IMPROVEMENTS IN THE LOCKS OF FIRE-ARMS
Year: 1881

page_text: LETTERS PATENT to Edouard Bled and Edmond Richoux, both of Paris, in the
Republic of France, Gentleman, and Jean Warnant, of Liege, in the Kingdom
of Belgium, Fire-arm Manufacturer, for an Invention of "IMPROVEMENTS IN
THE LOCKS OF FIRE-ARMS."
PROVISIONAL SPECIFICATION left by the said Edouard Bled, Edmond
Richoux and Jean Warnant at the Office of the Commissioners of Patents on
the 16th December 1881.
EDOUARD BLED and EDMOND RICHOUX both of Paris in the Republic of Franco
Gentlemen and JEAN WARNANT of Liege in the Kingdom of Belgium, Fire-arm
Manufacturer. "IMPROVEMENTS IN THE LOCKS OF FIRE-ARMS."
Our Invention relates to improvements in the locks of all kinds of fire arms, but
more particularly of revolvers.
In the accompanying Drawings we have shown a revolving pistol male according
to our Invention. Figure 1 is a central longitudinal section, the hammer being at
half cock. Figure 2 shows part of the same section with the hammer at full cock.
Figures 3. 4. 5 and 6 represent the parts of the lock separately. Figure 7 illus-
trates the action of the spring in raising the hammer to half cock. In all the
Figures the same letters of reference indicate identical parts.
at is the tumbler and hammer in one provided with a projecting nose band with a
rear projection c to be acted on by the main spring for raising the hammer to half
cock as hereafter described. d is the trigger provided with a curved nose or
projection e adapted to be lifted by the nose b of the tumbler when the hammer is
full cocked by the thumb. f is a pawl pivoted to the trigger and engaging with
ratchet teeth on the rear of the cylinder in order to rotate it and bring its chambers
successively in line with the hammer. g is a double branched main spring. The
upper bianch takes directly under the hammer while the lower branch is extended
so as to press on an inclined shoulder h upon the pawlf whereby to keep the pawl
up to the revolving cylinder and press the trigger d downwards. The lower branch

page_text: of the spring g has a flat part which is slit to form a spring portion m, as shown
in Figure 6, to act on the projection c of the tumbler.
The action of the lock is as follows:-When the trigger d is pulled, its shoulder i
takes under the nose band lifts the hammer until i escapes from b whereupon the
hammer falls by the action of the upper branch of the main spring g and fires the
cartridge, the cylinder being meanwhile held in the proper position by a projection k
on the trigger engaging in one of the no.ches cut around its circumference. The
trigger on being released from the pressure of the finger is returned to its first
position by the pre-sure of the lower branch of the main spring g upon the
shoulder h. During this return movement of the trigger, the Hat part of the
lower branch of spring g comes down in contact with the projection c of the tumbler,
but as the extremity of the small spring portion m is enlarged and rounded, whilst
that of the flat part is bevelled, the spring m touches first and is slightly bent as is
shown in Figure 7. Now as the downward motion of the lower branch of
spring g is continued, the angle of the projection c with the flat part is altered,
the spring m exerts more leverage and acquires sufficient power to move the
projection c a little lower and push it away from the flat part as
seen in
Figure 1, thereby raising the hammer until the shoulder i of the trigger takes
under the nose b and the extremity of projection e comes into contact with the
top of b as in Figure 1. The hammer is then at half cock ready for the next
movement. If instead of being raised by the trigger, the hammer were to be
cocked by the thumb the nose b would lift the projection e of the trigger until the
one engages in the notch of the other as shown in Figure 2.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Edouard Bled, Edmond Richoux, and Jean Warnant in the Great
Seal Patent Office on the 16th June 1882.
EDOUARD BLED and EDMOND RICHOUX both of Paris in the Republic of France,
Gentlemen, and JEAN WARNANT of Liège in the Kingdom of Belgium, Fire-arm
Manufacturer "IMPROVEMENTS IN THE LOCKS OF FIRE-ARMS."
Our Invention relates to improvements in the locks of all kinds of fire-arms, but
more particularly of revolvers.
In the accompanying Drawings we have shown a revolving pistol made according
to our Invention. Figure 1 is a central longitudinal section, the hammer being at
balf cock. Figure 2 shows part of the same section with the hammer at full cock.
Figures 3. 4. 5. and 6 represent the parts of the locks separately. Figure 7 illus-
trates the action of the spring in raising the hammer to half cock. In all the
Figures the same letters of reference indicate identical parts.
a is the tumbler and hammer in one provided with a projecting nose band with
a rear projection c to be acted on by the main spring for raising the haminer to
half cock as hereafter described. d is the trigger provided with a curved nose or
projection e adapted to be lifted by the nose b of the tumbler when the hammer
is full cocked by the thumb. f is a pawl pivoted to the trigger and engaging with
ratchet teeth on the rear of the cylinder in order to rotate it and bring its chambers
successively in line with the hammer. g is a double branched main spring. The
upper branch takes directly under the hammer while the lower branch is extended
so as to press on an inclined shoulder h upon the pawl f whereby to keep the pawl
up to the revolving cylinder and press the trigger d downwards. The lower branch
of the spring g has a flat part which is slit to form a spring portion m as shown in
Figure 6 to act on the projection c of the tumbler.
The action of the lock is as follows:-When the trigger d is pulled, its shoulder i
takes under the nose band lifts the hammer until i escapes from b, whereupon the
hammer falls by the action of the upper branch of the main spring g and fires the
cartridge, the cylinder being meanwhile held in the proper position by a projection k
on the trigger engaging in one of the notches cut around its circumference. The
trigger on being released by the finger is returned to its first position by the
pressure of the lower branch of the main spring g upon the shoulder h. During
this return movement of the trigger the flat part of the lower branch of spring g
comes down in contact with the projection c of the tumbler, but as the extremity
of the small spring portion m is enlarged and rounded whilst that of the Hat part l
is bevelled, the spring m touches first and is slightly bent as is shown in Figure 7.
Now as the downward motion of the lower branch of spring 7 is continued, the
angle of the projection c with the flat part-l is altered, the spring m exerts more
leverage and acquires sufficient power to move the projection c a little lower and
push it away from the flat part as is seen in Figure 1, thereby raising the
hammer until the shoulder i of the trigger takes under the nose b and the extremity
of projection e comes into contact with the top of b, as in Figure 1. The hammer
is then at half cock ready for the next movement. If instead of being raised by
the trigger the hammer were to be cocked by the thumb, the nose b would lift the
projection e of the trigger until the one engages in the notch of the other, as
shown in Figure 2.
In applying the Invention to other than revolving fire-arms, the pawlf would
be dispensed with and the extension of the lower branch of spring g would be
made to act directly upon the trigger d.

page_text: Having described the nature of our Invention of " Improvements in the Locks of
Fire-arms" and the manner of performing the same, we declare that what we claim
as our Invention to be protected by the hereinbefore in part recited Letters
Patent is.
1st. In combination with the hammer a as described, the trigger d made to act
directly on the said hammer and lift it up without using any intermediate piece,
substantially as shown and described.
2nd. The small spring m formed with the main spring g and acting as described
to allow the trigger to pass again under the hammer when the said hammer is
brought to half cock.
3rd. In combination with the hammer a and trigger d as described, the double
branched spring g, the lower branch of which is provided with a flat part / having
a small spring m formed with it as and for the purpose specified.
In witness whereof I the said Edouard Bled for myself and on behalf of the
said Edmond Richoux and Jean Warnant have hereunto set my hand and
seal this Twelfth day of June, A.D. 1882.
