Just before the cartridge is fired, a locking...

Loading And Firing

Drawing back the cylinder latch with the thumb permits the cylinder to be swung out to the left on its crane. The cylinder is loaded, then sv ung back into place until it clicks. The revolver may be fired now either by drawing the hammer back to full cock (single action) or by double action, that is, by drawing back on the trigger until the cy'inder revolves and locks and the hammer cocks and is released to fire the cartridge.

How The M Submachine Works

A loaded magazine being pushed into the magazine housing from celow until it ocks, the rocker arm is drawn back as far as it will go. This draws back the bolt, compresses the recoil springs and engages the sear in the bolt holding it in rearward position. At the same time the cover over the ejection port flies open. Pressure on tine trigger will row release the bolt which will drive forward, forcing the cartridge from the magazine into the firing chamber, slipping the extractor over the head of...

How The Gun Works

Like the Revelli, Fiat and Schwarzlose, this gun is oper-eted partly by recoil of the moving parts and partly by what is called projection of the spent case, which means simply blowback as the empty case is forced back against the face of the bolt. This system, as in the case of the early Japanese machine guns, requires the incorporation in the gun of a special device which will spray oil on the cartridges as they are inserted in the firing chamber. This device also lubricates the moving parts....

The rear of the tube while most of the force pushes forward to drive the projectile out the muzzle of the tube, the weapon fires without recoil. This principle permits rhe use of very sensitive high explosives.

Adjusting

The most important adjustment on a machine gun of this type is the head space. This is the correct space between the head of the cartridge in the firing chamber and the face of the lock. Should this space be too great, the head of the cartridge will not be held firmly during the moment of high breech pressure. This may bulge the cartridge case so that extraction will be extremely hard, or it may rip the head completely off the cartridge case, resulting in an even more serious am. On the other...

Thus the oil is permitted to escape freely from the opening in the center of the piston valve as well as at the edge of the valve near the tube wall, and so prepare it for the rearward motion. Automatic Fire If the trigger is pressed and held down, the sear is...

Special Note On Japanese Machine Guns

In the last few years the Japanese have imitated the Lewis, Vickers, Browning and Bren guns. Some of these weapons have been so carefully imitated, that they will successfully handle the British .303 cartridge. One reason for this development may be large quantities ot British ammunition in possession of the Japanese. In developing cartridges, they have made the fatal mistake of using several designs in 7.7mm (or .303). Some weapons will take this cartridge with a rim some when the cartridge...

How The Mp Works

The loaded magazine inserted from below is held securely in place by the magazine lock. The firing pin is attached to the forward end of the telescope housing. It passes through the hole in the center of the bolt, while the abutment behind it lodges into the head of the bolt recess. As the bolt is drawn back by its handle, or forced back by the force of an explosion, it telescopes the three piece recoil spring housing (which carries the firing pin) and compresses the recoil spring which is...

Note On Cooling System Of Lewis

A very ingenious cooling system is employed in this gun. A oarrel mouthpiece is screwed over the end of the barrel and has a cone shaped interior. As the bullet leaves the muzzle, the expanding gases strike against the cone shaped interior of this barrel mouth piece, rebound and strike against the front end of the radiator casing, thus forcing all the air out in front of them. This creates a suction behind which draws a current of air from the rear of the gun through the rear casing and around...

Stoppages And Immediate Action

Small Cut Arm

Th's weapon is so simple and rugged in construction that very few stoppages are likely to be encountered if the weapon is given reasonable care and cleaning. If the weapon has been kept clean and lightly oiled (too much oil slows down the mechanism), stoppages are like'y to be caused by either faulty ammunition or defective magazines. If the magazine spring has been weakened or the lips of the magazine damaged, the weapon may fail to feed. If the ammunition is ocfcctive, it may fail to fire...

Gas Action

As the bullet passes over the gas vent in the barrel, some gas escapes through and into the gas cylinder, then through the gas regulator to strike a sharp blow against the piston head. This sudden thrust drives the piston and its extension to the rear, and the inclined ramp on the piston post bearing against the breech block lowers the rear end of the block out of engagement with the resistance space at the rear of the barrel extension, unlocking Further rearward motion of the piston extension...
