bar. The magazine is loaded through an aperture in
the butt plate, the opening of the spring cover of which causes the two
ratchet bars to be depressed, so that the magazine can be filled by
passing the cartridges along a smooth middle bar. The act of closing the
spring cover again brings the two ratchet bars into play.

By means of a cut-off the ratchet bars can be prevented from acting, and
the piece used as a single loader.

_Kropatschek Magazine Rifle_.--This rifle, which is the small arm of the
French navy, has a bolt-action rifle resembling the Gras (see Fig. 9).

The magazine is a brass tube underneath the barrel, as in the
Winchester, Vetterli, Mauser, and other rifles of class 1. It contains
six cartridges, while a seventh can be placed in the trough or carrier,
T.

When the breech is opened by pulling back the bolt, a projection on the
latter strikes the carrier at N, causing its front extremity to raise
the cartridge into the position shown in the section. This movement is
accelerated by the spring, A, acting against a knife-edge projection on
the trough, T; in the upper position of the trough, the spring acts upon
one face of the angle, and upon the other face when in the lower
position.

On closing the breech, the bolt pushes the cartridge into the chamber,
and when the handle is locked down to the right, a part of the bolt
presses against a stud, and thus depresses the trough to be ready to
receive another cartridge from the magazine.

The magazine can be cut off and the rifle used as a single loader by
pushing forward a thumb-piece on the right side of the shoe. The effect
of this is that, on turning down the handle to lock the bolt, the latter
does not act on the stud to depress the carrier, so that no fresh
cartridges are fed up from the magazine.

[Illustration: FIG. 10.--LEE MAGAZINE GUN]

There is a projection, Z, on the fore part of the carrier, which keeps
the next cartridge from leaving the magazine while the trough is in the
upper or loading position. A supplementary cartridge stop, R, pivoted at
P and having a spring, L, underneath it, acts in conjunction with Z in
retaining the cartridges in the magazine, and especially in preventing
more than one at a time from passing out into the carrier when the
latter is depressed; it also retains the cartridges in the magazine tube
while the latter is being filled.
