Heretofore the amunition chambers or barrels of the breech cylinders
of revolvers and other fire-arms after having turned for a portion of its
circumference were simply brought in front of the barrel of the arm or,
weapon, and their movement was only a rotatory one, around an axis.
The result of this arrangement was that a space or division existed,
between the breech cylinder and the adjacent extremity of the barrel,
thereby permitting a certain quantity of gas to escape from the powder,
and thus diminishing the projectile force of the arm or weapon.
Now this Invention relates to an improved arrangement of moveable,
breech for revolvers and other; repeating fire-arms, and to prevent the

page_text: escape of gas from the powder. It is based upon the combination of the
rotatory movement of the breech cylinder, by bringing together the
barrel and the breech cylinder in such a way that the revolution of such
cylinder causes the junction with and horizontal separation of the barrel
and the breech cylinder.
In this arrangement the breech cylinder after having revolved a
certain fraction or distance around, the horizontal axis becomes united
to or compact with the barrel by a movement of transmission parallel to
the same axis of one of these two parts (either the breech cylinder or
the barrel), and permits one or more notches or projections formed on
one of them to take into one or more corresponding depressions formed
on the other; these projections are disposed around the bore and may be
circular or polygonal, regular or irregular, or may form a curve of any
kind in such way that instead of discontinuity or interruption between
the breech cylinder and the barrel they become hermetically closed, and
each amunition chamber of the cylinder is successively united with the
barrel. At each fraction or portion of circumference or revolution the
breech cylinder is well held up or supported at the back, and the
powder is then able to produce its entire projectile force or effect without
loss of gas.
In the breech there is an arrangement for uniting the periodical
movement of rotation of the cylinder with the reciprocating motion of a
rod or spindle, which said rod or spindle serves to drive out the spent
cartridges, thus permitting a more rapid loading of the arm.
"
or
The striking or percussive force is imparted to the "cock
hammer by means of the trigger, which works springs and set in motion
notched catch pieces or clicks.
The bolting arrangement in front of the breech cylinder is held in
place by the aid of a spindle or rod formed in two pieces and joined
together by a screw. This bolting arrangement, the breech cylinder,
and the spindle or rod are kept well in place by means of abutments or
projections, but at the same time permitting the rotatory movement of
the breech cylinder.
A moveable plug or stopper held in place by a hinged spring serves to
close or release the charge or amunition chambers from the breech
cylinder, in order to allow the arm to be loaded.

page_text: The movement of the cock or hammer may be divided into three
priods, actions, or movements.
The breech cylinder carries in its back part as many indentations or
curves as there are charge or amunition chambers.
This arrangement of breech is also applicable to guns, pistols, carbines,
and other fire-arms of any calibre other than revolvers.
In another arrangement the junction of the barrel with the breech
cylinder is hermetically or air-tightly closed by a movement of the
barrel parallel to the axis of the breech cylinder, but in this arrange-
ment the spindle or rod for driving out the blanks or spent cartridges is
dispensed with, and the loading or unloading of the arm is effected by
detaching the breech cylinder from the fittings, stays, or stock. Hero
the striking appliances may be varied.
In order to disengage the breech cylinder the spindle rod or mandril
which is held by a spring against it is drawn out, and a toothed
projection being freed the breech cylinder comes out of the arm easily.
