Description

Drum mechanism of single action revolver

Technical field

The invention relates to the percussion device of a single-action revolver comprising a cock with a percussion strut, a trigger, a locking lever and a pusher.

BACKGROUND OF THE INVENTION

The percussion device of a single-action revolver consists of a tap which is rotatably mounted in the frame of the weapon and on which the percussion ring generally supported in the stock rests, and further consists of a trigger which directly or indirectly retains the tap in the cocked position, generally by its projection It rests on the tooth on the lower cam of the tap. In addition, the revolvers are provided with a locking device that blocks the rotation of the cylinder after cocking, thus in a position where the bottom of the cartridge is set against the firing pin. Such a solution is described in FIG

US 4228608. The spring-loaded double-reversible V-shaped arresting lever here extends through the front end into individual recesses made around the circumference of the cylinder. The rotation of the cylinder is enabled when the projection on the underside of the tap pushes the upper end of the arresting lever into the forward position during stretching, thereby pulling the front end out of engagement in the recess.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a new concept of the percussion device, in particular a new design of the cylinder arrest mechanism.

SUMMARY OF THE INVENTION

This object is solved by a single-action revolver drum consisting of a cock with a percussion strut, a trigger, a locking lever and a pusher, which consists in that the percussion strut is designed as a torsion spring mounted around the axis of the cock. the rear side of the locking lever rotatably supported by one end on the trigger and the other end extending into the recess in the rear face of the cylinder or the driver disc, the drum strut resting on the locking lever in the plane between the trigger seating on the frame and the locking lever on the trigger.

In a preferred embodiment of the revolver according to the invention, the arresting lever is provided with a firing pin at the end extending into the rear face of the cylinder or the driving disc.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be further elucidated by means of the drawing, in which Fig. 1 is a left side view of an embodiment of a revolver according to the invention, partly in section, and Fig. 2 is a right side view of the same embodiment, also partly in section.

DETAILED DESCRIPTION OF THE INVENTION

The single-action revolver according to FIGS. 1 and 2 consists of a frame 1 with attached main 2 and a stock 3. The frame 1 is rotatably mounted with a cylinder 4 with cartridge chambers, on the rear wall of which a ratchet ring 5 is provided. it is supported on a plate 6 which is part of the frame 1 and protrudes from it rearwardly. The percussion device consists of a tap 7 pivoted about the axis 8 and provided with a torsion drum strut 9 wound around the axis 8 of the tap 7. Its upper end bears against the back of the tap 7, while the lower end presses against the locking lever 10. rotatably mounted on the trigger 11, its upper end is formed into the firing pin housing 12 and passes through the firing pin 13. The firing pin housing 12 extends through the frame 1 and fits into one of the recesses 14 arranged in a circle at the rear face of the cylinder 4. 11, is mounted on the plate 6 of the frame 1 astride, the locking lever 10 is received in the recess 15 of the trigger 11. The tap 7 - see FIG. 2 - is disposed between the plate 6 and the bracket 16 formed on the plate 6. 9 and bracket 16 and is supported by a projection 17 formed on the locking lever 10 and extending below the plate 6. An important part of the cock is the cam 18 on its front. days bottom side. It has two teeth 19, 20: the first - in the sense of cocking - the release tooth 19 and the second cocking tooth 20. The trigger 11 on the right side of the weapon extends up into the tongue 21 which slides when the cock 7 is pulled on cam 18 or over its teeth Finally, a pusher 22 is mounted on the left inner side of the tap 7, which engages the ratchet ring 5 on the rear face of the cylinder 4. In another embodiment of the revolver according to the invention, a carrier disc provided with the ratchet ring 5 and recesses 14.

By pressing the tap 7, which is under pressure from the upper end of the torsion strut 9 supported from the rear into the recess of the tap 7, the upper end of the drum strut 9 rotates about the axis 8 of the tap 7 and its lower end pushes forward with more force a locking lever 10, which is located below the level of the trigger 11 and above the level of the locking lever 10 on the trigger 11. By the pressure transmitted by the locking lever 10 to the trigger 11, the tongue 21 of the trigger 11 engages the cam 18. When the tap 7 is rotated, the tongue 21 moves beyond the release tooth 19. At this time the trigger 11 jumps forward and pulls the lower part of the locking lever 10. thereby causing the upper end of the locking lever 10 to move backwards and thereby releasing the sleeve 12 from the recesses 14 in the rear face of the cylinder 4. Thus, the pusher 22 can rotate the cylinder 4 by one pitch during further stretching of the tap 7 by ratchet ring. Behind the release tooth 19, the cam 18 has an ascending characteristic and pushes the tongue 21 of the trigger 11 forward. The trigger 11 and the lower part of the locking lever 10 are pushed backwards; the upper end of the locking lever 10 then forward. This results in the cylinder 4 and / or the cylinder 4 being locked again. by engaging the sleeve 12 in the nearest further recess 14 on the rear face of the cylinder 4. By further turning the tap 7, the tongue 21 overcomes the tension bar 20, engages behind it and thereby retains the tap 7 in its extended position. By pressing the finger on the trigger 11, the trigger 11 rotates about its axis, the tongue 21 of the trigger 11 releasing the tooth 20, causing the strut 12 to eject the cock 7 against the movable firing pin 13 in the housing 12 on the locking lever 10.

J

The lower end of the drum strut 17 still acts on the arresting lever 10, the upper end of which, respectively. the sleeve 12 is pushed into the recess 14 - the cylinder 4 remains locked.

The firing pin 13 may be a fixed part of the tap 7 or the locking lever W, but preferably it may be slidably mounted in the bore of the housing 12 at the end of the locking lever 10, where it is secured against falling out or springing.
