BACKGROUND OF THE INVENTION 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 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 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.
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.
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 & 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 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:
1—Cock the Hammer 36.
2—Press the Piston 43 of Internal Cylinder 41 against its Spring 42.
Internal Cylinder 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'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'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) One of the biggest differences between this revolver and usual revolvers is this Cylinder because it's fixed in its place and doesn'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 & 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.
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.
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.
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'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.
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.
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.
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.
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.
FIG. 22, In the complete close position of Cylinder, Frame Hole let the Yoke Latch'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 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.
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.
FIG. 25, Movement is Continuous.
FIG. 26, Spring loaded Hammer 36 is in cocked position and ready to strike.
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.
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.
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.
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.
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
FIG. 32, Movement is Continuous and return the internal parts to initial condition. One firing cycle is complete.
Safety Systems 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.
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.
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't obstruct the Firing Pin Tooth.
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.
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'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 & 38
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.
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 & 40.
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.
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.
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'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't make problem for the next firing cycle. After firing, operator can use the extractor to unload the damaged cartridge.
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.
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.
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.
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.
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't close the cylinder completely and when the cylinder is not latched in its place trigger doesn't action because of above safety system. Refer to the line [0148].
As I described Transfer Pin 44 is locked at the rest condition (by Internal Cylinder Jag) FIG. 50.
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.
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't completely close, Trigger doesn't work.
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.
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't block the Hammer Tooth.
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.
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 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.
To open the Cylinder, push the Releaser Button 31 inward FIG. 59.
Hold the Releaser Button 31, push the Cylinder 20 and Swing it out completely from the left side of the revolver FIG. 60.
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.
Push the Cylinder 20 in to frame completely and close it FIG. 62.
To unload the gun: Point the barrel in a safe direction.
To open the Cylinder, press the Releaser Button 31 inward FIG. 63.
Hold the Releaser Button 31, push the Cylinder 20 and Swing it out completely from the left side of the revolver FIG. 64.
Press the Push Rod 7, firmly and release all of the cartridges. Allow push rod to return forward under its spring pressure FIG. 65.
Push the Cylinder 20 in to frame completely and close it FIG. 66.
Disassemble and Reassemble of the Gun 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.
