GAS-OPERATED LOCK FOR AUTOMATIC RECOIL-OPERATED WEAPONS Filed Jan. 8, 1944 Ind/e ni'or Patented Mar. 27,
UNITED STATES PATENT" OFFICE GAS-OPERATED LOOK FOR AUTOMATIC RECOIL-OPERATED WEAPONS 1 Claim.
The invention relates to.an improvement in recoil-operated weapons in which a gas-operated lock prevents recoil of the gun barrel until the [bullet has passed the gas-port in the barrel;
and the object of the improvement is to permit the gun-powder gases to expand more forcibly, increasing the velocity and effective range of the Weapons bullets.
One form of the invention is illustrated in the accompanying drawing, in which Figure 1 is a vertical section of the muzzle portion of an automatic recoil-operated weapons barrel and frame; Figure 2 is the same vertical section at recoil position.
The upper portion of the piston I fits into the piston recess bore 2 in the barrel 3, the lower portion of the piston I fits into the piston bore 4 in the frame extension 5; efiectively locking the barrel 3 and the frame extension 5 together (see Fig. 1).
Upon discharge of the cartridge the bullet 6 passes the gas-port I, the piston I is driven down by the expanding gases 8, compressing the piston return coil-spring 9 and releasing the barrel 3 which recoils to the normal recoil position (see Fig. 2).
Upon counter-recoil the barrel 3 returns to the forward position (see Fig. 1), and the piston return coil-spring 9 forces the piston I into the piston recess bore 2 of the barrel 3.
The upper edge of the piston I is slightly rounded (radius) ID, the outer edge of the piston recess bore 2 is slightly rounded (radius) II, to
prevent shearing the edges of the piston I and the piston recess bore 2 as the barrel 3 recoils over the piston I (see Fig. 1 and Fig. 2).
The retaining plug screw I2 supports the piston return coil-spring 9 and the piston I in position in the piston bore 4 of the frame exten-.
Pulling downward on the piston extension pin I3 provides a manual release of the barrel 3, permitting the first cartridge to load into the chamber of the automatic recoil-operated weapon.
The part of the recoil-operated weapon not shown in the drawing forms no art of the present invention.
I am aware that prior to my invention automatic weapons have been made with gas-operated mechanisms. I therefore do not claim such a combination broadly; but
I claim:
The combination, in a recoil-operated weapon having a fixed frame and a recoiling barrel, of a gas-operated recoil delay lock having a gas port and a cylindrical piston recess bore in the barrel, a cylindrical piston bore through the extended portion of said frame, a cylindrical piston having an extension pin as an integral part, a retaining plug screw, said extension pin fitting in a bore in the retaining plug screw and stabilizing said piston and being a manual release for said barrel,. said piston locking said frame and said barrel together and communicating with said ibores, a piston return coil spring bearing against said piston and said retaining plug screw,
said plug screw retaining said piston return coil spring and said piston in said bores.
