(GBA-MED UNDER THE ACT 40F MARCH 3, 1883; v22 STAT. I.. 625:)

. To all 'whom it. may'comem:

Be it known that I, JOHN B.- Rosn, a cit-izen of the United States, and a resident of Warrenton, countyof Fauquier, and State 5 lof Virginia have invented an Improvement in Muzzle rakes, of which the following is a specification.

The invention .described herein lmay be used by the Government, or any of its oflicers or employees in prosecution of work for the Government, or by any other person in the United States, without paymentto me of any ro alty thereon, in accordance with the act of arch 3,1883. .Y My invention relates, in general terms, to muzzlebrakes for guns, which are designed to check 'the energy of recoil by utilizing the gases generated 'upon dischargeof the piece. More particularly my invention resides in the provision of means for dissipating the gases in any desired direction.

To attain the maximum edect, devices of this character have been so constructed that the full force of the gases' are diverted against the brake in such a manner that the yforce of resistance will be exerted as nearly parallel as possible to the\direction of recoil. Consequently, the released gases will be -projected along the line of recoil and will 30 seriously embarrass the crew which is serving the gun. Since the successful application and practical operation 'of a device of this character is dependent upon the effect of the gases on the gun crew it is necessary in order to secure a maximum operating efiiciency to so control the final disposition of the escaping gases that the recoil brake will not only be effective but that the gun crew will not be seriouslyhampered.

By proper adjustment of the size, shape,

and disposition of the gas exits, I create a resultant movement 'of the gases after eX- pulsion which will deflect them in any desired direction. To these and other ends, my invention consists in the construction, arrangement and combination of parts, described hereinafter and pointed out inthe claims forming a part of this specification.

One embodiment of my invention is illustrated by way of example in the accompanying drawings, in which, k

` Fig. 1 is a side elevatlon of a gunemploying mymuzzle brake;

Fig. 2 is aside elevation of the muzzle brake, partly 1n longitudinal section toshow the1 arrangement'of the deflecting elements; an

Fig. '3 is a sectional v-iew taken on the line 3 3 of'Fig. 2. l

In the drawings in which like characters fof reference designate like or similar'parts, 1 indicates the barrel of agun, having an enlarged portion 2,which is screw threaded to receive a muzzle brake 3. The muzzle brake 3 is cylindrical' in shape and comprises an attaching collar 4, a rnt collar 5, and a plurality of spaced connecting ribs 6 to permit lateral expansion of the gases generated by explosion. 'The attaching collar 4 is formed with an annular fiange 7 against which is seated a baffle plate 8 secured by means of screw bolts '9. A'ring 10 thread-- edly mounted on the attaching collar 4 abuts against the baiilerplate 8 and receives the terminal portion of the screw bolts'9. The

elements of the muzzle brake 3 are internally threaded to receive a. series of spaced baflie plates 11 mounted on tie rods 12 and anchored in a base ring 13, which rests flush against the face of the muzzle.

The baflie rings 11 are formed with a bore slightly larger than the bore of the gun so. as to permit free passage of the projectile and they are furtl er provided with concave vrear faces of' variable degree to receive the impact ofthe gases and togovern the d irection of'expansion. The forward face of each ring is of irregular convexity so as to more readily direct the escaping gases into the concave :tace of the next preceding ring. The convex and concave faces of these rings are so formed and designed that the gases directed by a few of the rearmost rings will diverge forwardly, while the gases directedb the remaining rings w-ill diverge rearwar ly, it being preferable that the gases escaping from between the rear-l most rings have the least divergence of anyv of the forwardly diverted streams of gas, while the gas escaping from 'between the foremost rings will leave the least'divergence of any of the rearwardly directed streams of gas; the object being to leave the resultant rearward movement of the gases sufficiently divergent to avoid injury los' to the gun crew and gun mount, while at the same time securing a sufiicie'nt rearward direction. of the gases t0 provide a useful breaking force.

In operation, the force of the explosion generates gases which follow the projectile through the 4bore of the gun. These gases upon flowing from the muzzle of the gun` iinpinge upon the haiile rings A to N and escape through the spaces between the ribs (l: The direction of exit of the gases is shown by arrows a to n and is controlled by the degree of concavity of each particular ring. t will thus be seen that the gases following the direction a to e will move forwardly of the gun crew while the gases following the direction f to fn, will be diverted rearwardly towards 'the crew. By this arrangement the resultant movement of the gases after emission from the muzzle brake may be so Controlled that their final dissipation will not seriously affect the crew operating the gun. i

By proper adjustment of the size, shape and disposition of the bafie rings, it is possible to' create a resultant movement of the gases in any desired direction.

Having thus described my inventiomwhat I claim is:

1. A muzzle brake for guns comprising a casing and a plurality of spaced baffle rings, the rings nearest thegun muzzle having forwardly directed exits and the more remote casing formed with a plurality ofspacedV ribs and a set ofbaffle rings mounted on rods and adapted for threaded engagement within the casing.

4. A muzzle brake for guns provided with spaced discharge ports, the forwardly situated ports adapted to discharge gases in a rearwardly divergent direction; and the rearwardly situated ports adapted to discharge gases in a forwardly divergent direction.

5. A muzzle brake for guns provided with spaced discharge ports'arranged to direct the escaping gases along converging lines, whereby a resultant movement ofthe gases will be had in a direction to clear the gun crew.

JOHN B; ROSE.
