The cam imparted a reciprocating motion to the locks when the gun rotated.Īlso in the casing was a cocking ring with projections to cock and fire the gun.

In front of the casing was a cam with spiral surfaces.

The casing was partitioned, and through this opening the barrel shaft was journaled. The carrier was grooved and the lock cylinder was drilled with holes corresponding to the barrels. The barrels, a carrier, and a lock cylinder were separate and all mounted on a solid plate revolving around a central shaft, mounted on an oblong fixed frame. Each barrel fires once per revolution at about the same position. A British 1865 Gatling gun at The Gatling gun operated by a hand-crank mechanism, with six barrels revolving around a central shaft (although some models had as many as ten). By this time, the had been issued the modern tripod-mounted using the round, which they employed to defeat the Spanish infantry at the battle of.īasic design. Despite this remarkable achievement, the Gatling's weight and cumbersome artillery carriage hindered its ability to keep up with infantry forces over difficult ground, particularly in Cuba, where roads were often little more than jungle footpaths. During the American charge up San Juan and Kettle hills, the three guns fired a total of 18,000.30 Army rounds in 8 1/2 minutes (an average of over 700 rounds per minute per gun of continuous fire) against Spanish troop positions along the crest of both hills, wreaking terrible carnage. Three of the Gatlings with swivel mountings were used with great success against the Spanish defenders.
