Title: Novel modular sound suppressing device for firearms

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation-in-part (and claims the benefit of priority under 35 USC 120) of U.S. application No. 63/123,551 filed Dec. 10, 2020. The disclosure of the prior applications is considered part of (and is incorporated by reference in) the disclosure of this application. 
    
    
     BACKGROUND 
     The present invention relates to a novel sound suppression device, and more particularly to reducing the acoustic intensity of the muzzle report. 
     Most suppressors/silencers are attached to the muzzle of a firearm and use a series of baffles inside a tubular outer shell to achieve reduced muzzle sound and flash. These designs attempt to use the baffles as a means to slow and allow to cool the hot discharge gasses and combustion products produced by the burning of propellants used in modern firearm cartridges. These gasses and combustion products leave the muzzle of a firearm at super-sonic speeds creating a shock wave and Mach disk that is the is the source of the loud report associated with firearm discharge. Unburned and partially burned propellants also exit the muzzle creating a flash of bright light that can be undesirable. The performance of this type of suppressor/silencer is only moderately successful, there still exists a high decibel sound and sometimes a flash still associated with this type of device. The use of baffles of many types (Q, S, P, OMNI) to name a few, are only partially successful in the reduction in sound and flash. Asymmetrical baffles can be more effective in the reduction of noise but have the undesirable effect of causing deviation in the path of the projectile leading to poor ballistic performance of the fired bullet. 
     Most silencers are caliber specific, meaning a separate Tax Stamp and silencer must be purchased for each caliber. 
     Most suppressors/silencers are attached to the muzzle of a firearm and use a series of baffles inside a tubular outer shell to achieve reduced muzzle sound and flash. These designs attempt to use baffles as a means to slow and allow to cool the hot discharge gasses and combustion products produced by the burning of propellants used in modern firearm cartridges. These gasses and combustion products leave the muzzle of a firearm at super-sonic speeds creating a shock wave and Mach disk that is the is the source of the loud report associated with firearm discharge. Unburned and partially burned propellants also exit the muzzle creating a flash of bright light that can be undesirable. 
     The performance of this type of suppressor/silencer is only moderately successful, there still exists a high decibel sound and sometimes a flash still associated with this type of device. The use of different types of baffles are only partially successful in the reduction in sound and flash. 
     Alternatively, asymmetrical baffles can be more effective in the reduction of noise but have the undesirable effect of causing deviation in the path of the projectile leading to poor ballistic performance of the fired bullet. 
     Therefore, a new design of firearm suppression is desired that further reduces the sound and flash than the previous devices.

The advantage of the present invention is it is much quieter. It does not require hearing protection when using a firearm. According to Occupational Safety and Health Administration (OSHA) guidelines sound above 140 decibel (dB) is injurious to hearing. this device greatly reduces the dB levels allowing a shooter to no longer need hearing protection to avoid hearing damage the invention can be used with various firearms from handguns to rifles. The ability to use this device on multiple calibers of firearm greatly reduces the costs associated with suppressing multiple firearms. This provides an improved silencer/suppressor for numerous firearms. 
     The advantage of the invention is its quietness, superior flash suppression and the ability to use this suppressor on multiple calibers compared to other designs. Other suppressor designs are based on the use of various types of baffles, this has not changed in over 100 years. this new suppressor design does away with the baffles and achieves a superior effect with the use of the central passage, with apertures or ports to slow and cool gasses and other products of a modern firearm cartridge, therefore sound and flash reduction are greatly improved. 
     The suppressor is designed to work with a variety of different firearms of various calibers, there are currently on the market so called multi caliber suppressors, they are, in general, suppressors with a large enough central passage to accommodate the largest caliber they are rated for. This approach has a poor reduction of sound and flash with smaller calibers, due to the large central passage. This novel design addresses this shortcoming by having three interior parts that can easily be replaced. The diffuser disc, the upstream diffuser tube, and the end disc are supplied with this system in three different diameters of the central passage to more closely match the caliber being fired, thus achieving better sound and flash reduction. The ability of this design to be used on multiple calibers of firearm greatly reduces the costs associated with suppressing the many calibers of firearms owned by many shooters. 
     The advantage of the invention is its quietness, superior flash suppression, and the ability to work with a variety of calibers. Other suppressor designs are based on the use of various types of baffles, this has not changed in over 100 years. this new suppressor design does away with the baffles and achieves a superior effect with the use of the central passage, with holes or ports and the screen or ribbon to slow and cool gasses and other products of a modern firearm cartridge, therefore sound and flash reduction are greatly improved over previous designs.

     For the purpose of clarity, the following descriptions are used. Upstream shall be understood to indicate the direction from which a projectile comes from. Downstream shall be understood to indicate the opposite direction. 
     The present disclosure is to be considered as an exemplification of the invention and is not intended to limit the invention to the specific embodiments of the figures or description below. 
     The Figures depict various images of the suppressor  100 , in accordance with one embodiment of the present invention. The suppressor  100  is comprised of a barrel mount  200 , a tube  400 , a retaining ring  700 , a diffuser disc  300 , an end disc  800 , a diffuser core assembly (comprised of an upstream diffuser tube  600  and a downstream diffuser tube  500 ). The suppressor  100  components are able to be separated into its components for cleaning and for ease of replacement of parts. 
     Barrel mount  200  attaches to the muzzle of a firearm by means of the threaded opening  201 . In additional embodiments the threaded opening  201  may be replaced by other means to secure the suppressor  100  to the fireman based on the type of firearm. At the opposite end of the barrel mount  200  is a threaded portion  202  which is used to secure the barrel mount  200  to the tube  400 . The tube  400  has a first end with a threaded female opening  401  and a second end with a threaded male  402  extension. The opening  401  is designed to mate with the threaded portion  202  of the barrel mount  200 , and the threaded extension  402  is designed to mate with the opening  702  of the retaining ring  700 . The tube  400  has a top end  403  which is designed to fit the diffuser disc  300  in place and an extended middle portion  404  to fit the diffuser core assembly. The retaining ring  700  is designed to secure to the threaded extension  402  of the tube  400  and has an opening  705  for the projectile to exit the suppressor  100 . These three parts form the exterior body of the suppressor  100 . 
     The suppressor is connected to the firearm at the barrel mount  200 , showing the (upstream) end which attaches to the muzzle of a firearm by threads or other means. The barrel mount  200  has a threaded opening  201 , that can be used to attach the suppressor to the muzzle of a firearm. Also visible are the two apertures  204 , in the outer edge of the barrel mount  200 , that are to be used with a spanner type wrench to firmly assemble the suppressor. The (upstream) end or edge of the barrel mount  200 , is beveled  203  to relieve a sharp edge. Internally the barrel mount  200  has a cavity  205 . At an opposite end of the threaded opening  201  is a portion of the barrel mount  200  which is threaded  202 . The barrel mount  200 , is formed with an opening  201  with threads at the (upstream) end of the part, in the center, to attach to the muzzle of a firearm. The barrel mount  200  is formed with threads  202  at the (downstream), outside, end to attach to a threaded end  401  of the tube  400 . 
     Contained within the exterior body of the suppressor  100  is the diffuser disc  300 , the end disc  800 , a diffuser core assembly (comprised of an upstream diffuser tube  600  and a downstream diffuser tube  500 ). The diffuser disc  300  is secured between the barrel mount  200  and the tube  400 . The diffuser core assembly comprises a downstream diffuser tube  500 , an upstream diffuser tube  600 . The downstream diffuser tube  500  is secured to the upstream diffuser tube  600  at one end and is secured to the end disc  800  at the other one end. The upstream diffuser tube  600  is inserted into a groove  310  of the diffuser disc  300  at the end which is not secured to the downstream diffuser tube  500 . The diffuser disc  300  is secured between the tube  400  and the barrel mount  200 . The downstream diffuser tube  500  is secured to the end disc  800 . When fully assembled a substantially straight channel is formed from the barrel mount  200  to the retaining ring  700  so a projectile is able to enter and exit the suppressor  100  without coming in contact with any part of the suppressor  100  and with minimal effect on the rotation, speed, and trajectory of the projectile. Within the tube and the barrel mount  200  are space which is designed for the gasses and high energy by products of the projectile to expand into. 
     Barrel mount  200  has a lip  203  along the threaded end which is designed to receive the diffuser disc  300  and secures the diffuser disc  300  in place between the barrel mount  200  and the tube  400 . The diffuser disc  300  has a plurality of apertures  301  to allow for the passage of gases and by products of the cartridge. The aperture  301  has a counter sink  306  design on both sides of the diffuser disc  300 . A central aperture  305  is designed to allow passage of the projectile. The diffuser disc  300  has an upper portion  303  and a lower portion  304  where a surface  302  is formed which comes in contact with the lip  203  of the barrel mount  200 . 
     The downstream diffuser tube  500  is a perforated tube that allow gasses and other high energy products of the combustion of the propellant in the cartridge to be directed into the cavity  105  of the tube  400 . The apertures  502  are of a predetermined size, positioning, and pattern. These expanded and cooled gasses and other high energy products of the combustion of the projectile, meet the gasses that flowed through the apertures. The downstream diffuser tube  500  has a threaded end  503  which connects with a threaded opening  603  of the upstream diffuser tube  600 . The opposing end of the downstream diffuser tube  500  is treaded  504  to connect with the end disc  800 . 
     The upstream diffuser tube  600  is a perforated tube that allow gasses and other high energy products of the combustion of the propellant in the projectile to be directed into the space formed between the upstream diffuser tube  600  and the tube  400  and allows the projectile to exit the suppressor  100 . The apertures  602  are of a predetermined size, positioning, and pattern. The upstream diffuser tube  600  has a threaded end  603  which connects with a threaded opening of the downstream diffuser tube  503  and has a smooth end  605  which fits within the groove  310  of the diffuser disc  300 . 
     The end disc  800  has a threaded opening  804  designed to receive the downstream diffuser tube  504 . The end disc  800  has a central opening  805 . The end disc  800  has an upper portion  801  and a lower portion  803  which form a lip  802 . The upper portion  801  and the lower portion  803  are sized differently to create the lip  802  which is used to secure the diffuser disc  800  between the retaining ring  700  and the tube  400   
     The retaining ring  700  has a central opening  705  and a threaded portion  701  to secure to the tube  400 . 
     The gasses and other high energy products are forced to slow and cool as they expand and pass from the muzzle of the firearm into the chambers, which are formed inside the suppressor  100 . These chambers are designed so that gasses flow from the inner channel into the space within the suppressor  100 . 
     The gasses and other high energy products are forced to slow and cool as they expand and pass into the chamber formed inside the second section. 
     The barrel mount  200  and the tube  400  are secured together, with the diffuser disc  300  compressed between these two elements. The barrel mount  200  and the diffuser disc  300  have substantially similar profiles, so that the two parts securely come in contact with one another along their edges. When the diffuser disc  300  is positioned within the tube  400  and the barrel mount  200  is secured to the tube, the diffuser disc  300  securely fits between the barrel mount and the tube so that there is little to no movement of the diffuser disc  300 . This forms cavity  205  within the barrel mount  200 . The cavity,  205 , which is formed by the walls of the barrel mount  200  and terminated by the diffuser disc  300 , where the gasses and other high energy products generated by a particular cartridge used by the firearm exit the muzzle of the firearm. These gasses and other high energy products exit the muzzle of a firearm at super-sonic speeds, at high pressure and high temperature. This cavity  205  inside the barrel mount  200  of the suppressor allows the gasses and other high energy products generated by a particular cartridge used by the firearm to slow and cool as they enter this cavity by allowing expansion into the cavity,  205 . 
     The gases that exit cavity  205 , exit through openings  301  or aperture  305  of the diffuser disc  300 . The diffuser disc  300  is formed so that at its center an aperture  305  is formed, that allows the passage of the fired projectile. Both the (upstream) and (downstream) edges  306  of this aperture  305  are beveled, to avoid disturbing the path of the projectile. In some embodiments, the aperture  305  is not beveled or has one side which is beveled. The diffuser disc  300  has a groove  310  with a predetermined depth and width, and openings  301  which extend completely through the diffuser disc  300 . These cooled and slowed gasses and other high energy products exit the cavity  205  through the central aperture in the diffuser disc  300 , and through a plurality of openings  301 . Formed in a circular fashion in the diffuser disc  300 , these openings  301  allow portions of gasses and other high energy products produced by a modern cartridge that do not go through the central aperture in the disc, to slow and cool further as they enter the space  105  inside the tube  400  of the exterior of the suppressor. Passing through these openings  301 , slows and cools these gasses and other high energy products. This disc is formed with a “stepped” edge, this allows the smaller diameter to fit the open end of the barrel mount  200 . The inside of the barrel mount  200  is formed to accept the diffuser disc  300 . 
     The upstream diffuser tube  600  is sized to fit within the groove  310  of the diffuser disc  300  to secure the upstream diffuser tube  600  in place. The majority of the upstream diffuser tube  600  has a series of openings  602 . The portion of gasses and other high energy products exit the chamber  205  formed in the barrel mount  200 , and the other portion of gasses and other high energy products exiting through the plurality of apertures  602  formed in the upstream diffuser tube  600 . The internal diameter and external diameter of the upstream diffuser tube  600  are larger than that of the downstream diffuser tube  500  to create a larger space (but smaller than cavity  205 ) for the gases to expand behind the projectile. The thickness of the upstream and downstream diffuser tubes is based on the material strength to be able to handle the forces exerted on them and to withstand the heat produced by the ignition of the cartridge. The downstream and upstream diffuser tubes, have a predetermined wall thickness and are robust enough in construction to contain the initial ejection of gasses and other products produced by the firing of a modern firearms cartridge. 
     The downstream diffuser tube  500  is a hollow tube. The openings  502  may be substantially the same diameter as shown in the depicted embodiment. In additional embodiments, the openings  502  may be of various diameters and formed in different angles. The openings  502 , allow the energetic products of cartridge ignition to flow into and out of the interior cavity of the downstream diffuser tube  500 . The outflow of these gases and other high energy products of cartridge ignition is facilitated by the constriction of the central passage at the end disc  800 . The gasses and other high energy products produced by the ignition of the cartridge are slowed and cooled by their passage through the openings  502 . The openings  502  are positioned in a predetermined way to maximize the number of openings while also providing enough structural rigidity. 
     A large portion of gasses and other high energy products exit through the plurality of apertures  502  and  602  into the interior space  105 . In the depicted embodiments, the openings  602  and  502  are positioned in rows and of substantially similar diameters. In various embodiments the positioning of the openings  502  and  602  may be adjusted and the size of the openings  502  and  602  may be adjusted. In additional embodiments, the openings  502  and  602 , may be in an alternating pattern or alternating sizes and angles. 
     The upstream diffuser tube  600  is designed to mate with the downstream diffuser tube  500  and be inserted into the diffuser disc  300  groove  310  so that all interior parts align within the suppressor. The upstream diffuser tube  600  is inserted into the groove  310  of the diffuser disc  300 . The silencer  100  is designed so it can be easily assembled and disassembled and have parts replaced when necessary. The upstream diffuser tube  600  has a plurality of apertures  602  displaced along the tube, but with proper distancing from the threaded end and the open end. Gasses and other high energy products which pass through the upstream diffuser tube  600  are further expelled through these apertures  602 . A large portion of gasses and other high energy products exiting through the plurality of apertures  602  of the upstream diffuser tube  600 . The apertures  602  are sized, angled, and positioned, based on the quantity of gasses and high energy products which are created when a bullet is fired. The upstream diffuser tubes  600  has a predetermined diameter, length, apertures sizes, and the like. The upstream diffuser tube  600 , has a tubular structure. The portion of gasses and other high energy products that exit the upstream diffuser tube  600 , through the apertures  602  will enter the interior cavity  105  where they continue to cool and expand. 
     The downstream diffuser tube  500  is designed to mate with the upstream diffuser tube  600  and mates with the end disc  800  so that all interior parts align within the suppressor. The downstream diffuser tube  500  has a plurality of apertures  502 . These apertures  502  are positioned to not interfere with the threaded ends. Gasses and other high energy products which pass through the downstream diffuser tube  500  are further expelled through these apertures  502 . A large portion of gasses and other high energy products exiting through the plurality of apertures  502  along the side of the downstream diffuser tube  500 . The apertures  502  are sized, angled, and positioned, based on a quantity of gasses and high energy products which are created when a bullet is fired. The downstream diffuser tube  500  has a predetermined diameter, length, apertures sizes, and the like. The downstream diffuser tube  500 , has a tubular structure. The portion of gasses and other high energy products that exit the downstream diffuser tube  500 , through the apertures  502  will enter the interior cavity  105  where they continue to cool and expand. The downstream diffuser tube  500  is of a smaller interior and exterior diameter than the upstream diffusor tube  600  allowing a larger space to be enclosed by the tube  400  promoting the further expansion and cooling of the gasses and other high energy products produced by the ignition of a modern cartridge. In some embodiments, the diameter of the upstream diffuser tube  600  and the downstream diffuser tube  500  are proportionate based on the weapon and the caliber. In the depicted embodiment the upstream diffuser tube  600  has a larger interior diameter than the downstream diffuser tube  500 . In other embodiments, the diameters may be the same, or the downstream diffuser tube  500  may be larger than the upstream diffuser tube  600 . 
     The gasses and other high energy products produced by the ignition of the cartridge are slowed and cooled by their passage through the openings, apertures or ports  602  and  502 . The openings  602  and  502 , are positioned in a predetermined way to maximize the number of openings while also providing enough structural rigidity. In the depicted embodiment, the openings  602  and  502 , are positioned in substantially straight rows and columns. In some embodiments, these openings  602  and  502  are formed at a 45-degree angle towards the (downstream) end of the suppressor to direct the gases into the cavity  105 . In additional embodiments, the openings  602  and  502 , may be in various patterns, sizes (diameters), shapes, angles, and the like. In some embodiments, the openings  602  and  502  each opening can be a different size. 
     The retaining ring  700  holds the end disc  800 , inside the (downstream) end of the tube  400  of the suppressor. The retaining ring  700  has a threaded interior surface  701 , and an opening  702 . The end disc  800  “stepped” portion  803  is compressed between the retaining ring  700  “shoulder” and the tube  400 . When the tube  400  is secured to the retaining ring, the end disc  800  is secured in place and assists in aligning the upstream and downstream diffuser tubes  500  and  600 . The end disc  800  has a threaded opening  804 . The end disc  800  attaches to the downstream diffuser  500  and are aligned in the center of the suppressor. 
     In some embodiments, opening  805  of the end disc  800  is beveled to relieve the sharp edge. 
     The end cap  700  has a plurality of openings for use with a spanner type wrench to be used to tighten the threads of the assembly. 
     When constructed, the upstream and downstream diffuser tubes  500  and  600  are secured within the tube  400 , and between the end disc  800  and the diffuser disc  300  respectively. The tube  400  and the retaining ring  700  secure the end disc  800  and the upstream end of the upstream diffuser tube  600  is firmly secured in the groove  310  of the diffuser disc  300 . With the components assembled an interior cavity  105  is formed. 
     The interior cavity  105  which is formed within the tube  400 , provides an increased volume for the gasses to expand before needing to exit the suppressor. The upstream diffuser tube  600  is of a larger interior and exterior diameter than the downstream diffuser tube  500  tube allowing for more expansion and cooling of the gasses and other high energy products produced by the ignition of a modern cartridge. 
     The tube  400  extends from the barrel mount  200  to the retaining ring  700 , at the outer (downstream) end of the suppressor and forms cavity  105 . These three parts are joined in a linear fashion by having mating threaded portions on the parts. For example, the male threads formed on the (downstream) end of the barrel mount  200 , mating with the female threads formed on the inside (upstream) end of the tube  400  and the (downstream) male threads formed on the outside of the tube  400 , mating with the female threads formed on the inside of the retaining ring  700 . 
     The end disc  800  is secured between the retaining ring  700  and the tube  400  when they are secured together. The (downstream) end of the tube  400  is terminated in this assembly by the end disc  800 , the first “stepped” portion of this disc fits inside the circular opening formed to accept this “stepped” portion of the end disc  800  in the (downstream) end of the tube  400 . The second “step” matches the diameter of the threaded (downstream) end of the tube  400 . This allows the end disc  800  to be held firmly in place between the retaining ring  700  and the tube  400   
     At the (downstream) end of the diffuser disc  300 , the interior diameter of the tube  400 , a “shoulder”, is formed with a smaller diameter then the diameter of the larger stepped portion of diffuser disc  300 . When the (upstream) female threads on the tube  400  and the (downstream) male threads on the barrel mount  200  are tightened, the diffuser disc  300  is compressed. This, along with the tightening of the tube  400  and the barrel mount  200 , forces the alignment of the diffuser disc  300 , providing a straight and clear path for the projectile to pass through all parts of the suppressor without striking any portion of this assembly. 
     The cavity  105  formed within the tube  400  between the interior surface of the tube  400  and the exterior surfaces of the upstream and downstream diffuser tubes  600  and  700 . This cavity  105  provides for space for the gasses and other high energy products of the ignition of a modern cartridge from inside the central diffuser tube and the portion that passed through the plurality of apertures in the diffuser disc  300 , mix, combine and interfere with each other. This allows the gasses and other high energy products to further slow and cool. The gasses and other high energy products then exit through the openings  602  and  502  and finally exit the suppressor through the opening  805  in the end disc  800 . 
     The suppressor  100  is designed to work with a variety of firearms with a variety of different calibers. The threaded opening  201  of the barrel mount  200  is able to be various sizes and designs to accommodate different firearms and different calibers. The upstream and downstream diffuser tubes  500  and  600  may also have varying interior diameters and lengths to accommodate different calibers, as well as the diffuser disc  300 , end disc  800 , or the retaining ring  700 . The tube  400  may be of varying sizes and diameters based on the firearm and different calibers to be able to accommodate the energy, heat, gases, and the like which are produced by the different cartridge sizes. The key advantage of this design is the ability to design each component for various firearms and calibers and allow the user to replace specific components when changing between firearms and calibers and not have to purchase an entirely new suppressor. They can just replace the specific component that needs to be changed out. For example, the barrel mount  200  can be swapped to be used on two different firearms with the same caliber but have different barrels. One barrel may be metric, and the other barrel may be UNC/UNF but have the same or comparable calibers. In some embodiments, the barrel mount  200  may have an additional adapter or the like made to attached to the threaded end of the barrel mount  200  so that the suppressor can be used with various firearms without having to replace the barrel mount  200 . 
     The threaded portions of the components may have various tread counts and types. Including but not limited to unified national coarse (UNC), metric, or other types known to someone skilled in the arts. 
     While this invention has been described in conjunction with the specific embodiments outlined above, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the preferred embodiments of the invention, as set forth above, are intended to be illustrative, not limiting. Various changes may be made without departing from the spirit and scope of this invention.
