SPECIFICATION forming part of Letters Patent No. 743,042, dated November 3, 1903. Application filed May 9, 1902. Serial No. 106,633. (No model.)

To all whom it may concern.". 1

Be it known that I, WILLIAM SPEIRs SIMP- SON, a subject of the- King of Great Britain, residing at 49 Battersea Park road, London,

5 England, have invented certain new and useful Improvements in Recoil-Minimizers for Firearms, of which the following is a specification.

The object of this invention is-to apply a o shield to the muzzle end of ordnance and small-arms in such a manner that the gases as they leave the muzzle have full action upon the shield and efiectually minimize recoil of the weapon. To effect this object to the maxi- 5 mum extent, I find that the best form ofshield or hood is a hollow hemisphere shortened so that the projectile may still be blocking the exit-hole while the gas is first escaping to the rear, so that no gases can escape without hav- 6 ing their full action upon the shield, and to assist this action the rirn'of the shield should be in the same plane as the face of the muzzle. A minor elfect of this arrangement is to slightly augment the velocity of the project- The shield is provided with ahole in axial. line with the barrel and is of the same or slightly-larger diameter as the bore of the barrel, and through this hole the bullet passes while leaving and after having left the barrel, so that said hole is closed while the gases are exerting their greatest and working influence upon the shield to, so to speak, push the gun forward, this action efiectually overcoming the recoil, andthus preventing same.

The shield for the purpose of attachment may be provided on its inside with four webs,which project and encircle the barrel to which they are brazed to fix the shield in proper position, and such shield may be provided with an extra hole through which the sighting is eifected or be provided itself with a sight-notch. The shield may be of semispherical or conical or conoidal formation and in the case of military small-arms may be provided with a stub,

on the barrel the bayonet may be secured when usedfor military purposes. The shield may be used for either single or double bar reled guns or for pairs of heavy guns.

to which and also to the bayonet-fixing piece The annexed drawings show my construction of shield.

Figure 1 is an elevation of a shield looking inside, the sight-notch being on top and forming part of the webs. Fig. 2 isa side section of Fig. 1 and showing its application to a gunbarrel. Fig. 3 is a front elevation of the shield shown in Fig. 2. Fig. 4 is a front elevation of a shield with the webs in dotted lines, the shield having an extra hole through which the sighting is efiected. Figs. 5 and 6 are front elevation and side section of a con ical-shaped shield. Fig. 7 is a rear elevation of a shield for a double-barreled gun. shows the application of my shield to a smallarm, and Fig. 9 to a cannon. Fig. 10 is an elevation of the muzzle end of a rifle having my shield applied, said shield being provided with a stub and with the rifle carrying a bayonet.

1 is the shield form, semispherical at Figs. 1, 2, 3, 4;, 7, 8, and 9, but conical at Figs. 5 and 6. This shield 1 is provided with a hole 2, through which the bullet passes, and has secured by riveting, brazing, or otherwise on its inside webs or flanges '3, these projecting beyond the edge line of the shield 1 for attachment to the muzzle 4 of the gun 5 by brazing or otherwise. According to Figs. 1, 2, 3, 5, 6, 7, 8, and 9 the foresight 5 is made from one of the webs 3; but with the construction shown in Figs. 4 and 10, wherein a. sighting-hole 6 is made, the ordinary foresight 7 is used on the barrel. Thus it will be seen that by this invention all the efiective power of the gases is employed to prevent recoil by reason of such gases meeting with a solid resistance as they leave the barrel, the bullet then filling the hole and the edge of the shield being in a line with the end of the muzzle of the gun, so-that no gases can escape until their initial power is exhausted.

What I claim, and desire to secure by Letters Patent, is- Y 1. A recoil-minimizer for firearms consisting of a rearwardly-projecting shield having its edge in the same plane with the end of the muzzle of the firearm and provided with an opening for the passage of the bullet, and

webs secured to the inner face of the shield .and projecting therefrom, said Webs adapted to extend upon and to be secured tothe barrel of the firearm for connecting the shield thereto. Y s

2. A recoil-minimizer for firearms consisting of a rearwardly-projecting shield having its edge in the same plane with the end of the muzzle of the firearm and provided with an opening for the passage of the bullet, said shield further provided at a point a suitable distance from its edge with an opening for sighting, and webs secured. to th inner face of the shield and projecting ther from, said webs adapted to extend upon and to be secured to the barrel of the firearm for connecting the shield thereto.

3. A recoil-minimizer for firearms consisting of a concaved shield having its edge in the same plane with the end of the muzzle of" the firearm and provided with an opening for the passage of the bullet, and webs secured to the inner face of the shield and projecting provided at a point a suitable distance from its edge with an opening for sighting, and webs secured to'the inner face of the shield and projecting therefrom, said webs adapted to extend upon and to be secured to the barrel of the firearm for connecting the shield thereto. y

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
