Description

CASE-LESS AMMUNITION FIREARM

Technical Field

The invention relates to a firearm capable of firing any type of case-less ammunition.

Background Art

The history of the case-less ammunition firearms came from the need for:

- Reducing the cartridge size to allow the magazine to contain more.

- Reducing materials which will reduce the manufacturing cost.

- Reducing the cartridge weight to allow the shooter to carry more.

- Eliminate jamming problem produced by the projectile shell case.

- Gaining high firing rates as the shell case ejection process has been eliminated.

The prior art can be limited to the following categories according to the cartridge type used by the firearm:

1-Firearm using solid propellant encasing both the projectile and the primer and mechanically ignited:

The first example of this type is the "Heckler and Koch Gl 1 assault rifle and its

ammunition".

The firearm was partially described in the United States patent" 4078327" and the ammunition was as the one described in the German paten '3834925".

This firearm was using horizontally installed magazine above the barrel housing and a 90 degrees rotary member for feeding cycle and to hold the cartridge inside it until ignition or using this rotary member as a part of the ejection mechanism.

The Heckler and Koch Gi l assault rifle design was brilliant but limited to one type of ammunition to fire which lead to the following disadvantages:

- The reduction of size and cost was not offered by this type of ammunition.

- The propellant is located outside the cartridge which does not provide the safety element even though the high ignition temperature feature used.

- Any deformation of the cartridge will produce misfiring or jamming because firing the cartridge was depending on its shape.

- The cook off phenomenon wasn't eliminated even though the design was using odd magazine position exposed to air and odd rotary member in between the magazine and the chamber.

- The rotary member misdirection by a single degree will lead to a catastrophe. The second example is the "LSAT light machine gun" which was designed in two versions one to fire"case-less telescopic ammunition" and the other design was firing "cased telescopic ammunition" the model that was firing case-less telescopic ammunition used a belt of ammunition as a feeding system to avoid cook off phenomenon and feeding problems but its ammunition disadvantages is still existed.

2- Firearm using solid propellant encasing both the projectile and the primer and electronically ignited:

The example for this type is the "VOERE VEC-91 rifle and its VOERE ammunition" and this type of weapons main problems are:

- The ignition depends on electronics supplied by dry cell batteries or other source as a power supply which would lead to misfiring due to low battery or any other electronic malfunction.

- The VOERE VEC-91 designers have eliminated cook-off phenomenon by not supporting automatic firing in the weapon.

3- Firearm using hollow metallic cartridge encasing both the propellant and the primer:

The example for this type is the "Benelli CB-M2 submachine gun and its 9mm AUPO ammunition "which partially was described in the united states patent "4395838" and another example is the " Gerasimenko VAG-73 pistol and its ammunition ",

And these types of weapons main problems are:

-The small port used for the propellant gases to go through it after ignition which was eliminated by the "CB-M2 submachine gun" by using upper ignition mechanism and big back port for propellant expanding gases to pass through.

-The hollow cartridge walls must be thick enough to bear the pressure and heat.

The current invention of case-less ammunition firearm is capable of:

- The firearm barrel can be replaced so as the weapon can accept any caliber and any shape of ammunition.

- Any type of case-less ammunition can be fired through the firearm if it contains the two rear grooves and the front smooth edges needed in feeding and ejection.

- The firing mechanism and the ejection mechanism are applicable to any type of firearms whatever it was rifle, pistol or even a machine gun or else.

- The mechanism is pure mechanical and no electronics involved. - Very tight accurate design due to the built-in protrusions in the lower and upper frame which acting as guiding rods besides to the removable guiding rods.

- High firing rate.

- Aiming accuracy as the barrel is not movable and no slide exist.

- Ordinary magazine position with ordinary magazine release button.

- The ordinary dimensions and shape of the firearm (not so huge or complicated).

- Limited deformation away from the rear grooves will not matter.

- Cook off phenomenon nearly eliminated.

Disclosure of the Invention

The invention is a case-less ammunition firearm that has the ability of firing any type of case- less ammunition only with two conditions the first is that the cartridge design must provide smooth slide between the bullet catchers and contains the two grooves at its end needed for firing and ejecting purposes and the second condition is that the barrel used must be dimensioned for this type of ammunition.

The firing mechanism is using a barrel 8 with two bores the main bore 78 is used for the cartridge 42 to be held in it before ignition and pass through it after been ignited and the small bore 73 is above the main bore and used for releasing the cartridge held in the main bore78.

Also the barrel 8 contains a slot at each side passing through those two bores with a separating thick metal between the two bores (the bores are not opened to each other as shown in FIG. 21, FIG. 25, and FIG. 29).

The right slot 68 is dimensioned for the right bullet catcher 9 to fit its front edge inside it and the left slot 71 is dimensioned for the left bullet catcher 10 to fit its front edge inside it (both slots are identical and both bullet catchers are identical).

The right bullet catcher and the left bullet catcher and their springs are assembled in the lower frame 2 inside the left and right protruded housing 45 while the front edges of the right and left bullet catcher fit inside the barrel slots.

After the right bullet catcher 9 and left bullet catcher 10 and their springs are assembled between the barrel 8 and the lower frame 2 inside the right and left protrusion 45, the right bullet catcher and the left bullet catcher front edges form an arc shaped protrusions intercepting the bores of the barrel from each side (as shown in FIG. 30). The formed arc shaped protrusions of the right bullet catcher and the left bullet catcher in the lower main bore 78 is used for fitting inside the first groove of the cartridge 140 and hold the cartridge in its position inside the barrel main bore 78 while the upper two arc shaped protrusions formed by the left and right bullet catcher inside the upper small bore 73 of the barrel 8 is used for releasing the cartridge at the same time it is ignited by the means of using a striker 13 with two built-in pins in its front.

The striker lower pin 96 is short and acting as a firing pin that passes concentrically to the barrel main bore 78 igniting the cartridge 42 and the upper pin 98 is long and passes concentrically to the barrel upper bore 73 separating the right bullet catcher 9 and the left bullet catcher 10 which will force the lower arc shaped edges at the lower bore 78 to leave the first groove of the cartridge 140 as they retreat towards the sides of the firearm and free the cartridge 42 at the same time it is ignited by the means of the perfect length difference between the striker upper pin 98 and lower pin 96.

And the invention also contains a failsafe routine as the cartridge first groove 140 rear edge is chamfered 132 (as sown in FIG. 50 and FIG. 51) which will allow the ignited cartridge to go out through the barrel main bore even if a part of the arc shaped edges of the right and left bullet catcher is stuck inside the cartridge first groove 140 also the cartridge 42 is not allowed to go backwards towards the shooter due to that the first groove 140 opposite wall is totally straight.

The design will not allow the two arc shaped edges that intercepting the main bore and formed from the two bullet catchers to fit inside the rear second groove 141 due to the small width of the rear groove and also the edges of the bullet catchers will not be allowed to back to its position again (catching again) until the cartridge leaves the zone and the striker 13, feeder 14, and the parts assembled to them are blown back by the expanding propellant gases and that's due to the tall striker upper pin 98.

Also the firearm contains a feeder 14 that used for pushing a round 42 inside the barrel 8 by pushing it with its lower edge to out from the magazine 38 and lie on another part called bullet bridge 21 which represents an inclined plane to slide the cartridge on it up to the barrel main bore 78 then the feeder 14 finishes its way and pushes the cartridge in its position inside the barrel main bore 78 held in the desired position by the left and right bullet catcher.

The feeder 14 and the striker 13 are uniquely assembled to the lower and upper frame and together through protrusions, grooves, slots, and through two removable guiding rods the right guiding rod 25 and the left guiding rod 26 passing through the feeder right hole 1 16 and the feeder left hole 1 17 which will provide a very accurate position for every part inside the firearm also that will reduce friction and vibration issues.

Also the feeder body 14 contains two extractors one at the right 15 and the other at the left 16 assembled to its front and inside its frame with two springs the right extractor spring 17 and the left extractor spring 18 and also two pins the right extractor pin 19 and the left extractor pin 20 which are used for assembling the extractors to the feeder body while the two extractors are able to move up with a limited distance and down again by their springs forces, the extractors front edges rest freely inside two cuts in the barrel front (right cut 74 and left cut 72) and so as to those extractors to be active and extract a round backwards they have to be in the lower position and engage to the cartridge rear groove 141 which will be occurred only if the striker 13 was in the rear position and far from the feeder front and that can be achieved by using a part called the puller (FIG. 27 ) consists from six parts when this puller is pulled its front part protrusion 84 pulls the striker back with it which will force the extractors to rest to its lower position by the springs forces while the puller releasing pin 5 has already penetrated the barrel upper bore73 and separated the left and right bullet catcher and freed the cartridge where after this point the same protrusion 84 in the puller front body that pulling the striker backwards intercepts with the feeder edge 107 and the striker, feeder, and the extractors become connected to the cartridge and go backwards until the front of the cartridge has reached no metal to lie on it inside the main bore 78 and starts to incline and slide down on the partially inclined face of the feeder and before the end of the barrel where the front of the cartridge inclines on the barrel edge 77, the cartridge will become fully down on the feeder partially inclined face and free from the fist of the upper extractors where the rear groove of the cartridge becomes connected to a small protrusion on the feeder front face 109 acting as a built-in extractor by this point the gate 41 must been opened and the ejection button 24 on the side of the firearm must been pressed and the bullet bridge 21 went down with the pressed button as they are connected to each other and that will force the accurately positioned falling cartridge to slide on the bullet bridge 21 between the lower frame filleted faces 67 then to the lower frame hole 62 and leave the firearm.

And by releasing the puller rear part 4 and the ejection button everything will reposition to their original by their own springs and to understand this process with illustrated figures the procedures of feeding, firing and ejecting is as follows The sequence of feeding a Round inside the barrel is as follows:

Once the puller (FIG. 27) is pulled backwards its half circle cut in the lower non complete half pyramid protrusion 84 grabs the striker 13 with it backwards from the pin shaped protrusion 99 inside the limited path represented by the slot 108 and the retreating striker will force both the right extractor 15 and the left extractor 16 to rest down due to the right extractor spring 17 and the left extractor spring 18 (the extractors were pushed up by the striker right protrusion 100 and the striker left protrusion 97 that fits inside the feeder right groove 1 13 and the left groove 1 12 ) until another point where the flat edge of the non complete half pyramid protrusion 84 located at the puller front part 3 grabs the feeder 14 from its flat edge 107 also backwards with it and at this point the puller releasing pin 5 is concentrically inside the upper bore of the barrel 73 and already has separated the right bullet catcher 9 and the left bullet catcher 10.

After the feeder lower edge passes the magazine 38 the puller is released to reposition again due to the tension spring 7 and then the feeder lower edge pushes a round forward to the bullet bridge 21 which provides an inclined path for the round to climb on it to the barrel main bore 78 and the round 42 pushed by the feeder pushes the two bullet catchers until their arc shaped edges 80 rest inside the cartridge first groove 140 by this point the feeder front face is coincident with the barrel face and the striker 13 has been stopped at the point where the striker stopper 32 intercepts it by settling its front edges inside the striker right groove 103 and the striker left groove 93.

The sequence of firing a round is as follows:

After feeding a Round inside the barrel as shown in the procedures above where the cartridge is held in the desired place due to the bullet catchers arc shaped edges and after pulling the trigger 30 which pulls the striker stopper 32 with it by the means of the trigger link 31 ,the way of the striker 13 becomes clear to move towards the barrel 8 and the striker right protrusion 100 and the striker left protrusion 97 pass through the feeder right groove 1 13 and the feeder left groove 1 12 until the point where the striker protrusions lift up the extractors from their filleted edges 1 10 leading the extractors to disengage to the cartridge rear groove 141 then the strikers front pins concentrically penetrate the barrel bores while the upper pin 98 separates the left and the right bullet catcher and free the cartridge, the lower pin 96 ignites the cartridge primer at the same time.

The sequence of ejecting a round is as follows: After the feeding process is achieved and a round 42 is inside the barrel 8 and the striker right protrusion 100 and the striker left protrusion 97 are partially lifting up the right and left extractor at this point the ejection button 24 at the side of the firearm lower frame 2 is pressed down grabbing the bullet bridge 21 with it and the gate 41 is already opened by pulling it towards the firearm front then the puller is pulled backwards and the half circle cut in the lower non complete half pyramid protrusion 84 located at the puller front part 3 grabs the striker 13 with it backwards from the pin shaped protrusion 99 and forcing the right extractor 15 and the left extractor 16 to rest down due to the right extractor spring 17 and the left extractor spring 18 (the path of the extractors up and down is limited to the height of the slot located at the top of each extractor) and then the extractors settle inside the cartridge rear grooveHl where the puller releasing pin 5 has already penetrated concentrically the upper bore 73 and separated the right and left bullet catcher and freed the cartridge which goes back with the feeder extractors assembly until it reaches the barrel throat 77 where its front starts to inclines down by the gravity force and slide on the feeder front face due to the inclined cut shown in (FIG. 33 A) then only the feeder lower protrusion 109 settles inside the cartridge rear groove 141 and before the feeder lower edge reaches the magazine 38 the cartridge falls accurately on the bullet bridge 21 which provides an inclined plane that forces the cartridge to slide down on it between filleted faces 67 of the lower frame then outing through a hole 62 in the lower frame and leaving the firearm through the gate 41 and by releasing the puller and the ejection button 24 everything goes back to its original position by the spring force of the ejection spring 23 and the tension spring 7.
