Definitions

  • the invention relates to a compressed air weapon especially an air gun.
  • Air guns have in general the advantage that their ammunition is much cheaper than the ammunition for small calibre firearms, for which reason air guns are preferred for use for training purposes.
  • the known air guns have, however, the disadvantage as compared with small calibre arms that the weapon is very tiring to fire since the air gun is 'released by means of a very stronglystressed spring which operates on a comparatively heavy air piston. The recoil of the weapon felt by the marksman is caused by the reaction force produced Iby the release of the spring.
  • the invention on the lother hand consists in the fact that at least the barrel and the breech of the compressed air weapon are displaceably supported in the stock.
  • the invention has primarily the great advantage that now compressed air weapons according to the invention remain just as-quiet or under some circumstances still quieter in the hands of the marksman, than small-bore weapons so that an air gun constructed according to.
  • the invention has both the advantage that the ammunition is comparatively cheap and also has the advantage previously only obtainable with small calibre weapons, namely that the weapon remains quiet in the hand on firing.
  • the trigger device can remain fixed in the stock and only the barrel and the breech block, the compression sleeve, the compression piston, the spring and the cocking device embodied therein are displaceably mounted in the stock.
  • the whole weapon system or action is displaceably mounted in the stock.
  • the displaceable mounting can moreover be constructed is the recoil.
  • the displaceable parts can be slidably supported so as to be completely free in the axial direction.
  • the marksman can slide the movable system of the weapon by hand towards the front up to a stop, before ring, so that the system moves to the rear when firing. Owing to the friction opposing the sliding movement of the displaceably supported parts, this completely free movability of the system does not appear to be objectionably apparent in handling the weapon.
  • a return spring may engage the displaceable parts, which brings the system after firing back again on its own to its forward end position.
  • the greater is the force of this return spring by which the system is pressed forwardly the greater is also the recoil which is transmitted by this spring to the stock of the weapon.
  • This embodiment of the invention can furthermore be so constructed that the aforesaid blade springs upon which the weapon system or action isdisplaceably supported, returns the weapon system or action to its forward end position.
  • a return spring can be constructed also as a coil spring and may engage any part of the displaceable system.
  • no return spring engages the displaceable parts, which spring brings the system back to its forward-end position after firing.
  • this return movement is derived from the parts movedon cocking the weapon.
  • the weapon is cocked, the system moves automaticallyin the forward direction. Since the return movement of the system is not opposed by any spring force, there is obtained in this Way a practically recoil-free air gun, the system of which returns automatically to the tiring position on cocking the weapon.
  • the feature of the invention of securing the return movement of the movable parts from the cocking movement of the firearm can be carried out in various ways and by various means.
  • a stop fixed to the stock may be present for example in the path of this cocking lever.
  • this compression sleeve is again moved forwardly, the part of the weapon system which co-operates with the stop fixed in the stock, is joinedto the compression sleeve.
  • a locking device which retains the displaceable parts in their forward end position and is unlocked on firing so that the displaceable parts can move back without hindrance on firing
  • This locking device can be formed by a pawl which drops behind a stop in the forward position of the displaceable parts.
  • This locking device can be associated with the trigger so that on pressing the trigger the locking element moves away from the stop.
  • FIG. l shows the supporting for the weapon system or action on blade springs
  • FIG. 2 shows the mounting of the displaceable parts of the weapon system on rollers in accordance with another embodiment of the invention
  • FIG. 3 shows a detail of FIG. 2 on a larger scale and in section on the line III-III in FIG. 2,
  • FIG. 4 shows an embodiment of the invention in which theA return spring is formed by a coil spring
  • FIG. 5 shows another embodiment of the invention
  • FIG. 6 shows a detail of this embodiment
  • FIGS. 7 and 8 show the relative positions of the displaceable parts during the cooking operation
  • FIGS. 9 and 10 show sections on the lines XI-XI and XII-XII in FIG. 5 respectively,
  • FIG. 11 shows an embodiment of the locking device after the displaeeable parts have been moved forwardly during the cocking movement
  • FIG. l2 shows another embodiment of this locking, both FIGS. 1l and 12 being shown on a larger scale.
  • the weapon system or action embodies a barrel 1 and a breech casing 2 in which a compression cylinder 3 is displaceably mounted, housing a compression piston 4 fastened to a rod 5 which embodies at its rear end a nose portion 6 by which it engages a stop of the trigger device, marked generally at 7, on cocking the weapon.
  • the piston 4 is under the influence of a compression spring 41.
  • the barrel 1, the breech casing 2 and the trigger device 7 are arranged in a common housing and form the weapon system or action.
  • This Weapon system is displaceably mounted in the stock and is anchored to the stock by means of two blade springs 8 and 9.
  • the spring 8 is fastened at its lower end by means of a screw 10 to the forward part 11 of the stock of the weapon. It extends for a substantial part of its length in a recess in the stock perpendicularly to the displacement direction of the weapon ⁇ system during recoil.
  • This section 12 running perpendicularly to the displacement direction is continued by a bent end portion 13 fastened to the action.
  • the rear part of the action engages the spring 9, the bent end 14 of which is likewise fastened by means of a screw 15 to the stock.
  • this spring embodies a section 16 extending vertically upwards in a recess in the stock, that is perpendicular to the displacement direction and which is followed by a bent end part 17 fastened to the action.
  • the trigger guard 18 can be fastened to the lower edge of the front stock 14 extending beneath the trigger, so that on firing the trigger 20 moves relatively to the guard 18. Also, the guard 18 can be rigidly connected to the action so that also the guard moves with it.
  • the blade springs 8 and 9 are so formed, preferably by suitable choice of their width, that they do not permit any lateral movement transversely to the sight axis, but only a swing in the longitudinal direction of the weapon that is in the direction of the sight axis.
  • the springs 8 and 9 serve both as a support for the weapon system and also as return springs for the action after ring.
  • FIGS. 2 and 3 differs from the embodiment according to FIG. 1 by the fact that the action is not supported on blade springs but on slide and roller bearings.
  • One roller bearing 21 is located adjacent the rear end of the barrel.
  • support rollers 22 are rotatably supported on bearing pins 23 in the action.
  • the rollers 22 rest on inclined surfaces 24 provided on a bearing member 25, the precise position of which can be adjusted by means of a screw 26 which is rmly anchored in the stock, as is the bearing member 25.
  • Rollers 29 are also rotatably mounted on bearing pins 2S supported in lugs 27 of the action. These rollers 29 are arranged at a distance one from the other in the longitudinal direction of the weapon.
  • a presser pad 30 rests on the rollers 29 and embodies bearing surfaces 31 in the region of the rollers 29.
  • the presser pad 30 embodies recesses 32 in which a blade spring 33 is inserted, which is anchored by a screw 34 in the front stock part 35. The spring force exerted on the presser pad by the rollers 29 can be adjusted by means of the screw 34 and thus the action is held downwardly against the stock.
  • a further bearing 36 which can be constructed as a simple slide bearing or also as a roller bearing.
  • a coil spring 37 serves as a return spring for return of the action to control position, this spring resting on a plate 38 -which forms the one end face of a hollow space 39 receiving the spring.
  • a plate 40 closing this hollow space 39 on the other side is connected rigidly with the plate 38 by means of side walls fastened in the front stock 35.
  • the hollow space 39 is open above and beneath and a pin 41 passes through it which is fastened to the barrel 1 by means of a screw 42.
  • a support member 43 is fastened to this pin 41 within the hollow space 39 and embodies a shoulder 44 which engages the movable end of the return spring 37 and projects on both sides beyond the pin 41 and carries buffers 45 and 46 of resilient material at its ends, which limit the displacement movement of the action by acting as stops against the plates 38 and 40.
  • FIG. 4 differs from that of FIG. 2 only by the fact that the return spring is arranged at a different position and the associated parts are of simpler construction.
  • the return spring 48 rests on the end face 49 of a recess 50 and presses on a plate 51 fastened to the action.
  • a spring guide body 52 is located in the hollow space 50.
  • the part 43 forms the spring guide body.
  • a breech housing 53 together with a barrel 54 and all the parts associated with the breech housing are displaceably mounted in a stock 55.
  • Pins S6 fastened to the breech casing adjacent to the bolt support, are used as the suplever.
  • a compression cylinder 63 is axially displaceable in the breech housing 53 and a compression piston 64 is displaceably movable therein and is under the action of a spring 65 bearing against a ring shoulder 66 of the breech housing 53.
  • a piston rod 67 pertaining to the compression piston 64 there is provided a nose member 63 which, with the weapon cocked, engages over an inclined surface 69, inclined somewhat relatively to the radial plane of the rod 67, on a nose portion 70 of a catch 71 as shown in detail in FIG. 1l.
  • the catch is locked by the trigger by means of an intermediate element not shown.
  • this spring 7S engages a recess in the web portion 76 of the U-shaped member 76 and the other end of the spring 78 is fastened in a holder 71 adjacent the nose portion 70.
  • This spring tends to rock the U-shaped member 76 in the ⁇ counterclockwise direction and to hold the lower edge of the web 76 in the recess of the pin 61 defining the stop face 77 thereof.
  • the end 74" of the lever 74 is so arranged ⁇ that when the weapon is cocked, that is when the rear end of the piston rod 67 is in the position shown in FIG. 9 on rocking the catch 71, it comes into engagement with the rear end of the piston rod 67. If the catch 71 rotates further in the clockwise direction around the pin 72 the end part 74 lifts the web 76 of lthe U-shaped member 76 over the end face 77 so that the whole action can slide rearwardly on the pins 56 and 61 to reduce the recoil.
  • a cocking lever 80 is pivotally mounted as shown in FIG. 6 on the breech housing 53 on a pin 79.
  • a tension rod 82 the forward end of which is fastened to the compression cylinder 63 is pivoted at 81 to the cocking
  • a slider member S3 is also fastened .to the compression cylinder 63. If the cocking lever 80 is moved outwardly for cocking the gun around the tensioning pin 79 the compression cylinder 63 together with the com pression piston ⁇ 64 and the slider 83 are moved to the rear. portion 68 of the piston rod 67 catches against the nose part 70 of the catch 71.
  • the cocking lever is again moved back to the position shown in FIG. 6 after cocking the weapon.
  • the compression cylinder 63 together with the slider 83 are again moved forwardly so that the slider member S3 is no longer resting against the stop 84 and thus on ring the action can slide rearwardly without hindering the reduction in the recoil.
  • the action can be moved back after firing without moving the cocking lever 8) tothe firing position.
  • the breech casing 53 need be moved forwardly until the U-shaped member 76, 76 enters behind the end face 77.
  • the last described embodiment of the invention has the considerable advantage that the displaceable parts always have the same starting position on firing and thereby have the same working positions and that the weapon can be handled like a weapon with a rigid action. Furthermore, the locking movement can also be coupled with another movement, for example the forward movement of the system.
  • the aforesaid locking action in the various embodiments of the invention can be effected independently of the manner in which the displaceable parts are moved forwardly to their starting position, whether by hand, by a spring or, as in the constructional embodiments shown, simultaneously with the cocking action by the cocking lever. It is only essential that the locking action shall be released during firing.
  • the unlocking movement can, as already stated, be obtained directly from the movement of the trigger, but in other embodiments of the invention it may only be operatively connected with the trigger insofar as on depressing the trigger, forces are released which besides other functions, serve to initiate the unlocking movement.
  • the displaceable parts may be locked in their forward position independently of the cocking condition and independently of the trigger in its forward position, which gives certain advantages in the handling of the weapon.
  • FIG, 12 differs from the embodiment of FIG. l1 by the fact that the two-armed lever 74 and the U-shaped member 76 are replaced by a locking element 76 which is 'pivotally mounted on the shaft 72.
  • a coil spring 78 which is suspended beneath the pivot of the locking element 76 rotates said element in the counter-clockwise direction and thus causesit to bear on the surface of the xed pin 61.
