page_text: I, WILLIAM HENRY BECK, of 115 Cannon Street, in the City of London, Con-
sulting Engineer and Patent Agent, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, reference being had to the accom
panying sheet of Drawings and the letters and figures marked thereon:-
This invention relates to a new or improved rebounding gun-lock with double
and triple movement applicable to all fire arms with several fixed barrels and
internal hammers.
In the Drawings hereto annexed:
Figure 1 represents a section of the gun-lock, the barrels being supposed to be
to the left hand, the hammer C uncocked, and the rebound having been effected.
Figure 2 represents a section of the gun-lock, the barrels being supposed to be
to the left hand and the hammer C at full-cock.
These two Figures, 1 and 2, show the action of the spring lever H on the
ratchet b2
Figure 3 represents a section of the gun-lock similar to Figure 1 but the barrels
are supposed to be to the right.
Figure 4 represents a section of the gun-lock similar to Figure 2 but the barrels.
are supposed to be to the right.
These two Figures, 3 and 4, show more especially the action of the stopper G
forming the bent for full-cock. In Figure 4 the stopper G is engaged in the front
of the trigger A at the point a shown in Figure 5.
Figure 5 represents a section and front view of the trigger A.
Figure 6 the hammer axis B in one piece furnished with a small coiled friction
spring.

Figure 1.

page_text: Figure 14 side view and section of the spring I of the trigger A and of the
locking piece (fermeture).
The fire arm represented is a four barrelled pistol, the external form and the
locking piece (fermeture) of which is known.
E is an escapement lever pivotted at one end by a fulcrum screw a³ in the
mortice a of the trigger A, the other end taking into a mortice c² in the hammer C
and being held up against the upper part of the said mortice, by a spring e¹.
When the trigger A is pulled backwards it carries with it the lever E, the
shoulder e near the end of which (see Figure 9) acts upon the front upper edge of
the mortice c, and thereby causes the hammer C to turn backwards on its pivot
into the position shown in Figures 2 and 4.
By this movement the trigger A raises the spring arm H, which is attached to
it, so as to act on the teeth of the ratchet wheel b² and to cause the axis B to
rotate into the position necessary to bring the striking hammer b¹ opposite the
striker of, the barrel to be discharged. At the same time the stopper G, pressed.
by its spring g (Figure 12) turns on its pivot so as to bring the catch g (Figure 11).
in front of the trigger A at the part a (Figure 5).
The firearm is thus brought to full cock and ready for firing as shown in
Figures 2 and 4.
The firing is effected by pulling the trigger A. still further backwards. This
causes the hammer C to be turned further backwards on its pivot so as to describe
an arc of a circle which brings the upper part of the mortice c³ into such a position
that the hinder upper edge thereof presses down the end of the lever E until the
shoulder e is clear of the front upper edge of the said mortice whereby the
hammer C is released. The main spring D then forces the hammer C forward
through the intervention of the piece c, the axis B and striking hammer b¹ are
thereby driven forward, the latter forces forward the striker opposite to which it
may happen to be and the corresponding cartridge is thereby exploded. As the
axis B moves forward the ratchet wheel b on it comes against the part g¹ of the
stopper G (see Figure 11) and causes the said stopper to turn on its pivot so as to
withdraw the catch g from the front of the trigger A leaving the latter free to be
returned into its forward position (shown in Figures 1 and 3) by the action of the
trigger spring I as soon as the trigger is released by the finger.
As the trigger moves forward the portion of it marked A¹ comes against and
presses down one end of the rocking lever F the other end of which is thereby
forced upwards, and coming in contact with the part c¹ (see Figure 7) of the
hammer C, turns the latter backwards on its pivot slightly, that is, causes it to
rebound so as to enable the axis B and striking hammer b¹ to be pushed backwards
by the spring B₁ sufficiently to separate the hammer b' from the striker.
On again pulling the trigger the cycle of operations is repeated.
Having now particularly described, and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is
The new or improved gun-lock for fire-arms with several fixed barrels, arranged,
combined, and operating substantially as herein-before described, and illustrated in
the Drawings hereto. annexed.
