Definitions

  • a machine gun of the Vickers type irl winch the firing om is operated during the locking action of 'a .side lever actuating a reciprocating A.breech block, is' characterised in that .the rir'ie Din displaceable to the n'rng' position in 'and relatively to the breech block, andthe side lever drives the nring .pin forwardly relatively to the breech blocl; to Yre the gun upon closing 'the breech.
  • a Side lever -pvoted to the breech block accommodating the firing pin and extractor, the -rng pin and the Seid lever having 12o-operating opposed 'parts adapted V:to be abutted together when the lever is moved into the locked nositionlthe arrangement being that the forward movement and the ring of the cartridges is controlled by thecontact between the side lever and the firing pinkwhen bringing the firing mechanism tothelocked position.
  • Figure 1 is a broken sectional side elevation of a Vickers machine gun breech mechanism in the firing position and embodying the present invention
  • Figure 2 is a sectional side elevation showing the breech mechanism with the breech block a full recoil and with a round positioned ready for ramming into the breech,
  • Figure 4 4 is a ⁇ sectional elevation showing the cartridge case of the 'last round being ejected'.
  • the'breech 13100K is in the form of a housing I .for the ring pin 5 and is .formed .at its rear fend with a .pendant abutment 2 adapted to ⁇ trip over a spring loaded scar-3 which normally prevents forward transla- :tivemovem'ent ofthe housing I and thecartridge C2 which is hield by its rim ⁇ in Yknown manner between the flanges IIa, of la, 'guide I1 upstarrd.-
  • posi- Vtive displacement, or forward pushing of 'the firing' pin-relatively to the housing I is obtained by the provision on the rear part of the ring pin of an abutment surface II located at a suitable angle, e. g. 45 to the axis of the ring pin, and a corresponding surface I2 formed on the side lever approximately midway between its ends,
  • the front end of the side lever being part of a known toggle action device and being pivoted to a pin I3 passed transversely through the front part of the housing I, the firing pin being slotted longitudinallyl as ⁇ at I4 to accommodate such transverse pin and to afford the requisite clearance for the reciprocation of the firing pin within the housing.
  • the firing pin is forced forwardly to re the cartridge by a face I2 on the side lever striking the face II on the firing pin at the instant the toggle action on the side lever closes and the mechanism is locked.
  • the cartridges are transported from the feed lbox I8, which is disposed immediately above the breech, to the barrel by the guide I'I which relceives the rim of the appropriate round as aforesaid, and the round is urged along the anges I'Ia simultaneously by the downward movement of the carrier I5 in channels I6 in the guide I'I, thus ultimately bringing the appropriate cartridge into engagement with the aforesaid spring Vloaded detent 3 (see Figure 2) in order that the cartridge may be located correctly at the front 'end of the housing and supported in co-axial -alingment with the barrel.
  • the reciprocating :imovement of the carrier vertically relatively to the axis of travel of the housing is controlled by I'an island type cam, i. e.
  • g Assembled to the said carrier I5 is a spring i loaded ejector 23 pivoted on a pin 24 to a slide ⁇ 25 slidably supported by the carrier for slight vertical reciprocation relatively to the carrier I5, this ejector operating to eject the case of the last cartridge from the lower end of the flanges -YI'Ia, the flanges in effect forming a T-section slot in the guide I'I to receive the cartridge case rims.
  • This ejector is defiected as shown in Figure tI L bythe cartridge C1 in the feed box, and is .thereby caused to be inoperative until there is Ino cartridge in the belt, when as shown in Fig- ;ure 3, the ejector is urged slightly forward by v ⁇ its spring 26 and with the slide 25 is carried down with the carrier to its lowermost position as shown in Figure 4 to eject the cartridge case C2 of the last fired cartridge over and beyond the aforesaid spring loaded detent 3.
  • the front edge of the slide is formed with a recess 21 dimensioned to receive readily the ejector 23, the ejector comprising a finger pivoted to the slide and spring loaded forwardly as aforesaid by the coiled compression spring '26, the arrangement being such that the lower part of this ejector is prevented from moving forwardly under the influence of such spring by reason of its engagement with the base of the appropriate cartridge C1 in the feed box, but following the removal of the last round in the feed box the ejector 23 is free to move forwardly on its pivot so that its lower end bears against the uppermost point of the base of the cartridge case and pushes such case downwardly beyond the spring loaded detent.
  • the ejector 23 is prevented from being pressed forwardly by its spring 26 when the cartridge C is positioned (as in Figure 2) in the loading position, by the lower edge of this ejector abutting against a step 28 on the front end of the breech block, thus causing the extractor to be pushed upwards relatively to the carrier so that the lower part of the extractor lies behind the corner piece I 5a of the carrier.
  • the extractor is formed with a recess or step 23a adapted to slip over the corner piece IEa when the extractor comes opposite vthe empty feed box I8 (see Figure 3) so that it cannot now be moved upwardly relatively to the slide 25 and forms a positive abutment to engage and eject the last cartridge case as in Figure 4.
  • a side lever In a machine vgun of the Vickers type a side lever, a reciprocating breech block actuated by said side lever, a firing pin displaceable in and relatively to the breech block, and co-operating opposed abutment surfaces on the side lever and ring pin which abut together when the side lever is moved into a position to lock the breech, said ring pin being urged forwardly by reason of said engagement of the abutting surfaces at the completion of the locking movement ofthe side lever to fire the gun.
