Title:
Firearms recoil reducer
Kind Code:
A1


Abstract:
The present invention relates to firearms recoil reducer. Current reducers are some type of shock absorbers with limited efficiency, of about 15%. The lift and the back kick of the firearm remain causing pain to the shoulder and instability in targeting especially with repeating firearms. In my invention the combined recoil of primary recoil associated with bullet speed and about four folds more powerful secondary recoil associated with exploding gas burst leaving the front of the barrel are countered by the backwards puff of the burst by the recoil reducer. The secondary recoil resulting from exploding gas burst leaving the barrel is utilized to nullify the primary and part of the secondary recoil. My recoil reducer is a wide cap absorbing the explosion and pulling forward the muzzle to counter the native recoil. The recoil reduction is further maximized or reinforced by a duckbill valve, by wide flat cap, by flat cap with side walls or rims, and by a cup shaped reducer with a hole in its bottom part. The force of recoil is adjustable by the space between muzzle and reducer. The recoil reducer can be multiple backward slanted holes or grooves with a collar around the muzzle to guide the explosion gas burst backwards to counter the original combined recoil.

Description:

TECHNICAL FIELD

The present invention relates to reduce firearms recoil. Rifles, pistols, shotguns, & cannons upon firing give a back recoil and uplift of the projectile. The backward recoil of a rifle or a pistol cause a delay in repeating a second or third shot at target or at attacking enemy. Recoil makes it inconvenient and painful to the shoulder of the shooter. Similarly with a hand gun the projectile uplift and the backward kick back makes training or shooting at enemy less efficient. Also during training, the shooter is more accurate when the recoil factor is reduced or eliminated. The same drawback applies to cannon, the recoil of a cannon hinders speed of firing and accurate targeting. The powerful recoil of a cannon can overturn a jeep if it is mounted on it. For faster maneuverability or for mountain or urban fighting cannons can be mounted on a jeep instead of a tank.

BACKGROUND ART

At present all recoil reducers are some type of shock absorber that reduces the recoil no more than 15%. Recoil reducers vary in type from rubber padding on rifle butt, steel balls in mercury tubes, or plain heavy weight at the end of muzzle of a pistol.

DISCLOSURE OF THE INVENYION

The present invention relates to eliminating the recoil by a front blocker-reverser of the expanding explosion burst leaving the front end of the barrel. The primary recoil is caused by accelerating the projectile along the barrel. But the estimated four times more powerful recoil is the secondary recoil caused by the expanding exploded gas burst. Firing a shotgun blank with felt or cloth packing instead of metal projectiles gives a recoil the shooter can not differentiate from shooting a regular shell. With my recoil reducer consisting of a cup like metal with a big hole in the base of the cup make the exploded gas burst turn into a strong backwards buff that counterbalance the standard recoil. At landing, a jet engine uses an equivalent arrangement, the air brakes, to slow down the plane on ground.

DETAILED DESCRIPTION OF THE DRAWINGS

FIG. 1. The recoil in a pistol 20 is in backward direction 21 and uplift of the muzzle 22. The backward recoil of a fired weapon lift the muzzle up and pushes the muzzle backwards.

FIG. 2. Recoil reducer cap is fitted to the front end of the barrel 22 in front of the muzzle. My recoil reducer is fitted to the front end of the muzzle to reduce the resulting lift and the resulting kickback. At firing, the expanding gas burst pushes the reducer forwards and the reducers pulls the muzzle forward with it.

FIG. 3. Reducer cap 23 is filled with exploding pressurized gas burst in front of the barrel. With this forward push the reducer pulls the barrel forward through its connection 24 to the muzzle thus countering the primary kickback. The barrel is in line with an opening or central hole in the reducer cap to let the projectile fly into its trajectory.

FIG. 4. Shows bullet 25, continues in its trajectory with primary recoil force 40. The recoil force 40 is counter balanced by the force of exploded gas burst pushing the cap forwards by force 41 which in turn pulls the muzzle forwards through connection 24 fastened to the muzzle on one side and to the reducer on the other side. Bracket 43 is tightened by screw 44 to counter the backwards recoil. Air puff 42 will be backwards in direction and its force being proportional to the secondary recoil of the burst of the expanding explosion and inversely proportional to the distance of the reducer from the mouth of the barrel. The shape of the reducer will effect the efficiency of the reducer to become smaller or bigger than the recoil generation by the speed and direction of the projectile, the primary recoil force, the third Law of Newton in Physics. The secondary recoil caused by the expanding burst of exploded gas near the end of the barrel can be bigger than the primary recoil. Adjustment of distance from the barrel can nullify the primary recoil to zero force o produce a negative recoil or forward pull.

FIG. 8. Vertical cross section of the recoil cap of FIG. 4 at position D. showing cap wall 32 and central hole 31

FIG. 9. Vertical cross section of FIG. 4 at position E showing outer wall 33 and trajectory 34.

FIG. 10. Reducer cap with reverse compression space 23 producing a back puff 46. Projectile 25 continues in its trajectory path. FIG. 11. A more powerful reducer cap with its duck bill valve 35 and 36 closed to increase compression puff backwards by blocking the burst leak through the central hole in the reducer.

FIG. 12. The more powerful reducer cap with its opened duck bill valve 37 and 38. The side of the moving bullet 25 press against valve lip 66 to close valve fore more powerful recoil reduction. Valve also is closed by the pressure of the burst on valve external surface.

FIG. 13. Flat cap reducer 41 with center hole 42. The backward puff 46 causes reduction in the back recoil.

FIG. 14. Cup shape reducer cap with around muzzle surrounding wall 43 and base 44. The base has a hole 45.to allow the projectile to go through. towards target. Backward burst puff 47 pulls muzzle forwards reducing the recoil.

FIG. 15. Flat base reducer cap with 4 outsides walls 48, 49, and 50 guides the gas burst to go backward and to counter balance the backwards primary recoil.

FIG. 16. Shows recoil reducer as backwards slanted holes 53 and 54 in muzzle wall 23 near the barrel front-end opening 23 causing a backward burst or gas jet in direction 60. Jet 60 counter the primary recoil and also counters part of the secondary recoil caused by the burst of the exploding gas 64.

FIG. 17. Shows vertical holes 55 in muzzle wall and the surrounding cap 56 around the muzzle 23 guiding part of the exploding gas burst to push backwards in direction 61 causing the muzzle to be pulled forwards. This action counters the recoil resulting from the gas 64 exploding forwards from the barrel opening and counters the primary recoil of the projectile.

FIG. 18. Shows muzzle 23 with slanted holes 57 and backward slanted groove 58 reaching the inside of barrel where burst of exploded gas expands in backward direction 62 countering recoil explosion 64.
