XXXIII.—SCHNEIDER-CANET QUICK-FIRING GUNS AND MOUNTINGS
(MODERN TYPES).
Recent Types of Quick - Firing Schneider - Canet
Guns. Diese are based 011 the 1888 pattern, and also for
certain parts, on the earlier types previously described.
4lie gun itself, as a rule, is the same, with the exception
that in certain cases the one-motion cylindrical breech-
block has been replacée! by the concentric-threaded type.
Die mounting reprocluces certain primary arrangements
■of the 1888 pattern, and to a certain extent, the design
with lugs for fixing the brake and recuperator rods.
c. The front coil, which joins the gun tube to the jacket.
d. The breech mechanism, of the concentric-threaded type,
with extra quick-opening action, already described.
The mounting consists of the bedplate bolted on the
deck ; the movable slide that rests on the bedplate, with
the interposition of a pivot; the oscillating liousing, or
jacket, which carries the gun, and rests in the slide. The

■50-calibre gun mounting, mentioned in the descriptions of
the first quick-firing Schneider-Canet guns. We propose,
as we have already done for the 1888 pattern, to give a
■complété description of each type of mounting.
47-Millimetre (1.850-In.) 60-Calibre High-Power
Quick-Firing Guns (Fig. 753, and Fig. 754, Plate
CXXXL).
The gun is of steel throughout, and consists of four
parts : a. L'he inside tube that runs the whole length
of the bore, and bears in the rear against a projection
of the jacket. b, Uie jacket, in which is eut the breech
seating, and which is provided in the rear with a coil made
slide, housing, and gun, turn in two guiding collars with a
vertical axis, for training the gun. The housing and gun
oscillate round the housing trunnions, for obtaining the
required elevation.
