Definitions
- Movable connection devices for silencers and suppressors so-called momentum connections or momentum boosters, are known in various embodiments. They are typically used where the additional weight of the suppressor or of another accessory that is attached directly to the barrel would prevent the normal firearm function introduced by the shooting impulse.
- the cycling of the weapon ejection of the empty shell and the introduction of a new bullet into the chamber
- Reducing the firing impulse by dissipating gasses in a suppressor reduces the recoil and blowback counter-actions and makes cycling of the firearm more difficult or even prevents cycling altogether.
- momentum boosters can be added as an insert into an existing suppressor device in order to allow enough counter-action from the firing impulse to cycle the firearm.
- these movable momentum booster parts have several disadvantages.
- the booster must be inserted in the suppressor in order for it to function. Once inserted, it allows full cycling, but the noise of the ejected bullet shell falling onto the floor remains. Converting to a quiet suppressor mode required unscrewing the suppressor, removing the booster, and replacing the suppressor for single-shot action.
- the movable momentum booster part is exchanged for a fixed connection part in the suppressor, or is removed from the suppressor. This is time- consuming and cannot always be performed without tools.
- the invention provides a solution to the need to remove or exchange a momentum booster from a suppressor in order to switch from a fully automatic operation mode to a silent, single-shot operation mode.
- a new locking device is described here, which consists in part of a thick-walled shell provided with an axial stepwise bore and on the outside is turned in steps, into which a momentum booster part that consists of another shell and a thick collar disk is introduced coaxially.
- the collar disk defines the depth of penetration (or movement of the momentum booster part) and on the opposite end it is held in position by a spring-loaded or spring-cushioned guide part and a threaded collar.
- the thick-walled sleeve and the thick collar disk are each provided with an identical outer thread, the axial movement potential of the momentum booster part can be locked by turning the thick collar disk of the threaded collar onto the thick-walled sleeve.
- the operation of the suppressor can easily be changed from a recoil booster-operating mode for full automatic or semi-automatic cycling, into a single shot, silent operation mode. The time-consuming removal of parts from the barrel end is no longer required.
- one object of the present invention is to avoid the disadvantages of the existing, complicated recoil booster devices and to create a simple locking device that functions rapidly and reliably without additional parts.
- the locking device can be actuated from a ring or lever or other device mounted on the exterior of the suppressor and engaging a threaded collar that holds the momentum booster in a locked position. In this way, the operator simply turns a ring or lever to change the operation mode of the suppressor.
- a locking device claimed in independent claim 1 for movable parts of suppressors or silencers on semiautomatic and fully automatic weapons, comprising a mounting ring and an axially movable momentum part that is supported within a column sleeve of the silencer, whereby a pressure spring, introduced between the sleeve holding the pressure spring and the exterior of the momentum part, applies pressure on the one hand against a projection of the column sleeve and on the other hand onto an index disk.
- the pulse part has at least one interlocking cam and the mounting ring has a side surface with an opening designed in such a way that, in a first position of the mounting ring, the side surface blocks the interlocking cam and in a second position of the mounting ring releases the interlocking cam.
- the invention includes any one of many possible designs of a suppressor that can be manually adjusted from a recoil boosting mode for automatic firing and a silent mode without removing the suppressor from the barrel.
- the suppressor of the invention includes an integral recoil booster that can be moved into a locked mode, or unlocked into an operating mode.
- the suppressor, recoil booster function, or devices of the invention can include a locking and unlocking momentum part or assembly that operates by the pressures upon firing the weapon.
- an adjustable suppressor for a semiautomatic and fully automatic weapon of the invention can encompass a design having a central channel for the passage of a projectile and having multiple regions for the flow of gas upon firing the weapon. The channel and these regions can be those conventionally found on any available suppressor or silencer design.
- the adjustable suppressor also includes a mounting ring, located at the end for connecting the suppressor to the barrel of a weapon, and an axially displaceable momentum assembly (sometimes called a momentum part herein) positioned at one end of the suppressor.
- the momentum assembly comprises a pressure absorbing and releasing device, such as a spring as conventionally used on recoil boosters.
- the device or spring can be positioned between a projecting sleeve on one end of the momentum assembly and an index disk at the other end, and is within the outer sleeve of the suppressor.
- the momentum assembly can include a bore for attaching to the barrel of a weapon.
- the momentum assembly further comprises at least one interlocking cam to either engage a surface of the mounting ring when in a locked position, or to allow axial movement of the interlocking cam, and thus the momentum assembly, in reaction to the firing of the weapon.
- the one or more interlocking cams can be integral to the exterior surface of the momentum assembly or a region of it, or they can be a separate part of the assembly.
- the one or more interlocking cams can be adjusted from the position where it engages a surface of the assembly, such as a surface of the mounting ring on one end, to a position where the momentum assembly is axially displaceable upon firing without disconnecting the suppressor from the barrel.
- the adjustable suppressor can also include a momentum assembly that is formed with an octagonal exterior surface area, and with four interlocking cams provided on the octagonal exterior surface. These cams can engage an interior surface of the assembly, such as the mounting ring, to lock the momentum assembly. In one preferred embodiment, turning the mounting ring can lock or unlock the movement of the momentum assembly.
- an adjustable suppressor can include an index disk and mounting ring that can be locked to one another. Similar in function to other indexing systems available, where the position of the suppressor on the barrel can be rotated to adjust the aim of the weapon while the suppressor is attached, the index disk of the invention is within the momentum assembly. Thus, with the index ring of the invention, a component part of the suppressor can be rotated to adjust the aim of the firearm while the suppressor is attached to the barrel. Locking the index ring to the mounting ring will fix the desired adjustments.
- the adjustable suppressor according to the invention can have additional gas flow orifices or baffles formed into a region of the momentum assembly so that gasses can be adjusted to flow during either locked or unlocked positions.
- a cone region on the columnar sleeve end of the momentum assembly deflects gas into additional baffles formed into a reciprocating region of the momentum assembly.
- the additional orifices have longitudinal openings on the surface of the momentum assembly and can form a labyrinth seal within the suppressor.
- the momentum assembly can be locked by labyrinth seal to the interior of the suppressor to prevent its movement on firing. This advantageously reduces any noise.
- the additional baffles or orifices in the momentum assembly include rebounding surfaces or narrowing regions, or other gas flow conduits as known in the art.
- connection point-receiving point configurations One option is shown by looking at both of Figures 3 (reference number 8) and Figure 6 (reference number 20) together, which is a preferred option.
- four connection points can be arranged at a distance of 90° from one another and can be pressed into areas of the index disk having receiving points.
- This rotation can lock the four connection points into corresponding receiving points of the mounting ring, for example.
- the receiving points on the mounting rings are arranged at an angular distance of about 45° from one another.
- the angles selected and shown here are exemplary.
- the invention can also be a recoil booster device for use with a suppressor for a semiautomatic or fully automatic weapon.
- the device can comprise a momentum assembly that can be inserted or incorporated into a suppressor.
- the recoil booster itself need not be positionable into locked or unlocked positions with any suppressor selected. However, configurations allowing the facile switch from locking to unlocking positions are preferred Brief Description of the Drawings

- the silencer shown in Figure 1 consists of an outer column sleeve 1 , which is closed with a cover 2 in the front in the direction of shooting (exit point of the projectile).
- the column sleeve On the back the column sleeve has optional exterior notches 3 so that the mounting ring 4, which serves to mount the momentum part 5, can be screwed onto the corresponding outer thread of the column sleeve 1 with its inner thread, even under difficult conditions.
- the momentum part 5 has an inner thread with which the silencer/suppressor can be screwed onto the barrel of a firearm.
- mounting ring 4 has a side end surface 6 with a square opening 7.
- eight depressions 8 arranged at an angular distance of about 45° from one another can be seen, which serve for locking in the spheres that will be mentioned later.
- the guide part 9 (shown individually in Figure 5) is screwed in and this part is provided with circular guide surfaces 10 and recesses 11 and a thread 12 (Figure 5) for screwing it in, whereby the inner-facing surface 13 (toward the barrel) serves for supporting a spring mentioned below.
- a cone 14 ( Figure 5) provides for deflection of the gas from the impulse of firing and guides the gases through the recesses 11.
- longitudinal openings 15 ( Figure 4) are positioned in momentum part 5.
- Four interlocking cams 16 are positioned on the exterior, octagonal momentum part 5.
- the octagon surfaces can also be used for the placement of a wrench or tool to aid in dismounting if the momentum part is difficult to loosen.
- the index disk 18 of Figure 6 has provided on its periphery cams 19 for indexing the firing direction adjustment and fine tuning the aiming of the firearm toward the target.
- four spheres 20 are shown and can be pressed into the recessed depressions 8 ( Figure 3) for locking into the mounting ring 4.
- the index ring has four surfaces 21 that correspond to the exterior octagon shape of the momentum part 5.
- differing shapes can be chosen, and shapes that allow the locking of parts to the exterior of the momentum part are preferred.
- Figures 9, 10, and 11 show schematic, cross-sectional views of a suppressor in various operating modes, where it can be envisioned that the suppressor has a free channel in the middle along its entire length for the passage of the bullet.
- Figure 9 depicts the locked position.
- baffles or orifices 22 along the length of the suppressor reduce the velocity of the gases on firing and reduce the noise.
- the closure cover 2 is screwed onto the front, as noted above.
- a pressure spring 23 (shown in cross- section) is placed between the interior surface of column sleeve 1 and the momentum part 5, which butts against the inner surface 13 of the guide part 9 (as shown in Figure 5) on one end and against the index disk 18 ( Figure 6), whereby it presses the spheres 20 of the index disk 18 into the recesses 8 of the mounting ring 4.
- the interlocking cams 16 are thus blocked from moving by the mounting ring 4, as shown by the arrow in area A, where cam 16 prevents the movement of the momentum part 5.
- the momentum part does not move in reaction to the firing impulse and the firearm can be operated in a single-shot, silent mode, where cycling of the firearm is generally prevented.
- the mounting ring 4 is turned by 45° relative to the position in Figure 9, so that its surfaces no longer block the interlocking cams 16 from moving at area B.
- the momentum part moves in reaction to the firing impulse and delivers a counter-recoil force back toward the barrel, which allows the normal cycling of the firearm.
- the momentum part can be actuated to allow axial movement in reaction to the firing of the weapon by simply turning the mounting ring.
- Turning the mounting ring to the unlocked position can also free the interlocking cam from its blocked position to allow axial movement along the axis of the barrel of the weapon.
- the pressure spring 23 When a shot is fired while in the unlocked position, according to Figure 11 , the pressure spring 23 is first compressed by the recoil forces and then the momentum part 5 is pushed back.
- the momentum part 5 acts with the recesses 24 as a labyrinth seal and, together with cone 14 and the longitudinal openings 15, as additional orifices for the gas after firing.
- the momentum part or assembly can be present at a different area along the length of the suppressor than that shown in the figures here, but it is generally placed near the end that connects to the barrel of the weapon.
- the momentum part or assembly can be configured so that, while it is internal to the outer sleeve of the suppressor body, it does not permit movement of the suppressor body itself during firing.
- the spring component of the momentum part or assembly reacts to the forces upon firing, thereby applying a counter-acting force back toward the direction of the barrel.
- the distance H shown in Figure 11 does not represent the actual movement of the entire momentum part or assembly within the body of the suppressor during firing but is only the maximum distance the pressure spring 23 is able to compress in response to firing. Accordingly, at the moment of firing, one or more coaxial inner parts of a momentum assembly can move axially against a spring force to cause a recoil reaction and thus permit normal weapon function in automatic firing. Various extensions and other parts for connecting to the barrel of a weapon can be used to alter the placement of the momentum part or assembly within the body of a suppressor. Similarly, various rotational indexing systems as known in the art can be incorporated into the suppressors of the invention, and the example shown and described here is not the only design possible.
- Figure 12 shows the component parts of the momentum part or assembly, shown in previous figures, arranged as if they were about to be assembled.
- the mounting ring 4 may or may not be part of the assembly, but is shown in Figure 12 oriented as it fits with the momentum part or assembly for this embodiment.
- Figure 14 is a photograph showing a similar view of the component parts of the assembly as in Figure 12.
- Figure 13 is a photograph showing the momentum part fully assembled.
