Description
J. L. HATCHR MZZLE ATTACHMENT FOR GUNS July 15, 1930.
Filed June 6, 1927 Egg-E- Patented July 15, 1930 UNITED STATES PATENT OFFICE JAMES L. HATCHER, F THE UNITED STATES ARMY, WINCHESTER, 'VIRGINIA MUZZLE ATTACHMENT FOB GUNS Application filed June 6. 1927. Serial No. 196,951.
(GRANTED UNDER THE ACT 0F MARCH 3, 1883, AS AMENDED APRIL 30, 1928; 370 0. G. 757) The invention described herein may be manufactured and used by or for the Government for governmental purposes without the payment to me of any royalty thereon.
This invention relates to a muzzle attach# ment for guns and more specifically it has reference to that class of attachments serving separately or severally to conceal flash, check recoil, silence the report and arrest the tendency of the gun to climb.
The essential features which distinguish the presentattachment from thoseheretofore designed reside in the provisions for controlling and directing the admission ofv the gases into the dampening passage, confining them to the passage, and directing their discharge in a manner to utilize their energy in arresting the climb of the gun.
With the foregoing and other objects in view, my invention resides inthe 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 invention.
Fig. l is a longitudinal sectional view of the attachment mounted on the muzzle of a so gun.;
Flg. 2 1s a`sect1onal vlew on the llne 2-2 of Fig. 1. Y
Fig. 3 is a view infront elevation of the as sembly; r
Fig. 4 is a fragmentary longitudinal sectional view of a modified form of the attachment;
Fig. 5 is a front end viewof Fig. 4; Fig. Gis a detailed view of the bullet tube o having the impact plate directly mounted thereon.
lReferring to the drawings by numerals of reference:
The attachment comprises a tubular casing 5 interiorly threaded at the rear end 6 for securing it to the muzzle of a gun. Fixed in the casing is an impact and shearing plate 7 which is spaced from the rear end of the casing to provide an expansion chamber 8.
5o The plate 7 is in the form of a disk havingV marginal openin s 9 whose combined area/is at least and preferably equal to the area of the bullet passage in the rearwardly disposed tubular extension 10.
Disposed forwardly of the impact plate is a helical baiiie 11 which may embrace an axialA o and obtaining a downward thrust which will compensate for the tendency of the gun to climb.
The-device will function according to the same principle even with the defiection plate removed from the cap ring 15 but under such circumstances the forward extremity of the casing is modified as shown in Fig. 4 so that the assembly may be turned 180 whereby the discharge of the gases is directed upwardly as indicated in Fig. 5. In this case the area of reaction w-gz/ will exceed the discharge area ab.
As the projectile emerges from the gun and occupies t e axial passage 10 of ,the impact plate the be obliged to pass through the marginal openings 9 towards which they are directed by reason of the shape of the impact plate. The entrance of the gases into the dampening passage of the baliie is directed adjacent the wall of the casing and is of special significance in initiating circulation when the axial tube 12 is not incorporated in the assembly.. The axial tube 'l2 will secure the circuitous fiow of the gases and will conne them to the dampening passage.
I claim:
1. An attachment for guns embodying a casing, an impact plate spaced from the rear of the casing to provide an expansion chamases will be blocked olf and will i,
ber and formed with a rearwardly extending projectile passage, said plate having marginal openings whose combined area equals the area of the opening of the projectile passage, an axial imperforate tube in the casing forwardly of the impact plate and a helical bafe embracing the tube and terminating to provide a discharge area less than the reaction area of the casing.
2. An attachment for guns embodying a casing, an impact plate spaced from the rear of the Casin t0 provide an expansion chamber and forme with a rearwardly extending projectile passage, said plate having marginal openings whose combined area equals the area of the opening ofthe projectile passage, an axial imperforate tube in the casing forward- 1y of the impact plate, and a. helical baffle embracing the tube.
3. An attachment for guns embodying 'a casing, an axial imperforate tube in the casing spaced from its rear end, an impact plate embracing the tube forwardly of its rear extremity and havingmarginal openings whose combined area equals the area of the opening in the tube and a helical baille embracing the tube forwardly of the impact plate.
4. An attachment for guns embodying a casing, an axial imperforate tube in the casng spaced from its rear end, an impact pla-te embracing the tube forwardly of its rear extremity and having marginal openings and a helical baille embracing the tubeforwardly of the impact plate.
