Duration: 13:15

This video showcases the Lewis Light Machine Gun, highlighting its unique air-cooling shroud and clock-style recoil spring. Despite its mechanical complexity and difficult field stripping, the Lewis Gun proved accurate and reliable in testing, outperforming contemporaries like the Chauchat. The demonstration includes magazine loading, firing, and a unique clearing procedure.

Quick Summary

The Lewis Gun's air-cooling system uses a finned shroud and muzzle exhaust gases to draw air over the barrel. Its clock-style recoil spring is wound by gas pressure and releases to chamber the next round. Loading requires a special tool for the 47-round pan magazine, and clearing involves racking the action twice.

Frequently Asked Questions

How does the Lewis Gun's cooling system work?

The Lewis Gun features a distinctive aluminum finned shroud around the barrel. When fired, exhaust gases exiting the muzzle create suction, drawing cool air from the rear through the shroud and over the barrel for effective air cooling.

What is unique about the Lewis Gun's recoil spring?

It utilizes an unusual clock-style recoil spring. Gas pressure pushes a piston back, winding up this spring. The spring then releases, pushing the gas piston forward to chamber the next round, a mechanism housed near the trigger group.

How is the Lewis Gun magazine loaded?

The 47-round pan magazine is loaded using a specialized handle tool. Rounds are placed one by one into notches while rotating the drum, ensuring the rim of each .303 British cartridge is properly seated.

What is the proper clearing procedure for a Lewis Gun?

Clearing is unique: remove the drum, then rack the handle twice. This ensures any round potentially left in the feedway is ejected, as the chamber may appear clear but still hold a round.
