Definitions
- the present invention relates to improvements in a firearm provided with one or more recoil-absorbers of the type described in the United States Patent No. 1,333,402, dated March 9, 1920.
- Each of said recoil absorbers is mounted at the end of the barrel of the fire-arm, coaxially therewith, and rejects the gases of combustion in a backward direction. It comprises a nozzle coaxial with the gun muzzle and arranged in'extension thereof, said nozzle being of divergent shape toward its outer end to afford an expansion chamber, an end closure for the nozzle having a central opening for the passage of the projectile therethrough, and a single annular gas escape passage, opening from the interior to the exterior of the nozzle, said passage being of increasing cross section toward its discharge end to accelerate the escape of gases therethrough.
- the gases resulting from the combustion of the propellant., deected by the recoil-absorber in a rearward direction, have retained a portion of their velocity, so that they constitute an inconvenience and even a danger for the personnel serving the firearm which is provided with the recoil absorber. .1
- My present invention consists in the combination, in a fire-arm provided with 'one or more recoil-absorbers of the aforesaid type, of means placed behind said recoil absorber or absorbers for collecting substantially the whole of the gases escaping therefrom and for substantially completing. the expansion of said gases, and of means for allowing said gases after substantially complete expansion to escape into the atmosphere in a direction non-injurious to the personnel.
- my invention consists in the combination in a fire-arm of a tube, forming a tubular collector and, if neces- 1, 1921. Serial No. 512,078.
- this tube When this tube is connected to an exhaust expansion chamber with or without a silencer device, it suppresses also the flash of the discharge and a great portion of the noise resulting from the direct escape of the gases to the free air.
- the recoil absorber according to the prior United States Patent No. 1,333,402 comprises a nozzle 'and a single reacter surface, of a shape affording a maximum transformation of the internal energy of the propellent gases into kinetic energy, and a maximum velocity and momentum of the gaseous streams at the moment lof their exit from the recoil-absorber, without shocks or eddies.
- Tests made with a military rifle of the Springfield or United States Army type, provided with a device according to this invention, have shown not only a reduction of the recoil by 60 per cent, but also a reduction of the blast by 100 per cent, of the flash by 100 per cent, and of the travel of the report by 75 per cent.
- Figs.y 1 and l8 arey longitudinal sections through'adjacent portions'o't the barrel of a fire-army providedy with my device;
- Figs. 3 yand 3a? are yviews similarfto Figs.
- notvotherwiseessential,y has for object tov ensure the rejection through the annular throat as of the vane-member, that is to say in a backward direction, of the greatest possible proportion of the' gases from the burnt charge, and to obstruct the flow of the very small portion which escapes through the central passage a4 in the vane-member.
- a metal tube o forming a silencer or expansion-chamber arranged around the barrel Z1 of the ril-le and parallel to the latter; this tube -collects the stream of gas which otherwise would tend to spread out into the atmosphere at the exit from the recoil-absorber, and conveys it in a cylindrical flow which is directed into the silencer or exhaust chamber c, like the exhaust gases of an explosion engine at leaving the manifold provided beyond the exhaust valves.
- the tube 0 damps or muumbles the gases rejected by the recoil-absorber, as a result of the expansion to which they are subjected in this tube.
- the latter surrounding the barrel b of the latter is closed at rear end as indicated at o2 and is supported by the barrel by means of a distance piece es; this tube may contain baffles of any suitable shape, for instance a truncated conical baille c* and the pallet-shaped baiie plate c5, the latter directing the gases, which have expanded around the tube c, towards the exyfterior through one or more ports c, It is,

- This silencer or exhaustcharnber may rbe yarranged'so.as'not to beA located for its wholelength around vthe vbarrel b; rsuch an arrangement is represented in the 'form of constructiony in Figure', which differs from the foregoing'only vby vthe fact that the tube c, connected to the recoil-absorber at 01, is at irst placed concentrically'of the barrel I), then swept' downwards yandy yar-y ranged below they barrel forthe remainder of its length, parallel to yther barrely or 'in'r any other manner.

- Figs. 3 and 3a represent anot er form of construction, in which the tube c forming the silencer is arranged concentrically around the barrel b of the tire-arm; this tube c is fitted at its front end at c1 upon the recoil-absorber a, a1 a2, and at its rear end at b1 upon the barrel; the tube c is pierced with a large number of small elliptical ports c7 arrangedin quincunx fashion, to allow the escape of the gases after their expansion in this tube, with a reduction of velocity and sound and without flash, in a direction where they cannot injure the personnel ofthe gun.
- a duplex-effect apparatus comprising two recoil-absorbers arranged in tandem.
- the tube c forming the silencer, and secured to the primary absorberby suitable profiled arms a, is screwed at its rear end at b1 upon the barrel b of the gun; the vanemember 11 of the secondary absorber a is screwed at'a11 upon the front end of this tube, see Figure 4.
- gases to expand immediately into the atmosphere in a stream with eddying or divergent currents so as then either to be merely diverted in a direction non-injurious for the personnel, for example by introducing a bend in the collector, before being rejected to the atmosphere, or alternatively and preferably to be passed into a silencer device which may be formed by the collector itself or by an apparatus like the expansion-chambers employed upon automobiles.
