RU2289081C2 - Revolver for noiseless cartridge - Google Patents

Abstract

FIELD: armament equipment, applicable in revolver weapon.

SUBSTANCE: the revolver for a noiseless cartridge has a frame, drum with a rocker and extractor, firing mechanism. The novelty in the revolver is in the fact that it is provided with a drum locking mechanism, which represents a stop made in the form of a double-arm lever with correlation of arms 1:5, one of its arms is engageable with the trigger, and the other - with the drum retaining the latter from onward motion at the instant of a shot producing a clearance between the frame and the front end face of the drum thus making it possible a free turning of the latter.

EFFECT: simplified construction of the revolver and enhanced its operating characteristics.

Description

The invention relates to weapons technology and can be used in revolving weapons.

Known revolvers containing a frame, a drum with a rocking chair and an extractor, a trigger mechanism, a barrel. Such a device has, for example, a revolver OTs-01 "Cobalt", see [1].

The design of the revolver does not provide axial movement of the drum, so there is no need to hold the drum from axial movement by an additional mechanism.

Also known revolver "Nagan", selected as a prototype, see [2]. This revolver contains a frame, drum, barrel, trigger mechanism. A feature of the revolver is the availability of a device for sliding the drum along with cartridges when fired at the breech of the barrel in order to prevent breakthrough of powder gases between the drum and the barrel.

However, this scheme leads to an increase in the descent force, to complicate the design of the revolver, to complicate the manufacture of the frame.

The invention solves the problem of improving operational characteristics by providing free rotation of the drum of a revolver firing silent cartridges in which powder gases remain inside a closed cartridge case when fired.

To solve this problem in a revolver for a silent cartridge containing a frame, a drum with an extractor having axial movement along a rocking chair, a trigger mechanism, new according to the invention is that the revolver is equipped with a drum locking mechanism, which is an emphasis made in the form two shoulders of the lever with a ratio of shoulders 1: 5, one shoulder of which interacts with the trigger, and the other with the drum, keeping the latter from moving forward at the time of the shot. Thus, creating a gap between the frame and the front end of the drum, which allows free rotation of the drum when releasing the trigger and then pressing it.

The design of the locking mechanism is simple and reliable. The emphasis keeps the drum from moving forward at the time of the shot, preventing the drum from abutting into the frame and jamming, which allows the drum to freely rotate around the axis of the rocking chair. The ratio of the shoulders 1: 5 is chosen empirically and is optimal.

The invention is illustrated in the drawing, which shows a revolver under a silent cartridge in the context.

The revolver for a silent cartridge includes a drum 1 mounted in a frame 2, a drum stop 3, a drum stop 4, a trigger 5. A cartridge 6 is installed in the drum 1. The drawing also shows: pos. 7 - axis of the drum stop, pos. 8 - axis of the trigger.

When you press the trigger 5, the latter rotates around its axis 8, interacting with the emphasis of the drum 4. The emphasis of the drum 4, turning in turn on its axis 7, abuts the drum 1 with the cartridge 6 located in it and preventing the drum 1 from moving forward at the moment shot that provides the ability to rotate the drum 1 when you repeatedly press the trigger 5.

The company manufactured a batch of revolvers of the claimed design and tested with a positive result. Currently, the revolver is adopted and produced in small batches.
