The Works Of Messrs. Schneider And Co.

290 MESSRS. SCHNEIDER AND CO.’S WORKS direct to the breech end of the gun ; a neck fittecl with a valve is placed in the centre of the system, and serves to till the recoil cylinder. The shoulder-piece, to whjch the recoil-rod is fixed, is fitted on the right-hand side, with an arm on which the rod of the right-hand recuperator is bolted. The recuperators are formed of sets of springs placed inside the cylindrical tubes fixed to the cradle; these springs are divided by diaphragme, and are placed on a central rod. The required elevation is obtained by means of a screw jointed on the cradle and which turns in a nut, the latter being worked by two bevel wheels—one keyed on the nui, the other on a hollow horizontal shaft set in motion by a handwheel driven by the gunner. Lateral training is obtained by displacing the trail. To obtain this, the spade In a modifiée! type the particulars were : Weight of gun... ,, mounting ,, projectile Muzzle velocity Energy of projectile 348 kg. 638 kg. 6.5 kg. 500 m. 111.5 t-iu. 769 1b. 1406 1b. 1b. 1903 ft. 371 foot-tons In these models the following properties were shown to exist in a high degree under test : 1. Reduced recoil, allo wing continuée! fire. 2. Rapid and sustained fire at comparatively short range, without re-training the gun. 3. Great stability during recoil on ordinary ground. 4. Very slight deviation of the gun. 5. Strong and absolutely safe breech-closing device. Fig. 927. 3-in. Gun with Telescopic Recoil Brake. is provided with a rack worked from a pinion keyed on a shaft with a pitclied wheel driven by a plate-chain. The latter is worked by a pinion keyed on a shaft placed concentric with the hollow shaft for elevating the gun ' The two handwheels for elevating the gun and for lateral j training are therefore on the same centre. 75 - Millimétré (2.952 - In.) Gun, Long Type, on Carriage with Trail-Spade and Hydraulic Recoil Cylinders (Figs. 928 to 934, and Fig. 937, Plate CLVI., and Figs. 935, 936 and 938).—The following are particulars of the gun : Weight of gun... ,, carriage ,, projectile Muzzle velocity Energy of projectile 355 kg. 635 kg. 6.5 kg. 500 m. 83 t-m 782 1b. 1399 1b. 14’ 1b. 1640 ft. 276 foot-tons 6. High ballistic power comparée! with the weight of the gun. 7. Complété protection of parts against gi-ape-shot and dust. The gun is of forged and hardened steel; it is 33.3 calibres in length, and is made in two parts : the tube in which the breech-block is screwed, and the jacket, which covers the tube for a length of 1.210 metres (47.637 in.). The force of recoil is transmitted to the hydraulic recoil cylinders by the jacket, so that the tube has not to withstand any efforts that would tend to affect the breech mechanism. The gun is connected to the recoil cylinders by means of dovetailed flanges, which form a strong attachaient, but allow the system to be taken to pièces rapidly. The gun has been designed to take a truncated conical metallic Cartridge ; it is therefore not fitted with any mechanism for obturation. The breech-block can,
