REMINGTON ASMS COMPANY, INO.

939 Baraum Avenue,

Bridgeport , Connecticut / V.St.A. Patent registration Lockable cartridge

The invention relates to Sehrotpatronen for firearms "■ and in particular verschiessbare shotgun cartridge body, which are intended to be driven out of the mouth of the firearm together with the shot charge or with another floor by the action of. Explosion gases generated by the deflagrating propellant charge.

In recent years considerable efforts and costs - especially in the military interest - have been made for the development of so-called caseless ammunition had been expended in order to make the usual cartridges with casings Replace brass or another metal. In addition to the saving in weight and volume, there is one caseless ammunition for the military of interests because it does not require any metallic casings that have to be collected in the field for reuse, especially when it comes to larger artillery barrel casings Caseless ammunition is also cheaper and can

"may have operational advantages. For example, since the entire cartridge is expelled from the rifle, the rifle system compared to the usual rifles are simplified, which carefully designed parts for pulling out and ejecting of the cartridge cases. Purely for the present consideration, combustible sleeves, in which the housing is made flammable material, fall under the term caseless ammunition.

The present invention takes a different approach which avoids various problems encountered with caseless Ammunition, but still allows you to enjoy almost all the advantages of caseless ammunition.

Caseless ammunition has not yet found widespread acceptance because of certain IT disadvantages which have not yet been eliminated could become. Caseless cartridges are not waterproof. They do not have a fixed structure and are receptive for premature or undesired ignition, e.g. B. from cigarettes, and tend to scorch in a hot rifle chamber (especially with automatic rifles) and the like. Solid propellant charges break easily when touched or loaded, especially with automatic or self-loading firearms. At present, compliance with the dimensions of the propellant charge is difficult and expensive to achieve and has to be achieved Grinding or turning can be achieved.

The current speeds, which are used with normal ammunition, d. H. When those with metal sleeves, allowed, were limited by the pressure, which is certain of the existing ones Firearms and ammunition cases can be withstood. at a caseless or lockable cartridge is the pressure and consequently also the speed not by that Strength of the usual sleeve is limited. It has long been known that firearms can be designed and executed who can withstand a much higher pressure than he can

0098 10/049

is currently used and limited by the usual brass tips. The restricting factor is then the gas seal, which must replace the sealing effect that is now exerted by the metal sleeves.

The present invention provides a closable shotgun cartridge or a cartridge body made of plastic, the from the muzzle of the firearm together with the shot or Another projectile is expelled, with no case or at least no essential parts of a case in the Rifle Chamber stay behind. The plastic cartridge body protects the propellant charge during storage and handling against moisture and unintentional ignition and gives the structure strength. A lockable cartridge from one of these Body is only slightly heavier than an equivalent caseless ammunition, but it avoids or is reduced in size on the other hand, the problems mentioned above.

In particular, the present invention provides a lockable cartridge which is expelled from the barrel of a rifle which has inwardly directed projections against which the cartridge strikes when firing. It includes the sealable cartridge has a tubular body thermoplastic material, which has a first chamber for receiving the propellant and ignition means and a second chamber at the opposite end of the cartridge body for receiving the projectiles, whereby each chamber is sealed from one another by a Transverse wall are separated. Furthermore, shoulder-like parts are provided, which extend outward from the outer Surface of the cartridge body extend out and store and support the cartridge in the rifle before firing, which however also allow the cartridge to disengage from the rifle upon firing so that substantially all of the cartridge is fired the gun barrel is driven out, or that at least part of the cartridge through the mentioned inwardly directed Projections in the gun barrel is broken off so that the projectile

The Pig. 1 shows an embodiment of the shootable body 10 for a cartridge 12 which is in an associated rifle • is housed prior to firing. Although the drawing shows the invention in a shotgun cartridge, it is intended to be the same They can be used with other conventional projectiles, such as rifle bullets and projectiles for industrial purposes etc. For the sake of consistency, the following description refers to a round with a shotgun charge.

per body 10, just like the corresponding body of the Modified embodiments described later, be produced by injection molding or by cold forming or according to Another common method of making plastic articles. Although any variety of olefin polymers or copolymers can generally be used, polyethylene is Either suitable for the production of the body. Other suitable long-lasting masses are ABS and ABS alloys (triple polymers j

009110/0495

from acrylonitrile, butadiene and styrene) "flexible vinyls, polyamides, cellulose, polycarbonates and others with suitable impact resistance.

The body 10 mm includes a tubular part 16 and an unperforated part Transverse wall or a web 18 which divides the tubular part 16 into two tubular wall parts 20 and 22 (Fig. 2). The transverse wall forms together with the tubular wall parts 20 and 22 a front open end cavity or chamber 24 for the shot and a rear open end Cavity or such a chamber 26 for the propellant. The wall 18 must be largely impervious to ensure that the full pressure of the explosion gases, which arises in the propellant chamber after the ignition of the propellant 28, is so directed, that it drives the body 10 through the gun barrel 30. The explosion gases must not enter the projectile chamber 24, where they would melt the pellets or affect their trajectory. The transition from the wall 18 to the tubular Part 22 is provided with a curvature in order to avoid a tension jump, which could result in the wall would be pushed out or sheared off when fired.

The propellant charge 28 for the present invention can either be a cast or pressed one-piece solid propellant charge or a loose or granular propellant charge, also liquid or gel-like. Figures 1 and 2 show the use of an integrally formed solid propellant charge 28 in which a cutout is formed into which a primer cap 34 is inserted and held in place by any known means. The primer cap 34 also has a cutout in which a primer 36 (in loose or pressed form) is housed. The primer cap 34 is made of a solid propellant charge which may or may not consist of the same propellant as the main charge 28, depending on the ballistic effect desired. The main propellant 28 is fixed in the propellant chamber 26 by an interference fit, adhesive, or other conventional means

009810/0495

Funds held. The primer cap 34 and primer 36 can be similarly used in the main propellant charge be attached. Of course, the primer cap can be omitted and the primer directly in one of the Main charge-shaped pocket inserted (Pig. 7).

The primer 36 is covered with a paper foil or other suitable means and that of the propellant and detonator The unit formed is sealed by a thin film 38 of suitable plastic material, either by a Adhesive is connected to the body 10 or is heat-sealed with it. Optionally, a coating paste, ζ. Β. Epoxy, can be used to seal the detonator-propellant unit.

A rim or shoulder 40 is on the outer surface of the body 10 is provided to form a surface for bearing and supporting the body against the striker. Enough Braking action is provided to hold back the cartridge for the effective ignition and combustion of the propellant charge However, the braking effect is low enough that the shoulder 40 comes loose before the peak pressure is reached, and the whole Cartridge is driven out of the muzzle.

Although the drawings indicate various ways of enclosing the shotguns 42 in the shot chamber 24, FIGS 1 and 2 show the use of a shot cover 44 'which serves both as a shot container and as a closure for the cartridge. The shot cover 44 is primarily made of plastic material and has a tubular side wall 46, which is open at its rear end and closed by a transverse end wall 48 at its front end. Slots 50 are provided across the end wall 48 and extend down the tubular side wall to a point in FIG Extending near the open end, but remaining a predetermined distance therefrom, around an unslit portion 52 to form, which serves as a hinge, as will be explained later. A

00 9810/04 9 5

small unslotted part (not shown) can also be in the Center of the front wall 48 can be provided to connect the various sections on the front side together, whereby the shot "is held until it is fired. The shot cover 44 is slidably mounted in shot chamber 24 and is retained therein by any known means, see B. by press fit, as in the Pig. 1 and 2 is the pail.

The preceding statements related to the embodiment after the pig. 1 and 2. However, various modifications of this cartridge design can be made within the scope of the invention to be hit.

"Pig. 3 shows a resealable cartridge similar to that after the pig. 2 with some changes. One change is that the load-bearing edge or shoulder 40a extends further extends forward than the shoulder 40 after the pig. 2.

Other differences of the pig. 3 compared to FIG. 2 consist in that the primer 36 is inserted into a disk 54 made of spherical powder and fastened there, which holds loose propellant powder 56 or such in pellet form in the propellant chamber 26. A groove 58 is attached to the rear end of the body 10 and runs inside the propulsion chamber, so that a shoulder 54 ^a that works with it can snap into a holding position on the disc 54

The Pig. 4 shows a solidly formed propellant charge 28a housed in the propellant chamber and a primer 36 which ι sits in a section of the solid propellant charge. This Pigur j also shows a groove 60 formed at the front end of the tubular j side wall 46 lies and with a corresponding locking shoulder 62 at the front end of the shot cover 44 sus &mmenar-; works to hold the lid in place in the shot chamber. Sin protruding hand or strip 64 can on Sohrotdeekel aage- j be useful to simplify the opening of the Schrotdeokele, among other things!

after that it was driven out of the muzzle of the rifle has been"

The flg. 5 shows similar interlocking parts as the Fig. 4 bit with the exception, however, that the groove 60a and the locking shoulder 62 a si the rear end of the shot chamber.

The preceding remarks "primarily related to the sealable cartridge. However, this type of ammunition requires a redesign of the conventional firearms to accommodate them To be able to shoot ammunition. You pig. 1 shows that the Gun barrel 30 has a longitudinal bore 66 through which the projectiles and the cartridge housing are propelled explosively. A rifle chamber 68, which is at the rear or the Loading end of the barrel-s is provided, has an inwardly projecting stop 70, which serves as a bearing and stop for the Shoulder 4-0 is used for the shotgun cartridge. You position of the stop 70 determines the position of the cartridge in the rifle chamber and gives the cartridge the necessary support so that the Primer can be ignited by the firing pin 72, which slides in the usual way through the rifle lock hinduron moves. Its gas seal 76 is sohematic in the Fig. 1 is shown between the rifle lock and the chamber, through which the explosion gases escape through the rear End of the gun barrel and be prevented from the hold. A similar sight is provided for the firing pin.

As an integral part of the barrel are at the point where the barrel rests on the front end of the cartridge, if this is theirs Assumes position in the rifle chamber, cutting or webs provided. These tendons 78 can have the full length of the course or be shorter and are intended to be used by the; by the explosion hit the forward flared cartridge will. Si · 8ohn «iden cause the cutting open or

"break the tubular wall part 20 of the cartridge body a plurality of places. When cut open, the cartridge body opens or it flips backwards to the usual shotgun container when it is driven out of the barrel of the rifle by the explosion. The shot cover 44 and the trapped shot is thereby removed from the body 10 freed, so that the shot protection cover as a result of the arrangement of the slots 50 and the bending points 52 like a Shell can open to let the pellets fly to the target without interference.

The closure cap can be cast in such a way that it receives built-in tension that supports the opening. After this When pouring, the lid is in a partially open position. When loading, the lid is in a closed Position, creating a tension in it which tends to open it when the resistance is removed is.

Preferably, the cutting edges 70 are in the cows of the rifle chamber or the beginning of the barrel bore where the speed is minimal since it was known to be close Cutting edges arranged at the muzzle due to the high speed be destroyed.

A modified version of the ver lockable cartridge is shown in FIG. This embodiment has a plastic body 100 with a transverse wall 118 which divides the body into a shot chamber 124 and a drive chamber 126. In one piece with the body 100 and extending radially, an annular seal 140 is provided which rests on the wall 118 and forms a tight ver ^ attlue. The Hing 140 engages in a Bingau section ΐ 0 of the rifle lock 174 and is clamped against the bolt lock 170. During the fire, the hanging 140 is sheared off the body 100 and remains in a rifle after the rest of the Patron® has been driven out of & em ®m? Ehrl & n :: . The obvious HaeMell eüesser design

9810/0495

consists in the shear ring 140 being pulled out of the rifle and must be ejected. However, this type of construction results in a determinable good resistance due to the shear strength of the plastic material *

The lockable shotgun cartridge according to Pig. 6 can be set up that the ring 140 and the body 100 during of the fire remain intact and leave the barrel. This can be achieved in that a certain clearance is provided between the ring HO and the chamber, so that the ring is not pinched, and further in that a bevel is provided on the front of the ring, so that the ring is depressed instead of sheared off.

The? Ig. Figure 7 shows a lockable cartridge similar to that after Pig. 2 with the exception that the body 200 has a transverse wall 218 that is integral with it Buffer plug 282 is provided. Of course, the buffer part can be designed differently and can be longer or be shorter depending on the desired shot and / or propellant charge. The shoulder, which like the shoulder 40 of FIG is formed, can be provided with an inwardly protruding lip edge, which the solid propellant charge in the propellant chamber holds.

The Pig. 8 shows another variation in which a body 300 has a transverse wall 318 through which the body is converted into a Shot chamber 324 and a propellant chamber 326 is divided. The propellant charge and the ignition means are similar to the execution according to Fig. 3. Different from the Pig. 3 is the procedure for locking the shot chamber and the Accommodation of the shot load in it. The tubular wall 320 of the body 300 has a Uisfangsnut 384, in which a ribbon plug 386 snaps into place. The ribbon plug 386 is preferably Made of fragile material that shatters when fired so as to avoid obstructing the flight of the shot load.

9 shows a further modification of the lockable Cartridge. This embodiment shows a one-piece body made of plastic material, with a web wall 418, which together forms with the body 400 a shot chamber 424 and a propellant chamber 426. The shot chamber 424 is with this one Execution through the transverse wall 418, through the tubular wall 420 and bounded by a transverse end wall 488 formed in one piece with it. As can be seen from Pig, 9 the end wall 488 has a plurality of transverse ones Slots 490, which extend from there in the longitudinal direction along the tubular side wall 420 as slots 49Oa and then in a circumferential series at the lower end of the shot chamber as . Slots 490b extend. This arrangement of the slots will by casting a plurality of flowers similar to petals formed segments, the number of which can be arbitrary can, for example, "2 or 4" so that when closed they form a cylinder closed at the front. The unslotted Parts 492 hold the segments to the transverse wall 418 and form gel that connects the rolled-shaped side wall 420 with the connect the rest of the body.

When the cartridge is loaded, the shot load is placed in the open container, which is then closed around the barrel to build. Then a plastic sleeve 494 is over the segment-like Wall parts pushed to keep the shape and} to complete the cartridge. When firing, the case becomes 494 cut open by the cutting edges or webs 78 (Fig. 1) in order to eliminate the holding effect achieved by the sleeve, j so that the shot can freely fly out of the muzzle. Optional For example, the sleeve 494 can be made of a fragile plastic material and can be impacted by the body Launch removed.

As for the other modifications, buffer plugs can be used by casting a collapsible portion within of the cartridge body similar to the usual Sehro ^ ffttronenpfropfen

The Pig. 10 shows a gun barrel 530 with a longitudinal bore 566 and with a first chamber stop 570, which acts in the same way as the stop 70 according to Pig. 1. A second stop 596 is mounted in the barrel bore at the level of the front end of the lockable cartridge 500, which is shown in FIG. 10 in the position for locking.

The cartridge comprises a molded plastic body 510 with an integral transverse wall 518 which, together with the body 510, forms a shot chamber 524 and a propellant chamber 526. The wall 518 contains a buffer ab-. cut 582, which is in one piece with it, similar to FIG. 7. The propulsion chamber 526 is - / - similar to the type shown in FIG. 7 and does not need to be explained again. However, the design of the shot chamber and the chamber lock are different.

The shot chamber 524 is bounded at its rear end by the transverse wall 518 and on its sides by the tubular side wall 520, which is made in one piece with the wall 518. A plurality of slots 590 in the side wall ^!

bend open and release the shotgun pellets trapped in it, after being driven from the mouth of the rifle. The closure of the open end of the tubular side wall 520 forms an easily breakable cup-shaped lid 598 which overhangs the segment-like side wall 520 grabs to keep it in shape and the shot * - to include in it. The rear end of the lid 598 is attached in some way, e.g. B. by a locking groove in the front face of bulkhead 518, of course Other methods of attaching the lid 598 to the body 510 may also be used.

When firing, the cartridge 500 reacts in the same way as previously explained. When enough pressure has developed, what usually happens immediately, the shoulder 540 is released and the entire cartridge advances in the rifle chamber. When the forward end of the cartridge propelled by the explosion against the If stop 596 hits - or at greater speed against a usual narrowing of the barrel - the zt. ? breakable lids shattered, whereby the segment-like wall 520 is free and can open as soon as it is driven out of the mouth is. Although the stop 596 is shown near the chimney, it can also be located anywhere in the barrel bore. A conical barrel narrowing can also be used with success.

The lid 598 is made of a fragile plastic material, which has adequate strength to handle has, but is smashed during shooting, among the suitable Materials should be mentioned: Polystyrene, rigid vinyl, polyamides, cellulose, acrylics, chlorinated polyether, phenol, Polysulfones and heat-fixable plastic compounds such as phenols, melamines, urea compounds · alkyds, polyesters, allyl compounds etc.

The shoulder 540 represents a "special feature of this design In addition to the braking effect, through which it can hold the cartridge in the chamber after ignition, "until a sufficient When pressure has developed, the shoulder also serves as a gas shut-off seal and a means of cleaning the barrel bore. This part of the cartridge, that is to say the shoulder 540, "consists of polyethylene or a non" breakable material. Since the Shoulder remains undamaged when shooting and is larger than the bore is, it sweeps the bore clean of the particles left behind by the fragile parts of the cartridge and any powder residue from previous shots.

Fig. 11 shows a modified lockable cartridge of the fig. Type shown 10th This construction has a fixed transverse wall 518a and a separate buffer or Ladepfropfen 599 on which is mounted under the S _c hrotladung 542 and within the shot chamber 524th

The fig. 12 shows the loaded lockable cartridge, which is shown in FIG the fig. 10 but without the details of the rifle and without the buffer section in the bulkhead.

The fig. Fig. 15 shows a modified lockable cartridge which in certain respects resembles that of fig. 10 is similar however, with the exception that the tubular side wall 520 is omitted. The breakable lid 598 is the only one Shot container with this type. Of course, this design lacks some of the advantages associated with the shot container with regard to the protective effect for the shot and for the rifle barrel bore, since the fragile lid when firing is smashed so that little or no plastic material between the shot charge 542 and the barrel bore during the There is time in which the shot can get through the barrel bore emotional. j.
