Definitions
- This invention relates to machine guns and enable the breech body and the barrel in operaautomatic small arms and especially to machine tion to be locked together firmly but in a-quickly guns of the gas operated type and intended more releasable manner, the rearwardly projecting particularly for use in tanks.
- extremity ofzthe barrel entering a recess in the The-chief object of the invention is to evolve breech body; I I 5 a construction of'machine gun or automatic small In Figures 1, 2-and .3, the left hand barrel is arm in whichbarrel change is facilitated whereby shown in operation and with this arrangement a cool barrel may be quickly brought into operawhen it is desired to change .over from one barrel tion in substitution for one which has become to the other, theloc'king bolt "or nut is first rehot or otherwise temporarily or permanently leased, thus enablingthe breech body to be com- All rendered unfit for use, and in which the opera pletely removed from the rearwardly projecting tion of changing from one barrel to another can extremity 'of the one barrel and placed in posibe effected within a confined space as for example tion upon the extremity of the adjacent barrel,
- the barrels 9, two of which are single common breech mechanism, the breech preferably provided, are movable relatively to the body or barrels or both being relatively movable breech body l0, and also relatively to a common to enable any one of the barrels to be brought gas cylinder H, the barrels being partially rotat- 20 into operation at one time.
- Figure 3 is a plan view.
- the barrels have independent gas blocks l5,
- Figure 4 is a longitudinal vertical section illusheld together by means of an extension ll of the trating a modified construction.
- gas cylinder, and arranged so as to compensate Figure 5 is a transverse section on the line for the longitudinal expansion or contraction of 35 A--B in Figure 4. the individual barrels.
- Each barrel 9 has a port Figure 6 is a rear elevation of the mounting l6 communicating with the gas block port I8, shown in Figure 4, the breech mechanism having and which only aligns with the cylinder port I1,
- the breech body mounting I2 adjacent each terminal position, the 5 is so arranged that it can be moved out of catch I!) being carried by an arm or lever 21 register with the one barrel and into register with secured to the block l2 and by which the latter 50 the other barrel when it is necessary to change may be rotated, the barrels being rotatable over, the rearwardly projecting part 6 of each throughout an angle of 90 or as required.
- Each barrel having locking teeth or projections I for barrel 9 projects rearwardly of the block I2, the co-operating with corresponding parts of a lockrearwardly projecting extremities 22 of the baring nut or bolt 8 carried by the breech body to rels having teeth or projections 23 adapted to 55 engage corresponding teeth or projections in the breech body I!) when their associated barrel is in its operative position.
- the invention is particularly suitable for use in connection with guns which are intended for use in tanks or other confined spaces where the barrel itself is'not easily accessible and consequently could not easily be removed from the mounting and exchanged.
- a machine gun or automatic small arm of the gas operated type comprising a mounting, a plurality of barrels, a breech body and gas cylinder common to all of said barrels, said barrels being revolubly mounted within said mounting about the axis of said gas cylinder so as to bring any one of said barrels individually into register with said breech body and into communication with said gas cylinder, a gas block associated with each barrel and having a gas port communicating with its associated barrel and adapted to register with a further port in said gas cylinder when its associated barrel is in the firing position in which it' registers with the breech body.
- a machine gun or automatic small arm of the gas operated type comprising a mounting, a plurality of barrels, a breech body and gas cylinder common to all of said barrels, said barrels being revolubly mounted within said mounting about the axis of said gas cylinder so as to bring any one of said barrels individually into register with said breech body and into communication with said gas cylinder, a separate gas block associated with each barrel and having a port for connecting its associated barrel when in the firing position with said gas cylinder, the gas blocks of all the barrels being loosely connected together to allow of longitudinal expansion of the individual barrels.
- a machine gun or automatic small arm of the gas operated type comprising a mounting, a plurality of barrels, a breech body and gas cylinder common to all of said barrels, said barrels being revolubly mounted within said mounting about the axis of said gas cylinder so as to bring any one of said barrels individually into register.
