Device for reducing recoil of firearm

Abstract

A recoil reducer device for use with a firearm is provided comprising a heavy weighted doughnut situated in a cylinder which is screwed onto the muzzle of the barrel. The exhaust gases as they exit the muzzle will enter the base of the cylinder through side portals and forcefully push the doughnut forward striking the base plate of the cylinder thereby pushing the recoil reducer device forward considerably reducing the recoil force generated by the fired bullet. A spring inside the cylinder will push back the weighted doughnut to its original position.

Claims

1. A recoil reducing device coupled to the front end of a firearm comprising: a hollow outer cylinder having a forward end and a rearward end, said rearward end configured to be coupled to a barrel of the firearm; a hollow inner cylinder situated within said outer cylinder having a forward end and a rearward end, said forward end having a circular plate to be coupled to the forward end of said outer cylinder; a weighted ring in a form of a doughnut situated in the space between the outer and the inner cylinder, and is slidably engage the outer periphery of said inner cylinder; a return spring for pushing said weighted ring rearward to its original position; and a resilient circular bumper firmly attached to the inside surface of the forward end of the circular plate of the inner cylinder as strike plate with the doughnut, wherein the body of said weighted doughnut is hollow and filled with heavy metal such as lead, bismuth, or mercury in order to increase its mass and make it heavy.

2. The recoil reducing device of claim 1 wherein the rearward end of said outer cylinder is internally threaded to allow coupling to said barrel; and said forward end of said outer cylinder is internally threaded to receive a circular plate of the inner tube wherein said circular plate having external threads.

3. The recoil reducing device of claim 1, wherein the inner cylinder further comprises a resilient rubber ring acting as a bumper to reduce the impact forces from the weighted doughnut as it is forcefully pushed forward by exhaust gases.

4. The recoil reducing device of claim 1, wherein the weighted doughnut's center provides a central hole for passage of the inner tube.

5. The recoil reducing device of claim 1, wherein the weighted doughnut is free to slidably move in the cylindrical space situated between the outer and the inner cylinder.

6. The recoil reducing device of claim 1, wherein the return spring is situated around the inner cylinder and is situated forward to the weighted doughnut.

7. The recoil reducing device of claim 1, wherein the rearward end of said inner cylinder further comprises an external snap ring to stop the weighted doughnut and prevent it from going back too far.

8. The recoil reducing device of claim 1, wherein the outer cylinder provides a plurality of gas exhaust orifices oriented outward allowing the exhaust gases to escape after pushing the weighted doughnut forward.

9. The recoil reducing device of claim 1, further comprising a central cylinder coupled at the forward end of said inner cylinder for restricting the amount of exhaust gases entering a compression chamber by causing the doughnut position to be adjusted in order to control the amount of gases entering the compression chamber of the recoil device.

10. The recoil reducing device of claim 9, wherein the central cylinder has a knurled end and coupled distally to the base plate of the inner cylinder allowing a shooter to reduce or increase the recoil by twisting said knurled end of central cylinder thereby restricting or increasing the volume of gases entering the compression chamber.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

(7) The recoil reducing device of this invention is intended to reduce the recoil force generated by the burning gun powder used for propelling the bullet through the barrel and out the muzzle. The device is easily screwed onto the muzzle of the barrel 6 via threads 25. The pressure in the combustion chamber can exceed 50,000 psi. As the bullet travels through barrel 6 and exit the muzzle 7 of the barrel, significant portion of the exhaust gases will be diverted to penetrate opening 12, situated in a circular fashion in front of muzzle 7. Said exhaust gazes will penetrate into the circular compression chamber 22 and push the circular weighted ring 1 forward toward the fore end of the rifle. Said circular ring having the shape of a doughnut made out of metal which has been rendered heavier by making it hollow and filling it up with lead, bismuth or even mercury. The circular weighted ring (doughnut) 1 will travel forward until it strikes a resilient circular rubber ring 14, which is firmly fixed against the base 13 of the distal end of the device FIG. 1. In doing so, the forward kinetic energy of the weighted ring 1 will be transferred to circular base 13. Said circular base 13 is screwed to outer cylinder 17 via threads 18 (FIG. 1). Holes 10 and 8 of appropriate size and number located in a circular fashion on the periphery of outer cylinder 17 will allow the exhaust gases from the compression chamber 24 to escape after pushing the circular weighted ring 1 forward until it strikes the circular rubber ring 14. Subsequently, springs 2 will push the circular weighted ring 1 backward to its initial position until it rests against circular stop 4. A circular stop ring 4 will prevent the movement of the weighted ring beyond the end of the inner cylinder (FIG. 1).

(8) In a different embodiment of the present invention, the volume of exhaust gases which enters the compression chamber 22 can be reduced thereby controlling the anti-recoil force. This is advantageous when using small calibers or lighter bullet. This is accomplished by having a central cylinder 19 threaded distally to endplate 9 via threads 23 (FIG. 2). Turning the knurled end 16 will move the cylinder 19 deeper thereby reducing the opening 15. Consequently, there will be less exhaust gases entering the chamber 22 transferring less kinetic energy to the weighted ring 1.

(9) It is clear that numerous variations may be made to the above described recoil reducing device without thereby departing from the principles of novelty inherent in the inventive idea. For example, the present disclosure's teachings may be used in rifles, shotguns or handguns.
