H Burni Priority started on 30 September 1957 (Switzerland) In the case of projectile teeth with toothpicks, it is to arrange in a recess in the tip a narrow body, the front surface of which is exposed to the air flow, and which, until it = alter, secures toothpick against displacement.

Det har visat sig, att smaltkroppen, som hestar av en legering av tvd., tre eller fyra av elementen Sn, Bi, Pb och Cd eller av legeringar av elementen Sn och Ti eller Bi och Ti eller Sn och In eller av legeringar av tre av elementen Sn, Pb och Zn eller Sn, Cd och Ti, icke har den far ammunition erforderliga lagringsbestandigheten av flora dr. Smdltkroppens avsedda funktion blir osdker redan efter kort lid. De oskyddade smaltkropparna korrodera ndmligen mycket snabbt och kraftigt, och till foljd av de fordndrade ytfOrhallandena komma tandarens osakringsfunktioner att utlosas oregelmassigt i fraga om tiden, sh att de fordrade sakerhetsdistanserna komma att i hog grad under- eller overskridas. It has been found that the narrow body, as horses of an alloy of tvd., Three or four of the elements Sn, Bi, Pb and Cd or of alloys of the elements Sn and Ti or Bi and Ti or Sn and In or of alloys of three of the elements Sn, Pb and Zn or Sn, Cd and Ti, the father ammunition does not have the required storage stability of flora dr. The intended function of the smelting body becomes obscure even after a short time. The unprotected fuselages corrode very quickly and strongly, and as a result of the required surface conditions, the tooth's unsecuring functions will be triggered irregularly over time, so that the required safety distances will be greatly under- or exceeded.

Uppfinningen bur till andamal att i fraga om lagringsbestandigheten forbattra proj ektiltdndare av ovan angivet slag. Enligt uppfinningen ernhs detta ddrigenom, att smaltkropparnas yta Or 8verdragen med .ett guldskikt. Genom denna ytbehandling hindras smaltkropparnas korrodering, sd. att smaltkroppens yta Oven vid en langvarig lagring av tandaren forblir oforandrad i alla avseenden. Harigenom hMla sig betingelserna fOr varmeovergangen frau luften till smdltkroppen ofOrAndrade under lagringstiden, och osakringsfunktionerna utlosas med stor regelbundenhet i fraga em tiden. The object of the invention is to improve project lighters of the above-mentioned type in terms of storage durability. According to the invention, this is achieved in that the surface of the molten bodies is coated with a gold layer. This surface treatment prevents the corrosion of the narrow bodies, sd. that the surface of the narrow body Even with a long-term storage of the tooth remains unchanged in all respects. As a result, the conditions for the heat transfer from the air to the molten body remain unchanged during the storage period, and the unsecuring functions are triggered with great regularity over time.

Vid kadmiumhaltiga smaltkroppar fOrhindras genom ett mellan smaltkroppen och guldskiktet anbragt silverskikt att omedelbart under guldbelaggningen krist Iler bildas, som vid tillvaxt bryta igenom guldskiktet och astadkomma en forandring av ytan. Det bur faststdllts, att det vid dessa kristallnybildningar Or fragan ern en ph diffusionsfenomen beroende, redan vid rumstemperatur upptradande reaktion mellan guldskiktet och smdltkropp ens legerings element. In the case of cadmium-containing molten bodies, a silver layer arranged between the molten body and the gold layer prevents the formation of crystals immediately during the gold plating, which during growth break through the gold layer and bring about a change in the surface. It should be noted that in the case of these crystalline new formations, or in question, a diffusion phenomenon is dependent, even at room temperature, on the reaction between the gold layer and the molten body's alloying elements.

En utforingsform av uppfinningen beskrives i det foljande med hanvisning till bifogade ritning, dar fig. 1 Or en langdgenomskarning av en anslagstandare i sdkrat laze, under det att fig. 2 och 3 visa tvd. olika utf5ringsformer av smaltkroppen I skarning. An embodiment of the invention is described in the following with reference to the accompanying drawing, in which Fig. 1 is a longitudinal section of a stop post in so-called laze, while Figs. 2 and 3 show tvd. different embodiments of the narrow body in cutting.

Tandarehuset 1 paskruvas projektilkroppen och Or vid sin framre ande tillslutet av en platta 15. I en urtagning i denna befinner sig en vid rag temperatur, exempelvis under 150° C, smaltande smaltkropp 16. Sasom framgar av fig. 2, Or smaltkroppen overdragen med ett guldskikt 116. Till ett i tandarens langdaxel sig strackande tandstift 2 Oro kopplade ,amar 3 med centrifugalvikter. 4. Tandstiftet 2 star under inverkan av en fj Oder 6. Denna stOder 0 ena sidan mot en ansats i tandarehuset och 0 andra sidan Over en hylsa 7 mot en krage 2a ph. thndstiftet och stravar att fora detta i riktning bakat Tandstiftets rorelse bakat hindras i (let i fig. 1 visade transportldget av den sfariskt for-made kropen 8, som Or beldgen i ett av delarna 9 och bildat, kulformat lager. Thudstiftets 2 framre dude skjuter i det i fig. 1 visade transportlaget genom ett hal 15a i locket 15 och kan av centrifugalkropparna 4 lake fOras i riktning framat, sh lange kroppen 16 Or osmalt. Den sfariska kroppen 8 är fOrsedd med tvenne cylindriska lagertappar 11, som Oro koaxiella med en mot thndarens langdaxe]: virikelrat axel och styrda i en slits 9a i 2— — delen 9. Den sfariska kroppen 8 fir salunda endast vridbar kring den av tapparna representerade axeln. Den initialladdningen innehallande sprdngkapseln 12 fir anordnad i en halighet i kroppen 8. I transportlaget ar kroppen 8 vriden sã, att tandstiftet 2 joke kan tranga in i sprangkapseln 12. I detta lage star tandstiftet 2 under tryck fran fjfidern 6 och vilar med en ansats 2b mot en plan yta 8a av kroppen samt forhindrar harigenom dennas vridning Den sfariska kroppen 8 fir lagrad med ett visst spel, sá att den kan utf8ra en kort r8- relse i riktning av tandareaxeln. Slitsens 9a langd är sa avpassad, att kroppen i sitt bakre lage anligger med sin hela yta mot lagerytan, och lagertapparna 11 hava ett visst spelrum i slitsen 9a. I kroppens 8 framre lage anligga lagertapparna 11 mot delens 10 underkant, under det att overytan av kroppen 8 joke är i berOring med det kulformiga lagrets yta. Tandaren enligt uppfinningen verkar pa foljande satt : I transportlaget är den sfariska kroppen 8 vriden pa sa satt, att tandstiftet 2 icke kan tranga in 1 sprangkapseln 12, och samtidigt .forbindelseoppningen mellan sprangkapseln 12 och forstarkningsladdningen 14 sparrad. Denna avsparrning astadkommer, att i fall av sjalvantandning av sprangkapselns 12 initialsprangamne under lagringen eller transporten forstarkningsladdningen 14 icke bring-as att detonera. Kroppen 8 kommer att av det med sin ansats 2b under fjadertryck mot den flata ytan 8a anliggande tandstiftet 2 hallas transportlage. The projectile body 1 is fitted with the projectile body and Or is closed at its front end by a plate 15. In a recess therein is a melting narrow body 16 at a low temperature, for example below 150 ° C. As can be seen from Fig. 2, gold layer 116. To a toothpick extending in the longitudinal axis of the tooth 2 Couplings connected, amar 3 with centrifugal weights. 4. The toothpick 2 stands under the influence of a spring 6. This stands 0 one side against a shoulder in the tooth housing and 0 the other side Over a sleeve 7 against a collar 2a ph. the toothpick and straws to guide it in the direction of baking The movement of the toothpick baked in is hindered in (shown in Fig. 1 the transport dough of the spherically shaped body 8, which is formed in one of the parts 9 and formed a spherical layer. in the transport layer shown in Fig. 1 through a hollow 15a in the lid 15 and can be carried by the centrifugal bodies 4 lake in the forward direction, sh long body 16 Or unsmalt.The spherical body 8 is provided with two cylindrical bearing pins 11, which towards the tooth's longitudinal axis]: rotated shaft and guided in a slot 9a in the 2nd part 9. The spherical body 8 is thus only rotatable about the axis represented by the pins. the transport layer, the body 8 is rotated so that the toothpick 2 joke can penetrate into the spring capsule 12. In this position the toothpick 2 is under pressure from the spring guide 6 and rests with a shoulder 2b against a flat surface 8a of the crown. The spherical body 8 is mounted with a certain clearance, so that it can perform a short movement in the direction of the tooth shaft. The length of the slot 9a is so adapted that the body in its rear bearing abuts with its entire surface against the bearing surface, and the bearing pins 11 have a certain clearance in the slot 9a. In the front layer of the body 8, the bearing pins 11 abut against the lower edge of the part 10, while the upper surface of the body 8 jokes is in contact with the surface of the spherical bearing. The tooth according to the invention operates in the following way: In the transport layer, the spherical body 8 is rotated in such a way that the toothed pin 2 cannot penetrate into the spring capsule 12, and at the same time the connection opening between the spring capsule 12 and the reinforcing charge 14 is locked. This cut-off ensures that in the event of self-ignition of the initial burst substance of the jump capsule 12 during storage or transport, the reinforcing charge 14 is not caused to detonate. The body 8 will be held by the toothed pin 2 with its shoulder 2b under spring pressure against the flat surface 8a.

Vid projektilens avskjutande komma -Land-stiff et 2 och den sfariska kroppen 8 till foljd av projektilens acceleration att tryckas bakat. Harigenom pressas tandstiftet kraftigt mot kroppens 8 flata yta 8a. Dartill kommer den till fOljd av accelerationen mot det kulformade lagret hart anpressade kroppens 8 friktion att motverka kroppens vridning. Forst sedan projektilen Iamnat vapenpipan, komma centrifugalkropparna att med en komponent av centrifugalkraften draga tandstiftet framat och darigenom astadkomma ett frigivande av den sfariska kroppen. Tandstiftet 2 lagger sig emellertid med sin framre ande an mot smaltkroppen 16 och hindras av denna i sin rorelse framat. Efter en viss tidrymd smatter emellertid smaltkroppen 16 till foljd av luf tens friktion mot densamma. Tandstiftet är nu oforhindrat att rora sig framat och intaga sitt osakringslage, varigenom den sfariska kroppen 8 frigives. Denna vrider sig dâ under inverkan av centrifugalkraften kring tapparnas 11 axel. I detta lage Mlles kroppen 8 av kulan 13, som ãr anbragt i urtagningen 8b och vid kroppens 8 vridning fares in i delens 9 urtagning 9b och kommer till anliggning mot delens 10 nedre kant. I delta lage kan tandstiftet tranga in i sprangkapseln, vars detonation genom. fOrstarkningsladdningen 14 8verfores till projektilens sprangamne. At the projectile's launch, -Land-stiff et 2 and the spherical body 8 result from the projectile's acceleration being pushed backwards. As a result, the toothpick is strongly pressed against the flat surface 8a of the body 8. In addition, due to the acceleration against the ball-shaped bearing hard pressed, the friction of the body 8 will counteract the rotation of the body. Only after the projectile has received the barrel will the centrifugal bodies, with a component of the centrifugal force, pull the toothpick forward and thereby bring about a release of the spherical body. However, the toothpick 2 abuts with its front spirit against the narrow body 16 and is obstructed by it in its forward movement. After a certain period of time, however, the fuselage 16 slams against it as a result of the friction of the air. The toothpick is now unobstructed to move forward and assume its insecure layer, thereby releasing the spherical body 8. This then rotates under the influence of the centrifugal force about the axis of the pins 11. In this position the body 8 of the ball 13, which is arranged in the recess 8b and when the body 8 rotates, is inserted into the recess 9b of the part 9 and comes into abutment against the lower edge of the part 10. In the delta layer, the toothpick can penetrate into the detonator, whose detonation through. The reinforcement charge 14 8 is transferred to the projectile's explosive.

Genom luftfriktionen avtager projektilens rotationshastighet kontinuerligt. Harigenom blir aven centrifugalkropparnas centrifugalkraft svagare, tills slutligen det ogonblick intraffar, da centrifugalkraftens axialkomponent blir mindre an fjaderns 6 kraft, varvid centrifugalkropparna 4 glida av ytorna 10a och tandstiftet av fjAdern 6 drives in i sprangkapseln 12 och astadkommer granatens detonation. Traffar projektilen ett mal, hopstukas tandernas framre del, sa att tandstiftet 2 drives in i sprangkapseln 12. Due to the air friction, the rotational speed of the projectile decreases continuously. As a result, the centrifugal force of the centrifugal bodies also becomes weaker, until finally the moment occurs, when the axial component of the centrifugal force becomes smaller than the force of the spring 6, the centrifugal bodies 4 sliding off the surfaces 10a and the tooth pin of the spring 6 being driven into the spring capsule 12. If the projectile hits a target, the front part of the teeth is crushed, so that the toothpick 2 is driven into the spring capsule 12.

Enligt fig. 3 är mellan den av en kadmiumlegering bestaende smaltkroppen 16 och guldskiktet 116 anbragt ett silverskikt 117. According to Fig. 3, a silver layer 117 is arranged between the narrow body 16 consisting of a cadmium alloy and the gold layer 116.
