Full Description:
BACKGROUND OF THE INVENTION 
       [0001]    First generation of cartridge revolvers was single action and they come with the detached cylinder for loading. Remove of a hot cylinder after firing was too hard and it was weak points of removable cylinders. Later models used a fixed cylinder with a loading gate at rear of cylinder and an under barrel rod to extract. In those revolvers only one chamber is exposed at a time and it waste a lots of time to unload the shells and reload the cartridges. To solve above problem, designers develop the top break and swing out cylinders with extractor to improve the revolver and make the reloading easier. But nobody try to design a revolver with ejector. Six years ago when I read an article about handguns and compare between semi autos and revolvers, I got an idea to design a revolver with ejector system. This design is result of my research. 
       BRIEF SUMMERY OF THE INVENTION 
       [0002]    This is a double action revolver with the concealed hammer. This revolver is available in .357 magnum caliber but this design is feasible on other usual calibers of revolvers. Capacity of the cylinder is 8 rounds and barrel length is 4″. For the unprofessional views, external shape of this gun is same as other revolvers but everything is different, specially 95 percent of the internal parts are totally new with different mechanism. Biggest invention on this design is the ejector system. It means, after each fire, shell pulled out of the gun. In addition to the new safety systems, this gun designed with the new safety lever. Another innovation in this revolver is disassembling and reassembling of parts just by levers, simple and without usage of any tools. I believe my design make an evolution in revolver guns.

       DETAILED DESCRIPTION OF THE INVENTION 
       [0103]    This is an automatic revolver, it means after firing, ejection mechanism pull out the shell until all cartridges have been fired. After finish of rounds, when you open the cylinder, there is no shell in the chambers. Therefore it decrease time of reloading and at minimum time we have a revolver ready to fire. I have tried to remove the weak points of revolvers in compare with the semi auto handguns. First step, I add an ejector system to this revolver. Second, I have designed a safety lever for this revolver to provide the maximum safety in addition of the new internal safety system. This design is unique among all type of revolvers and firearms because, there is no screw involve in revolver. Only the Extractor Rod has helical ridges. It reduces the production costs and makes the gun easy to repair. Usually you need special wrenches to complete disassemble and reassemble of each handgun. But In this design, complete disassemble and assemble of revolver even opening of the barrel is possible without any kind of tools. 
         [0104]    My design is double action only and hammer of the gun totally concealed. This is safer than external hammers, specially for the operator. For the easier and faster acquisition of target I have designed a three dot sight for this revolver. Self illuminated dots are highly visible in the dark areas. Also frame of this gun is drilled and ready to install the scope mounts. A good grip improves control of the gun during firing sequences. Ergonomically designed rubber grip with finger grooves provide the confidence to control of the revolver even when wet. Ninety five percent of internal parts and its mechanism are new. I have tried to design the fewer internal parts to better reliability and durability. Usage of common springs in internal parts decrease the manufacturing cost. There are no springs under stress in revolver when you storing your gun without bullet. To see the  3  view and perspective view of the gun please see  FIG. 1 to 5 . 
         [0105]    To description of the gun mechanism, first I have to explain about some of the internal parts and components. Exploded view,  FIG. 6  shows the internal and external parts of the gnu.  FIGS. 7 &amp; 8  shows the overall view and cutaway of the gun. For better understood of descriptions, name of each part come with its number according to this parts list.

       Trigger System 
       [0163]    Please refer to the  FIG. 9  and  FIG. 10 , Trigger  47  seems a lever action but it is a hinged action trigger. I have designed a unique trigger specially for this revolver. Trigger  47  is linked to the Piston  43  of Internal Cylinder  41 , by Push Rod  46 . Squeeze of the Trigger  47 , press this Piston  43  against its Spring  42 . After firing, Spring of the Piston  42  return back the Trigger  47  to the initial condition. Trigger  47  is DAO (Double Action Only) and it does these jobs: 
         [0164]    1—Cock the Hammer  36 . 
         [0165]    2—Press the Piston  43  of Internal Cylinder  41  against its Spring  42 . 
       Internal Cylinder 
       [0166]    Internal cylinder  41  is heart of this revolver and plays seven important roles in this gun. To see the components and mechanism of internal cylinder please see the  FIG. 11  and  FIG. 12 . as I described, Trigger  47  linked to the Piston  43  by a Push Rod  46  and its transfer, movement of Trigger  47  to the Piston  43  of Internal Cylinder  41  against a Compression Spring  42 . There is a Transfer Pin  44  beside of Piston  43 . It&#39;s able to move back against of a Torsion Spring  45 . In the initial condition of Piston  43  (when internal parts are at the rest) end of Transfer Pin  44  blocked by Internal Cylinders  41  jag and it can&#39;t travel back. See the  FIG. 11 . Just squeeze of Trigger  47  and move up the Piston  43  release the end of Transfer Pin  44  and it would move back. Internal Cylinder  41  unit played these important jobs:
       1—Spring  42  of Piston  43 , play role of the triggers spring and after squeeze, return it back to the initial condition.   2—Piston Bolt  FIG. 12 , locks the Firing Pin  28  at the rest condition for safety reasons (I will explain in Safety Systems regarding this action).   3—Piston Stopper  FIG. 12 , detach the Hammer  36  from the Firing Pin  28  for safety reasons (I will explain in Safety Systems regarding this action).   4—Piston Tooth  FIG. 12 , lock the Bolt and Releaser Button  31  at the firing cycle for safety reasons (I will explain in Safety Systems regarding this action).   5—Transfer Pin  44 , provide the rotary motion for the Rotator  17  in firing cycle (I will explain in Firing Mechanism regarding this action).   6—Transfer Pin  44 , block the rotary motion of Rotator  17  at the rest condition of gun (I will explain in Unit of Cylinder regarding this action).   7—Transfer Pin  44 , blocked the unadjusted Rotator  17 , when user close the open Cylinder (feed system) for safety reasons (I will explain in Safety Systems regarding this action).       
 
       Unit of Cylinder (Feed System) 
       [0174]    One of the biggest differences between this revolver and usual revolvers is this Cylinder because it&#39;s fixed in its place and doesn&#39;t rotate. The Unit of Cylinder is mounted on a hinge and swing out to the left side of frame to load or reload. There is 2 point Cylinder lockup  FIG. 13 . Capacity of this Cylinder is 8 rounds of .357 magnum cartridges. Ejector system (Ejector Tooth, Eject Port &amp; Flat Ejector Springs  18 ) is installed on the Cylinder,  FIG. 13 . In the revolver guns when you squeeze the trigger, it turns the cylinder and cocks the hammer, later release the cocked hammer to strike the primer. On the other hand, rotary motion of cylinder is before the firing of the revolver. But in this design Trigger cock the Hammer, release it to fire the gun then Internal Cylinder turn the Rotator  17  of Cylinder (Feed System). To see the component of Cylinder (Feed System), refer to the  FIG. 14 . 
         [0175]      FIG. 14 , Unit of Cylinder is included: Yoke  13 , Rotator  17  and Cover of Cylinder  20 . Cylinder is fixed in its place and just Rotator  17  is able to rotary motion. Chambers are on the Rotator  17 . To prevent of gas licking, bullet and two millimetre of its case insert to the circular part of chamber. Rest of the bullet case insert in the U-Shape of chamber  FIG. 14 . 
         [0176]    There is a Round Gear in the front side of Rotator  17 . Each tooth of the Gear has a steeply slopes edges and gently slopes in the other sides. For better understanding I add a rotated view of Rotator  17  to  FIG. 14 . 
         [0177]    Refer to the  FIG. 15 , there is a Pawl  14  and Flat Spring  15  on the Yoke  13 . Engagement of this Pawl  14  and Round Gear of Rotator played role of a Ratchet  FIG. 16 . Specific shape of the Round Gear and pressure of Pawl&#39;s Flat Spring  15  adjust the Rotator  17  at specified points. At these points Chambers are exactly aligned of the Barrel. Rotator  17  just rotates in clockwise because of Ratchet  FIG. 16 . 
         [0178]    Refer to the  FIG. 17 , There is a Latch  11  inside the Yoke  13 . Push inward of Yoke Latch  11 , against its Spring  12  engage the Latch Pin and Ratchet together and locked the Rotator  17 . There is a Hole at this point of Frame  FIG. 18  Yoke Latch  11  fixed in this place. Yoke Latch  11  play two important roles:
       1—It locked the Unit of Cylinder in the Frame exactly same as a lock bolt.   2—When you open or close the Cylinder Unit, special shape of the Frame Hole,  FIG. 18  push up the Yoke Latch  11  against of Latch Spring  12  and locked the Rotator  17 .       
 
         [0181]    Refer to the  FIG. 19  (for better understanding, Cover of Cylinder  20  is transparent in this view) at the rest condition of revolver and close position of Cylinder Unit, endpoint of Transfer Pin  44  is locked by Cylinder Jag  41  and it is not able to move back. Transfer Pin  44  engaged to Extractor Gear  19  and lock the Rotator  17  to prevent of turn it clock wise. 
         [0182]      FIG. 20  is front view of the revolver. In this condition Cylinder is completely open, Rotator  17  is free to rotary motion left side in the adjusted points and right side motion is not possible, because of Ratchet. 
         [0183]      FIG. 21 , When we close the Cylinder, Frame Hole push up the Yoke Latch  11  and pin of the Yoke Latch engage the Ratchet Gear and lock the Rotator  17  totally. In this position rotary motion of Rotator  17  is impossible. 
         [0184]      FIG. 22 , In the complete close position of Cylinder, Frame Hole let the Yoke Latch&#39;s Spring  12  to push down the Yoke Latch  11  and release the Ratchet gear, but Rotator  17  is not able to turn. In this position Ratchet, prevent the Rotator  17  from turning right and Transfer pin  FIG. 19 , prevent the rotator  17  from turning left. 
       Fire Mechanism 
       [0185]    Now I explain about the firing mechanism of this revolver. Please see the  FIG. 23 , this is Initial condition. Revolver is at rest. For better understanding of firing mechanism, Cover of Cylinder is transparent, also I add another view from back side of Cylinder to the  FIG. 23 to 32 . Situation of Cylinder Cover  20 , Rotator  17 , Transfer Pin  44 , Extractor Gear  19 , Ratchet, Ejector Port and Ejector Tooth is clear. 
         [0186]      FIG. 24 , Trigger  47  squeezed by operator. Same as double action guns, Trigger  47  is in engaged position with the Sear  37 . Pull the Trigger  47  loaded the Hammer  36  against Main Spring  35 . Trigger  47  linked to the Piston  43  of Internal Cylinder  41  by a Push Rod  46  and move up the Piston  43  in Internal Cylinder  41  against Piston Spring  42 . Transfer Pin  44  (inside of the Piston) slide up on the Extractor Gear  19  and travel back against its Torsion Spring  45 , but it is not able to turn the Rotator  17  because of ratchet. 
         [0187]      FIG. 25 , Movement is Continuous. 
         [0188]      FIG. 26 , Spring loaded Hammer  36  is in cocked position and ready to strike. 
         [0189]      FIG. 27 , Small amount of pressure on the Trigger  47 , release the tensioned Hammer  36 . Also Transfer pin  44  is in the end of Ratchet Gear  19  and latched with it by push of its Torsion Spring  45 . 
         [0190]      FIG. 28 , In this view head of Hammer  36  and Barrel Cutted for better understanding. Hammer  36  strike the Firing Pin  28  and Firing Pin strike the primer of chambered cartridge and fire the bullet. 
         [0191]      FIG. 29 , After firing, When operator release the Trigger  47 , Piston Spring  42  push down the Piston  43  and try to return back the Trigger  47  to the first position. With move down of Piston  43 , Transfer Pin  44  (now latched with Extractor Gear  19 ) move down too and turn the Rotator  17 . By turning Rotator  17 , rim of the shell slide on Ejector Tooth, pulled back and released from the circular shape of chamber. Movement of Ratchet component is clear at back view of the Cylinder. 
         [0192]      FIG. 30 , Movement is Continuous and Trigger  47  push back the Sear  37  against its Torsion Spring  38  to engage with it again. Stopper of piston push back the Hammer  36 . 
         [0193]      FIG. 31 , By rotary motion of Rotator  17 , shell goes under the Eject Port. Now shell is without protect of Cylinder Cover  20  and shoot off by pressure of Ejector Flat Spring  18   
         [0194]      FIG. 32 , Movement is Continuous and return the internal parts to initial condition. One firing cycle is complete. 
       Safety Systems 
       [0195]    First precedence for the gun designers is safety of the gun. There are six safety systems and a safety lever to maximized safety of this revolver. If you drop or roughly handle the loaded weapon, accidental discharge never happened. 
         [0196]    To prevent of accidental discharge, Firing Pin  28  has a Tooth, it is engaged and blocked by Piston Bolt when it is at rest  FIG. 33 . 
         [0197]    Firing Pin  28  unlocked when the Trigger  47  is pulled by operator  FIG. 34 . Because pulling of the Trigger  47 , move up the Piston  43  and Piston Bolt doesn&#39;t obstruct the Firing Pin Tooth. 
         [0198]    The Hammer  36  itself cannot contact the Firing Pin  28  to prevent accidental discharge  FIG. 35 . There is a Stopper in the back side of Piston  43  and it isolates the Hammer  36  from Firing Pin  28 . 
         [0199]    By pull the Trigger  47  and move up the Piston  43 , Stopper moved up too  FIG. 36 . [ 0142 ] When the Hammer  36  strikes the Firing Pin  28 , Stopper goes exactly in the Hammer&#39;s Hole and it is not between Hammer  36  and Firing Pin  28 .  FIG. 37 , For better understanding head of Hammer shows cutted at  FIGS. 37 &amp; 38   
         [0200]    After discharge and release of the Trigger  47  by user, Spring of Piston  42  pushed down the Piston  43  and Stopper.  FIG. 38 , Inclined surface shape of Stopper slides up and push backward the Hammer  36 . In this position until initial condition, Stopper is between Hammer  36  and Firing Pin  28  and isolate those again. 
         [0201]    To prevent accidental opening of Cylinder Unit in the firing cycle, I add another new safety device to this revolver. When Trigger  47  is at rest, you can push the Releaser Button  31  against its Spring  32  and open the Cylinder to reload or unload the weapon  FIGS. 39 &amp; 40 . 
         [0202]    By squeeze of Trigger  47  and move up the Piston  43 , Pistons Tooth locked the Bolt and Releaser Button  31   FIG. 41 . Until end of firing cycle and return of the Trigger  47  to initial condition, Releaser Button  31  will be locked. 
         [0203]    Misfire (Failure to Discharge) is an important problem it sometimes occurred in automatic firearms. Damaged cartridge is main reason of this problem. Misfire caused to malfunction, stop, and even damaged of the gun. To prevent of this problem I have designed a new safety system. 
         [0204]    There is a Dent on frame of this revolver in the back side of cylinder  FIG. 42 . When Ejector Tooth, pulls back the shell, end point of the shell goes exactly in this Dent  FIG. 43 . If the cartridge doesn&#39;t fire because of any problem in primer or powder, after pull back of cartridge by Ejector Tooth, Flat Ejector Spring (under the shell) is not able to shoot out the cartridge because bullet is still in the Chamber and it is stuck the cartridge. Rotary motion of the Rotator  17  and special shape of Dent (same as inclined surface) push forward the damaged cartridge in chamber to the initial condition  FIG. 44 , and it doesn&#39;t make problem for the next firing cycle. After firing, operator can use the extractor to unload the damaged cartridge. 
         [0205]    If the Cylinder Unit does not closed completely and latched in its place, firing of the gun is impossible because of a new safety system. Action of the Trigger is depending on the Cylinder condition. Cover of the Cylinder  20  has two gaps on its Hinge  FIG. 45 . 
         [0206]      FIG. 46 , There is a Tooth on the front side of Trigger  47 . When Triggers Tooth and Hinge Gap are alignment of each other, Trigger  47  is able to work. This is possible when the Cylinder is in close condition or complete open condition  FIG. 47 . 
         [0207]    When you open the Cylinder  FIG. 48 , by swing out of Cylinder, Hinge Gaps turn from front of Triggers Tooth and edge of the Covers Hinge, block the Triggers Tooth. 
         [0208]    In the complete open condition of the Cylinder another gap of Cylinder Hinge is in front of Trigger Tooth and action of Trigger  47  is possible again  FIG. 49 . 
         [0209]    Lack of the alignment between chamber and barrel is a dangerous condition in the revolver guns. Sometimes when the operator close the cylinder quickly with the flick of the wrist, the cylinder latched but chamber and barrel are out of alignment and it caused bullet damage, stuck of the bullet and even explode of the cylinder. It is the weak point of swing out cylinder designs. This problem never occurred at this design because Cylinder Ratchet keeps the Rotator at Adjusted points  FIG. 16 . If the chamber is not aligned to the barrel because of any problem in the cylinder, you can&#39;t close the cylinder completely and when the cylinder is not latched in its place trigger doesn&#39;t action because of above safety system. Refer to the line [0148]. 
         [0210]    As I described Transfer Pin  44  is locked at the rest condition (by Internal Cylinder Jag)  FIG. 50 . 
         [0211]      FIG. 51  Shows the adjusted place of Rotator  17  when Cylinder is open. Round Gear of Extractor is adjusted to never become engage with Transfer Pin  44  at the closing of Cylinder  FIG. 52 . 
         [0212]    when the Rotator  17  is in unadjusted place,  FIG. 53 , Round Gear of Extractor is unadjusted too and Transfer Pin  44  blocked it at closing position  FIG. 54 . If the Cylinder can&#39;t completely close, Trigger doesn&#39;t work. 
         [0213]    The Safety Lever  27 , situated above Releaser Button  31  in the back side of revolver  FIG. 55 . When the operator focused on the sights to aim the target, Safety lever  27  is under view of operator and the user understand the gun is in fire mode or not, without looking at another place except target. Action of this lever is easily possible with thumb of the firing or supporting hand. Usage of this lever is comfortable for both right hand and left hand operators. Refer to  FIG. 56 , Components of Lock System  34  are: Lever  27 , Lock Bolt and Flat Spring  33 . Also there is a tooth beside of Hammer  36  to engage with Lock System. 
         [0214]      FIG. 56 , I add a reverse angle view from lock system to  FIG. 56 to 58  for better understanding. In this condition  FIG. 56 , revolver is in fire mode. Lock Bolt is in up position and doesn&#39;t block the Hammer Tooth. 
         [0215]      FIG. 57 , By turn up of the Safety Lever  27  against pressure of its Flat Spring  33 , Lock Bolt, it linked to the Safety Lever Button  27  turn down, engage with Hammer Tooth and lock it. 
         [0216]      FIG. 58 , Now revolver is at safe state. Lock Bolt is in front of Hammer Tooth, against of Hammer  36  movement and it prevent the firing mechanism from moving. 
       Load and Reload of the Revolver 
       [0217]    You have to load the gun to prepare it to use. Loading of this revolver is simple. To Load the gun: Point the gun in a safe direction.

         [0219]    Hold the Releaser Button  31 , push the Cylinder  20  and Swing it out completely from the left side of the revolver  FIG. 60 . 
         [0220]    You can place individual cartridges in to the chambers or load the gun with a speed loader at once. You should push the cartridges to the chambers firmly because flat ejector springs are against insert of cartridges  FIG. 61 . 
         [0221]    Push the Cylinder  20  in to frame completely and close it  FIG. 62 . 
         [0222]    To unload the gun: Point the barrel in a safe direction.

       Disassemble and Reassemble of the Gun 
       [0227]    When you want to disassemble a revolver, at least you need a screwdriver to remove the side plate. After that you have access to the internal parts. Specific wrench is necessary to release the barrel from the frame. I have designed a revolver same as automatic guns, it&#39;s disassembled by levers. 
         [0228]    Even for complete disassemble of semi autos you need the three or four kind of tools, but in my design you are needless of any tools to assemble or disassemble of the gun. Also replacing of the defective parts can be done easily in least time. 
         [0229]    Refer to the  FIG. 7 , compression springs no.  4 ,  9 ,  12 ,  24 ,  29 ,  32 ,  54  and torsion springs no.  38  &amp;  45  are same to decrease the manufacturing cost.
