Abstract

A bullet suppressor for lowering the decibel level of a fired bullet from a firearm is disclosed. The effect of the suppressor is the trapping of exhaust gases trailing a bullet, such that the bullet exits the suppressor but the exhaust gases remain within the suppressor. This effect is achieved by the interaction of two levers within the suppressor, which are influenced every time a bullet is fired. As a bullet travels through the barrel of the suppressor, a first lever is forced to rotate in a first direction, causing a second lever to rotate in an opposite direction until it creates a boundary which traps exhaust gases exiting the firearm because they reach the end of the suppressor barrel. Other mechanical elements are also disclosed for more intricate systems within the suppressor. The trapping of the gases significantly reduces the sound of the gunshot.

Claims (20)

1. A bullet suppressor, comprising:

a pathway for a bullet,

a first lever, the first lever being rotatable about a first axis, the first lever having a top, a bottom, an outer end, and an inner end, wherein, in a first position, the outer end of the first lever extends into the pathway for a bullet such that a bullet travelling through the pathway contacts the outer end of the first lever causing the first lever to rotate in a first direction,

a second lever, the second lever being rotatable about a second axis, the second lever having a top, a bottom, an outer end, and an inner end, the second lever beginning in a first position,

wherein the inner end of the first lever is in mechanical communication with the outer end of the second lever, the second lever rotating in a second direction as the first lever rotates, said second direction being opposite to said first direction,

wherein the second lever rotates to a second position wherein its outer end becomes flush with a top of the pathway for said bullet, the second lever in the second position becoming a boundary, the boundary trapping exhaust gases exiting a firearm, the exhaust gases trailing the bullet, such that the exhaust gases remain in the suppressor as the bullet exits the suppressor, and

wherein the first lever and second lever thereafter return to the first position, thus delaying a release of the exhaust gases from the suppressor and causing a decrease in a decibel level of a gunshot.

2. The suppressor of claim 1 , further comprising:

a first spring, said first spring being compressible, said first spring being positioned under the bottom of the outer end of the first lever, said first spring continuously influencing the first lever to return to its first position.

3. The suppressor of claim 1 , further comprising:

said stopper, wherein the first lever's rotation in said first direction is stopped when the bottom of the outer end of the first lever contacts a stopper.

4. The suppressor of claim 2 , further comprising:

a spring-loaded lock for locking the first and second levers in the second position, thus maintaining the exhaust gases within the suppressor.

5. The suppressor of claim 4 , wherein the spring-loaded lock is connected to a fixing member.

6. The suppressor of claim 4 , wherein the spring-loaded lock becomes lodged in a crevice, the crevice being located on the inner end of the second lever, the crevice becoming accessible to the spring-loaded lock when the second lever rotates to the second position.

7. The suppressor of claim 6 , wherein a recoil and a return of a gun slide of a firearm causes a dislodging of the spring-loaded lock from the crevice, the dislodging causing the first lever and second levers to return to the first position.

8. The suppressor of claim 6 , further comprising:

a turning member connected to a sliding member, the turning member being influenced by the sliding member to rotate thus forcing the spring-loaded lock to dislodge from the crevice, the sliding member being influenced by a movement of a gun slide of a firearm.

9. The suppressor of claim 8 , further comprising:

a spring member further connected to the sliding member, wherein the spring member is in contact with the gun slide of said firearm.
