AUTOMATIC GUN'.
Application led October 27, 1926, Serial No. 144,559, and in France January 23, 1928.
The present invention relates to an automatic gun of the type of those which, during tiring, recoil in a cradle, the gun comprising, like other known automaticl guns, a mechanism for opening and closing the breech, a firing mechanism, a cartridge distributing mechanism, a mechanism for ramming the cartridges into the bore of the gun barrel and a device for ejecting spent cartridge cases, all these mechanisms and this device operating automatically by means of the energy taken from the recoil of the gun barrel in its cradle.
The new un has been designed in such a way as to e adaptedto work normally as an automatic gun, while for firing a first projectile it is possible without any great effort. to actuate, by sim le manipulation of a member such as a han le or a lever, all the mechanisms, which, for firing the subsequent projectiles, operate automatically.
The firearm has further been designed in such a way that it is possible, still by the simple manipulation of a member such as a lever or a handle, to carry out contmuous tiring or intermittent firing shot by shot, that is to say, at intervals varied as desired.
The construction of the firearm is finally designed not only with a view to obtaining the various functions enumerated above but in such a way that, with/a view to making it possible to increase the speed of firing the recoil will be as small as possible, and that the forces to which the mechanisms are subjected remain practically constant in spite of the variations in the speed of the gun barrel during the vrecoil and the re-entry into battery position.
The firearm comprises, like other known automatic guns, a cover or casing projecting to the rear upon the breech, but according to the invention this casing is made movable longitudinally, for example upon guides projecting upon the cradle by means of a mechanism actuated by a simple handle. relatively to the gun barrel at rest, While normally the said casing remains stationary while the gun barrel moves relatively to it by recoiling in its cradle and by re-entering into battery position.
In order thatv this mobility may be obtained by simple means, which, at the same time produce avery small recoil, the move \ments of the breech block and those of the cartridge distributor are, according to the invention, produced by guide cams upon or 1n which move rollers, these members (guides and rollers) being carried respectlvely, the ones by members movable with the gun barrel, the others by the movable casmg. As described hereinafter by means of t-he suitable profiles of the guldes the force developed upon the recoil for the operation of the corresponding mechanisms remains practically constant during the whole of this operation in spite o-f the va.- riations in the speed of recoil.
A practical form ofthe invention is illustrated by way of example in Figures 1 to 9 in the accompanying drawings.
Fig. 1 is a plan section along the axis of the gun barrel showing the whole of the back part of the firearm, that is to say, that part which comprises all the new characteristic devices of the invention.
Fig. 2 is a corresponding longitudinal sectional elevation. In these two first figures the members are shown in an intermediate position of operation a moment before the cartridge is rammed into the bore ofthe gun barrel.
Fig. 3'is a longitudinal elevation of a part of dtlQle firearm corresponding to Figs. 1 an Fig 4 is a sectional elevation of a part cel similai` to that shown in Fig. .2 and showing the firearm loaded, the breech closed, with the members in the firing position.
Fig. 5 is a similar longitudinal sectional elevation to that shown in Figs. 2 and 4 the members being shown in the position they occupy towards the end of the recoil, the breech being at this moment completely open and the spent cartridge case in process of ejection.
- Fig. 6 is a plan view seen from above with a part in section taken along the line 6-.6
in Fig. 7, which is a cross section along the line 7 *7 in Fig. 5.
Fig. 8 is a sectional elevation along the line 8 8 in Fig. 1.`
Fig. 9 is a back elevation of a part.
Figs. 10 to 35 illustrate a special form of' the invention. This form enables firing to be speeded up particularly on account of the fact that the spent cartridge case can be
