The 1-pounder semiautomatic gun and carriage was primarily intended for landing purposes, but it has been used in trench warfare and to accompany infantry troops. This equipment is well adapted to the latter uses, due to the fact that its weight is such, as to permit it to be readily transported from place to place by man power.
The gun is made of nickel steel, with the gun body and breech end being forged in one piece. The breech mechanism is of the Bethlehem semiautomatic type in which the breech is opened, the case ejected, and the firing pin cocked on the counter recoil. The block is closed by a spring which is compressed during counter recoil and held in that position by the extractor until tripped by the insertion of another round.
The carriage is of the long recoil type and consists essentially of a cradle, pivot yoke, trail, wheels, and axel. The cradle supports the gun, forms a housing for the recoil mechanism, and is itself supported by trunnions bearing on the pivot yoke. The recoil mechanism is located above the gun and consists of a hydraulic cylinder and counter recoil springs. No elevating and traversing mechanisms are provided as the laying can be readily accomplished by means of a shoulder guard and grip.
Open sights are furnished and a bullet proof armor plate shield affords protection for the cannonneers.
Fixed ammunition is used, and is packed for transportation in the steel boxes containing 60 rounds each. A hand cart for carrying four boxes, 240 rounds, is issued, the front and the lid of this cart, being bullet proof.
