Description

Technical field
The invention relates to a single-action revolver in which the gap between the barrel bore and the cylinder chamber is sealed against leakage when fired.
BACKGROUND OF THE INVENTION
The revolver is basically made up of rigid components: a frame with a main, side lock plates and handle and movable components: a cylinder with chambers spaced around the circumference, a tap with a thumbwheel, a percussion spring, a locking lever and a pusher. Between individual shots, the cylinder is rotated so that one cylinder chamber is always aligned with the bore in the barrel. Although in a conventional revolver, the gap between the cylinder face and the barrel is minimized, the gas leaks through the gap when fired. This reduces the performance of the revolver by up to 30%, threatens the surroundings of the shooter fragments of the projectile torn from it when moving from the cylinder to the barrel and threatens the shooter itself, especially if the barrel underlay with the other hand, as usual when shooting from guns. In addition, gases striking the face of the cylinder increase the recoil of the weapon, which, in particular with heavy revolvers, can cause injury or chronic shooter degenerative disease.
This problem was solved by using a special cartridge, which was its edge inserted into the barrel, so the cartridge sealed the gap between the main and cylinder. The disadvantage of this solution is that a relatively long stroke of the cylinder in the frame must be ensured. A number of solutions are known in which the cylinder with the main spring pressure or the pressure spring is brought together. the mouths of the respective chamber and bore fit together with circumferentially sealed means, for example an interlocking circular ridge on one side and a circular depression on the other side. In US 5092068, before the shot, the axially movable barrel is pulled towards the cylinder, the chambers of which have an orifice provided with a protruding rim engaging a recess in the barrel orifice.
US 2003046851 discloses a sealed revolver having a spring-loaded ring barrel at its rear end which engages by pressure of a spring into a circumferential recess in the mouth of the cylinder chamber. In order to be able to rotate the cylinder at all, the spring pressure and thus the sealing effect cannot be too pronounced.
None of the known solutions that have reached the implementation stage can be used for large caliber revolvers with corresponding gas pressures. This problem is left unresolved in their construction.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a single-action revolver design which provides a secure sealing of the gap between the chamber and the barrel, even at the gas pressure typical of large-caliber revolvers.
SUMMARY OF THE INVENTION
This task is solved by a single-action revolver consisting of fixed parts: frame, side lock plates and handle and movable parts: cylinder with chambers, cock with mitt, drum spring, locking lever and pusher. It is based on the fact that it has a handle pivotally mounted at one end of the gate parallel to the tap, on which the drum spring rests outside of its bearing, with the other end carrying the wedge mounted in the upward groove of the side lock plate. the cam, at the other end of the link, a cam is formed at the edge thereof, engaging the mace arm to push the link to the lower position, and a tooth behind which the catch engages to lock the link in the lower position;
The cock is provided with a cam section for ejecting the retainer from the locking position and a tooth behind which the latch engages the stop of the cock in the forward unstretched position controlled by the movement of the slide.
The slide end with its other end may also carry one end of the ejection lever, the other end of which rests against the front side of the cylinder when the slide is in the down position.
In the cylinder space, the revolver may have a thrust plate displaceably mounted in the bulges of the side lock plates in which the cylinder is mounted at one end and which is provided with a firing pin and a vertical groove for the passage of the pusher.

DETAILED DESCRIPTION OF THE INVENTION
The movable parts of the revolver's mechanics are supported on three stationary carrier components forming the body of the weapon. These are the right side lock plate 1 connected to the handle, the frame 2 and the left side lock plate 3. These support members abut one another, but leave space between them in the grooves for the movement of the movable parts. For better orientation, it is possible to imagine that the movable parts are supported in four parallel layers on the functional model.
An upward groove 4 is formed in the right locking plate 1, in which the wedge body 5 forming the first layer of moving parts is slidably mounted. A horizontal wedge 6 extends from the wedge body 5 into the second layer. The front wall 7 of the wedge 5 abuts the circular turret platen 8 of the turret cylinder, which is mounted in the horizontal direction by means of pins 9 in the bulges 10 of the right side lock plate 1 and the left side lock plate 3 (not shown). The wedge 5 pushes the pressure plate 8 together with the turret cylinder (not shown) against the front of the frame 2 and thus ensures the contact of the cylinder face with the rear orifice of the barrel (not shown). The cylinder is rotatably mounted about an axis 4 in the pusher plate 8 and in the frame 2. The pusher plate 8 is further provided with a firing pin that extends through the frame 2 and a vertical through groove 12 is provided for the pusher 13 to pass at a given point in the cycle. shooting turns the cylinder.
On the right locking plate I resp. on the handle in the second layer are rotatably mounted: around the axis 02 a two-armed link 14, around the axis 03 a catch 15 whose pin 16 protrudes into the third layer, and around the axis 04 is a roll-out lever 17. It is necessary if the mouth of the chambers protrude from the front of the cylinder and the mouth of the barrel is provided with a depression from which the mouth of the chamber must be extended to allow the cylinder to rotate.
The slide 14 has a bend 18 at the end of the shorter arm on which the drum spring 19 rests. The guide bar 20 of the drum spring 19 extends through the opening in the bend 18. At the end of the longer arm the slide 14 has two horizontal projections 21. and a rear end of the ejection lever 17. A tooth 22 is further provided on the slider 14 on which the lower end of the catch 15 is supported. This keeps the slider 14 in the lower position until the cylinder is rotated. The cam 23 on the gate 14 serves to infer the downward movement of the gate 14 first to release the catch 15 from engagement with the
The tooth 22 and releasing the latch 24 from the tap 26 and then to push the gate 14 to the lower position, as will be explained below. The axis 05 of the tap 26 extends through the elongated cutout 25 in the link 14. The cutout thus allows the link 14 to move between the upper and lower positions, in which the link 14 carries the wedge 5 and one end of the ejection lever. o the pin 27 on the tap 26, acts permanently on the deflection 18 of the gate 14 and pushes it together with the wedge 5 into the upper position.
The ejection lever 17 has the task of moving the cylinder away from the front of the frame 2 after firing so that the cylinder can rotate.
In the third layer, the cock 26 with the miter 28 is rotatably mounted. On the circumference of the cock 26 there is a tooth 29 for the trigger 30 a tooth 31 for the pawl 24 and a cam section 32 to move the catch 15 through its pin 16 from the tooth 22 of the slide 14. 26 is a pivotally mounted miter 28 with two arms, of which the right arm 33 located in the second layer when pulling the miter 28 engages the cam 23 on the link 14, while the left arm 34 already in the fourth layer engages the first end of the locking lever 35 The other end of the locking lever 35 is, in the locked position, inserted into a groove provided on the cylinder. The cylinder locking lever 35 is rotatably mounted on the tap 26 about its axis by ž . Finally, on the tap 26 about the axis 6 is mounted a roller pusher 13 movable in a second cutout of the frame 2 and passing through a groove 13 in the roller pressure plate 8.
The tap 26, to which the force of the percussion spring 19 is permanently applied, resting on the pin 27, is retained in two positions during the cycle. During the tensioning of the mitt, it is initially retained by the latch 24 latched to the notch 31 and, after stretching, is retained in the extended position by the latch 30 latched by the notch 29. The latch 24, itself in the third layer, has an arm 36 located in the second layer The latch 24 disengages to allow the cock 26 to rotate when the right arm 33 of the miter 28 pushes the cam 23 and pushes the arm 36 of the latch 24.
At the moment of firing, the cock 26 is in the forward unstretched position, the slide 14 in the uppermost position where it is pushed by the drum spring 19, as well as the wedge 5 which ensures contact of the cylinder with the front of the frame 2 via the pressure plate 8. the front position and does not lie from the front of the cylinder. The cam 23 on the gate 14 is located in front of the right arm 33 of the miter 28, as well as the first end of the locking lever 35 is located in front of the left arm 34 of the miter 28. The latch 24 whose arm 37 is not in contact with the gate 14 engages the latch tooth 31 and holds the tap 26 in the forward position to prevent it from being stretched.
During the firing of the weapon by the mitt 28, the cock 26 is first retained by the latch 24 in the forward position. The miter 28 is pulled back by the shooter and its left arm 34 releases the locking lever 35 from engagement with the cylinder, thereby allowing it to rotate. At the same time, the right arm 33 of the miter 28 pushes the cam 23 of the slide 14 and moves the slide 14 somewhat downward, thereby releasing the latch 24 from the tooth 31 on the tap 26 and thereby allowing the tap 26 to move against the pressure of the percussion spring 19 to the extended position. Upon further rotation, the right arm 33 of the miter 28 further pushes the slider 14 downwardly via the cam 23, and this pushes the wedge 5 downwardly into engagement with the pusher plate 8. This releases the cylinder from engagement with the front side of the frame 2. the end, together with the wedge 5, has been pressed down, with its front end it pushes the cylinder out of contact with the front side of the frame 2 and thus allows its rotation. This occurs when the tap 26 is further rotated by means of a pusher 13 mounted eccentrically on the tap 26. The locking lever 35 engages, with its front end, another groove on the cylinder. Upon further rotation of the tap, its cam section 32 moves the catch 15 against its pin 13 out of engagement with the tooth 22 of the gate 14 and releases it. As a result, the percussion spring 19, which relies on the deflection JV of the gate 14, jumps the gate 14 into a high position. The release lever 17 releases the cylinder for forward movement, the wedge 5 engages the pusher plate 8 again and presses the cylinder against the front of the frame 2. In the end position of the cocked cock 26, the trigger 30 engages the tooth 29 on the cock 26 and position. The weapon is ready to fire.
-3GB 306969 B6
In another embodiment in which the mouth of the chambers do not extend into the mouth of the barrel or vice versa, the ejection lever 17 can be omitted. It is also possible to design without a pressure plate 10, in which the cylinder is mounted on both sides in the frame 2 and the wedge 5 is supported directly on the cylinder.
The described solution of sealing the revolver by a wedge does not require the use of special ammunition and allows sufficient dimensioning of all parts of the weapon. It is a solution suitable even for the heaviest revolvers, allowing with standard ammunition to increase performance and safety and reduce recoil. Moreover, it does not require a change in the usual traditional appearance of the revolver.
