page_text: LETTERS PATENT to Charles Larbaud, of Paris, (Rue du Temple,
No. 184,) Département de la Seine, for the Invention of "A NEW
SYSTEM OF TRIGGER, APPLIED TO PLAY ARMS, SUCH AS PISTOLS, FUSILS,
RIPLES. CANNONS. GUNS."
Sealed the 15th July 1853, and dated the 5th May 1858.
COMPLETE SPECIFICATION filed by the said Charles Larbaud at
the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 5th May 1858, pursuant to the 9th section of
the Patent Law Amendment Act, 1852.
I, CHARLES LARBAUD, do hereby declare the nature of the said
Invention for A NEW SYSTEM OF TRIGGER, APPLIED TO PLAY ARMS, SUCH
AS PISTOLS, FUSILS, RIFLES, GUNS, AND CANNONS," to be as follows:-
DESCRIPTION OF THE SEVERAL PIECES COMPOSING THE ENSEMBLE
OF MY NEW SYSTEM OF TRIGGER.
I present, as a sample, only a pistol, but I intend to appropriate
the same system of trigger to fusils, rifles, and guns, without making
any change in the form of the piece hereunder mentioned...

pieces composing the system of trigger.

2. Transversal section along the line 1, 2.
3. Under diagram of the arm barrel.
4, 5. Longitudinal and transversal sections of the fixed iron 5
barrel, which receives a rolled spring.
6, 7. Elevation and view by an end of the rolled spring.
8, 9. Longitudinal and transversal sections of the moveable
tube, which bears the piston.
10, 11. View of an extremity and over-diagram of the spring, 1
moved by the tumbler.
A, a stretched iron barrel, without soldering, having an opening for
the passing of the spring moved by the tumbler.
B, a tumbler with a lift b, stirring over a horizontal axis.
C, a fixed iron tube adapted to the stock.
D, a moveable tube, with a piston d; it incloses the fixed tube C,
and bears a ring &³.
E, a rolled spring fastened at c, in the interior of the fixed tube C,
and at e¹, to the piston d, in the moveable tube D.
1
F, a spring placed under the tubes. It is fastened to the stock at f, 2
and crooked in order to stop the moveable tube D, by the means of the
ring d', when the spring E, slackens.
The head f, of the spring F, bas a hole in which the tumbler lift b,
is fastened; it just hits under the moveable tube D, the ring d³, and
hinders the spring from slackling when the system is rammed into the 2
stock.
G, a rammer for bending the rolled spring E, by pushing he
system towards the stock.
H, a cork fastened to the aim by a little chain.
The Figure 1, presents the system of trigger when tho rolled s
spring E, is bended. The spring F, placed under the tubes C, and D,
maintains the tube D, in the position showed by the Drawing. When
the tumbler D, is moved, the head f", of the spring F, falls; this last
piece going-out from the ring d', the rolled spring E, slackens, and

page_text: makes the moveable tube to be chased horizontally towards the vent of
the arm; at the same time the piston d, throws out, with great noise
and detonation produced by the displacing of the air, the projectile-
introduced into the barrel before the piston. The ring d, stops near
the cog f, of the spring F, in order to prevent the tube D, and the
piston d, from going out of the barrel.
