Application .July 16, 1942, Serial No. 451,163

(Cl. Sil-14) 4 Claims.

This invention relates to flash hiders of the type adapted for use in concealing the flashes incidental to ring of rearms, particularly automatic weapons.

Objects of the invention include the provision of an efficient flash hider adapted to be secured to a iirearm muzzle and constructed of few parts in a simple and inexpensive manner; the provision of a flash hider comprising an elongated tube of larger diameter than the caliber of the firearm to which it is to be attached and having a series of particularly spaced bailles adjacent its exit end; the provision of a ash hider having only six parts of which three are exactly alike; and the provision of a flash hider as recited which may be made without the necessity of providing any special tools or dies for the purpose.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which Fig. 1 is a longitudinal section through the ash hider;

Fig. 2 is an elevation with parts removed;

Fig. 3 is an end View looking in the direction of arrow 3j Fig. 4 is an elevation of the front cap;

Fig. 5 is a view of the cap looking in the direction of arrow 5;

Fig. 6 is an exploded view of the bailles; and

Fig. '7 is a view of one of the discs looking in the direction of arrow l in Fig. 6.

Referring to the drawing in detail, the flash hider as here illustrated and conforming to the invention, comprises a long tube or cylinder IU open at both ends. A screw or other fastener I2 is mounted adjacent one end of the tube, and may be used to detachably secure the flash hider to a firearm barrel at the muzzle, the tube being intended to extend away from the muzzle. The flash hider may also be similarly secured over a compensator such as disclosed in my co-pending application Serial No. 375,224, filed January 6, 1941, if a compensator is used.

The tube IG is internally screw-threaded at its end opposite to the fastener I2, as shown at I4. A cap I6 comprising a short cylindrical body I8 externally screw-threaded to mesh with the interior threads of tube Ill, is provided, and the body I8 has a flange 20 which is round and extends radially outwardly beyond the body I8 so that its periphery aligns with the outside surface of the tube in short extension thereof. A second and wider ilange 22 extends inwardly o the body I8 and this ange comprises a iilial baille, being apertured at Z for the passage of. the bullet. A

There are three other baille elements in the tube, all three comprising structures exactly alike, but differently indicated for descriptive purposes as 26, 28, 30. Each baille element comprises a plane round disc 32 having 'a central A aperture for the bullet and a lateral peripheral ange 34 of a diameter dimension suicient to allow a tight iit in the tube, the flange extending to one side only of the disc. Baille element 26 is positioned to abut the end of cap body I8 with its flange 34 extending away from the cap. Element 28 is positioned next to element 26, their flanges extending toward each other and abutting to space their discs, or effective baille members, the desired distance apart.

Baille element 30 is located in greater spaced relation to element 28, by means of a cylindrical spacer 36, just fitting the inside of the tube, andthe flange of element 30 extends toward the spacer and the other bailles to peripherally abut the former and to act as a further spacing means. As shown, the bailles are four in number, and are grouped Well toward the exit end of the flash hider, rst baille 30 being in position to initially and roughly break up the explosion flashes, each of which will completely fill the tube from the gun muzzle to the rst baille, and bailles 2B, 26, 22 being positioned to more nely break up and completely disperse the initially broken-up flashes. The spaces 36 and flanges 34 act to reduce the diameter of the tube between bailles.

Repeated practice tests have shown that the spacing as here disclosed, together with the long length of the tube, is the most eflicient flash hider possible, using the simple and easily manufactured parts as described. It is thought that this efliciency results from providing the long unimp-eded chamber 38to take a complete explosion flash, then initially breaking it up by means of bafe 30, providing short and reduced chamber 40 for the roughly broken flashes, and finally dispersing the latter in the narrowly spaced bailles 28, 26, and 22, and very short chambers 42.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

l. A flash hider for firearms comprising a hollow tube adapted to be secured to a firearm at one end, a cap secured to the other end of the tube and extending a short way thereinto, a

baille element abutting said cap and having a short flange fitting thel interiorof said tube and extending away from said cap, a. second baille element similar to said first named baille element and positioned in said tube with its flange abutting the ilange of the first named baille element, a spacer sleeve fitting the'interior of said tube and having tan end abutting the second named baille element, said spacer being longer than the combined widths of said cap and said flanges, and a third baille abutting the other end of'said spacer. Y Y

2. A flash hider ias recited in the next preceding claim wherein said flanges and spacer are all of corresponding` thickness and are effective to Y reduce the interior diameter of the tube.

3. A flash hider for firearms comprising a hollow tube adapted to be attached to a firearm and having a chamber therein, a cap at one end of said tube, a pair of baille elements located in said chamber adjacent said cap and veach element having a similar lateral flange extending toward Veach other in abutting relation, a spacing sleeve in said chamber abutting one of said baille elements, and a third baille element having a Vflange extending toward and abutting said sleeve, the latter being of greater length than the combined lengths of said flanges.

4. A flash hider for firearms comprising a hollow tube adapted to be attached to a rearm and having a Ychamber therein, a cap at one end of said tube, a pair of baffle elements located in said chamber adjacent said cap and each element having a similar lateral ilange extending toward each other in abutting relation, a spacing sleeve in said chamber abutting one of said baille elements, Vand a third baille element having a flange extending toward and abutting said sleeve, the latter being of greater length than the combined lengths of said flanges, and allrsaid baille elements lying to one side of the transverse center of' said tube, whereby said chamber is broken up into a plurality of chambers of decreasing lengths toward said cap.
