, MUZZLE ATTACHMENT non AuToMATIo "GUNS.
Application filed April 12, 1927. Serial No. 183,153.-
(GRANTED UNDER THE PROVISIONS on THE Actor 1 The invention described hereiny-i-f patented, may be manufactured and used byor for the Government for governmental pur= poses without the payment to 5 royalty thereon.
.The subject of this invention is a muzzle attachment for automatic guns.
In employing blank ammunition having a reduced powder charge with service weapons, it is customary to place an attachment at the muzzle of the gun which will serve to retard the escaping gases and thereby insure proper functioning of the operative elements of the gun. These attach- 5 ments are generally provided with a restricted opening to cause disintegration of the paper or wooden bullet as it leaves themuzzle. However, it frequently occurs that the bullet will become lodged in the opening and with the barrel thus occluded the pressure is excessive and drives the recoiling members through the back plate of the gun. This condition in addition to damaging the gun invariably results in injury to the gunner. I
Accordingly it is proposed in the present invention to provide a muzzle attachment in which the disintegrating plug is secured by a frangible connection. 1
With the foregoing andother objects in view, my invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invent-ion.
A practical embodiment of the invention is illustrated in the accompanying drawings, wherein:
Fig. 1 is a longitudinal sectional view of the attachment with the plug in normal position;
Fig. 2 is'a similar view with the plug in released position;
Figs. 3 and 4 are sectional views on the respective lines of Fig. 1.
Referring to the drawings by numerals of reference:
The attachment comprises a tubular 'membeer or sleeve 5 which is externally threaded.
me of any Manon a, 1883, 22 sTAT. M2
as at 6 at its muzzle of the gun'and is internally threaded as at- 7 at its forward end forthe reception of a'stop member 8 The rear extremity of the sleeve is provided with an inturned flange 9 against which is seated a plug 10 having a restricted bore 11 of less diameter than the bore of the gun barrel and this bore merges with a flared mouth 12. The plug is preferably secured to the sleeve by means of a suitable number of shear pins 13.
As the wood or paper bullet of the blank carriage is discharged throughthe restricted bore it will be disintegrated while the. gases being prevented from rapid escape will provide sufficient backward pressure to insure the normal recoil of the moving members which is necessary for automatic action of the weapon.
In the event that the bullet becomes lodged in the restricted bore of the plug the gases can not escape and the pressure developed and exerted on the plug will cause the shear pin 13 to be severed, allowing the plug to Y be moved forwardly in the sleeve untilbrought up against the stop member 8.
uring this movement the sleeve constitutes an expansion chamber andthe plug will unrear end for attachment to'the cover a number of relief ports 14 provided in the length of the sleeve for the escape of the gases.
Since the pressure has been relieved through the muzzlethe recoiling members will not be energized and the automatic'action of the gun will be discontinued.
The stop member 8 plays an important role when the attachment is mounted on synchronized airplane guns as the plug will be prevented from issuing and striking the blades of the propeller.
The assembly is so arranged that the replacement of the frangible connection will involve only the simple-operation of removing the plug by unscrewing the stop memer 8, removing the parts of the shear pins and reassembling. i
I claim:
1. An attachment for automatic guns including a sleeve attachable at the muzzleof a gun, said sleeve provided with an inturned flange at its rear end and a lurality of ports along its length, a plug having a. restricted bore less than the bore of the gun, shear pins connecting the'plug to the :sleeve and a stop member removably attached to the forward end of the sleeve. r
