from a hopper and guide them as they are pushed by the lock-tubes
into the chambers. In rear of the carrier-block, also on the shaft, is a
1ock-cylinder, in whose surface are also grooves, continuations of those
in the carrier-block. The e guide the locks, which not onl,y fire tile car ..
tridges but support their heads against the pressure of the powder-gas.
The lock-cylinuer is splined to the shaft to pre•ent turning; a nut ou
the shaft prevents it from lipping to the rear. The carrier-block is
connected by a dowel-pin with the rear barrel-plate and the lock-cylinder.
A toothed wheel at the rear extremity of the shaft completes the
rotating system. A fi·ame, to which trunnions are attached, extend ·
along the sides and front of tbe barrels. A bronze casing firmly
screwed to the frame protects tile locks, lock-cylinder, &c.; it also con·

shaft, the frame transom being journaled for its front .
. Inside the caRing, and connected with the diaphragm, is a hollow cyl­
Inder, having in its iuter;or nrface two spiral or cam groo>es, whicil
receive lugs on the locks. Tbe groo>e are connected at the front by a
plane surface, against vrhich the rear ends of the locks are supported
at the instant of firing. The cylinder, or cam, with its grooves being
fixed, while the locks '11-ith the lock-cylinder, &c., rotate, the locks are
alternately advancing and retreating, due to the lugs following the
grooves. Each lock-tube is pro>ided with a firing-pin and spring and
a hook-shaped extractor. The rear end of the firing-pin terminate in
a button which enter au uuder-et1t groove in a steel projection called
