Year: 1876

page_text: LETTERS PATENT to the Baron Thornton de Mouncie, of Paris, Franco, now
of Queen Victoria Street, in the City of London, for the Invention of "IM-
PROVEMENTS IN REVOLVING CYLINDER PISTOLS."
caled the 9th February 1877, and dated the 14th August 1876.
PROVISIONAL SPECIFICATION left by the said Baron Thornton de Mouncie
at the Office of the Commissioners of Patents on the 14th August 1876.
The Baron THORNTON DE MOUNCIE, of Paris, France, now of Queen Victoria
Street, in the City of London. "IMPROVEMENTS IN REVOLVING CYLINDER
PISTOLS."
This Invention relates to a revolving cylinder pistol with a ramrod or extractor,
and with a rebounding or retracting percussion lock, the putting together and
taking apart of all the mechanism being effected without the aid of any tool or
instrument.
The parts of this improved revolver are as follows, namely:-A cylinder or drum
containing several chambers placed immediately behind the barrel, and revolving
upon a rod or axis; a percussion lock, which retracts without the aid of any special
or supplementary arrangement; the form of this part causes it to take up its
proper position in the safety notch after each shot; a trigger, to which is pivoterl
the hammer bridle that acts as a guide; by pressing with the finger on the trigger
the hammer bridle is caused to rise, and to be put in gear with the rack, which is
plain at the rear edge of the cylinder, which has a tendency to a rotatory motion,
and places at each revolution a fresh cartridge in front of the hammer; a flat
spring causes the covering of the lock to shoot out as soon as the latter becoming
disengaged from the pedal; the hammer bridle acts as a guide, causing the cylinder
to revolve around its rod.
The aforesaid pedal, which travels from the front backwards, is kept in place by
a spring, and serves as a closing key to the covering piece.
ย
A spring with a double branch has its large branch arranged to act also as
tumbler, and work simultaneously with the trigger on the hammer bridle, and the
small branch on the percussion lock.
The extractor or ramrod has a movable head turning back upon the head of
the rod.
This arm is distinguished by a great simplicity of construction, and great

page_text: strength of the parts; there is not a single screw throughout the mechanism; it is
taken to pieces and put together by the hand without the aid of any tool whatever ;
spring setters and screwdrivers are dispensed with.
In order to take the said revolver to pieces the cylinder rod is first disengaged, than
the cylinder is removed after having pulled down the closing plate towards the right;
in the cylinder rod at the head I form a notch; the hammer is to be placed at
full cock, and the two branches of the large spring are seized in this notch at the
head of the rod; the mainspring thus compressed is then disengaged gently from
its position, and the hammer and trigger are set free; then these two pieces being
romoved the revolver is completely dismounted or taken to pieces.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Baron Thornton de Mouncie in the Great Seal Patent Office on the
14th February 1877.
The Baron THORNTON DE MOUNCIE, of Paris, France, now of Queen Victoria
Street, in the City of London. " IMPROVEMENTS IN REVOLVING CYLINDER
PISTOLS."
This Invention relates to a revolving cylinder pistol with a ramrod or extractor,
and with a recoiling or rebounding striker or hammer, and whose parts are so con-
structed that the putting together and taking apart of the mechanism may be
effected without the aid of any tool or implement.
The construction of this improved revolver is shown in the accompanying Drawing,
in which,―
Figure 1 is a side view of a revolver constructed according to my Invention.
Figure 2 is a view of the opposite side of the said revolver shewing some of the
parts removed.
The remaining Figures shew portions of my Invention detached.
Like letters indicate the same parts throughout the Drawing.
A is the cylinder or drum containing several chambers, and placed immediately
behind the barrel; this cylinder revolves upon the rod or axis A¹; B is a cock or
hanmer, which recoils or falls back without the aid of any special or supplementary
arrangement for this purpose; the form of this part causes it to take into the
safety notch after each discharge; C is the trigger, to which is pivotted the lifter
or pusher E, that also acts as a guide; by pressing with the finger on the trigger
the said lifter is caused to rise, and gear with the rack or series of notches formed
at the rear of the cylinder, which is thereby caused to rotate, and at each movement
to bring a fresh cartridge in front of the hammer; D is (the covering of the lock,
which is acted upon by a flat spring, whereby it is caused to fly open as soon as it
is disengaged from the key F; this key, which moves to and fro endwise, is
kept in place by a spring, and serves to lock the covering plate D.
H is the mainspring with a double branch; its long branch is arranged to act as
a tumbler, and works simultaneously with the trigger on the lifter E, and the short
branch acts on the hammer B; I is the extractor or ramrod, which has a moveable
head arranged to turn back upon the head of the rod A¹.
Figure 2 shows the cover D open to permit access to the lock.
Figure 3 is a side view of the cylinder.
Figure 4 is a side view of the hammer.
Figger 5 is a side view of the trigger.
Figure 6 shews side and edge views of the lifter.
Figure 7 shows side and top views of the mainspring.
Figure 8 shows side and end views of the cylinder rod or axis.
This pistol is distinguished by its great simplicity of construction, and the great
strength of its parts; there is not a single screw employed throughout its mechanism;

page_text: it is taken to pieces and put together without the aid of any tool or implement, so
that the screwdrivers and other implements ordinarily required are dispensed
with.
In order to take the said revolver to pieces the cylinder rod is first drawn out,
then the cylinder is removed, and the covering or closing plate is opened; in
the cylinder rod A¹ at the head there is a notch; the hammer is to be placed at
full cock, and the two branches of the mainspring are seized in this notch; the
mainspring thus compressed is then disengaged gently from its position, and the
hammer and trigger are set free; then these two parts being removed the revolver.
is completely dismounted or taken to pieces.
Having thus fully described my said Invention, and the manner of performing
the same, I wish it understood that I claim in and forming part of a revolving
cylinder pistol,
-
First. The covering plate hinged to the frame in such a manner that it may be
opened to permit access to the lock, and may be closed and locked or secured by the
key or other suitable device, as above set forth.
Second. The lock, consisting of the mainspring, the trigger, the lifter, or guide,
and the hammer or striker, constructed and combined as shown in the Drawing, and
operating as above set forth.
Third. The construction and arrangement of the parts of the lock, as shewn in
the Drawing, and as above described, so that the same can be put together or taken
apart without tools or implements in the manner specified.
Fourth. The hammer and mainspring, constructed and combined in such a manner
that one spring serves the double purpose of forcing the hammer forward and
causing its recoil, as above set forth.
Fifth. The combination of the aforesaid parts of the lock and the hinged covering
plate with the other parts of the pistol, as shewn in the accompanying Drawing,
and as above set forth.
In witness whereof, I, the said Baron Thornton de Mouncie, have hereunto
set my hand and seal, this Thirteenth day of February, in the year of our
Lord One thousand eight hundred and seventy-seven.
