MESSES. SCHNEIDER AND CO.’S WORKS.
in order to absorb part of the recoil of the gun. This
device is funnel-shaped and is fixed to the muzzle ; it
is made with a hole slightly larger than the projectile, thus
allowing the latter to pass through freely. When a round
is fired, a wide cone of gas is emitted, the basis of which
is in a line with the rnuzzle end of the gun. The gas
strikes against the inside ot' the recoil check plate, and
is forced to the rear ; in doing so, it exerts a considérable
pressure on the funnel-shaped device, and tends to draw
the interposition of Belleville springs ; these served to
deaden the shocks caused by the firing of the gun.
Experiments made with this gun showed the recoils
to be more or less checked by the muzzle device, but the
gunners had to stand outside the wheels, not to be incon-
venienced by the hot gases that were driven to the rear.
Besides, this apparatus alone could not insure the stability
of the gun and did not take up recoil completely.

counteracts that of the recoil and checks it to a certain
extent. The carriage is rigid and consists of brackets
riveted together; the trail ends in a fixed spade with

with a pinion carried by the carriage bar. The pinion
is keyed on the same shaft with a hélicoïdal wheel, the |
latter driven by an endless screw, fitted on a shaft with
riage with Independent Axle (Fig. 910, and Fig. 912,
Plate CLIV.).—The following- are particulars of this gun :

,, projectile ... ... ... 5.2 kg. 11| Ib.
Muzzle velocity 550 m. 1804 ft.
Striking energy of projectile 80 t.-m. 206 foot-tons
The carriage consists of two steel-plate brackets joined
together by riveted plates forming transoms; it is supported
by the trail which rests on the ground and on an elastic
