Jacobson Automatic Carbine Model 1

Description

The Jacobson Automatic Carbine is not a true carbine at all, but rather a pistol-caliber submachinegun. It was designed by Dr. Emmanuel Jacobson for use by agents of the U.S. Secret Service in combating some of its more notorious foes. The U.S. Army adopted the weapon on a limited basis in 1899 (as the M98) to fight Philippine rebels and a number were used in defending New York from the Kaiser's forces in 1901.

The action is based on that designed by Hiram Maxim. The rounds are actually contained in a cloth belt fed from a box attached to the left-hand side of the weapon. As the weapon has a tendency to climb up and to the right, this placement helps compensate for the recoil. Reloading requires the firer to place another belt into the box, lift the feed cover and seat the first cartridge, close the feed cover and pull the charging handle -- steps requiring two actions on the part of the firer.

By the turn of the century the more-efficient box magazine had become popular and the JACM1 was phased out in U.S. service. The weapon was not popular on the civilian market. Nowadays the weapon is considered a collector's item and is extremely rare.
