Schneider-Canet 120mm field howitzer type O.C. 120 N° 2



I. General properties


The power is established by means of a projectile weighting 21 kg shot with a muzzle velocity of 330 m/s.

The mobility is very high due not only to the little weight of wagons and carriages.

The steadiness on firing is provided by the size of the recoiling body, and the length of the recoil. The traversing gear shifting on the axletree bed suppressed the entire systemic component which tends to deregulate the traversing.

The return in firing position is always complete under the highest angles by means of the force of the pneumatic recuperator, as well as soft, constant and without shock thanks to the action of the check buffer assures a return in firing position regular and without shock. The leakage of the air is impossible; since the air recuperator-tank is arranged like a bottle filled half with water, and half with liquid, and resting on its top.

The safety on fire is complete; the mechanical safety-pieces of the breech prevent any trouble.

The protection of the gunners is perfectly assured thanks to the gun-shield.


II. Features


Gun-body hooped to the muzzle composed by a tube and two jackets.

Breech with eccentric screw mechanism, interrupted threads, opening with an uninterrupted single action of the hand-lever, fastening automatically with a perfect closing and opening in order to make easy the loading. The cartridge case is automatically ejected when the breech is opened.

Loading tray lodged in the breech recess, in order to prevent the coming back of the ammunition placed in the chamber, when the howitzer is loaded at high angles.

Repeat firing device with hammer and mechanical safety arrangements against 1) the slipping of the breech when the shot is fired; 2) prolonged fires; 3) premature fires; 4) fires before the breech is closed.

Sleigh composed by a block of forged steel, where the housing for the buffer, the run-out and the air run-out tanks are drilled.

Recoil hydraulic buffer separate from the run-out, and containing the check buffer.

Return cylinder with air run-out tanks, requiring only couplings watertight to the liquid.

Cradle of stamped steel sheet carrying the slides which guide the howitzer during the whole length of the recoil. This long guidance prevents the lateral shifting of the howitzer during the recoil.

Elevating gear composed by a train of gears driving toothed arc attached to the cradle.

Sighting gear with tapered cone shaped drum and goniometer, which enables to correct the angle of sight and the difference of level of the wheels.

Carriage of stamped steel sheet, composed by the head of the carriage, the trail, and the trail-end.

Seat for the aimer.

Traversing on axletree bed.

Trail spade composed by a fixed ploughshare in forged steel for firing in rocky ground, and a wide moveable part, in steel sheet, for firing in ordinary ground.

Wooden wheels with tyres and naves of steel.

Gun-shield made by steel sheet of the French artillery type.

Two connecting travelling brake, fixed to the top of the trail, and engaging in a sound cross-piece placed in the backside of the cradle, and in a remote point of the trunnions, offering a great firmness to the mooring of the wheels.

Wheel-brake with screw, and wide brake-shoe.

Gun and wagon limber of the same kind, with cases for 10 full charges, and knapsack-rack with grid to carry the gunners’ luggage.

Armoured wagon body tip-up type, carrying 24 full charges.

Separated ammunition composed by loaded cartridge-cases, and projectiles lodged in cells.

Cartridge-cases loaded with pure nitrocellulose powder made in France.

Thin-walled high explosive shell equipped with detonator, and loaded with high explosive.

Shrapnel with charge at the bottom equipped with time and percussion fuze.

Fuze-setter for a quick and exact setting time and percussion fuzes.
